Suicide attempters, suicide ideators, and non-ideators: Differences in protective factors

Background: Suicide ideation is a prerequisite for suicide attempts. However, the majority of ideators will never act on their thoughts. It is therefore crucial to understand factors that differentiate those who consider suicide from those who make suicide attempts. Aim: Our aim was to investigate the role of protective factors in differentiating non-ideators, suicide ideators, and suicide attempters. Method: Inpatients without suicide ideation (n = 32) were compared with inpatients with current suicide ideation (n = 37) and with inpatients with current suicide ideation and a lifetime history of suicide attempts (n = 26) regarding positive mental health, self-esteem, trust in higher guidance, social support, and reasons for living. Results: Non-ideators reported more positive mental health, social support, reasons for living, and self-esteem than suicide ideators and suicide attempters did. No group differences were found regarding trust in higher guidance. Suicide ideators and suicide attempters did not differ regarding any of the study variables. Limitations: Results stem from a cross-sectional study of suicide attempts; thus, neither directionality nor generalizability to fatal suicide attempts can be determined. Conclusion: Various protective factors are best characterized to distinguish ideators from nonsuicidal inpatients. However, the same variables seem to offer no information about the difference between ideators and attempters.
