Traditional addiction therapy programs funded by health and pension insurers typically focus on the goal of absolute abstinence. As a result, these approaches risk excluding a variety of changes in clients and labeling otherwise cooperative individuals as unmotivated. Rudolf Klein advocates for a greater consideration of the self-set goals of those struggling with addiction: abstinence, controlled drinking, reduced drinking, and normal drinking. He presents four complete case studies showcasing practical systemic techniques and methods throughout the different phases of therapy. In parallel, 24 typical challenges faced by addiction therapists are described in detail from a systemic perspective. Topics discussed include considerations regarding therapy goals, motivational work, relapses, coercive contexts, and existential issues.
