Validation of Beck Cognitive Insight Scale - Arabic version in a Tunisian sample.

OBJECTIVES: Cognitive insight reflects cognitive processes concerning patients' capacity of distancing from and reevaluation of anomalous beliefs and misinterpretations. The purpose of the present study was to examine the reliability and validity of the Arabic version of the Beck Cognitive Insight Scale. METHODS: The English language version of the Beck Cognitive Insight Scale was translated into Literary Arabic. A total of 150 patients with and without psychosis completed the Arabic version of Beck Cognitive Insight Scale and additional evaluations to assess psychopathology. Psychometric properties including content validity, construct validity using confirmatory factor analysis, discriminant validity and reliability were assessed for this translated measure. RESULTS: Our results revealed that the Arabic version of the Beck Cognitive Insight Scale showed adequate psychometric properties that permitone to assess impairments of cognitive insight in patients with psychosis and in patients without psychotic features. The fit indices of the confirmatory factor analysis supported the validity of the two-factor structure corresponding to self-reflectiveness and self-certainty subscales. Psychotic patients were significantly more confident in their beliefs compared with non-psychotic patients. Scores of self-certainty were significantly higher in psychotic patients. Cronbach's alpha reliability indicator of the Arabic version was equal to 0.60. Cronbach's alpha coefficients were 0.60 and 0.53 for the self-reflectiveness sub-scale and the self-certainty sub-scale, respectively. CONCLUSIONS: The Arabic version of the Beck Cognitive Insight Scale is valid and reliable for the assessment of cognitive insight. It may improve the detection and the prevention of impairments in cognitive insight.

Predictors of sleep quality in medical students during COVID-19 confinement.

OBJECTIVES: We aimed to assess sleep quality of Tunisian medical students during home confinement due to the COVID-19 pandemic, and to analyze the relationship between sleep quality and sociodemographic, clinical, confinement-related and psychological variables. METHODS: A correlational cross-sectional study was conducted from April 11th to May 3rd 2020. Medical students who have been in home confinement and who accepted to participate in an online survey were targeted. Sociodemographic data, clinical variables, and data related to home confinement were collected. Participants also completed Pittsburgh Sleep Quality Index, Depression, Anxiety and Stress Scale and Beck Hopelessness Scale. RESULTS: Results showed a high prevalence of poor sleepers among medical students (72.5%) with poor subjective sleep quality, increased sleep latency, sleep disturbances and daytime dysfunction. Multiple regression analysis revealed that family history of suicide attempts, tobacco use, perception of home confinement and reduced physical activity during home confinement significantly contributed to poor sleep quality. Among the psychological variables, anxiety and hopelessness significantly contributed to poor sleep quality in medical students during home confinement. CONCLUSIONS: Results revealed a high prevalence of poor sleep quality in medical students who have been in home confinement due to the COVID-19 pandemic. Except family history of suicide attempts, factors that significantly contributed to poor sleep quality were modifiable factors. Sleep quality and sleep parameters need to be assessed in this particular population and adequate measures aiming to promote quality of sleep need to be enhanced, given the crucial regenerative, homeostatic and psychological roles of sleep.
