LGBT youth are at elevated risk for suicide. Researchers have been looking into the risk factors for suicide in LGBT youth. Most of the studies so far have been cross-sectional; that means they only studied how things are once, at one point in time. Longitudinal studies, in contrast, measure at multiple points in time. Longitudinal studies are expensive, and risk losing track of participants, but they provide more information.
This year, the first longitudinal study of LGBT youth suicide risk factors was published. The participants were interviewed twice, a year apart. Both times, they were psychiatrically evaluated and asked about suicide attempts. They filled out questionnaires evaluating hopelessness, impulsivity, social support, gender non-conformity, age of same-sex attraction, and LGBT-related victimization.
In this sample, roughly 31.6% of the participants had attempted suicide. This is far higher than the 8% rate reported by the CDC. Seven variables were associated with previous suicide attempts: hopelessness, impulsivity, LGBT-related victimization, low family support, being younger when first feeling same-sex attraction (for LGB youth), and symptoms of either depression or conduct disorder. That is, the more hopeless or impulsive the youth, the more likely it is that they have previously made a suicide attempt. Gender non-conforming behavior and peer support did not seem to affect suicide risk. When it came to predicting future suicide attempts, the best predictor was previous suicide attempts. Youth who had previously attempted suicide had a 10 times greater risk of another attempt compared to those who hadn’t attempted suicide.
As always, these results should be accepted with caution. For example, this study did not find that gender non-conforming behavior was associated with suicidality. This is in contrast to other studies which did find an association. This study’s participants may not be representative of the population. They also had a small (ish) sample: 237 participants; 21 were transgender, and 13 had attempted suicide. Small sample sizes can limit a study’s ability to detect statistical significance. Gender non-conforming behavior may actually be associated with suicidality, but this study may not have had a large enough sample to detect it.
For me, this study brings up the question: How do we prevent suicide attempts in our LGBT youth who have already attempted suicide? They’re the most at risk for future attempts, according to this study. I don’t have a solid answer; neither do the researchers. But they do say that “The current ﬁndings underscore the need for increased prevention efforts and speciﬁcally point to the value of targeting youth who have made a prior attempt and who acknowledge their same-sex attractions at younger ages.”
