Reliability and Validity of Culturally Adapted Executive Function Performance Test for Koreans with Stroke

Area of Science:

• Neuroscience
• Rehabilitation Medicine
• Psychology

Background:

• Existing Executive Function Performance Test (EFPT) is culturally unsuitable for Asian populations.
• Evaluating real-life executive function is crucial for stroke survivors.
• Need for a culturally adapted assessment tool for Korean stroke patients.

Purpose of the Study:

• Develop and standardize the Executive Function Performance Test for Koreans (EFPT-K).
• Verify the reliability and validity of EFPT-K in the Korean stroke population.

Main Methods:

• Cultural adaptation of EFPT through translation, back-translation, and expert review.
• Assessed inter-rater reliability and internal consistency in 34 stroke patients.
• Validated EFPT-K against Trail-Making Test, Stroop Test, Digit Span Test, and AMPS.

Main Results:

• EFPT-K demonstrated high inter-rater reliability and internal consistency.
• Criterion validity was supported by correlations with most neuropsychological tests and specific AMPS components.
• Digits backward test did not correlate with EFPT-K total score.

Conclusions:

• EFPT-K is a reliable and valid tool for assessing executive function in Korean stroke patients' daily lives.
• EFPT-K can be a valuable sample for adapting executive function assessments in other Asian cultures.
• The tool facilitates a thorough evaluation of executive function in real-world tasks for stroke survivors.
