Participants were recruited from outpatients in psychiatric clinic and clinical psychological clinic, and inpatients residing in the mental health hospital.
Most of the healthy volunteers were recruited from the advertisement posters in community and medical college.
There are two steps for screening. Firstly, each person was asked to complete the BDI (Beck Depression Inventory,21-items) to evaluate the depressive symptoms. Individuals with scores less than 13 and more than 20 were enrolled for this study.
Secondly, each individual has to be taken for a structural diagnostic interview (MINI-International Neuropsychiatric Interview, M.I.N.I.6.0.) in order to diagnosis current disorder and evaluate suicide risk by a psychiatrist who had already clinical consistency training.
