Incidence and predictors of suicidal behaviors in a longitudinal sample of young Adolescents.
This analysis examines 1-year transition probabilities and baseline predictors for suicidal behaviors in young adolescents.
Adolescents from a two-stage, community-based longitudinal study were classified into suicidal behavior categories (attempt, plan, ideation, and none) for baseline and follow-up years.
Transition probabilities for movement among categories were calculated, and polytomous logistic regression analysis was used to examine predictors of suicidal behaviors.
Among those with no suicidal behaviors at baseline, 1-year incidence rates were 1.3% for attempts and 1.7% each for plans and ideation.
Increasing family cohesion was protective for suicide attempts (odds ratio [OR]=0.9).
Female subjects were more likely than males to report plans (OR=8.9) and ideation (OR=4.1).
Increasing impulsivity (OR=2.3), prior suicidal behavior (OR=10.6), and undesirable life events (OR=1.1) were significant predictors of plans.
While there are a number of predictors of suicidal behaviors, the false-positive rate is high.
Focusing on proximal risk factors, particularly stressors in adolescent development, may overlook the fundamental role of underlying mental disorder and familial factors-both biological and environmental.
Suicide and suicidal behaviors are the result of a constellation of adverse factors requiring a range of interventions for prevention.
