Self-perceived confidence of health professions students at one university in caring for adults with intellectual disability (ID) was examined via an electronic survey using the Therapy Confidence Scale - Intellectual Disabilities (TCS-ID). A stepwise multiple regression of data collected from 232 completed surveys revealed that prior training and prior experience were predictors of TCS-ID total score. Adults with ID experience healthcare disparities due, in part, to poor provider communication and a lack of confidence. Results from this novel study suggest that opportunities for experiential learning and training with people with ID are important considerations for health professions curricula. Further research is needed for generalizability of results.
