Conclusion
Thai-SAD provides sociodemographic and psychosocial data for a group of Thais experiencing new or recurrent episodes of unipolar depression. The unique aspect of this study is that it collected data regarding psychosocial variables, which may act as predictors for recurrence or relapse of depression. Some psychosocial variables, eg, a high perception of stress score, may predict a relapse. Firm conclusions cannot be reached as yet; however, because the complete data set is not yet available, the data here represents a baseline. Our intention is to address this shortfall in a subsequent study.
