  1. R 2 adj = variance in the dependent variable accounted for by the predictor variable(s), adjusting for statistical shrinkage; SF-12 = Medical Outcomes Study Short Form; PCS = Physical Component Summary Scale; EDQOL = Eating Disorders Quality of Life Questionnaire; EDE = Eating Disorders Examination (global scale).
