Abstract

Obesity affects physical and psychological health and impacts society (Ogden et al.,

2006). Internet bariatric support groups may help in weight loss and are largely

unexplored (Wing & Hill, 2001). This pilot study aimed at describing such groups.

Twenty two members of internet bariatric support groups completed a survey.

Information on demographics, weight loss, support group and psychological co-

morbidities was gathered. Quality of life (QOL) was measured using the World Health

Organization Quality of Life Index (WHOQOL group, 1996). Results indicate differences

in QOL and psychological co-morbidities by age, gender, experience with weight loss

and surgery and group structure. Larger samples are suggested to explore these trends

further. Results may guide recommendations for participation in online bariatric support

groups.

Introduction

Obesity – the scope of the problem

Obesity is a national epidemic which affects individuals’ health, psychological

well-being and has far-reaching impacts on our society. The prevalence of obesity in

adults in the United States was estimated to be 32.2% in 2003-2004 (Ogden et al., 2006).

Overweight is defined as 20% or more over ideal body weight for height, age and sex.

Severe obesity is at least 100% overweight or body mass index (BMI) greater or equal to

40 kg/m2. It has been estimated that 0.5% of the overweight population are severely

obese (Brownell, 1995). Severe obesity is associated with increased risk for developing

hypertension, hypertrophic cardiomyopathy, pulmonary insufficiency, degenerative

arthritis, dyslipidemia, non-insulin-dependent diabetes mellitus, gallbladder disease,

certain types of malignancies, and plays a role in individual’s socio-economic and

psychosocial impairment (National Institutes of Health Consensus Development

Conference Panel, 1991). It is also associated with increased mortality (Drenick, Bale, &

Seltzer, 1980; Lew & Garfinkel, 1979; VanItallie & Lew, 1992).

Treatments

Treatments that are often effective for mild to moderate obesity, such as behavior

therapy and the use of various diets, including very low calorie diets, are usually

ineffective for severe obesity (Stunkard, Stinnett, & Smoller, 1986; T. A. Wadden, 1993).

The same holds true for pharmacological agents given on their own, such as the case for

the most widely publicized combination of d-fenfluramine and phentermine (Goldstein &

Potvin, 1994). Because of lack of efficacy with nonsurgical interventions, the National

Health Institutes Consensus Development Panel in 1991 recommended that gastric

Page 11: A Study of Online Bariatric Support Groups and Their Participants

restriction or bypass surgery should be considered for well-informed, motivated, severely

obese individuals in whom surgical operative risks are acceptable(National Institutes of

Health Consensus Development Conference Panel, 1991). Panel also recommended that

some less severely obese patients with BMI between 35 and 40 kg/m2 should be

considered for surgery if they have developed high-risk, comorbid conditions or

conditions that interfere with lifestyle as a result of their obesity. This decision has a far-

reaching impact, as approximately 4 million Americans have a BMI between 35 and 40

kg/m2, and 1.5 million have a BMI over 40 kg/m2.

Psychological aspects of obesity

The number of bariatric surgeries conducted in the United States increased nearly

450% between 1998 and 2002 (Nguyen, Root, & Zainabadi, 2005) and further doubled

over the following two years (T. Wadden, Sarwer, & Williams, 2006). Bariatric surgery

is technically demanding and carries significant risk of complications, including mortality

which is estimated between 0.3% and 1.6% (Brolin, Robertson, & Kenler, H. A. et al,

1994; Kellum, Kuemmerle, & O’Dorisio, T. M. et al, 1990). Limited research exists in

the field describing motivations among patients choosing to undergo the bariatric surgery.

In one study 32% of patients endorsed psychological and body image related reasons as

their primary motivation to seek bariatric surgery compared to 24% who were motivated

primarily by their current medical condition (Foster, Wadden, & Phelan, 2001). Munoz &

Lal found 73.4% of respondents endorsed current medical ailments as their primary

reason for seeking weight loss surgery, and self-esteem was the primary motivation in

only 3% of patients (Munoz et al., 2007). The discrepancy and the paucity of data

Page 12: A Study of Online Bariatric Support Groups and Their Participants

3

pertaining to the psychological factors influencing the decision to undergo the bariatric

surgery highlights the importance of further research in this field.

It is important to note that there is no consensus in the field of bariatric

psychology as to whether obesity by itself is associated with psychiatric disturbances.

Studies on psychopathology among the obese found no increase in psychiatric

disturbances among the mild to moderately overweight individuals, whether or not they

sought treatment for weight reduction (Stunkard & Wadden, 1992). In contrast, several

studies have found a high rate of psychopathology among severely obese subjects seeking

treatment for weight loss: the life-time prevalence of major depression among this

population varied from 29% to 51% (Berman, Berman, & Heymsfield, 1993; Goldsmith,

Anger-Friedfeld, Beren, Boeck, & Aronne, 1992; Halmi, Long, & Stunkard, A. J. et al,

1980). Although these studies did not analyze control groups and hence must be

interpreted with a great deal of caution, these numbers are noticeably higher than the

prevalence of major depression in the general population, estimated between 4.2 and

17.1% (Kessler, McGonagle, & Zhao, 1994; Robins, Helzer, & Weissman, M. M. et al,

1984).

Several investigators have found that preexisting major depression does not affect

the weight-loss outcome of bariatric surgery (Halmi et al., 1980; Valley & Grace, 1987).

However new episodes of depression may occur in some individuals after surgery. In one

study 40% of severely obese patients with no history of depression developed depression

after surgery and 50% of those required treatment for depression (Ryden, Olsson, &

Danielsson, 1989). A high rate of suicide in post bariatric surgery patient population is an

alarming outcome of psychological problems present in these patients. Hsu et al. (1998)

Page 13: A Study of Online Bariatric Support Groups and Their Participants

4

reviewed four cohorts of patients followed after bariatric surgery for a period of 1 to 14

years (Capella & Capella, 1996; L. K. G. Hsu, Benotti, Dwyer, Roberts, Saltzman, &

Shikora, 1998; Macgregor & Rand, 1993; MacLean, Rhode, & Forse, 1990; Pories,

Swanson, & MacDonald, K. G. et al, 1995). Among 1785 subjects there were 8 suicides

(0.4%), which is in stark contrast to suicide rate among the general population, reported

to be 0.014% (Caruso, ; National Institute of Mental Health, 2009). It is clear that

bariatric population might have a greater prevalence of psychopathology in general and

the surgery, although being effective with short-term weight loss, can sometimes have

adverse effects on psychological well-being of patients, especially for those dealing with

multiple complications (Ryden et al., 1989). Van Hout et al. (2006) found a significant

minority of their subjects who experienced negative psychological effects following

bariatric surgery (van Hout, G. C. M., Boekestein, Fortuin, Pelle, & van Heck, 2006).

Maddi et al. (2001), however, found the opposite positive effect of bariatric surgery on

psychological functioning (Maddi et al., 2001). It is therefore reasonable to propose that

this population should be more carefully followed by mental health care workers and

more data is necessary to identify individuals at risk and intervene successfully at

appropriate stages.

Support groups

Many studies have found that bariatric surgery leads to improvement in

socioeconomic performance and psychosocial functioning, and that patients experience

an increase in social acceptance after weight loss (Bull, Engels, Engelsmann, & Bloom,

1983; Harris & Green, 1982; Larsen & Torgersen, 1989; Rand, Kuldau, & Robbin, 1982).

Other studies have found that the patients’ initial postoperative improvement in

Page 14: A Study of Online Bariatric Support Groups and Their Participants

5

psychosocial functioning had largely dissipated by 3 years after the surgery, even among

those with good weight and health outcome (Pories, 1991). It is possible that new social

skills are often required to cope with increased social acceptance, and creation of new

social structures is critical to these patients. Support groups might play an important role

in the psychological well-being, psychosocial functioning and even long-term weight loss

maintenance and medical outcome for bariatric patients.

Social support groups exist in all spheres of health and psychological

environments. Eysenbach et al. (2004) reviewed 45 publications on effect of health

related virtual communities and electronic support groups and found a lack of studies

which focused on isolating the effects of online support groups controlling for other

interventions (Eysenbach, Powell, Englesakis, Rizo, & Stern, 2004). Smoking cessation

was by far the most common theme analyzed with some mixed results, but overall a

positive trend. Depression, social support in general, healthcare use, eating disorders,

weight loss and diabetes control were additional domains in which studies have been

conducted. These publications most often studied depression and social support as

outcomes and the majority of them did not find an effect. Authors also concluded that

there was no evidence to support concerns over virtual communities harming people

(Eysenbach et al., 2004).

Despite the prevalence of peer support groups in the community, the evidence for

their effects on well-being is mixed at best. Support groups for people with cancer

(Helgeson & Cohen, 1996), caregivers (Bourgeois, Schulz, & Burgio, 1996; Lavoie, 1995)

people facing the transition to parenthood (Cowan & Cowan, 1986), people recently

divorced (Hughes, 1988), and people who have been victimized (Coates & Winston,

Page 15: A Study of Online Bariatric Support Groups and Their Participants

6

1983) do not show clear benefits. One possible explanation for mixed data might come

from the fact that some individuals benefit from the support group intervention, some are

unaffected, and some are even harmed. Biased or unbiased selection of particular

individuals therefore affects the studies’ outcome. In the field of cancer peer support

groups, Andersen (Andersen, 1992) suggested the level of support from family and

friends might moderate the effectiveness of an intervention. People with more

problematic social relations might benefit the most from a peer support-group

intervention. This premise was partially based on findings that new cancer patients have

not experienced any benefit from the peer support group participation because they were

satisfied with their social network relations (Wandersman, 1982). More recently a study

of women with breast cancer has shown that peer discussion groups were helpful for

women who lacked support from their partners or physicians, yet harmful for women

who had high levels of support (Helgeson, Cohen, & Schultz, 2000).

Support groups relating to obesity

As obesity is considered a chronic medical condition by many professionals –

with the typical attributes of such illnesses, including an almost-normal life span, choice

of various interventions, potential for symptomatic regression as well as recurrence of

signs and symptoms of the condition – the study of effect of peer support group in the

bariatric population is a formidable task in a largely unchartered field. There are very

limited controlled studies demonstrating that peer support group works for weight loss

and weight loss maintenance, and no study to date evaluated the psychological aspects of

this intervention. The Weight Watchers program is the only major national weight-loss

program with a published clinical trial lasting 2 years. Individuals who were assigned to

Page 16: A Study of Online Bariatric Support Groups and Their Participants

7

the groups with most weekly meetings maintained the largest weight loss during the 2-

year study period. Overall, the Weight Watchers group lost 5.3% of initial weight at 1

year and maintained a loss of 3.2% at 2 years, whereas the control self-help intervention

arm lost only 1.5% of initial weight and did not maintain any weight loss at 2 years

(Heshka et al., 2003).

Internet-based support groups

Support groups using computer-mediated communication offer a new delivery

mechanism for psychological services, yet the functioning and efficacy of these

electronic support groups remain largely unexamined. In the early 1990s, internet-based

support groups for specific medical conditions emerged (Ferguson, 1996). An estimated

33 million Americans have used the internet as a health resource (Miller & Reents, 1998).

By the year 2000 internet access had expanded to reach 41.5% of American households

(National Telecommunications and Information Administration, 2000). Internet support

groups operate both asynchronously, largely via emails, or synchronously. Most internet

groups employ asynchronous communication, which involves the composition of

message off-line that are then sent to individuals or to larger groups.

With the development of internet support groups, individuals have formed virtual

communities where members regularly communicate, form relationships, and provide

information and support to one another (Rheingold, 1993). People participate in virtual

communities and find the opportunity to converse electronically with others they might

never meet face-to-face. Studies show that individuals using internet groups

communicate more frequently, emphasize the merit of message over the status of

communicator, encourage wider participation from group members, and express greater

Page 17: A Study of Online Bariatric Support Groups and Their Participants

8

candor in their communication than people who communicate face-to-face (Kim, 1994;

Kollock & Smith, 1996). Electronic communication offers many advantages over face-to-

face support group format. The greatest advantage is that members need not be physically

present for the group to function. These groups can be used conveniently by people

worldwide, and users can participate at any time.

With continuous availability participants are able to obtain support whenever

necessary without burdening their own existing support system, such as family, relatives,

coworkers and friends, at inconvenient times. Reluctant or shy members can also feel

more comfortable by inactive participation until they gain confidence to request or

provide support directly. These groups do not require financial support, minimize

differences in social status among the participants, allow for uninhibited discussion, and

provide significant anonymity to participants (Schneider & Tooley, 1986). At the same

time, internet-based forums are not without potential problems. Low motivation, lack of

personal and immediate contact and longer time periods required to develop trust in the

group may interfere with the effectiveness of the support group intervention. Because

members of internet group may not receive immediate feedback on their comments, a

climate of warmth and concern may take longer to develop in internet-based forums than

in face-to-face groups. More importantly, however, as participation is largely open to

anyone with access to the server, there is little control over who may participate in the

group, the regularity and length of a member’s participation, and the accuracy of

information and feedback provided to group members.

Given the potential benefits and the rapid growth in the number of internet-based

support groups, it is surprising how little is known about the functioning and the efficacy

Page 18: A Study of Online Bariatric Support Groups and Their Participants

9

of these groups. The first report was published in 1986, evaluating the effectiveness of an

online behavioral smoking cessation program (Schneider & Tooley, 1986) which lacked

control arm and therefore its largest merit was the introduction of the novel methodology.

In the Alzheimer’s caregivers’ study the use of the internet-based support group led to a

greater perceived confidence in the ability to care for family members (Gallienne, Moore,

& Brennan, 1993). In an AIDS trial, use of the computer-based communication system

reduced self-reported isolation (Brennan, Ripich, & Moore, 1991). Analysis of messages

posted on eating disorder electronic support group revealed that self-disclosure was the

main reason for posting, amounting to 31%, followed by requests for information (23%)

and the direct provision of emotional support (16%) (Winzelberg, 1997). Characterization

of an internet support groups for patients with depression revealed that users had high

depression severity scores, were socially isolated and perceived considerable benefit from

the group. Moreover, heavy users of the internet groups were more likely to have

resolution of depression during follow-up than less frequent users, whereas social support

scores did not change during follow-up (Houston, Cooper, & Ford, 2002).

Internet-based bariatric support groups

The research on bariatric internet-based support groups is lacking, with the

existing literature focusing primarily on weight loss outcome. Wing et al. (2006) found

the amount of weight regain was significantly greater in the control group compared with

face-to-face or internet-based intervention groups (Wing, Tate, Gorin, Raynor, & Fava,

2006). However, this was a directed intervention by method of an internet-based

communication, and not an analysis of a self-formed community created around the

theme of weight loss. What is currently lacking in the field is a detailed characterization

Page 19: A Study of Online Bariatric Support Groups and Their Participants

10

of this entity to pave the way for further analysis of the effect of these communities on

health-related and psychological well-being of its members.

A convenient and inexpensive methodology for reaching members of online

groups and conducting a study of online support groups is via an electronic survey.

However, electronic surveys have distinctive technological, demographic, and response

rate characteristics that affect their design, distribution, and response rates (Sohn, 2001).

Surveys are imperfect vehicles for collecting data. They require participants to recall past

behavior that can be more accurately captured through observation (Schwarz, 1999). The

lack of internet central registries prevents researchers from identifying all the members of

an online population along with multiple email addresses for the same person and invalid

or inactive email address. Most important, electronic survey selection is limited to

nonrandom and probabilistic sampling (Cooper, 2000; Dillman, 2000). Nevertheless,

web-based surveys are the most appropriate format for surveys when research costs are a

constraint, timeliness is important and the nature of the research requires it (Andrews,

Nonnecke, & Preece, 2003). Piloting and preliminary analysis was shown to improve the

participants’ response rates, increase compliance among hard-to-involve online

population (Andrews et al., 2003).

Characterization of a bariatric internet-based support community is a critical

aspect of research into one of the cornerstones of successful weight loss maintenance and

psychosocial well-being of obese patients. Electronic survey appears to be the most

suitable method for this task and a pilot characterization of this community is the first

task towards achieving the overarching goal of robust assessment of the communities’

effect on long-term health benefits and psychological well-being.

This study aims at describing online bariatric support group communities and

their participants, including participants’ experience with weight loss process and

bariatric surgery and medical care, their experience related to their participation in online

support groups and their self-reported quality of life and psychological co-morbidities.

Method

Participants

Members of online bariatric support groups were recruited to participate in an

observational cohort study. A total of 39 people participated in the study, including males

and females 34 to 64 years of age. Additional demographic data is presented in Table 1.

Procedure

Participants were recruited by means of posting an invitation to take a survey on

several online bariatric support group websites. Online support groups were chosen from

Facebook.com, yahoo groups, and by searching the internet. A description of the study

along with an agreement to conduct research form was e-mailed to group leaders or

webmasters listed on each support group website. Upon receipt of an e-mail response and

agreement to conduct research from group leaders or webmasters an invitation to

participate in a survey along with a link to the survey was posted on the main website of

each online support group. Upon following the link to the survey participants first read

and acknowledged the study description and the informed consent giving their permission

to the researcher to gather data. The participants then took the survey containing several

questionnaires (Appendices A-G). The study was anonymous in nature. Participants were

not compensated for completing the survey. Participants were not debriefed after the

study due to its transparent nature.

Measures

Participants completed the survey through online survey software SurveyMonkey.

The questionnaire consisted of five parts: Demographics questionnaire (Appendix A),

Page 22: A Study of Online Bariatric Support Groups and Their Participants

13

Questionnaire on weight (Appendix B), Questionnaire about online support group

(Appendix C), Social support and quality of life questionnaire (Appendix D), including

WHOQOL-BREF (World Health Organization Quality of Life Index) (Appendix E)

(WHOQOL group, 1996), and Psychological co-morbidities questionnaire (Appendix F).

Demographics Questionnaire

Demographics Questionnaire was used to gather basic demographic information

in a multiple choice format. Questionnaire on Weight was used to gather information

about participants’ current and previous weight, their weight loss practices and attitudes,

and their experience with bariatric surgery, in a multiple choice format. Questionnaire

about Online Support Group was used to gather information about participants’ current

participation in a specific online bariatric support group, their past experiences

participating in other online bariatric support groups and their current experience with

medical care following bariatric surgery, in a multiple choice and 5-point Likert rating

scale format.

Social Support and Quality of Life Questionnaire

Social Support and Quality of Life Questionnaire was used to gather information

about participants’ perception of social support they received, degree of isolation and

quality of life.

WHOQOL-BREF

Included in the Social Support and Quality of Life Questionnaire of the survey

was WHOQOL-BREF (World Health Organization Quality of Life Index), a 26-item

self-report measure, which was used to gather information about participants’ general

quality of life, in the domains of physical (Domain 1) and psychological (Domain 2)

Page 23: A Study of Online Bariatric Support Groups and Their Participants

14

health, social relationships (Domain 3) and environment (Domain 4) (WHOQOL group,

1996), in a 5-point Likert rating scale format. Overall, WHOQOL-BREF appeared in the

literature to have good psychometric properties in an international study using a large

sample of healthy people and individuals with mental and physical problems. Cronbach’s

alphas were acceptable (>0.7) for Domains 1, 2 and 4, i.e. physical health 0.82,

psychological 0.81, environment 0.80, but marginal for social relationships 0.68.

Discriminant validity was best demonstrated in the physical domain, followed by the

psychological, social and environment domains. Item–domain correlations ranged

between 0.48 for pain, to 0.70 for activities of daily living (Domain 1), from 0.50 for

negative feelings to 0.65 for spirituality (Domain 2), from 0.45 for sex to 0.57 for

personal relationships (Domain 3) and from 0.47 for leisure to 0.56 for financial

resources (Domain 4). (Skevington, Lotfy, & O’Connell, 2004)

The WHOQOL-BREF measure was scored according to the scoring instructions

specified by the WHOQOL group (WHOQOL group, 1996). (Hawthorne, Herrman, &

Murphy, 2006) reported preliminary general community norms for interpreting

WHOQOL-BREF. Their results showed that general norms for the WHOQOL-BREF

domains were 73.5 (SD = 18.1) for the Physical health domain, 70.6 (SD = 14.0) for

Psychological wellbeing, 71.5 (SD = 18.2) for Social relationships and 75.1 (SD = 13.0)

for the Environment domain. In general scores declined slightly by age group, according

to the authors. For females scores were stable across the lifespan with an accelerated

decline after the age of 60 years. Males exhibited a more consistent and even decline

across the lifespan. There were significant differences in WHOQOL-BREF scores when

Page 24: A Study of Online Bariatric Support Groups and Their Participants

reported by health status, with those in poor health obtaining scores that were up to 50%

lower than those in excellent health.

Psychological Co-morbidities Questionnaire

Finally, Psychological Co-morbidities Questionnaire was used to gather basic

information about possible psychological co-morbidities, in a Yes/No question format.

Outcomes and Analysis

Our main outcome was quantitative and qualitative characterization of bariatric

internet-based support groups, using the pooling of descriptive variables and scoring from

WHOQOL-BREF measure. The data were examined for missing data points. Individuals

who did not complete the entire survey were excluded from the data analysis. Descriptive

statistics and summaries of data were used to interpret the information about the sample.

A Pearson product-moment correlation was used to examine the relationship between

BMI change and group satisfaction.

Results

Of 39 people who took the survey 22 completed the entire survey, yielding a 56%

survey completion rate. The majority of participants were white females over 45 years

old. Table 1 summarizes demographic information of respondents broken down by

whether a survey was completed or only partially completed. All of the results presented

were collected from current members of online bariatric support groups.

Participants of sampled online bariatric groups have been trying to lose weight for

25 years on average (range = 3-57 yrs) and sixty one percent of participants reported it

Page 27: A Study of Online Bariatric Support Groups and Their Participants

18

was “extremely difficult” to lose weight. Eighty one percent of respondents underwent

some type of weight-reduction surgery. The surgeries listed can be grouped into the

following categories – 66% Roux-en-Y Gastric Bypass, 24% Lap Band, with 6%

remaining unspecified. Participants reported having a surgery on average 1.9 years (range

0-9.7 years) before the survey was conducted. From the height and weight information in

the survey BMI was calculated for each participant at three points in time: prior to

surgery, at the time of joining online support group and current (at the time of taking the

survey). Pre-surgery BMI of respondents is summarized in Figure 1.

Participants indicated medical reasons and improving physical quality of life as

the most important reasons for seeking bariatric surgery. Secondary reason was mainly

improving physical quality of life (see Table 2 for details).

Overall the majority of respondents reported to have lost the weight they intended

(75%) with little or minor difficulties in keeping the weight off. Consistent with this is

that majority of participants also reported being satisfied with the result of the surgery

(see Figure 2 for a detailed report). Also noteworthy is that 89% of respondents reported

they engaged in little to moderate amount of physical activity of “less than two hours a

week” or “two to eight hours a week” (each reported by 44%).

The main reasons for joining online bariatric support group were divided between

receiving support and encouragement (36%), providing support and encouragement

(20%), sharing experience (16%) and learning about a medical procedure (16%). The

length of participation in the online support group varied widely, but the frequency of

group participation was for the most part once or twice per week (see Figure 3 for details).

Tracking positive results of satisfaction with overall weight loss, the majority of

participants (64%) reported they were “fairly” to “moderately” successful in achieving

their initial goal when joining the group. Satisfaction with the online group did not mimic

satisfaction with weight loss or achieving weight loss goals. Forty two percent of

respondents were “somewhat satisfied” with their groups while 25% were “not sure.”

Sixty four percent indicated they had participated in another online bariatric

support group and 65% of people reported they were still active members of another

group. Ninety six percent of participants did not feel they spent too much time in the

group.

Respondents were asked to rate their usual mood or state of mind on a scale from

1 to 7 (from very negative, to very positive, respectively) at the time of deciding to log

into their respective online groups. The results are summarized in Table 4.

Analysis of responses by gender revealed some differences, none of which were

statistically significant due to the small number of male participants (6), however still

worthy of mention. Largest proportion of male respondents (40%) indicated they joined

the group mainly to provide support, whereas 45% of women reported they joined in

order to receive support. Men also tended to post more comments indicating a more

active participation. Also the largest proportion of male respondents (40%) reported they

were “extremely successful” in achieving their online group goal, while only 5% of

women reported being “extremely successful” (see Figure 4).

While 80% of men and 22% of women reported they participated in in-person

support groups, women preferred in-person groups (65%) while men preferred internet

groups (60%).

Participants were asked to describe their groups as either having a leader or not.

Forty eight percent reported their group having a leader, but only 20% indicated there

was an “ask an expert” feature in their forums. Among groups with leaders, 33% of

members described leaders as peers, 33% could not define the leaders precisely, 8%

described them as physicians and 8% described them as social workers. Figures 5 and 6

Participation in discussions varied widely. Forty two percent of respondents

stated that they rarely posted comments, 25% posted sometimes and 21% of respondents

usually posted comments. When participants were asked to describe the discussion

topics within their online support groups, 50% indicated socialization was present

occasionally, 46% reported sharing experiences was present in a significant portion of all

discussions, 48% reported emotional support was provided frequently, 42% reported

request for emotional support in half of all discussions, and 48% reported advice giving

present in half of all discussions. Twenty nine percent of participants indicated diet

discussions were present in a significant portion of all discussions, while another 29%

reported they were present in a significant portion of all discussions, 44% said medical

care was the topic of half of all discussions, and 32% reporting discussing exercise was

part of half of all discussions.

Respondents continued to receive medical care as pertaining to their obesity and

weight loss with medical providers. Sixty seven percent of all respondents reported

receiving follow-up care at a bariatric surgery clinic and 72% continued to see their

Page 39: A Study of Online Bariatric Support Groups and Their Participants

primary care physicians. Fifty four percent of participants were somewhat or extremely

satisfied with their follow up medical care. When asked about their communication with

the doctor, 32% reported they told their doctor about the online support group and 44%

indicated participating in this group improved their communication with the doctor.

Participants of sampled online bariatric support groups reported significant levels

of psychological distress. Figure 8 summarizes the results of the psychological distress

Discussion

Evaluating bariatric support groups is an important step towards future

exploration of the impact of these groups on well-being and health status of participants

and identification of positive and negative features of these groups to help guide bariatric

patients towards optimal resources in the community and online. This is a small pilot

study that attempts to characterize online support groups. The main limitation of this

study is the small number of respondents, which does not allow for robust statistical

analysis and hence the results can only be viewed as possible trends, needing further

verification and validation. The second limitation is intrinsic to electronic survey

methodology (Andrews et al., 2003) – only responses of those who responded to the

questionnaire are analyzed and therefore cannot be generalized to the entire online

community. These limitations must be considered carefully when using the data

generated by this pilot study. Nevertheless, these findings provide a preliminary platform

for further characterization of this entity growing in size and popularity.

Demographic analysis, as presented in Table 1, indicates that the majority of

participants are no older than 54 years of age, which could be associated with a higher

computer literacy rate in younger population (Horrigan, 2008; J. Hsu et al., 2005).

However if we consider the quality of life scores in Table 7, it appears that with age

quality of life in online bariatric group participants improves. Likewise, based on

responses generated by this survey, more women participate in support groups, and

women in our study had lower quality of life scores across all four domains (Table 8). It

is therefore possible, that those seeking psychological support online are those with

worse quality of life scores. This hypothesis could be further investigated among bariatric

Page 46: A Study of Online Bariatric Support Groups and Their Participants

37

patients in clinics to compare the quality of life scores among those who chose to

participate in online discussions and those who do not.

Almost all respondents were white, as opposed to a largely equal distribution

across education background and household income. It would be extremely important to

determine whether this is a true phenomenon – and only white bariatric patients seek

online support groups, or this is influenced by the inability or lack of desire to participate

in our and other survey studies, therefore skewing the true representation of other races in

these electronic groups.It is interesting to note that in Munoz et al study of patients

seeking bariatric surgery the sample was overwhelmingly female (N = 88, 81%), and

approximately two-thirds Caucasian (N = 69, 63%)(Munoz et al., 2007).The trend of a

higher proportion of white members in support groups in general can be seen in studies

pertaining to other health issues. For example, in a study of breast cancer group support

interventions conducted in racially diverse city of Pittsburg, Pennsylvania, 93% of

women were Caucasian (Helgeson et al., 2000).

The majority of patients in our survey were married or in a relationship. Of

contrast, internet support groups for depression had a higher proportion of socially

isolated members, with over half of members unmarried (Houston et al., 2002). This

comparison suggests that there is no universally identifying description of online

community members, but rather each community has specific characteristics based on the

underlying health-related issue. Moreover, participants who lived with a partner had

lower quality of life scores across three of the four domains – physical health,

psychological health and environment domains (Table 12). This also reinforces our

Page 47: A Study of Online Bariatric Support Groups and Their Participants

38

previous observation that more members with lower qualify of life scores seek

participation in online bariatric communities.

Survey responses showed a relatively consistent distribution of participants from

high school level to graduate degree and across various income levels. This is in line with

previously published assessment of online support groups and their effect on

minimization of differences in social status among the participants (Schneider & Tooley,

1986).

Eighty one percent of respondents in this survey underwent weight-reduction

surgery. This is an important aspect of this population cohort. Several interpretations

could be proposed. These members might bond and continue online dialogue centered

around a common experience, in this case the weight reduction surgery. Alternatively,

people who are drawn to either in-person and/or online support groups are those who

seek active management and hence there is a higher representation of those who have

already sought a surgical intervention, which is clearly advocated by medical authorities

as the most effective method of weight loss. Further characterization of this population

might give answers to this dilemma and offer new insights into organization and function

of online bariatric support groups.

Munoz et al. (2007) analyzed patient motivation before weight reduction surgery

and found that medical health was the main motivation in 73% of patients, whereas

physical quality of life in only 1%. In this survey of patients who already underwent

surgery, medical reasons accounted for 40% and improvement of physical quality of life

for 30%. The differences in these numbers could be due to self-recall bias, inherent

differences in clinic and online bariatric populations, and the research methodology. It

Page 48: A Study of Online Bariatric Support Groups and Their Participants

39

would be important to further characterize the motivation in online patients who have not

yet undergone surgery in order to establish whether bariatric patients participating in

online communities differ from those who do not in terms of their motivations factors for

undergoing surgery.

Our survey asked participants to determine whether they were able to achieve the

desired weight loss after surgery. Unfortunately, we do not know what that desired

weight loss was a priori. Nevertheless, the individual’s self-assessment of that

achievement is likewise a critical factor and should not be overlooked. Forty six percent

of respondents stated that it was easy to keep weight off after surgery. When Wing & Hill

(2001) defined maintaining 10% of intentional weight loss at 1 year as weight-loss

success, they found in their National Weight Control Registry that only 20% of their

subjects were able to achieve this goal (Wing & Hill, 2001). Moreover, 64% of our

respondents were content with their weight loss. It would be very important to determine

in future studies whether self-perceived success correlates with scientifically defined

parameters.

Alternatively, members of the subpopulation of the online bariatric community,

who have already undergone surgery, could be enriched by individuals who were

successful at maintaining their weight, if compared to the general post-surgical bariatric

population. If true, further comparison of online population to the general population

might yield answers to why these patients achieve greater success to increase the

effectiveness of surgery and other methods in general population.

It is striking that members were roughly divided in terms of goals from online

group participation between those seeking support and those wishing to provide it. Indeed,

Page 49: A Study of Online Bariatric Support Groups and Their Participants

40

the search for further medical information was limited to a minority of participants. This

finding fits well with analysis of mood at the time of electronic discussion. It appears

congruent that the decision to give a hand to a fellow member is accompanied by a

concomitant lack of negative mood.

The analysis of data by gender revealed interesting trends. Women in our survey

tended to be less successful in achieving intended weight loss, had a worse mood at the

time of log in and, overall, preferred in-person mode of group communication, when

compared to men (Figure 4). This correlates well with lower quality of life scores in

women, when compared to men in our survey (Table 8). However, due to small numbers

this correlation must be viewed with great caution and healthy skepticism until further

data is obtained and statistical analysis is performed.

Gravitation of members towards groups with a leader or without one might be

intrinsic to individual needs, personality traits or reasons to join the online community.

There was a trend towards more difficulty with achieving weight loss among members

who were members of groups with a leader (Figure 6). It might be explained by the fact

that these individuals are seeking counseling and need a figure of authority, more so than

members more successful in their goals and joining the groups for the sole reason of

sharing their positive experiences. At the same time members without a leader also feel

that the group has more effect on their ability to lose weight than members in groups with

a leader. It would be critical to determine whether there is indeed an outcome effect or

this difference simply represents self-selection bias. Only a randomized trial of assigning

bariatric patients to either a group with a leader or to a leaderless group would be able to

Page 50: A Study of Online Bariatric Support Groups and Their Participants

41

answer this question and therefore be further promoted in medical community for better

bariatric outcomes.

Analysis of differences in responses by the surgical status reveals the following

trends. Among members who did not undergo surgery, there were no men in our survey.

These members have been part of the online community for less than one year, in contrast

to post-surgery members, among them 37% were members for longer than one year. A

possible explanation could be that most pre-surgery patients either end up undergoing

surgery within a year or stop participating in the online community. Determining the

outcome for these pre-surgery patients at the end of one year would be a useful

investigation for further targeting this population in the event they stop seeking further

medical attention while continuing to be overweight.

Members’ satisfaction with medical care is rather poor, considering that only 54%

of participants were somewhat or extremely satisfied with their follow up medical care.

This satisfaction should be compared to the general population of bariatric patients in a

similarly anonymous fashion to determine whether this is an overall trend of poor

medical care or is intrinsic to the community seeking support online. This data could

provide more impetus for the medical establishment to improve the delivery of

information, necessary services and professional support either in general or in response

to individual needs, as could be further determined by more detailed surveys of online

bariatric community.

It is not surprising that there is a high prevalence of psychological issues among

the members of bariatric support groups, as detailed in our study. Moreover, it appears

that psychological issues are sometimes more prevalent in members who have undergone

Page 51: A Study of Online Bariatric Support Groups and Their Participants

42

surgery in comparison to those who have not, a finding which is supported by other

studies. Using projective techniques, Ryden, Olsson, & Danielsson (1989) found no

depression among 21 severely obese patients before bariatric surgery. However, 8

developed depression after surgery, and 4, including 3 with satisfactory weight loss,

required treatment for the depression. Suicide is a major cause of death after bariatric

surgery (L. K. G. Hsu, Benotti, Dwyer, Roberts, Saltzman, Shikora et al., 1998). Our

findings also indicate a trend towards a greater prevalence of suicidal thoughts in patients

who have undergone surgery. Whether depression and suicidal thoughts after bariatric

surgery occurs more commonly than expected in the general population is unclear. It is

also unclear whether the depression is triggered by the surgery, the weight loss, or other

psychosocial or biological factors. Applying data from the research of internet support

groups for depression (Houston et al., 2002), it appears that heavy users of the internet

groups were more likely to have resolution of depression during follow-up than less

frequent users. Ninety six percent of our respondents replied that that spent not a

significant amount of time online. It would be tremendously important to determine

whether heavier user of online communication with peers would lead to better

psychological outcomes for the bariatric online community members, and if so – to

determine how to promote greater access and more extensive use of this critical resource

for these patients.

Seventy seven percent of members feeling depressed and thirty two percent of

members experiencing suicidal thoughts are alarming numbers. These high rates alone

suggest that this population is very vulnerable and should be heavily targeted by social

services and medical and psychological care providers.

Page 52: A Study of Online Bariatric Support Groups and Their Participants

43

Summary and future direction

This is a small pilot study that began the process of characterization of online

bariatric support groups. It identified several interesting trends, which should be further

studied in larger surveys and ultimately in prospective trials involving participation of

patients in various support groups. Observed differences in perceived success in losing

weight and attaining goals between genders, age groups and group structure (i.e. group

expert) should be further investigated with a larger sample size. It would also be

instructive to further investigate why motivations for surgery in the online support group

were found to be different from previous studies surveying clinical patients. A separate

study could also focus on the correlation of self-perceived success with scientifically

defined parameters. Apparent dissatisfaction with the quality of medical care should also

be further looked into as it could provide valuable information on improving delivery of

information and medical services to the post-surgery population. Another important

outcome of an enlarged study would be to compare quality of life and perceived and

actual success rates of keeping the weight off to in-person support groups.

Results of this study, especially if fortified with a larger sample size and several

above mentioned follow-up investigations, could be used to enhance mental health of

post bariatric surgery patients in several important ways. Once it is clearer whether online

support groups have a positive impact on perceived and actual success rate of keeping the

weight off, the online option could be promoted as an easy alternative to in-person groups.

Once the impact of gender and group structure is better understood, health professionals

could better customize how to direct their patients for most effective results. It is clear

that patients will continue to seek the most accessible route of communication and

Page 53: A Study of Online Bariatric Support Groups and Their Participants

44

harnessing the power of this venue and directing it towards improvement in health

outcome and psychosocial wellbeing of these exceedingly vulnerable individuals is

critical if we are to successfully fight the national epidemic of obesity.

There is an important trend in medicine which is characterized by

individualization of therapies. No two people are alike, and hence no two people can be

treated in an exactly the same manner. Support groups, be it peer-to-peer, or online,

might be helpful to some, yet harmful to others. At this point the entity of online support

community is not well studied to be able to predict how a certain individual will react to

this intervention. The ability to predict the outcome of this intervention will be useful in

improving long-term outcomes in terms of weight reduction, weight maintenance and

psychological well-being. This ability hinges on our detailed knowledge of bariatric

online support groups, and this study pilots the exploration into this field.
