Provider stigma toward people who have substance use disorders (SUDs) may be a barrier to effective treatment delivery. The purpose of this study was to measure provider stigma among healthcare professionals-in-training and determine whether stigma levels were associated with professional decision making. A sample of 240 participants were recruited from the following academic programs at a large university in the southeastern United States: Nursing, Social Work, Counseling, Marriage and Family Therapy, and Psychology. Through an online, anonymous survey, provider stigma and other constructs were measured. The participants were also asked to make two hypothetical professional decisions: one regarding their choice to provide treatment for an SUD patient and the other regarding their likelihood of attending a professional development event (i.e., conference session) on the topic of SUDs. Results showed that self-reported stigma toward patients with SUDs was associated with a reduced likelihood of choosing to provide treatment for a patient with SUD (compared to patients with other conditions) and a reduced likelihood of attending SUD training at an upcoming conference (compared to other conference topics). Results have potential implications for the development of training programs for pre-professional healthcare trainees.
