- OBJECTIVES: Few treatments have been able to effectively manage pediatric irritable bowel syndrome (IBS). Internet-delivered cognitive behavior therapy (Internet-CBT) based on exposure for abdominal symptoms is effective for adult IBS. The objective of this study was to evaluate the efficacy of Internet-CBT based on behavioral exposure for adolescents with IBS. METHODS: Adolescents with IBS fulfilling the Rome III criteria were randomized to either Internet-CBT or a wait-list control. The Internet-CBT was a 10-week intervention where the main component was exposure to IBS symptoms by reduction of avoidance of abdominal symptoms and instead stepwise provocation of symptoms. The primary outcome was total score on Gastrointestinal Symptoms Rating Scale for IBS (GSRS-IBS). Secondary outcomes included adolescent- and parent-rated quality of life and parent-rated gastrointestinal symptoms. Difference between groups was assessed from pretreatment to posttreatment and the Internet-CBT group was also evaluated at 6 months after treatment completion. RESULTS: A total of 101 adolescents with IBS (13-17 years of age) were included in this study. Dropout rates were low (6%) and all randomized patients were included in intent-to-treat analyses based on mixed effects models. Analyses showed a significant larger pretreatment to posttreatment change on the primary outcome GSRS-IBS (B=-6.42, P=0.006, effect size Cohen's d=0.45, 95% confidence interval (0.12, 0.77)) and on almost all secondary outcomes for the Internet-CBT group compared with the control group. After 6 months, the results were stable or significantly improved. CONCLUSIONS: Internet-CBT based on exposure exercises for adolescents with IBS can effectively improve gastrointestinal symptoms and quality of life.

- To assess whether exposure-based internet-delivered cognitive–behavioural therapy (internet-CBT) is a cost-effective treatment for adolescents with irritable bowel syndrome (IBS) compared with a waitlist control, from a societal perspective, based on data from a randomised trial.DesignWithin-trial cost-effectiveness analysis.SettingParticipants were recruited from the whole of Sweden via primary, secondary and tertiary care clinics reached through news media and advertising.ParticipantsAdolescents (aged 13–17) with a diagnosis of IBS.InterventionsParticipants were randomised to either an exposure-based internet-CBT, including 10 weekly modules for adolescents and five modules for parents, or a waitlist.Outcome measuresThe main health outcome was the quality-adjusted life-year (QALY) estimated by mapping Pediatric Quality-of-Life Inventory (PedsQL) scores onto EQ-5D-3L utilities. The secondary outcome was the point improvement on the PedsQL scale. Data on health outcomes and resource use were collected at baseline and 10 weeks post-treatment. Resource use was measured using the Trimbos and Institute of Medical Technology Assessment Cost Questionnaire for Psychiatry (TIC-P) . Incremental cost-effectiveness ratios (ICER) were calculated as the difference in average costs by the difference in average outcomes between groups.ResultsThe base-case results showed that internet-CBT costs were on average US$170.24 (95% CI 63.14 to 315.04) more per participant than the waitlist. Adolescents in the internet-CBT group showed small QALY gains (0.0031; 95% CI 0.0003 to 0.0061), and an average improvement of 5.647 points (95% CI 1.82 to 9.46) on the PedsQL compared with the waitlist. Internet-CBT yielded an ICER of $54 916/QALY gained and a probability of cost-effectiveness of 74% given the Swedish willingness-to-pay threshold. The ICER for the outcome PedsQL was US$85.29/point improvement.ConclusionsOffering internet-CBT to adolescents with IBS improves health-related quality of life and generates small QALY gains at a higher cost than a waitlist control. Internet-CBT is thus likely to be cost-effective given the strong efficacy evidence, small QALY gains and low cost.Trial registration numberNCT02306369; Results.
