“…For this purpose, it underwent translation into German, independent back-translation into English, and comparison of both English versions for equality by an English native speaker. A translation into German and validation by another group was published later [ 75 ] and proved to be equivalent. Sound psychometric properties with regard to sensitivity, specificity and reproducibility were reported [ 75 ].…”

BackgroundResilience refers to a class of variables that are highly relevant to wellbeing and coping with stress, trauma, and chronic adversity. Despite its significance for health, resilience suffers from poor conceptual integration. Irritable bowel syndrome (IBS) is a functional disorder with altered psychological stress reactivity and a brain-gut-microbiota axis, which causes high levels of chronic strain. Gut-directed Hypnotherapy (GHT) is a standardized treatment for IBS aimed at improving resilience. An improvement of resilience as a result of GHT has been hypothesized but requires further investigation. The aims of the study were to validate the construct and develop an integrational measure of various resilience domains by dimensional reduction, and to investigate changes in resilience in IBS patients after GHT.MethodA total of N = 74 gastroenterology outpatients with IBS (Rome III criteria) were examined in 7 resilience domains, quality of life, psychological distress and symptom severity. Of these, n = 53 participated in 7 to 10 GHT group sessions (Manchester protocol). Post-treatment examinations were performed on average 10 months after last GHT session.ResultsResilience factors proved to be unidimensional in the total sample. Greater resilience (composite score of resilience domains) and quality of life, and lower symptom severity and psychological distress were found after treatment (n = 16). Similar differences were present in cross-sectional comparisons of n = 37 treated vs. n = 37 untreated patients.ConclusionResilience factors share a common psychological dimension and are functionally connected. The absence of maladaptive behaviours contributes to resilience. Improvements in resilience after hypnotherapy with parallel increases in quality of life and reduced psychological distress and symptom severity were observed. Independent replications with larger sample sizes and randomized controlled trials are needed.

“…Based on validated cut-off values, three IBS severity subgroups can be distinguished: mild (IBS-SSS: 75–175), moderate (IBS-SSS: 175–300) and severe (IBS-SSS:>300). The German version of this questionnaire was validated by Betz et al 16 , and the total score was computed in accordance with the manual.…”

Is body mass index associated with symptom severity and health-related quality of life in irritable bowel syndrome? A cross-sectional study

et al. 2018

ObjectiveThe aim of this study was to describe the body mass index (BMI) distribution in patients with irritable bowel syndrome (IBS) based on the Rome III criteria and to evaluate the association of BMI with symptom severity and quality of life (QOL).MethodsA cross-sectional study was carried out in patients visiting our outpatient functional gastrointestinal disorders specialty clinic. IBS diagnosis was made based on Rome III criteria. IBS symptom severity was investigated using the IBS severity score system. QOL was assessed using the Short Form 36 Health Survey, which consists of physical health and mental health.Results366 patients (252 women) who fulfilled Rome III criteria and provided complete BMI data (23.90±5.22 kg/m2) were included. Overall, 59.0% of patients with IBS were in the normal weight range, 30.3% were overweight or obese, and 10.7% were underweight. Both physical and mental health decreased significantly with the severity of symptoms (all p<0.01), while controlling for several covariates (age, gender, family status, education status and IBS subtypes). Obesity and symptom severity (β=−0.177,△R2=0.037, p<0.01; β=−0.387,△R2=0.147, p<0.01) were significant negative factors that influencing physical health. Symptom severity (β=−0.301,△R2=0.084, p<0.01) was significant negative factor that influencing mental health. However, BMI didn’t account for additional variance in mental health (p>0.05).ConclusionBeing overweight is a common phenomenon in patients with IBS regardless of IBS subtype. The association between QOL and symptom severity followed a negative dose-response pattern. Patients with higher BMI, especially obese patients, were more frequently in poor physical health. However, this kind of relationship was not found in BMI and mental health.

“…It consists of three single questions that allow three different answers and a 100-point VAS on which 0 reflects the worst and 100 the best possible condition. All questionnaires have been used in German language before [26, 27]. In addition, stool frequency was quantified before and at the end of the study.…”

PurposeIrritable bowel syndrome (IBS) is common but therapies are unsatisfactory. Food is often suspected as cause by patients, but diagnostic procedures, apart from allergy testing, are limited. Based on the hypothesis of non-celiac wheat sensitivity (WS) in a subgroup of IBS patients, we tested the long-term response to a gluten-free diet (GFD) and investigated HLA-DQ2 or -DQ8 expression as a diagnostic marker for WS in diarrhea-dominant (IBS-D) and mixed-type IBS (IBS-M).MethodsThe response to a GFD served as reference test for WS and HLA-DQ2/8 expression was determined as index test. Patients were classified as responders if they reported complete or considerable relief of IBS symptoms on at least 75 % of weeks over a 4-month period of gluten-free diet. Established questionnaires (IBS-Quality of Life (IBS-QoL), IBS Symptom Severity Scale (IBS-SSS), European Quality of Life-5 Dimensions (EQ-5D)) were used for secondary outcome measures.ResultsThirty-five patients finished the study. Of these, 12 (34 %) were responders and classified as having WS (95 % CI 21–51 %). HLA-DQ2/8 expression had a specificity of 52 % (95 % CI 33–71 %) and sensitivity of 25 % (95 % CI 8–54 %) for WS. Responders showed improvement in quality of life and symptom scores. At 1-year follow-up, all responders and 55 % of non-responders were still on GFD and reported symptom relief.ConclusionUsing strict criteria as recommended for IBS studies, about one third of patients with IBS-D or IBS-M are wheat sensitive, with a similar proportion in both IBS types. Expression of HLA-DQ2/8 is not useful as diagnostic marker for WS. Long-term adherence to a GFD is high and can sustain symptomatic improvement.Electronic supplementary materialThe online version of this article (doi:10.1007/s00384-016-2663-x) contains supplementary material, which is available to authorized users.
