Hypnosis for irritable bowel syndrome: the empirical evidence of therapeutic effects.
ABSTRACT Irritable bowel syndrome (IBS) is a complex and prevalent functional gastrointestinal disorder that is treated with limited effectiveness by standard medical care. Hypnosis treatment is, along with cognitive-behavioral therapy, the psychological therapy best researched as an intervention for IBS. Eleven studies, including 5 controlled studies, have assessed the therapeutic effects of hypnosis for IBS. Although this literature has significant limitations, such as small sample sizes and lack of parallel comparisons with other treatments, this body of research consistently shows hypnosis to have a substantial therapeutic impact on IBS, even for patients unresponsive to standard medical interventions. The median response rate to hypnosis treatment is 87%, bowel symptoms can generally be expected to improve by about half, psychological symptoms and life functioning improve after treatment, and therapeutic gains are well maintained for most patients for years after the end of treatment.

ABSTRACT: - Objectives Psychological interventions can alleviate the symptoms of irritable bowel syndrome (IBS) and psychological distress commonly reported among IBS sufferers. However, the theoretical underpinnings and intervention techniques used by such interventions vary considerably. This study aimed to identify which theoretical approaches and techniques lead to greater improvements in IBS symptoms and psychological well-being within psychological interventions for IBS. Methods Outcome data were extracted from 48 randomized controlled trials testing psychological treatments for IBS. Theoretical intervention targets and intervention techniques of each study were identified. Cumulative effect sizes were calculated for pain, bowel dysfunction, composite symptom scores, psychological distress, and health-related quality of life. Comparative analyses contrasted the effect sizes of studies which included each intervention technique to those which did not. Results Cumulatively, interventions significantly improved all outcomes, with effect sizes (Hedges' g) ranging from 0.32 to 0.64. Interventions which stated a theoretical intervention target, prompted self-monitoring of symptoms and cognitions, provided tailored feedback linking symptoms and cognitions, utilized problem solving or assertiveness training and provided general support had greater effects upon symptom and well-being outcomes than interventions which did not (all P < .05). Across all studies, improvements in psychological distress were associated with improvements in composite symptom scores (P < .01). Conclusions This study identifies a set of techniques associated with improvements in IBS symptoms and psychological well-being in existing interventions, and provides initial evidence for the link between improvements in psychological distress and IBS composite symptom scores. These findings can aid the development and refinement of psychological treatments for IBS.Journal of Psychosomatic Research 12/2014; 78(3). DOI:10.1016/j.jpsychores.2014.12.009 · 2.84 Impact Factor

ABSTRACT: The authors tested tailored hypnotic inductions for age regression with an affect bridge to access meaning-laden events. They used emotional intensity, spontaneity, elaboration, and transitional-object measures to assess the genuineness of the topographic shift to primary process characteristic of hypnotic age regression. An affect bridge was used to access stressful events within the age range of 3 to 6 years. The Stanford Hypnotic Susceptibility Scale, Form C was administered to determine high hypnotizables-reals, (n = 8, scores 9-12) and low hypnotizables-simulators, (n = 8, scores 3 or less). The groups behaved differently on frequency of transitional objects, spontaneity, and intensity but not on elaboration. The hypnotizable-reals but not the simulators produced a plethora of primary-process childlike affective responses that could not be produced by the role-playing simulators.International Journal of Clinical and Experimental Hypnosis 10/2009; 57(4):402-18.

ABSTRACT: Six papers of special interest to the hypnosis community have recently appeared in the general scientific literatures. Three of these papers were published as part of the 2006 Cochrane Collaboration on the utility of medical interventions. These reviews analyze the research literature on the efficacy of hypnosis for treatment of needle-related pain in children, pain management during childbirth, and conversion disorder. Hypnosis is the most promising psychological intervention studied for needle-related procedural pain and distress in children and adolescents; it is effective as an adjunctive analgesic during childbirth; and it is of uncertain usefulness in treatment of conversion disorder. A second cluster of three studies unambiguously demonstrates the central role of hypnotizability as a predictor of responsiveness in laboratory, analogue treatment, and medical practice settings. One of these articles may well be the most important hypnosis paper in many years.International Journal of Clinical and Experimental Hypnosis 08/2007; 55(3):372-9. DOI:10.1080/00207140701339793
