AbstractThe objective of this study was, firstly, to determine the factor structure and factor invariance of the Zung Self-Rating Depression Scale (ZSDS) and, secondly, to justify its use in coronary patients (CPs) and healthy people (HP). Two comparable samples of males were studied: 217 CPs and 191 HP. Exploratory and confirmatory factor analyses (EFA and CFA) for ordinal data were carried out with Mplus. Two models obtained from all participants in this study and another two, the model of Shafer (2006) from a meta-analysis and that of Barefoot et al. (2000) with CPs, were analyzed in CFA. A two-factor structure was supported by EFA in both samples, but none of the models showed adequate goodness-of-fit for the CPs and the HP in CFA. Only the two and three-factor models obtained from the combined sample of CPs and HP showed adequate goodness-of-fit for HP. The ZSDS showed good reliability, replicated the prevalence of depressive symptoms found in other studies and was able to distinguish between CPs and HP. We conclude that the best fit is obtained from the two-factor solution in HP, that the factor structure of the ZSDS is not invariant and is linked to positively and negatively worded items.

Background: In Alzheimer’s disease and related disorders (ADRD) research, common outcome measures include cognitive and functional impairment, as well as persons with mild cognitive impairment (pwMCI) and care partner self-reported mood and quality of life. Studies commonly analyze these measures separately, which potentially leads to issues of multiple comparisons and/or multicollinearity among measures while ignoring the latent constructs they may be measuring. Objective: This study sought to examine the latent factor structure of a battery of 12-13 measures of domains mentioned above, used in a multicomponent behavioral intervention (The HABIT® program) for pwMCI and their partners. Methods: Exploratory factor analysis (EFA) involved 214 pwMCI-partner pairs. Subsequent Confirmatory factor analyses (CFA) used 730 pairs in both pre- and post-intervention conditions. Results: EFA generated a three-factor model. Factors could be characterized as partner adjustment (29.9%), pwMCI adjustment (18.1%), and pwMCI impairment (12.8%). The subsequent CFA confirmed our findings, and the goodness-of-fit for this model was adequate in both the pre- (CFI = 0.937; RMSEA = 0.057, p = 0.089) and post-intervention (CFI = 0.942; RMSEA = 0.051, p = 0.430) groups. Conclusion: Results demonstrated a stable factor structure across cohorts and intervention conditions suggesting that three broad factors may provide a straightforward and meaningful model to assess intervention outcome, at least during the MCI phase of ADRD.

AbstractThe growing interest in mindfulness from the scientific community has originated several self-report measures of this psychological construct. The Mindful Attention and Awareness Scale (MAAS) is a self-report measure of mindfulness at a trait-level. This paper aims at exploring MAAS psychometric characteristics and validating it for the Portuguese population. The first two studies replicate some of the original author’s statistical procedures in two different samples from the Portuguese general community population, in particular confirmatory factor analyses. Results from both analyses confirmed the scale single-factor structure and indicated a very good reliability. Moreover, cross-validation statistics showed that this single-factor structure is valid for different respondents from the general community population. In the third study the Portuguese version of the MAAS was found to have good convergent and discriminant validities. Overall the findings support the psychometric validity of the Portuguese version of MAAS and suggest this is a reliable self-report measure of trait-mindfulness, a central construct in Clinical Psychology research and intervention fields.

Abstract. This article examines the internal validity of the French version of the Big Five Questionnaire for Children (BFQ-C). We first performed confirmatory factor analyses (CFA) to determine the fit of the factor structure identified in previous research on the BFQ-C and then used exploratory factor analyses. A sample of 399 children (192 boys and 207 girls) recruited from elementary schools completed the BFQ-C in their classrooms. Participants were 8 to 12 years old with a mean age of 9.58 years (SD = 0.98). The results indicated poor goodness-of-fit statistics for the CFA solution. Exploratory factor analysis improved the model fit markedly over conventional CFA. The factor structure of the French version of the BFQ-C suggested reasonable fit for the five intercorrelated factors corresponding to the Big Five with the exploratory factor analyses, even if the fifth factor appeared to be more problematic than the other 4 factors.

IntroductionThe Depression, Anxiety and Stress Scales are widely used in clinical and non-clinical populations, both in research and clinical settings. The need for briefer but valid and reliable instruments has motivated the reduction of the original 42-item scale to a short 21-version. On Portuguese samples, Pais-Ribeiro et al. (2004) found that the original 3-factor solution (stress, anxiety and depression) explained 50.35% of the variance and in an exploratory analysis; Xavier et al. (2015) presented a two factor solution and a modified three-factor solution with a sample of pregnant women, both with adequate factors’ reliability (< 0.70) and explaining above 50% of the variance.AimsBased on the previous results of factor analysis with Portuguese samples, the present study aimed to perform confirmatory factor analyses (using Mplus software) to evaluate which dimensional structure best fitted the data.MethodsThe sample comprised 234 students (78.2% female), between 18–26 years old (M = 20.55; SD = 1.66). Eighty-five percent of the participants were on their first three years of college education. Participants filled the Portuguese version of the DASS-21.ResultsOur results showed that the original 3-factor structure had the best model fit [χ2(186) = 475.465, P < 0.05; RMSEA = 0.082, 90% CI = 0.073–0.091; CFI = 0.918; TLI = 0.908; SRMR = 0.05]. Good reliability was found for all subscales (0.92 for stress, 0.87 for anxiety and 0.91 for depression subscale).ConclusionsThe DASS-21 is a reliable instrument that, with student populations, seems to have better performance when used with a 3-factor structure. Further research is needed to confirm this structure in Portuguese clinical samples.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Elméleti háttér: A szelekció–optimalizáció–kompenzáció modell rugalmas alkalmazkodási folyamatokat feltételez, amelyekkel az idősek képesek pozitív egyensúlyt elérni életkoruk nyereségei és veszteségei között. Ezen stratégiák mérésére alkották meg a Szelekció– Optimalizáció–Kompenzáció Kérdőívet, majd annak rövid változatát (SOC-12). Cél: Kutatásunk egyik célja a SOC-12 kérdőív magyar nyelvre történő adaptálása és pszichometriai jellemzőinek vizsgálata volt. Módszerek: Keresztmetszeti kérdőíves kutatásunkat 155 fős, 60 éves és afeletti, kognitív zavarban nem szenvedő mintán végeztük el (átlagéletkor: 74,6 év, SD = 7,9 év, terjedelem: 60–98 év; nemi megoszlás: 125 [81%] nő és 30 [19%] férfi). Mérőeszközök: SOC-12 kérdőív, Connor–Davidson Reziliencia Skála, Rövid Geriátriai Depresszió Skála. Eredmények: A teljes SOC-12 kérdőív illeszkedési mutatói a megerősítő faktorelemzésben messze elmaradnak az elfogadhatótól. Feltáró faktorelemzéssel kétfaktoros szerkezet rajzolódott ki. A SOC-12 skála egészét reprezentáló (mind a négy alskála tételeiből tartalmazó) 1. faktor tételei jó megbízhatóságú skálát képeznek (McDonald-ω [95% CI]: 0,83 [0,79–0,87]. A 2. faktoron töltődő tételekből létrehozott alskála esetén az ω [95% CI]: 0,57 [0,43–0,69], így megbízhatósága elmarad a kívánatostól. Az általunk módosított, 7-tételes SOC-kérdőív konvergens és diszkriminatív validitása egyaránt optimális, alátámasztja a skála által mért erőforrás-felhasználási stratégiák érvényességét. Következtetések: Kutatásunk alapján a módosított SOC-12 kérdőív a magyar idős populációban jó pszichometriai mutatókkal rendelkezik. Eredményeink alátámasztják, hogy segítségével az időskori alkalmazkodási folyamatok összességében jól mérhetők. A szelekciós stratégiák önálló mérése azonban az alacsony megbízhatóságú tételek miatt nem lehetséges. A kérdőív használhatóságát elősegíti, hogy a kitöltés és az értékelés egyaránt rövid időt vesz igénybe.Background: The selection-optimization-compensation model assumes flexible adaptation processes by which the elderly are able to achieve a positive balance between gains and losses of their lives. The Selection-Optimization-Compensation (SOC-12) questionnaire was developed to measure these strategies. Aim: The aim of our research was to adapt the SOC-12 questionnaire to Hungarian language and to establish its psychometric properties. Methods: Our cross-sectional research was conducted on a sample of 155 people aged 60 and over (mean age: 74.6 years, SD = 7.9 years, range: 60–98 years; gender distribution: 125 (81%) women and 30 (19%) male). Measures: SOC-12 Questionnaire, Connor-Davidson Resilience Scale, Geriatric Depression Scale Short Form. Results: Based on our results, the fit of the original 4 factor structure of the SOC-12 questionnaire very weak. Exploratory factor analysis revealed a two-factor structure. The items of factor 1, which represent the whole of the SOC-12 scale (containing items from all subscales), form a scale with good reliability (McDonald’s ω [95% CI]: 0,83 [0,79–0,87]. In the case of the subscale created from the items loading on the factor 2, the ω-value [95% CI] is 0.56 [0.43–0.69], so its reliability is less than acceptable. Both convergent and divergent validity of the modified SOC questionnaire is optimal, supporting the validity of the resource use strategies measured by the scale. Conclusions: Based on the current study, the original SOC-12 questionnaire had to be modified. Our results support that the modified questionnaire makes measurable adaptation processes in old age. Independent measurement of selection strategies is not possible due to low reliability items. The scale provides a short, easy response to measure these strategies, and both completion and evaluation take a short time.

AbstractThe objective of this study is to develop and validate a scale of subjective resilience for students 12–17 years old. Items covered adverse situations due to parents’, peers’ and teachers’ actions. The validation process included the analysis on the generalizability of the factor structure and of relationships of resilience scores with different kinds of protective and vulnerability factors -goal orientations and learning-oriented classroom motivational climate (CMC)-. A total of 471 students answered four questionnaires. Confirmatory factor analyses, reliability analysis and correlation and regression analyses were carried out. Results showed: (a) that factor structure was well defined; (b) that resilience scale had good reliability; (c) that scores correlated as expected with protective-vulnerability factors such as goal orientations and CMC defined by teachers’ teaching-patterns, and (d) that students’ attribution of perceived change in resilience to teachers’ work depended on the degree in which CMC was learning oriented. Theoretical and practical implications are discussed.

Abstract Objectives The objective of this study is to validate three mental health scales in a targeted sample of pregnant Arab women living in Qatar: the Kuwait University Anxiety Scale, the Perceived Stress Scale, and the Edinburgh Postnatal Depression Scale. Methods Random split-half exploratory factor analysis and confirmatory factor analyses (n = 336; n = 331), conducted separately, were used to evaluate scale dimensionality, factor loadings, and factor structure of the KUAS, the PSS, and the EPDS. Results Fit statistics for the three scales suggested adequate fit to the data and estimated factor loadings were positive, similar in magnitude, and were significant. The final CFA model for the KUAS supported a 19-item, two factor structure. CFA models also confirmed 8- and 10-item, single-factor structures for the PSS and EPDS, respectively. Conclusions The validation of scales for these aspects of mental health in Arab pregnant women is critical to ensure appropriate screening, identification, and treatment to reduce the risk of sequelae in women and their children. Findings offer a useful comparison to mental-health scale validations in other Arab contexts.

Despite great interest in Mind Wandering, a fully validated questionnaire has been lacking. The Four Factors of Mind Wandering (4FMW) Questionnaire, presented here, meets this demand. First, 80 items were judged for content validity by two panels of experts. Those items that survived this content validity assessment were then tested using exploratory and confirmatory factor analyses on two independent samples of young adults. The 16 resulting items were shown to cluster into four factors (i.e., Failure in social interaction, Failure in interaction with objects, Unawareness, and Inattention). The 4FMW questionnaire showed good reliability, robust structure, and acceptable goodness-of-fit indices, as well as good convergent validity with another Mind Wandering questionnaire. Importantly, the 4FMW questionnaire was able to discriminate between attention-deficit/hyperactivity disorder and obsessive–compulsive disorder symptoms. The 4FMW Questionnaire is a reliable and valid instrument for assessing mind wandering in the young adult population.
