Abstract

Child Behavior-Analytic Therapy (CBAT) is based in behavior analysis and radical behaviorism to deal with children in clinical psychotherapy. Shaping is a process which is assumed to promote expected changes and transition probability is a strategy to study process in psychotherapy research. The objective of this study is to describe the process of directly shaping repertoires in two cases of Child Behavior-Analytic Therapy (CBAT) through a transitional probability procedure. Functional Analytic Psychotherapy Rating Scale (FAPRS) was used to code clients behaviors and Multidimensional System for Coding Behaviors in Therapist-Client Interaction (SiMCCIT) to code therapists ones, with The Observer Pro software. Measures of behavior duration and transitional probability were taken from two samples of 10 sessions each, of two CBAT treatments conducted by undergraduate therapists under clinical practicum supervision with two children, a 10-year-old girl and a seven-year-old boy, both with learning difficulties. The first treatment was successful and lasted 18 sessions. The second one continued but only observations of the first year of treatment were carried out. Problem behavior (CRB1) decreased, Improvement behavior (CRB2) and Descriptions of Controlling Variables (CRB3) increased in the first case. In the second case, CCR1 predominated through seven sessions, and CCR2 and CCR3 did not show stability. Transitional probabilities indicated regularities in therapists responding to the clients clinically relevant behavior, particularly Approvals after CCR2. These results suggests that shaping repertories by differential therapists responding is a mechanism of change in CBAT and supports the advantages of determining transitional probabilities from coded behaviors to explore the particular events that occur in therapeutic interaction (AU)
