    Development of a computerized adaptive substance use disorder scale for screening, measurement and diagnosis - The CAT-SUD-E
    (Elsevier, 2022-03-23) Hulvershorn, Leslie A.; Adams, Zachary W.; Smoker, Michael P.; Aalsma, Matthew C.; Gibbons, Robert D.; Psychiatry, School of Medicine
    Introduction: The Computerized Adaptive Test for Substance Use Disorder (CAT-SUD), an adaptive test based on multidimensional item response theory, has been expanded to include 7 specific Diagnostic and Statistical Manual, 5th edition (DSM-5) defined SUDs. Initial testing of the new measure, the CAT-SUD expanded (CAT-SUD-E) is reported here. Methods: 275 Community-dwelling adults (ages 18-68) responded to public and social-media advertisements. Participants virtually completed both the CAT-SUD-E and the Structured Clinical Interview for DSM-5, Research Version (SCID) to assess the validity of the CAT-SUD-E in determining whether participants met criteria for specific DSM-5 SUDs. Diagnostic classifications were based on 7 SUDs, each with 5 items, for current and lifetime SUDs. Results: For SCID-based presence of any lifetime SUD, predictions based on the overall CAT-SUD-E diagnosis and severity score were AUC=0.92, 95% CI = 0.88, 0.95 for current and AUC=0.94, 95% CI = 0.91, 0.97 for lifetime. For individual diagnoses, classification accuracy for current SUDs ranged from an AUC=0.76 for alcohol to AUC=0.92 for nicotine/tobacco. Classification accuracy for lifetime SUDs ranged from an AUC=0.81 for hallucinogens to AUC=0.96 for stimulants. Median CAT-SUD-E completion time was under 4 min. Conclusions: The CAT-SUD-E quickly produces similar results as lengthy structured clinical interviews for overall SUD and substance-specific SUDs, with high precision and accuracy, through a combination of fixed-item responses for diagnostic classification and adaptive SUD severity measurement. The CAT-SUD-E harmonizes information from mental health, trauma, social support and traditional SUD items to provide a more complete characterization of SUD and provides both diagnostic classification and severity measurement.

    Recommendations for applying a multi-dimensional model of impulsive personality to diagnosis and treatment
    (BioMed Central, 2018-04-02) Um, Miji; Hershberger, Alexandra R.; Whitt, Zachary T.; Cyders, Melissa A.; Psychology, School of Science
    The UPPS-P Model of Impulsive Personality, a prominent model of impulsive personality derived from the Five Factor Model of Personality, is a multi-dimensional model of impulsive personality that consists of negative urgency, lack of premeditation, lack of perseveration, sensation seeking, and positive urgency. The UPPS-P model has highlighted the importance of separating multidimensional traits due to the specificity of these traits corresponding to different risk behaviors. The goal of the current review paper is to make recommendations on how to apply the UPPS-P Model of Impulsive Personality, to diagnosis of and treatment for psychopathology. However, despite impulsivity being one of the most frequently used criteria for a number of clinical disorders, our review of the Diagnostic and Statistical Manual for Mental Disorders-5 found that the UPPS-P traits are not well represented in the diagnostic criteria, which we propose limits inferences about etiology and treatment targets. Additionally, research has largely focused on the importance of these traits for risk models; our review of the literature applying the UPPS-P traits to treatment processes and outcomes concluded that this area is not yet well studied. Here, we propose the specific application of the UPPS-P model to improve diagnosis and increase treatment effectiveness.
