A criterion-referenced multidimensional job-related model prediction capability to perform occupations among persons with chronic pain

{\it Objective:} The purpose of this prospective study was an exploration of the construct of the criterion-referenced multidimensional job-related model (CMVA) aimed for predicting patients' with chronic pain capability to perform occupations. {\it Methods:} The study samples were 1) participants ( $n=84$ ) who at present were not performing employed work (median sick-listing period 12 months) because of chronic pain and 2) participants ( $n =$ 104) who at present were performing employed work at least 20 hours of a workweek. The participants had experiences of 40 different occupations classified into five of the occupational categories of Jist's Enhanced Dictionary of Occupational Titles. Data were collected through ten assessment instruments and a structured interview, comprising 54 variables and 465 items. Data were analyzed using multiple regression with forward entering of variables. {\it Results:} The CMVA model (Adjusted $R^2 0.777, F (4, 183) = 164.067; p<0.001$ ) was able to explain 78% CMVA contained the aspects; ``the work demands-variable, the person-variable of work life values, the environment-variable of social support and the two occupational performances-variables; self-perceived capability to perform work tasks/the simulated work tasks''. {\it Conclusions:} The construct of CMVA was robust suggesting that among persons with chronic pain, the predictors focusing on their capability to perform occupations are of great importance.
