Özet

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 alpha 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.
