Psychometric Properties of the Chinese Version of the Oxford Participation and Activities Questionnaire in People with Stroke.

Abstract

The Oxford Participation and Activities Questionnaire was developed for generic use in the assessment of participation and activity levels. However, it is not available in Chinese and has not been tested in the stroke population. The Oxford Participation and Activities Questionnaire was translated into Chinese and culturally adapted. Its psychometric properties were examined in 100 people with stroke. The participation and activity levels of people with stroke and healthy people were also compared. Content validity and internal consistency (Cronbach's α = 0.86-0.91) were excellent. The test-retest reliability (intraclass correlation coefficient = 0.91-0.94) was also satisfactory. The standard error of the measurement was 4.10-5.31, and the minimal detectable change was 11.37-14.71. Convergent and divergent validity were supported by hypothesis testing. The instrument had a five-factor structure without a ceiling effect. Its routine activity and social engagement scores discriminated people with stroke from healthy people. In conclusion, the Chinese version of the Oxford Participation and Activities Questionnaire is reliable and valid for assessing participation and activity levels in the stroke population.
