Psychometric properties of reverse-scored items on the CES-D in a sample of ethnically diverse older adults.

Reverse-scored items on assessment scales increase cognitive processing demands and may therefore lead to measurement problems for older adult respondents. In this study, the objective was to examine possible psychometric inadequacies of reverse-scored items on the Center for Epidemiologic Studies Depression Scale (CES-D) when used to assess ethnically diverse older adults. Using baseline data from a gerontologic clinical trial (n = 460), we tested the hypotheses that the reversed items on the CES-D (a) are less reliable than nonreversed items, (b) disproportionately lead to intraindividually atypical responses that are psychometrically problematic, and (c) evidence improved measurement properties when an imputation procedure based on the scale mean is used to replace atypical responses. In general, the results supported the hypotheses. Relative to nonreversed CES-D items, the 4 reversed items were less internally consistent, were associated with lower item-scale correlations, and were more often answered atypically at an intraindividual level. Further, the atypical responses were negatively correlated with responses to psychometrically sound nonreversed items that had similar content. The use of imputation to replace atypical responses enhanced the predictive validity of the set of reverse-scored items. Among older adult respondents, reverse-scored items are associated with measurement difficulties. It is recommended that appropriate correction procedures such as item readministration or statistical imputation be applied to reduce the difficulties.

Factorial invariance of the Dyadic Adjustment Scale across gender.

The Dyadic Adjustment Scale (DAS; G. B. Spanier, 1976) is the most widely used inventory of relationship satisfaction in the social sciences, yet the question of whether it is measuring the same concept in men and women has never been addressed. In the current study, the authors examined the factor structure of the DAS in a sample of 900 currently married couples who participated in the Minnesota Twin Family Study. Confirmatory factor analysis was applied to a second-order factor solution with Spanier’s four factors (Dyadic Consensus, Dyadic Satisfaction, Dyadic Cohesion, Affectional Expression) loading on one higher order factor (Relationship Adjustment), to test for measurement invariance across gender. The second-order solution was relatively invariant across gender, even when taking into account the nonindependent nature of the data. This suggests that the best conceptualization of the DAS is one of a gender-invariant measure of marital adjustment with four distinct subfactors and that differences between men and women on any of these constructs can be interpreted by both clinicians and researchers as true mean differences rather than measurement bias.

The composition and structure of depressive symptomatology in renal disease.

Renal disease is an increasingly common illness among middle-aged and older adults, and is often associated with depression. The Center for Epidemiologic Studies Depression Scale (CES–D) is a widely used self-report screening measure on which responses generally conform to a 4-factor structure, with each factor loading onto a higher-order Depression factor. The current study examines whether this structure is supported among individuals with renal disease (both predialysis and posttransplant kidney disease patients). Persons with renal disease (n = 225) and healthy control participants (n = 230) were recruited from Vancouver General Hospital and the community. Participants completed the CES–D as part of an extended assessment. Confirmatory factor analytic models were computed for the renal disease and healthy control groups. Results support a 4-factor structure for CES–D responses in persons with renal disease and healthy controls. The hierarchical structure of CES–D responses also appears invariant between groups. Factor structure was similar between groups; only for Depressive Affect was the strength of association with the second-order factor greater among the renal disease than healthy control participants. Findings support similarity of CES–D factor structures between patients with renal disease and healthy individuals. Results suggest that the CES–D's 4 factors contribute to measurement of a higher-order Depression factor in both groups; furthermore, 3 of 4 factors appear invariant between groups. As such, this measure can be used confidently to quantify depressive symptoms in individuals with renal disease. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Relationship between age and aspects of depression: Consistency and reliability across two longitudinal studies.

In this study, the authors examined cross-sectional and longitudinal age and gender differences in each of the Center for Epidemiological Studies Depression Scale's 4 subscales of depressive symptomatology. Two independent studies (Sample 1 = 2,076; Sample 2 = 943) were used for purposes of establishing stability of findings. Results indicate a reasonable degree of stability among adults under 70 years of age. However, there were significant age-related increases in somatic symptoms and lack of well-being after approximately 70 years of age, whereas symptoms related to depressed affect and interpersonal problems remained stable. Notably, depressive affect symptoms remained stable given significant age-related somatic changes. The addition of comorbid physical illness to the analysis did not reduce the association between age and depressive symptoms, indicating that part of the association was not substantially accounted for by physical health.

Factor structure and invariance across gender of the Devereux Early Childhood Assessment protective factor scale.

Early childhood social–emotional assessment has traditionally focused on risk factors or psychopathology, and has less frequently examined protective factors that may serve to promote positive developmental outcomes for children. To advance conceptual models that include protective factors as key explanatory constructs, there is a need for quantitative measures of protective factors that are psychometrically sound and function similarly across different subgroups, including gender. This study examined the factor structure and factorial invariance across gender of the Devereux Early Childhood Assessment (DECA), one of the few measures to focus on protective behaviors. A total of 1,344 parents completed the DECA for a group of developmentally and economically at-risk children ages 2 to 5 years. Results of the confirmatory factor analysis, the first to be conducted on the DECA, revealed that the factor structure proposed by the authors of the DECA was adequate with some modifications. Multigroup comparisons by gender supported the invariance of the factor pattern coefficients and 26 of the 27 item intercepts, indicating that the items were functioning similarly across boys and girls. Suggestions for improving problematic item pairs and content are provided. This study can be viewed as part of the ongoing validation of the DECA and an important contribution to the strength-based assessment literature.

Factorial invariance of a campus climate measure across race, gender, and student classification.

Invariance analyses using multigroup confirmatory factor analysis were conducted to test a model of campus climate perceptions for its equivalence in a combined sample of 2,634 undergraduate and graduate university students across race, gender, and student status. Results suggested that a multidimensional model of campus climate comprised of psychological and behavioral climate dimensions appears to be supported for both undergraduate and graduate students across race/ethnicity and gender. Nonequivalence of factor loadings seen in all three invariance comparisons indicated that relationships between items and the underlying factors differed in magnitude on some climate dimensions between males and females, White and ethnic minority students, and graduate versus undergraduate students. Implications for future climate measurement and higher education policy and practice are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Factor structure and measurement invariance of the Women's Health Initiative Insomnia Rating Scale.

As part of the Women's Health Initiative Study, the 5-item Women's Health Initiative Insomnia Rating Scale (WHIIRS) was developed. This article summarizes the development of the scale through the use of responses from 66,269 postmenopausal women (mean age=62.07 years, SD=7.41 years). All women completed a 10-item questionnaire concerning sleep. A novel resampling technique was introduced as part of the data analysis. Principal-axes factor analysis without iteration and rotation to a varimax solution was conducted for 120,000 random samples of 1,000 women each. Use of this strategy led to the development of a scale with a highly stable factor structure. Structural equation modeling revealed no major differences in factor structure across age and race-ethnic groups. WHIIRS norms for race-ethnicity and age subgroups are detailed.

A multicultural assessment of adolescent connectedness: Testing measurement invariance across gender and ethnicity.

Counselors, psychologists, and evaluators of intervention programs for youth increasingly view the promotion of connectedness as an important intervention outcome. When evaluating these programs, researchers frequently test whether the treatment effects differ across gender and ethnic or racial groups. Doing so necessitates the availability of culturally and gender-invariant measures. We used the Hemingway: Measure of Adolescent Connectedness to estimate the factor structure invariance and equality of means across gender and 3 racial/ethnic groups with a large sample of middle school adolescents. From a practical perspective, the 10-scale model suggested factor structure invariance across gender and racial or ethnic (i.e., African American, Caucasian, and Latina/o) groups of adolescents. However, tests for partial invariance revealed some group difference on the factor loadings and intercepts between gender and ethnic/racial groups. When testing for mean equivalence, girls reported higher connectedness to friends, siblings, school, peers, teachers, and reading but lower connectedness to their neighborhoods. Caucasians reported higher connectedness to their neighborhoods and friends but lower connectedness to siblings than African Americans and Latinos. African Americans reported the highest connectedness to self (present and future) but lowest connectedness to teachers. Latinos reported the lowest connectedness to reading, self-in-the-present, and self-in-the-future. Overall, this study reveals racial/ethnic and gender mean differences on several connectedness subscales and suggests the Hemingway subscales are, from a practical perspective, invariant across gender and ethnicity and therefore appropriate for most assessment and evaluation purposes.

Assessing the forms and functions of aggression using self-report: Factor structure and invariance of the Peer Conflict Scale in youths.

This study examined the structure of a self-report measure of the forms and functions of aggression in 855 adolescents (582 boys, 266 girls) aged 12 to 19 years recruited from high school, detained, and residential settings. The Peer Conflict Scale (PCS) is a 40-item measure that was developed to improve upon existing measures and provide an efficient, reliable, and valid assessment of four dimensions of aggression (i.e., reactive overt, reactive relational, proactive overt, and proactive relational) in youths. Confirmatory factor analyses showed that a 4-factor model represented a satisfactory solution for the data. The factor structure fit well for both boys and girls and across high school, detained, and residential samples. Internal consistency estimates were good for the 4 factors, and they showed expected associations with externalizing variables (i.e., arrest history, callous-unemotional traits, and delinquency). Reactive and proactive subtypes showed unique associations consistent with previous literature. Implications for the use of the PCS to assess aggression and inform intervention decisions in diverse samples of youths are discussed.

Measurement and structural invariance of parent ratings of ADHD and ODD symptoms across gender for American and Malaysian children.

The purpose of this study was to examine the measurement (configural, metric, scalar, and residual) and structural (factor variance, factor covariance, and factor means) invariance of parent ratings of the attention-deficit/hyperactivity disorder-inattention (ADHD-IN), ADHD-hyperactivity/impulsivity (ADHD-HI), and oppositional defiant disorder (ODD) symptoms as described in the Diagnostic and Statistical Manual of Mental Disorders (4th ed.; American Psychiatric Association, 1994) across boys and girls. In an American pediatric sample (N = 1,015) and a Malaysian elementary school-age sample (N = 928), there was strong support for configural, metric, scalar, residual, factor variance, and covariance invariance across gender within each sample. Both American and Malaysian boys had significantly higher scores on the ADHD-IN and ADHD-HI factor means than did girls, whereas only in the American sample did boys score significantly higher on the ODD factor than did girls. The implications of the results for the study of gender, ethnic, and cultural differences associated with ADHD and ODD are discussed.

Measurement Equivalence of the Center for Epidemiological Studies Depression Scale for Latino and Anglo Adolescents: A National Study.

The cross-ethnic measurement equivalence of the Center for Epidemiologic Studies Depression Scale (CES-D; L. S. Radloff, 1977) was examined using a subsample of adolescents (N=10,691) from the National Longitudinal Study of Adolescent Health. Configural and metric invariance, as well as functional and scalar equivalence, were examined for Anglo American, Mexican American, Cuban American, and Puerto Rican American youths age 12-18 years. Confirmatory factor analysis (CFA) in each group provided evidence of configural invariance for European and Mexican American adolescents but not for Cuban and Puerto Rican youths. A 2-group CFA for Anglo and Mexican Americans demonstrated partial metric invariance for these groups. Multigroup structural equation modeling indicated similar relations between CES-D scores and self-esteem for all 4 groups, supporting cross-ethnic functional and scalar equivalence. The results have implications for using the CES-D in cross-ethnic research and, more broadly, for the assessment and treatment of depression in Latinos.

Factor structure of the SOCRATES in a clinical sample of adolescents.

This study investigated the Stages of Change Readiness and Treatment Eagerness Scale (SOCRATES: W. R. Miller & J. S. Tonigan, 1996) in adolescents presenting for treatment of alcohol use disorder (AUD). The participants were 80 males and 43 females (mean age=16.8 years) who presented for AUD treatment (95.1% outpatient, 4.9% inpatient). Participants completed assessments at baseline and 1 year and provided information on alcohol use and related variables monthly between these 2 assessments. Principal-components and confirmatory factor analyses of the baseline SOCRATES identified 2 factors, Taking Steps and Recognition, which showed good internal consistency and concurrent and predictive evidence of validity. The results were interpreted as supporting the use of the SOCRATES with clinical samples of adolescents. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Factor structure of posttraumatic stress disorder as measured by the Impact of Event Scale–Revised: Stability across cultures and time.

This study examined the structure of posttraumatic stress disorder (PTSD) as measured by the Impact of Event Scale–Revised (IES-R; Weiss & Marmar, 1997), tested factorial invariance for samples of 235 Israeli emergency room patients and 306 U.S. undergraduate students, and then evaluated factorial invariance over multiple occasions within the emergency room sample. A four-factor structure representing intrusion, avoidance-numbing, hyperarousal, and sleep emerged as the preferred model. Configural invariance over groups was supported for this model. Likewise, configural invariance over occasions was demonstrated, but metric invariance was not fully supported, with variation in the loadings on the intrusion factor over time seemingly the source of misfit. Interpretations and conclusions center on sleep as a separate factor underlying the structure of the IES-R, the distinction between avoidance and numbing as a function of how the IES-R (vs. the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition) operationalizes the numbing feature of PTSD and possible shifts in the meaning of intrusion over time.

Factor structure of the acute stress disorder scale in a sample of Hurricane Katrina evacuees.

Acute stress disorder (ASD) is a poorly understood and controversial diagnosis (A. G. Harvey & R. A. Bryant, 2002). The present study used confirmatory factor analysis (CFA) to test the factor structure of the most widely used self-report measure of ASD, the Acute Stress Disorder Scale (R. A. Bryant, M. L. Moulds, & R. M. Guthrie, 2000), in a sample of Hurricane Katrina evacuees relocated to a Red Cross emergency shelter in Austin, Texas. Results indicated that the proposed 4-factor structure did not fit the data well. However, an alternate 2-factor model did fit the data well. This model included a second-order Distress factor (onto which the Reexperiencing, Arousal, and Avoidance factors loaded strongly) that was positively correlated with the Dissociation factor. Implications for the ASD construct and its measurement are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Development of a shortened center for epidemiological studies depression scale for assessment of depression in rheumatoid arthritis.

Objective: The purpose was to develop a short-form version of the Center for Epidemiologic Studies Depression Scale (CES-D) for the identification of persons with major depressive disorder (MDD) within a population with rheumatoid arthritis (RA). Study Design: Data were analyzed from 337 persons with RA. Forty-six participants met the diagnostic criteria for MDD; 291 participants were classified in the non-MDD category (including 21 participants with dysthymia and 18 participants with minor depressive disorder). A short-form version of the CES-D was developed, and multiple cutoff scores were examined. Results: A cutoff score of ≥5 from a 9-item, short-form CES-D was found to be generally as efficient as the more commonly used full-scale cutoff score of ≥16 for classifying participants with MDD within an RA population. Although the shortened CES-D scale (cutoff score ≥5) was slightly more sensitive, it also exhibited slightly less specificity than the full-scale cutoff score of ≥16. Conclusion: The results suggest that a short-form CES-D can be used to screen for MDD within an RA sample with a degree of efficiency that is generally comparable to that of the full-scale instrument.

Model stability of the 15-item Geriatric Depression Scale across cognitive impairment and severe depression.

The 15-item Geriatric Depression Scale (GDS) is used in a wide variety of clinical and research settings. The study's purpose was to further establish the validity of the 15-item GDS by exploring the underlying factor structure in a healthy, nondemented sample of older adults and then analyzing whether this factor structure remained stable across a sample of demented individuals and a sample of individuals with a history of depression 6 months after discharge from an inpatient psychiatric setting. A 2-factor model fit the data best in the exploratory analyses. The 2 factors, Life Satisfaction and General Depressive Affect, found in the nondemented sample (r = .39) remained stable across cognitive impairment (r = .12) but merged into a 1-factor model in the psychiatric sample (r = .93). The results indicate that nondepressed older adults with poor life satisfaction may be identified as depressed on screening instruments such as the 15-item GDS.

Latent structure and factorial invariance of a neuropsychological test battery for the study of preclinical Alzheimer's disease.

Objective: To examine the latent structure of a test battery currently being used in a longitudinal study of asymptomatic middle-aged adults with a parental history of Alzheimer's disease (AD) and test the invariance of the factor solution across subgroups defined by selected demographic variables and known genetic risk factors for AD. Method: An exploratory factor analysis (EFA) and a sequence of confirmatory factor analyses (CFA) were conducted on 24 neuropsychological measures selected to provide a comprehensive estimate of cognitive abilities most likely to be affected in preclinical AD. Once the underlying latent model was defined and the structural validity established through model comparisons, a multigroup confirmatory factor analysis model was used to test for factorial invariance across groups. Results: The EFA solution revealed a factor structure consisting of five constructs: verbal ability, visuospatial ability, speed & executive function, working memory, and verbal learning & memory. The CFA models provided support for the hypothesized 5-factor structure. Results indicated factorial invariance of the model across all groups examined. Conclusions: Collectively, the results suggested a relatively strong psychometric basis for using the factor structure in clinical samples that match the characteristics of this cohort. This confirmed an invariant factor structure should prove useful in research aimed to detect the earliest cognitive signature of preclinical AD in similar middle aged cohorts.

The factor structure and factorial invariance of the 12-item General Health Questionnaire (GHQ-12) across time: Evidence from two community-based samples.

This study provides new knowledge about the factor structure of the 12-item General Health Questionnaire (GHQ-12; D. Goldberg, 1972) through the application of confirmatory factor analysis to longitudinal data, thereby enabling investigation of the factor structure, its invariance across time, and the rank-order stability of the factors. Two community-based longitudinal adult samples with 1-year (n = 640) and 6-year (n = 330) follow-up times were studied. As a result, the correlated 3-factor model (i.e., Anxiety/Depression, Social Dysfunction, and Loss of Confidence) showed a better fit with both samples than the alternative models. The correlated 3-factor structure was also relatively invariant across time in both samples, indicating that the scale has good construct validity. The rank-order stabilities of the factors were low across time, which suggests that the GHQ-12 measures temporal mental state. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Validating the factor structure of the Self-Report Psychopathy Scale in a community sample.

Currently, there is no standard self-report measure of psychopathy in community-dwelling samples that parallels the most commonly used measure of psychopathy in forensic and clinical samples, the Psychopathy Checklist. A promising instrument is the Self-Report Psychopathy scale (SRP), which was derived from the original version the Psychopathy Checklist. The most recent version of the SRP (SRP-III; D. L. Paulhus, C. S. Neumann, & R. D. Hare, in press) has shown good convergent and discriminate validity and a factor structure similar to the current version of the Psychopathy Checklist (PCL-R; R. D. Hare, 1991, 2003). The analyses in the current study further investigated the viability of the SRP-III as a PCL-R-analogous measure of psychopathy in nonforensic and nonclinical samples by extending the validation process to a community sample. Using confirmatory factor analyses and logistic regressions, the results revealed that a four-factor oblique model for the SRP-III was most tenable, congruent with the PCL-R factor structure of psychopathy and previous research in which the SRP-III was administered to a student sample.

Relationship among gender, depression and needle sharing in a sample of injection drug users.

The authors explored the relationships among gender, needle sharing, and depression in a sample of 392 male and 121 female street drug users. Using the Risk Behavior Assessment (National Institute on Drug Abuse, 1991) and the Beck Depression Inventory--2 (A. T. Beck, R. A. Steer, & G. K. Brown, 1996), the authors found that women reported higher levels of depression than men and that sharers endorsed higher levels of depression than nonsharers. Further, the authors found that female sharers reported the highest levels of depression of all groups, that is, as compared with male sharers, female nonsharers, and male nonsharers, who did not differ from one another. This suggests the presence of a special dynamic between gender and depression that is related to higher rates of needle sharing among women.
