In the therapeutic community (TC) perspective, changing the whole person unfolds in the continual interaction between the individual and the community. This chapter provides the multidimensional picture of social and psychological change in terms of behaviors, cognitions, and emotions. Four major dimensions reflect the community’s objective view of individual change. The dimensions of community member and socialization refer to the social development of the individual specifically as a member of the TC community and generally as a prosocial participant in the larger society. The developmental and psychological dimensions refer to the evolution of the individual as a unique person, in terms of personal growth, personality, and psychological function. Each illustrates typical indicators of individual change in terms of objective behaviors, cognitions, and emotions. Changing the “whole person”, however, includes how individuals perceive and experience the program, the treatment, and themselves in the process.

As components of the therapeutic community (TC) treatment model, the stages define the program’s plan for moving individuals toward the goals of social and psychological change. This chapter describes the process of change in the TC in terms of participation and levels of involvement. It focuses on participation and community as method through the program stages. The chapter outlines some relations between the social and psychological dimensions of individual change and the community expectations for participation. It also describes the process of multidimensional change through treatment in terms of levels of involvement in the community. Participation and involvement link community as method to the individual in the change process. The terms engagement, immersion, and emergence label the individual’s level of involvement in the community. Perceptions related to self and identity are incremental through the levels of involvement.
