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

Abstract

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.
