Mental health, risk behaviors, and social life factors in relation to adolescents' suicide ideation, plans and attempt

ObjectiveThis study investigated differences in mental health and well-being, risk behaviors, and social life factors among adolescents who experienced different forms of suicidality.MethodsWe examined 18-years-olds in the Danish National Birth Cohort (N = 47,852). Suicidality was defined with mutually exclusive categories ranging from no suicidality, self-reported suicide ideation, plans, and attempt as well as hospital-recorded suicide attempt. The proportion of adolescents with self-reported poor mental health and well-being, risk behaviors, and social life factors were compared across forms of suicidality. Sample weights were applied.ResultsDepressive symptoms were reported by 14% (95% CI 13%;14%) of girls with no suicidality, 44% (95% CI 43%;45%) of girls with suicide ideation, and 68% (95% CI 65%;72%) 66% (95% CI 60%;72%) of girls with self-reported suicide attempt or hospital-recorded suicide attempt respectively. Among boys, depressive symptoms were reported by 5% (95% CI 4%;5%) of those with no suicidality, 27% (95% CI 26%;28%) of those with suicide ideation, and 51% (95% CI 45%;57%) and 40% (95% CI 22%;58%) of those with self-reported suicide attempt or hospital-recorded suicide attempt respectively. Likewise, other aspects of poor mental health and well-being gradually increased relative with more severe forms of suicidality, while no notable differences were identified between adolescents with self-reported and hospital-recorded suicide attempt. Similar tendencies were observed for risk behaviors and social life factors.ConclusionThese findings suggest that adolescents with suicidality, including the large proportion with suicide ideation only, faces challenges across several parameters of mental health and well-being, risk behavior, and social life factors. This emphasizes the need for community-based interventions to identify and support the large group of adolescents experiencing both more and less severe forms of suicidality. Clinicians should prioritize comprehensive psychiatric intervention to address the complex needs of suicidal adolescents effectively.
