Objective: To examine whether the "Short QUestionnaire to ASsess Health-enhancing physical activity" (SQUASH) and the "Injuries and Physical Activity in the Netherlands" questionnaire ("Ongevallen en Bewegen in Nederland," OBiN) were valid in assessing adherence to physical activity (PA) guidelines.

Study design and setting: Participants (N=187) aged 20-69 years were categorized as "inactive," "semiactive," or "norm-active" according to the Dutch PA, the American College of Sports Medicine (ACSM), and the combined guideline (adhering to either or both of two other guidelines) by the questionnaires and a combined heart rate monitor and accelerometer (Actiheart). Percentage of exact agreement and maximum disagreement (difference of two categories) for the categorization between questionnaires and Actiheart was calculated.

Results: The SQUASH had a significant higher agreement than the OBiN for the Dutch PA (SQUASH: 78%, OBiN: 46%; P<0.01) and combined guideline (SQUASH: 84%, OBiN: 55%; P<0.01). Both questionnaires had a low agreement regarding the ACSM guideline (SQUASH: 37%, OBiN: 34%; P=0.45). The SQUASH had a significant higher maximum disagreement than the OBiN for this guideline (SQUASH: 19.8%, OBiN 8%; P<0.01).

Conclusion: The SQUASH was a more valid measure than the OBiN for categorizing adults according to the Dutch PA and the combined guideline. Both questionnaires failed to correctly categorize adults according to the ACSM guideline.
