Assessing the construct validity of the Baecke Questionnaire in individuals with knee osteoarthritis

Background & Aims

The Baecke Habitual Physical Activity Questionnaire (BHPAQ) and the International Physical Activity Questionnaire (IPAQ) are prominent tools for evaluating physical activity levels across various domains. Despite the widespread use, when tested for concurrent validity, the IPAQ and PASE, show little correlation with objective measures. Conversely, the BHPAQ has not been examined for validity in people with KOA, despite having been shown to be valid in measuring Physical Activity Level (PAL) in women with hip dysfunction. Therefore, the purpose of this study is to evaluate the BHPAQ’s construct validity in KOA patients.

Methods

A cross-sectional study conducted in accordance with the guidelines set forth by Strengthening the Reporting of Observational Studies in Epidemiology (STROBE). The COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) checklist was used to choose the 80 participants in the sample. Participants satisfied the American College of Rheumatology’s (ACR) KOA diagnosis criteria. During the first session, participants completed three performance-based functional tests and demographic information was gathered. The activPALTM device was used, and the BHPAQ was given. Participants returned the activPALTM in a follow-up visit after a 7-day break.

Results

Of the 80 participants in the final sample, 40 (or 50%) were women, and their average age was 59.5 ± 8.40 years. To determine construct validity, the Spearman’s correlation coefficient was computed. Only two out of five (40%) of the predefined hypotheses were confirmed by the BHPAQ.

Conclusions

In conclusion, the BHPAQ might be helpful in certain circumstances, but its limitations in PAL evaluation in KOA patients highlight the need for a flexible and tailored approach to measurement. The pursuit of a more thorough understanding of the relationship between physical activity and knee osteoarthritis will undoubtedly facilitate the creation of interventions and tactics meant to optimize the overall health and well-being of people coping with this prevalent condition.
