From: Importance of remission and residual somatic symptoms in health-related quality of life among outpatients with major depressive disorder: a cross-sectional study

  1. MDD = major depressive disorder; DS = depression subscale of the depression and somatic symptoms scale (DSSS); SS = somatic subscale of the DSSS.
  2. Stepwise regression analysis using the full set of variables of the DSSS adjusted by age and sex:
  3. Model 1: QoL (EQ-5D index score|New) = a + b1(DS score) + b2(SS score) + b3(Bech) + b4(Age) + b5(Sex).
  4. Model 2: QoL (EQ-5D index score|Remitted) = a + b1(DS score) + b2(SS score) + b3(Age) + b4(Sex).
  5. Model 3: QoL (EQ-5D index score|Non-remitted) = a + b1(SS score) + b2(Gibbons) + b3(Age) + b4(Sex).
