WebTo determine whether taking depression into consideration could improve the predictive value of a multidimensional index, we converted the SDS score into a 5-point scale, ranging from 0 to 4, representing 25–39, 40–49, 50–59, 60–69, and ≥70, respectively. The rationale for setting up this scale was based on the severity of depression.
