Abstract

Objective: We sought to evaluate an expanded and adapted version of the Treatment Self-Regulation Questionnaire (TSRQ) to assess the internalization continuum of motivation per self-determination theory (SDT) for responsible cannabis use and cannabis protective behavioural strategies (PBS).

Methods and measures: We recruited 1,196 college students (Study 1) and 1,409 adults (Study 2) who reported past-month cannabis to complete online surveys; a random sample of 501 adults in Study 2 completed a follow-up survey one month later.

Results: We found support for a 3-factor exploratory structural equation model of a 26-item TSRQ representing autonomous motivation, controlled motivation, and amotivation. Associations of the TSRQ with cannabis outcomes were consistent with SDT such that greater autonomous motivation was associated with more frequent cannabis PBS use (e.g. 'Limit use to weekends'). In contrast, greater controlled motivation and amotivation were associated with more negative cannabis-related consequences and more severe cannabis use. Differences emerged for instructions referencing responsible cannabis use versus cannabis PBS in Study 1.

Conclusions: The results support the use of the expanded and adapted TSRQ to assess motivations per SDT for cannabis harm reduction behaviours. These findings warrant replication and suggest that responsible cannabis use is conceptualized to be distinct from cannabis PBS.

一个自决理论视角的动机大麻相关的危害减少行为：扩大和适应治疗自我调节问卷的评估。

目的：我们试图评估治疗自我调节问卷（TSRQ）的扩展和改编版本，以评估根据自我决定理论（SDT）对负责任的大麻使用和大麻保护行为策略（PBS）的动机内化连续体。方法和措施：我们招募了1,196名大学生（研究1）和1,409名成年人（研究2），他们报告了过去一个月的大麻使用情况，以完成在线调查；研究2中随机抽取的501名成年人在一个月后完成了一项后续调查。结果：我们发现了代表自主动机、控制动机和动机的26项TSRQ的三因素探索性结构方程模型的支持。TSRQ与大麻结果的关联与SDT一致，因此更大的自主动机与更频繁的大麻PBS使用有关(例如。“只在周末使用”)。相比之下，更大的可控动机和动机与更多的负面大麻相关后果和更严重的大麻使用有关。在研究1中，关于负责任的大麻使用和大麻PBS的说明出现了差异。结论：结果支持使用扩展和调整的TSRQ来评估每个SDT减少大麻危害行为的动机。这些发现值得重复，并表明负责任的大麻使用的概念与大麻PBS不同。
