Internet-delivered exposure-based treatment vs. stress management for irritable bowel syndrome: a randomized trial

Collateral outcomes in e-mental health: a systematic review of the evidence for added benefits of computerized cognitive behavior therapy interventions for mental health

BACKGROUND

E-mental health is a growing research field and an increasing number of computerized cognitive behavior therapy (cCBT) interventions are available for numerous mental health issues. Such interventions are often claimed to have added benefits, or collateral outcomes, when compared with traditional delivery platforms. Our aim was to systematically review the evidence of the cost-effectiveness, geographic flexibility, time flexibility, waiting time for treatment, stigma, therapist time, effects on help-seeking and treatment satisfaction of cCBT interventions for mental health.

METHOD

The electronic databases Medline and Web of Science were searched for peer-reviewed controlled trials investigating collateral outcomes in computerized and internet-based CBT.

RESULTS

The literature search identified 101 published papers (95 studies), which were included in this review. The results suggest that cCBT interventions are cost-effective and often cheaper than usual care. Limited evidence was found with regard to geographic flexibility, time flexibility, waiting time for treatment, stigma and the effects on help-seeking. Personal support in cCBT was found to take many forms, was not limited only to therapists, and seemed to increase treatment adherence and reduce attrition. Treatment satisfaction with cCBT was found to be high, but more research on attrition due to dissatisfaction is required.

CONCLUSIONS

Although the results of this systematic review on the collateral outcomes provide support for the potential of cCBT, these outcomes need to be better assessed within individual e-mental health studies.

Internet-delivered exposure-based cognitive-behavioural therapy and behavioural stress management for severe health anxiety: randomised controlled trial

BACKGROUND

Exposure-based cognitive-behavioural therapy (CBT) delivered via the internet has been shown to be effective for severe health anxiety (hypochondriasis) but has not been compared with an active, effective and credible psychological treatment, such as behavioural stress management (BSM).

AIMS

To investigate two internet-delivered treatments - exposure-based CBT v. BSM - for severe health anxiety in a randomised controlled trial (trial registration: NCT01673035).

METHOD

Participants (n = 158) with a principal diagnosis of severe health anxiety were allocated to 12 weeks of exposure-based CBT (n = 79) or BSM (n = 79) delivered via the internet. The Health Anxiety Inventory (HAI) was the primary outcome.

RESULTS

Internet-delivered exposure-based CBT led to a significantly greater improvement on the HAI compared with BSM. However, both treatment groups made large improvements on the HAI (pre-to-post-treatment Cohen's d: exposure-based CBT, 1.78; BSM, 1.22).

CONCLUSIONS

Exposure-based CBT delivered via the internet is an efficacious treatment for severe health anxiety.

Mindfulness-based therapies in the treatment of functional gastrointestinal disorders: a meta-analysis

Background. Functional gastrointestinal disorders are highly prevalent and standard treatments are often unsatisfactory. Mindfulness-based therapy has shown benefit in conditions including chronic pain, mood, and somatization disorders. Objectives. To assess the quality and effectiveness reported in existing literature, we conducted a meta-analysis of mindfulness-based therapy in functional gastrointestinal disorders. Methods. Pubmed, EBSCO, and Cochrane databases were searched from inception to May 2014. Study inclusion criteria included randomized, controlled studies of adults using mindfulness-based therapy in the treatment of functional gastrointestinal disorders. Study quality was evaluated using the Cochrane risk of bias. Effect sizes were calculated and pooled to achieve a summary effect for the intervention on symptom severity and quality of life. Results. Of 119 records, eight articles, describing seven studies, met inclusion criteria. In six studies, significant improvements were achieved or maintained at the end of intervention or follow-up time points. The studies had an unclear or high risk of bias. Pooled effects were statistically significant for IBS severity (0.59, 95% CI 0.33 to 0.86) and quality of life (0.56, 95% CI 0.47 to 0.79). Conclusion. Studies suggest that mindfulness based interventions may provide benefit in functional gastrointestinal disorders; however, substantial improvements in methodological quality and reporting are needed.

Treatment of abdominal pain in irritable bowel syndrome

Functional abdominal pain in the context of irritable bowel syndrome (IBS) is a challenging problem for primary care physicians, gastroenterologists and pain specialists. We review the evidence for the current and future non-pharmacological and pharmacological treatment options targeting the central nervous system and the gastrointestinal tract. Cognitive interventions such as cognitive behavioral therapy and hypnotherapy have demonstrated excellent results in IBS patients, but the limited availability and labor-intensive nature limit their routine use in daily practice. In patients who are refractory to first-line therapy, tricyclic antidepressants (TCA) and selective serotonin reuptake inhibitors are both effective to obtain symptomatic relief, but only TCAs have been shown to improve abdominal pain in meta-analyses. A diet low in fermentable carbohydrates and polyols (FODMAP) seems effective in subgroups of patients to reduce abdominal pain, bloating, and to improve the stool pattern. The evidence for fiber is limited and only isphagula may be somewhat beneficial. The efficacy of probiotics is difficult to interpret since several strains in different quantities have been used across studies. Antispasmodics, including peppermint oil, are still considered the first-line treatment for abdominal pain in IBS. Second-line therapies for diarrhea-predominant IBS include the non-absorbable antibiotic rifaximin and the 5HT3 antagonists alosetron and ramosetron, although the use of the former is restricted because of the rare risk of ischemic colitis. In laxative-resistant, constipation-predominant IBS, the chloride-secretion stimulating drugs lubiprostone and linaclotide, a guanylate cyclase C agonist that also has direct analgesic effects, reduce abdominal pain and improve the stool pattern.

Cognitive-behavioral therapy for irritable bowel syndrome: a meta-analysis

OBJECTIVE

To establish whether cognitive behavioral therapy (CBT) improves the bowel symptoms, quality of life (QOL) and psychological states of irritable bowel syndrome (IBS) patients.

METHODS

Randomized controlled trials (RCTs) of CBT for adult patients with IBS were searched by using PubMed, Scopus and Web of Science. The standardized mean difference (SMD) with 95% confidence intervals (CIs) of the evidence-based outcome measures of the IBS bowel symptoms, QOL and psychological states at post-treatment and follow-up was calculated. Prespecified subgroup analysis was performed.

RESULTS

Eighteen RCTs satisfied our inclusion criteria. In the subgroup analyses, CBT was more effective in reducing IBS bowel symptoms, QOL and psychological states than waiting list controls at the end of the intervention and short-term follow-up. When compared with controls of basic support and medical treatment, the effect sizes were found to favor CBT for the improvement of IBS bowel symptoms at post-treatment and short-term follow-up, but CBT was not superior to controls in improving QOL and psychological states. When comparing CBT with other psychological controls, the effect sizes were almost non-significant.

CONCLUSIONS

For IBS patients, CBT was superior to waiting list, basic support or medical treatment at the end of treatment but not superior to other psychological treatments. The meta-analysis might be limited by the heterogeneities and small sample sizes of the included studies.

Update on irritable bowel syndrome program of research

PURPOSE

This article provides an update and overview of a nursing research program focused on understanding the pathophysiology and management of irritable bowel syndrome (IBS).

METHODS

This review includes English language papers from the United States, Europe, and Asia (e.g., South Korea) from 1999 to 2013. We addressed IBS as a health problem, emerging etiologies, diagnostic and treatment approaches and the importance of a biopsychosocial model.

RESULTS

IBS is a chronic, functional gastrointestinal disorder characterized by recurrent episodes of abdominal pain and alterations in bowel habit (diarrhea, constipation, mixed). It is a condition for which adults, particularly women ages 20-45, seek health care services in both the United States and South Korea. Clinically, nurses play key roles in symptom prevention and management including designing and implementing approaches to enhance the patients' self-management strategies. Multiple mechanisms are believed to participate in the development and maintenance of IBS symptoms including autonomic nervous system dysregulation, intestinal inflammation, intestinal dysbiosis, dietary intolerances, alterations in emotion regulation, heightened visceral pain sensitivity, hypothalamic-pituitary-adrenal dysregulation, and dysmotility. Because IBS tends to occur in families, genetic factors may also contribute to the pathophysiology. Patients with IBS often report a number of co-morbid disorders and/or symptoms including poor sleep.

CONCLUSION

The key to planning effective management strategies is to understand the heterogeneity of this disorder. Interventions for IBS include non-pharmacological strategies such as cognitive behavior therapy, relaxation strategies, and exclusion diets.

A mixed methods feasibility study to evaluate the use of a low-intensity, nurse-delivered cognitive behavioural therapy for the treatment of irritable bowel syndrome

INTRODUCTION

Irritable bowel syndrome (IBS) is characterised by symptoms such as abdominal pain, constipation, diarrhoea and bloating. These symptoms impact on health-related quality of life, result in excess service utilisation and are a significant burden to healthcare systems. Certain mechanisms which underpin IBS can be explained by a biopsychosocial model which is amenable to psychological treatment using techniques such as cognitive behavioural therapy (CBT). While current evidence supports CBT interventions for this group of patients, access to these treatments within the UK healthcare system remains problematic.

METHODS AND ANALYSIS

A mixed methods feasibility randomised controlled trial will be used to assess the feasibility of a low-intensity, nurse-delivered guided self-help intervention within secondary care gastrointestinal clinics. A total of 60 participants will be allocated across four treatment conditions consisting of: high-intensity CBT delivered by a fully qualified cognitive behavioural therapist, low-intensity guided self-help delivered by a registered nurse, self-help only without therapist support and a treatment as usual control condition. Participants from each of the intervention arms of the study will be interviewed in order to identify potential barriers and facilitators to the implementation of CBT interventions within clinical practice settings. Quantitative data will be analysed using descriptive statistics only. Qualitative data will be analysed using a group thematic analysis.

ETHICS AND DISSEMINATION

This study will provide essential information regarding the feasibility of nurse-delivered CBT interventions within secondary care gastrointestinal clinics. The data gathered during this study would also provide useful information when planning a substantive trial and will assist funding bodies when considering investment in substantive trial funding. A favourable opinion for this research was granted by the Nottingham 2 Research Ethics Committee.

Utilization and efficacy of internet-based eHealth technology in gastroenterology: a systematic review

OBJECTIVE

While there have been several reviews exploring the outcomes of various eHealth studies, none have been gastroenterology-specific. This paper aims to evaluate the research conducted within gastroenterology which utilizes internet-based eHealth technology to promote physical and psychological well-being.

MATERIAL AND METHODS

A systematic literature review of internet-based eHealth interventions involving gastroenterological cohorts was conducted. Searched databases included: EbSCOhost Medline, CINAHL, and PsycINFO. Inclusion criteria were studies reporting on eHealth interventions (both to manage mental health problems and somatic symptoms) in gastroenterology, with no time restrictions. Exclusion criteria were non-experimental studies, or studies using only email as primary eHealth method, and studies in language other than English.

RESULTS

A total of 17 papers were identified; seven studies evaluated the efficacy of a psychologically oriented intervention (additional two provided follow-up analyses exploring the original published data) and eight studies evaluated disease management programs for patients with either irritable bowel syndrome, inflammatory bowel disease (IBD) or celiac disease. Overall, psychological eHealth interventions were associated with significant reductions in bowel symptoms and improvement in quality of life (QoL) that tended to continue up to 12 months follow up. The eHealth disease management was shown to generally improve QoL, adherence, knowledge about the disease, and reduce healthcare costs in IBD, although the studies were associated with various methodological problems, and thus, this observation should be confirmed in well-designed interventional studies.

CONCLUSIONS

Based on the evidence to date, eHealth internet-based technology is a promising tool that can be utilized to both promote and enhance gastrointestinal disease management and mental health.

Internet-based cognitive behavioral therapy for patients with chronic somatic conditions: a meta-analytic review

Background

Patients with chronic somatic conditions face unique challenges accessing mental health care outside of their homes due to symptoms and physical limitations. Internet-based cognitive behavioral therapy (ICBT) has shown to be effective for various psychological conditions. The increasing number of recent trials need to be systematically evaluated and quantitatively analyzed to determine whether ICBT is also effective for chronic somatic conditions and to gain insight into the types of problems that could be targeted.

Objective

Our goal was to describe and evaluate the effectiveness of guided ICBT interventions for chronic somatic conditions on general psychological outcomes, disease-related physical outcomes, and disease-related impact on daily life outcomes. The role of treatment length was also examined.

Methods

PubMed, PsycINFO, and Embase were searched from inception until February 2012, by combining search terms indicative of effect studies, Internet, and cognitive behavioral therapy. Studies were included if they fulfilled the following six criteria: (1) randomized controlled trial, (2) Internet-based interventions, (3) based on cognitive behavioral therapy, (4) therapist-guided, (5) adult (≥18 years old) patients with an existing chronic somatic condition, and (6) published in English. 23 randomized controlled trials of guided ICBT were selected by 2 independent raters after reviewing 4848 abstracts. Demographic, clinical, and methodological variables were extracted. Standardized mean differences were calculated between intervention and control conditions for each outcome and pooled using random effects models when appropriate.

Results

Guided ICBT was shown to improve all outcome categories with small effect sizes for generic psychological outcomes (effect size range 0.17-0.21) and occasionally larger effects for disease-specific physical outcomes (effect size range 0.07 to 1.19) and disease-related impact outcomes (effect size range 0.17-1.11). Interventions with a longer treatment duration (>6 weeks) led to more consistent effects on depression.

Conclusions

Guided ICBT appears to be a promising and effective treatment for chronic somatic conditions to improve psychological and physical functioning and disease-related impact. The most consistent improvements were found for disease-specific outcomes, which supports the possible relevance of tailoring interventions to specific patient groups. Explorative analyses revealed that longer treatment length holds the promise of larger treatment effects for the specific outcome of depression. While the current meta-analysis focused on several chronic somatic conditions, future meta-analyses for separate chronic somatic conditions can further consolidate these results, also in terms of cost-effectiveness.

[The therapeutic alliance in internet-based therapy procedures: an overview]

There has been an increased use of modern information and communication technology in healthcare services in recent years; however, little is yet known about the nature of the therapeutic alliance in internet-based interventions. This review aims to give a systematic overview of controlled evaluation studies with a focus on the nature and impact of the therapeutic alliance in internet-based interventions available to date. The results of internet-based randomized controlled trials indicate that a positive therapeutic alliance can be established regardless of the medium of communication. The therapeutic alliance was rated equally satisfying as in conventional face-to-face therapy.

Complementary and alternative medicines in irritable bowel syndrome: an integrative view

Irritable bowel syndrome (IBS) is a common gastrointestinal disorder with a high incidence in the general population. The diagnosis of IBS is mainly based on exclusion of other intestinal conditions through the absence of inflammatory markers and specific antigens. The current pharmacological treatment approaches available focus on reducing symptom severity while often limiting quality of life because of significant side effects. This has led to an effectiveness gap for IBS patients that seek further relief to increase their quality of life. Complementary and alternative medicines (CAM) have been associated with a higher degree of symptom management and quality of life in IBS patients. Over the past decade, a number of important clinical trials have shown that specific herbal therapies (peppermint oil and Iberogast(®)), hypnotherapy, cognitive behavior therapy, acupuncture, and yoga present with improved treatment outcomes in IBS patients. We propose an integrative approach to treating the diverse symptoms of IBS by combining the benefits of and need for pharmacotherapy with known CAM therapies to provide IBS patients with the best treatment outcome achievable. Initial steps in this direction are already being considered with an increasing number of practitioners recommending CAM therapies to their patients if pharmacotherapy alone does not alleviate symptoms sufficiently.

Guided and unguided CBT for social anxiety disorder and/or panic disorder via the Internet and a smartphone application: study protocol for a randomised controlled trial

Background

Smartphone technology presents a novel and promising opportunity to extend the reach of psychotherapeutic interventions by moving selected parts of the therapy into the real-life situations causing distress. This randomised controlled trial will investigate the effects of a transdiagnostic, Internet-administered cognitive behavioural (iCBT) self-help program for anxiety, supplemented with a smartphone application. The effect of added therapist support will also be studied.

Methods/Design

One hundred and fifty participants meeting diagnostic criteria for social anxiety disorder and/or panic disorder will be evenly randomised to either one of three study groups: 1, smartphone-supplemented iCBT with therapist support; 2, smartphone-supplemented iCBT without therapist support; or 3, an active waiting list control group with delayed treatment. Primary outcome measure will be the Generalised Anxiety Disorder 7-item self-rating scale. Secondary measures include other anxiety, depression and quality of life measures. In addition to pre- and post-treatment measurements, the study includes two mid-treatment (days 24 and 48) and two follow-up assessments (12 and 36 months) to assess rapid and long-term effects.

Discussion

To our knowledge, this is the first study to investigate the effectiveness of smartphone-supplemented iCBT for anxiety disorders. Hence, the findings from this trial will constitute great advancements in the burgeoning and promising field of smartphone-administered psychological interventions. Limitations are discussed.

Cognitive-behavioral therapy for the management of irritable bowel syndrome

Irritable bowel syndrome (IBS) is a common disorder, reported to be found in 5%-20% of the general population. Its management accounts for up to 25% of a gastroenterologist’s workload in the outpatient department, and the main symptoms are abdominal pain, bloating, and altered bowel habits. Despite a great amount of available pharmacological treatments aimed at a wide variety of gastrointestinal and brain targets, many patients have not shown adequate symptom relief. In recent years, there has been increasing evidence to suggest that psychological treatments, in particular cognitive-behavioral therapy (CBT), are effective for the management of IBS. This review discusses CBT for the management of IBS. CBT has proved to be effective in alleviating the physical and psychological symptoms of IBS and has thus been recommended as a treatment option for the syndrome.

Using the internet to provide psychodynamic psychotherapy

Over the last 15 years, there has been a substantial increase in research and clinical implementations of Internet-delivered, cognitive behavioral therapy (ICBT). Several studies on ICBT have been in the format of guided self-help where a therapist guides the patient throughout the whole treatment. ICBT is typically in the form of self-help material (e.g., text or video) which is provided to a client over the Internet with additional therapist contact by e-mail. ICBT has been shown to be effective for various conditions and, in some studies, has shown to be as effective as face-to-face cognitive behavioral therapy for mild to moderate depression, anxiety disorders, and somatic problems. Recently, the field has expanded to include other orientations including psychodynamic psychotherapy. Currently, there are three randomized controlled trials that have tested the efficacy of psychodynamic psychotherapy delivered in this format. The latest published trial focused on an affect-focused, psychodynamic psychotherapy delivered to a sample of participants with mixed depression and anxiety disorders. This article aims to provide a deeper understanding of the process of providing psychodynamic psychotherapy via the Internet. We will give a detailed description of our latest manual and show how psychotherapeutic work is conducted utilizing this text. Furthermore, we provide examples of dialogue between therapist and client from the online environment. Similarities and differences between psychodynamic psychotherapy delivered over the Internet and in face-to-face formats are discussed.

Psychotherapy for inflammatory bowel disease: a review and update

BACKGROUND

Psychotherapy may be a useful intervention for inflammatory bowel disease (IBD) patients. We systematically reviewed all randomized controlled trials that have been performed in psychotherapy for inflammatory bowel disease patients.

METHODS

Systematic searches were undertaken on 1 and 8 March, 2012 of studies of psychotherapy for IBD.

RESULTS

Eighteen studies (19 papers) were included in this review. Psychotherapy was found to have minimal effect on measures of anxiety, depression, QOL and disease progression although shows promise in reducing pain, fatigue, relapse rate and hospitalisation, and improving medication adherence. It may also be cost effective.

CONCLUSIONS

The effects of psychotherapy on IBD is mixed: future studies should determine whether patient screening or measuring different dependent variables improves outcomes and whether particular psychotherapies are superior over others.

Mindfulness online: an evaluation of the feasibility of a web-based mindfulness course for stress, anxiety and depression

OBJECTIVES

Face-to-face mindfulness interventions have been shown to significantly decrease perceived stress, anxiety and depression and research is beginning to show similar benefits for such courses delivered via the internet. We investigated the feasibility and effectiveness of an online mindfulness course for perceived stress, anxiety and depression.

DESIGN

A follow-up investigation of an online mindfulness course. Previous research examining the change in perceived stress showed promising results. Measures of anxiety and depression were added to the online mindfulness course and these were investigated as well as perceived stress using a new, larger sample.

PARTICIPANTS

Participants (N=273) were self-referrals to the online course who completed the outcome measure immediately before the course, upon course completion and at 1 month follow-up.

INTERVENTION

The programme consists of 10 sessions, guided meditation videos and automated emails, with elements of Mindfulness-Based Stress Reduction and Mindfulness-Based Cognitive Therapy, completed at a pace to suit the individual (minimum length 4 weeks).

PRIMARY AND SECONDARY OUTCOME MEASURES

The Perceived Stress Scale, the Generalised Anxiety Disorder Assessment-7 and the Patient Health Questionnaire-9 (for depression). Mindfulness practice was self-reported at automated time points upon login, once the exercises and sessions for each week were completed.

RESULTS

Perceived stress, anxiety and depression significantly decreased at course completion and further decreased at 1 month follow-up, with effect sizes comparable to those found with face-to-face and other online mindfulness courses and to other types of intervention, such as cognitive behavioural therapy for stress. The amount of meditation practice reported did affect outcome when controlling for baseline severity.

CONCLUSIONS

The online mindfulness course appears to be an acceptable, accessible intervention which reduces stress, anxiety and depression. However, there is no control comparison and future research is required to assess the effects of the course for different samples.

Prediction of symptomatic improvement after exposure-based treatment for irritable bowel syndrome

BACKGROUND

Several studies show that psychological treatments relieve symptoms for patients suffering from irritable bowel syndrome (IBS). However, there are no consistent findings that show what patient characteristics make a psychological treatment more or less likely to result in improvement. We have previously conducted a study of a newly developed internet-delivered cognitive behavioral therapy (ICBT) that emphasized exposure to IBS symptoms and IBS-related situations and reduced symptom-related avoidance. The study showed that the treatment led to improvement in IBS symptoms compared to a waiting list and that treatment gains were maintained over a 15-18 month follow-up period. The aim of the present study was to investigate several possible predictors of short- and long-term treatment outcome in terms of symptom improvement, based on data collected in the previously conducted treatment trial.

METHODS

Demographics, comorbid psychological distress, IBS-related fear and avoidance behaviors, and IBS-related disability were investigated as predictors of treatment outcome in the sample consisting of 79 participants diagnosed with IBS who had undergone 10 weeks of ICBT. Predictors that were significantly correlated with symptom levels at post-treatment and follow-up were entered into multiple regression analyses that controlled for pre-treatment symptom levels.

RESULTS

There were measures within each domain, i.e., comorbid psychological distress, IBS-related fear and avoidance behaviors, and IBS-related disability, with the exception of demographic data, that were correlated with the symptom levels at post-treatment and follow-up. However, when these were entered into a multiple regression analyses that controlled for pre-treatment levels, none remained a significant predictor of the post-treatment and follow-up symptomatic status.

CONCLUSIONS

The study did not find any individual characteristics that made patients more or less likely to respond to the exposure-based ICBT. The finding that comorbid psychological distress did not predict outcome is in accordance with previous studies. Reliable predictors for response to any type of psychological treatment for IBS remain to be established.

The Effectiveness of Internet-Based Mindfulness Interventions for Physical and Mental Illnesses

The rapid growth of information technologies, such as the internet, smartphones, and videoconferencing has improved the access to mindfulness therapies, which focus on enhancing one’s awareness of the present moment. This review paper attempts to provide an overall picture of the effectiveness of internet-based mindfulness therapies. After a brief introduction to the concept of mindfulness and a presentation of the literature search methods, this review focuses on the effectiveness of internet-based mindfulness therapies. Specifically, the review discusses the role of internet mindfulness therapies in the treatment of physical illnesses, such as chronic pain, irritable bowel syndrome, tinnitus, diabetes, and cardiovascular illness. Then, the applications of online mindfulness therapy to the treatment of mental illnesses, such as depression, stress, binge eating disorder, and suicidal ideation, are described. The review concludes with a discussion of potential future research directions.

Exploring patients' views of a cognitive behavioral therapy-based website for the self-management of irritable bowel syndrome symptoms

BACKGROUND

Cognitive behavioral therapy (CBT) has been shown to have positive effects on the management of irritable bowel syndrome (IBS) symptoms. A factorial pilot randomized placebo-controlled trial (called MIBS) tested the potential effectiveness of a self-management CBT-based website alongside two medications: methylcellulose and mebeverine, and a placebo. The results showed no significant differences in quality of life or symptom severity measures, but enablement and participant's global assessment of relief was higher in the website groups.

OBJECTIVE

To conduct a qualitative study nested within this trial, in order to explore patients' views and experiences of using the CBT-based website to facilitate self-management of IBS.

METHODS

Semistructured interviews were carried out with patients who had used the website with one session of nurse support (n=16) or the website alone (n=15) while participating in the MIBS trial. An inductive thematic analysis was conducted.

RESULTS

We identified three types of engagement with the CBT-based website. One group of participants, mostly in the website-only condition, had limited or no engagement with the website. One group engaged with the content and advice on practical lifestyle changes. The final group of participants engaged with the content and advice on psychological aspects related to IBS. Similarities and differences between these three groups are explored.

CONCLUSIONS

Teaching self-management techniques through a Web intervention was received positively by most of the participants. Concepts linked to cognitive aspects of CBT appeared to be harder for participants to engage with. Participants who received nurse support rated the cognitive aspects more positively, suggesting that some therapy support alongside the website should be considered. However, the Web format was preferred by some who favored anonymity as well as those who appreciated the accessibility and ease of use of this type of management. Suggestions on how to encourage engagement with Web interventions are discussed.

A systematic review of minimal-contact psychological treatments for symptom management in irritable bowel syndrome

OBJECTIVE

Psychological treatments are effective in alleviating symptoms of IBS but are not widely available. The need for wider dissemination of treatments has encouraged the development of 'minimal-contact' therapies requiring fewer resources than existing psychological treatments which rely on face-to-face contact.

METHOD

Using comprehensive search terms, the Embase, Medline and PsychInfo databases (all years) were searched.

RESULTS

Twelve studies--nine RCTs and three non-controlled preliminary studies - meeting inclusion criteria were reviewed and assessed for quality using objective criteria. Apart from one study of expressive writing, all interventions were based on cognitive (and/or) behavioural principles or hypnosis and tended to be adaptations of existing therapist-led interventions. Compared to control conditions, minimal-contact interventions were efficacious, the majority of studies showing statistically significant improvements by the end of treatment. For cognitive-behaviour-therapy-based interventions effects sizes were large. The two studies that compared minimal-contact with therapist-delivered interventions broadly suggest comparable outcomes between these modalities.

CONCLUSIONS

Minimal-contact cognitive-behavioural interventions show promise in the treatment of IBS. Because of the lower quality of studies of hypnosis and those involving interventions delivered entirely remotely, further support is needed before such approaches can be recommended for widespread use. More generally, future research should use representative samples, active control conditions, and intention to treat analysis. Nonetheless, existing high quality studies suggest that minimal-contact therapies may be a safe, effective means of achieving scaleability of psychological treatments for IBS.

Acceptance of tinnitus: validation of the tinnitus acceptance questionnaire

The concept of acceptance has recently received growing attention within tinnitus research due to the fact that tinnitus acceptance is one of the major targets of psychotherapeutic treatments. Accordingly, acceptance-based treatments will most likely be increasingly offered to tinnitus patients and assessments of acceptance-related behaviours will thus be needed. The current study investigated the factorial structure of the Tinnitus Acceptance Questionnaire (TAQ) and the role of tinnitus acceptance as mediating link between sound perception (i.e. subjective loudness of tinnitus) and tinnitus distress. In total, 424 patients with chronic tinnitus completed the TAQ and validated measures of tinnitus distress, anxiety, and depression online. Confirmatory factor analysis provided support to a good fit of the data to the hypothesised bifactor model (root-mean-square-error of approximation = .065; Comparative Fit Index = .974; Tucker-Lewis Index = .958; standardised root mean square residual = .032). In addition, mediation analysis, using a non-parametric joint coefficient approach, revealed that tinnitus-specific acceptance partially mediated the relation between subjective tinnitus loudness and tinnitus distress (path ab = 5.96; 95% CI: 4.49, 7.69). In a multiple mediator model, tinnitus acceptance had a significantly stronger indirect effect than anxiety. The results confirm the factorial structure of the TAQ and suggest the importance of a general acceptance factor that contributes important unique variance beyond that of the first-order factors activity engagement and tinnitus suppression. Tinnitus acceptance as measured with the TAQ is proposed to be a key construct in tinnitus research and should be further implemented into treatment concepts to reduce tinnitus distress.

Patient satisfaction after gut-directed hypnotherapy in irritable bowel syndrome

BACKGROUND

Gut-directed hypnotherapy is an effective treatment option for irritable bowel syndrome (IBS). However, clinical observations suggest that patient satisfaction with hypnotherapy is not always associated with improvement in IBS symptoms.

METHODS

We evaluated 83 patients with IBS treated with gut-directed hypnotherapy (1 h week(-1), 12 weeks). After the treatment period, patients reported their satisfaction with the treatment (ranging from 1 = not at all satisfied, to 5 = very satisfied) and completed questionnaires to assess IBS symptom severity, quality of life, cognitive function, sense of coherence, depression, and anxiety before and after treatment.

KEY RESULTS

After hypnotherapy improved IBS symptom severity, quality of life, cognitive function, and anxiety were seen. Thirty patients (36%) were very satisfied with the treatment and 57 (69%) patients scored 4 or 5 on the patient satisfaction scale. Patient satisfaction was associated with less severe IBS symptoms and better quality of life after the treatment. In a multiple linear regression analysis, only the quality of life domain sexual relations was independently associated with patient satisfaction after hypnotherapy, explaining 22% of the variance. Using 25% reduction of IBS symptom severity to define an IBS symptom responder, 52% of the responders were very satisfied with hypnotherapy, but this was also true for 31% in the non-responder group.

CONCLUSIONS & INFERENCES

Patient satisfaction with gut-directed hypnotherapy in IBS is associated with improvement of quality of life and gastrointestinal (GI) symptoms. However, other factors unrelated to GI symptoms also seems to be of importance for patient satisfaction, as a substantial proportion of patients without GI symptom improvement were also very satisfied with this treatment option.

Randomised clinical trial: symptoms of the irritable bowel syndrome are improved by a psycho-education group intervention

BACKGROUND

Evidence supports the effectiveness of cognitive behavioural approaches in improving the symptoms of the irritable bowel syndrome (IBS). Duration, cost and resistance of many patients towards a psychological therapy have limited their acceptance.

AIM

To evaluate the effectiveness of a psycho-educational intervention on IBS symptoms.

METHODS

Sixty-nine IBS patients (72% female) were randomised to an intervention or a wait-list control group. The IBS class consisted of education on a biological mind body disease model emphasising self-efficacy and practical relaxation techniques.

RESULTS

Patients in the intervention showed significant improvement on GI symptom severity, visceral sensitivity, depression and QoL postintervention and most of these gains were maintained at 3-month follow-up (Hedge's g = -0.46-0.77). Moderated mediation analyses indicated change in anxiety, visceral sensitivity, QoL and catastrophising due to the intervention had moderate mediation effects (Hedge's g = -0.38 to -0.60) on improvements in GI symptom severity for patients entering the trial with low to average QoL. Also, change in GI symptom severity due to the intervention had moderate mediation effects on improvements in QoL especially in patients with low to average levels of QoL at baseline. Moderated mediation analyses indicated mediation was less effective for patients entering the intervention with high QoL.

CONCLUSIONS

A brief psycho-educational group intervention is efficacious in changing cognitions and fears about the symptoms of the irritable bowel syndrome, and these changes are associated with clinically meaningful improvement in symptoms and quality of life. The intervention seems particularly tailored to patients with low to moderate quality of life baseline levels.

New treatments for IBS

IBS is a common disorder that affects approximately 5-20% of the populations of Western countries; the main symptoms are abdominal pain and erratic, altered bowel habits, often accompanied by bloating. Despite an array of available pharmacological and nonpharmacological treatments aimed at a wide variety of gastrointestinal and brain targets, many patients do not report adequate symptom relief. The effect of IBS on an individual can be enormous, and the societal and financial costs overall are high, which is indicative of an unmet need for effective IBS treatments. Intense research efforts are ongoing that range from the development of new molecules for pharmacological therapies to testing the utility of internet technology to facilitate widespread delivery of efficacious behavioural therapy. This Review discusses the latest treatments for IBS, including novel nonpharmacological and pharmacological approaches. We have included estimates of the number needed to treat and the number needed to harm for selected treatments. Emerging and potential future treatments are included, with the data supporting an optimistic view about the future of IBS therapeutics. The ability to optimize therapy by individualizing management whilst also avoiding harm remains the key to achieving the best possible outcomes with currently available therapeutics.

Effects on gastrointestinal transit and antroduodenojejunal manometry after gut-directed hypnotherapy in irritable bowel syndrome (IBS)

BACKGROUND

Gut-directed hypnotherapy is an effective treatment in irritable bowel syndrome (IBS) but little is known about the mechanisms of action. In this study we aimed to investigate the effects on gastrointestinal motility when treating IBS with gut-directed hypnotherapy.

METHODS

We randomized 90 patients with IBS, refractory to standard management to receive gut-directed hypnotherapy 1 h/week for 12 weeks or supportive treatment for the same time period. Eighty-one subjects (40 hypnotherapy, 41 controls) could be evaluated by one or more of the following investigations, both before and after the intervention: gastric emptying time, small bowel transit time, colonic transit time, and antroduodenojejunal manometry.

RESULTS

No significant differences in gastric emptying time, small bowel transit time, or colonic transit time was found when comparing the baseline and post-intervention measurements in the hypnotherapy group or in the control group. The same was true concerning the results of the antroduodenojejunal manometry. However, there was a numerical trend toward a higher number of migrating motor complexes at manometry and an accelerated gastric emptying time after hypnotherapy that did not reach statistical significance.

CONCLUSIONS

In this study, we were not able to find evidence for long-standing effects on gastrointestinal motility as a mediator of the effects on IBS when treating the condition with gut-directed hypnotherapy. Further research to understand the mechanism of action is needed.

Mindfulness-based interventions for physical conditions: a narrative review evaluating levels of evidence

Research on mindfulness-based interventions (MBIs) for treating symptoms of a wide range of medical conditions has proliferated in recent decades. Mindfulness is the cultivation of nonjudgmental awareness in the present moment. It is both a practice and a way of being in the world. Mindfulness is purposefully cultivated in a range of structured interventions, the most popular of which is mindfulness-based stress reduction (MBSR), followed by mindfulness-based cognitive therapy (MBCT). This paper begins with a discussion of the phenomenological experience of coping with a chronic and potentially life-threatening illness, followed by a theoretical discussion of the application of mindfulness in these situations. The literature evaluating MBIs within medical conditions is then comprehensively reviewed, applying a levels of evidence rating framework within each major condition. The bulk of the research looked at diagnoses of cancer, pain conditions (chronic pain, low back pain, fibromyalgia, and rheumatoid arthritis), cardiovascular disease, diabetes, human immunodeficiency virus (HIV)/acquired immune deficiency syndrome (AIDS), and irritable bowel syndrome. Most outcomes assessed are psychological in nature and show substantial benefit, although some physical and disease-related parameters have also been evaluated. The field would benefit from more adequately powered randomized controlled trials utilizing active comparison groups and assessing the moderating role of patient characteristics and program "dose" in determining outcomes.

Meditation over medication for irritable bowel syndrome? On exercise and alternative treatments for irritable bowel syndrome

Complimentary alternative treatment regimens are widely used in irritable bowel syndrome (IBS), but the evidence supporting their use varies. For psychological treatment options, such as cognitive behavioral therapy, mindfulness, gut-directed hypnotherapy, and psychodynamic therapy, the evidence supporting their use in IBS patients is strong, but the availability limits their use in clinical practice. Dietary interventions are commonly included in the management of IBS patients, but these are primarily based on studies assessing physiological function in relation to dietary components, and to a lesser degree upon research examining the role of dietary components in the therapeutic management of IBS. Several probiotic products improve a range of symptoms in IBS patients. Physical activity is of benefit for health in general and recent data implicates its usefulness also for IBS patients. Acupuncture does not seem to have an effect beyond placebo in IBS. A beneficial effect of some herbal treatments has been reported.

Electronic symptom reporting between patient and provider for improved health care service quality: a systematic review of randomized controlled trials. part 1: state of the art

BACKGROUND

Over the last two decades, the number of studies on electronic symptom reporting has increased greatly. However, the field is very heterogeneous: the choices of patient groups, health service innovations, and research targets seem to involve a broad range of foci. To move the field forward, it is necessary to build on work that has been done and direct further research to the areas holding most promise. Therefore, we conducted a comprehensive review of randomized controlled trials (RCTs) focusing on electronic communication between patient and provider to improve health care service quality, presented in two parts. Part 2 investigates the methodological quality and effects of the RCTs, and demonstrates some promising benefits of electronic symptom reporting.

OBJECTIVE

To give a comprehensive overview of the most mature part of this emerging field regarding (1) patient groups, (2) health service innovations, and (3) research targets relevant to electronic symptom reporting.

METHODS

We searched Medline, EMBASE, PsycINFO, Cochrane Central Register of Controlled Trials, and IEEE Xplore for original studies presented in English-language articles published from 1990 to November 2011. Inclusion criteria were RCTs of interventions where patients or parents reported health information electronically to the health care system for health care purposes and were given feedback.

RESULTS

Of 642 records identified, we included 32 articles representing 29 studies. The included articles were published from 2002, with 24 published during the last 5 years. The following five patient groups were represented: respiratory and lung diseases (12 studies), cancer (6), psychiatry (6), cardiovascular (3), and diabetes (1). In addition to these, 1 study had a mix of three groups. All included studies, except 1, focused on long-term conditions. We identified four categories of health service innovations: consultation support (7 studies), monitoring with clinician support (12), self-management with clinician support (9), and therapy (1). Most of the research (21/29, 72%) was conducted within four combinations: consultation support innovation in the cancer group (5/29, 17%), monitoring innovation in the respiratory and lung diseases group (8/29, 28%), and self-management innovations in psychiatry (4/29, 14%) and in the respiratory and lung diseases group (4/29, 14%). Research targets in the consultation support studies focused on increased patient centeredness, while monitoring and self-management mainly aimed at documenting health benefits. All except 1 study aiming for reduced health care costs were in the monitoring group.

CONCLUSION

RCT-based research on electronic symptom reporting has developed enormously since 2002. Research including additional patient groups or new combinations of patient groups with the four identified health service innovations can be expected in the near future. We suggest that developing a generic model (not diagnosis specific) for electronic patient symptom reporting for long-term conditions may benefit the field.

An integrated model of care for inflammatory bowel disease sufferers in Australia: development and the effects of its implementation

BACKGROUND

Psychological comorbidities are associated with poor outcome and increased healthcare utilization in patients with inflammatory bowel disease (IBD). However, a model of care addressing the biopsychosocial dimension of disease is not routinely applied in IBD. This review describes the development of such a model and the effects of its implementation in a hospital-based cohort of patients with IBD.

METHODS

Three different approaches were used: 1) collecting baseline epidemiological data on mental health comorbidities; 2) raising awareness of and targeting mental health problems; 3) examining the effects of the model implementation.

RESULTS

High rates of anxiety and depressive symptoms (36% and 13%, respectively) that are maintained over time were identified in IBD patients presenting at a metropolitan teaching hospital. Patients with documented psychological comorbidities were more likely to be hospitalized than those without (odds ratio [OR] = 4.13, 95% confidence interval [CI]: 1.25, 13.61). Improvements in disease activity, anxiety, depression, quality of life, and coping have been noted when cognitive-behavioral therapy (CBT) was provided to patients. A drop in the use of opiates (P = 0.037) and hospitalization rates (from 48% to 30%) in IBD patients has been noted as a result of introduction of the changed model of care. In addition, the mean total cost of inpatient care was lower for IBD patients than controls (US$12,857.48 [US$15,236.79] vs. US$ 30,467.78 [US$ 53,760.20], P = 0.005).

CONCLUSION

Our data to date suggest that an integrated model of care for patients with IBD may yield superior long-term outcomes in terms of medication use and hospitalization rates and reduce healthcare costs.

Absence of somatization in non-coeliac gluten sensitivity

OBJECTIVE

In contrast to coeliac disease (CD), the mechanism behind non-coeliac gluten sensitivity (NCGS) is unclear. The aims of the study were to measure the presence of somatization, personality traits, anxiety, depression, and health-related quality of life in NCGS individuals compared with CD patients and healthy controls, and to compare the response to gluten challenge between NCGS and CD patients.

MATERIAL AND METHODS

We examined 22 CD patients and 31 HLA-DQ2+ NCGS patients without CD, all on a gluten-free diet. All but five CD patients were challenged orally for 3 days with gluten; symptom registration was performed during challenge. A comparison group of 40 healthy controls was included. Patients and healthy controls completed questionnaires regarding anxiety, depression, neuroticism and lie, hostility and aggression, alexithymia and health locus of control, physical complaints, and health-related quality of life.

RESULTS

The NCGS patients reported more abdominal (p = 0.01) and non-abdominal (p < 0.01) symptoms after gluten challenge than CD patients. There were no significant differences between CD and NCGS patients regarding personality traits, level of somatization, quality of life, anxiety, and depressive symptoms. The somatization level was low in CD and NCGS groups. Symptom increase after gluten challenge was not related to personality in NCGS patients.

CONCLUSIONS

NCGS patients did not exhibit a tendency for general somatization. Personality and quality of life did not differ between NCGS and CD patients, and were mostly at the same level as in healthy controls. NCGS patients reported more symptoms than CD patients after gluten challenge.

Individually tailored internet-based treatment for young adults and adults with panic attacks: randomized controlled trial

Background

Previous studies on Internet-based treatment with minimal therapist guidance have shown promising results for several specific diagnoses.

Objective

To (1) investigate the effects of a tailored, therapist-guided, Internet-based treatment for individuals with reoccurring panic attacks, and (2) to examine whether people in different age groups (18–30 years and 31–45 years) would respond differently to the treatment.

Methods

We recruited 149 participants from an online list of individuals having expressed an interest in Internet treatment. Screening consisted of online questionnaires followed by a telephone interview. A total of 57 participants were included after a semistructured diagnostic interview, and they were randomly assigned to an 8-week treatment program (n = 29) or to a control condition (n = 28). Treatment consisted of individually prescribed cognitive behavior therapy text modules in conjunction with online therapist guidance. The control group consisted of people on a waitlist who later received treatment.

Results

All dependent measures improved significantly immediately following treatment and at the 12-month follow-up. The between-group effect size on the primary outcome measure, the Panic Disorder Severity Scale, was d = 1.41 (95% confidence interval 0.81–1.95) at posttreatment. The within-group effect size from pretreatment to 12-month follow-up was d = 1.66 (95% confidence interval 1.14–2.35). Age group had no effect, suggesting that age did not influence the outcome.

Conclusions

Tailoring an Internet-based treatment can be a feasible approach in the treatment of panic symptoms and comorbid anxiety and depressive symptoms. Younger adults benefit as much as adults over 30 years and up to 45 years of age.

Long-term effects of hypnotherapy in patients with refractory irritable bowel syndrome

OBJECTIVE

Gut-directed hypnotherapy is considered to be an effective treatment in irritable bowel syndrome (IBS) but few studies report the long-term effects. This retrospective study aims to evaluate the long-term perceived efficacy of gut-directed hypnotherapy given outside highly specialized hypnotherapy centers.

METHODS

208 patients, who all had received gut-directed hypnotherapy, were retrospectively evaluated. The Subjective Assessment Questionnaire (SAQ) was used to measure changes in IBS symptoms, and patients were classified as responders and non-responders. Patients were also asked to report changes in health-care seeking, use of drugs for IBS symptoms, use of alternative non-pharmacological treatments, and if they still actively used hypnotherapy.

RESULTS

Immediately after hypnotherapy, 103 of 208 patients (49%) were responders and 75 of these (73%) had improved further at the follow-up 2-7 years after hypnotherapy (mean 4 years). A majority of the responders still used hypnotherapy on a regular basis at follow-up (73%), and the responders reported a greater reduction in health-care seeking than non-responders. A total of 87% of all patients reported that they considered gut-directed hypnotherapy to be worthwhile, and this differed between responders and non-responders (100% vs. 74%; p < 0.0001).

CONCLUSION

This long-term follow-up study indicates that gut-directed hypnotherapy in refractory IBS is an effective treatment option with long-lasting effects, also when given outside highly specialized hypnotherapy centers. Apart from the clinical benefits, the reduction in health-care utilization has the potential to reduce the health-care costs.

Acceptability, effectiveness, and cost-effectiveness of internet-based exposure treatment for irritable bowel syndrome in a clinical sample: a randomized controlled trial

BACKGROUND

Internet-based cognitive behavior therapy (ICBT) has shown promising effects in the treatment of irritable bowel syndrome (IBS). However, to date no study has used a design where participants have been sampled solely from a clinical population. We aimed to investigate the acceptability, effectiveness, and cost-effectiveness of ICBT for IBS using a consecutively recruited sample from a gastroenterological clinic.

METHODS

Sixty-one patients were randomized to 10 weeks of ICBT (n = 30) or a waiting list control (n = 31). The ICBT was guided by an online therapist and emphasized acceptance of symptoms through exposure and mindfulness training. Severity of IBS symptoms was measured with the Gastrointestinal symptom rating scale--IBS version (GSRS-IBS). Patients in both groups were assessed at pre- and post-treatment while only the ICBT group was assessed 12 months after treatment completion. Health economic data were also gathered at all assessment points and analyzed using bootstrap sampling.

RESULTS

Fifty of 61 patients (82%) completed the post-treatment assessment and 20 of 30 patients (67%) in the ICBT group were assessed at 12-month follow-up. The ICBT group demonstrated significantly (p < .001) larger improvements on the IBS-related outcome scales than the waiting list group. The between group effect size on GSRS-IBS was Cohen's d = 0.77 (95% CI: 0.19-1.34). Similar effects were noted on measures of quality of life and IBS-related fear and avoidance behaviors. Improvements in the ICBT group were maintained at 12-month follow-up. The ICBT condition was found to be more cost-effective than the waiting list, with an 87% chance of leading to reduced societal costs combined with clinical effectiveness. The cost-effectiveness was sustained over the 12-month period.

CONCLUSIONS

ICBT proved to be a cost-effective treatment when delivered to a sample recruited from a gastroenterological clinic. However, many of the included patients dropped out of the study and the overall treatment effects were smaller than previous studies with referred and self-referred samples. ICBT may therefore be acceptable and effective for only a subset of clinical patients. Study dropout seemed to be associated with severe symptoms and large impairment. Objective and empirically validated criteria to select which patients to offer ICBT should be developed.
