“…These problems may cause distress and trigger relapse even among persons who successfully reduce their substance use (Friedmann, Saitz, & Samet, 1998;McLellan & Weisner, 1996), and delivery of comprehensive services to address these issues has been shown to improve functioning, treatment retention, and outcomes (McLellan, Arndt, Metzger, Woody, & O'Brien, 1993;McLellan, Grisson, et al, 1993;McLellan & Weisner, 1996;McLellan et al, 1998). Despite their importance to quality substance abuse treatment (Leshner, 1999;Leukefeld, Pickens, & Schuster, 1992), the availability of comprehensive services declined from 1980to 1990(D'Aunno & Vaughn, 1995Etheridge, Craddock, Dunteman, & Hubbard, 1995;McLellan & Weisner, 1996;Widman, Platt, Lidz, Mathis, & Metzger, 1997). The current study examined whether the downward trend in the availability of comprehensive services in outpatient substance abuse treatment programs continued in the 1990s, while accounting for characteristics of these programs and their clientele.…”
