A cross-cultural investigation of attachment style, catastrophizing, negative pain beliefs, and symptom severity in irritable bowel syndrome

Quality of Life and Its Psychosocial Predictors among Patients with Disorders of Gut-Brain Interaction: A Comparison with Age- and Sex-Matched Controls

The disorders of gut-brain interaction (DGBIs) are a heterogeneous group of chronic conditions that greatly reduce patients' quality of life (QoL). To date, biopsychosocial factors (such as gastrointestinal symptoms, alexithymia, and interpersonal problems) are believed to contribute to the development and maintenance of DGBIs, but their role in affecting patients' QoL is still under investigation. Out of 141 patients seeking treatment for their gastrointestinal symptoms, 71 were diagnosed with a DGBI (47 females, 66.2%; Mage: 41.49 ± 17.23 years) and were age- and sex-matched to 71 healthy controls (47 females, 66.2%; Mage: 40.45 ± 16.38 years) without any current gastrointestinal symptom or diagnosis. Participants completed a sociodemographic and clinical questionnaire and a survey investigating several psychosocial risk factors. We found greater symptom severity and difficulties in identifying feelings among patients compared to controls. Further, multiple linear regression analyses evidenced that, among patients, higher expressive suppression of emotions, difficulties in identifying feelings and interpersonal problems, and a lower cognitive reappraisal of emotions predicted lower QoL. Data suggest that the QoL of patients with DGBIs is affected not only by common risk factors (e.g., interpersonal problems) but also by specific difficulties in processing and regulating emotions. The implications of these findings are discussed.

Anxiety and depression in Indian patients with irritable bowel syndrome: A meta-analysis

BACKGROUND

Functional gastrointestinal disorders (FGIDs), including irritable bowel syndrome (IBS), are associated with psychological abnormalities, such as anxiety and depression. Though the data on this are plenty in global literature, Indian data are sparse. We performed a systematic review and meta-analysis of Indian data on anxiety and depression among patients with IBS to estimate their pooled prevalence and to identify the shortcomings so that future areas of research can be identified.

METHOD

A comprehensive literature search was performed for studies applying tests for psychological issues in patients with IBS. After applying prospectively decided exclusion criteria, the eligible papers were examined using a meta-analysis approach for the prevalence of anxiety and depression in IBS patients using different tests. The odds ratios (OR) of anxiety and depression among subjects with IBS were calculated compared to controls.

RESULTS

Of seven studies (590 IBS patients and 1520 controls) included in the meta-analysis, the pooled OR of anxiety was 8.060 (95% confidence interval [CI] 4.007-16.213) as compared to controls (random-effect model). The pooled OR of depression was 7.049 (95% CI 3.281-15.147) compared to controls (random-effect model). There was significant heterogeneity in the included studies.

CONCLUSION

The current meta-analysis shows that the patients with IBS from India have eightfold greater risks of anxiety and sevenfold greater risks of depression than the controls. However, most of these data were from tertiary urban centers, and hence, there might be recruitment bias over-estimating the frequency.

Characteristics of, and natural history among, individuals with Rome IV functional bowel disorders

BACKGROUND

Little is known about the natural history of functional bowel disorders using Rome IV criteria. We examined these issues in a longitudinal follow-up study.

METHODS

We collected complete demographic, gastrointestinal symptom, and psychological comorbidity data at baseline from 1372 adults who met Rome IV criteria for one of the five functional bowel disorders. At 12 months, we collected data regarding gastrointestinal symptoms, psychological comorbidity, consultation behavior, and treatment commenced. We examined prognosis and stability of all five functional bowel disorders.

KEY RESULTS

At baseline, 811 (59.1%) individuals met Rome IV criteria for irritable bowel syndrome (IBS), 76 (5.5%) functional constipation (FC), 199 (14.5%) functional diarrhea (FDr), 130 (9.5%) functional abdominal bloating or distension (FABD), and 156 (11.4%) unspecified functional bowel disorder (UFBD). In total, 782 (57.0%) were successfully followed up. Individuals with IBS at baseline were significantly more likely to report symptoms compatible with anxiety, depression, or somatoform-type behavior (p < 0.001 for all analyses) at baseline and follow-up compared with those with the other four functional bowel disorders. IBS was the most stable functional bowel disorder; 319 (70.6%) of 452 participants still met criteria for IBS at 12 months, compared with 14 (34.1%) of 41, 43 (35.5%) of 121, 26 (33.8%) of 77, and 37 (40.7%) of 91 for FC, FDr, FABD, and UFBD, respectively (p < 0.001).

CONCLUSIONS AND INFERENCES

Individuals with Rome IV-defined IBS exhibited higher levels of anxiety, depression, or somatoform-type symptom reporting. IBS was the most stable and the likeliest disorder that the other four functional bowel disorders would fluctuate to.

Hypnotherapy for persons with Irritable Bowel Syndrome: A three-arm randomized controlled trial

The current study sought to (1) compare the efficacies of Ericksonian hypnotherapy, traditional hypnotherapy, and educational talk in treating irritable bowel syndrome (IBS), and to (2) evaluate the impacts of hypnotic susceptibility on participants' responses to hypnotherapy. The study adopted a three-arm randomized controlled trial design and achieved an effective sample size of 144. Self-reported psychological questionnaires were used to assess participants' IBS symptom severity, health-related quality of life, and coping patterns at baseline, immediately post-intervention, and 3 months after intervention. The evaluation focused primarily on IBS symptom severity and health-related quality of life, as well as on the illness coping patterns of symptom catastrophizing and symptoms-related social hypervigilance.The findings showed that significant improvements in IBS symptom severity occurred in all three types of study groups immediately after completion of the intervention (p < .05, η_ρ² = .20). However, only the traditional hypnotherapy groups and the Ericksonian hypnotherapy groups still had a notably significant decrease in symptoms 3 months after the intervention, whereas the educational talk groups had dropped back to pre-treatment symptom levels at the 3-month follow-up. The amplitude of change of symptom catastrophizing in the traditional hypnotherapy groups was stronger than that in the Ericksonian hypnotherapy groups after completion of the intervention, and the two types of hypnotherapy groups were significantly lower in symptom catastrophizing both immediately after the intervention and also 3 months post-intervention (p < .001, η_ρ² = .17). The other coping mechanism studied, symptoms-related social hypervigilance, showed a significant decline only in the Ericksonian hypnotherapy groups (ps < .001, η_ρ² = .45). Interestingly, in the traditional hypnotherapy groups, persons with higher hypnotic susceptibility showed significant improvement in symptom severity, health-related quality of life, and coping patterns following treatment. Notably, the effects from Ericksonian hypnotherapy for IBS diverged from the effects from traditional hypnotherapy. Finally, both Ericksonian hypnotherapy and traditional hypnotherapy appeared to have greater positive effects than educational talk did, but at different levels.

The Validity of Somatic Symptom Disorder in Patients With Gastrointestinal Complaints

BACKGROUND AND GOAL

The current diagnostic concept of somatic symptom disorder (SSD) aims to capture psychological burden due to bodily complaints independent of the medical cause. The aim of this study was to compare patients with chronic gastrointestinal (GI) complaints with SSD (SSD+) and without SSD (SSD-) along sociodemographic, clinical, and psychological characteristics.

STUDY

This cross-sectional study included 199 patients (n=92 SSD+ and n=107 SSD-) with distressing and chronic abdominal/lower GI complaints (≥6 mo) recruited from several primary, secondary, and tertiary medical care units. SSD+ patients were separated from SSD- patients by psychobehavioral positive criteria. Psychological distress (somatization, depression, anxiety, and illness anxiety) and risk factors (adverse childhood experiences, insecure attachment, mentalizing capacity, and levels of personality functioning) were measured. Nonparametric group comparisons were performed to analyze the differences of sociodemographic, clinical, and psychological characteristics between SSD+ and SSD- patients.

RESULTS

About half of the SSD+ patients had a functional GI disorder and a third had an inflammatory bowel disease. SSD+ patients reported higher GI pain severity, higher health-related and work-related impairment, and higher psychological distress, especially illness anxiety, as well as higher mentalizing and personality functioning deficits.

CONCLUSIONS

Overall, psychobehavioral positive criteria of SSD seem to be a valid identifier of patients exhibiting a high psychological burden, independent of the medical explanation of the GI complaints. There is a substantial overlap of SSD and general mental burden, but also evidence for a specific disease entity.

Psychological aspects in early adjustment after severe burn injury

Burn injury is one of the most serious traumatic events with possible psychological and psychosocial consequences. Health status perception is one of the main health outcomes. The severity of psychological symptoms does not always correlate with that of the burn injury, suggesting that early screening for psychological vulnerabilities may be beneficial. The aim of our study was to identify the personality, clinical, and sociodemographic characteristics related to patient´s subjective perception of health, depression, and anxiety, in a sample of 52 adult patients with severe burn injury shortly before discharge from specialty Burn clinic. Subjective health perception was predicted by depression (β = -.143, t(47) = -3.94, P < .001) and neuroticism (β = -.106, t(43) = -4.83, P < .001), and it correlated positively with extraversion (r = .2858, P = .0465) and conscientiousness (r = .3663, P = .0096). Depression was predicted by neuroticism (F(1,49) = 18.4; P < .001) and correlated with attachment avoidance (r = .29, P = .0383) and negatively with extraversion (r = -.32, P = .0220). Anxiety was related to attachment anxiety (F(1,49) = 4.25; P = .045), neuroticism (F(1,49) = 15.75; P < .001), and agreeableness (r = -.36, p = .0101). Unemployed patients experienced higher levels of depression and anxiety. This research suggests that personality traits and adult attachment may play an important role in the acute phase of the recovery from a severe burn injury. These findings can be relevant for early intervention and holistic rehabilitation.

Expectations of IBS patients concerning disease and healthcare providers: Results of a prospective survey among members of a French patients' association

BACKGROUND AND AIMS

IBS patients have an impaired quality of life (QoL) and feel dissatisfaction with medical care. We aim to describe the expectations of members of the French Association of IBS patients (APSSII) concerning health care providers (HCPs) and a patients' organization.

PATIENTS AND METHODS

From January to June 2013, APSSII members were asked to answer questionnaires on their expectations and experiences concerning IBS and HCP.

RESULTS

222/330 (67%) responded (women: 68.5%, 46.5±17.7 years, disease duration: 8.8±0.7 years, IBS-D 33.6%, IBS-C 26.7%, IBS-M 38.2%. IBS-SSS>300 in 53% and HAD score>19 in 45%). QoL impairment was correlated with disease severity and HAD score (r=-0.707 and r=-0.484, P<0.001 respectively), but not with IBS subtype. Expectations for IBS were "improved health", "better information on causes and treatments" (94%) and "better disease recognition" (86%). A significant gap was observed between expectations and experiences with HCPs. Better information, less isolation, recognition of the disease and a decrease in medical expenses were the main expectations for joining a patients' organization.

CONCLUSIONS

French IBS patients have a severe disease with a significant psychological impact and impaired QoL in half of the patients, certain unsatisfied expectations concerning HCP and high expectations in joining a patients' organization.

Does symptom activity explain psychological differences in patients with irritable bowel syndrome and inflammatory bowel disease? Results from a multi-center cross-sectional study

OBJECTIVE

Irritable bowel syndrome (IBS) and inflammatory bowel diseases (IBD) have similar symptoms and are affected by psychological factors via gut-brain-interactions. However, previous studies on IBS and IBD showed inconsistent results regarding psychological factors, potentially because they failed to consider the impact of symptom activity. The aim of this study was 1) to compare psychological distress and psychological risk factors among patients with IBS, IBD and healthy controls (HC), and 2) to assess the impact of symptom activity.

METHODS

A controlled cross-sectional study was conducted. Patients with IBS and IBD were recruited in several primary, secondary, and tertiary medical care units between 02 and 12/2017 in Germany. Overall, 381 matched participants (127/group, 63% female) were included. For the second analyses, patients with IBD were distinguished in patients with active (n = 93) and non-active (n = 34) symptoms. Psychological distress (somatization, depression, anxiety, and illness anxiety) and risk factors (adverse childhood experiences, attachment style, and mentalizing capacity) were measured.

RESULTS

Patients with IBS showed higher psychological distress and more psychological risk factors than patients with IBD and HC. However, patients with IBD and active symptoms showed similar psychological distress than patients with IBS, except for lower illness anxiety (p < .001, η² = 0.069).

CONCLUSION

With the exception of higher illness anxiety in IBS patients, differences in psychological factors between patients with IBS and IBD were more strongly associated with symptom activity than with the underlying diagnosis. Therefore, this study challenges previous concepts of distinguishing functional and organic gastrointestinal diseases, but highlights the role of symptom activity and illness anxiety.

The role of psychological factors in pediatric functional abdominal pain disorders

BACKGROUND

Pediatric functional abdominal pain disorders (FAPDs) are disorders of brain-gut dysregulation. Psychological factors are known to be related to etiology, maintenance, and exacerbation of pediatric FAPDs. With the evolving literature in the past two decades, a better understanding has emerged of precisely which psychological factors are associated with childhood FAPDs.

PURPOSE

This narrative literature review summarizes the literature of both child and parent psychological factors in pediatric FAPD. Where anxiety and depression were major targets in the older literature, present-day focus is increasingly on pain-specific cognitions and coping strategies including disease threat and catastrophizing. In addition, parental reaction to a child's pain is increasingly recognized as an important moderator of a child's outcomes and has become an area for clinical intervention. Screening for these factors and integrative treatment approaches are recommended in childhood FAPD.

Transcutaneous electric nerve stimulation over acupoints for patients with diarrhea-predominant irritable bowel syndrome: Protocol for systematic review and meta-analysis

BACKGROUND

At present, drug therapy for diarrhea-predominant irritable bowel syndrome (IBS-D) has made great progress; however, it does not often produce a satisfying curative effect. Transcutaneous electric nerve stimulation over acupoints (Acu-TENS) might be more effective in improving patient's symptoms and producing fewer side-effects as a result.Although with a great progress of the drug therapy for IBS-D, it is often hard to achieve its satisfactory curative effect. Acu-TENS that may be effective to improve patients' symptoms and fewer side-effects will be sought. There is no systematic review concerning the efficacy of Acu-TENS for IBS-D published. Therefore, this review aims to systematically evaluate the efficacy of Acu-TENS on IBS-D.

METHODS

Four English (PubMed, EMBASE, The Cochrane Library, Web of Science) and 4 Chinese electronic databases (Biomedical Literature Database, CNKI, VIP, Wanfang Database) will be searched from their inception to November 26, 2018. Randomized controlled trials that evaluated the effect of Acu-TENS on patients with IBS-D will be included. The primary outcome measures will include average weekly stool frequency, visual analog scale (VAS), and the Bristol scale. The secondary outcome measures will include the MOS 36-item short-form health survey (SF-36), IBS Quality of Life Questionnaire (IBS-QOL), severity of IBS symptoms (IBS-SSS), and rectal perception. Quality evaluation and data extraction will be independently undertaken, respectively. The data from the eligible trials will be analyzed by RevMan5.3.

RESULTS

For patients with IBS-D, this systematic review will provide evidences related to the efficacy of Acu-TENS in these evaluation aspects, stool frequency, VAS and the Bristol scale, SF-36, IBS-QOL, IBS-SSS, and rectal perception.

CONCLUSION

This evidence may be useful to medical workers with regard to the use of Acu-TENS in the treatment of IBS-D.PROSPERO registration number: PROSPERO CRD442018109294.

The association of catastrophizing with quality-of-life outcomes in patients with irritable bowel syndrome

Background

Catastrophizing is a cognitive process characterized by a propensity to concentrate on and magnify the value of an actual or anticipated painful stimulus and negatively assesses one’s ability to cope. Catastrophizing is an important predictor of pain-related outcomes. A cornerstone symptom of irritable bowel syndrome (IBS) is abdominal pain or discomfort. Also individuals with IBS have been reported to have a tendency to catastrophize. In a sample of individuals who suffer from IBS, we hypothesized that those individuals who catastrophize (catastrophizers) would have worse outcomes as compared to those who do not catastrophize (non-catastrophizers).

Methods

One hundred and one adults with IBS (79% female, mean age 42 years, 97% Caucasian) were recruited from outpatient clinics and data were collected through self-report measures. Catastrophizing was measured with the catastrophizing subscale of the Coping Strategies Questionnaire, illness representations were measured with The Revised Illness Perception Questionnaire (IPQ-R), psychological distress was measured with the Brief Symptom Inventory 18 (BSI-18), and health-related quality of life was measured using the Irritable Bowel Syndrome-Quality of Life (IBS-QOL) measure. Descriptive statistics, correlations, and multiple linear regression analyses were completed to describe participants, the associations of the variables of interest, and the unique relationship between psychosocial variables and HRQOL.

Results

Overall, participants reported poor HRQOL (M = 63.32, range 0–100). Catastrophizers differed significantly on IBS-QOL from non-catastrophizers (M = 48.98 vs. non-catastrophizers M = 78.53; p < 0.001), BSI-18 (M = 21.35 vs. non-catastrophizers M = 6.76; p < 0.001), and IPQ-R, specifically the consequences (M = 21.75 vs. non-catastrophizers M = 17.20; p < 0.001) and emotional representations (M = 20.90 vs. non-catastrophizers M = 15.43; p < 0.001). Catastrophizing was positively correlated with the consequences (r = .54; p < 0.01) and emotional representations (r = .65; p < 0.01) and negatively correlated with total HRQOL (r = −0.76; p < 0.01).

Conclusion

The findings indicated that participants who catastrophized reported worse psychosocial and functional outcomes. Thus, catastrophizing, in addition to psychological distress variables, may be an important factor to address in optimizing health outcomes in individuals with IBS. In addition, illness perceptions were strongly related to catastrophizing and HRQOL; assessment and integration of illness perceptions as well as catastrophizing into the management of individuals who suffer with IBS may maximize the health outcomes.

Anxiety and IBS revisited: ten years later

Background and aim

Irritable bowel syndrome (IBS) has been associated with high prevalence of psychological and psychiatric disorders. However, the association between IBS and each of its subtypes (diarrhea IBS-D, constipation IBS-C, mixed IBS-M) with anxiety still remains unclear. The purpose of this study was to perform a comparative analysis of the association between anxiety and IBS on a period of ten years.

Methods

PubMed was searched for studies analyzing IBS and anxiety, published at 10 years interval. The study presents a comparative analysis of the articles that were published between 2003–2005 and 2013–2015, investigating the correlation between anxiety and IBS.

Results

The initial search identified 220 articles, from which 156 were published between 2013 and 2015, and 64 were published between 2003 and 2005. Of these articles, 15 articles were included in the review. Out of these 15 articles, 10 articles analyzed the correlation between anxiety-depression status in IBS patients using specific questionnaires, 2 articles analyzed genetic variables in IBS, 1 article analyzed serotonin and monoamine oxidase levels in IBS, 1 article analyzed serum levels of IL-1β and IL-10 in IBS, 1 article analyzed somatostatin and vasoactive intestinal peptide levels in IBS. The result was a review of 15 studies that analyzed the association between IBS and anxiety.

Conclusions

IBS is a heterogeneous disorder caused by numerous psychological, immunological, infectious, endocrine and genetic factors. In recent years, the number of studies concentrating on genetic factors, cytokines and hormones has increased in comparison with the 2003–2005 period, when clinical investigation, using mainly questionnaires was the essential method. Also, the total number of papers investigating anxiety and IBS, considerably increased. The recent studies have confirmed the fact that IBS symptoms are often exacerbated during stressful events and the psychiatric treatment has a positive effect on gastro-intestinal symptomatology.
