Berona J, et al. - In the present study, researchers sought to characterize histories of self-injurious thoughts and behaviors (SITBs) among high-risk lesbian, gay, bisexual, and transgender (LGBT) youth and to investigate prospective relationships with suicidal behavior. They assessed 285 youth (41.8% LGBT) ages 13 to 25 years receiving psychiatric emergency department (ED) services for postdischarge suicidal behavior via 4-month phone interviews and 12-month chart reviews. Higher likelihood to have prior psychiatric ED visits and hospitalizations, more frequent past week suicide ideation, and more severe nonsuicidal self-injury (NSSI) were evident among LGBT participants. Stratified survival analyses were performed to recognize predictors of time to suicidal behavior postdischarge. For LGBT youth, the final model incorporated past week suicide ideation and past month NSSI episodes. The final model for non-LGBT youth involved the number of lifetime NSSI methods and the use of a highly lethal suicide attempt method. LGBT youth were overrepresented and had more severe histories of SITBs in this sample of youth. Outcomes here suggest that assessment of both lifetime and recent factors (ie, past week and month) is important, especially for LGBT youth.
