Although many substance abuse organizations offer case management services, little is known about clients' satisfaction as consumers of case management services. The purpose of this study was to evaluate consumer preferences regarding the delivery of case management services in a rural substance abuse treatment program. For this study, 120 clients (30 in each of four research conditions) were interviewed about their experiences in the Iowa Case Management Project (ICMP), a fieldbased clinical trial evaluating a strengths-based model of case management for rural clients in drug abuse treatment. A mixed-method approach evaluated clients' responses from a semistructured interview. Most clients preferred meeting with their case manager in their own home. Clients also stated that they preferred specific characteristics of case management services- namely, convenience, privacy, comfort, and accessibility. Finally, clients wanted more time with their case managers over time. Although clients in drug treatment are not often considered as consumers, we found that client satisfaction with case management services could be studied and that clients appreciated being asked about their experiences. By targeting perceived and actual barriers to meeting with case managers (e.g., availability of transportation), service utilization by clients may be increased along with overall satisfaction. Keywords: case management; client satisfaction; drug abuse treatment Over the past century, case management has been implemented with increasing numbers of clients for increasing numbers and types of problems. Originating as early as the 1860s in settlement house work with immigrants and the poor (Tahan, 1998; Weil & Karls, 1985), case management has since been applied in the behavioral health fields of mental illness (Curtis, Millman, Struening, & D'Ercole, 1998; Walsh et al., 2001), substance abuse (Heinemann, Corrigan, & Moore, 2004: Siegal et al., 1995), and co-occurring disorders treatment (Drake et al., 1998; Jerrell & Ridgely, 1999). In behavioral health, case management has been tailored for use across a myriad of settings, including rural and urban locales (Clark, Leukefeld, & Godlaski, 1999; D'Ercole, Struening, Curtis, Millman, & Morris, 1997; Hall, Carswell, Walsh, Huber, & Jampoler, 2002), emergency rooms, nursing homes, schools (Tahan, 1999), prisons (Warner & Leukefeld, 2001), community settings (Lehman, Dixon, Kernan, Deforge, & Portrado, 1997; Weisman & Lambarti, 2002), the client's home (Weisman & Lambarti, 2002), and many other locations. The rapid growth of case management has paralleled an increasing interest in strategies for cost reductions in treating addiction and mental illness (Huber, 2002; Jerrell, 1996; McLellan et al., 1999). Outpatient case management has been viewed by the health insurance industry as a cost-effective mechanism for integrating, coordinating, and advocating for individuals and groups requiring extensive health care services (Huber, 2000; Powell, 2000). The push for effective and efficient service delivery has resulted in a demand for demonstrated effectiveness of case management services. However, the case management outcome literature at present has been described as "large, rapidly expanding and full of anecdotal reports and poor quality research studies" (Holloway & Carson, 2001, p. 25). Because case management has expanded so rapidly and widely, no clear consensus has been reached regarding what case management is and what it does (Huber, 2000; Tahan, 1999). Rather, multiple definitions and models of case management are currently in use. However, at least two of these definitions of case management have direct relevance to the field of social work. Case management was defined by the interdisciplinary Case Management Society of America (CMSA) as "a collaborative process of assessment, planning, facilitation and advocacy for options and services to meet an individual's health needs through communication and available resources to promote quality cost-effective outcomes" (CMSA, 2002, p. …
