Long-term outcomes of internet-delivered cognitive behaviour therapy for paediatric anxiety disorders: towards a stepped care model of health care delivery.

ABSTRACT: Internet-delivered cognitive behaviour therapy (ICBT) is emerging as a powerful tool to fill the gap between demand and availability of evidence-based treatment for paediatric anxiety disorders. However, it is still unclear how to best implement it in routine clinical care. 123 children (8-12 years) with anxiety disorders underwent a 12-week ICBT programme with limited therapist support. Participants were assessed 3- and 12-month post-ICBT (3MFU and 12MFU, respectively). Non-remitters who still fulfilled diagnostic criteria for their principal anxiety disorder at 3MFU were offered additional manualised "face-to-face" (F2F) CBT. The aim of the study was to emulate a stepped-care model of health care delivery, where the long-term treatment gains of ICBT as well as the potential benefit of proving addition treatment to non-remitters of ICBT were evaluated. Remitters of ICBT (n = 73) continued to improve throughout the study period (pre-ICBT to 12MFU; Cohen's d = 2.42). At 12MFU, 89% (n = 65) were free from their principal anxiety disorder. Of all the participants classed as non-remitters at 3MFU (n = 37), 48.6% (n = 18) accepted the offer to receive additional F2F CBT. These participants also improved with a large effect from pre-ICBT to 12MFU (Cohen's d = 2.27), with the largest effect occurring during F2F CBT. At 12MFU, 83% (n = 15) were free from their principal anxiety disorders. The majority of non-remitters declining additional F2F CBT (63.2%; n = 12) did so due to already receiving treatment at their local CAMHS, prior to 3MFU. The effects of ICBT for anxiety disorders are durable at least up to 1 year after the end of treatment. Patients who fail to fully benefit from ICBT improved further with additional F2F sessions at our clinic, suggesting that it may be feasible to implement ICBT within a stepped-care model of health care delivery.

Project description:BackgroundCollaborative care for depression is more effective in improving treatment outcomes than primary care physicians' (PCPs) usual care (UC). However, few trials of collaborative care have targeted anxiety.ObjectiveTo examine the impact and 12-month durability of a centralized, telephone-delivered, stepped collaborative care intervention (CC) for treating anxiety disorders across a network of primary care practices.DesignRandomized controlled trial with blinded outcome assessments.ParticipantsA total of 329 patients aged 18-64 referred by their PCPs in response to an electronic medical record (EMR) prompt. They include 250 highly anxious patients randomized to either CC or to UC, and 79 moderately anxious patients who were triaged to a watchful waiting (WW) cohort and later randomized if their conditions clinically deteriorated.InterventionTwelve months of telephone-delivered CC involving non-mental health professionals who provided patients with basic psycho-education, assessed preferences for guideline-based pharmacotherapy, monitored treatment responses, and informed PCPs of their patients' care preferences and progress via the EMR.Main measuresMental health-related quality of life ([HRQoL]; SF-36 MCS); secondary outcomes: anxiety (Hamilton Anxiety Rating Scale [SIGH-A], Panic Disorder Severity Scale) and mood (PHQ-9).Key resultsAt 12-month follow-up, highly anxious patients randomized to CC reported improved mental HRQoL (effect size [ES]: 0.38 [95 % CI: 0.13-0.63]; P = 0.003), anxiety (SIGH-A ES: 0.30 [0.05-0.55]; P = 0.02), and mood (ES: 0.45 [0.19-0.71] P = 0.001) versus UC. These improvements were sustained for 12 months among African-Americans (ES: 0.70-1.14) and men (ES: 0.43-0.93). Of the 79 WW patients, 29 % met severity criteria for randomization, and regardless of treatment assignment, WW patients reported fewer anxiety and mood symptoms and better mental HRQoL over the full 24-month follow-up period than highly anxious patients who were randomized at baseline.ConclusionsTelephone-delivered, centralized, stepped CC improves mental HRQoL, anxiety and mood symptoms. These improvements were durable and particularly evident among those most anxious at baseline, and among African-Americans and men.

Project description:Few studies have evaluated the implementation of ICBT in regular child and adolescent mental health services (CAMHS). This study aimed to explore the acceptability, feasibility, and effectiveness of ICBT for children and adolescents with anxiety disorders and obsessive-compulsive disorder (OCD) within a rural CAMHS. The study also explored outcome predictors and long-term outcomes. Eighty-three participants were consecutively recruited from a non-specialized CAMHS in Region Jämtland Härjedalen in northern Sweden. Therapist-guided ICBT was offered during 12 weeks to children aged 8-17 with an anxiety disorder or OCD. Acceptability and feasibility measures included treatment adherence, treatment satisfaction, and adverse events. The primary outcome measure was the Clinical Global Impression-Severity. Secondary measures of effectiveness included clinician-, self-, and parent-ratings of symptom severity and functional impairment. Assessments were completed at baseline, post-treatment, and three-month follow-up (primary endpoint). A two-year follow up was conducted using medical records. Potential predictors included both patient characteristics and treatment variables. Results indicated that ICBT was both acceptable and feasible according to study measures. Statistically significant improvements were found from baseline to the three-month follow-up on clinician rated severity (B [SE] = -0.92 [0.09]; p < .001), as well as on all secondary measures. Forty-three percent of participants no longer fulfilled criteria for their principal disorder at the three-month follow-up. No serious adverse events were reported. Clinical improvement was highest among children with higher functioning at baseline (B [SE] = -0.05 [0.02]; p < .05). Forty-six percent of participants had been in contact with CAMHS during the two-year follow-up period, mainly for reasons other than their initial diagnosis. Findings suggest that ICBT could be an acceptable and feasible treatment option for young people with anxiety disorders and OCD in rural non-specialized CAMHS settings. Further studies are needed to confirm treatment effectiveness in this setting. Trial registration: NCT02926365.

Project description:BackgroundAmple studies have shown the effectiveness of internet-delivered cognitive behavioral therapy (iCBT) for anxiety disorders. These studies recruited their participants mainly from the community and, to a lesser extent, from within routine care services. Little is known about whether different recruitment strategies lead to different treatment effects.ObjectiveThis meta-analysis compared clinical results obtained in trials with recruitment from the community versus results obtained in trials with clinical service recruitment and explored factors that may mediate differences in treatment outcome.MethodsWe included randomized controlled trials in which the clinical effects of iCBT for anxiety disorders were compared with a control condition (waitlist controls or face-to-face cognitive behavioral therapy). We classified trials as open recruitment trials (recruitment from the community) or clinical service recruitment trials (recruitment through outpatient clinics). Pooled effect sizes based on measures examining anxiety symptoms, depressive symptoms, and quality of life were computed for each type of trial. Subgroup analyses examined whether clinical results from open recruitment trials differed from those obtained in clinical service recruitment trials. Additional analyses explored which demographic, clinical, and treatment-related factors contributed to differences in effect sizes of open recruitment versus clinical service recruitment trials.ResultsWe included 42 studies with 53 comparisons (43 open recruitment comparisons and 10 clinical recruitment comparisons). Analyses of anxiety measures revealed, first, that iCBT open recruitment studies with waitlist control comparators showed a significantly higher effect size for decrease in anxiety symptoms than did those with clinical recruitment (Q=10.09; P=.001). This association between recruitment method and effect size was no longer significant in a multivariate metaregression with treatment adherence and exclusion of patients with depressive symptoms entered as additional predictors of effect size. Second, effect size for decrease in anxiety symptoms did not differ significantly between clinical recruitment and open recruitment studies with face-to-face cognitive behavioral therapy comparators. The effects of open recruitment trials and clinical recruitment trials did not differ significantly for the secondary outcomes, compared with face-to-face cognitive behavioral therapy and waitlist controls.ConclusionsiCBT was effective in samples recruited in clinical practice, but effect sizes were smaller than those found in trials with an open recruitment method for studies with waitlist control comparators. Hence, for patients with anxiety disorders in routine care, the impact of iCBT may not be as positive as for study participants recruited from the community. The difference between open recruitment trials and clinical service recruitment trials might be partly explained by patients' greater therapy adherence in open recruitment trials and the stricter exclusion of patients with severe depressive symptoms in these studies. Since most trials in this meta-analysis applied an open recruitment method, more studies with routine care populations are needed to further validate these findings.

Project description:OBJECTIVES:To evaluate the cost-effectiveness of a therapist-guided internet-delivered cognitive behaviour therapy (ICBT) intervention for adolescents with obsessive-compulsive disorder (OCD) compared with untreated patients on a waitlist. DESIGN:Single-blinded randomised controlled trial. SETTING:A research clinic within the regular child and adolescent mental health service in Stockholm, Sweden. PARTICIPANTS:Sixty-seven adolescents (12-17?years) with a Diagnostic and Statistical Manual of Mental Disorders Fifth Edition diagnosis of OCD. INTERVENTIONS:Either a 12-week, therapist-guided ICBT intervention or a wait list condition of equal duration. PRIMARY OUTCOME MEASURES:Cost data were collected at baseline and after treatment, including healthcare use, supportive resources, prescription drugs, prescription-free drugs, school absence and productivity loss, as well as the cost of ICBT. Health outcomes were defined as treatment responder rate and quality-adjusted life years gain. Bootstrapped mixed model analyses were conducted comparing incremental costs and health outcomes between the groups from the societal and healthcare perspectives. RESULTS:Compared with waitlist control, ICBT generated substantial societal cost savings averaging US$-144.98 (95%?CI -159.79 to -130.16) per patient. The cost reductions were mainly driven by reduced healthcare use in the ICBT group. From the societal perspective, the probability of ICBT being cost saving compared with waitlist control was approximately 60%. From the healthcare perspective, the cost per additional responder to ICBT compared with waitlist control was approximately US$78. CONCLUSIONS:The results suggest that therapist-guided ICBT is a cost-effective treatment and results in societal cost savings, compared with patients who do not receive evidence-based treatment. Since, at present, most patients with OCD do not have access to evidence-based treatments, the results have important implications for the increasingly strained national and healthcare budgets. Future studies should compare the cost-effectiveness of ICBT with regular face-to-face CBT. TRIAL REGISTRATION NUMBER:NCT02191631.
