Positive psychological well-being and clinical characteristics in IBS: A systematic review

The role of cognitive emotion regulation strategies in predicting the resilience, symptom severity, and quality of life of patients with irritable bowel syndrome

BACKGROUND

Psychosocial stressors contribute to the development of irritable bowel syndrome (IBS) and exacerbate the symptoms. The capability to cope with stress is an essential element in the management of IBS. This study assessed nine cognitive emotion regulation strategies (CERS) and their role in predicting symptom severity, quality of life (QOL), and resilience in IBS subjects.

METHODS

The scores regarding nine subscales of CERS were obtained by cognitive emotion regulation questionnaire (CERQ) and compared between study patients based on the severity and subtypes of IBS using one-way ANOVA. To evaluate the predictive role of CERS, logistic regression was performed. The correlation between CERS and the QOL was assessed by Pearson correlation analysis. The score of resilience was measured by Connor-Davidson Resilience Scale (CD-RISC).

RESULTS

We recruited 100 patients diagnosed with IBS based on ROME IV criteria. Among nine subscales of CERS, patients with more severe symptoms scored higher in catastrophizing (p < 0.001) and blaming others (p = 0.015) while lower in positive reappraisal (p = 0.028). Blaming others was the only predictor of resilience and severity of IBS in our patients (odds ratio (OR): -2.103, p=0.028, and OR:1.715, p = 0.049, respectively). We observed significant negative correlations between the quality of life and rumination (r= -0.202, p=0.044), self-blame (r= -0.241, p=0.016), catastrophizing (r= -0.342, p<0.001), and blaming others (r= -0.219, p=0.028).

CONCLUSION

Maladaptive strategies are more common in IBS patients with more severe symptoms and have negative correlations with the QOL. Blaming others has the potential to predict the resilience and severity of symptoms in IBS patients.

Psychological distress in individuals with irritable bowel syndrome: the roles of body image and self-criticism

Objective

Irritable bowel syndrome (IBS) is a prevalent gastrointestinal disorder associated with reduced quality of life and psychological distress (PD) including anxiety and depression. The mechanisms linking IBS to PD are unclear. Previous studies showed that body image and self-criticism may be contributory factors. Thus, the objective of this study was to test the potential mediating roles of these factors in the relationship between IBS and PD.

Method

507 adults participated, including 142 with IBS (Mean age = 31.9, SD = 11.7), and 365 healthy peers (Mean age = 26.2, SD = 6.4), ranging in age from 18 to 75. The majority of participants were women (78%). Self-report measures assessed IBS status, body appreciation, body dissatisfaction, self-criticism, sociodemographic status, depression, and anxiety. Path analysis tested the hypothesized mediation model.

Results

IBS participants reported greater PD, lower body appreciation, higher body dissatisfaction, and higher self-criticism than controls. Body appreciation and self-criticism sequentially mediated the link between IBS status and both depression and anxiety. IBS was associated with reduced body appreciation, which in turn was linked to heightened self-criticism, thereby leading to elevated psychological distress.

Conclusion

Results suggest IBS negatively impacts body image appreciation, fostering self-critical judgments that exacerbate psychological symptoms. This study is the first to demonstrate a significant association between body appreciation and IBS, specifically highlighting this relationship. Findings clarify the psychosocial pathways at play in the comorbidity of mental health issues in IBS. Physicians and other health professionals are advised to detect women with IBS who are distressed, and to offer them appropriate intervention to prevent downstream consequences.

The role of repetitive transcranial magnetic stimulation therapy in functional bowel disease

Objective

This study investigates the effectiveness of repetitive transcranial magnetic stimulation (rTMS) as a biophysical therapy for alleviating symptoms of functional bowel disorder (FBD) and associated psychological symptoms by targeting the brain-gut axis.

Methods

We conducted a comparative analysis involving 226 subjects, comprising the FBD group (n = 113) and a healthy control group (n = 113). Within the FBD group, participants were further divided into those who received rTMS therapy (FBD treatment group, n = 63) and those who did not (FBD control group, n = 50). The FBD treatment group was subcategorized based on the number of rTMS treatments received. We evaluated various factors, including gender, age, monthly household income, daily activity level, and sleep quality, as potential risk factors for FBD. Severity assessments of FBD and associated symptoms (constipation, anxiety, depression, and somatization disorders) were conducted using validated scales before and after treatment.

Results

Our findings revealed a higher incidence of FBD in women, with most cases emerging at age 50 or older. We identified lower monthly household income, reduced daily activity levels, and poorer sleep quality as factors associated with a higher likelihood of FBD. FBD patients exhibited higher scores for constipation, anxiety, depression, and somatization disorders compared to healthy controls. rTMS therapy was effective in reducing gastrointestinal symptoms, anxiety, depression, and somatization disorders among FBD patients. Notably, the extent of improvement was positively correlated with the number of rTMS sessions. No adverse effects were observed during the study.

Conclusion

Our study underscores the efficacy of biophysical therapy, specifically repetitive transcranial magnetic stimulation, in mitigating FBD symptoms and associated psychological distress. The treatment's effectiveness is positively linked to the frequency of rTMS sessions.

Positive Psychological Well-Being in Hematopoietic Stem Cell Transplantation Survivors

Positive thoughts and emotions contribute to overall psychological health in diverse medical populations, including patients undergoing HSCT. However, few studies have described positive psychological well-being (eg, optimism, gratitude, flourishing) in patients undergoing HSCT using well-established, validated patient-reported outcome measures. We conducted cross-sectional secondary analyses of baseline data in 156 patients at 100 days post-HSCT enrolled in a randomized controlled trial of a psychological intervention (ClinicalTrials.gov identifier NCT05147311) and a prospective study assessing medication adherence at a tertiary care academic cancer center from September 2021 to December 2022. We used descriptive statistics to outline participant reports of positive psychological well-being (PPWB) using validated measures for optimism, gratitude, positive affect, life satisfaction, and flourishing. The participants had a mean age of 57.4 ± 13.1 years, and 51% were male (n = 79). Many, but not all, participants reported high levels of PPWB (ie, optimism, gratitude, positive affect, life satisfaction, and flourishing), defined as agreement with items on a given PPWB measure. For example, for optimism, 29% of participants did not agree that "overall, I expect more good things to happen to me than bad." Aside from life satisfaction, mean PPWB scores were higher in the HSCT population than in other illness populations. Although many patients with hematologic malignancies undergoing HSCT report high levels of PPWB, a substantial minority of patients reported low PPWB (i.e., no agreement with items on a given PPWB measure). Because PPWB is associated with important clinical outcomes in medical populations, further research should determine whether an intervention to promote PPWB can improve quality of life in HSCT recipients.

Peer support interventions in patients with kidney failure: A systematic review

BACKGROUND

Peer support has been associated with improved health-related outcomes (e.g., psychological well-being and treatment adherence) among patients with serious, chronic conditions, including kidney disease. Yet, there is little existing research evaluating the effects of peer support programs on health outcomes among patients with kidney failure being treated with kidney replacement therapy.

METHODS

Following Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines, we conducted a systematic review using five databases to assess the effects of peer support programs on health-related outcomes (e.g., physical symptoms, depression) among patients with kidney failure undergoing kidney replacement therapy.

RESULTS

Peer support in kidney failure was assessed across 12 studies (eight randomized controlled trials, one quasi-experimental controlled trial, and three single-arm trials) with 2893 patients. Three studies highlighted the links between peer support and improved patient engagement with care, while one found peer support did not significantly impact engagement. Three studies showed associations between peer support and improvements in psychological well-being. Four studies underscored the effects of peer support on self-efficacy and one on treatment adherence.

CONCLUSIONS

Despite preliminary evidence of the positive associations between peer support and health-related outcomes among patients with kidney failure, peer support programs for this patient population remain poorly understood and underutilized. Further rigorous prospective and randomized studies are needed to evaluate how peer support can be optimized and incorporated into clinical care for this vulnerable patient population.
