DDPs entering VA outpatient mental health treatment received either standard (N=145) or intensive (N=142) referral. Standard referral consisted essentially of the counselor recommending DFG participation. The keys to intensive referral were a DFG orientation and the counselor facilitating direct contact between the patient and a DFG member, and following up on recommendations for mutual help. Patients were followed at six months (80%), one year (81%) and two years (80%) to determine whether intensive referral resulted in more DFG and SFG participation, and better substance use and psychiatric outcomes.
