Key result
Turkish Executive Function Performance Test demonstrates excellent reliability and high convergent validity with the MMSE.
Why the study?
The validity and reliability of the Turkish Executive Function Performance Test in people with stroke had not been established.
Is the Turkish Executive Function Performance Test a valid and reliable tool for assessing executive function in people with stroke?

Is the Turkish Executive Function Performance Test a valid and reliable tool for assessing executive function in people with stroke?
Effect estimate: Cronbach's alpha 0.92; r = -0.732 for MMSE
p-value: p=<0.001
The Turkish version of the Executive Function Performance Test is a valid and reliable tool for assessing executive function in stroke patients during rehabilitation.
May support Turkish EFPT in stroke assessments; leaves open larger validation before routine use.
The Executive Function Performance Test (EFPT) is a performance-based test designed to assess parameters of executive function in instrumental activities of daily living. This study aimed to examine the validity and reliability of the Turkish EFPT in people with stroke. The present study was carried out on 72 individuals with stroke (32 female, 40 male) undergoing inpatient care at Etlik City Hospital. Analyses of internal consistency, inter-rater reliability, and convergent and divergent validity were carried out. The mean age of the participants was 62.81 ± 12.33 years and the mean time since stroke was 19.96 ± 39.81 months. According to the reliability analysis, the Cronbach’s alpha level of the Turkish EFPT was found to be excellent (0.92). The inter-rater reliability analysis showed a very good agreement (0.99). A significant and high correlation was found between the MMSE (r = −0.732; p < .001) and Turkish EFPT in convergent validity analysis. In divergent validity analysis, significant but weaker correlations were found between the Turkish EFPT and the FIM (r = −0.499; p < .001) and SIS (r = −0.381; p < .031). This study may provide preliminary evidence for the validity and reliability of the Turkish EFPT in individuals with stroke. The EFPT appears to be able to facilitate effective assessment of executive function in stroke rehabilitation, to help determine the level of assistance required for functional activities, and to assist in planning suitable interventions.

Gürbüz et al. (2025) conducted a cross-sectional in Stroke (n=72). Turkish Executive Function Performance Test (EFPT) vs. MMSE, FIM, and SIS was evaluated on Internal consistency, inter-rater reliability, and convergent/divergent validity (Cronbach's alpha 0.92; r = -0.732 for MMSE, p=<0.001). The Turkish Executive Function Performance Test demonstrated excellent internal consistency (Cronbach's alpha 0.92), very good inter-rater reliability (0.99), and high convergent validity with the MMSE (r=-0.732, p<0.001).
