A Validity and Reliability Study of the Turkish Adaptation of the Executive Function Performance Test in Individuals with Schizophrenia

The aim of our study is to examine the validity and reliability of the EFPT by adapting it into Turkish. Individuals were included 131 (n = 105 schizophrenia, n = 26 healthy). The Cronbach α reliability coefficient of the EFPT was found to be 0.827. In terms of criterion validity, a significant correlation was observed between the EFPT results and Trail Making Test A and B scores (r = 0.588 p = 0.001, r = 0.608 p = 0.001). In terms of construct validity, it was seen that the EFPT has the ability to identify different constructs (p < 0.05). According to the results, the Turkish version of the EFPT is a reliable and valid scale.
