Anhedonia and suicide: a 6.5-yr. follow-up study of patients hospitalised for a suicide attempt.
This was a prospective follow-up study of suicidal patients to assess the association of anhedonia, depression, and completed suicides. Survival analysis as well as Cox's regression makes it possible to weigh the influence of variables. A cohort of 106 patients (81 women, 25 men, M age=33 yr., SD=9.9) admitted to medical or surgical departments after a suicide attempt was followed during a 6.5-yr. mean observation period. In total, 6.7% of patients completed suicide. High proportion of male subjects (71.4%) and low anhedonia, assessed on the Physical Anhedonia Scale, decreased survival time of the cohort and characterized subjects who deceased by suicide. These results suggested that the people who completed suicide were characterized by low anhedonia. Further research is needed on people who attempt suicide and present with specific psychiatric diagnoses.
