Multicenter Study
The Pain Belief Screening Instrument (PBSI): predictive validity for disability status in persistent musculoskeletal pain.
To evaluate the predictive validity of a screening instrument measuring disability, self-efficacy, fear of movement and catastrophizing, for disability status in patients with musculoskeletal pain in primary health care physical therapy. Development over time of pain-related disability, pain intensity, self-reported work capacity and overall daily function for subgroups of patients was also investigated. ⋯ The predictive validity of the PBSI for disability was confirmed. In clinical use the PBSI could serve as a mean to obtain supplementary and clinically useful information.
