Cross-Cultural Adaptation of Executive Function Performance Test (EFPT): ACOSMIN Systematic Review

Psychometrics plays a crucial role in cross-cultural research, necessitating the adaptation of scales for measuring health status. As the Executive Function Performance Test measures functional cognition and can be helpful in medical, rehabilitation, and research settings, this review aims to methodologically review cross-culturally adapted versions of the Executive Function Performance Test using the COSMIN checklist.

The present systematic review was conducted based on the COSMIN methodology. After searching PubMed, Scopus, Google Scholar, and Web of Science with keywords ranging from July 2024, seven articles were selected for a thorough methodological review matching the review objectives.

The outcomes revealed that cultural adaptation has similar phases with a few differences. The most frequently reported forms of reliability were interrater reliability and internal consistency, while some variations in validity assessment were found.

Proper cross-cultural adaptation requires steps of translation, cultural adaptation, and assessing validity and reliability. Since the tool does not provide adequate psychometric data, using it in the clinical field and research would be questionable. To adapt the Executive Function Performance Test to different cultures and languages, and also to measure its validity and reliability across various diseases that have not been previously assessed, further research is needed, following the steps outlined in this review.
