 The Efficacy of Rational Emotive Therapy: A Quantitative Review of the Outcome Research.

Results

Table 1 presents several demographic characteristics of the studies examined in the present quantitative review. Year of publication ranged from 1970 to 1988, with a median of 1978.5. Publication year was not related to effect size. The median training level for the therapists was 5.000 (PhD candidate or psychiatric resident). Therapist training was significantly related to effect size. The number of subjects per comparison was also significantly related to effect size, smaller number of participants in each comparison group was related to larger effect sizes. The mean age of the subjects, and the percentage of male subjects were not related to effect size

Significant differences were found between the different diagnostic groups (F (4,231) = 6.443, p < .001). as shown in Table 3. Comparisons using participants with emotional-somatic problems tended to have significantly higher effect sizes than those comparisons in the other diagnostic categories. Comparisons in the neurotic category had significantly higher effect sizes than those comparisons using normal subjects. No other difference between comparisons was significant.
