Effect of Internet-based Cognitive Behavioral Humanistic and Interpersonal Training vs. Internet-based General Health Education on Adolescent Depression in Primary Care: A Randomized Clinical Trial.

ABSTRACT:

Importance

Although 13-20% of American adolescents experience a depressive episode annually, no scalable primary care model for adolescent depression prevention is currently available.

Objective

To study whether CATCH-IT (Competent Adulthood Transition with Cognitive Behavioral Humanistic and Interpersonal Training) reduces the hazard for depression in at-risk adolescents identified in primary care, as compared to a general health education attention control (HE).

Design

The Promoting AdolescenT Health (PATH) study compares CATCH-IT and HE in a phase 3 single-blind multicenter randomized attention control trial. Participants were enrolled from 2012 to 2016 and assessed at 2, 6, 12, 18, and 24 months post-randomization.

Setting

Primary care.

Participants

Eligible adolescents were 13-18 years with subsyndromal depression and/or history of depression and no current depression diagnosis or treatment. Of 2,250 adolescents screened for eligibility, 446 participants completed the baseline interview and 369 were randomized into CATCH-IT (n=193) and HE (n=176).

Interventions

CATCH-IT is a 20-module (15 adolescent modules, 5 parent modules) online psychoeducation course that includes a parent program, supported by three motivational interviews.

Main outcomes and measures

Time-to-event for depressive episode; depressive symptoms at 6 months.

Results

Mean age was 15.4 years, and 68% were female; 28% had both a past episode and subsyndromal depression; 12% had a past episode only, 59% had subsyndromal depression only, and 1% had borderline subsyndromal depression. The outcome of time-to-event favored CATCH-IT but was not significant with intention-to-treat analyses (N=369; unadjusted HR=0.59; 95% CI 0.27, 1.29; p=0.18; adjusted HR=0.53; 95% CI 0.23, 1.23, p=0.14). Adolescents with higher baseline CES-D₁₀ scores showed a significantly stronger effect of CATCH-IT on time-to-event relative to those with lower baseline scores (p=0.04). For example, for a CES-D₁₀ score of 15 (significant sub-syndromal depression), HR=0.20 (95% CI 0.05, 0.77), compared to CES-D₁₀ of 5 (no sub-syndromal depression), HR=1.44 (95% CI, 0.41, 5.03). In both CATCH-IT and HE groups, depression symptoms declined and functional scores increased.

Conclusions and relevance

CATCH-IT may be better than HE for preventing depressive episodes for at-risk adolescents with sub-syndromal depression. CATCH-IT may be a scalable approach to prevent depressive episodes in adolescents in primary care.

Project description:ImportanceCognitive behavioral therapy (CBT) for obsessive-compulsive disorder (OCD) is a highly specialized treatment that is in short supply worldwide.ObjectivesTo investigate whether both therapist-guided and unguided internet-based CBT (ICBT) are noninferior to face-to-face CBT for adults with OCD, to conduct a health economic evaluation, and to determine whether treatment effects were moderated by source of participant referral.Design, setting, and participantsThis study is a single-blinded, noninferiority, randomized clinical trial, with a full health economic evaluation, conducted between September 2015 and January 2020, comparing therapist-guided ICBT, unguided ICBT, and individual face-to-face CBT for adults with OCD. Follow-up data were collected up to 12 months after treatment. The study was conducted at 2 specialist outpatient OCD clinics in Stockholm, Sweden. Participants included a consecutive sample of adults with a primary diagnosis of OCD, either self-referred or referred by a clinician. Data analysis was performed from June 2019 to January 2022.InterventionsGuided ICBT, unguided ICBT, and face-to-face CBT delivered over 14 weeks.Main outcomes and measuresThe primary end point was the change in OCD symptom severity from baseline to 3-month follow-up. The noninferiority margin was 3 points on the masked assessor-rated Yale-Brown Obsessive Compulsive Scale.ResultsA total of 120 participants were enrolled (80 women [67%]; mean [SD] age, 32.24 [9.64] years); 38 were randomized to the face-to-face CBT group, 42 were randomized to the guided ICBT group, and 40 were randomized to the unguided ICBT group. The mean difference between therapist-guided ICBT and face-to-face CBT at the primary end point was 2.10 points on the Yale-Brown Obsessive Compulsive Scale (90% CI, -0.41 to 4.61 points; P = .17), favoring face-to-face CBT, meaning that the primary noninferiority results were inconclusive. The difference between unguided ICBT and face-to-face CBT was 5.35 points (90% CI, 2.76 to 7.94 points; P < .001), favoring face-to-face CBT. The health economic analysis showed that both guided and unguided ICBT were cost-effective compared with face-to-face CBT. Source of referral did not moderate treatment outcome. The most common adverse events were anxiety (30 participants [25%]), depressive symptoms (20 participants [17%]), and stress (11 participants [9%]).Conclusions and relevanceThe findings of this randomized clinical trial of ICBT vs face-to-face CBT for adults with OCD do not conclusively demonstrate noninferiority. Therapist-guided ICBT could be a cost-effective alternative to in-clinic CBT for adults with OCD in scenarios where traditional CBT is not readily available; unguided ICBT is probably less efficacious but could be an alternative when providing remote clinician support is not feasible.Trial registrationClinicalTrials.gov Identifier: NCT02541968.

Project description:BackgroundPhysical activity improves pain and function among individuals with knee osteoarthritis (OA), but most people with this condition are inactive. Physical therapists play a key role in helping people with knee OA to increase appropriate physical activity. However, health care access issues, financial constraints, and other factors impede some patients from receiving physical therapy (PT) for knee OA. A need exists to develop and evaluate other methods to provide physical activity instruction and support to people with knee OA. This study is examining the effectiveness of an internet-based exercise training (IBET) program designed for knee OA, designed by physical therapists and other clinicians.Methods/designThis is a randomized controlled trial of 350 participants with symptomatic knee OA, allocated to three groups: IBET, standard PT, and a wait list (WL) control group (in a 2:2:1 ratio, respectively). The study was funded by the Patient Centered Outcomes Research Institute, which conducted a peer review of the proposal. The IBET program provides patients with a tailored exercise program (based on functional level, symptoms, and current activity), video demonstrations of exercises, and guidance for appropriate exercise progression. The PT group receives up to 8 individual visits with a physical therapist, mirroring standard practice for knee OA and with an emphasis on a home exercise program. Outcomes are assessed at baseline, 4 months (primary time point) and 12 months (to assess maintenance of treatment effects). The primary outcome is the Western Ontario and McMaster Universities Osteoarthritis Index, and secondary outcomes include objective physical function, satisfaction with physical function, physical activity, depressive symptoms and global assessment of change. Linear mixed models will be used to compare both the IBET and standard PT groups to the WL control group, examine whether IBET is non-inferior to PT (a treatment that has an established evidence base for knee OA), and explore whether participant characteristics are associated with differential effects of IBET and/or standard PT. This research is in compliance with the Helsinki Declaration and was approved by the Institutional Review Board of the University of North Carolina at Chapel Hill.DiscussionThe IBET program could be disseminated widely at relatively low cost and could be an important resource for helping patients with knee OA to adopt and maintain appropriate physical activity. This trial will provide an important evaluation of the effectiveness of this IBET program for knee OA.Trial registrationNCT02312713.

Project description:ImportanceAccessible clinical care is not always available to individuals with distressing tinnitus. Internet-based cognitive behavioral therapy has the potential to increase access to evidence-based services that manage tinnitus. Research comparing the effectiveness of this internet-based intervention with face-to-face care is required.ObjectiveTo evaluate whether an internet-based cognitive behavioral therapy intervention is at least as effective as established individualized face-to-face clinical care in reducing tinnitus distress and tinnitus-related difficulties.Design, setting, and participantsA randomized, multicenter, 2-arm parallel group, noninferiority trial with 2-month follow-up was performed between October 4, 2016, and July 14, 2017. Invited to participate were 374 adults based in the United Kingdom who had been referred to their local tinnitus clinics because of bothersome tinnitus. The experimental group received the internet-based intervention online, and the active control group underwent the usual face-to-face tinnitus care at 1 of 3 UK-based National Health Service hospitals. Participants were randomly assigned (1:1) to either intervention using variable permuted block sizes of 4 and 6. Of 92 participants who were randomized (46 each in the experimental and control groups), 88 participants completed the assessment immediately after intervention and 74 participants completed the follow-up assessment.InterventionsParticipants were randomized to receive either 8 weeks of guided internet-based cognitive behavioral therapy or a mean of 2 to 3 individualized face-to-face appointments in a tinnitus clinic.Main outcomes and measuresThe primary outcome was a change in tinnitus distress (assessed by the Tinnitus Functional Index). Secondary assessment measures were included for insomnia, anxiety, depression, hearing disability, hyperacusis, cognitive failures, and satisfaction with life.ResultsOf 92 patients overall, 55 (60%) were men with a mean (SD) age of 52.96 (12.07) years and mean (SD) tinnitus duration of 6.54 (9.25) years. The between-group difference in the Tinnitus Functional Index scores after intervention were 5.18 (95% CI, -4.17 to 14.53) at the initial assessment and 5.52 (95% CI, -4.60 to 15.61) at follow-up; both differences were within the noninferiority margin of 13 points for the lower 95% CI. For the secondary outcomes, only outcomes for insomnia fell outside the noninferiority margin, both after intervention and at follow-up, favoring internet-based cognitive behavioral therapy.Conclusions and relevanceThis is the first trial, to our knowledge, to compare an internet-based intervention with standard individualized face-to-face care for tinnitus. It revealed that both interventions are equally effective for reducing tinnitus distress and most tinnitus-related difficulties.Trial registrationClinicalTrials.gov identifier: NCT02665975.
