Historical approaches to substance abuse treatment

Disease model and twelve-step programs

The disease model of addiction has long contended the maladaptive patterns of alcohol and substance use displayed by addicted individuals are the result of a lifelong disease that is biological in origin and exacerbated by environmental contingencies. This conceptualization renders the individual essentially powerless over his or her problematic behaviors and unable to remain sober by himself or herself, much as individuals with a terminal illness are unable to fight the disease by themselves without medication. Behavioral treatment, therefore, necessarily requires individuals to admit their addiction, renounce their former lifestyle, and seek a supportive social network who can help them remain sober. Such approaches are the quintessential features of Twelve-step programs, originally published in the book Alcoholics Anonymous in 1939. These approaches have met considerable amounts of criticism, coming from opponents who disapprove of the spiritual-religious orientation on both psychological and legal grounds. Nonetheless, despite this criticism, outcome studies have revealed that affiliation with twelve-step programs predicts abstinence success at 1-year follow-up for alcoholism. Different results have been reached for other drugs, with the twelve steps being less beneficial for addicts to illicit substances, and least beneficial to those addicted to the physiologically and psychologically addicting opioids, for which maintenance therapies are the gold standard of care.
Client-centered approaches

In his influential book, Client-Centered Therapy, in which he presented the client-centered approach to therapeutic change, psychologist Carl Rogers proposed there are three necessary and sufficient conditions for personal change: unconditional positive regard, accurate empathy, and genuineness. Rogers believed the presence of these three items in the therapeutic relationship could help an individual overcome any troublesome issue, including alcohol abuse. To this end, a 1957 study compared the relative effectiveness of three different psychotherapies in treating alcoholics who had been committed to a state hospital for sixty days: a therapy based on two-factor learning theory, client-centered therapy, and psychoanalytic therapy. Though the authors expected the two-factor theory to be the most effective, it actually proved to be deleterious in outcome. Surprisingly, client-centered therapy proved most effective. It has been argued, however, these findings may be attributable to the profound difference in therapist outlook between the two-factor and client-centered approaches, rather than to client-centered techniques per se. The authors note two-factor theory involves stark disapproval of the clients’ “irrational behavior” (p. 350); this notably negative outlook could explain the results.

A variation of Rogers' approach has been developed in which clients are directly responsible for determining the goals and objectives of the treatment. Known as Client-Directed Outcome-Informed therapy (CDOI), this approach has been utilized by several drug treatment programs, such as Arizona's Department of Health Services
