Validation of the Persian Version of Measure of Insight into Cognition Self-report (MIC-SR) in Patients with Schizophrenia

Abstract

Background: Measure of insight into cognition self-report (MIC-SR) has been designed for the assessment of insight into cognitive deficits in schizophrenia, focusing on the areas with known impairment, including memory, problem solving, and attention. Objectives: The current work strives to put the concurrent validity and reliability of the Persian version of MIC-SR to the test. Methods: The standard forward-backward method was utilized for translating the MIC-SR from English to Persian. In total, 66 individuals received the Persian version of the MIC-SR (33 schizophrenia patients), the interview-based cognition assessment (Schizophrenia Cognition Rating Scale (SCoRS)), and a standardized performance-based cognitive battery (the brief assessment of cognition in schizophrenia (BACS)). Coronbach’s alpha was used for the calculation of internal consistency, while intercorrelations among the MIC-SR subscales were calculated as well. Then, Pearson correlations were calculated between the MIC-SR subscales and SCoRS and BACS for the purpose of examining the validity. Results: The Cronbach’s alpha value obtained for the Persian MIC-SR was 0.83. The entirety of Persian MIC-SR measures was considerably correlated with the SCoRS patient’s rating. Moreover, considerable correlations were found among the WHO-quality of life and Persian MIC-SR subscales of attention and problem solving. However, none of the correlations between the BACS subscales and MIC-SR were significant. Conclusions: The Persian version of the MIC-SR demonstrated satisfying psychometric properties that can assess awareness of cognitive impairments in patients with schizophrenia.
