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.

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)     

Measurement invariance of the Gifted Rating Scales—School Form across five cultural groups.

This study examined measurement invariance of the Gifted Rating Scales—School Form (GRS–S) across the United States, Puerto Rico, China, South Korea, and Turkey, using multigroup confirmatory factor analysis. A total of 1,817 students were rated by 287 teachers using either translated versions of GRS–S or the original English GRS–S. Results indicate a similar factor structure for the GRS–S across the five locations; six factors with each of the 72 items equivalently loaded to the same latent variable across groups. The metric invariance test and the factor variance and covariance invariance tests reveal that the patterns of factor loadings and the factor variances and covariances are invariant across the five groups. Moreover, the scalar invariance test indicates that item means are equivalent across the groups. These results suggest that the GRS–S has intercultural utility and can be similarly interpreted. Implications and limitations of the present research for gifted identification are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Assessing changes in the meaning of children's behavior: Factorial invariance of teachers' temperament ratings.

Tested the assumption that the same behavioral rating scale may be used over a wide age range, using temperament ratings provided by 24 teachers of 564 kindergarten through 4th-grade children. A LISREL analysis supported the hypothesized 3-factor model and established factorial invariance. The consistency of the factor structure over grade and the similarity of this structure to the findings from other factor analytic studies suggest that teachers may organize information about student behavior along the same dimensions regardless of the grade they teach. Such invariance may result from the demands of the teaching task rather than actual covariation among student behaviors. (40 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Factorial validity and consistency of the MBI-GS across occupational groups in Norway.

The present study tested the factorial validity of the Maslach Burnout Inventory-General Survey (MBI-GS) among 694 participants from 4 different occupational groups. Confirmatory factor analyses of the total sample, as well as multigroup analyses and analyses of each of the 4 occupational groups separately, indicated that the original 3-factor model of the MBI-GS provided a good fit to the data. Internal consistencies of the subscales of the MBI-GS were acceptable, and test-retest reliability indicated relative stability of scores over a 6-month interval. These results indicate that the proposed 3-factor structure of the MBI-GS, based on 16 items, can be replicated in the total sample as well as across different occupational groups in Norway.

Structural invariance of vocational interests across Japanese and American cultures.

Two samples of college students (Japanese, N?=?373; American, N?=?401) were given the Inventory of Occupational Preferences (T. J. G. Tracey & J. Rounds, 1996a), and the structural invariance across cultures was examined at the item and at various scale levels. Correlations of principal-components factor loadings demonstrated that the item structure was similar across cultures. Three separate scale structures were examined: Holland's six-type circular model, Tracey and Round's eight-type circular model, and Tracey and Round's spherical representation. The fit of the six-type and spherical models to the Japanese sample was significantly worse than their fit to the U.S. sample. There were no differences in cross-cultural fit for the eight-type model. Few structure differences were found between and within genders.

Investigating the structure and age invariance of episodic memory across the adult lifespan.

The structure of episodic memory was investigated by assessing different modalities of material (verbal, figural, and spatial) and different types of tests (recall, cued recall, and recognition). A 3-factor model that distinguished among modalities of material was found to be the best representation of memory and the verbal, figural, and spatial memory factors exhibiting construct validity. This 3-factor modality of material model also demonstrated configural, metric, and structural age invariance across a sample of adults (N = 327) between the ages of 18 and 94. There was evidence that latent constructs corresponding to recall, cued recall, and recognition could be distinguished from one another within the verbal domain but not within the figural and spatial domains. A mediation model examining the retrieval constructs was examined within the verbal domain, and there were unique age-related influences on cued recall and recall performance. This result is consistent with findings that increased age is associated with increased difficulty in retrieving information. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Longitudinal invariance of adult psychometric ability factor structures across 7 years.

The hypothesis that psychometric ability tests retain equivalent factor structures across a 7-year interval was examined in a sample of 984 persons (disaggregated into 6 cohort groups: M ages at first test?=?32, 46, 53, 60, 67, and 76), assessed in 1984 and 1991 as part of the Seattle Longitudinal Study. A best fitting measurement model was estimated for 20 psychometric tests marking the 6 primary abilities of Inductive Reasoning, Spatial Orientation, Perceptual Speed, Numeric Facility, Verbal Ability, and Verbal Recall. Gender was partialed out at the variable level by including a gender factor. Weak factorial invariance over time was demonstrated for all cohorts. Configural invariance could be demonstrated across all cohort groups. However, weak factorial invariance across groups could be accepted for all but the youngest and oldest groups. Latent means were modeled for the accepted solutions across time and cohort groups. (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.

Structural invariance of cognitive abilities across the adult life span: A cross-sectional study.

This study examined the hypothesis that psychometric tests retain equivalent factor structures across samples widely differing in age. We estimated a best-fitting measurement model for 17 psychometric tests covering the 5 primary abilities of Inductive Reasoning, Spatial Orientation, Verbal Ability, Numerical Ability, and Perceptual Speed, using a sample of 1,621 participants (ages 22 to 95) from the 5th wave of the Seattle Longitudinal Study. We disaggregated the participants into 9 subsets (M ages?=?29, 39, 46, 53, 60, 67, 74, 81, and 90) and tesed the fit of the accepted model for each subset. We confirmed configural invariance for all subsets, but could not establish either complete or incomplete metric invariance for any set. These results confirm the stability of factor patterns across age but indicate serious limitations for valid cross-age comparisons of individual markers of psychometric abilities in age-comparative studies.

Validation of the Social Interaction Anxiety Scale and the Social Phobia Scale across the anxiety disorders.

The psychometric adequacy of the Social Interaction Anxiety Scale (SIAS; R. P. Mattick & J. C. Clark, 1989), a measure of social interaction anxiety, and the Social Phobia Scale (SPS; R. P. Mattick & J. C. Clark, 1989), a measure of anxiety while being observed by others, was evaluated in anxious patients and normal controls. Social phobia patients scored higher on both scales and were more likely to be identified as having social phobia than other anxious patients (except for agoraphobic patients on the SPS) or controls. Clinician-rated severity of social phobia was moderately related to SIAS and SPS scores. Additional diagnoses of mood or panic disorder did not affect SIAS or SPS scores among social phobia patients, but an additional diagnosis of generalized anxiety disorder was associated with SIAS scores. Number of reported feared social interaction situations was more highly correlated with scores on the SIAS, whereas number of reported feared performance situations was more highly correlated with scores on the SPS. These scales appear to be useful in screening, designing individualized treatments, and evaluating the outcomes of treatments for social phobia.

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.

Scale for the assessment of reality testing: Reliability, validity, and factorial invariance.

Factor analysis of a reality testing inventory designed by M. Bell et al (unpublished) produced 3 subscales (Reality Distortion, Uncertainty of Perception, and Hallucinations and Delusions) interpreted as dimensions of the reality-testing ego function. Subscales were assessed for internal consistency and for age, gender, and social desirability biases, using 7 criterion groups of schizophrenic, schizoaffective, and borderline individuals. Schizophrenics, schizoaffectives, and borderlines were most pathological on Reality Distortion and Hallucinations and Delusions subscales, while Borderlines were highest on Uncertainty of Perception. Discriminant analysis differentiated inpatient schizophrenics from inpatient schizoaffectives with 92% accuracy. (18 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Factor analysis of the Attitudes Toward Disabled Persons Scale—Form A.

Factor analysis of the attitudes of 133 rehabilitation and agency practitioners and trainees yielded four major factors: Coping-Succumbing, Emotional Need-Emotional Satisfaction, Sensitivity-Self-Consciousness, and Inferred Morality. The findings of this study are compared and contrasted with findings using similar instruments with different populations so as to explore psychometric issues.

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.

Validity and construct contamination of the Racial Identity Attitude Scale—Long Form.

The Racial Identity Attitude Scale—Long Form (RIAS–L; J. E. Helms & T. A. Parham, 1996) is likely to be the instrument of choice in future research on African American racial identity development, but little is known about its psychometric properties. RIAS-L data from 275 African American community members and students were collected, and a series of analyses (i.e., correlations, multiple regressions, and confirmatory modeling) was conducted to explore convergent and discriminant validity. Overall, results were mixed, generally revealing limited support for the RIAS-L's convergent and discriminant validity and highlighting concerns regarding the Preencounter and Encounter subscales.
