Background The World Health Organization Disability Assessment Schedule 2.0 (WHODAS 2.0) is a generic measure of functional impairment and disability but to date no studies have reported its applicability in a population of Syrian refugees. Aims The aim of this study was to explore the psychometric properties and factor structure of the Arabic version of the WHODAS 2.0 among a population of Syrian refugees in a Jordanian refugee camp setting. The tool was used as part of a screening procedure for a randomised controlled trial assessing the effectiveness of a low-intensity psychological intervention. Method A representative sample of Syrian refugees (n = 650) were screened to assess levels of functional impairment and psychological distress. The screening results were used to explore the internal consistency and dimensionality of the WHODAS 2.0. We assessed level of convergence with the validated Kessler 10-item Psychological Distress Scale (K10), which assesses psychological distress. Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were conducted to explore the construct validity and factor structure of the WHODAS 2.0. Results The mean baseline WHODAS 2.0 score was 20.5 (s.d. = 7.6). The internal consistency was acceptable (Cronbach's alpha 0.74), with all 12-items appearing to be related to the same construct. The WHODAS 2.0 was positively correlated with the K10 (r = 0.57, P < 0.001). The results of the EFA identified a three-factor solution accounting for 51% of variation, corresponding with factors related to self-activities, external activities and self-care. CFA results indicated good fit of the three-factor solution. Conclusions The results indicated that the WHODAS 2.0 has a three-factor solution and is an acceptable screening tool for use among Syrian refugees.

Purpose: To evaluate the factorial and concurrent validity and internal consistency reliability of the World Health Organization Disability Assessment Schedule 2.0 (WHODAS 2.0) 12-item version in persons with spinal cord injuries.Method: Two hundred forty-seven adults with spinal cord injuries completed an online survey consisting of the WHODAS 2.0 12-item version and measures of various psychosocial variables.Results: The initial confirmatory factor analysis (CFA) revealed that both the theoretical hierarchical model and the 1-factor model of the WHODAS 2.0 12-item version exhibited a poor fit with the data. Subsequent exploratory factor analysis (EFA) revealed a 3-factor solution consisting of the factors Activities/Participation, Self-Care, and Mobility. Each factor demonstrated adequate internal consistency. These results were confirmed by a secondary CFA. In the concurrent validity analysis, the Activities/Participation factor had the strongest relationships with the psychosocial variables under study (life satisfaction, core self-evaluations, community participation, and health-related quality of life).Conclusion: The WHODAS 2.0 12-item version is not unidimensional in persons with spinal cord injuries as predicted but instead yields a three-factor solution. However, the Activities/Participation factor appears to be the most valid measure of disability impact in persons with spinal cord injuries. Other implications of the use of the WHODAS 2.0 12-item version are discussed.

Objective: To assess the validity of the Finnish translation of the 12-item World Health Organization Disability Assessment Schedule (WHODAS 2.0). Design: Cross-sectional cohort survey study. Setting: Physical and Rehabilitation Medicine outpatient university clinic. Subjects: The 501 consecutive patients with chronic musculoskeletal pain. Main measures: Exploratory factor analysis and a graded response model using item response theory analysis were used to assess the constructs and discrimination ability of WHODAS 2.0. Results: The exploratory factor analysis revealed two retained factors with eigenvalues 5.15 and 1.04. Discrimination ability of all items was high or perfect, varying from 1.2 to 2.5. The difficulty levels of seven out of 12 items were shifted towards the elevated disability level. As a result, the entire test characteristic curve showed a shift towards higher levels of disability, placing it at the point of disability level of +1 (where 0 indicates the average level of disability within the sample). Conclusions: The present data indicate that the Finnish translation of the 12-item WHODAS 2.0 is a valid instrument for measuring restrictions of activity and participation among patients with chronic musculoskeletal pain.

The Impact

The current paper takes a tourism-focused perspective to evaluate the impact of COVID-19 on the attitude of the tourist to travel. For this, the present paper conceptualize, develop, and validate the multi-dimensional scale on preventive measures of COVID-19. Further, we have developed a new model named Financial Crisis from Contagious Disease (FCCD)-stimulator to assess the impact of the virus on the short term performance of the global tourism industry. The study was exploratory, where initial items were generated through the qualitative method. The purification of the scale items and extraction of the distinct factors were performed through a quantitative approach (exploratory factor analysis). Further, the confirmatory factor analysis was used to validate the scale. The findings of the study manifested a multi-dimensional scale measuring the preventive measures of COVID-19 in the tourism context. The research renders a 25 item scale with four distinct factors named Isolation (7-items), Quarantine (7-items), Social Distancing (6-items), and Community Containment (5-items). The present scale will add to the literature of COVID-19 in the context of the tourism industry. The authors assume that this will be the first comprehensive scale, prepared on the guidelines of the World Health Organization (WHO), that will measure the effect of preventive measures of COVID-19 on the attitude of the tourist to travel during a pandemic situation.

Recent research into schizotypal traits has been concerned with the number and nature of these personality dimensions. Earlier exploratory factor analytic work using a wide variety of scales (the CSTQ) has generated a four‐factor solution but other solutions have been provided by other investigators. This study uses confirmatory factor analysis on a large sample to compare several plausible models of the relationships between scales. These models include a two‐factor model separating ‘positive’ from ‘negative’ schizotypal features, a three‐factor model including features of cognitive disorganization, and the four‐factor model generated previously by exploratory factor analysis. Results offer support for the four‐factor solution as the only structure meeting multiple criteria for goodness of fit. The relevance of Eysenck's dimensions, and the P scale in particular, to the results is discussed. Attention is drawn to the possibility that the factors describe predispositions of risk of psychotic disorders beyond that of schizophrenia.

Purpose: This study aimed to test the construct validity of an instrument to measure student professional behaviors in entry-level occupational therapy (OT) students in the academic setting. Methods: A total of 718 students from 37 OT programs across the United States answered a self-assessment survey of professional behavior that we developed. The survey consisted of ranking 28 attributes, each on a 5-point Likert scale. A split-sample approach was used for exploratory and then confirmatory factor analysis. Results: A three-factor solution with nine items was extracted using exploratory factor analysis [EFA] (n=430, 60%). The factors were ‘Commitment to Learning’ (2 items), ‘Skills for Learning’ (4 items), and ‘Cultural Competence’ (3 items). Confirmatory factor analysis (CFA) on the validation split (n=288, 40%) indicated fair fit for this three-factor model (fit indices: CFI=0.96, RMSEA=0.06, and SRMR=0.05). Internal consistency reliability estimates of each factor and the instrument ranged from 0.63 to 0.79. Conclusion: Results of the CFA in a separate validation dataset provided robust measures of goodness-of-fit for the three-factor solution developed in the EFA, and indicated that the three-factor model fitted the data well enough. Therefore, we can conclude that this student professional behavior evaluation instrument is a structurally validated tool to measure professional behaviors reported by entry-level OT students. The internal consistency reliability of each individual factor and the whole instrument was considered to be adequate to good.

Abstract. The present study evaluated the psychometric properties of the Math Homework Purpose Scale (MHPS). After randomly splitting the sample ( N = 854) into two subsamples ( n = 427 and n = 427), we carried out exploratory factor analysis (EFA) on subsample 1 and confirmatory factor analysis (CFA) on subsample 2. The Kaiser-Meyer Olkin value of .88 indicated that EFA was appropriate for subsample 1. EFA results showed that a three-factor solution explained 72.2% of the variance. All ten of the MHPS items loaded quite substantially on three factors labeled Academic, Self-Regulatory, and Approval-Seeking. CFA results further showed that the MHPS was composed of three factors: Academic, Self-Regulatory, and Approval-Seeking. From this adequate level of measurement invariance, we further examined the latent mean difference across gender for the entire sample. Our findings showed no statistically significant mean differences in Academic, Self-Regulatory, and Approval-Seeking across gender. In addition, the HMPS was found to have adequate alpha reliability coefficients and omega coefficients. Concerning the validity evidence of the MHPS, Academic, Self-Regulatory, and Approval-Seeking purposes were positively correlated with homework effort, homework completion, and math achievement. The present study provides solid evidence that the MHPS is a reliable and valid measurement of math homework purposes.

Abstract. This study examines the latent structure of the Rahim Organizational Conflict Inventory – II (ROCI-II) in several samples of secondary school students. Findings from earlier studies conducted in adult populations suggested that the instrument has a four- or five-factor structure; however, the exploratory factor analysis (EFA) in this study yielded a three-factor (integrating, dominating, avoiding) solution, with most of the items associated with a fourth factor (Obliging) failing to load as predicted. A confirmatory factor analysis (CFA) replicated the three-factor solution satisfactorily. A multiple-group CFA indicated that the ROCI-II showed invariant measurement properties in male and female students and corroborated the concurrent validity of the three-factor solution. The integrating factor was related positively to a measure of perspective taking but negatively to a measure of reluctance to participate. The avoiding factor was associated with a measure of reluctance to participate. We discuss the implications of the results for understanding the latent structure of the ROCI-II in adolescents.

AbstractBackgroundRecent evidence showed substantial negative mental health outcomes associated with the current COVID-19 pandemic, including trauma-related symptoms although the effects on the Italian population who were subjected to unprecedented nationwide lockdown measure remains unknown. The Global Psychotrauma Screen (GPS) is a brief instrument designed to assess a broad range of trauma-related symptoms with no available validation in the Italian population.AimsThis study aimed at examining the factor structure of the Italian version of the GPS in a general population sample exposed to the COVID-19 pandemic and at evaluating trauma-related symptoms in the Italian population in the context of specific COVID-19 related risk factors associated with the implementation of lockdown measures and social distancing.MethodsCross-sectional web-based observational study, as part of a long-term monitoring programme of mental health outcomes in the general population. 18147 participants completed a self-report online questionnaire to collect key demographic data and to evaluate trauma-related symptoms using the GPS, PHQ-9, GAD-7, ISI and PSS. Validation analyses included both exploratory and confirmatory factor analysis, and correlation analyses.ResultsExploratory factor analyses supported both a two-factor and a three-factor model. Confirmatory factor analysis showed that a one-factor solution that was used as a baseline comparison showed acceptable fit indices, the two-factor solution showed good fit indices, but the best fitting model was a three-factor solution, with Negative Affect (symptoms of depressed mood, anxiety, irritability), core Post-traumatic Stress Symptoms (PTSS) (avoidance, re-experiencing, hyperarousal and insomnia) and Dissociative symptoms. GPS Risk factors as well as specific COVID-19 related stressful events, were associated with GPS total as well as the three factor scores.ConclusionsOur data suggest that a wide range of trauma-spectrum symptoms were reported by a large Italian sample during the COVID-19 pandemic. The GPS symptoms clustered best in three factors: Negative Affect symptoms, Core PTSS, and Dissociative symptoms. In particular high rates of core PTSS and negative affect symptoms were associated with the COVID-19 pandemic in Italy and should be routinely assessed in clinical practice.

The literature in achievement goals includes mixed results as to the factor structure of achievement goal measures, particularly the Achievement Goal Questionnaire, Revised (AGQ-R). In a sample of 1,496 undergraduate students (600 men, 891 women, 5 gender unreported; M age = 20.6 yr., SD = 3.2), the AGQ-R was subjected to an exploratory factor analysis that suggested three factors. Then, in a different sample of 1,125 undergraduate students (270 men, 750 women, 5 gender unreported; M age = 21.7 yr., SD = 5.4), the measure was subjected to a confirmatory factor analysis, in which a three-factor solution, again, showed the best fit to the observed data. The implications of these results for the measurement of achievement goals are discussed.

Whereas both Blatt (1974) and Beck (1983) postulated the existence of two basic cognitive-personality vulnerabilities to depression—sociotropic/anaclitic and autonomous/introjective—recent research and theorizing suggest that self-criticism is a third dimension of vulnerability. To examine the supposition that sociotropy, autonomy, and self-criticism constitute three distinct dimensions of vulnerability, we administered the Personal Style Inventory (PSI; Robins et al., 1994), six items from the Depressive Experiences Questionnaire (DEQ; Blatt, D’Afflitti, & Quinlan, 1976) and the Brief Symptoms Inventory (BSI; Derogatis & Melisaratos, 1983) to 203 Israeli young adults. Confirmatory factor analysis (CFA) provided support for the hypothesized three-factor solution. Regression analyses indicated that each of these dimensions was associated with psychopathology. Findings encourage further integrative work in the field of personality vulnerability.
