Note. BMI = Body Mass Index; ED (EDEQ) = Eating Disorder pathology (Eating Disorder Examination Questionnaire); PD (K-10) = Psychological Distress (Kessler Psychological Distress Scale); PHQoL (SF-12) = Physical Health-Related Quality of Life (Medical outcomes study short-form); MHQoL (SF-12) = Mental Health-Related Quality of Life (Medical outcomes study short-form). The final model included invariant predictive paths, which explains why the non-standardized coefficients (b) are invariant across time periods. Conversely, the standardized coefficients (ß) are expressed in standard deviation units and are thus a function of the variances of latent constructs on which no constraints were imposed, and thus differ slightly across time periods.
