Substance use disorders and borderline personality disorders (BPD) often co-occur and may be concurrently treated by Dialectical Behavior Therapy (DBT). However, there is limited information on how drug use and suicidal ideation may interact in the daily lives of individuals receiving DBT treatment.
This study examined the DBT diary cards of 47 individuals in a community mental health center's partial hospital and intensive outpatient program. Multilevel modeling techniques were used to examine the moderating effects of BPD symptom severity on the relationship between same day, 1-, 2-, and 3-day lagged drug use and suicidal ideation.
Results indicated a significant relationship between same-day, 1-day lagged, 2-day lagged drug use and suicidal ideation. BPD was a moderator for the relationship between 1-day lagged drug use and suicidal ideation.
Limitations of the study include the measure for BPD symptom severity was only collected pretreatment and the results are likely limited to the effects of cannabis use on suicidal ideation. Clinicians may need to consider the prolonged effects of drug use on suicidal ideation when conducting chain analyses on suicidal behaviors.
物质使用障碍和边缘型人格障碍(BPD)常常同时发生,可能同时接受辩证行为疗法(DBT)治疗。然而,关于药物使用和自杀意念如何在接受 DBT 治疗的个体的日常生活中相互作用的信息有限。
本研究对社区心理健康中心的部分医院和强化门诊计划中的 47 名个体的 DBT 日记卡进行了研究。使用多层建模技术来检验 BPD 症状严重程度对当天、1 天、2 天和 3 天滞后药物使用与自杀意念之间关系的调节作用。
结果表明,当天、1 天滞后和 2 天滞后的药物使用与自杀意念之间存在显著关系。BPD 是 1 天滞后药物使用与自杀意念之间关系的调节因素。
本研究的局限性包括 BPD 症状严重程度的测量仅在治疗前收集,结果可能仅限于大麻使用对自杀意念的影响。当对自杀行为进行连锁分析时,临床医生可能需要考虑药物使用对自杀意念的长期影响。
