Investigation of the Validity and Reliability of the Turkish Adaptation of Allen Cognitive Level Screen-5 (ACLS-5) with Individuals with Schizophrenia.

This study aimed to explore validity and reliability of the Allen Cognitive Level Screen-5(ACLS-5) in individuals with schizophrenia. One hundred and twenty individuals (n=60 with schizophrenia; n=60 healthy individuals) were participants. Test-retest reliability, discriminant validity and construct validity analysis were performed. According to the analysis of construct validity, there was a significant correlation between ACLS-5 and Social Functioning Scale (r=0.382-0.487, p<0.05) and between ACLS-5 and Wisconsin Card Sorting Test (r=0.257-0.557, p<0.01). The ACLS-5 has shown strong test-retest reliability with an intra-class correlation coefficient (ICC = 0.93) and discriminant validity (z=7.065, p<0.001). This study provides preliminary evidence for the validity and reliability of the Turkish version of the ACLS-5. [ABSTRACT FROM AUTHOR]
