Persons with severe mental illnesses (SMI) often lack access to effective treatments. The authors describe the Implementing Evidence-Based Practices (EBPs) Project, designed to increase access for people with SMI to empirically supported interventions. The EBP Project aims to improve access through development of standardized implementation packages, created in collaboration with different stakeholders, including clinicians, consumers, family members, clinical supervisors, program leaders, and mental health authorities. The background and philosophy of the EBP Project are described, including the six EBPs identified for initial package development: collaborative psychopharmacology, assertive community treatment, family psychoeducation, supported employment, illness management and recovery skills, and integrated dual disorders treatment. The components of the implementation packages are described as well as the planned phases of the project. Improving access to EBPs for consumers with SMI may enhance outcomes in a cost-effective manner, helping them pursue their personal recovery goals with the support of professionals, family, and friends.
