Description

Depression was assessed with a 15-item depressive symptomatology screening test that was developed and used previously in Thailand (Thai Department of Mental Health, 2004). These questions were asked about problems that had bothered participants in the past week (e.g., feeling depressed most of the time; feelings of hopelessness or worthlessness; loss of self-confidence), with response categories from 0 (not at all) to 3 (usually [5-7 days a week]). A summative composite scale was developed, with a range of 0 to 45 and an excellent internal consistency (Cronbach’s alpha = 0.91).
