This study evaluated the effects of a Cognitive Experiential Therapy (CET)—in the pastreferred to as Rational Stage Directed Hypnotherapy (RSDH)—Cognitive Restructuring (CR), Hypnosis Only (HO), and a no-treatment control condition on the duodenal ulcer syndrome. CET or RSDH is a systematic, stage-directed therapy that employs hypnosis and the cognitive restructuring of self-defeating cognitive, emotional, physiological, and behavioral tendencies. Seven criterion variables were assessed using two standardized instruments and ques-tionnaire data. The standardized instruments included the Millon Behavioral Health Inventory (MBHI) and the Common Beliefs Survey ID (CBS III).
Twenty-five volunteer duodenal ulcer patients served as subjects for the study. The research design, a 4 X 3 factorial design with repeated measures, consisted of four treatment levels (Control, CR, HO, and RSDH) and three time periods (pretest, posttest, and follow-up) over which the subjects were observed. MANOVA on residualized change scores revealed a significant treatment effect. Univariate effects were observed on the MBHI personality coping styles, CBS III evaluation and locus of control scales, and gastrointestinal disturbance. GET appeared to have an ameliorative effect on psychological factors associated with duodenal ulcer.
