Chronic musculoskeletal pain and functional status in juvenile rheumatoid arthritis: an empirical model

An empirical model is proposed and tested on variables hypothesized to influence functional status in 23 children with juvenile rheumatoid arthritis experiencing chronic musculoskeletal pain. Child psychological adjustment, family psychosocial environment, chronic musculoskeletal pain, and disease activity were entered into multiple regression analyses to statistically predict 4 functional status criterion variables: activities of daily living (ADL), activities involvement, school functioning, and social functioning. Predictor variable relationships were found for all 4 functional status criterion variables, suggesting initial support for this empirical model of functional status in children with juvenile rheumatoid arthritis experiencing chronic musculoskeletal pain.
