Reliability and validity of the Turkish executive function performance test in people with stroke

Area of Science:

• Neuroscience
• Rehabilitation Medicine
• Psychometrics

Background:

• Executive function deficits are common after stroke, impacting daily living.
• The Executive Function Performance Test (EFPT) assesses these functions in everyday tasks.
• Validating the Turkish EFPT is crucial for its use in Turkish stroke populations.

Purpose of the Study:

• To evaluate the reliability and validity of the Turkish version of the EFPT.
• To determine if the Turkish EFPT can accurately measure executive function in stroke patients.
• To support its use in clinical practice and research for stroke rehabilitation.

Main Methods:

• The study included 72 inpatient stroke individuals.
• Internal consistency, inter-rater reliability, and convergent/divergent validity were analyzed.
• Correlations with MMSE, FIM, and SIS were assessed.

Main Results:

• The Turkish EFPT showed excellent internal consistency (Cronbach's alpha = 0.92).
• Inter-rater reliability was very good (0.99).
• High correlation with MMSE and significant correlations with FIM and SIS supported validity.

Conclusions:

• The Turkish EFPT is a reliable and valid instrument for assessing executive function in stroke survivors.
• It can guide the determination of assistance levels and intervention planning in stroke rehabilitation.
• This provides preliminary evidence for the EFPT's utility in Turkish clinical settings.
