“…Both retrospective and longitudinal studies have documented that high levels of social support are related to better treatment outcomes (Billings & Moos, 1982;Captain, 1989;Fagan & Mauss, 1986;Grey, Osborn, & Reznikoff, 1986;Joe & Simpson, 1983;MacDonald, 1987;Moberg, Krause, & Klien, 1982;Moos, Bromet, Tsu, & Moos, 1978;Rhoads, 1983;Rosenberg, 1983;Rychtarik, Carstensen, Alford, Schlundt, & Scoot, 1988). As a result, several treatment programs have directed their efforts toward helping addicts restructure their social relationships, and success of these efforts has been documented (Daley, 1989;Galanter, 1987;Kosten, Jalali, Hogan, & Kleber, 1983 1984). Research has emphasized the importance of participating in selfhelp groups (e.g., AA, NA) for building supportive relationships in the recovery process and ending destructive relationships (Galanter, Casteneda, & Salamon, 1987;McLatchie & Lomp, 1988;Sheeren, 1987;Thurstin, Alfano, & Nerviano, 1987;Williams, Stout, & Erickson, 1986).…”
