Abstract

In an individual who seeks help or is referred to a mental health professional it is common sense and clinical practice to assume that suicidal thoughts and previous attempts constitute risk factors for imminent suicide. However, this assumption has not been supported by large, population-based longitudinal studies. The current study investigated whether reports of current suicidal ideation and a history of suicide attempts indeed increase risk for later completed suicide in a historical prospective study design. Sequential records on 89,049 young males assessed by mental health professionals were screened for suicidal ideation and a history of suicide attempts. The data were linked with death records from the Israeli Central Bureau of Statistics. Over a follow-up period ranging from 2 months to 9.8 years, 54 individuals died by suicide, constituting an average suicide rate of 6.48 per 100,000 person-years. Overall, neither reporting current suicidal ideation (without a history of suicide attempts; HR=1.29, 95% CI=0.57-2.90) nor reporting a history of suicide attempts (with or without current suicidal ideation; HR=1.67, 95% CI=0.71-3.97) were significantly associated with increased risk for later completed suicide. However, young males with a previously diagnosed psychiatric disorder who reported current suicidal ideation (HR=4.52, 95% CI=1.08-18.91) or a history of suicide attempts (HR=6.43, 95% CI=1.54-26.90) were at increased risk of death by suicide. These findings indicate that in this particular population reports of current suicidal ideation or of a history of suicide attempts are helpful in predicting future suicide only among those with a previous diagnosis of a psychiatric disorder.
