This study is an educational evaluation of participants (N = 50) in a four-day immersion training program funded by the National Institute of Alcohol Abuse and Alcoholism. Using a pretest-posttest design, clinical social work faculty participants showed statistically significant (p < .001) improvement in overall alcohol and other drug-related knowledge (Baseline: Mean[SD] = 8.75 [2.44]; Post-Intervention: Mean[SD] = 13.88[1.96], Cohen's d = -2.16) in the domains of screening/assessment, brief intervention, medication-assisted treatment, and recovery and relapse prevention. Corresponding increases were also observed for faculty confidence in teaching clinical skills related to alcohol and other drug screening, assessment, and treatment.
