J Nerv Ment Dis. 2003 Jul;191(7):450-7. doi: 10.1097/01.NMD.0000081613.03157.D9.

Abstract

This study examined the reliability and validity of the instruments as used in the psychological autopsy method in China. With data from 130 informants on 66 completed suicides and 130 informants on 66 normal community controls and 66 controls themselves, the validity was examined by comparing the responses of informants and the responses (gold standards) of the target participants in the control group. All the tested instruments were shown to be reliable, and proxy respondents were generally good judges of targets' suicidal intention, social support, depression, life events, personality traits, and mental disorders. Additionally, interrater reliabilities of the five interviewers were very good on selected scales. This study has laid a partial foundation for future psychological autopsy projects to be held in Chinese culture.
