Description
Sexual and gender minority (SGM) youth have annual prevalence rates of sucide attempts of 29%, up to 4.6 times higher than that of other youth. We propose to test whether prevention programs that target suicide directly, or a range of factors that increase risk for suicide (internalizing symptoms, alcohol abuse, drug use, externalizing, bullying and interpersonal violence) reduce suicide risk for youth in general, and whether SGM youth benefit more or less from such programs. Working with a broad network of prevention trials researchers, we have received permission to obtain individual-level data from several dozen randomized prevention trials involving thousands of participants. All trials include direct or surrogate measures of suicide risk, and information about SGM status. Although all trials have tested and reported intervention impact on specific behavioral health outcomes, few have tested specific impact on SGM youth, given that such youth make up a relatively small proportion of the samples in each study. Our work and that of others indicates that combining data across trials will provide far greater power for testing several key hypotheses about impact on suicide risk, and whether SGM youth receive differential benefit from these interventions. We will use methods developed in our prior work to combine these datasets, and utilize findings from two measurement development studies of SGM and non-SGM youth suicide risk to guide advanced psychometric analyses for harmonizing outcome measures and developing a common index of suicide risk. We will apply integrative data analysis (IDA) methods that account for missing data to test three sets of hypotheses.
Aim 1. Test whether different types of interventions decrease risk for suicidal thought and behavior in general populations of youth. We hypothesize that preventive programs reduce risk for suicidality regardless of primary target. We will use IDA to test this hypothesis on the full dataset.
Aim 2. Test whethe
