The field of behavior therapy has expanded to the point where it is impossible to be knowledgeable about all the assessment strategies practiced by clinicians on a daily basis. This resource incorporates descriptions of both major and minor behavioral assessment techniques written by their leading proponents and practitioners in the field. A new preface by the editors contributes to the book’s currency. Originally published by Pergamon Press in 1988. From the Preface: 'When we first edited the Dictionary of Behavioral Assessment Techniques, it became clear to us that the field of behavior therapy had expanded to such a considerable extent that it was impossible (even for the so-called experts) to be knowledgeable about all of the assessment strategies carried out by our colleagues on a day-to-day basis. We therefore concluded that a dictionary, incorporating clear descriptions of major and minor techniques, would be of value to the field.'
