Toward Resolution of Conceptual Issues in the Assessment of Belief Systems in Rational-Emotive Therapy
This article reviews the major developments within the theory of rational-emotive therapy (RET) over the past decade. The absence of adequate validation of the theory’s assumptions is argued to be a function of poorly operationalized irrational belief instruments and the use of inappropriate samples. The present study undertakes the development of a research instrument to assess irrational belief processes. The instrument, the Attitudes and Beliefs Inventory (ABI), was administered to groups of emotionally disturbed and non-disturbed individuals (i.e., anxiety neurotics, agoraphobics, depressive neurotics, and normal controls). Findings from analyses of the simple main effects offer strong and consistent support to the rational-emotive model.
