Key: HRQoL: Health-Related Quality of Life; MCS: Mental Component Summary; PCS: Physical Component Summary; SE: Standard error; Wt.: Weighted; IPTW: the Inverse Probability Treatment Weights.

Follow-up PCS and MCS scores refer to scores not adjusted by IPTW.

Based on 1692 adults aged over 21, reported having diabetes and depression in the baseline year and year and alive in the baseline and subsequent year and followed for one year. Values for the missing categories of the body mass index and smoking status variables are not presented. The p-values were derived from the F-tests between depression treatment categories and the physical and mental health component summary scores
