Area of Science:

• Psychology
• Clinical Psychology
• Psychotherapy Research

Background:

• Rational Emotive and Cognitive-Behavioral Therapy (REBT) is a well-established psychotherapeutic approach.
• Its effectiveness has been documented in research settings, but translation to clinical practice requires validation.

Purpose of the Study:

• To evaluate the effectiveness of REBT in a real-world clinical setting.
• To assess patient functioning improvements following REBT interventions.

Main Methods:

• A cohort of 349 patients from the Albert Ellis Institute undergoing psychotherapy between 2007 and 2016 were included.
• Intent-to-treat analyses were performed, measuring outcomes at three and twenty sessions using the Outcome Questionnaire-45.

Main Results:

• Patients demonstrated statistically significant improvements in functioning.
• A medium effect size was observed for early response after three sessions.
• Sustained improvements were noted by the end of twenty sessions.

Conclusions:

• REBT is effectively transferable from research environments to clinical practice.
• The findings support the utility of REBT for enhancing patient functioning in routine care.
