Background Insomnia treatment using an internet-based cognitive–behavioural therapy for insomnia (CBT-I) program reduces depression symptoms, anxiety symptoms and suicidal ideation. However, the speed, longevity and consistency of these effects are unknown. Aims To test the following: whether the efficacy of online CBT-I was sustained over 18 months; how rapidly the effects of CBT-I emerged; evidence for distinct trajectories of change in depressive symptoms; and predictors of these trajectories. Method A randomised controlled trial compared the 6-week Sleep Healthy Using the Internet (SHUTi) CBT-I program to an attention control program. Adults ( N =1149) with clinical insomnia and subclinical depression symptoms were recruited online from the Australian community. Results Depression, anxiety and insomnia decreased significantly by week 4 of the intervention period and remained significantly lower relative to control for >18 months (between-group Cohen’s d =0.63, 0.47, 0.55, respectively, at 18 months). Effects on suicidal ideation were only short term. Two depression trajectories were identified using growth mixture models: improving (95%) and stable/deteriorating (5%) symptoms. More severe baseline depression, younger age and limited comfort with the internet were associated with reduced odds of improvement. Conclusions Online CBT-I produced rapid and long-term symptom reduction in people with subclinical depressive symptoms, although the initial effect on suicidal ideation was not sustained.

BackgroundComputerised cognitive-behavioural therapy (CCBT) helps improve mental health outcomes in White populations. However, no studies have examined whether CCBT is acceptable and beneficial for African Americans.AimsWe studied differences in CCBT use and self-reported change in depression and anxiety symptoms among 91 African Americans and 499 White primary care patients aged 18–75, enrolled in a randomised clinical trial of collaborative care embedded with an online treatment for depression and anxiety.MethodPatients with moderate levels of mood and/or anxiety symptoms (PHQ-9 or GAD-7≥10) were randomised to receive either care-manager-guided access to the proven-effective Beating the Blues® CCBT programme or usual care from their primary care doctor.ResultsCompared with White participants, African Americans were less likely to start the CCBT programme (P=0.01), and those who did completed fewer sessions and were less likely to complete the full programme (P=0.03). Despite lower engagement, however, African Americans who started the CCBT programme experienced a greater decrease in self-reported depressive symptoms (estimated 8-session change: −6.6 v. −5.5; P=0.06) and similar decrease in anxiety symptoms (−5.3 v. −5.6; P=0.80) compared with White participants.ConclusionsCCBT may be an efficient and scalable first-step to improving minority mental health and reducing disparities in access to evidence-based healthcare.

BackgroundSymptoms of anxiety and depression are prevalent in older adults.AimsTo compare clinician-guided and self-guided versions of a transdiagnostic internet-delivered cognitive–behavioural therapy (iCBT) intervention for adults aged 60 years and above.MethodAdults (n=433) with symptoms of anxiety and depression were randomly allocated to: (1) clinician-guided treatment (n=153); (2) initial clinician interview followed by self-guided treatment (n=140); or (3) self-guided treatment without interview (n=140).ResultsLarge reductions (d ≥1.00) in symptoms of depression and anxiety were observed across groups, and sustained at follow-up. No differences were observed in clinical outcomes or satisfaction ratings. Age did not affect outcomes.ConclusionsCarefully developed iCBT interventions may significantly reduce symptoms of anxiety and depression in older adults when delivered in either clinician-guided or self-guided formats.

BackgroundDepression is a prevalent long-term condition that is associated with substantial resource use. Telehealth may offer a cost-effective means of supporting the management of people with depression.AimsTo investigate the cost-effectiveness of a telehealth intervention (‘Healthlines’) for patients with depression.MethodA prospective patient-level economic evaluation conducted alongside a randomised controlled trial. Patients were recruited through primary care, and the intervention was delivered via a telehealth service. Participants with a confirmed diagnosis of depression and PHQ-9 score ≥10 were recruited from 43 English general practices. A series of up to 10 scripted, theory-led, telephone encounters with health information advisers supported participants to effect a behaviour change, use online resources, optimise medication and improve adherence. The intervention was delivered alongside usual care and was designed to support rather than duplicate primary care. Cost-effectiveness from a combined health and social care perspective was measured by net monetary benefit at the end of 12 months of follow-up, calculated from incremental cost and incremental quality-adjusted life years (QALYs). Cost–consequence analysis included cost of lost productivity, participant out-of-pocket expenditure and the clinical outcome.ResultsA total of 609 participants were randomised – 307 to receive the Healthlines intervention plus usual care and 302 to receive usual care alone. Forty-five per cent of participants had missing quality of life data, 41% had missing cost data and 51% of participants had missing data on either cost or utility, or both. Multiple imputation was used for the base-case analysis. The intervention was associated with incremental mean per-patient National Health Service/personal social services cost of £168 (95% CI £43 to £294) and an incremental QALY gain of 0.001 (95% CI −0.023 to 0.026). The incremental cost-effectiveness ratio was £132 630. Net monetary benefit at a cost-effectiveness threshold of £20 000 was –£143 (95% CI –£164 to –£122) and the probability of the intervention being cost-effective at this threshold value was 0.30. Productivity costs were higher in the intervention arm, but out-of-pocket expenses were lower.ConclusionsThe Healthlines service was acceptable to patients as a means of condition management, and response to treatment after 4 months was higher for participants randomised to the intervention. However, the positive average intervention effect size was modest, and incremental costs were high relative to a small incremental QALY gain at 12 months. The intervention is not likely to be cost-effective in its current form.
