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.
