TRAUMATIC STRESS BACKGROUND

Page 8: Ongoing Traumatic Stress (OTS) and Post-Traumatic Stress Disorder (PTSD): The impact of cartel related violence on the U.S./México border. Thom Taylor

“Violence and Insecurity” • Extreme increase in cartel and community

related violence in northern México– Cartel related murders (2000+ in past year)– Kidnappings– Car-jackings– Robberies/Extortion (“Cuotas”)– Constant threat

• U.S. not immune• Cartel and army related violence (CARV)

– Psycho-social costs to a community– Increases stress

Caetano, 2009; U.S. Department of State, 2009; Thoumi, 2002; Chan, Air, & McFarlane, 2003

Page 9: Ongoing Traumatic Stress (OTS) and Post-Traumatic Stress Disorder (PTSD): The impact of cartel related violence on the U.S./México border. Thom Taylor

Extreme Stress Reactions• Post-Traumatic Stress Disorder (& Probable PTSD)

– Exposure to traumatic experience (s)– Feelings of fear, helplessness, and/or horror peri-event– Intrusive thoughts/Re-experiencing (1+ symptoms)– Avoidance/numbing to situations (3+ symptoms)– Hyper-arousal (2+ symptoms)– Psycho-social impairment

• Partial PTSD– Threshold for full PTSD may be too high– Impairment still seen (e.g., anger)

Acute Event PTSD: Implicit Assumptions

Page 11: Ongoing Traumatic Stress (OTS) and Post-Traumatic Stress Disorder (PTSD): The impact of cartel related violence on the U.S./México border. Thom Taylor

Identified Traumatic Stress Trends

• Chronic PTSD (> 3 months)• Acute PTSD (> 1 Month)• Resistant• Resilient

Core Trauma Symptoms

Avoidance / Numbing

Re-experiencing / Intrusive Thoughts

Hyper-Arousal

Page 18: Ongoing Traumatic Stress (OTS) and Post-Traumatic Stress Disorder (PTSD): The impact of cartel related violence on the U.S./México border. Thom Taylor

PERI Trauma (Immediate) Considerations• Unpredictable and Un-controllable• Subjective exposure

– Fear– Helplessness– Horror

• Direct forms of Trauma (e.g., assault, terrorism)• Indirect forms of Trauma (e.g., witnessing,

media, trauma by proxy-such as family member)• Subjective interpretation

Breslau et al., 2004; Gray et al., 2004; Gabriel et al., 2007; Suvak et al., 2008; Collimore et al., 2008; Foa & Riggs, 1995; Weathers & Keane, 2007

Page 19: Ongoing Traumatic Stress (OTS) and Post-Traumatic Stress Disorder (PTSD): The impact of cartel related violence on the U.S./México border. Thom Taylor

PRE-Trauma Risk FactorsDemographic risk factors (e.g., female gender)Exposure to multiple traumata (re-exposure)Anxiety disorders rarely present in pure form

– Pre-existing anxiety disorders may worsen traumatic stress after exposure

– Anxiety Sensitivity predisposes to traumatic stress after exposure

• Depression – Unclear if PRE or POST factor– Depression highly comorbid with TS post-event (correlation)– May worsen traumatic stress

Brewin et al., 2000; Ozer et al., 2003; Norris et al., 2003b; Dunner, 2001; Goldenberg et al., 1996; Elwood et al., 2009; Gabriel et al., 2007; Jaycox et al., 2003; Collimore et al., 2008; Breslau et al., 1997; Breslau et al., 1991; Breslau et al, 2000

Page 20: Ongoing Traumatic Stress (OTS) and Post-Traumatic Stress Disorder (PTSD): The impact of cartel related violence on the U.S./México border. Thom Taylor

PRE-Trauma Sources of Coping• Social support strongly buffers against traumatic stress• Coping in uncontrollable situations

– Problem focused (limited in uncontrollable situations)– Emotion-focused

• Active– Self distraction (+ or -)– Venting (+ or -)– Cognitive acceptance of situation/experience ( + or -)

• Avoidance based– Denial ( generally - )– Giving up/feeling hopeless ( - )– Self-blame ( - )– Substance use ( - )

Brewin et al., 2000; Lazarus & Folkman, 1984; Solomon, 1989; Carver et al., 1989

Page 21: Ongoing Traumatic Stress (OTS) and Post-Traumatic Stress Disorder (PTSD): The impact of cartel related violence on the U.S./México border. Thom Taylor

Unique Opportunity

• Virtually no empirical study of psycho-social impact of cartel related violence in the Americas

• Limited knowledge of real-time (daily) impact– Memory distortion after the fact (e.g., months,

years, melding of traumas? Such as in VHA situation)

– More refined understanding of impact of ongoing traumatic situations

Nisbett & Wilson, 1977; Wolfer, 1999

Preliminary Study of Ongoing Traumatic Stress

1. Assess Ongoing Traumatic Stress (OTS)2. Examine impact of factors commonly

associated with PTSD in:1. Ongoing (daily) Traumatic Stress2. Ongoing (daily) Re-experiencing symptoms3. Ongoing (daily) Avoidance symptoms4. Ongoing (daily) Hyperarousal symptoms

Measures: Main OutcomeAll measures professionally translated and

back-translated with subsequent native Spanish speakers’ input on items

Post-traumatic Stress Disorder Checklist (PCLS)– Specific event-adapted for CARV: “…violencia

relacionado con el narcotrafico u hostilidad y maltrato militar.”

– Past 30 day Acute PTSD (α = .89)Adapted version for daily traumatic stress for past 24 hours (PCLSD): α range = .91 - .94

Daily Assessment

• Completed online >24 hours for 7 days• PCLSD (daily traumatic stress)• Time-varying explanatory covariates

– Travel to CJ (# hours) – Reasons for being in CJ (family, friends,

business, antro/club/bar)– Perceived degree of exposure to violence

(fear, helplessness, horror)

Page 29: Ongoing Traumatic Stress (OTS) and Post-Traumatic Stress Disorder (PTSD): The impact of cartel related violence on the U.S./México border. Thom Taylor

Lemonade out of Lemons• Drop out rarely positive outcome, but allows

unique analysis in present study• 20% did not return for follow-up• Unique opportunity in trauma study

– Avoidance unpleasantness drop-out?– Re-experiencing unpleasantness drop-out?– Hyper-arousal unpleasantness drop-out?

Page 30: Ongoing Traumatic Stress (OTS) and Post-Traumatic Stress Disorder (PTSD): The impact of cartel related violence on the U.S./México border. Thom Taylor

Informative Drop-Out• Diggle-Kenward Selection Model (DKSM)

– Single covariate entered due to estimation complexity: Past 30 day traumatic stress (PCLS)

– Survival indicator from daily reports 3 to 4 constrained to be 0; no drop-out in interval

– To allow estimation, only intercept allowed to co-vary with past 30 day acute PCLS scores

• Drop-out unassociated with traumatic stress, all Zs < |.65|, all ps > .52

• Take Home Point: Preliminary support that asking about trauma on a daily basis does not make it worse for those assessed.

Approach to Analysis: • Multi-level modeling

– Specified Expectation-Maximization in Maximum Likelihood; robust to MAR

– Grand Mean centered variables – Standardized (N~0,1) covariates to give common scale to

psychological factors• OPTS dependent variable (PCLSD)

– Condition on demographics, LEC, DASS, MSPSS factors, BCOPE sub-scales

– Time varying covariates • Presence in CJ (hours)• Perceived exposure to violence occurring (fear, helplessness, and

horror)Snijders & Bosker, 1999; Gardiner, Luo, & Roman, 2009

DISCUSSION

Page 54: Ongoing Traumatic Stress (OTS) and Post-Traumatic Stress Disorder (PTSD): The impact of cartel related violence on the U.S./México border. Thom Taylor

Ongoing Traumatic Stress

• Border significantly affected by OTS and PTSD– Present sample might objectively be considered of

less risk (many protective factors/buffers)– Still, sample evidenced both PTSD and OTS scores

warranting concern• Assessing for PTSD can potentially help to reduce

OTS• Yet, common prior factors associated with long

term traumatic stress (PTSD) less impactful at daily levelmore nuanced?

Diamond et al., 2010; Mineka & Zinbarg, 2006; Ozer et al., 2008; Ursano et al., 2009

Page 55: Ongoing Traumatic Stress (OTS) and Post-Traumatic Stress Disorder (PTSD): The impact of cartel related violence on the U.S./México border. Thom Taylor

Evidence for Ongoing Traumatic Stress• Objective exposure (i.e., less time in Cd. Juárez) does

not reduce OTS• Very strong subjective component

– Strong peri-event subjective reactions to exposure observed– Assessment of “real time” reactions important

• Valid Anticipatory fears: the future as important as past– Unpredictability– Uncontrollability– Fear, helplessness, and horror on a daily basis– Reinforced avoidance and generalizing of fearful

situations/psycho-social states

Diamond et al., 2010; Hobfoll et al., 2009

Page 56: Ongoing Traumatic Stress (OTS) and Post-Traumatic Stress Disorder (PTSD): The impact of cartel related violence on the U.S./México border. Thom Taylor

What is not there that “should be?”

• Gender (female) unassociated with Ongoing Traumatic Stress in the present sample– Variability (model ICCs) HUGE– Other important factors to assess nested within

gender• Not “only a Mexican problem”

– Socio-economic status not explanatory either– U.S. and Mexican citizens integrated in to both

sides of border are significantly affected

Kessler et al., 1995, Ozer et al., 2008

Page 57: Ongoing Traumatic Stress (OTS) and Post-Traumatic Stress Disorder (PTSD): The impact of cartel related violence on the U.S./México border. Thom Taylor

Past/Future Exposure Considerations• Evidence for resilience from past traumata

– Much exposure already in these young adults– Little impact on traumatic stress when

accounting for other factors identified in traumatic stress literature

• Still, fear regulation strongly disrupted in traumatic stress; differentially to other anxiety disorders

• Long-term impact from short term OTS?

Bonanno, 2004; deRoon-Cassini et al., 2010; Norris et al., 2009; Dutton & Greene, 2010; Etkin & Wager, 2007; Wilson & Freer, 2010; Ginzburg et al., 2010

Page 60: Ongoing Traumatic Stress (OTS) and Post-Traumatic Stress Disorder (PTSD): The impact of cartel related violence on the U.S./México border. Thom Taylor

Other Factors to Consider: Psycho-Accumulation of Trauma?

• Re-exposure assumes a somewhat linear process• Psycho-accumulation, potentially quadratic?

Page 61: Ongoing Traumatic Stress (OTS) and Post-Traumatic Stress Disorder (PTSD): The impact of cartel related violence on the U.S./México border. Thom Taylor

Depression, Anxiety, General Stress, and Traumatic Stress

• In ongoing traumatic stress, depression may or may not be present– Few depression symptoms overall (floor effect)– Still, depression assessment likely always warranted

when assessing traumatic stress in general• Sample applies for other anxiety disorders• May meet criteria for multiple anxiety disorders (e.g., GAD)

• General stress may be one area where we can intervene for those exposed to OTS (more later)

Breslau et al., 1991; Breslau et al, 2000; Collimore et al., 2008; Breslau et al., 1997

Page 62: Ongoing Traumatic Stress (OTS) and Post-Traumatic Stress Disorder (PTSD): The impact of cartel related violence on the U.S./México border. Thom Taylor

Coping with Ongoing Traumatic Stress• Problem-focused coping difficult in

uncontrollable/unpredictable situations– Adaptive routes/variation of routes to go somewhere

in the city– Others examples from your perspective?

• Active/emotion-focused coping may not fully compensate for OTS

• Coping may be very diverse in OTS– Are some strategies helpful in one context of ongoing

violence, while harmful in others?– Many of you see coping first-hand

Riolli & Savicki, 2010; Bonanno, 2004; Lazarus, 2000; Bal et al., 2003; Ullman, Filipas, et al., 2007

Page 63: Ongoing Traumatic Stress (OTS) and Post-Traumatic Stress Disorder (PTSD): The impact of cartel related violence on the U.S./México border. Thom Taylor

Family, Familiarity, Stability • Decision to move/stay in Cd. Juárez?

– Separation from loved ones and familiarity– Family may still be exposed even if one individual family

member is safe.– “For better or worse…” (the family unit)

• Resource loss worsens traumatic stress– Psycho-social resources (e.g., friends)

• Kids can do a little better here—from research perspective• Older adults can be vulnerable to effects of displacement

– Physical resources/access• Extortion (“Cuotas”)• Example: IMSS

Alim et al., 2008; Rivera et al., 2008; Hobfall et al., 2009; Wyshak, 1994; Fozdar, 2009

Page 64: Ongoing Traumatic Stress (OTS) and Post-Traumatic Stress Disorder (PTSD): The impact of cartel related violence on the U.S./México border. Thom Taylor

Social Support• Strongest buffer to Post-Traumatic Stress

– Applies to retrospective reports– Potentially more accessible when exposure is acute

vs. ongoing• May be more nuanced in Ongoing violence

– Supporting others in uncontrollable and unpredictable ongoing stressors may be difficult

– Larger families may have resources spread across many individuals

• Provider vs. receiver?

Community Support Opportunity

• Regional attention to traumatic stress– A need (Cartel violence, Veterans of OEF/OIF)– An opportunity to be a “Star” community for helping

those affected by traumatic stress• Psychological/Psychiatry is important, but not the

only answer:– Limit mental health stigma and shame – Promote autonomy: “feeling in control”– Potential nuances of exposure therapy

Creative Community Support• Promote predictability

– May be limited in Cd. Juárez (ideas?)– El Paso/U.S. side of the border

• Educate on traumatic stress and the range of people affected-builds empathy

• Streamline policies/systems to accommodate range of victims’ needs

• Limit daily stressors: “the daily grind”– Wears down mental resources– Unprepared when crisis occurs

Sutton, 2010; Hobfoll et al., 2007; Wei et al., 2010; Bryan, 2010

Preventing “low power”• Address daily stressors of patients/clients/staff

– Is a action/policy a barrier, a benefit, or both for the• Patient/client?• Staff?

– Can the action/policy be adapted to reduce “the daily grind?”– Can benefit not just the individual patient/client, but also the

system and staff• Support the supporters

– Remember, there is a hierarchy many systems– “____________ flows downhill.”– You fill in the blank (can be positive or negative word)

• After presentation, I am interested in hearing your perspectives on how to prevent “low power.”

Page 76: Ongoing Traumatic Stress (OTS) and Post-Traumatic Stress Disorder (PTSD): The impact of cartel related violence on the U.S./México border. Thom Taylor

Focus on “Small Wins”• Big changes are rare and when they do

occur, there is sometimes a backlash• Find ways to make “small wins”

– Recognize small wins as wins none-the-less– Reinforces future action that can promote

future “small wins”• Promotes self-efficacy• May promote community efficacy

– Small wins add up.

Bryan, 2010

Limitations and Strengths of Present Study

• Limitations– Threshold for impairment in PCLS may be different for

this group• Sensitivity and specificity • Need for focus on psycho-social impairment criterion

– Convenience/snowball sampling may limit generalizability of findings

– Low statistical power due to large inter-individual variability

• Strengths– Daily level longitudinal assessment; not feasible in many

cases– Professionally back-translated measures

Page 78: Ongoing Traumatic Stress (OTS) and Post-Traumatic Stress Disorder (PTSD): The impact of cartel related violence on the U.S./México border. Thom Taylor

Conclusions• Moderate to high levels of ongoing traumatic

stress a likely reality for many with close ties to Cd. Juárez

• Risk factors and buffers commonly associated with PTSD nuanced in Ongoing (Daily) Traumatic Stress

• Community can do a lot to indirectly help those affected by trauma– “Small Wins”– Creative opportunities for community support?

The Future of Cartels• When substance use revenues change, cartels may

not disappear or even become weaker (VERY ADAPTIVE)– Example: 1920s-1930s Chicago– U.S. Gangs

• May move in to other activities that traumatize the population– Human/body trafficking (sex, labor, organs)– Consideration of (illegal) supply chains– Partnerships with other dangerous entities

• We need to consider the future of cartels to prevent future traumatization of our loved ones and friends.

Time permitting, I would like

• Questions• A discussion of problem focused coping from

your eyes?• To hear about possible “Small wins” in

change/adaptation of activities and policies you think could help your organization to help those affected by trauma?
