The study was supported by a dedicated grant from the Australian Research Council. We would like to thank Dr. Angelo de Gioannis and Dr. Hugh Simpson (psychiatrists) who made the clinical diagnoses for the Queensland suicide cases and controls. We also acknowledge the clinical interviewers Davina Donovan, Kwong Chan, Maedean Brown, and Trudi Little. We would also like to thank Annette Altendorf for assisting with statistical analyses.

Personality traits were examined using the NEO Five-Factor Inventory–Revised in an Australian psychological autopsy study involving 259 suicide deaths and 181 sudden death controls aged 35 years and over. Interviews included the Structured Clinical Interview for DSM-IV to determine the presence of psychiatric disorder. Personality traits of suicide deaths differed significantly from those of controls, scoring higher in the Neuroticism and Openness to Experience domains and lower on the Agreeableness and Extraversion domains. These findings varied with the presence of psychiatric disorder and by age. High Neuroticism scores were the most consistent finding in people who died by suicide, although these scores decreased in older suicides.
