Background: 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.
Method: 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.
Results: 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.
Conclusion: 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.

Objectives: The purpose of this study was to provide insights into which patient-level characteristics are associated with a positive treatment response among patients whose primary drug of choice was a psychostimulant with a particular emphasis on understanding the impact of age at first use and co-occurring psychiatric comorbidities.
Methods: We used a cross-sectional study design and the 2019 US Treatment Episode Data Set: Discharges (n = 167 802) to identify outpatient treatment episodes for which the primary drug of choice was a psychostimulant. We defined a positive treatment response as (1) a reduction in drug use between treatment admission and discharge or (2) no use at both admission and discharge.
