This article reviews controlled trials of hypnotic treatment for chronic pain in terms of: (1) analyses comparing the effects of hypnotic treatment to six types of control conditions; (2) component analyses; and (3) predictor analyses. The findings indicate that hypnotic analgesia produces significantly greater decreases in pain relative to no-treatment and to some non-hypnotic interventions such as medication management, physical therapy, and education/advice. However, the effects of self-hypnosis training on chronic pain tend to be similar, on average, to progressive muscle relaxation and autogenic training, both of which often include hypnotic-like suggestions. None of the published studies have compared hypnosis to an equally credible placebo or minimally effective pain treatment, therefore conclusions cannot yet be made about whether hypnotic analgesia treatment is specifically effective over and above its effects on patient expectancy. Component analyses indicate that labeling versus not labeling hypnosis treatment as hypnosis, or including versus not including hand-warming suggestions, have relatively little short-term impact on outcome, although the hypnosis label may have a long-term benefit. Predictor analyses suggest that global hypnotic responsivity and ability to experience vivid images are associated with treatment outcome in hypnosis, progressive relaxation, and autogenic training treatments. The paper concludes with a discussion of the implications of the findings for future hypnosis research and for the clinical applications of hypnotic analgesia.

Pregnancy presents many problems without working through additional problems in coping with an ostomy. Yet many women with an ostomy do get pregnant and do deliver healthy babies. Evidence-based nursing is of the utmost importance, as there is little published information on this topic. Because of the scarcity of pregnant subjects within the ostomy category, most studies, by necessity, select a purposive subject base. Therefore, other information sources regarding nursing management of the pregnant woman with an ostomy take on considerably more importance.This article explores other forms of evidence that can be used in managing the care of pregnant ostomy patients and specifically how nurses can integrate various sources of information in designing an evidence-based nursing care plan. Nonpharmacologic forms of relaxation therapy, easily used by nurses, such as mindfulness-based stress reduction, guided imagery, and hypnosis, are also identified as some ways nurses can relieve anxiety and experiential stress associated with pregnancy in women who have an ostomy.

Somatic symptoms have been conceptualized in many different ways in literature. Current classifications mainly focus on the numbers of symptoms, with relative neglect of the underlying psychopathology. Researchers have emphasized the importance of a number of experiential, perceptual and cognitive-behavioural aspects of somatization. This review focuses on existing literature on the role of somatosensory amplification, attribution styles, and illness behaviour in somatization. Evidence suggests that somatosensory amplification is neither sensitive nor specific to somatizing states, and that other factors like anxiety, depression, neuroticism, alexithymia may also have an influence. Attribution research supports the existence of multiple causal attributions, which are related to the numbers of somatic symptoms. While somatizing patients have more organic attributions, depressed patients have more psychological attributions. A global somatic attribution style is associated with the number of obscure somatic symptoms, while a psychological attribution style is associated with both--psychological and somatic-- symptoms of depression and anxiety. There are conflicting findings with respect to the role of normalizing attributions in reducing physician recognition of anxiety and depression. Specific symptom attributions appear to explain physician recognition of psychological distress, but global attribution styles do not appear to explain any further variance in physician recognition beyond that explained by specific causal attributions. Illness behaviour has been studied in two distinct ways in literature. Research focusing on attendance rates as a form of illness behaviour suggests that somatization is associated with high levels of health care utilization. There is also some evidence that health care utilization, amplification and attributions styles may be interrelated among somatizing patients. More structured ways to assess illness behaviour have found high levels of abnormal illness behaviour in this population. Overall, research appears to suggest a complex (and as yet unclear) relationship between somatic symptoms and underlying cognitions/illness behaviours. While it is clear that somatization is closely related to a number of perceptual and cognitive-behavioural factors, the precise nature of these relationships are yet to be elucidated.

In western populations irritable bowel syndrome (IBS) affects between 10% and 30% of the population and has a significant effect on quality of life. It generates a substantial workload in both primary and secondary care and has significant cost implications. Gut-directed hypnotherapy has been demonstrated to alleviate symptoms and improve quality of life but has not been assessed outside of secondary and tertiary referral centres. AIM: To assess the effectiveness of gut-directed hypnotherapy as a complementary therapy in the management of IBS. DESIGN OF STUDY: Randomised controlled trial. SETTING: Primary care patients aged 18-65 years inclusive, with a diagnosis of IBS of greater than 6 weeks' duration and having failed conventional management, located in South Staffordshire and North Birmingham, UK. METHOD: Intervention patients received five sessions of hypnotherapy in addition to their usual management. Control patients received usual management alone. Data regarding symptoms and quality of life were collected at baseline and again 3, 6, and 12 months post-randomisation. RESULTS: Both groups demonstrated a significant improvement in all symptom dimensions and quality of life over 12 months. At 3 months the intervention group had significantly greater improvements in pain, diarrhoea and overall symptom scores (P<0.05). No significant differences between groups in quality of life were identified. No differences were maintained over time. Intervention patients, however, were significantly less likely to require medication, and the majority described an improvement in their condition. CONCLUSIONS: Gut-directed hypnotherapy benefits patients via symptom reduction and reduced medication usage, although the lack of significant difference between groups beyond 3 months prohibits its general introduction without additional evidence. A large trial incorporating robust economic analysis is, therefore, urgently recommended.
