Translation, Validity, and Reliability of the Persian Version of “Keele Assessment of Participation” (P-KAP) Questionnaire among Community-Dwelling Older Adults

Abstract

Introduction The Keele Assessment of Participation (KAP) is a clear, short, valid, and reliable questionnaire developed specifically to evaluate participation restrictions. KAP has been translated into various languages. This study aimed to translate and determine the psychometric properties of the “Keele Assessment of Participation” in healthy community-dwelling elderly people. Methods A forward/backward translation procedure was used for translating the KAP questionnaire into Persian. Older adults (N = 165) aged 60 and over participated. Content and face validity were evaluated. Convergent validity was assessed by evaluating the correlation between KAP and the short-form 36 (SF-36), and community integration measure (CIM). Internal consistency and test-retest reliability (N = 110) were determined by assessing the Kappa and Cronbach’s alpha. Results The content and face validity of the Persian version of KAP (P-KAP) were appropriately reported as good. The P-KAP demonstrated acceptable internal consistency (α = 0.77) and test-retest reliability (Kappa = 0.82). The correlation between the P-KAP, the CIM, and the SF-36 total score was moderate and respectively −0.416 and −0.468 (p < 0.0001). Discussion The results of the current study found P-KAP to be an acceptable, reliable, and valid instrument.
