Examining the structural validity of the Strengths and Difficulties Questionnaire (SDQ) in a U.S. sample of custodial grandmothers

The authors examined the structural validity of the parent informant version of the Strengths and Difficulties Questionnaire (SDQ) with a sample of 733 custodial grandparents. Three models of the SDQ's factor structure were evaluated with confirmatory factor analysis based on the item covariance matrix. Although indices of fit were good across all 3 models, a model that included a newly hypothesized positive construal method factor in addition to the 4 symptom factors (Emotional Symptoms, Conduct Problems, Hyperactivity-Inattention, Peer Problems) and the single Prosocial Behavior factor originally intended for the SDQ provided the best representation of this instrument's latent structure. Structural validity was further evidenced by measurement invariance across grandparent race and grandchild gender and age, a conceptually meaningful pattern of cross-scale correlations, and the acceptable internal reliability estimates found for each subscale. Measurement and clinical implications of the results are discussed.     

Examining the Latent Structure of Posttraumatic Growth Between Male and Female Survivors in the Immediate Aftermath of a Flash Flood Disaster

The study examined and compared the latent structure of posttraumatic growth (PTG) based on three proposed models: 1-factor, 3-factor and 5-factor models in order to (1) find out the factor structure that has the best fit for the Filipino sample; (2) find out the factor structure that best represents PTG in the immediate aftermath of a flash flood disaster; and (3) examine the generalizability of the best-fitted model across gender. A sample of 895 survivor-respondents answered the Posttraumatic Growth Inventory (PTGI) within a month after a deadly flash flood. Based on the best-fitted model, a multi-group comparison between male and female was conducted to determine gender generalizability. Results showed that the 3-factor model comprising of Changes in Self/Positive Life Attitudes, Philosophy of Life, and Relating to Others fitted best in contrast to the other two models. The data also demonstrated the generalizability of the 3-factor model across gender, with invariance in factor loadings, item intercepts, factor variance and covariance, and factor means.     

Multidimensional structure and measurement invariance of school engagement

This study examined the multidimensional structure and measurement invariance of a school engagement instrument using confirmatory factor analysis (CFA), exploratory structural equation modeling (ESEM), bifactor CFA (BCFA), and bifactor ESEM (BESEM). Participants consisted of 1731 students in Grades 9 - 11 from the 4-H Study of Positive Youth Development in the United States. The use of the CFA, ESEM, BCFA, and BESEM models was expected to provide more insight into the cross-loading and hierarchical structures of school engagement. We found empirical evidence to support the (a) tripartite factor structure of school engagement, (b) existence of cross-loadings and hierarchical structures, (c) measurement invariance across gender (male vs female) and race (European American vs African American), and (d) expected latent means differences by gender.     

Factorial Structure and Measurement Invariance of the Innovative Behavior Questionnaire

The article presents an analysis of the factorial structure and measurement invariance of the Innovative Behavior Questionnaire, developed by Scott and Bruce. Although the instrument is widely used to capture individuals' innovative behavior, very little evidence concerning its psychometric properties is available. A time‐lagged study among 382 employees was conducted to check the factorial structure of the questionnaire, using confirmatory factor analysis, as well as its measurement invariance across gender and time. One‐factor structure (with correlated error terms of first three items) and strict invariance across time and across gender of the Innovative Behavior Questionnaire were demonstrated. As such, the measure can be used as a reliable tool for capturing individuals' innovative behavior by self‐report.     

Confirming the three-factor structure of the quality of relationships inventory within couples

The current study further validates the Quality of Relationships Inventory (QRI; G. R. Pierce, I. G. Sarason, & B. R. Sarason, 1991) by evaluating its factor structure in a sample of 572 partners from 286 couples. Confirmatory factor analysis was used to compare 3 different models of the QRI and to investigate the invariance of the factor structure of the QRI across gender and across relationship satisfaction. Analyses revealed that a 3-factor solution--consisting of 3 different but interrelated factors (a 7-item support factor, a 12-item conflict factor, and a 6-item depth factor)--best accounted for the data. The authors' findings suggest that full metric invariance holds across gender and across relationship satisfaction in the female subsample, whereas only partial metric invariance could be established for relationship satisfaction in the male subsample.     

An examination of the first/second-grade form of the pictorial scale of perceived competence and social acceptance: Factor structure and stability by grade and gender across groups of economically disadvantaged children

We tested the structure of the Pictorial Scale of Competence and Social Acceptance (PSPCSA) across groups of first and second grade children from economically disadvantaged backgrounds. We used confirmatory factor analysis, including latent mean structures analysis, to test the fit of competing PSPCSA factor models and examined invariance across time and gender. Cohort 1 data were used to find a best fitting model. Cohorts 2 and 3 data were used for model cross-validation and invariance testing across time. Gender differences were examined with the multiple indicators, multiple causes model. We found support for a time invariant three-factor model but uncovered issues of concern related to score reliability. Consistent with the hypothesized decline in children's early optimistic bias, we found a statistically significant moderate decline in perceptions of cognitive and peer competence over time. In addition, we identified differences between boys and girls: (a) on perceptions of cognitive competence and (b) across several items within each of the PSPCSA subscales.     

Evidence for a Higher-Order ESEM Structure of ADHD in a Sample of Chinese Children

Exploratory structural equation modeling (ESEM) solutions have been proposed to represent the factor structures of attention-deficit/hyperactivity disorder (ADHD) in recent literature, yet no studies have assessed those structures in Chinese children. The primary aim of this study was to comprehensively examine the factor structures of the Chinese version of the ADHD Rating Scale-IV (ADHD RS-IV): Home Version. Data on 458 Chinese children aged 3–8 years (boys: 246; 54%) were used to test and compare eleven factor models: confirmatory factor analysis (CFA) models (one-factor, two-factor and three-factor), second-order CFA model, bifactor CFA models (two and three specific factors), ESEM models (two-factor and three-factor), second-order ESEM model, and bifactor ESEM models (two and three specific factors). The results showed that, overall, ESEM models displayed better fit than CFA models. Specifically, the second-order ESEM model with three first-order factors best represented of the ADHD factor structure in our sample. In addition, measurement invariance testing results showed that scalar invariance was established across gender, age and informant groups. Implications for future research are discussed.

     

Invariance of a two-factor model of Social Dominance Orientation across gender

This research examined the measurement and structural invariance of the 16-item Social Dominance Orientation (SDO) scale across gender. The Social Dominance Theory (SDT) invariance hypothesis proposes that men are higher than women in SDO. Tests of this hypothesis have compared summary scores with t-tests, but there is no psychometric work of measurement invariance across gender, which makes interpretation of t-test comparisons problematic. Some research suggests the scale captures two distinct factors: support for group-based dominance (GBD) and general opposition to equality (OEQ). However, gender differences in GBD and OEQ have mixed findings. Results replicated the two-factor structure. Multiple-group CFA indicated that loadings, intercepts, factor variances, and factor covariance are equivalent across gender. Males demonstrated higher latent means of GBD and OEQ, supporting the SDT invariance hypothesis.     

Confirmatory Factor Analysis of the Structure of Adult ADHD Symptoms

Previous research has examined the factor structure of ADHD symptoms in adults using confirmatory factor analysis and there is mixed support for two-factor, three-factor, or more complex bifactor models. The current study re-examines these factor structures on the basis of not only overall model fit, but also criteria such as chi-square difference tests, invariance, reliability, and validity. Three datasets were pooled to form a total sample of 430 adults (50% female). Participants completed questionnaires assessing their ADHD symptoms, education, psychopathology, and parenting (the latter as validity variables). Although the bifactor models demonstrated the best fit, the reliability and construct replicability of specific factors in these models was poor. The three-factor model had good fit and demonstrated good reliability, validity, construct replicability, and some invariance across gender and dataset. Our results replicate previous studies that find superior fit for bifactor models. However, the superior statistical fit may reflect only the increased complexity of these models. The more parsimonious three-factor model may demonstrate stronger validity and clinical utility.     

Evaluation of the Bifactor Structure of the Dispositional Hope Scale

The Dispositional Hope Scale (DHS; Snyder et al., 1991) is composed of items assessing an individual's perception of his or her agency and pathways. This study examined support for the bifactor structure and relation of the factors in this model with depressive symptoms. It also examined cross-gender measurement invariance for the bifactor model. A community sample of 413 women and 257 men completed the DHS. Confirmatory factor analysis indicated more support for the bifactor model than the 1- and 2-factor models. Results also indicated full measurement invariance across gender for the bifactor and the 2-factor models. The general and the specific agency factors, but not the specific pathways factor, correlated with depressive symptoms. The better support for the bifactor model suggests that ideally hope has to be measured and examined by factors reflecting high covariance for agency and pathways, and also factors reflecting unique variances for agency and pathways. The support for full cross-gender measurement invariance indicated that there are no differences in measurement and scaling properties for the DHS across ratings provided by women and men, and therefore the DHS ratings can be scored in the same way for women and men.     

Testing Measurement Invariance of the Dark Triad Dirty Dozen in a Belgian Adult Sample

The Dirty Dozen (Jonason & Webster, 2010) is a frequently used concise version of the Dark Triad to measure three socially aversive personality traits: Machiavellianism, psychopathy and, narcissism. The present study has examined measurement invariance in a sample of Belgian adults. The present study aims to assess measurement invariance of the Dutch version of the Dirty Dozen measure across gender in a large city-based representative adult sample in Belgium (N = 1587). Multi-group first-order confirmatory factor analysis for categorical indicators was utilized. In addition, unique associations between Dirty Dozen traits, trait self-control and, acceptance of illegitimate norms were examined in a series of structural equation models. Results indicated that the internal consistency of the Dirty Dozen subscales was good for Machiavellianism (α = 0.80) and narcissism (α = 0.80), but modest for psychopathy (α = 0.64). The hypothesized three correlated factors model with separate factors for Machiavellianism, psychopathy and, narcissism provided a poor fit for men and women. Invariance testing across gender showed evidence for weak invariance only, indicating that the underlying latent factors are measured the same way with the same metric in the two populations. However, we were not able to establish strong measurement invariance. Observed group differences should be interpreted with caution. Furthermore, Machiavellianism and psychopathy were strongly associated with trait self-control in both men and women. Strong correlations were found between acceptance of illegitimate norms and Dirty Dozen traits, Machiavellianism and, psychopathy, but not with narcissism.     

Gender Differences in the Measurement of Creative Problem‐Solving

Despite significant scholarly attention, the literature on the existence and direction of gender differences in creativity has produced inconsistent findings. In the present paper, we argue that this lack of consensus may be attributable, at least in part, to gender‐specific inconsistencies in the measurement of creative problem‐solving. To explore this possibility, we empirically tested assumptions of multiple‐group measurement invariance using samples borrowed from four recent studies that assessed creative problem‐solving (J.D. B arrett et al., 2013; K.S. H ester et al., 2012; D.R. P eterson et al., 2013; I.C. R obledo et al., 2012). Across the four samples, apparent gender differences emerged on all three components of S.P. B esemer & K. O 'Q uin's (1999) three‐facet model of creativity (i.e., quality, originality, and elegance) such that, on average, females appeared to exhibit higher baseline levels of creativity. However, in light of violations of measurement invariance assumptions across genders found in these samples, comparisons such as these may not ultimately be appropriate. Although the underlying factor structure and factor loadings on a unitary creativity factor were consistent across gender (i.e., weak factorial invariance), measurement in‐equivalence assumptions were violated at the subfacet level (i.e., strong factorial invariance). Implications of these findings for understanding gender differences in creative problem‐solving are discussed.     

Factor structure and measurement invariance of the multidimensional driving style inventory across gender and age: An ESEM approach

The Multidimensional Driving Style Inventory (MDSI) is the most comprehensive measure of typical driving behavior to date and has been frequently used to compare driving styles across different groups of drivers, particularly between gender- and age-related groups. However, the factor structure of MDSI has not been clearly established and its measurement invariance has not been demonstrated. The goal of the present study was to examine the internal structure and measurement invariance of the MDSI across gender and age. A sample of 1277 drivers from Argentina responded to the Argentinian version of the MDSI. Exploratory structural equation modeling (ESEM) was used to test the factor structure and measurement invariance across females (n = 602) and males (n = 675), and across young (18–29, n = 558), adult (30–49, n = 395) and older (50 and older, n = 317) drivers. The results showed that a 36-item six-factor ESEM model represented by risky, angry, dissociative, anxious, distress-reduction and careful and patient driving styles was the best model based on fit indices and interpretability. Configural, weak and strong invariance of the six-factor ESEM model across gender and age was also supported. The MDSI in its Argentinian version is equivalent across gender and age, supporting the validity of previous research findings examining gender and age differences in driving styles. Future studies should examine the measurement invariance of the MDSI across other relevant driving-related variables.     

Measurement invariance across gender and ethnicity on the Emotional Quotient Inventory 2.0

This study investigated the measurement invariance of the Emotional Quotient Inventory 2.0 across gender and ethnic groups in South Africa. The sample consisted of 1 144 working adults (female = 49.8%. black = 36.2%, white = 29.8%; other = 34%; age range = 18 to 74 years). Multiple group factor analysis was conducted to test for configural, metric, and scalar invariance. Results suggest that the assessment is largely invariant at configural and metric levels across gender and ethnic groups. At scalar level, full invariance was achieved for ten of the fifteen scales across gender and one scale across ethnicity. Partial scalar models were explored for all other scales. Overall, the evidence seems to suggest that the scores from the Emotional Quotient Inventory 2.0 scales had similar meanings for different gender and ethnic groups. However, for a few scales across gender, and more so for ethnicity, it seems that participant responses might also be influenced by factors other than the underlying latent constructs. Thus, while the scales of the assessment appears to be largely invariant at the configural and metric levels, a more nuanced picture emerged at scalar level with partially invariant models, especially across ethnic groups.     

Factorial Invariance of the PedsQL™ 4.0 Generic Core Scales Child Self-Report Across Gender: A Multigroup Confirmatory Factor Analysis with 11,356 Children Ages 5 to 18

The measurement of health-related quality of life (HRQOL) in pediatric medicine and health services research has grown significantly over the past decade. The paradigm shift toward patient-reported outcomes (PROs) in clinical trials and population studies has provided the opportunity to emphasize the value and critical need for pediatric patient self-report. In order for HRQOL/PRO outcome comparisons to be meaningful for gender group analyses, it is essential to demonstrate the factorial invariance of an instrument. This study examined factorial invariance of the 23-item PedsQL? 4.0 Generic Core Scales across gender groups for child self-report ages 5–18. Multigroup Confirmatory Factor Analysis (MGCFA) was performed specifying a five-factor model across gender groups. The analyses were based on 11,356 children recruited from clinic, school, and community populations. Strict factorial invariance across gender groups was demonstrated based on stability of the Comparative Fit Index (CFI) between the models, and indices of practical fit including the Root Mean Squared Error of Approximation (RMSEA), the Non-Normed Fit Index (NNFI), and the Parsimony Normed Fit Index (PNFI). The findings support an equivalent five-factor structure on the PedsQL? 4.0 Generic Core Scales across gender groups. Based on these data, it can be concluded that boys and girls studied interpreted items on the PedsQL? 4.0 Generic Core Scales in a similar manner. These findings have implications for studies of gender differences in health outcomes.     

The Perceived Stress Scale: Evaluating Configural, Metric and Scalar Invariance across Mental Health Status and Gender

The Perceived Stress Scale (PSS; Cohen, Kamarck, & Mermelstein, Journal of Health and Social Behavior, 24: 385–396, 1983) and its derivatives are among the most commonly used self-report measures of subjective global stress. Several factorial models of the PSS have been proposed; however, which of these structures reliably measures individuals with mental illness remains unclear. Moreover, despite the detection of gender differences in perceived stress, factorial invariance between genders has not yet been tested with the PSS. Confirmatory factor analysis evaluating six prevailing factorial models of the PSS among a large sample of psychiatric patients and a matched community sample supported a two-factor model. Multiple group analysis established configural, metric and scalar invariance of this model across gender, but only configural invariance across samples differing by mental health status. Implications are that gender differences can be cautiously interpreted as true mean differences rather than artifacts of measurement bias; however, mean perceived stress factor scores should not be compared directly across psychiatric and non-psychiatric samples.     

The Peer Interaction in Primary School Questionnaire: testing for measurement equivalence and latent mean differences in bullying between gender in Egypt,Saudi Arabia and the USA

The Peer Interaction in Primary School Questionnaire (PIPSQ) was developed to assess individuals’ levels of bullying and victimization. This study used the approach of latent means analysis (LMA) within the framework of structural equation modeling (SEM) to explore the factor structure and gender differences associated with the PIPSQ in a sample of Egyptian (N = 361), Saudi Arabian (N = 350) and USA (270) children. Results of the confirmatory factor analysis are consistent with previous work and support the cross-cultural validity of the PIPSQ factor structure. The PIPSQ factor loadings were invariant across Egyptian and Saudi samples, whereas only partial invariance was met between Egyptian or Saudi samples and the USA sample. Full measurement invariance was met between gender within the three cultures, that is the PIPSQ was useful to compare bullying and victims between gender within the three cultures, but it is only valid to compare those two constructs between Egyptian and Saudi boys and girls. The results indicated that Egyptian and Saudi boys/girls had a higher level of bullying than American boys/girls, whereas no differences were displayed among the three cultures on the victimization subscale. Boys had a higher level of bullying than girls in the three cultures, and boys and girls had a similar level of victimization in three cultures.     

Validating the Student-Teacher Relationship Scale: testing factor structure and measurement invariance across child gender and age in a Dutch sample

The Student-Teacher Relationship Scale (STRS) is widely used to examine teachers' relationships with young students in terms of closeness, conflict, and dependency. This study aimed to verify the dimensional structure of the STRS with confirmatory factor analysis, test its measurement invariance across child gender and age, improve its measurement of the dependency construct, and extend its age range. Teachers completed a slightly adapted STRS for a Dutch sample of 2335 children aged 3 to 12. Overall, the 3-factor model showed an acceptable fit. Results indicated metric invariance across gender and age up to 8years. Scalar invariance generally did not hold. Lack of metric invariance at ages 8 to 12 primarily involved Conflict items, whereas scale differences across gender and age primarily involved Closeness items. The adapted Dependency scale showed strong invariance and higher internal consistencies than the original scale for this Dutch sample. Importantly, the revealed non-invariance for gender and age did not influence mean group comparisons.     

A cross-sectional evaluation of the factorial invariance of anxiety sensitivity in adolescents and young adults

This study examined the cross-sectional factorial invariance of anxiety sensitivity in an ethnically diverse sample of adolescents (n = 173; mean age 15.5 years) and young adults (n = 291; mean age 20.1 years). Research in adult and youth samples suggests that anxiety sensitivity is best understood as a hierarchical construct with several lower-order factors. Factor models based on previous research using both adult and youth samples were compared and a hierarchical model with three lower-order factors provided the best fit to the data. Results supported the hypothesis that the factor structure of the Anxiety Sensitivity Index was invariant across age and gender. The factor scores also demonstrated differential correlations with symptoms of anxiety and depression. Results are discussed with regard to construct validation and understanding the structure of anxiety sensitivity in youth.
