Life satisfaction and suicidal attempts among persons with schizophrenia

The relationship between subjective quality of life (QOL) and suicide attempts in patients with schizophrenia has been understudied. The current study tested the hypothesis that QOL is negatively associated with a history of suicidality of patients with schizophrenia. QOL, as measured by the Quality of Life Enjoyment and Satisfaction Questionnaire (Q-LES-Q), was investigated in 227 inpatients with DSM-IV diagnosis of schizophrenia with and without a lifetime history of suicide attempts. The statistical analysis included analysis of variance (ANOVA), t tests, and analysis of covariance (ANCOVA). The patients who had attempted suicide multiple times were less satisfied with regard to a larger number of life domains than the nonattempters and the single attempters. The differences in QOL remained significant after adjusting for psychiatric history and current psychopathology variables, e.g., age of onset of the disorder, number and length of hospitalizations, and positive, negative, and depressive symptoms. Dissatisfaction with QOL in general and with reference to four specific domains was associated with repeated suicide attempts. Clinicians should include QOL in the evaluation of patients with schizophrenia that are suspected to be suicidal.
