The efficacy of rational emotive therapy in adults: clinical fact or psychometric artifact?

The efficacy of Rational-Emotive Therapy (RET) in reducing maladjustment, while insistently touted by its advocates, has not been unambiguously demonstrated in outcome research. Previous reviews have generally been quite partisan and subjective, and have not reflected available research. The object of the present review was to determine the extent to which RET significantly improved adjustment of adult subjects on different outcome measures in comparison with wait-list, placebo, and other treatment conditions. In 75 outcome reports, RET was effective in only about 25% of comparisons. Its main effect was to reduce scores of self-reported irrationality and dysphoria. Little change was noted in behavioral measures. The few comparisons favoring RET could be attributed to psychometric artifacts rather than to the reduction of irrational beliefs.
