Suicide is a global public health concern. While many fewer deaths per year are attributed to suicide (800,000) than to chronic disease, estimates suggest that, for every completed suicide, an additional 30‐40 attempts are made. This equates to more than 20 million attempted suicides worldwide each year1.

While poor mental health2, low cognition3, social isolation4 and socio‐economic disadvantage5 are related to suicide risk, the predictive role of other psychosocial characteristics such as personality type is uncertain. There is a circumstantial case for selected personality types being implicated in the occurrence of suicide. Observational studies, for example, suggest that low extraversion, high neuroticism, and low conscientiousness are associated with an increased prevalence of depressive symptoms6, a determinant of suicide2. Lower conscientiousness has also been linked with an increased risk of heavy alcohol consumption7, a further risk factor for suicide8.
