Description
Summary:•Suicide planning and suicidal ideation increased the odds of engaging in same day NSSI.•Neither cannabis nor alcohol use independently predicted the odds of same day NSSI.•The co-occurrence of alcohol and cannabis use increased the odds of same day NSSI. This study examined the trajectories of alcohol use, cannabis use, suicide planning (SP), and nonsuicidal self-injury (NSSI) prior to hospitalization and examined the role of alcohol and cannabis use, independently and jointly, in predicting NSSI on a daily level and over time. Participants included 71 adolescents hospitalized for suicide risk (75% female; 25% male; Mage = 15.79). All participants drank alcohol at least once in the prior 90-days. We conducted mixed effect models to assess the trajectories of alcohol use, cannabis use, and NSSI over the 90-days prior hospitalization. To test the effect of SP, alcohol use, and cannabis use on NSSI, we conducted logistic random effect models, while controlling for demographics. SP (OR = 4.47, p
