Impulsivity is a multifaceted construct that plays a prominent role in substance use disorder (SUD). The UPPS-P model distinguishes five impulsivity components (positive urgency, negative urgency, lack of perseverance, lack of premeditation, and sensation seeking). This study aimed to explore the structure of the UPPS-P in patients hospitalized for SUDs and to investigate the relationship between the dimensions of impulsivity and clinical variables.
Inpatients of a residential detoxification service ( = 125) were recruited. A confirmatory factor analysis was performed, and associations were assessed between the components of impulsivity and clinical indexes.
The factor analysis supported a model of impulsivity with five interrelated latent variables. Good internal consistency was found. External validity was supported by relationships with psychological difficulties. Multiple correlations (Kendall) suggested that, except for its sensation-seeking component, impulsivity is a significant risk factor for both the severity of addictive problems and their comorbidities.
This study provides further evidence in favor of the 5-dimensional model of impulsivity. It highlights impulsivity as a transdiagnostic risk factor that should be considered in the management of SUD.
冲动性是一个多维度的概念，在物质使用障碍（SUD）中起着重要作用。UPPS-P模型区分了五个冲动性成分（积极紧迫性、消极紧迫性、缺乏坚持性、缺乏预谋性和寻求刺激）。本研究旨在探讨因SUD住院患者中UPPS-P的结构，并研究冲动性维度与临床变量之间的关系。
招募了一家住院戒毒服务机构的125名住院患者。进行了验证性因素分析，并评估了冲动性成分与临床指标之间的关联。
因素分析支持了一个具有五个相互关联的潜在变量的冲动性模型。发现具有良好的内部一致性。与心理困难的关系支持了外部效度。多重相关性（肯德尔相关性）表明，除了其寻求刺激成分外，冲动性是成瘾问题严重程度及其共病的一个重要风险因素。
本研究为冲动性的五维度模型提供了进一步的证据。它强调冲动性是一个跨诊断的风险因素，在SUD的管理中应予以考虑。
