Abstract
OBJECTIVE: To investigate the validity of proxy respondent reports of stressful life events, social support and suicidal behavior among individuals who attempted suicide. METHOD: Subjects were 80 psychiatric in-patients admitted following a suicide attempt. Data based on structured interviews with proxy respondents were compared with data based on interviews with subjects (gold standard). RESULTS: Specificity was higher than sensitivity across life event categories, and agreement was substantial for public and observable events (e.g. parent's death) but lower for more ambiguous events. Proxies were good judges of subject reports of frequency of social interaction but not perceived emotional support. Proxies were good judges of past history of suicide attempts and level of suicidal intent. CONCLUSION: Results support proxy-based data on suicidal behavior and certain aspects of social support and stressful life events in research of suicidal behavior in this age group, with potential implications for interpreting postmortem research of completed suicide.
