Internet-delivered cognitive behavioural therapy for adults with mild to moderate depression and high cardiovascular disease risks: a randomised attention-controlled trial.

ABSTRACT:

Background and aim

Mild to moderate depression is common in those with cardiovascular disease and undertreated. We aimed to evaluate the effectiveness of internet-delivered Cognitive Behaviour Therapy (iCBT) on depressive symptom severity and adherence to medical advice and lifestyle interventions in adults with mild to moderate depression and high cardiovascular disease (CVD) risks.

Methods

Randomised double-blind, 12 week attention-controlled trial comparing an iCBT programme (E-couch) with an internet-delivered attention control health information package (HealthWatch, n = 282). The primary outcome was depression symptom level on the nine-item Patient Health Questionnaire (PHQ-9) (trial registration: ACTRN12610000085077).

Results

487/562 (88%) participants completed the endpoint assessment. 383/562 (70%) were currently treated for cardiovascular disease and 314/562 (56%) had at least one other comorbid condition. In ITT analysis of 562 participants iCBT produced a greater decline in the mean PHQ-9 score compared to the attention control of 1.06 (95% CI: 0.23-1.89) points, with differences between the two arms increasing over the intervention period (time by treatment effect interaction p = .012). There were also larger improvements in adherence (2.16 points; 95% CI: 0.33-3.99), reductions in anxiety (0.96 points; 95% CI: 0.19-1.73), and a greater proportion engaging in beneficial physical activity (Odds Ratio 1.91, 95%CI: 1.01-3.61) in the iCBT participants but no effect upon disability, or walking time/day. There were no withdrawals due to study related adverse events.

Conclusions

In people with mild to moderate depression and high levels of CVD risk factors, a freely accessible iCBT programme (http://www.ecouch.anu.edu.au) produced a small, but robust, improvement in depressive symptoms, adherence and some health behaviours.

Project description:Depression is the principal cause of disability in the world. High prevalence rates of depression in general populations and college students have been found worldwide and in various cultural groups. Low-intensity cognitive behavioural internet-delivered treatment has demonstrated efficacy in high-income-countries (HICs). However little is known of their potential for adaptation and efficacy in low and middle-income countries.Study (1) involves the cultural adaptation of the Space from Depression cognitive-behaviour internet-delivered programme with an asynchronous support for depressive symptoms. This includes initial researcher/clinician adaptation and the integration of cultural assessment feedback of the programme by a panel of experts and users through the theoretically-based Cultural Relevance Questionnaire (CRQ). Study (2) describes the implementation of the culturally adapted intervention using a randomised controlled trial methodology. The efficacy trial will include an active treatment group and a waiting-list control group of participants meeting eligibility criteria (mild to moderate depression symptoms). The active condition will consist of 7 weekly modules of internet-delivered cognitive behavioural therapy (iCBT) Space from Depression, with post-session feedback support. The primary outcome will be the Patient Health Questionnaire (PHQ-9). The study also involves collection of client reported significant events and client satisfaction with the internet-delivered treatment. Data will be collected at baseline and at post-treatment (week 7), and at follow-up (week 20/3 months). Analysis will be conducted on the intention-to-treat basis.The study seeks to establish a theoretically robust methodology for culturally adapting internet-delivered interventions for mental health disorders and to evaluate the efficacy of a culturally adapted internet-delivered treatment for depression in Colombia, with support. The study will be a first contribution to a method for culturally adapting internet-delivered interventions and also a first to examine the efficacy of such an adapted intervention in Latin America.Clinical trials NCT03062215.

Project description:BackgroundThe COVID-19 pandemic has had major impacts in many different spheres, including mental health. Children and adolescents are especially vulnerable because their central nervous system is still in development and they have fewer coping resources than do adults. Increases in the prevalence of depressive and anxiety symptomatology have been reported worldwide. However, access to mental health care is limited, especially for the paediatric population and in low- and middle-income countries. Therefore, we developed a brief internet-delivered cognitive-behavioural intervention for children and adolescents with symptoms of anxiety and depression. The aim of this proposed study is to test the efficacy of the intervention.MethodsWe will conduct a two-arm, parallel randomised controlled trial involving children and adolescents (8-11 and 12-17 years of age, respectively) with symptoms of anxiety, depression or both, according to the 25-item Revised Child Anxiety and Depression Scale (t-score > 70). A total of 280 participants will be randomised to the intervention group or the active control group, in a 1:1 ratio. Those in the intervention group will receive five weekly sessions of cognitive-behavioural therapy via teleconference. The sessions will focus on stress responses, family communication, diaphragmatic breathing, emotions, anger management, behavioural activation and cognitive restructuring. Participants in both groups will have access to 15 videos covering the same topics. Participant-guardian pairs will be expected to attend the sessions (intervention group), watch the videos (control group) or both (intervention group only). A blinded assessor will collect data on symptoms of anxiety, depression and irritability, at baseline, at the end of the intervention and 30 days thereafter. Adolescents with access to a smartphone will also be invited to participate in an ecological momentary assessment of emotional problems in the week before and the week after the intervention, as well as in passive data collection from existing smartphone sensors throughout the study.DiscussionInternet-delivered interventions play a major role in increasing access to mental health care. A brief, manualised, internet-delivered intervention might help children and adolescents with anxiety or depressive symptomatology, even outside the context of the COVID-19 pandemic.Trial registrationClinicalTrials.gov NCT05139433.

Project description:OBJECTIVE: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. DESIGN:Within-trial cost-effectiveness analysis. SETTING:Participants were recruited from the whole of Sweden via primary, secondary and tertiary care clinics reached through news media and advertising. PARTICIPANTS:Adolescents (aged 13-17) with a diagnosis of IBS. INTERVENTIONS:Participants were randomised to either an exposure-based internet-CBT, including 10 weekly modules for adolescents and five modules for parents, or a waitlist. OUTCOME MEASURES:The 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. RESULTS:The 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. CONCLUSIONS:Offering 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 NUMBER:NCT02306369; Results.
