Abstract

Objective: No evidence-based intervention effectively reduces cannabis use in young adults with psychosis (YAP). To generate hypotheses about why, a scoping review was conducted to synthesize evidence about motivations for cannabis use and reduction/cessation for YAP and the psychosocial interventions trialed to identify possible gaps between motivations and interventive strategies. Methods: A systematic literature search was conducted in December, 2022. Reviews of titles and abstracts (N = 3,216) and full-texts (n = 136) resulted in 46 articles. Results: YAP use cannabis for pleasure, to reduce dysphoria, and for social and recreational reasons; motivations for cessation include insight about cannabis-psychosis interactions, incompatibility with goals and social roles, and support from social networks. Interventions with at least minimal evidence of efficacy include motivational interviewing, cognitive-behavioral strategies, and family skills training. Conclusions: Authors recommend additional research on mechanisms of change and motivational enhancement therapy, behavioral activation, and family-based skills interventions matched to YAP motivations for use/cessation.

摘要

目的：没有基于证据的干预措施能有效减少患有精神病（YAP）的年轻人使用大麻。为了产生关于原因的假设，进行了范围界定审查，以综合有关大麻使用动机和减少/停止 YAP 的证据，以及尝试的社会心理干预措施，以确定动机和干预策略之间可能存在的差距。方法：于 2022 年 12 月进行了系统文献检索。对标题和摘要 ( N ​​ = 3,216) 以及全文 ( n  = 136) 的评论得出了 46 篇文章。结果：YAP 使用大麻是为了愉悦、减少烦躁感以及社交和娱乐原因；戒烟的动机包括对大麻与精神病相互作用的了解、与目标和社会角色的不相容以及来自社交网络的支持。至少具有最低限度有效性证据的干预措施包括动机访谈、认知行为策略和家庭技能培训。结论：作者建议对改变机制和动机增强疗法、行为激活以及与 YAP 使用/停止动机相匹配的基于家庭的技能干预进行更多研究。
