- Objectives: This study tested the acceptability and efficacy of an Acceptance and Commitment Therapy and compassion-based intervention (LIFEwithIBD) in people with IBD through a two-arm RCT.Methods: Participants were recruited at the Gastroenterology Department of the Coimbra University Hospital between June and September 2019. Of the 355 patients screened, those who accepted to participate were randomly assigned to one of two conditions: experimental group (LIFEwithIBD; n = 25) or control group (waitlist; n = 29). Participants completed self-report measures at baseline (T0), post-intervention (T1), and 3-month (T2) and 12-month (T3) follow-ups. Intervention acceptability was assessed. Efficacy was examined using intent-to-treat ANCOVA at post-intervention after adjusting for baseline values of depressive, anxiety, and stress symptoms (primary outcomes). Linear mixed models for all longitudinal outcomes were also analysed. Inflammatory and disease biomarkers were determined at T0 and T3.Results: Acceptability results revealed a high level of satisfaction and perceived usefulness regarding the intervention. Both groups experienced a significant decrease in stress symptoms and IBD symptom perception at T1. No significant differences were observed at follow-up for the primary outcomes. The experimental group reported significantly lower Crohn’s disease Symptom severity at T2 than the control group. Post-hoc analyses designed to mitigate floor effects revealed substantial treatment effects for the experimental group regarding anxiety symptoms. No significant differences were observed in clinical biomarkers from T0 to T3.Conclusion: The LIFEwithIBD intervention shows promising, although preliminary, benefits for managing disease activity and reducing anxiety symptoms in IBD patients with high severity of psychological distress.

- Research has questioned whether it is feasible to assess psychosocial variables through web-based recruitment methods. Previous literature on IBD focused exclusively on testing differences on psychosocial scores and did not test the invariance between types of recruitment on the relationships between variables. The aim of the present study is thus to analyse structural invariance between internet-recruited and hospital-recruited groups of IBD patients on a mediation model with theoretical basis on previous studies (experiential avoidance as possible mediator of the association between IBD symptomatology and psychopathology). The internet sample included 137 IBD patients recruited through a patients association, and the hospital sample comprised 66 IBD patients. Structural equation modelling was used; a multiple-group comparison was conducted to examine model invariance between samples. Although the internet sample presented higher levels of experiential avoidance and psychopathological symptoms compared to the hospital sample, the relationships between these variables were invariant across groups. Experiential avoidance partially mediated the impact of IBD symptomatology on levels of stress, anxiety, and depression symptoms in a similar way for online respondents and hospital-recruited patients. This is a new finding that argues for the validity of web-based research methods.

- Considering that self-criticism is an important process in the development and maintenance of depression, and taking into account the stigma associated with inflammatory bowel disease (IBD), the present study aimed to analyse whether self-criticism exacerbates the relationships of depression symptoms with IBD symptomatology and chronic illness-related shame. The sample included 53 ambulatory IBD patients (66% females) with ages from 18 to 65. Moderation analyses were conducted using structural equation modelling. Self-criticism exacerbated the associations of depression with IBD symptoms (b = 0.01; standard error [SE] = 0.00; Z = 3.73; P < .001) and illness shame (b = 0.02; SE = 0.01; Z = 2.40; P = .016). For the same level of IBD symptomatology or chronic illness-related shame, those individuals who present more feelings of inadequacy towards the self, experience more symptoms of depression. This exacerbation effect is stronger when IBD symptomatology and chronic illness-related shame are more intense. A high self-critical IBD patient may view the illness and/or symptomatology as a flaw or error that should be self-corrected. Physicians and other health professionals should be attentive to these pathological mechanisms and should attempt to alleviate them. It may be beneficial to refer high self-critical patients to psychological care.
