The bioSocial Cognitive Theory (bSCT) hypothesizes two pathways linking dimensions of impulsivity to substance use. The first predicts that the association between reward sensitivity and substance use is mediated by positive outcome expectancies. The second predicts that the relationship between rash impulsiveness and substance use is mediated by refusal self-efficacy. This model has received empirical support in studies of alcohol use. The present research provides the first application of bSCT to a cannabis treatment population and aims to extend its utility to understanding cannabis use and severity of dependence.
273 patients referred for cannabis treatment completed a clinical assessment that contained measures of interest.
A public hospital alcohol and drug clinic.
The Sensitivity to Reward Scale, Dysfunctional Impulsivity Scale, Cannabis Expectancy Questionnaire, Cannabis Refusal Self-Efficacy Questionnaire and Severity of Dependence Scale-Cannabis were completed, along with measures of cannabis consumption.
The bSCT model provided a good fit to the data for cannabis use and severity of dependence outcomes. The association between reward sensitivity and each cannabis outcome was fully mediated by positive cannabis expectancies and cannabis refusal self-efficacy. The relationship between rash impulsiveness and each cannabis outcome was fully mediated by cannabis refusal self-efficacy.
Findings support the application of the bSCT model to cannabis use and dependence severity and highlight the important role of social cognitive mechanisms in understanding the association between impulsivity traits and these outcomes. The differential association of impulsivity traits to social cognition may assist targeted treatment efforts.
生物社会认知理论(bSCT)假设冲动维度与物质使用之间存在两种关联途径。第一种预测是,奖励敏感性与物质使用之间的关联受积极的预期结果所中介。第二种预测是,冲动性与物质使用之间的关系受拒绝自我效能感所中介。该模型在酒精使用的研究中得到了实证支持。本研究首次将 bSCT 应用于大麻治疗人群,并旨在扩展其对理解大麻使用和依赖严重程度的应用。
273 名被转介到大麻治疗的患者完成了包含感兴趣测量的临床评估。
一家公立医院的酒精和毒品诊所。
完成了奖励敏感性量表、功能失调性冲动量表、大麻期望问卷、大麻拒绝自我效能问卷和大麻依赖严重程度量表,以及大麻消费的测量。
bSCT 模型为大麻使用和依赖严重程度的结果提供了很好的拟合。奖励敏感性与每个大麻结果之间的关联完全受积极的大麻期望和大麻拒绝自我效能感所中介。冲动性与每个大麻结果之间的关系完全受大麻拒绝自我效能感所中介。
研究结果支持将 bSCT 模型应用于大麻使用和依赖严重程度,并强调了社会认知机制在理解冲动特质与这些结果之间关联的重要作用。冲动特质与社会认知的不同关联可能有助于有针对性的治疗努力。
