A family member of an adolescent who has expressed suicidal thoughts asks a nurse, "What factors help predict the risk of future suicide attempts?" Which response should the nurse include?

Choice A reason: Death of a spouse is a significant psychosocial stressor and a known precipitant of complicated grief, major depressive disorder, and increased suicidal ideation in bereaved adults. However, in the specific context of an adolescent, spousal bereavement is not developmentally applicable and therefore would not be the most relevant or accurate response to a family member asking about predictive risk factors for future suicide attempts in this age group. While loss can contribute to suicidal risk, death of a spouse is not considered a primary predictive risk factor for future attempts in the adolescent population. Choice B reason: Unemployment is a recognized psychosocial risk factor associated with increased rates of depression, hopelessness, and suicidal ideation in the adult population, particularly in middle-aged men. It is linked to financial stress, loss of identity, and social isolation. However, while employment-related stressors may contribute to overall suicidal risk in adults, unemployment is not considered the strongest or most evidence-based predictor of future suicide attempts, particularly in adolescents. A direct, validated predictor of repeat suicidal behavior has greater clinical utility in guiding risk assessment and response to a family's inquiry. Choice C reason: A previous suicide attempt is the single most statistically robust and clinically validated predictor of future suicide attempts and completed suicide across all age groups, including adolescents. Research in suicidology consistently demonstrates that individuals with a history of prior suicide attempts are at significantly elevated risk of repeat behavior, with studies indicating that approximately 15 to 25% of individuals who have attempted suicide will make subsequent attempts. The lethality of prior attempts, method used, intent, and circumstances of rescue are additional dimensions that inform risk stratification. This information is clinically essential and directly responds to the family member's question. Choice D reason: Polysubstance use is a well-established and clinically significant risk factor for suicidal behavior. Intoxication disinhibits impulse control, impairs judgment, increases emotional dysregulation, and can precipitate acute suicidal crises in predisposed individuals. Comorbid substance use disorders significantly elevate lifetime suicide risk. However, while polysubstance use is an important contributor to overall suicide risk and must be assessed, it does not carry the same predictive power for future suicide attempts as a previous suicide attempt itself, which is universally considered the most powerful single risk factor in validated suicide risk assessment tools such as the Columbia Suicide Severity Rating Scale (C-SSRS).
