This article proposes
a
framework
for
representing personality constructs
at
four levels of abstraction. The total aggregation model is the composite formed
by the sum of scores on all items in a scale. The partial aggregation model
treats separate dimensions
of a
personality construct
as
indicators
of a
single
latent variable, with each dimension being an aggregation of items. The partial
disaggregation m odel represents each dimension as a separate latent variable,
either freely correlated with
the
other dimensions
or
loading
on one or
more
than one higher order factor; the measures of the dimensions are multiple
indicators formed as aggregates of subsets of items. The total disaggregation
model also represents each dimension
as a
separate latent variable
but,
unlike
the partial disaggregation model, uses each item in the scale as an indicator of
its respective factor. Illustrations
of the
models
are
provided
on the
State
Self-Esteem Scale—including tests
of
psychometric properties, invariance,
and
generalizability.
It is often assumed in personality research that a single scale ought to
measure a single construct
(Briggs & Cheek, 1986, p. 109). Indeed, such a
point of view is at the heart of what is meant by
construct validity
(e.g.,
Campbell & Fiske, 1959; Cook & Campbell, 1979). Measures of a construct
are valid to the extent that they measure what they are supposed to measure.
As simple and reasonable as these assertions appear to be, it has proved
difficult to reach a consensus on the criteria for representing personality

constructs. Many personality constructs were originally conceived as uni-
dimensional but over time have come to reveal multifaceted components.
For example, self-monitoring was initially conceived along a continuum
from low to high (e.g ., Snyder, 1974,1979) but later showed multiple factors
underlying Snyder's 25-item scale (e.g., Briggs & Cheek, 1988; Briggs,
Cheek, & Buss, 1980; Gabrenya & Arkin, 1980; Hoyle & Lennox, 1991;
Lennox, 1988; Lennox & Wolfe, 1984; Miller & Thayer, 1989; cf. Snyder &
Gangestad, 1986). Similarly, self-esteem was conceived early on as a uni-
dimensional construct measured with 10 items (e.g., Rosenberg, 1965,
1979).
But recently, self-esteem or, more broadly, the self-concept has been
regarded as a multifaceted construct (e.g., Fleming & Courtney, 1984;
Marsh, Byrne, & Shavelson, 1988; Marsh & Shavelson, 1985; Shavelson &
Bolus, 1982; Shavelson & Marsh, 1986; for an early statement, see Gecas,
1971). One version of the Self Description Questionnaire, for example, has
seven dimensions and uses 66 items (e.g., Marsh, 1988).
Considerable uncertainty and disagreement exist about how to repre-
sent and measure many personality constructs. Part of the problem lies
with differences in interpretation between single-faceted and multifac-
eted conceptualizations. In a related vein, researchers often address a
personality construct from the perspective of only one of several possible
levels of abstraction but fail to point out the implications of doing so. For
instance, concepts can be represented on a single dimension on which
multiple dimensions have been collapsed or in some way aggregated;
likewise, items designed to measure a personality concept can be aggre-
gated or disaggregated, depending on one's purposes. As a consequence,
at least four possibilities exist when aggregation or disaggregation is
crossed with items and dimensions.
Carver (1989) offered two broad arguments in favor of multifaceted
constructs in personality research. First, Carver maintained that "individual
facets of a construct should sometimes predict dependent variables better
than should the broader construct (i.e., the overall index)" (p . 579). Indeed,
depending on the context, it is possible for some dimensions to positively
predict a criterion, others to be unrelated, and still others to be negatively
related. Lumping together items across dimensions in an index could mis-
leadingly yield a weighted average and obscure the differential contributions
of the dimensions. In support of this conclusion, Briggs and Cheek (1986)
presented findings showing that the total score and scores for the individual
dimensions of self-monitoring correlate at different levels and in different
patterns across various criteria. The second point made by Carver (1989) in
support of multifaceted constructs is based on the observation that the whole
may be greater than the sum of its parts. By this, Carver meant that "some
multifaceted constructs seem to be based on the assumption that the several
components interact with each other to produce the outcome effect of inter-
est" (p. 582). Obviously, summing items across subdimensions of a scale
would fail to account for such a possibility.

MULTIFACETED
PERSONALITY CONSTRUCTS 3 7
Building on Carver's (1989) insights, Hull, Lehn, and Tedlie (1991)
proposed
an
approach
for
testing multifaceted personality constructs based
on structural equation modeling with latent variables (see also Marsh &
Hocevar, 1985). Hull et al. proposed two general models. One, a measure-
ment model, consists
of
testing
the
hypothesis that
an
underlying latent
variable accounts for variation among measures of subcomponents of a
personality scale. Hull
et al.
illustrated this model
on
measures
of
hardiness
and found that a single latent variable accounted for significant amounts of
variation in measures of five subdimensions: alienation from work, alien-
ation from self, security, powerlessness, and external locus of control. Hull
et al.'s second contribution was to model the effects of latent personality
constructs
on
criteria treated
as a
dependent variable.
The
advantages
of
this
approach over regression analysis
are
that measurement error
in the
predic-
tors
is
taken into account explicitly,
and the
effects
of the
latent personality
construct can be partitioned into a general effect shared by the sub-
dimensions and any additional specific effect due to one or more than one
subdimension. Hull
et al.
applied their predictive model
to two
contexts—
the effect of hardiness on depression and the effect of self-punitive attitudes
(i.e., self-criticism, high standards, overgeneralization)
on
depression.
One of our goals in the present article is to introduce a comprehensive
framework
for
representing personality constructs that brings issues
of con-
struct validity and levels of analysis into clearer focus. The framework
applies to personality concepts in which measures are related in additive,
linear ways
to one or
more than
one
dimension.
In the
Discussion section,
we
cover important classes of personality concepts in which the framework does
not apply. A second purpose is to illustrate models implied by the framework
on measures of the State Self-Esteem Scale (SSES), a scale recently intro-
duced by Heatherton and Polivy (1991). Heatherton and Polivy used classic
procedures (e.g., exploratory factor analysis; correlations)
to
analyze
the
psychometric properties
of
measures
and
placed emphasis
on the
total scale
as well as three dimensions: performance, social, and appearance. Based on
prior research, SSES items were chosen to measure these dimensions, and
the results of an exploratory factor analysis supported the scale and its
subdimensions (Heatherton
&
Polivy, 1991).
Our aim is to
develop
a
more
refined representation of the SSES based on alternative levels of abstraction
organized hierarchically and to test the alternatives. We discuss the relation
of our framework to previous approaches on which it builds.

up of the sum of items hypothesized to measure it. Following the convention
established in the literature, theoretical or latent variables are drawn as
circles or ellipses in Figure 1, and measurements are depicted as boxes. For
the total aggregation model, the relation between the SSES as a latent
variable and its measurement as the sum of items from the scale is taken to
reflect a 1:1 correspondence. No degree of correspondence is modeled, and
no attempt is made to account for m easurement error. Although a measure of
reliability might be computed based on the associations among measure-
ments (e.g., Cronbach alpha) and then used to correct for attentuation in
predictions of a criterion, no formal representation is provided of the mea-
surement properties of the scale, such as is possible with the other cases
illustrated in Figure 1 and as discussed here . The total aggregation model is
consistent with current conceptualizations of self-esteem as a "hypothetical
construct that is quantified ... as the sum of evaluations across salient
attributes of on e's self or personality" (Blascovich & Tomaka, 1991, p . 115).
Note that the total aggregation model constitutes an aggregation of both
dimensions and items. To examine the case in which dimensions are aggre-
gated and items disaggregated, a single-factor model can be investigated in
which all items load on the factor.
The main advantages of the total aggregation model are its simplicity and
ability to capture the essence of the underlying meaning of a personality
concept. However, the advantages accrue only to the extent that the mea-
sures share sufficient common variance. To the degree that measures share
common variance, the summation of items tends to smooth out random error
and permit the total aggregation model to function as a useful representation.
The primary disadvantage of the total aggregation model is that it fails to
represent the unique properties of subdimensions, if any, and obscures both
the differential dependence and the effects of subdimensions on other con-
structs of theoretical interest. The total aggregation model has its place in
molar assessments of behavior, but, for more fine-grained analyses, less
global representations are needed. The remaining models to be introduced
explore the representation of the aggregation and disaggregation of items
under the condition of when dimensions are hypothesized (i.e., when dimen-
sions are disaggregated).
The partial aggregation model shown in Figure 1 constitutes a more
molecular representation of a latent personality construct, yet it retains
the idea of a single underlying factor. Two cases are of interest. In the
first case, the dimensions of the construct are organized hierarchically as
indicators of an underlying factor. Three dimensions are shown, corre-
sponding to those proposed by Heathcrton and Polivy (1991) for the
SSES,
but it should be pointed out that other personality constructs with
more than three dimensions can be accommodated by such an approach,
depending on the theory at hand. For the Self-Description Questionnaire
(SDQ), for example, one might have as many as 12 dimensions (e.g.,
Marsh, Barnes, & Hocevar, 1985).

To test the hierarchical representation of the partial aggregation model as
a null hypothesis, a confirmatory factor analysis (CFA) can be performed in
which composites of items for each dimension are treated as indicators of a
single factor. A failure to reject this model based on standard statistical
criteria suggests that each of the multiple indicators measures a single
underlying construct. The construct can then function as a predictor or
predicted variable in a structural equation model (SEM) while taking into
account measurement error in the measures of the construct. Hull et al.
(1991) advocated this approach in their study of hardiness, and Bagozzi and
Heatherton (1993) utilized this form of the partial aggregation model to
examine convergent and discriminant validity of measures of the SSES and
the Multiple Affect Adjective Check List.
If the partial aggregation model is rejected on the basis of standard
statistical criteria, then one of two conclusions can be drawn. Either two or
more factors underly the latent personality concept, or the measures of the
hypothesized dimensions of the latent personality construct are highly falli-
ble. The former possibility can be addressed by use of the partial disaggre-
gation model, which is discussed shortly. The latter possibility, of course,
requires that better measures be obtained.
A second kind of partial aggregation is possible and is labeled the discrete
components case in Figure 1. Here the dimensions of the personality con-
struct are not formally modeled as indicators of it but rather are treated as
separate subscales and are considered only loosely tied to the overall con-
struct. Two approaches might be taken with discrete components in the sense
shown in Figure lb. In the first, items particular to each component are
summed to form separate composites. This might be based on conceptual
criteria of shared meaning of items within components and of distinct mean-
ing of items across components, as well as empirical criteria derived ex post
facto from a factor analysis. Researchers claiming that the Self-Monitoring
Scale (SMS) is made up of acting, extraversion, and other-directed sub-
dimensions have basically taken this approach (e.g., Briggs & Cheek, 1986).
Likewise, Carver's (1989) treatment of multifaceted personality constructs
seems to rely on this interpretation, and Heatherton and Polivy's (1991) test
of the SSES rests on a discrete-components understanding. This discrete-
components approach is analogous to the total aggregation approach in that
each component is treated as a separate aggregate made up of the sum of
scores to items reflecting that component.
The other way to address discrete components is to model the relation
between each component and its measures with a separate CFA model. Each
latent variable is treated as a composite variable and the measures as indica-
tors.
The outcomes and conclusions already mentioned for the CFA of the
hierarchical organization of components also apply to each component so
treated in the discrete-components case.
The principal advantages of the hierarchical organization of components
in the partial aggregation model are that separate parameter estimates are

derived representing the degree of correspondence between the latent per-
sonality construct and its subdimensions (i.e., the Xs in Figure lb ) and at the
same time estimates of m easurement error are provided (i.e., the 6s in Figure
lb) . This permits an assessment of the reliability of measures and the oppor-
tunity to correct for unreliability in predictions, as already noted. The main
disadvantage of this model is that the unique dimensions of the overall
personality construct, if any, are obscured.
A more fine-grained representation of multifaceted personality constructs
can be performed by use of the partial disaggrega tion model (see Figure 1 ).
Here each component or dimension is represented as a separate latent vari-
able indicated by composites of subscales. The first-order partial disaggrega-
tion model estimates the degree of correspondence between each component
and its respective measures, as well as the respective error variances. More-
over, separate estimates are provided for the correlations among dimensions,
which can be used to assess the degree of discrimination between dimen-
sions.
These correlations are corrected for attentuation as a consequence of
standard estimation procedures. We have shown two measures per dimension
in the partial disaggregation model—each formed as composites of items
from the subscales—but it should be emphasized that more measures can be
specified, depending on the number of items available per dimension. Guide-
lines for forming composites are discussed in the Method section. The
first-order partial disaggregation model assumes that the dimensions are
distinct—that is, the measures of the separate dimensions are presumed to
achieve discriminant validity between dimensions. The degree of discrimi-
nant validity is inversely proportional to the magnitude of the correlations
among the first-order factors (shown as (j>s in Figure lc ) . Strong discrim inant
validity will be achieved when the 4>s are nonsignificant or small; weak
discriminant validity will be achieved when the
s
are high but less than 1.00
by an amount greater than twice the standard error (SE) of the estim ate of .
Lack of discrim ination in a strict statistical sense occurs when the 4>s are
within 2 SE of 1.00.
The second-order partial disaggregation model treats the components as
first-order factors and introduces a second-order factor explaining variation
in the first-order factors. The second-order factor can be thought of as an
abstract representation of the overall personality construct. The second-
order model partitions variation in measures into three components—ran-
dom error, measure specificity, and common variance. The first-order model
only partitions variation into that attributable to error and the components;
random error is confounded with measure specificity (Marsh & Hocevar,
1988).
One interpretation of the second-order partial disaggregation model is the
following. To the extent that the first-order factors include common vari-
ance, the second-order factor captures the shared variance across factors. A
single second-order factor suggests that the dimensions measure the same
hierarchical concept, except for random error and measure specificity. It

should be noted that more than one higher order factor might be appropriate,
depending on the theoretical context and personality concept.
The principal advantage of the first-order partial disaggregation model is
that it is possible to specify and test for the existence of multiple dimensions
of a personality construct. Useful diagnostics and information are provided
on properties of the dimensions and their measures. One of the first studies
to use a first-order partial disaggregation model to test a theory of personal-
ity was Marsh and Hocevar's (1985) investigation of the SDQ. Hull et al.
(1991) examined a somewhat similar model for self-punitive attitudes as part
of a predictive model of depression. Because structural equation methods are
based on full-information procedures, a measurement model embedded
within a predictive model might differ from a measurement model treated in
isolation, such as the partial disaggregation model.
The main advantage of the second-order, partial disaggregation model is
that hypotheses can be tested about the hierarchical structure of a personality
construct (e.g., Marsh & Hocevar, 1985). In addition, both versions of the
partial disaggregation model permit interesting inquires into discriminant
validity among dimensions of a personality construct. The first-order model
provides estimates of the degree of association among the dimensions with
the measures corrected for attentuation. Discriminant validity occurs to the
extent that the factors are distinct. However, it should be remembered that
random error and measure specificity are confounded. The second-order
model estimates measure specificity for the indicators of each dimension.
Yet a trade-off can be seen through the two models. Discriminant validity in
a strong sense will be achieved when dimensions are uncorrelated or w eakly
correlated . Here a higher order model is not meaningful because the dimen-
sions do not share common variance. Discriminant validity will be achieved
in a weak sense when they are highly correlated, but significantly less than
1.00. But to the extent that a single second-order factor represents the data,
discriminant validity among dimensions may be less defensible, and the
dimensions should be interpreted as subcomponents of a higher order organ-
izing concept. Of course, depending on the theory, it is possible to have
multiple higher order factors and achieve discriminant validity across these.
Conclusions about discriminant validity may be ambiguous when drawing
the line between "high" and "moderate" correlations.
The final model we consider is the total
disaggregation
model (see Figure
1).
In this model, each dimension of a multifaceted construct is modeled as
a distinct latent variable, as with the partial disaggregation model, but,
unlike the partial disaggregation model, which uses composites based on
subscales as indicators of the latent factors, each individual item from the
personality scale is used to operationalize its respective hypothesized dimen-
sion. This yields what might be termed an "atomistic" level of analysis to
contrast it with the "molar" total aggregation model and the more "molecu-
lar" partial aggregation and partial disaggregation models. In principal, the
total disaggregation model provides the most detailed level of analysis of a

personality construct because psychometric properties are provided for each
individual item. In practice, however, the total disaggregation model can be
unwieldy because of likely high levels of random error in typical items and
the many parameters that must be estimated. As the number of items per
factor increases and sample sizes increase, it is likely that many total disag-
gregation models may fail to fit the data satisfactorily. As a consequence, the
total disaggregation model is likely to be applied successfully, if at all, only
when about four or five measures per factor or fewer are used. Nevertheless,
even with more than five measures per factor, the total disaggregation model
can
be

effects.

tion model applied
to the SMS.

fit
very well, however,
on the basis of contemporary goodness-of-fit tests. Under some conditions,
correlated uniquenesses may be used to investigate method biases and other
sources of model misspecification, but this should be done cautiously and
should be guided by theoretical considerations (e.g., Marsh, 1989). It is also
possible that method factors can be introduced corresponding to item rever-
sals or other systematic format or wording patterns.
THE PRESENT STUDY
As an illustration of the general framework for representing personality
constructs,
the
hierarchical organization
of
responses
to the
SSES
was
exam-
ined in two samples. The first objective was to investigate the reasonable-
ness of the part ia l aggregat ion, part ia l disaggregat ion, and total
disaggregation models for the data at hand. We focused on goodness-of-fit
tests,
reliabilities
of
measures, discrimination among components,
and
parti-
tioning of variance into useful components. Second, an indication of the
generalizability of the partial aggregation and partial disaggregation models
for the SSES was explored. This was done by examining the replicability of
the models and key parameters across the samples. Last, a comparison was
made by gender to see if the structure of the SSES is equally applicable to
women and men.

SSES
The SSES is a 20-item scale developed by Heatherton and Polivy (1991) and
based on items from the Fleming and Courtney (1984) and Pliner, Chaiken,
and Flett (1990) modifications of the Janis-Field Feelings of Inadequacy
Scale (Janis & Field, 1959). Items were selected to reflect acute as opposed
to typical levels of self-esteem and to include performance, social, and
appearance subdimensions, which a subsequent factor analysis supported
(Heatherton & Polivy, 1991). To further emphasize current feelings of self-
esteem, the following instructions were used:
This is a questionnaire designed to measure what you are thinking at
this moment. There is, of course, no right answer for any statement.
The best answer is what you feel is true of yourself at this moment. Be
sure to answer all of the items, even if you are not certain of the best
answer. Again, answer these questions as they are true for you RIGHT
NOW.
Responses are recorded on a 5-point scale with points labeled not at all (1),
a little bit
(2),
somewhat
(3),
very much
(4), and
extremely
(5). The 20-item
SSES can be found in the Appendix.
Procedure
Subjects in Sample 1 completed the SSES and several other scales not
relevant to the current study. Subjects responded to the items while seated in
a quiet room and were tested individually. Subjects in Sample 2 completed
the SSES and other scales not pertinent to the present study and did so in a
single mass-testing session.
Statistical
Criteria
In this article, the models examined can be fit and the hypotheses can be
tested using structural equations methods (Bentler, 1989; Bollen, 1989;
Joreskog & Sorbom, 1989). These procedures permit the representation of
latent variables corresponding to the overall SSES, as well as its dimensions
or components, and facilitate the investigation of the hierarchical arrange-
ments presented in Figure 1.

Assessment of overall model fit. The degree of correspondence be-
tween any particular model and the data can be assessed with the use of
several measures. The chi-square goodness-of-fit test indicates the discrep-
ancy between a hypothesized model and data. Significant values of the
chi-square goodness-of-fit test indicate that the data and model deviate in a
fundamental way and that the model should be rejected. A nonsignificant
chi-square goodness-of-fit test with
p
a .05, say (e.g., Bentler, 1989), sug-
gests that a model is a reasonable representation of the data.
Because the chi-square test is sensitive to sample size and can lead to
a rejection of a model differing in a trivial way from the data for large
sample sizes—and conversely can result in the acceptance of a model
with important differences from the data for small sample sizes—it is
prudent also to examine other measures of fit. McDonald and Marsh
(1990) proposed the relative noncentrality index (RNI) in this regard (see
also the comparative fit index proposed by Bentler, 1990, which is similar
to the RNI). The RNI is a refinement of the normed fit index (Bentler &
Bo nett, 1980), which measures the amount of variance accounted for by a
model in a practical sense. Like the normed fit index, the RNI takes on
values from 0 to 1, inclusive, but is not a statistic because its sampling
distribution is unknown. Unlike the normed fit index, the RNI corrects for
small sample biases and has been shown to perform better than many
other indices (e.g., Bentler, 1990; McDonald & Marsh, 1990). Following
the rule-of-thumb suggested by Bentler and Bonett (1980), RNI values
grea ter than or equal to about .90 are taken to indicate a satisfactory fit
from a practical standpoint.
Tests of hypotheses. Chi-square difference tests are used to test
hypotheses. One set of hypotheses concerns the equality of factor loadings
and of error variances for measures of a single factor, such as shown in
Figure lb for the partial aggregation model. In general, with two measures
of a factor, the model will be underidentified (the variance-covariance
matrix for measures is not sufficient to provide enough information to
estimate parameters); with three measures, the model is exactly identified;
with four or more measures, it is overidentified. An exactly identified
model provides enough information to estimate all parameters, but, be-
cause df = 0 for this model, the chi-square test indicates a perfect fit. To
test how well the single-factor model with three measures fits the data
versus the most general alternative—that the variance-covariance matrix
is any positive definite matrix—we can constrain all three factor loadings
(or selected subsets of two) to be equal. This yields a chi square with 2 df
(1 d/will result for the case in which a pair of loadings is constrained to
be equal). The chi square in this case gives a test of whether the three
components of the SSES each load on a single factor and equally reflect
that factor.

Further, one might want to test whether the error variances are equal for
the single-factor model in Figure l b . This can be accomplished by constrain-
ing both the factor loadings and the error variances to be equal and compar-
ing the chi square for this model to the one in which only the factor loadings
are constrained to be equal. The difference in chi-square values with degrees
of freedom equal to the difference in degrees of freedom for the two mod-
els—in this case,
df =
4 - 2 = 2—gives a test of the reasonableness of
assuming equal error variances. Note further that this hypotheses and the
ones considered later must be performed on the variance-covariance matrix
(e.g., Cudeck, 1989). For multiple-factor models with two or more measures
per factor, such as presented in Figures lc and Id, the models will be
overidentified.
Another set of hypotheses to address is whether the SSES—as reflected in
any or all levels depicted in Figure 1—generalizes to other samples. We can
test whether the same factor structure and parameters for a particular model
apply to two or more samples. In other words, we are interested in the degree
of replicability of the SSES. One way to do this is to compare models with
identical structures—in which key parameters are fixed to be equal across
samples—to models with no equality constraints. This can be done in a
sequential manner. For example, the model in Figure lb might begin with a
test of whether the Xs are invariant across samples; next, one could test
whether both the Xs and 0ss are invariant. Likewise, for the models in Figure
lc , one might test the following: for the first-order, three-factor model,
whether the Xs are invariant, then the Xs and 6as, and finally the Xs, 6&s, and
s assesses whether the SSES compo-
nents covary equally. The additional test of invariance in vs and in ips
investigates whether the sources of common and specific variance, re-
spectively, are equal across samples. The aforementioned sequences of
hypotheses constitute increasingly demanding tests of the generalizabil-
ity of the SSES. These tests should be performed only after it is demon-
strated that the variance-covariance matrices differ across samples and
that the same factors underlie the data (e.g., Cole & Maxwell, 1985;
Joreskog & Sorbom, 1989).
The final tests of hypotheses concern the appropriateness of the SSES for
men and women. The models for the representation of the SSES shown in
Figure 1 can be compared for men and women, and sequences of hypotheses
can be tested for key param eters, as already described for the tests performed
on different samples (cf. Byrne & Shavelson, 1987).

Examination of parameters.
Further insights into the fits of models
and tests of hypotheses can be obtained by inspection of parameter esti-
mates.
Reliabilities can be computed for measures of the overall SSES and
for the individual components by use of the following formula:
in which
X\
refers to the ith factor loading on the factor corresponding to
either the overall SSES in the partial aggregation model (i.e., 2=) or the
individual components for the first-order partial disaggregation model (i.e.,
=p,
| s ,
£A),
and 6ei stands for the error variances of the measures of compo-
nents in either the partial aggregation model (i.e., Zpj, Zsk, Zai) or the partial
disaggregation model (i.e., 2p
m
, 2p
n
, 2s
0
,Zs
p
, 2a
q
, Za
r
). An indication of the
degree of discrimination among the components of the SSES can be garnered
by inspection of the correlations among factors (i.e., the s) in the first-
order, three-factor partial disaggregation model. Information on the parti-
tioning of variance in measures of the SSES components can be obtained by
looking at the parameter estimates for the second-order, three-factor partial
disaggregation model. Three types of variance are of interest: random error,
measure specificity (i.e., variance shared by measures of the same factor),
and common variance (i.e., variance shared by all measures).
Specification
of
Measures
for the Partial Disaggregation
Model
The specification of operationalizations for the total aggregation, partial
aggregation, and total disaggregation models shown in Figure 1 is straight-
forward. For the total aggregation model, the SSES is operationalized as the
sum of items in the total scale. For the partial aggregation model shown in
Figure 1, each dimension is operationalized as the sum of items hypothesized
to measure that dimension.
For the total disaggregation model, each item is treated as a measure of its
respective SSES dimension. In practice, particularly with large numbers of
items, the total disaggregation model may be impractical in the sense that the
pattern of responses to items will deviate significantly from the hypothesized
structure, and correlated residuals may be needed to achieve satisfactory fits
for the model. However, correlated residuals are frequently difficult to
interpret, too many distort the meaning of the hypothesized structure, and, in
any case, one should have a theoretical rationale to permit an interpretation.
In our experience, when more than about five items per factor are treated as
individual measures of factors in a multifactor CFA, it is difficult to achieve
a satisfactorily fitting model that is interpretable in an unambiguous sense.

Nevertheless,
as
mentioned earlier,
the
total disaggregation model
has its
place
and can be
useful
in
item analyses
and
investigation
of
method effects
due
to
item reversals
or
other systematic biases.
Several alternatives
can be
identified
for the
operationalization
of a
partial disaggregation model. When
the
number
of
items
per
dimension
is
relatively small—say, as many as five to seven items, it seems prudent to
form two composites for each dimension in which each composite is a
sum of items. In fact, this was the strategy chosen for the partial d isaggre-
gation model
of the
SSES examined
in
this study. When nine
or
more
items exist
per
dimension
in a
scale,
it is
feasible
to
form three
or
more
composites
as
indicators
for
each dimension.
For
their analysis
of the
SDQ, Marsh
and
Hocevar (1985) used four com posite indicators
for
each
of seven dimensions.

Total aggregation model. When

items, the
Cronbach alpha reliabilities
are .91 for

and

As a

it is

to

eter estimates, based on the correlation matrix as input, are presented for
ease of interpretation, in which it can be seen that factor loadings are high
and error variances are low for Sample 1. Using the formula for reliability
presented in the Method section, we find that the SSES is reliable in Sample
1 (p = .79). Model M3 hypothesizes that the factor loadings for the three
SSES dimensions are equal. For this and each subsequent hypothesis, the
covariance matrix is used as input to LISREL (Cudeck, 1989). Although the
chi-square test is significant for M3, X
2
(2, N = 102) = 7.72, p - .02, the RNI
of .93 suggests that the model fits satisfactorily as a practical matter. Never-
theless, a comparison of models M3 and M2 shows that one must reject the
hypothesis that the factor loadings are equal, x d(2) = 7.72,
p <
.02. Model
M4 introduces the additional restriction that the error variances of the mea-
sures of performance, social, and appearance are equal. Although the chi-
square value for M4 is significant, x (4, N = 102) = 12.15, p ~ .02, the model
fits w ell in a practical sense (RNI = .90). A comparison of M4 and M3 reveals
that we cannot reject the hypothesis that the error variances are equal, x d(2)
= 4.43, /?>.12.
The findings for Sample 1 so far suggest that the partial disaggregation
model fits the data well but that the factor loadings, although high and
significant in each case, are not equal. Actually, the test of equality of factor
loadings (and error variances) is a demanding one in the sense that tau-
equivalency or parallel forms are not necessary in order to achieve meaning-
ful scales and that the congeneric test, implied by the model in which no
equality restrictions are placed on factor loadings and error variances, pro-
vides sufficient information on the properties of a scale . Occasionally, a
researcher may, given a rejection of the hypothesis of equal factor loadings
(and/or error variances), want to test whether subsets of loadings (and/or
error variances) are equal. This was done for illustrative purposes, and the
results are summarized under models Ms and M6 in Table 1. Model Ms,
which hypothesizes that the factor loadings for performance and social are
equal, fits well, x
2
( l , N = 102) = .07, p ~ .78, RNI = 1.00. A comparison of
M5 and M2 shows that we cannot reject the hypothesis of equal factor
loadings, x
2
d(l) = 07, p > .78. Model M6 also fits well, x
2
(2 , N
=
102) = .53 ,
p .77, RNI = 1.00. A comparison of M6 and Ms indicates that we cannot
reject the hypothesis of equal error variances, x
2
d( l) = .46, p > .50.
Looking next at the findings for Sample 2, we see that factor loadings
under the baseline model are high and error variances are low. The reliability
of the m easures for the SSES is p = .81. The results for M3 point to a
satisfactory fit, x
2
(2, N= 428) = 9.67, p - .01 , RNI = .98, but the hypothesis
of equal factor loadings must be rejected, x d(2) = 9.67, p < .01 . Likewise,
although M4 fits reasonably well, x (4, N= 428) = 25.24,p - .00, RNI = .95 ,
we must reject the hypothesis of equal error variances, x
2
d(2) = 15.57, p <
.001. The test of equal factor loadings for performance and social reveals
that we cannot reject this hypothesis, x

Partial disaggregation model. The test of the equality of variance-
covariance matrices for Samples 1 and 2 showed that x (21, Ni = 102, N2 =
428) = 26.06, p - .20. Hence, we cannot reject the hypothesis that the
measures are equivalent between the two samples.
In sum, the variance-covariance matrices among measures of the SSES
are quite similar across the samples when we examine (a) measures of the
components treated as separate aggregates but loading on a single factor (the
partial aggregation model) and (b) measures of the components treated as
subaggregates loading on three factors (the partial disaggregation model). As
a consequence, it is not meaningful to test for differences in factor structure
and parameter estimates across the samples. It should be noted that the
analyses to be reported for gender differences show that the variance-covar-
iance matrices do in fact differ between men and women in Sample 2, and we
are thus able to explore more fully hypotheses related to equality of factor
structures for the partial aggregation and partial disaggregation models.
Because the results for the total disaggregation model revealed that the
single- and three-factor models fit poorly, no tests of generalizability were
performed on these models.
Tests
of Generality of SSES cross Gender
Examination of basic models for organization of the SSES. Table
5 summarizes the findings for the partial aggregation model for women and
men from Sample 2 (Sample 1 is too small to permit a comparison of men
and women). Looking first at the results for women, we see that factor
loadings are high and error variances are low. The reliability of measures is
p = .80. All models fit well as a practical matter, as shown by the RNIs.
However, tests of equality of parameters show that neither factor loadings,
X
2
d(2) = 11.11, p> .001, nor error variances, x
2
d(2) = 9.72, p
<
.01, are equal
for this single-factor model. Further, tests for the subset of factor loadings
and error variances corresponding to performance and social indicate that
neither pair is equal, x
2
d(l) = 6.28,
p <
.01, and X
2
d(l) = 9.53,
p <
.001,
respectively. Looking next at the findings for men, we see that factor load-
ings are high and error variances are low. The reliability of measures is p =
.84.
All models fit well on the basis of RNIs, and, indeed, three of four fit
well on the basis of the chi-square test. Likewise, one cannot reject the
hypothesis of equal factor loadings, x
2
d(2) = 3.34, p > .19. The hypothesis of
equal error variances, however, must be rejected, x d(2) = 9.24,p

for the tests of subsets of factor loadings and error variances, one cannot

dimensions, x

Table 6 presents the results for the partial disaggregation model for the
first-order, three-factor case. The model fits the data well for women and
men, based on the values for the RNIs. For women and m en, factor loadings
are high and error variances are low. The reliabilities for m easures of perfor-
mance, social, and appearance are, respectively, p
P
= .80, p
s
= .84, and p
a
=
.83 for women and p
p
= .89, p
s
= .84, and p
a
= ,84 for men. The correlations
among the performance, social, and appearance factors are high and yet are
significantly less than 1.00. Table 7 shows the findings for the partial disag-
gregation model for the second-order, three-factor case. The model fits w ell
in both samples, factor loadings are high, error variances and specific vari-
ance are generally low, and common variance ranges from moderate to high
for the most part.
Tests of equ ality of models across wom en and men.
For the par-
tial aggregation m odel, the test of the equality of variance-covariance matri-
ces for women and men revealed that x (6, JVi = 284,
N2
= 144) = 8.09,
p -
.23. Thus, we cannot reject the hypothesis that the measures are equivalent
for women and men.
Table 8 summarizes the findings for the tests of equality of the partial
disaggregation model (first-order, three-factor case) for women and men.
The test of the equality of variance-covariance matrices shows that x (21,
Ni =
284, JV2 = 144) = 34.03,
p
~ .03, and therefore we must reject the
hypothesis that the measures are equivalent (see M i in Table 8) . The second
row in Table 8 reveals that the factor pattern is the same for women and
men—that is, the same three factors exist. Next it can be seen that the
hypothesis of equal factor loadings cannot be rejected, x
2
d(6) = 8.62, p > .21
(see the third row in Table 8). Likewise, we cannot reject the hypothesis that
the error variances are equal, x
2
d(6) = 12.62, p > .05 . Last, the hypothesis of
equal covariances among the factors of performance, social, and appearance
cannot be rejected, x
2
d(3) = 6.40,
p >
.09.
Table 9 presents the results for the tests of equality of the partial disaggre-
gation model (second-order, three-factor case) for women and men. Unlike
the first-order model in which the disturbance terms confound random error
with measure specificity, these analyses provide separate estimates of ran-
dom error and measure specificity. The tests of equal covariance matrices
and factor patterns are the same as for the first-order model. The test of equal
factor loadings shows that we cannot reject this hypothesis, x
2
d(3) = 5.47, p
> .15 (see the third row in Table 9). The hypothesis of equal error variances
for m easures, however, must be rejected, x d(6) = 14.32,
p <
.03. We cannot
reject the hypothesis of equal error variances for the first-order factors—

DISCUSSION
S S E S
Overall, the findings show that the SSES can be represented in a psychomet-
rically sound way through both the partial aggregation model (treated as a
hierarchical organization of components under a single SSES latent variable)
and the partial disaggregation model (treated as either a first-order or sec-
ond-order model of three latent variables corresponding to the dimensions of
the SSES). The total disaggregation model of the SSES also showed that the
scale can be represented as three factors corresponding to performance,
social, and appearance dimensions. However, a satisfactory fit was achieved
only after the introduction of method factors. These results complement the
findings of Heatherton and Polivy (1991), who confined analyses to the total
aggregation model and the partial aggregation model, in which the latter
dealt with each dimension of the SSES as a discrete component measured
without error.
The partial aggregation model provided a cogent representation of the
SSES at a high level of abstraction. In this sense, it supports the interpreta-
tion and use of the SSES as a multifaceted composite. Unlike the traditional
total score approach, which fails both to provide a precise representation of
the SSES as a latent construct and to model measurement error explicitly, the
partial aggregation model captures the hierarchical organization of the SSES
as a singular, general factor with three dimensions and supplies information
on the amount of trait and error variance in the dimensions. The results
showed that the measures of the SSES under the partial aggregation model
are highly reliable and replicate across the two independent samples in the
sense of demonstrating equality of variance-covariance matrices. Further,
the examination of the partial aggregation model by gender revealed that
men and women also exhibited identical variance-covariance matrices for
the composite measures of the SSES. The findings for the across-sample and
across-gender analyses suggest that the structure of responses to the SSES is
quite generalizable for the partial aggregation model.
The partial disaggregation model yielded insights into the SSES at a more
fine-grained and less abstract level of analysis than the aggregate models.
This model captured the unique dimensions of the SSES and demonstrated
that each dimension is reliably measured and achieves discrimination from
the others in a moderate sense. Yet, the findings revealed that significant
amounts of common variance exist across the measures of the three dimen-
