Abstract

OBJECTIVES:

We analyzed Rhode Island's 2007 Youth Risk Behavior Survey (YRBS) data to investigate suicide patterns and their association with suicide risk predictors among public high school students.

METHODS:

We used latent class regression analysis of Rhode Island's 2007 YRBS data (from a random sample of 2210 public high school students) to model latent classes of suicide risk and identify predictors of latent class membership.

RESULTS:

Four latent classes of suicide risk were modeled and predictors were associated with each: class 1 (emotionally healthy, 74%); class 2 (considered and planned suicide, 14%) was associated with being female, having low grades, being gay/lesbian/bisexual/unsure, feeling unsafe at school, having experienced forced sexual intercourse, and self-perceived overweight; class 3 (attempted suicide, 6%) was associated with speaking a language other than English at home, being gay/lesbian/bisexual/unsure, feeling unsafe at school, and forced sexual intercourse; and class 4 (planned and attempted suicide, 6%) was associated with the previously mentioned predictors and with being in 9th or 10th grade and currently smoking.

CONCLUSIONS:

A single model characterized and quantified 4 patterns of suicide risk among adolescents and identified predictors for 3 at-risk classes. Interventions for high-risk youths may help prevent adolescent suicides.
