Background

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.

Methods

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.

Results

SP (OR = 4.47, p < 0.001) and suicide ideation (SI) (OR = 10.09, p < 0.001) significantly increased the odds of engaging in NSSI. Neither cannabis nor alcohol use independently predicted the odds of engaging in NSSI, however, the co-occurrence of alcohol and cannabis use increased the odds of engaging in NSSI on a given day (OR = 30.5, p < 0.05).

Conclusions

Study findings extend current knowledge about the longitudinal and day-to-day relationships between alcohol and cannabis use and NSSI. Results underscore the importance of developing interventions that address polysubstance use among suicidal adolescents engaging in NSSI.

青少年住院患者酒精和大麻使用与非自杀性自伤之间的关系:检查精神病院住院前 90 天

背景

本研究检查了住院前酒精使用、大麻使用、自杀计划 (SP) 和非自杀性自伤 (NSSI) 的轨迹,并检查了酒精和大麻使用在日常预测 NSSI 中的作用,独立和联合并且随着时间的推移。

方法

参与者包括 71 名因自杀风险住院的青少年(75% 女性;25% 男性;M年龄 = 15.79)。所有参与者在之前的 90 天内至少饮酒一次。我们进行了混合效应模型来评估住院前 90 天内酒精使用、大麻使用和 NSSI 的轨迹。为了测试 SP、酒精使用和大麻使用对 NSSI 的影响,我们进行了逻辑随机效应模型,同时控制了人口统计数据。

结果

SP (OR = 4.47, p < 0.001) 和自杀意念 (SI) (OR = 10.09, p < 0.001) 显着增加了参与 NSSI 的几率。大麻和酒精使用都不能独立预测参与 NSSI 的几率,但是,酒精和大麻使用的共同发生增加了在特定日期参与 NSSI 的几率(OR = 30.5,p < 0.05)。

结论

研究结果扩展了当前关于酒精和大麻使用与 NSSI 之间纵向和日常关系的知识。结果强调了制定干预措施以解决参与 NSSI 的有自杀倾向的青少年使用多种物质的重要性。
