- Social anxiety disorder (SAD) can be effectively treated with internet-delivered cognitive behavioural therapy (ICBT), but studies on long-term cost minimisation from a healthcare provider perspective in comparison to an evidence-based control treatment of therapeutic equivalence are lacking. The objective of the study was to determine whether ICBT reduces healthcare costs and use of healthcare resources compared with cognitive behavioural group therapy (CBGT).DesignA cost-minimisation study alongside a randomised controlled trial where participants (n=126) with SAD were randomised to ICBT or to CBGT. Costs measured from a healthcare provider perspective were estimated using time-driven activity-based costing alongside health status over 4 years from baseline measured with EQ-5D.SettingA psychiatric outpatient clinic in Stockholm, Sweden.ParticipantsParticipants were 126 individuals with SAD.Primary outcome measuresChanges in EQ-5D and costs.InterventionsParticipants received either CBGT or ICBT for a duration of 15 weeks.ResultsICBT minimised healthcare costs and demonstrated health improvements within the non-inferiority margin. Assuming a practical work capacity for personnel varying between 100%, 80% and 50% of theoretical full capacity, the cost for ICBT varied in the range between 400€, 463€ and 654 €, while the cost for CBGT varied between 699€, 806€ and 1134€. Within-group effect size was −0.36 (95% CI −0.70 to −0.01) for ICBT and −0.25 (95% CI −0.60 to 0.10) for CBGT. Mean use of effective psychologist time in ICBT was 189.60 (SD=53.77) minutes compared with 499.78 (SD=30.91) in the CBGT group.ConclusionsIn treatment of SAD, ICBT is equally effective but is associated with more efficient staff utilisation and less costs compared with CBGT. From a healthcare provider perspective, ICBT is an advantageous treatment option.Trial registration number

- Objective: Systematic exposure is potentially an effective treatment procedure for treating irritable bowel syndrome (IBS), but little is known about the processes by which it achieves its effect on outcome. The aim of this study was to identify mediators in a previously published randomized dismantling trial in which participants with IBS were randomized to Internet-delivered cognitive-behavioral treatment (ICBT) that incorporated systematic exposure or to the same treatment protocol without exposure (ICBT-WE). Method: Weekly measurements of gastrointestinal anxiety-specific process variables (behavioral avoidance, gastrointestinal-specific anxiety) based on the gastrointestinal symptom-specific anxiety model, generic process variables (self-efficacy and mindful nonreactivity), and treatment outcome (IBS symptoms) were obtained from 309 participants with IBS. Growth models and cross-lagged panel models, estimated within structural equation modeling, were employed to evaluate mediators of outcome. Results: Parallel process growth modeling showed that behavioral avoidance, gastrointestinal-specific anxiety, self-efficacy mediated the incremental effect of ICBT compared to ICBT-WE. The mediated effect of avoidance was stronger for individuals scoring high on the avoidance variable at 1st measurement point. Cross-lagged regression analyses with random effects revealed that behavioral avoidance and gastrointestinal-specific anxiety had a stronger effect on subsequent symptom change rather than vice versa, whereas mindful nonreactivity and self-efficacy displayed the opposite pattern. Conclusions: The evidence collectively provided support for the hypothesis that exposure for IBS achieves its positive results by virtue of changing gastrointestinal anxiety-specific processes rather than generic processes. IBS-specific behavioral avoidance emerged as the most clear-cut mediator of the specific effect of exposure on outcome.

- BACKGROUND & AIMS: Scalable and effective treatments are needed for children with functional abdominal pain disorders (FAPDs). We performed a randomized controlled trial of the efficacy and cost effectiveness of cognitive behavioral therapy delivered online (Internet-CBT) compared with usual therapy. METHODS: We studied children (age, 8-12 y) diagnosed with FAPDs, based on the Rome IV criteria, in Sweden from September 2016 through April 2017. The patients were assigned randomly to groups that received 10 weeks of therapist-guided, internet-delivered cognitive behavioral therapy (Internet-CBT, n = 46) or treatment as usual (treatments within the health care and school systems, including medications and visits to doctors and other health care professionals; n = 44). The primary outcome was global child-rated gastrointestinal symptom severity assessed using the Pediatric Quality of Life Gastrointestinal Symptom scale. All outcomes were collected from September 2016 through January 2018. Secondary outcomes included quality of life, gastrointestinal-specific anxiety, avoidance behaviors, and parental responses to children's symptoms. Societal costs and costs for health care consumption were collected during the treatment. RESULTS: Children who received Internet-CBT had a significantly larger improvement in gastrointestinal symptom severity with a medium effect size (Cohen's d = 0.46; 95% CI, 0.05-0.88; number needed to treat, 3.8) compared with children who received the treatment as usual. The children's quality of life, gastrointestinal-specific anxiety, avoidance behaviors, and parental responses to children's symptoms also improved significantly in the Internet-CBT group compared with the treatment as usual group. The effects of Internet-CBT persisted through 36 weeks of follow-up evaluation. Children who received Internet-CBT had significantly less health care use than children who received treatment as usual, with an average cost difference of US $137 (P = .011). We calculated a cost savings of US $1050 for every child treated with Internet-CBT compared with treatment as usual. CONCLUSIONS: In a randomized trial of pediatric patients with FAPDs, we found Internet-CBT to be clinically cost effective compared with treatment as usual. Internet-CBThas the potential to increase the availability of treatment for a number of patients and reduce health care costs.
