The responsiveness of the CES-D and the SF-12 v2 MCS.

AUC: the area under a receiver operating characteristic curve. CES-D: the Center for Epidemiologic Studies Depression Scale. Cohen’s d effect size = (μFollowup- μBaseline)/σpooled. CI: confidence interval. PHQ-9: the Patient Health Questionnaire-9. SD: standard deviation. SF-12 v2 MCS: the Short Form-12 Health Survey version 2 Mental Component Summary. Standardized effect size = (μFollowup- μBaseline)/σBaseline.Standardized response mean = (μFollowup- μBaseline)/σFollowup-Baseline. Stable depressive symptoms (same PHQ-9 score). Improved depressive symptoms (reduced PHQ-9 score). Mean difference: the difference in mean change between two groups (improved depressive symptoms vs. stable/worsened depressive symptoms). Worsened depressive symptoms (increased PHQ-9 score). # Paired t-test was used. The responsiveness of the CES-D and the SF-12 v2 MCS.
