Explained variance (Nagelkerke R²=0.544).

See Method section of text for measures that were utilized. Model without SF-12 Mental Component Scale because of the high correlation (.67) with distress score (4DSQ). Fast recovery group is reference group for multinomial regression analysis. Cutoff points for dichotomous variables are defined by median score of the total population. The variables of paid work, no sports participation, recurrent complaints, nonmusculoskeletal comorbidity, low health locus of control, and distress (4DSQ) were removed from the model.
