Reaffirming the importance of analysis in applied behavior analysis: A review of Functional Analysis of Problem Behavior: From Effective Assessment to Effective Support, edited by A. C. Repp and R. H. Horner

In recent years, much has been written about the topics of functional asses sment and functional analysis in applied settings. In their book, Functiona l Analysis of Problem Behavior: From Effective Assessment to Effective Supp ort. Repp and Horner (1999) have compiled a series of essays from experts o n the topic. In this article, we review their work and comment on each chap ter's contribution to the relevant literature. We conclude that the book me ets its primary goals of expanding our view of Functional analysis as well as providing those new to the field with a stronger understanding of the to pic. We do, however, note some concerns with inconsistent use of functional analysis terminology and a lack of practical guidance regarding ics implem entation in applied settings, but we believe these limitations are inherent in the empirical literature and are nor unique to this book. Thus, we stro ngly endorse this book as "must reading" for behaviorally oriented research ers, students, and practitioners.
