 This proposed project is designed to evaluate and provide direct evidence for the clinical effectiveness of the Bounce Back: Reclaim your Health BB project currently implemented in 17 communities in British Columbia BC. BB is an innovative mental health service in the health care system designed to help patients participate in their own care by teaching them the sufficient and necessary skills to manage their moods. This BB program, led by the Canadian Mental Health Associations BC Division, offers mental health support to primary care patients suffering from mild to moderate depression. BB is a low intensity, high capacity program, based on cognitive behaviour therapy CBT self-help materials Overcoming Depression, Low Mood and Anxiety: A five areas approach OD - comprising psycho-educational DVD and self-help mood improvement workbook. The content of these self-help materials was adapted to a BC context for the BB program. In addition, in order to best meet the needs of BC primary care patients, this new mental health service is delivered to patients in their own homes and patients use of the OD self-help materials is supported via trained telephone coaches. Telephone coaches are non-specialists trained and monitored by a registered psychologist. Coaching enables patients to engage with and get the most out of the materials. The advantages of telephone coaching include privacy, accessibility, and convenience, especially for those patients living in rural areas and can not access treatment due to geographic barriers; those who do not seek treatment due to stigma; or those who are coping with chronic physical illness and multiple medical appointments. There is only indirect support for the effectiveness of the BB program. Thus, this proposed project is designed to evaluate and provide direct evidence of the effectiveness of the BB program.
