Abstract
This article examines 32 important clinical and personality hypotheses of rational-emotive therapy (RET) and other modes of cognitive-behavior therapy and lists a large number of research studies that provide empirical confirmation of these hypotheses. It concludes that (1) a vast amount of research data exists, most of which tends to confirm the major clinical and personality hypotheses of RET; (2) this data keeps increasing by leaps and bounds; (3) RET hypotheses nicely lend themselves to experimental investigation and therefore encourage a considerable amount of research; (4) researchers have not yet tested some of the major RET formulations and could do so with profit to the field of psychotherapy and personality theory.
