The purpose of this study is to use self-reported data from adolescents as the foundation for a statistical screening process of suicidal behavior. Latent Class Analysis (LCA) is used to study patterns of suicidal behavior among adolescents and by extension, the development of evidence-based behavioral profiles of those adolescents identified as having suicidal-related behaviors. Suicidal behavior variables in the Youth Risk Behavior Survey (YRBS) ask about specific actions related to suicide ideation, planning, attempts and injury, but it is the underlying construct of "suicidal behavior" that is the ultimate question of interest. LCA allows for the development of evidence-based behavioral profiles to be developed for the use of screening for suicidal behavior through behavioral surrogates. Results identify a set of behaviors that are consistently identified over the years to be significantly associated to suicidal behavior and include trauma, violence, substance abuse, sexual behavior, issues related to weight, and depression.
