Abstract
This study examined suicide attempts (SAs), interrupted SAs, and aborted SAs and their cross-sectional and longitudinal associations with suicide-related correlates among high-risk active duty service members. Service members receiving suicide-related treatment completed measures at baseline (N = 1,044) and a 3-month follow-up (n = 758). Multivariate analysis of variance and regression models were used to evaluate differences between SA groups (SAs, interrupted and/or aborted SAs, no SAs) in baseline suicide-related correlates (suicidal thoughts, thwarted belongingness, anxiety sensitivity, insomnia symptoms, alcohol use, hopelessness, and posttraumatic stress disorder [PTSD] symptoms) and severity of suicidal thoughts and presence of SAs at follow-up. Results revealed that service members with interrupted and/or aborted SAs (and no prior SAs) reported significantly more severe baseline PTSD hyperarousal symptoms and were more likely to report an SA at follow-up, compared with service members who had prior SAs. Study findings highlight the importance of considering interrupted and aborted SAs when evaluating suicide risk among high-risk service members.
