Activities and participation play important roles in the maintenance of healthy aging. The maintenance of these factors optimizes social life to increase the quality of life with aging. However, there is a lack of questionnaires in Turkish to evaluate activity and participation among older people. This study translated and cross-culturally adapted the Oxford Participation and Activities Questionnaire (Ox-PAQ) into Turkish and investigated its psychometric properties in the older adult population.
The Turkish version of the Ox-PAQ was produced after a translation and back-translation process. The Ox-PAQ was administered to 230 and 60 individuals for construct validity and reliability analyses, respectively. To assess the test-retest reliability of the Turkish Ox-PAQ, the questionnaire was reapplied 7 days after the first interview. Cronbach’s alpha (α) was used to evaluate the internal consistency. The Ox-PAQ was compared to the Short Form-12 and the Katz Index of Independence in Activities of Daily Living Scale to determine its validity.
The Turkish Ox-PAQ showed excellent internal consistency (α=0.98) and test-retest reliability (intraclass correlation coefficient=0.98, 0.96, and 0.97 for the subscales of routine activity level, social engagement, and emotional well-being, respectively). In the validity analysis, factor analysis demonstrated a probable structure of the three factors that together explained 66.35% of the total variance. The Turkish Ox-PAQ was correlated with the other comparison measures used in this study.
The Turkish Ox-PAQ is a reliable and valid questionnaire to evaluate the participation and activity levels of older people (Clinical Trial Number: NCT04368754).
