Energy psychology utilizes imaginal and narrative-generated exposure, paired with interventions that reduce hyperarousal through acupressure and related techniques. According to practitioners, this leads to treatment outcomes that are more rapid, powerful, and precise than the strategies used in other exposure-based treatments such as relaxation or diaphragmatic breathing. The method has been exceedingly controversial. It relies on unfamiliar procedures adapted from non-Western cultures, posits unverified mechanisms of action, and early claims of unusual speed and therapeutic power ran far ahead of initial empirical support. This paper reviews a hierarchy of evidence regarding the efficacy of energy psychology, from anecdotal reports to randomized clinical trials. Although the evidence is still preliminary, energy psychology has reached the minimum threshold for being designated as an evidence-based treatment, with one form having met the APA Division 12 criteria as a "probably efficacious treatment" for specific phobias; another for maintaining weight loss. The limited scientific evidence, combined with extensive clinical reports, suggests that energy psychology holds promise as a rapid and potent treatment for a range of psychological conditions.
