Effects of Anger Awareness and Expression Training versus Relaxation Training on Headaches: A Randomized Trial

Background and purpose: Stress contributes to headaches, and effective interventions for headaches routinely include relaxation training (RT) to directly reduce negative emotions and arousal. Yet, suppressing negative emotions, particularly anger, appears to augment pain, and experimental studies suggest that expressing anger may reduce pain. Therefore, we developed and tested anger awareness and expression training (AAET) on people with headaches. Methods: Young adults with headaches (N = 147) were randomized to AAET, RT, or a wait-list control. We assessed affect during sessions, and process and outcome variables at baseline and 4 weeks after treatment. Results: On process measures, both interventions increased self-efficacy to manage headaches, but only AAET reduced alexithymia and increased emotional processing and assertiveness. Yet, both interventions were equally effective at improving headache outcomes relative to controls. Conclusions: Enhancing anger awareness and expression may improve chronic headaches, although not more than RT. Researchers should study which patients are most likely to benefit from an emotional expression or emotional reduction approach to chronic pain

Effect of brain-gut behavioral treatments on abdominal pain in irritable bowel syndrome: systematic review and network meta-analysis

Background and aims: some brain-gut behavioral treatments (BGBTs) are beneficial for global symptoms in irritable bowel syndrome (IBS). US management guidelines suggest their use in patients with persistent abdominal pain but their specific effect on this symptom has not been assessed systematically.Methods: we searched the literature through 16th December 2023 for randomized controlled trials (RCTs) assessing efficacy of BGBTs for adults with IBS, compared with each other, or a control intervention. Trials provided an assessment of abdominal pain resolution or improvement at treatment completion. We extracted data as intention-to-treat analyses, assuming dropouts to be treatment failures and reporting pooled relative risks (RRs) of abdominal pain not improving with 95% confidence intervals (CIs), ranking therapies according to P-score.Results: we identified 42 eligible RCTs, containing 5220 participants. After treatment completion, the BGBTs with the largest numbers of trials, and patients recruited, demonstrating efficacy for abdominal pain, specifically, included self-guided/minimal contact cognitive behavioral therapy (CBT) (RR = 0.71; 95% CI 0.54-0.95, P-score 0.58), face-to-face multicomponent behavioral therapy (RR = 0.72; 95% CI 0.54-0.97, P score 0.56), and face-to-face gut-directed hypnotherapy (RR = 0.77; 95% CI 0.61-0.96, P-score 0.49). Among trials recruiting only patients with refractory global IBS symptoms, group CBT was more efficacious than routine care for abdominal pain, but no other significant differences were detected. No trials were low risk of bias across all domains and there was evidence of funnel plot asymmetry.Conclusions: several BGBTs, including self-guided/minimal contact CBT, face-to-face multicomponent behavioral therapy, and face-to-face gut-directed hypnotherapy may be efficacious for abdominal pain in IBS, although none were superior to another

Efficacy of psychological therapies for irritable bowel syndrome: systematic review and network meta-analysis

Objectives National guidelines for the management of irritable bowel syndrome (IBS) recommend that psychological therapies should be considered, but their relative efficacy is unknown, because there have been few head-to-head trials. We performed a systematic review and network meta-analysis to try to resolve this uncertainty. Design We searched the medical literature through January 2020 for randomised controlled trials (RCTs) assessing efficacy of psychological therapies for adults with IBS, compared with each other, or a control intervention. Trials reported a dichotomous assessment of symptom status after completion of therapy. We pooled data using a random effects model. Efficacy was reported as a pooled relative risk (RR) of remaining symptomatic, with a 95% CI to summarise efficacy of each comparison tested, and ranked by therapy according to P score. Results We identified 41 eligible RCTs, containing 4072 participants. After completion of therapy, the psychological interventions with the largest numbers of trials, and patients recruited, demonstrating efficacy included self-administered or minimal contact cognitive behavioural therapy (CBT) (RR 0.61; 95% CI 0.45 to 0.83, P score 0.66), face-to-face CBT (RR 0.62; 95% CI 0.48 to 0.80, P score 0.65) and gut-directed hypnotherapy (RR 0.67; 95% CI 0.49 to 0.91, P score 0.57). After completion of therapy, among trials recruiting only patients with refractory symptoms, group CBT and gut-directed hypnotherapy were more efficacious than either education and/or support or routine care, and CBT via the telephone, contingency management, CBT via the internet and dynamic psychotherapy were all superior to routine care. Risk of bias of trials was high, with evidence of funnel plot asymmetry; the efficacy of psychological therapies is therefore likely to have been overestimated. Conclusions Several psychological therapies are efficacious for IBS, although none were superior to another. CBT-based interventions and gut-directed hypnotherapy had the largest evidence base and were the most efficacious long term. Trial registration number The study protocol was published on the PROSPERO international prospective register of systematic reviews (registration number CRD 42020163246)
