Adapting an evidence-based physical activity questionnaire for people with physical disabilities: A methodological...

Practitioners and researchers often adapt tools, practices, and programs to meet the needs of culturally diverse population groups, but do not consider populations with disability. While there is some research on guidelines for adapting evidence-based programs, there is no systematic process for adapting survey instruments. Rather than creating separate instruments for people with physical disabilities (PWD), it is critical that instruments are designed to capture data on people with and without disabilities for comparison purposes. Given the disproportionately high rates of physical inactivity and obesity in PWD, we developed a methodology to adapt an evidence-based physical activity instrument.

To create a methodology to adapt surveys to be inclusive of PWD and use the methodology to adapt an evidence-based physical activity survey.

A framework was developed to adapt a physical activity survey instrument (International Physical Activity Questionnaire, IPAQ) to be inclusive of PWD. The framework, referred to as SAVe-IT, includes five steps: Step 1) Select survey instrument to adapt; Step 2) Adapt the survey instrument; Step 3) Verify adaptations with experts; Step 4) Implement pilot test; Step 5) Test the tool to confirm reliability.

The adapted IPAQ passed review by the expert panels and the pilot test (n = 20). Assessment of test-retest reliability (n = 30) yielded strong intraclass correlation coefficients of 0.950 for the total score for the whole sample, 0.950 for PWD (n = 15) and 0.952 for people without disability (n = 15).

The SAVe-IT framework resulted in the successful adaptation of the IPAQ and can be used in populations with and without physical disabilities.
