This multi-site project extended course dissemination of the 10-session Behavioral Management of Auditory Hallucinations Course to U.S. Department of Veterans Affairs (VA) mental health outpatient settings. The VA Quality Enhancement Research Initiative (QUERI) model and Rogers' theory of diffusion of innovations served as the theoretical framework. The course was taught to mental health professionals using teleconferencing, electronic media, and monthly conference calls across 24 VA mental health outpatient sites. Twenty course leaders provided feedback. One hundred percent reported being better able to communicate with patients about their voices and 96% reported improved understanding of the voice-hearing experience. Thirty-three course participants provided feedback. Ninety-four percent would recommend the course, 85% reported being better able to communicate with staff about their voices, and 66% reported being better able to manage their voices. Facilitators and barriers to course implementation are described.
