Each of the subsections of the book deals with a specific focus of the modified therapeutic community: mental health and human services; criminal justice; women, children, and adolescents; and short-term residential and day treatment models. The papers in each of these sections describe, often in lengthy detail, the experimental design and outcomes. Because many of the studies were ongoing when this book was compiled, only preliminary results are cited. Of the 15 studies presented, some appear quite well designed and thought out, while others are not as comprehensive. Seven of the 15 studies were contributed by the Center for Therapeutic Community Research, which is funded by NIDA, and NIDA also funded most of the other studies.
