Functional analytic psychotherapy
Functional analytic psychotherapy (FAP) is a psychotherapeutic approach based on clinical behavior analysis (CBA) that focuses on the therapeutic relationship as a means to maximize client change. Specifically, FAP suggests that in-session contingent responding to client target behaviors leads to significant therapeutic improvements. FAP was first conceptualized in the 1980s by psychologists Robert Kohlenberg and Mavis Tsai who, after noticing a clinically significant association between client outcomes and the quality of the therapeutic relationship, set out to develop a theoretical and psychodynamic model of behavioral psychotherapy based on these concepts. Behavioral principles (e.g., reinforcement, generalization) form the basis of FAP. (See below.) FAP is an idiographic (as opposed to nomothetic) approach to psychotherapy. This means that FAP therapists focus on the function of a client's behavior instead of the form. The aim is to change a broad class of behaviors that might look different on the surface but all serve the same function. It is idiographic in that the client and therapist work together to form a unique clinical formulation of the client's therapeutic goals, rather than one therapeutic target for every client who enters therapy. Basics FAP posits that client behaviors that occur in their out-of-session interpersonal relationships (i.e. in the "real world") will, if clients are given a therapeutic relationship of sufficiently high quality, occur in the therapy session as well. Based on these in-session behaviors, FAP therapists, in collaboration with their client, develop a case formulation that includes classes of behaviors (based on their function not their form) that the client wishes to increase and decrease. In-session occurrence of a client's problematic behavior is called clinically relevant behavior 1 (CRB1). In-session occurrence of improvements is called clinically relevant behavior 2 (CRB2). The goal of FAP therapy is to decrease the frequency of CRB1s and increase the frequency of CRB2s. The FAP therapist evokes (i.e. sets the context for) CRB1s and in response gradually shapes CRB2s. The five rules "The five rules" operationalize the FAP therapist's behavior with respect to this goal. It is important to note that the five rules are not rules in the traditional sense of the word, but instead a set of guidelines for the FAP therapist. Rule 1: Watch for CRBs – Therapists focus their attention on the occurrence of CRBs that are in-session problems (CRB1s) and improvements (CRB2s). Rule 2: Evoke CRBs – Therapists set a context which evoke the client's CRBs. Rule 3: Reinforce CRB2s naturally – Therapists reinforce the occurrence of CRB2s (in-session improvements), increasing the probability that these behaviors will occur more frequently. Rule 4: Observe therapist impact in relation to client CRBs – Therapists assess the degree to which they actually reinforced behavioral improvements by noting the client's behavior subsequent behavior after Rule 3. This is similar to the behavior analytic concept of performing a functional analysis. Rule 5: Provide functional interpretations and generalize – Therapists work with the client to generalize in-session behavioral improvements to the client's out-of-session relationships.
