Abstract |
Many individuals who die by suicide or attempt suicide have no pre-existing psychiatric record. In these cases determination of the presence of mental illness at the time of the suicidal act depends on diagnostic interviews with different informants, but the reliability of such interviews is unknown. To address this issue, the current study from northern China conducted independent diagnostic interviews (by different psychiatrists) with a co-resident family member and another associate of 151 suicide decedents, with 120 individuals who attempted suicide, and with two proxy informants for each suicide attempter. In the suicide decedent group, 56% of interviews with family members and 50% with other associates resulted in one or more psychiatric diagnosis; the concordance (kappa) of these two respondents for the presence of any current psychiatric disorder, any mood disorder and any other psychiatric disorder were 0.35, 0.32 and 0.41, respectively. In the suicide attempt group, 47% of interviewers with suicide attempters, 31% with family members, and 15% with other associates resulted in a psychiatric diagnosis; the concordance for any current psychiatric disorder, any mood disorder and any other psychiatric disorder between the interview with the suicide attempter and the combined result of the two separate proxy informant interviews were 0.31, 0.34 and 0.39, respectively. We conclude that the concordance of the presence and type of psychiatric diagnosis of individuals with suicidal behavior based on independent structured interviews by psychiatrists with different informants is low to fair and that using multiple informants will increase the identification of psychiatric disorders.
