Consenting eligible patients will be randomly assigned to TDM or the lower intensity intervention of usual care. For those patients assigned to usual care, the physician will administer further evaluations and treatment as he/she sees fit. For those assigned to TDM, the primary care provider remains the agent of treatment, but a Behavioral Health Specialist (BHS) is made available to: maintain regularly scheduled telephone contact, develop a treatment plan, monitor treatment effectiveness, assess and encourage treatment adherence, and offer support and education. The role of the health specialist is defined by a treatment manual that adheres to the recommendations of VA practice guidelines. TDM is based on a chronic care model of treatment and includes a minimum of three BAI sessions. The health specialist will communicate assessment information with the PCP in order to coordinate treatment decisions.
