Demographic and clinical predictors of response to internet-enabled cognitive-behavioural therapy for depression and anxiety.

ABSTRACT: Background:Common mental health problems affect a quarter of the population. Online cognitive-behavioural therapy (CBT) is increasingly used, but the factors modulating response to this treatment modality remain unclear. Aims:This study aims to explore the demographic and clinical predictors of response to one-to-one CBT delivered via the internet. Method:Real-world clinical outcomes data were collected from 2211 NHS England patients completing a course of CBT delivered by a trained clinician via the internet. Logistic regression analyses were performed using patient and service variables to identify significant predictors of response to treatment. Results:Multiple patient variables were significantly associated with positive response to treatment including older age, absence of long-term physical comorbidities and lower symptom severity at start of treatment. Service variables associated with positive response to treatment included shorter waiting times for initial assessment and longer treatment durations in terms of the number of sessions. Conclusions:Knowledge of which patient and service variables are associated with good clinical outcomes can be used to develop personalised treatment programmes, as part of a quality improvement cycle aiming to drive up standards in mental healthcare. This study exemplifies translational research put into practice and deployed at scale in the National Health Service, demonstrating the value of technology-enabled treatment delivery not only in facilitating access to care, but in enabling accelerated data capture for clinical research purposes.

Project description:ObjectivesThe current study examined predictors of outcomes of internet-based cognitive-behavioural therapy (ICBT) for individuals with tinnitus.DesignSecondary analysis of intervention studies.SettingInternet-based guided tinnitus intervention provided in the UK.Participants228 individuals who underwent ICBT.InterventionsICBT.Primary and secondary outcome measuresThe key predictor variables included demographic, tinnitus, hearing-related and treatment-related variables as well as clinical factors (eg, anxiety, depression, insomnia), which can have an impact on the treatment outcome. A 13-point reduction in Tinnitus Functional Index (TFI) scores has been defined as a successful outcome.ResultsOf the 228 subjects who were included in the study, 65% had a successful ICBT outcome. As per the univariate analysis, participants with a master's degree or above had the highest odds of having a larger reduction in tinnitus severity (OR 3.47; 95% CI 1.32 to 12.51), compared with the participants who had education only up to high school or less. Additionally, the baseline tinnitus severity was found to be a significant variable (OR 2.65; 95% CI 1.50 to 4.67) contributing to a successful outcome with the intervention. Both linear and logistic regression models have identified education level and baseline tinnitus severity to be significant predictor variables contributing to a reduction in tinnitus severity post-ICBT. As per the linear regression model, participants who had received disability allowance had shown a 25.3-point lower TFI reduction compared with those who did not experience a decrease in their workload due to tinnitus after adjusting for baseline tinnitus severity and their education level.ConclusionsPredictors of intervention outcome can be used as a means of triaging patients to the most suited form of treatment to achieve optimal outcomes and to make healthcare savings. Future studies should consider including a heterogeneous group of participants as well as other predictor variables not included in the current study.ClinicalTrial.gov Registration: NCT02370810 (completed); NCT02665975 (completed).

Project description:ObjectivesInternet-delivered exposure-based cognitive behaviour therapy (ICBT) has been shown to be effective in the treatment of severe health anxiety. The health economic effects of the treatment have, however, been insufficiently studied and no prior study has investigated the effect of ICBT compared with an active psychological treatment. The aim of the present study was to investigate the cost effectiveness of ICBT compared with internet-delivered behavioural stress management (IBSM) for adults with severe health anxiety defined as Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) hypochondriasis. ICBT was hypothesised to be the more cost-effective treatment.SettingThis was a cost-effectiveness study within the context of a randomised controlled trial conducted in a primary care/university setting. Participants from all of Sweden could apply to participate.ParticipantsSelf-referred adults (N=158) with a principal diagnosis of DSM-IV hypochondriasis, of whom 151 (96%) provided baseline and post-treatment data.InterventionsICBT or IBSM for 12 weeks.Primary and secondary measuresThe primary outcome was the Health Anxiety Inventory. The secondary outcome was the EQ-5D. Other secondary measures were used in the main outcome study but were not relevant for the present health economic analysis.ResultsBoth treatments led to significant reductions in gross total costs, costs of healthcare visits, direct non-medical costs and costs of domestic work cutback (p=0.000-0.035). The incremental cost-effectiveness ratio (ICER) indicated that the cost of one additional case of clinically significant improvement in ICBT compared with IBSM was $2214. The cost-utility ICER, that is, the cost of one additional quality-adjusted life year, was estimated to be $10,000.ConclusionsICBT is a cost-effective treatment compared with IBSM and treatment costs are offset by societal net cost reductions in a short time. A cost-benefit analysis speaks for ICBT to play an important role in increasing access to effective treatment for severe health anxiety.Trial registration numberNCT01673035; Results.

Project description:BackgroundInternet-based cognitive behavioural therapy (iCBT) is an effective and acceptable treatment for depression, especially when it includes guidance, but its treatment adherence has not yet been systematically studied. We conducted a meta-analysis, comparing the adherence to guided iCBT with the adherence to individual face-to-face CBT.MethodsStudies were selected from a database of trials that investigate treatment for adult depression (see www.evidencebasedpsychotherapies.org), updated to January 2013. We identified 24 studies describing 26 treatment conditions (14 face-to-face CBT, 12 guided iCBT), by means of these inclusion criteria: targeting depressed adults, no comorbid somatic disorder or substance abuse, community recruitment, published in the year 2000 or later. The main outcome measure was the percentage of completed sessions. We also coded the percentage of treatment completers (separately coding for 100% or at least 80% of treatment completed).ResultsWe did not find studies that compared guided iCBT and face-to-face CBT in a single trial that met our inclusion criteria. Face-to-face CBT treatments ranged from 12 to 28 sessions, guided iCBT interventions consisted of 5 to 9 sessions. Participants in face-to-face CBT completed on average 83.9% of their treatment, which did not differ significantly from participants in guided iCBT (80.8%, P ?=? .59). The percentage of completers (total intervention) was significantly higher in face-to-face CBT (84.7%) than in guided iCBT (65.1%, P < .001), as was the percentage of completers of 80% or more of the intervention (face-to-face CBT: 85.2%, guided iCBT: 67.5%, P ?=? .003). Non-completers of face-to-face CBT completed on average 24.5% of their treatment, while non-completers of guided iCBT completed on average 42.1% of their treatment.ConclusionWe did not find studies that compared guided iCBT and face-to-face CBT in a single trial. Adherence to guided iCBT appears to be adequate and could be equal to adherence to face-to-face CBT.
