Objective: The ability to reflect rationally on one's own anomalous experiences and to recognise that their conclusions are incorrect is called as cognitive insight. It influences the delusion proneness of patients with schizophrenia. Structured instruments to assess cognitive insight have not been validated in any Indian languages so far. Hence, we aimed to evaluate the validity and factor structure of Tamil version of Beck Cognitive Insight Scale (BCIS-T).Methods: One hundred and fifty consecutive patients with schizophrenia completed BCIS-T. We assessed their clinical insight with the reference standard, Schedule for Assessment of Insight-Expanded version (SAI-E). An independent psychiatrist evaluated their psychopathology using Brief Psychiatric Rating Scale (BPRS).Results: BCIS-T was internally consistent with Cronbach's α 0.67 and Guttman's split-half coefficient as 0.63. BCIS-T composite index documented convergent validity with SAI-E total score (ρ = 0.38; p < 0.001) and discriminant validity with BPRS (ρ = −0.02; p = 0.85). Factor analysis showed a four-factor structure, namely self-certainty, self-reflectiveness, openness to external feedback and infallibility of self-reflection. BCIS-T composite index had significant linear relationship with clinical insight and treatment compliance on multivariate analyses (p < 0.01).Conclusion: Our findings support the validity of BCIS-T to assess cognitive insight of the patients with schizophrenia. We suggest addressing the intricacies of cognitive insight beyond the traditional two-dimensional models in cross-cultural settings.

Aims.The 19-item ‘Scale Of Prodromal Symptoms’ (SOPS) and its semi-structured interview, the Structured Interview for Prodromal Symptoms (SIPS), have been developed to assess prodromes of psychosis. We assessed psychometric properties of the Italian version of the instrument.Methods.We collected socio-demographic and clinical data of 128 people seeking first-time psychiatric help in a large Roman area, either as outpatients at community facilities or as inpatients in psychiatric wards of two general hospitals. Participants were administered the Italian version of the SOPS and the 24-item Brief Psychiatric Rating Scale (BPRS). Data were analysed through Pearson's correlation and factorial analysis.Results.The English and Italian SOPS versions showed similar psychometric properties and factorial structure. The best-fit model was trifactorial, explaining 90% of total variance, and roughly corresponding to the positive, negative, and general dimensions, with disorganisation spreading over the other dimensions. Compared with the BPRS, the Italian version of the SOPS showed construct validity and convergent validity.Conclusions.The factor–structure of the Italian version of the SOPS is similar to those of the English and Spanish versions, in that the factors emerged are the same (positive, negative, and general symptoms). The scale could be used to assess at-risk people in early intervention services.

Filling out long questionnaires can be frustrating, unpleasant, and discouraging for respondents to continue. This is why shorter forms of long instruments are preferred, especially when they have comparable reliability and validity. In present study, two short forms of the Cross-cultural (Chinese) Personality Assessment Inventory (CPAI-2) were developed and validated. The items of the short forms were all selected from the 28 personality scales of the CPAI-2 based on the norm sample. Based on some priori criteria, we obtained the appropriate items and constructed the 56-item Chinese Personality Assessment Inventory (CPAI) and the 28-item CPAI. Then, we examined the factor structure of both short forms with Exploratory SEM (ESEM) and replicated the four-factor structure of the original CPAI-2, reflecting the four personality domains of Chinese people, namely, Social Potency, Dependability, Accommodation, and Interpersonal Relatedness. Further analyses with ESEM models demonstrate full measurement invariance across gender for both short forms. The results show that females score lower than males on Social Potency. In addition, these four factors of both short forms have adequate internal consistency, and the correlation patterns of the four factors, the big five personality traits, and several health-related variables are extremely similar across the two short forms, reflecting adequate and comparable criterion validity, convergent validity, and discriminant validity. Overall, the short versions of CPAI-2 are psychometrically acceptable and have practically implications for measuring Chinese personality and cross-cultural research.

Researchers are employing confirmatory factor analysis (CFA) with multitrait-multimethod (MTMM) matrices to estimate parameters representing trait, method, and error variance, as well as parameters representing the correlations among traits (or factors). This study utilizes CFA with MTMM matrices to assess the convergent validity, discriminant validity, and the presence and effects of method variance in the end-user computing satisfaction instrument (EUCSI) and the computer self-efficacy instrument (CSE). The results of the study indicate that, in these samples, the two instruments demonstrate adequate convergent and discriminant validity, but that method variance is present and accounts for a large proportion of the variance in both models. Further, the proposed factor structure of the EUCSI appears to be unstable as a result of the effects of multiple methods, while the proposed factor structure of the CSE remains stable in the presence of the methods.

Mindful Attention Awareness Scale

Purpose The principles of mindfulness have been increasingly applied in medical education for stress reduction. One of the most often used measures for mindfulness research is the Mindful Attention Awareness Scale (MAAS). The purpose of this paper is to determine the factor structure, and investigate its reliability and validity in a sample of multi-ethnic medical students in Malaysia. Design/methodology/approach In total, 590 medical students were involved in the study. After minor modification of the MAAS, a test battery including sociodemographic information, the MAAS, Subjective Happiness Scale (SHS), Satisfaction with Life Scale (SWLS), Five-facet Mindfulness Questionnaire (FFMQ), Depression, Anxiety and Stress Scale (DASS), and Perceived Stress Scale (PSS) was administered to the participants. Findings Exploratory and confirmatory factor analyses supported a one-dimensional factor structure of the MAAS. Cronbach’s α coefficient of the scale was 0.92 and in a sub-sample (n=118), it showed satisfactory temporal stability in two weeks period. There were significant positive correlations with SHS, SWLS, and four subscales of FFMQ scores (convergent validity); and negative correlations (discriminant validity) with the DASS and PSS scores (p<0.05). In another sub-sample (n=52) who participated in a four-week mindfulness-based intervention, the scale showed significant change in scores (p=0.002). Originality/value The study provided preliminary results supporting the use of the MAAS as a valid, reliable and stable factor structure of mindfulness measure among medical students in Malaysia.

Two Samples

A multitrait-multimethod analysis was performed on instructors' ratings obtained from three formats, behaviorally anchored rating scales, graphic rating scale, and mixed standard scale, for two samples of 100 undergraduate students each. The two samples were distinguished on the basis of whether the statements on the mixed-standard scale were behaviorally specific or more generic descriptions of the dimensions. The more specific mixed-standard scale yielded a greater proportion of inconsistent ratings than the less specific one. Also, convergent and discriminant validity were smaller and method variance and unexplained error were greater for the more specific mixed-standard scale. However, a more detailed examination of these effects in terms of selected average correlations indicated that some of these results were not necessarily due to the format. Relative levels of convergent validity were higher and relative levels of discriminant validity were lower than found by Dickinson and Zellinger in 1980 for faculty ratings in a professional school. Over-all, the mixed-standard scale engendered as much convergent and discriminant validity as did the other two rating formats.

Very High

A validation study of the English version of the 28-item Life Regard Index–Revised was undertaken with a sample of 91 participants from the general population. All previous studies of the Index have examined the Dutch version. The test-retest reliabilities at 8 wk. for the total Index ( r = .87), Framework ( r = .82), and Fulfillment ( r = .81) subscales were very high. Cronbach alphas were .92, .83, and .87, respectively. A significant restriction of range was observed at the high-meaning end of the scale. Factor analysis only weakly supported the theorized two-factor structure. A very high disattenuated correlation between the Framework and Fulfillment subscales was observed ( r = .94). The Index appeared to have adequate evidence supporting its concurrent and discriminant validity when compared with measures of hopelessness, spiritual well-being, and other measures of personal meaning. A significant positive association was found between the index and the Marlowe-Crowne Social Desirability Scale ( r = .38). The Index was also significantly associated with sex (women scoring higher) and marital status (divorced people scoring lower). Revisions of the English version may address the restriction of range problem by employing a 5-point rating scale, instead of the current 3-point scale, or by adding more discriminating items. Further factor-analytic studies with larger samples are needed before conclusions can be drawn regarding this scale's factor structure.
