In consultation with international content experts, we have created asynchronous training courses in one-at-a-time therapy and Stepped Care 2.0. Mental healthcare providers (e.g., social workers, psychologists, nurses, counselors) working in partnering provinces (i.e., NL, NB & PEI) are eligible to receive training in one-at-a-time therapy and Stepped Care 2.0 commencing in June 2021. Our team will evaluate the impact of this training on: 1) provider knowledge in one-at-a-time therapy and stepped care 2.0; and 2) clinical decision making.
