Relationship between cognitive appraisals of symptoms and negative mood for subtypes of irritable bowel syndrome
<p>Abstract</p> <p>Background</p> <p>The onset and course of irritable bowel syndrome (IBS) are strongly influenced by psychological factors, and treatment often includes cognitive-behavioral therapy. We conducted a study of the relationships between cognitive appraisal of IBS symptoms and negative mood for the subtypes of IBS.</p> <p>Method</p> <p>The participants were 1087 college students who completed a set of questionnaires that included the Rome II Modular Questionnaire, Self-reported IBS Questionnaire, Cognitive Appraisal Rating Scale, and the Hospital Anxiety and Depression Scale.</p> <p>Results</p> <p>The participants included 206 individuals with IBS; 61 had diarrhea-predominant IBS (IBSD) and 45 had constipation-predominant IBS (IBSC). The overall IBS group scored higher on anxiety and depression than the control group. The IBSD and IBSC groups each had significantly higher scores for anxiety but did not significantly differ from the control group in scores for depression. There were no significant differences between the IBSD and IBSC groups in their cognitive appraisal of IBS symptoms. For the IBSD group, anxiety was significantly, positively correlated with commitment, effect, and threat, and depression was significantly, negatively correlated with controllability. In contrast, there were no significant correlations between mood and cognitive appraisal for the IBSC group. Multiple regression analyses with abdominal symptoms as dependent variables and cognitive appraisals as independent variables showed that for the IBSD group, abdominal pain was significantly, positively correlated with commitment, and abdominal discomfort was significantly, positively correlated with appraisal of effect and threat. For the IBSC group, abdominal pain and hard stool were significantly, positively correlated with commitment, and abdominal discomfort was significantly, positively correlated with appraisal of effect and threat.</p> <p>Conclusion</p> <p>IBS patients as a general group report high levels of anxiety and depression. However, IBSD and IBSC were both associated only with high anxiety, but not depression, when compared to the non-IBS control group. For the IBSD group, anxiety was associated with cognitive appraisals, but this association was not found for the IBSC group. These groups did not differ in their associated cognitive appraisals, and are similar in terms of the positive relationship between abdominal pain and discomfort and the cognitive appraisals of coping.</p
A randomised controlled trial on hypnotherapy for irritable bowel syndrome: design and methodological challenges (the IMAGINE study)
<p>Abstract</p> <p>Background</p> <p>Irritable Bowel Syndrome (IBS) is a common gastro-intestinal disorder in primary and secondary care, characterised by abdominal pain, discomfort, altered bowel habits and/or symptoms of bloating and distension. In general the efficacy of drug therapies is poor. Hypnotherapy as well as Cognitive Behaviour Therapy and short Psychodynamic Therapy appear to be useful options for patients with refractory IBS in secondary care and are cost-effective, but the evidence is still limited. The IMAGINE-study is therefore designed to assess the overall benefit of hypnotherapy in IBS as well as comparing the efficacy of individual versus group hypnotherapy in treating this condition.</p> <p>Methods/Design</p> <p>The design is a randomised placebo-controlled trial. The study group consists of 354 primary care and secondary care patients (aged 18-65) with IBS (Rome-III criteria). Patients will be randomly allocated to either 6 sessions of individual hypnotherapy, 6 sessions of group hypnotherapy or 6 sessions of educational supportive therapy in a group (placebo), with a follow up of 9 months post treatment for all patients. Ten hospitals and four primary care psychological practices in different parts of The Netherlands will collaborate in this study. The primary efficacy parameter is the responder rate for adequate relief of IBS symptoms. Secondary efficacy parameters are changes in the IBS symptom severity, quality of life, cognitions, psychological complaints, self-efficacy as well as direct and indirect costs of the condition. Hypnotherapy is expected to be more effective than the control therapy, and group hypnotherapy is expected not to be inferior to individual hypnotherapy.</p> <p>Discussion</p> <p>If hypnotherapy is effective and if there is no difference in efficacy between individual and group hypnotherapy, this group form of treatment could be offered to more IBS patients, at lower costs.</p> <p>Trial registration number</p> <p>ISRCTN: <a href="http://www.controlled-trials.com/ISRCTN22888906">ISRCTN22888906</a></p
Participants’ perspectives on mindfulnessbased cognitive therapy for inflammatory bowel disease: a qualitative study nested within a pilot randomised controlled trial
Background: Mindfulness-based interventions have shown to improve depression and anxiety symptoms as well as
quality of life in patients with inflammatory bowel disease (IBD). However, little is known about the experiences of
this group of patients participating in mindfulness interventions. This paper sets out to explore the perspectives of
patients with IBD recruited to a pilot randomised controlled trial (RCT) of mindfulness-based cognitive therapy
(MBCT) about the intervention.
Methods: In a qualitative study nested within a parallel two-arm pilot RCT of mindfulness-based cognitive therapy
for patients with IBD, two focus group interviews (using the same schedule) and a free text postal survey were
conducted. Data from both were analysed using thematic analysis. Data and investigator triangulation was
performed to enhance confidence in the ensuing findings.
Forty-four patients with IBD were recruited to the pilot RCT from gastroenterology outpatient clinics from two
Scottish NHS boards. Eighteen of these patients (ten from mindfulness intervention and eight from control group)
also completed a postal survey and participated in two focus groups after completing post intervention
assessments.
Results: The major themes that emerged from the data were the following: perceived benefits of MBCT for IBD,
barriers to attending MBCT and expectations about MBCT. Participants identified MBCT as a therapeutic, educational
and an inclusive process as key benefits of the intervention. Key barriers included time and travel constraints.
Conclusions: This qualitative study has demonstrated the acceptability of MBCT in a group of patients with IBD.
Participants saw MBCT as a therapeutic and educational initiative that transformed their relationship with the illness.
The inclusive process and shared experience of MBCT alleviated the sense of social isolation commonly associated
with IBD. However, time commitment and travel were recognised as a barrier to MBCT which could potentially
influence the degree of therapeutic gain from MBCT for some participants.

Review article: The history of hypnotherapy and its role in the irritable bowel syndrome
Hypnosis is a technique by which an individual can gain a degree of control over physiological as well as psychological function. This paper reviews the history of the phenomenon as well as the accumulating evidence that it is effective in relieving the symptoms of irritable bowel syndrome and improving the quality of life of sufferers. The physiolo-gical effects of hypnosis are also discussed coupled with an outline of how a hypnotherapy service might be provided. HISTORICAL BACKGROUN
Establishing how psychological therapies work: the importance of mediation analysis
This editorial reviews the literature regarding psychological studies that are designed to address the question of not just whether, psychological interventions effect change, but how. The practicalities and implications of assessing mechanisms of treatments are considered with examples from the fields of Cognitive Behavioural Therapy (CBT) and Mindfulness. The potential for elucidating theoretical mechanisms, developing new theoretical models and modifying treatment approaches are described. In addition an overview of different types of statistical methods available to researchers for assessing mediation is given. Structural Equation Modelling (SEM) is a recommended approach. The review concludes with a summary of optimum study conditions adopted by researchers for establishing mediating effects

Correlation between symptoms of the irritable bowel syndrome and the response to the food extract skin prick test
The relationship between the irritable bowel syndrome (IBS) and food intolerance is not clear. We studied the cutaneous response to food antigens in 43 volunteers who were students and employees of the Faculty of Medicine of Universidade Federal Fluminense. Subjects were divided into 3 groups after evaluation for Roma II criteria for functional disease of the gastrointestinal tract: group I, 14 volunteers with IBS; group II, 15 volunteers with functional dyspepsia; group III, 14 volunteers without habitual gastrointestinal symptoms. The subjects were submitted to the skin prick test with 9 food antigen extracts, for a total of 387 skin tests (9 per volunteer). Of the 126 tests applied to group I, 24 (19.4%) were positive (a 3-mm wider papule than the negative control) and of the 135 tests applied to group II, 3 (2.3%) were positive. Of the 126 tests applied to group III, 6 (4%) were positive. The number of positive responses obtained in group I (IBS) differed significantly from the other 2 groups (P < 0.01). None of the volunteers with IBS reported intolerance to any isolated food. The higher reactivity to food antigens in group I compared to groups II and III suggests that intestinal permeability may be increased in patients with IBS
