Abstract. Most evidence available has found multidimensional solutions for the General Health Questionnaire’s (GHQ12) structure, contrary to the authors’ original one-factor solution. Recently, the study of method effects associated to negatively worded items has been included in the study of GHQ12’s factor structure, and the most common conclusion has been that the best-fitting structure is a single factor confounded by response bias. Current study analyzes the factor structure of the Portuguese version of the GHQ12. The sample consisted of 1,332 young Angolan adults. Previously-reported structures, including one-factor and multidimensional substantive ones, as well as bifactor structures, and models positing method effects among negatively worded items were tested via Confirmatory Factor Analyses. Results suggested that a three substantive factor solution adequately represented the scale’s underlying structure. The emerging factors were dysphoria, social dysfunction, and loss of confidence. Method effects did not play a clear role in explaining the multidimensionality observed in the factor structures tested for the GHQ12.

Abstract Background This study’s main purpose was to examine the psychometric properties of FoMOs’ adaptation among the Indonesian adolescents’ population. The second aim was to investigate the concurrent validity of the Indonesian version to provide evidence for the validity. Also, FoMOs’ difference level between demographic variance analyses was performed. Method The study involved a cross-sectional online survey design with 638 Indonesian adolescents aged 16–24 (M = 19.08, SD = 14.70). FoMO was measured by a 16-item that has been modified from the original 10-item. Exploratory and confirmatory factor analyses were carried out to study its scores’ evidence of structural validity. Besides, to study its scores’ evidence of convergent, discriminant, and predictive validity concerning other variables such as stress, anxiety, and depression (Depression and Anxiety Stress Scale-21), and general health condition (General Health Questionnaire Scale-12), correlation analyses were conducted. To study the sensitivity, we assessed the effect of sociodemographic and social media use on the scale’s ability to identify the population’s risk to the FoMO by conducting analyses of variance. The Cronbach alpha values (α = .93) indicated that internal consistency of the scale was at an adequate level. Results Exploratory factorial analyses revealed adequate adjustment for the new version of the scale showing the three factorial structures. Confirmatory factor analyses showed that the 12-item of Indonesian FoMO had a good fit (χ2/df = 289.324/51; goodness-of-fit index (GFI) = 0.928; RMSEA = 0.086; comparative fit index (CFI) = 0.915; normed fit index (NFI) = 0.899; parsimony normed fit index (PNFI) = .695; Tucker–Lewis index (TLI) = 0.890). Conclusion This study has shown that the modified 12-item Fear of Missing Out Scale is a valid and reliable instrument for Indonesian adolescents. It showed that the Indonesian version of Fear of Missing Out Scale has adequate psychometric properties to measure Indonesian adolescents’ online behavior.

In the past decade, extensive interest has been directed toward the Dark Triad (i.e., Machiavellianism, narcissism, and psychopathy), popularly assessed by the Short Dark Triad (SD3). Nevertheless, relatively little research has been conducted on the SD3’s factor structure. We investigated the SD3’s psychometric properties in three studies with three independent samples, using exploratory and confirmatory factor analyses ( N1 = 1,487; N2 = 17,740; N3 = 496). In all three studies, Machiavellianism and psychopathy items displayed large general factor loadings, and narcissism larger specific factor loadings. In subsequent studies, two- and three-factor models fitted the data similarly, with the best fitting model being a bifactor model with items from Machiavellianism and psychopathy modelled as one specific factor, and narcissism as a second specific factor. On this basis, we suggest that the SD3 does not seem to capture the different mental processes theorized to underlie the similar behaviors generated by Machiavellianism and psychopathy. Additionally, we recommend the use of a single SD3 composite score, and not subscale scores, as subscales contain small amounts of reliable variance beyond the general factor.

Summary: The present work was aimed at assessing the factorial structure of Gottfredson's (1981) cognitive map of occupations. Participants, 500 Spanish pupils aged 14 years, were presented 129 occupations derived from Shinar's (1975) questionnaire, and asked to rate each occupation on one of 10 different scales derived from Gottfredson 's work: femininity, masculinity, prestige, income, realistic, research, artistic, social, entrepreneurial, and conventional. Exploratory and confirmatory factor analyses were conducted on the 129 × 10 matrix of means. The best solution was found to be a three-factor solution, with an independent social status factor and two correlated factors: gender and creativity.

OBJECTIVE: Investigate the structural coherency of the 60-item version of the General Health Questionnaire via exploratory and confirmatory factor analyses. METHOD: The study design is a cross-sectional survey. A random sample of 146 individuals from the city of Divinópolis-MG volunteered to participate in the present study and responded to the 60-item version of the General Health Questionnaire adapted and validated for use in Brazil. Statistics consisted of exploratory and confirmatory factor analysis. Reliability was estimated using Cronbach's alpha method. RESULTS: Alpha coefficients for all five content scales of the General Health Questionnaire were high (α > 0.8). For four of the five scales, a unifactorial model of constituent items provided a good fit to the data. Items comprising the fifth scale, Psychic Stress, exhibited a two-correlated factor structure. A factor analysis of scores for the five scales yielded strong evidence of coherency, with all scales loading substantially on a single common factor. CONCLUSION: The General Health Questionnaire shows good psychometric coherency as evidenced by high internal consistency and unidimensionality of all but one of its constituent scales, and uniformly high loadings of all scales on a single overarching factor. These results are consistent with prior findings from the General Health Questionnaire developmental study and Brazilian adaptation studies.

Abstract. The Strengths and Difficulties Questionnaire (SDQ) has been widely adopted as a measure of child and adolescent mental health and behavioral problems. However, despite an impressive number of studies demonstrating its psychometric properties, appropriate analyses of the instrument's underlying structure have not been reported. We conducted confirmatory factor analyses on matched data obtained from a large community sample of 7-17-year-olds, their parents, and their teachers. The analyses indicated that the reputed factor structure was not supported, with none of the subscales being unidimensional. Further, each informant group appeared to respond differently to the questionnaire. Considering the findings in relation to the stringency of the tests used to evaluate the SDQ, its utility, and previous research on its clinical validity, it is suggested that the SDQ be used with caution and in conjunction with other forms of assessment.

The purpose of this study was to explore the psychometric properties of an Arabic translation of the Gifted Rating Scales–School Form (GRS-S) on a national sample of 907 students from Cycle 1 (Grades 1 to 4) and Cycle 2 (Grades 5 to 10) from five governorates in Oman (Muscat, Dhofar, Al-Batinah North, Al-Sharqiyah South, and Al-Dhahira). The replicability of the GRS-S factor structure was examined using the confirmatory factor analysis (CFA). The CFA results supported the six-factor solution of the original scale. Also, Cronbach’s alpha reliability coefficients of the GRS-S subscales ranged from .91 to .96. The criterion-related validity for the GRS-S scores was supported as statistically significant correlations were found between the GRS-S subscales and the Gifted and Talented Rating Scales–Second edition (GATES-2), students’ academic achievement, and the scores of the Profile of Creative Abilities (PCA) rating scale. The metric invariance results revealed that the six-factor structure of GRS-S was equally applicable across gender and grade levels.

ObjectiveRecent studies into the factorial structure of the 12-item version of the General Health Questionnaire (GHQ-12) have shown that it was best represented by a single substantive factor when method effects associated with negatively worded (NW) items are considered. The purpose of the present study was to examine the presence of method effects, and their relationships with demographic covariates, associated with positively worded (PW) and/or NW items.DesignA cross-sectional, observational study to compare a comprehensive set of confirmatory factor models, including method effects associated with PW and/or NW items with GHQ-12 responses.SettingRepresentative sample of all employees living in Catalonia (Spain).Participants3050 participants (44.6% women) who responded the Second Catalonian Survey of Working Conditions.ResultsA confirmatory factor analysis showed that the best fitting model was a unidimensional model with two additional uncorrelated method factors associated with PW and NW items. Furthermore, structural equation modelling (SEM) revealed that method effects were differentially related to both the sex and age of the respondents.ConclusionIndividual differences related to sex and age can help to identify respondents who are prone to answering PW and NW items differently. Consequently, it is desirable that both the constructs of interest as well as the effects of method factors are considered in SEM models as a means of avoiding the drawing of inaccurate conclusions about the relationships between the substantive factors.

The Beck Hopelessness Scale (BHS) is an instrument for assessing cognitive thoughts among suicidal persons. Previous studies have identified different factor structures of the BHS. However, results were not conclusive. The aim of this study was to test the factor structure of the BHS in a sample of Italian individuals (N = 509) from the community, and secondarily to investigate correlations between the BHS, depression (Beck Depression Inventory Second Edition), and personality traits (Zuckerman-Kuhlman-Aluja Personality Questionnaire). Following recommendations of previous investigations, we utilized a 5-point response format. We applied a second-order Confirmatory Factor Analyses and tested for the model invariance. The results suggest that besides a single second-order factor, a second-order three-factor solution is also reasonable, in line with Beck’s theorization.
