The International Classification of Human Functioning Disability and Health (ICF) provides insight into functional health status in patients with whiplash-associated disorders (WAD). In the assessment of functional limitations in patients with WAD, there are several condition-specific questionnaires available. Estimation of the true relationship between the separate constructs of the ICF is only possible if the items of the salient questionnaires measure exactly the constructs of interest, while not simultaneously measuring other constructs of the model. This study aimed to develop a condition specific and clinically relevant and usable instrument for patients with WAD that measures activity limitations and participation restrictions, as defined by the ICF framework. ⋯ The whiplash activity and participation list tends to measure clinically relevant activity limitations and participation restrictions in WAD patients.
