 The primary objective of our proposed research is to provide direct evidence of the effectiveness of the BB program, and, in particular, the telephone coaching component. The investigators will test: 1 whether the BB program is more effective than general practitioner GP treatment-as-usual TAU; and 2 whether BBs positive results can be attributed to the telephone coaching component, as this component is associated with the most significant costs of the program. A secondary objective is to assess the cost-effectiveness of such telephone support.
