The present study examined the factor structure of the Differential Ability Scales–Second Edition (DAS-II) core subtests from the standardization sample via confirmatory factor analysis (CFA) using methods (bifactor modeling and variance partitioning) and procedures (robust model estimation due to nonnormal subtest score distributions) recommended but not included in the DAS-II Introductory and Technical Handbook. CFAs were conducted with the three DAS-II standardization sample age groups (lower early years [age = 2:6–3:5 years], upper early years [age = 3:6–6:11 years], school age [7:0–17:11 years]) using standardization sample raw data provided by NCS Pearson, Inc. Although most DAS-II core subtests were properly associated with the theoretically proposed group factors, both the higher order and bifactor models indicated that the g factor accounted for large portions of total and common variance, whereas the group factors (Verbal, Nonverbal, Spatial) accounted for small portions of total and common variance. The DAS-II core battery provides strong measurement of general intelligence, and clinical interpretation should be primarily, if not exclusively, at that level.

When the Differential Ability Scales–Second Edition (DAS-II) was developed, the instrument’s content, structure, and theoretical orientation were amended. Despite these changes, the Technical Handbook did not report results from exploratory factor analytic investigations, and confirmatory factor analyses were implemented using selected subtests across the normative age groups from the total battery. To address these omissions, the present study investigated the theoretical structure of the DAS-II using principal axis factoring followed by the Schmid–Leiman procedure with participants from the 5- to 8-year-old age range to determine the degree to which the DAS-II theoretical structure proposed in the Technical Handbook could be replicated. Unlike other age ranges investigated where at most 14 subtests were administered, the entire DAS-II battery was normed on participants aged 5 to 8 years, making it well suited to test the full instrument’s alignment with theory. Results suggested a six-factor solution that was essentially consistent with the Cattell–Horn–Carroll (CHC)-based theoretical structure suggested by the test publisher and simple structure was attained. The only exception involved two subtests (Picture Similarities and Early Number Concepts) that did not saliently load on a group factor. Implications for clinical practice are discussed.

Individually administered intelligence measures are commonly used in diagnostic work, but there is a continuing need for research investigating possible test bias among these measures. One current intelligence measure, the Differential Ability Scales, Second Edition (DAS-II), is a test with growing popularity. The issue of test bias, however, has not been thoroughly investigated with the DAS-II. The current study investigated whether the DAS-II demonstrates systematic construct bias when used with children from three racial and ethnic groups—African American, Asian, and Hispanic—when compared to non-Hispanic Caucasian children. Multi-group confirmatory factor analyses with data from the DAS-II standardization sample were used to assess whether the constructs and measurement of constructs were invariant across groups. Results indicate cross-group internal structure validity in the DAS-II, and thus a lack of construct bias. Minor differences were found, but these differences do not affect the calculation of composite scores on the DAS-II and thus would not result in unfair scoring for the groups involved. Results of this study support the appropriateness of the DAS-II for clinical use with these racial and ethnic groups.

The Brief COPE (Coping Orientation to Problems Experienced) is a frequently used questionnaire assessing 14 theoretically derived coping mechanisms, but psychometric research has suggested inconsistent results concerning its factor structure. The aim of this study was to investigate primary and secondary order factor structures of the Brief COPE during the COVID-19 pandemic by testing 11 different models by confirmatory factor analyses and to assess differences between sex, age groups, and relationship status. Altogether, 529 respondents from Austria and Germany participated in a web-based survey. Results supported the originally hypothesized 14-factor structure but did not support previously described higher-order structures. However, bass-ackwards analyses suggested systematic overlap between different factors, which might have contributed to different factor solutions in previous research. Measurement invariance across sex, age groups, and relationship status could be confirmed. Findings suggest that cultural and situational aspects as well as the functional level should be considered in research on theoretical framing of coping behavior.

The present study explores the factorial structure and the degree of measurement invariance of 12 divergent thinking tests. In a large sample of German students (N = 1328), a three-factor model representing verbal, figural, and numerical divergent thinking was supported. Multigroup confirmatory factor analyses revealed that partial strong measurement invariance was tenable across gender and age groups as well as school forms. Latent mean comparisons resulted in significantly higher divergent thinking skills for females and students in schools with higher mean IQ. Older students exhibited higher latent means on the verbal and figural factor, but not on the numerical factor. These results suggest that a domain-specific model of divergent thinking may be assumed, although further research is needed to elucidate the sources that negatively affect measurement invariance.

Objective This study was aimed to examine the factor structure and factorial invariance across gender of the Frost Multidimensional Perfectionism Scale-Chinese version (FMPS-CV). Methods The FMPS-CV was completed by 2451 undergraduates. Confirmatory factor analyses (CFA) were performed to verify its factorial validity, and Multigroup CFA were performed to examine its factorial invariance across gender. Gender differences were compared on scores of FMPS-CV. The internal consistency and test-retest reliability were also detected. Clinical characteristics were compared between adaptive and maladaptive perfectionists categorized by positive and negative scores of FMPS-CV. Results CFA supported the six-factor structure of FMPS-CV, and Multigroup CFA evidenced its factorial invariance across gender. No significant gender differences were found. The adaptive perfectionists scored significantly lower on clinical variables than maladaptive perfectionists. Moreover, the reliability indicators met the standards. Conclusions The good psychometrics properties of FMPS-CV supported it could be used to assess perfectionism in Chinese young adults.

Confirmatory factor analyses were conducted to test the factor structure of several versions of Levenson's (1973) locus of control scales. Two- and three-factor models based on all 24 of Levenson's items and on 20 of her items were tested. The 3-factor models provided a good fit. Models proposed by R. M. Shewchuk, G. A. Foelker Jr., and G. Niederehe (1990) and R. M. Shewchuk, G. A Foelker Jr., C. J. Camp, and F. Blanchard-Fields (1992) also provided a good fit of the data. In concurrent and prospective tests of the predictive ability of the various models, the 24 and 20 item versions of Levenson's models accounted for a significant amount of variance In depressive symptomatology. The three-factor models revealed that only scores on the chance scale reliably predicted time 2 depressive symptomatology. Neither of the models proposed by Shewchuk and colleagues accounted for a significant amount of variance.

<p>Introduction: The Transgression-Related Interpersonal Motivation (TRIM-18) Inventory is an instrument that assesses episodic forgiveness. This scale is composed of three subscales: <em>avoidance</em>, <em>revenge</em> and <em>benevolence</em>. The present study examined the dimensionality of the Spanish version of the TRIM-18 (TRIM-18-S) and provided evidence of validity and reliability. Method: A total of 943 participants completed the TRIM-18-S.  A subset of 277 participants completed additional measures of empathy, anger, and information regarding the relation with the offender. Results: The TRIM-18-S showed good psychometric properties, and confirmatory factor analyses revealed a three-factor structure. Conclusions: The scale presents adequate psychometric properties for its potential use in a Spanish population.</p><p> </p>

Aim: The Qualities of Sore Throat Index (QuaSTI) assesses the status of patient-reported pharyngeal pain. One study used QuaSTI in isolation; a separate study used QuaSTI plus the Sore Throat Scale (STS). Both studies also used a Sore Throat Pain Intensity Scale (STPIS). This study evaluates STS and STPIS as instruments to refine the QuaSTI. Materials & methods: Correlational analysis determined the degree of association between STPIS and STS. Confirmatory factor analyses evaluated the proposed factor structure of QuaSTI. Results: A strong correlation between STS and STPIS (r = 0.91; p < 0.01), supports the use of STS in QuaSTI. Analyses confirm a three-factor structure for the 10-item QuaSTI and validate inclusion of an additional item to create an 11-item tool for measuring pharyngeal pain. Conclusion: The QuaSTI represents a robust and validated tool for measuring therapeutic effects in patients with pharyngitis.
