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

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.

The current work strives to put the concurrent validity and reliability of the Persian version of MIC-SR to the test.

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.

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.

The Persian version of the MIC-SR demonstrated satisfying psychometric properties that can assess awareness of cognitive impairments in patients with schizophrenia.
