Background In the 11th revision of the International Classification of Diseases (ICD-11) posttraumatic stress disorder (PTSD) and the complex variant (CPTSD) were newly conceptualised. The International Trauma Questionnaire (ITQ) was developed as a brief self-report measure to screen for both disorders. The English original version has been rigorously tested and presents convincing psychometric properties. The aim of the current study was to validate the German version by means of item response theory (IRT). Method This is a secondary analysis of a representative, trauma-exposed adult sample from the German general population (N = 500). 1- and 2-parameter logistic IRT models (i.e. examination on an item level), diagnostic rates and confirmatory factor analyses were calculated. Results All items showed good model fit and acceptable to good performance aligning with the items of the English original except for item C1 (Long time to calm down) which had a high endorsement rate and a low discriminatory power yielding low information gain. CPTSD diagnostic rate of 3.2% was lower than in comparable literature. Confirmatory factor analysis deemed the six first-order, two second-order factors model superior. Conclusion Measurement and factorial validity of the German version of the ITQ was confirmed. The German translation matches the English original in most psychometric properties and can thus be used for research and clinical practice.

AbstractThis study applied a bifactor approach to investigate the structures and simultaneously compare the psychometric properties of three popular self-report internet addiction (IA) instruments. A bifactor confirmatory factor analysis was used to address the structures of the three scales, while the bifactor multidimensional item response model was employed to compare the psychometric properties of the three scales. Results of bifactor confirmatory factor analysis (CFA) showed that the bifactor structures were suitable for the three scales. These corresponding bifactor structures were used in the subsequent bifactor multidimensional item response theory (MIRT) analysis. Results of the bifactor MIRT showed that: three instruments of IA performed well as a whole; the Generalised Problematic Internet Use Scale (GPIUS) and Internet Addiction Test (IAT) provided more test information and had less standard error of measurement, which ranged from −3 to −1 standard deviations of theta or IA severity; the Game Addiction Scale (GAS) performed better than the other two scales in that it can provide more test information in the large area of IA severity (from −1 to +3 SDs). These suggest that the GPIUS and IAT may be the best choice for epidemiological IA studies and for measuring those with lower IA severity. Meanwhile, the GAS may be a good choice when we recruit those with various levels of IA severity.

Abstract. Rule-governed behavior is a central concept to explain complex human behavior from a functional-analytic standpoint. Recently, a self-report measure of a functional type of rule-following called generalized pliance has been developed – the Generalized Pliance Questionnaire (GPQ). The GPQ has two versions with 18 and 9 items, respectively. This study aimed to analyze the factor structure and psychometric properties of both GPQ versions in a Spanish online sample ( N = 846). Confirmatory factor analyses showed that the one-factor model obtained an acceptable fit in the GPQ-18, but an inadequate fit in the GPQ-9. The GPQ-18 showed measurement invariance across gender, excellent internal consistency, and convergent construct validity. According to the results, the GPQ-18 showed good psychometric properties in Spanish samples.

Confirmatory Factor

The present study examined the psychometric properties of the TEA Personality Test (TPT) in a sample of 23,062 Spanish adults. The TPT is a self-report questionnaire to be answered using a four-point Likert scale to assess personality at work and it is the third most frequently used tool by work psychologists in Spain. The reliability and validity analyses indicated that the TPT has adequate psychometric properties for the Spanish sample analyzed. Ordinal α was used to calculate the internal consistency reliability of the scales. Results were higher than those of Cronbach’s α reported in the TPT’s technical manual (p < .001). Results from confirmatory factor analyses showed an acceptable goodness-of-fit for the theoretical three factors of the TPT’s work personality model reported in the technical manual. The findings support the reliability and construct validity of the TPT.

Reliable and valid self-report questionnaires could be useful as initial screening instruments for social phobia in both clinical settings and general populations. The present study investigates the factor structure and psychometric properties of the Social Phobia and Anxiety Inventory for Children (SPAI-C) in a sample of 228 children from the Italian general population aged 8 to 11. The children were asked to complete the Italian version of the SPAI-C and the Screen for Child Anxiety Related Emotional Disorders (SCARED) questionnaire. Confirmatory factor analyses revealed that social phobia can be conceptualized as a unitary construct consisting of five distinct but interrelated symptom clusters named Assertiveness, General Conversation, Physical/Cognitive Symptoms, Avoidance, and Public Performance. Internal consistency of the SPAI-C total scores and two subscales was good; correlations between SPAI-C total scores and SCARED total scores/subscales ranged from moderate to high (Generalized Anxiety Disorder, for social phobia), with the SCARED Social Phobia subscale as the best predictor of SPAI-C total scores. The results indicate that the SPAI-C is a reliable and sensitive instrument suitable for identifying Social Phobia in the young Italian general population.

Abstract. By means of two studies, a self-report measure to assess self-efficacy in presentation and moderation skills, the SEPM scales, was validated. In study 1, factorial and construct validity were examined. A sample of 744 university students (41% females; more than 50% between 20 and 25 years) completed newly constructed self-efficacy items. Confirmatory factor analyses (CFAs) substantiated two positively correlated factors, presentation (SEPM-P) and moderation self-efficacy (SEPM-M). Each factor consists of eight items. The correlation patterns between the two SEPM subscales and related constructs such as extraversion, the preference for cooperative learning, and conflict management indicated adequate construct validity. In study 2, criterion validity was determined by means of latent change modeling. One hundred sixty students ( Mage = 24.40, SD = 4.04; 61% females) took part in a university course to foster key competences and completed the SEPM scales at the beginning and the end of the semester. Presentation and moderation self-efficacy increased significantly over time of which the latter was positively associated with the performance in a practical moderation exam. Across both studies, reliability of the scales was high, ranging from McDonald’s ω .80 to .88.

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.

<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>

The purpose of this study was to adapt the Statistics Anxiety Rating Scale (STARS) for a Greek student population. The STARS was administered to 890 Tertiary Education students in two Greek universities. It was performed a cross-validation study to examine the factorial structure and the psychometric properties with a series of confirmatory factor analyses. Results revealed a correlated six first-order factor model which provided the best fit to the data compared to a six-factor model with one superordinate factor. All six factors of the Greek version of the STARS presented convergent and discriminant validity and were internally consistent. Implications and limitations are discussed.
