Background/Purpose
Self-report questionnaires and performance-based tests correlate moderately in measuring activity limitations, indicating that they measure different aspects. Self-reports measure mainly how patients think they perform an activity, and is influenced by pain, fatigue or situations they are referring to. This may lead to cross-cultural differences. Performance-based tests measure an artificial situation, is resource-intensive and burdensome for patients. To overcome these drawbacks we developed and tested a pilot version of an Animated Activity Questionnaire (AAQ), which demonstrated some promising features[1]. The aim of this study was to develop a computerized Animated Activity Questionnaire (AAQ) to assess activity limitations in patients with hip/ knee osteoarthritis and preliminary testing of its validity and reliability.
Methods
Based on the pilot version, International Classifications of Functioning core set for osteoarthritis, focus groups of patients, and existing measurement instruments, the AAQ was developed. In 482 patients correlations were calculated between the Animated Activity Questionnaire (AAQ) and self-reported Hip disability and Knee injury Osteoarthritis Outcome physical functioning score. In addition internal consistency was calculated. In 65/482 patients also correlations with performance based tests ( Stair Climbing Test , Timed Up and Go test, and the 30 second Chair Stand Test) were calculated. Test-retest reliability was assessed by repeated scoring in 56/482 patients.
Results
The Animated Activity Questionnaire (AAQ) includes animated videos of 17 basic daily activities with four levels of increasing difficulty (check the following link for two examples: http://kmin-vumc.nl/_14_0.html). Patients were asked to select the video that best matched their own performance. Cronbach’s alpha was 0.95. Correlation with self-reported physical functioning scores was high (0.72). The AAQ correlated moderately with the performance based tests (0.49, 0.44, and 0.57, respectively). Correlations of the AAQ score with pain was lower (0.51) than the correlation of the self-reported physical functioning score with pain (0.75). For test-retest reliability, a Intraclass Correlation Coefficient of 0.97 (95% Confidence Interval 0.93-0.98) was found.
Conclusion A computerized Animated Activity Questionnaire (AAQ) was developed showing a high internal consistency and excellent test-retest reliability. Content validity was considered good, and construct validity is supported by high correlations with self-reported physical functioning and moderate correlations with performance-based tests. The AAQ seems to be less influenced by pain compared with self-reported physical functioning. Since the AAQ needs no reading ability or translation, it has potential for international use. Continuing research will focus on construct validity and cross-cultural validity.
