AB  - Given the growing number of fatalities associated with the use of multiple types 
      of drugs, there is an urgent need for a tool that allows clinicians and 
      researchers to quickly assess diverse reasons for substance use. Here, we sought 
      to validate the Motivational Inventory Underlying Substance Engagement (MI-USE), 
      a new measure that assesses motivations for use across different types of 
      substances. Participants were 538 adults ages 18-60 (48% women) who reported 
      substance use problems and past-year drug or alcohol use. Analyses were conducted 
      to discover and validate the factor structure of the MI-USE and evaluate its 
      construct validity. A 30-item model best fit the MI-USE, with one General Factor 
      capturing overall motivation to engage in substance use and eight motive-specific 
      factors that indexed unique motivations for substance use: Emotional Coping 
      (relief from unpleasant emotions), Pleasure-Seeking (feel pleasurable or exciting 
      emotions and sensations), Dependence Severity (avoid withdrawal and cravings), 
      Expansion (enhance self-insight and spirituality), Social Coping (increase 
      confidence and attractiveness), Advantage (gain a physical or mental advantage), 
      Physical Coping (relief from unpleasant bodily sensations), and Sleep (mitigate 
      sleep problems). Evaluation of the measure's construct validity and internal 
      consistency support the chosen model and interpretation of the motive-specific 
      factors. Results provide initial validation of the MI-USE as a reliable and valid 
      tool for assessing diverse substance use motivations. It improves upon existing 
      measures by allowing clinicians and researchers to simultaneously evaluate 
      motivations for multiple forms of substance use, which facilitates personalized 
      treatment planning and research on polysubstance use.
