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. The job of a functional analytic psychotherapist is to identify the interpersonal problems with the patient as they happen in session or out of session. Initial goals of functional analytic psychotherapy are set by the therapist and include behaviors that fit the client's needs for improvement. 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 § The five rules 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. Functional analytic psychotherapy differs from the traditional psychotherapy due to the fact that the therapist directly addresses the patterns of behavior as they occur in-session.
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. The in-session behaviors of the patient or client are considered to be examples of their patterns of poor interpersonal communication and to adjust their neurotic defenses. To do this, the therapist must act on the client's behavior as it happens in real time and give feedback on how the client's behavior is affecting their relationship during therapy. The therapist also helps the client with histrionic personality disorder by denoting behaviors that happen outside of treatment; these behaviors are termed "Outside Problems" and "Outside Improvements". This allows the therapist to assist in problems and improvements outside of session and to verbally support the client and condition optimal patterns of behavior". This then can reflect on how they are advancing in-session and outside of session by generalizing their behaviors over time for changes or improvement". 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. The five rules are not rules in the traditional sense of the word, but instead a set of guidelines for the FAP therapist.
Watch for CRBs – Therapists focus their attention on the occurrence of CRBs that are in-session problems (CRB1s) and improvements (CRB2s). Evoke CRBs– Therapists set a context which evoke the client's CRBs. Reinforce CRB2s naturally – Therapists reinforce the occurrence of CRB2s (in-session improvements), increasing the probability that these behaviors will occur more frequently. 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. Provide functional interpretations and generalize – Therapists work with the client to generalize in-session behavioral improvements to the client's out-of-session relationships. This can include, but is not limited to, providing homework assignments.
The ACL model Researchers at the Center for the Science of Social Connection at the University of Washington are developing a model of social connection that they believe is relevant to FAP. This model – called the ACL model – delineates behaviors relevant to social connection based on decades of scientific research.
Awareness (A) behaviors include paying attention to your own and the other's needs and values within an interpersonal relationship. Courage (C) behaviors include experiencing emotion in the presence of another person, asking for what you need, and sharing deep, vulnerable experiences with another person in the service of improving the relationship. Love (L) behaviors involve responding to another's courage behaviors with attunement to what that person needs in the moment. These include providing safety and acceptance in response to a client's vulnerability. FAP has the potential to target awareness, courage, and love behaviors as they occur in session as described by the five rules above. More research is needed to confirm the utility of the ACL model.
Coding client and therapist behaviors In these sessions there is a certain set of dialogue, or a script, that can be forced by the therapist for the client to give insight on their behaviors and reasoning. Here is an example; the conversation is hypothetical. T = therapist C = Client. This coded dialogue can be transcribed as:
