The Client as a lommon factor: Clients as Self-tiealers Until lions have their historians, all tales of hunting will glorify the hunter.-African proverb. ur thesis in this chapter is that the client's capacity for selfhealing is the most potent common factor in psychotherapy. It is the "engine" that makes therapy work (Bohart 6 Tallman, 1999; Bohart 6 Tallman, 1996). Therapy facilitates naturally occurring healing aspects of clients' lives. Therapists function as support systems and resource providers. This view contrasts with most of the literature on psychotherapy. There, the therapist is the "hero" who, with potent techniques and procedures, intervenes in clients' lives and fixes their malfunctioning machinery, be they faulty cognitions, weak and ineffectual egos, primitive defensive structures, conditioned maladaptive behaviors, defective social skills, or poorly working internal selforganizations.In this chapter we argue that the most parsimonious explanation for the dodo bird verdict is that it is the client, not the therapist or technique, that makes therapy work. After making the empirical case for client centrality in therapeutic change, we then present our model of client generativity and self-healing and discuss its implications for therapy.
