The purpose of this study was to identify the best set of variables measured at in-hospital interview to predict perceived pain-related impairment of function at three week follow-up in 361 hospitalized adult patients with pain (173 males, 188 females; mean age 48.3 years). / Multiple regression analyses were performed on a subset of data from a large prospective pain prevalence study. Three models were developed to predict perceived overall function, physical function and psychological function on a training sample (n = 252) and tested for reliability on a cross validation sample (n = 109). Independent variables measured at the in-hospital interview included sociodemographic, cognitive, physical and psychological variables. The dependent function variables were assessed at three week follow-up. / Overall functional impairment at three weeks was best predicted by perceived overall function, pain quality, nonsurgical pain, and hospital stay of one to three months in the past year. Impairment of physical function was predicted by perceived physical function, pain quality, one-to-three month hospital stay during the past year, and pain duration of greater than three months. Impairment of psychological function was best predicted by perceived psychological function, pain quality, and nonsurgical pain. The models explained 22%, 19% and 23% of the variance respectively. Statistical reliability was established for each model through the process of cross validation.
