In the United States, one in five adults are impacted by some form of mental illness in any given year, but only about 40% of individuals seek professional mental health support. While occupational therapists (OT) may work with individuals with mental illness to improve social skills, activities of daily living (ADLs), instrumental ADLs, and neurocognitive interventions, research suggests there is not enough emphasis on this content in professional OT education. Mental Health First Aid (MHFA) training is designed to educate individuals on mental illness, including how to recognize signs and symptoms and how to support individuals experiencing a concern or crisis. This study examined changes in stigma, knowledge, and confidence among OT students following MHFA training, and compared to a control group. Results demonstrated improved knowledge and confidence within the experimental group, highlighting the impact of MHFA training in this population.
