Clinical and cost-effectiveness of computerised cognitive behavioural therapy for depression in primary care: design of a randomised trial

Long-term outcomes of acute treatment with cognitive therapy v. interpersonal psychotherapy for adult depression: follow-up of a randomized controlled trial

BACKGROUND

Although equally efficacious in the acute phase, it is not known how cognitive therapy (CT) and interpersonal psychotherapy (IPT) for major depressive disorder (MDD) compare in the long run. This study examined the long-term outcomes of CT v. IPT for MDD.

METHODS

One hundred thirty-four adult (18-65) depressed outpatients who were treated with CT (n = 69) or IPT (n = 65) in a large open-label randomized controlled trial (parallel group design; computer-generated block randomization) were monitored across a 17-month follow-up phase. Mixed regression was used to determine the course of self-reported depressive symptom severity (Beck Depression Inventory II; BDI-II) after treatment termination, and to test whether CT and IPT differed throughout the follow-up phase. Analyses were conducted for the total sample (n = 134) and for the subsample of treatment responders (n = 85). Furthermore, for treatment responders, rates of relapse and sustained response were examined for self-reported (BDI-II) and clinician-rated (Longitudinal Interval Follow-up Evaluation; LIFE) depression using Cox regression.

RESULTS

On average, the symptom reduction achieved during the 7-month treatment phase was maintained across follow-up (7-24 months) for CT and IPT, both in the total sample and in the responder sample. Two-thirds (67%) of the treatment responders did not relapse across the follow-up period on the BDI-II. Relapse rates assessed with the LIFE were somewhat lower. No differential effects between conditions were found.

CONCLUSIONS

Patients who responded to IPT were no more likely to relapse following treatment termination than patients who responded to CT. Given that CT appears to have a prophylactic effect following successful treatment, our findings suggest that IPT might have a prophylactic effect as well.

Cost-effectiveness analysis of internet-mediated cognitive behavioural therapy for depression in the primary care setting: results based on a controlled trial

OBJECTIVE

To perform a cost-effectiveness analysis of a randomised controlled trial of internet-mediated cognitive behavioural therapy (ICBT) compared with treatment as usual (TaU) for patients with mild to moderate depression in the Swedish primary care setting. In particular, the objective was to assess from a healthcare and societal perspective the incremental cost-effectiveness ratio (ICER) of ICBT versus TaU at 12 months follow-up.

DESIGN

A cost-effectiveness analysis alongside a pragmatic effectiveness trial.

SETTING

Sixteen primary care centres (PCCs) in south-west Sweden.

PARTICIPANTS

Ninety patients diagnosed with mild to moderate depression at the PCCs.

MAIN OUTCOME MEASURE

ICERs calculated as (Cost_ICBT-Cost_TaU)/(Health outcome_ICBT-Health outcome_TaU)=ΔCost/ΔHealth outcomes, the health outcomes being changes in the Beck Depression Inventory-II (BDI-II) score and quality-adjusted life-years (QALYs).

RESULTS

The total cost per patient for ICBT was 4044 Swedish kronor (SEK) (€426) (healthcare perspective) and SEK47 679 (€5028) (societal perspective). The total cost per patient for TaU was SEK4434 (€468) and SEK50 343 (€5308). In both groups, the largest cost was associated with productivity loss. The differences in cost per patient were not statistically significant. The mean reduction in BDI-II score was 13.4 and 13.8 units in the ICBT and TaU groups, respectively. The mean QALYs per patient was 0.74 and 0.79 in the ICBT and TaU groups, respectively. The differences in BDI-II score reduction and mean QALYs were not statistically significant. The uncertainty of the study estimates when assessed by bootstrapping indicated that no firm conclusion could be drawn as to whether ICBT treatment compared with TaU was the most cost-effective use of resources.

CONCLUSIONS

ICBT was regarded to be as cost-effective as TaU as costs, health outcomes and cost-effectiveness were similar for ICBT and TaU, both from a healthcare and societal perspective.

e-CBT (myCompass), Antidepressant Medication, and Face-to-Face Psychological Treatment for Depression in Australia: A Cost-Effectiveness Comparison

Background

The economic cost of depression is becoming an ever more important determinant for health policy and decision makers. Internet-based interventions with and without therapist support have been found to be effective options for the treatment of mild to moderate depression. With increasing demands on health resources and shortages of mental health care professionals, the integration of cost-effective treatment options such as Internet-based programs into primary health care could increase efficiency in terms of resource use and costs.

Objective

Our aim was to evaluate the cost-effectiveness of an Internet-based intervention (myCompass) for the treatment of mild-to-moderate depression compared to treatment as usual and cognitive behavior therapy in a stepped care model.

Methods

A decision model was constructed using a cost utility framework to show both costs and health outcomes. In accordance with current treatment guidelines, a stepped care model included myCompass as the first low-intervention step in care for a proportion of the model cohort, with participants beginning from a low-intensity intervention to increasing levels of treatment. Model parameters were based on data from the recent randomized controlled trial of myCompass, which showed that the intervention reduced symptoms of depression, anxiety, and stress and improved work and social functioning for people with symptoms in the mild-to-moderate range.

Results

The average net monetary benefit (NMB) was calculated, identifying myCompass as the strategy with the highest net benefit. The mean incremental NMB per individual for the myCompass group was AUD 1165.88 compared to treatment as usual and AUD 522.58 for the cognitive behavioral therapy model.

Conclusions

Internet-based interventions can provide cost-effective access to treatment when provided as part of a stepped care model. Widespread dissemination of Internet-based programs can potentially reduce demands on primary and tertiary services and reduce unmet need.

Use of the internet to assist in the treatment of depression and anxiety: a systematic review

OBJECTIVE

This systematic review aims to describe the Internet's potential role in assisting patients with depression and anxiety.

DATA SOURCES

A MEDLINE search was conducted of articles published between 1998 and 2008 using the terms depression and anxiety and Internet, computers and depression and anxiety, Internet and compliance and depression, and Internet and adherence and depression.

STUDY SELECTION

Publications cited include articles concerned with the Internet in screening, supporting, educating, and treating patients with depression and anxiety.

DATA EXTRACTION

The efficacy of Internet-based interventions for depression and anxiety was reviewed, alongside the quality of available online information regarding these disorders.

DATA SYNTHESIS

Little progress has been made in developing a universally accepted system for quality assurance of medical information Web sites. Furthermore, there is a lack of research describing the effect of self-diagnosis sites on meaningful outcomes, such as the proportion of patients who go on to receive successful treatment for their depression. Early studies of Internet-based cognitive-behavioral therapy for depression were promising; however, results of clinical trials for "e-therapy" have been variable due to methodological issues. A novel compliance support Web site for patients with depression and anxiety is being evaluated to establish whether providing such assistance can improve patient outcomes.

CONCLUSIONS

The use of the Internet to assist patients with depression and anxiety is currently in its infancy. However, it appears that the Internet has great potential to support patients with depression and may consequently also be of benefit to physicians.

What do service users with bipolar disorder want from a web-based self-management intervention? A qualitative focus group study

BACKGROUND

Bipolar disorder (BD) is a chronic and recurrent severe mental health problem. A web-based self-management intervention provides the opportunity to widen access to psychological interventions. This qualitative study aims to identify what an ideal web-based intervention would look like for service users with BD.

METHODS

Twelve service users with BD were recruited in the UK and took part in a series of focus groups to inform and refine the development of a web-based self-management intervention. Reported here is a subset analysis of data gathered with the primary aim of identifying the needs and desires of service users for such an intervention for BD. We analysed service users' responses to questions about content, outcomes, format, barriers and support. Focus groups were transcribed verbatim, and thematic analysis was employed.

RESULTS

The data were ordered into four key themes: (1) gaining an awareness of and managing mood swings; (2) not just about managing mood swings: the importance of practical and interpersonal issues; (3) managing living within mood swings without losing the experience; (4) internet is the only format: freely accessible, instant and interactive; (5) professional and peer support to overcome low motivation and procrastination difficulties.

LIMITATIONS

The small group of participants are not representative of those living with BD.

CONCLUSIONS

These findings have significantly enhanced our understanding of what service users with BD want from a web-based self-management intervention and have clear implications for the future development of such approaches.

KEY PRACTITIONER MESSAGE

Service users desire a web-based self-management approach that gives them the techniques they need to not only manage their moods but also manage their lives alongside the disorder, including interpersonal and practical issues. Service users describe their primary outcome, not as a cure or reduction in their symptoms, but instead being able to live a fulfilling life alongside their condition. Service users see the internet as their preferred format because of the increased accessibility to evidence-based intervention. Service users discussed the potential barriers to web-based interventions including motivation and procrastination. Effective and acceptable content and low-level support provide potential solutions to these issues.

A randomized controlled trial of the efficacy and cost-effectiveness of a brief intensified cognitive behavioral therapy and/or pharmacotherapy for mood and anxiety disorders: design and methods

BACKGROUND

Anxiety and mood disorders involve a high disease burden and are associated with high economic costs. A stepped-care approach intervention and abbreviated diagnostic method are assumed to increase effectiveness and efficiency of the mental healthcare and are expected to reduce economic costs.

METHODS

Presented are the rationale, design, and methods of a two-armed randomized controlled trial comparing 'treatment as usual' (TAU) with a brief intensified cognitive behavioral therapy (CBT) and/or pharmacotherapy. Eligible participants (N=500) of five Dutch outpatient Mental Healthcare Centers are randomly assigned to either TAU or to the experimental condition (brief CBT and/or pharmacotherapy). Data on patients' progress and clinical effectiveness of treatment are assessed at baseline, post-treatment (3 months after baseline), and at 6 and 12 months post-treatment by Routine Outcome Monitoring (ROM). Cost analysis is performed on the obtained data.

DISCUSSION

Since few studies have investigated both the clinical and cost effectiveness of a stepped-care approach intervention and a shortened diagnostic ROM method in both anxiety and/or mood disorders within secondary mental health care, the results of this study might contribute to the improvement of (cost)-effective treatment options and diagnostic methods for these disorders.

The responsiveness of quality of life utilities to change in depression: a comparison of instruments (SF-6D, EQ-5D, and DFD)

BACKGROUND

Utilities are often a main outcome parameter in economic evaluations. Because depression has a large influence on quality of life, it is expected that utilities are responsive to changes in depression.

OBJECTIVE

To evaluate the change in utility derived from different instruments in depression, including the Short Form 6D (SF-6D), the Euroqol based on the UK (EQ-5D(UK)), the Euroqol based on the Dutch tariff (EQ-5D(NL)), and utilities derived from Beck Depression Inventory Second Edition (BDI-II) using the Depression-Free-Day method.

METHOD

This study evaluated the responsiveness, the minimally important difference, and the agreement in utility change derived from the different instruments.

RESULTS

The SF-6D, EQ-5D(UK), and EQ-5D(NL) were responsive. The minimally important difference values are in line with previous studies, about 0.3. The Depression-Free-Day method nearly always resulted in positive utility changes, even for subgroups that had no change or deterioration in health status or depression. There was poor agreement between utility changes of the SF-6D, EQ-5D (either EQ-5D(UK) or EQ-5D(NL)), and DFDu.

CONCLUSIONS

The SF-6D, EQ-5D(UK), and EQ-5D(NL) seem responsive and thus adequate for estimating utility in depression treatment. We do not recommend the use of the Depression-Fee-Day method. The low agreement between utility changes indicates that outcomes of the different instruments are incomparable.

Effectiveness, relapse prevention and mechanisms of change of cognitive therapy vs. interpersonal therapy for depression: Study protocol for a randomised controlled trial

Background

Major depression is a common mental disorder that substantially impairs quality of life and has high societal costs. Although psychotherapies have proven to be effective antidepressant treatments, initial response rates are insufficient and the risk of relapse and recurrence is high. Improvement of treatments is badly needed. Studying the mechanisms of change in treatment might be a good investment for improving everyday mental health care. However, the mechanisms underlying therapeutic change remain largely unknown. The objective of the current study is to assess both the effectiveness of two commonly used psychotherapies for depression in terms of reduction of symptoms and prevention of relapse on short and long term, as well as identifying underlying mechanisms of change.

Methods

In a randomised trial we will compare (a) Cognitive Therapy (CT) with (b) Interpersonal therapy (IPT), and (c) an 8-week waiting list condition followed by treatment of choice. One hundred eighty depressed patients (aged 18-65) will be recruited in a mental health care centre in Maastricht (the Netherlands). Eligible patients will be randomly allocated to one of the three intervention groups. The primary outcome measure of the clinical evaluation is depression severity measured by the Beck Depression Intenvory-II (BDI-II). Other outcomes include process variables such as dysfunctional beliefs, negative attributions, and interpersonal problems. All self-report outcome assessments will take place on the internet at baseline, three, seven, eight, nine, ten, eleven, twelve and twenty-four months. At 24 months a retrospective telephone interview will be administered. Furthermore, a rudimentary analysis of the cost-effectiveness will be embedded. The study has been ethically approved and registered.

Discussion

By comparing CT and IPT head-to-head and by investigating multiple potential mediators and outcomes at multiple time points during and after therapy, we hope to provide new insights in the effectiveness and mechanisms of change of CT and IPT for depression, and contribute to the improvement of mental health care for adults suffering from depression.

Trial registration

The study has been registered at the Netherlands Trial Register, part of the Dutch Cochrane Centre (ISRCTN67561918)

Recruitment into a guided internet based CBT (iCBT) intervention for depression: lesson learnt from the failure of a prevalence recruitment strategy

INTRODUCTION

Internet based Cognitive Behavioural Therapy (iCBT) represents a significant development in the way psychological interventions are delivered. Studies tend to recruit via common media channels leading to criticisms of biased sample sizes and limited generalisability to primary care settings.

AIM

To evaluate the use of a prevalence recruitment strategy within primary care to recruit into an RCT examining a free to use iCBT intervention.

METHODS

Fully randomised controlled trial (RCT), utilising a prevalence based recruitment strategy, comparing the iCBT intervention with telephone support provided by NHS Direct Health Advisors with treatment-as-usual (TAU) control.

RESULTS

Recruitment rates were low with only 7 participants recruited over 8 months. Overall only 14% of expected study invitations were sent, with only 1% undertaking the consent and initial screening process.

DISCUSSION

Key differences with successful prevalence recruitment strategies highlight four main issues to consider when recruiting participants from primary care into iCBT studies--lack of equipoise, a need for an assertive approach, coding of depression in GP databases and help seeking behaviour in depression which can all act as potential contributors to failure to recruit. However other non-primary care recruitment methods, such as the use of media channels, which are already shown to be effective in non-primary care settings should be considered if these methods more accurately target the population who would be willing to adopt iCBT more generally.

Improving adherence and effectiveness of computerised cognitive behavioural therapy without support for depression: a qualitative study on patient experiences

BACKGROUND

Several studies have evaluated the efficacy and effectiveness of computerized cognitive behavioural therapy (CCBT) for depression, but research on the patient perspective is limited.

AIMS

To gain knowledge on patient experiences with the online self-help CCBT program Colour Your Life (CYL) for depression, and find explanations for the low treatment adherence and effectiveness.

METHOD

Qualitative data were collected through semi-structured interviews with 18 patients. Interviewees were selected from a CCBT trial. An inductive, content analysis of the interviews was performed.

RESULTS

The main theme throughout the interviews concerns barriers and motivators experienced with CCBT. The most important barriers included experiences of a lack of identification with and applicability of CCBT-CYL, lack of support to adhere with the program or to gain deeper understanding, and inadequate computer/Internet skills, equipment, or location. Confusion between CCBT and Internet questionnaires resulted in no CCBT uptake of some study participants. Motivators included experiencing self-identification and improvement through CCBT-CYL, participating in a scientific study, and the freedom and anonymity associated with online computer self-help. The addition of support to CCBT was suggested as an improvement towards adherence and the course content.

CONCLUSION

The CCBT program CYL in its current form does not work for a large group of people with depressive symptoms. More tailoring, the provision of support (professional or lay) and good computer conditions could improve CCBT.

One-year follow-up results of unsupported online computerized cognitive behavioural therapy for depression in primary care: A randomized trial

OBJECTIVE

To report the one-year follow-up results of computerized cognitive behavioural therapy (CCBT), offered online without professional support, for depression compared with usual GP care and a combination of both treatments. To explore potential relapse prevention effects of CCBT.

METHODS

303 depressed patients were randomly allocated to (a) unsupported online CCBT (b) treatment as usual (TAU), or (c) CCBT and TAU combined. We had a 12-month follow-up period. Primary outcome measure was the Beck Depression Inventory II. Self-reported health care use was also measured.

KEY FINDINGS

At 12 months, no statistically significant differences between the three interventions are found in the intention-to-treat population for depressive severity, reliable improvement, remission, and relapse. In the first quarter, differences in health care consumption between the three interventions are significant (i.e. less GP contacts, less antidepressant medication, and less specialist mental health care in the CCBT group), but these differences disappear over time.

CONCLUSIONS

Unsupported online CCBT is not superior to TAU by a GP for depression. With equal effects, CCBT alone leads to less health care consumption than TAU and CCBT&TAU. Overall effects are modest in all interventions, which can be explained by the finding that the use of health care services decreases despite the lack of substantial improvements.

Feasibility of an eHealth service to support collaborative depression care: results of a pilot study

BACKGROUND

Treatments and organizational changes supported by eHealth are beginning to play an important role in improving disease treatment outcome and providing cost-efficient care management. "Improvehealth.eu" is a novel eHealth service to support the treatment of patients with depressive disorder. It offers active patient engagement and collaborative care management by combining Web- and mobile-based information and communication technology systems and access to care managers.

OBJECTIVES

Our objective was to assess the feasibility of a novel eHealth service.

METHODS

The intervention--the "Improvehealth.eu" service--was explored in the course of a pilot study comparing two groups of patients receiving treatment as usual and treatment as usual with eHealth intervention. We compared patients' medication adherence and outcome measures between both groups and additionally explored usage and overall perceptions of the intervention in intervention group.

RESULTS

The intervention was successfully implemented in a pilot with 46 patients, of whom 40 were female. Of the 46 patients, 25 received treatment as usual, and 21 received the intervention in addition to treatment as usual. A total of 55% (12/25) of patients in the former group and 45% (10/21) in the latter group finished the 6-month pilot. Available case analysis indicated an improvement of adherence in the intervention group (odds ratio [OR] = 10.0, P = .03). Intention-to-treat analysis indicated an improvement of outcome in the intervention group (ORs ranging from 0.35 to 18; P values ranging from .003 to .20), but confidence intervals were large due to small sample sizes. Average duration of use of the intervention was 107 days. The intervention was well received by 81% (17/21) of patients who reported feeling actively engaged, in control of their disease, and that they had access to a high level of information. In all, 33% (7/21) of the patients also described drawbacks of the intervention, mostly related to usability issues.

CONCLUSIONS

The results of this pilot study indicate that the intervention was well accepted and helped the patients in the course of treatment. The results also suggest the potential of the intervention to improve both medication adherence and outcome measures of treatment, including reduction of depression severity and patients becoming "healthy."

Guided self-help on the Internet for Turkish migrants with depression: the design of a randomized controlled trial

Background

The Turkish population living in the Netherlands has a high prevalence of psychological complaints and has a high threshold for seeking professional help for these problems. Seeking help through the Internet can overcome these barriers. This project aims to evaluate the effectiveness of a guided self-help problem-solving intervention for depressed Turkish migrants that is culturally adapted and web-based.

Methods

This study is a randomized controlled trial with two arms: an experimental condition group and a wait list control group. The experimental condition obtains direct access to the guided web-based self-help intervention, which is based on Problem Solving Treatment (PST) and takes 6 weeks to complete. Turkish adults with mild to moderate depressive symptoms will be recruited from the general population and the participants can choose between a Turkish and a Dutch version. The primary outcome measure is the reduction of depressive symptoms, the secondary outcome measures are somatic symptoms, anxiety, acculturation, quality of life and satisfaction. Participants are assessed at baseline, post-test (6 weeks), and 4 months after baseline. Analysis will be conducted on the intention-to-treat sample.

Discussion

This study evaluates the effectiveness of a guided problem-solving intervention for Turkish adults living in the Netherlands that is culturally adapted and web-based.

Discrepancy in rating health-related quality of life of depression between patient and general population

OBJECTIVE

To compare the quality of life valuation of a hypothetical depression health state between a general population versus a depressive patient population, and within a patient population.

METHOD

In a self-administered Internet questionnaire, both patient and general population groups filled in the Euroqol 5D (EQ-5D) questionnaire for a hypothetical depression health state describing mild (N = 740), moderate (N = 691), or severe (N = 670) depression and valued it using a rating scale (RS). The 'patient' group consisted of people reporting depressive complaints on the Internet questionnaire, subdivided into three depression severity groups (mild, moderate, severe) based on the Beck Depression Inventory Second Edition (BDI-II) and two groups according to self-perceived duration (≤ 3 months, ≥ 4 months) of depressive complaints (SPDD).

RESULTS

Significant differences were found between the patient and general population and within the patient population on RS outcomes and on the Euroqol domains usual activities, pain/discomfort, and anxiety/depression. The direction of the differences shows that subgroups with higher severity or longer duration of depressive complaints value depression health states worse compared with subgroups with less severe complaints, a shorter duration, or no depressive complaints. Moreover, the discrepancy in valuation of a health state between different subgroups changes according to the severity of the health state described.

CONCLUSION

There are discrepancies in the valuation of a hypothetical depression health state between a patient and general population, whereby depression leads to a worse valuation. But also within the patient population, the valuation differs according to depression severity and duration. Identification with the hypothetical health state description might explain the varying differences found between subgroups for the different hypothetical health state descriptions.

Minor and major depression in the general population: does dysfunctional thinking play a role?

BACKGROUND

Although most research suggests that minor depression is part of a depression continuum, conflicting results have also been found. Moreover, little is known about dysfunctional thinking in minor depression and how this varies along the continuum. Especially, research on the form of dysfunctional thinking (ie, extreme responding) is lacking. We have addressed these issues by reporting results from a large community sample.

METHODS

Demographic, clinical, and cognitive factors (ie, content and form of dysfunctional thinking) were compared between minor depression (ie, 2-4 symptoms), major depression with 5 to 6 symptoms, and major depression with 7 to 9 symptoms. A large community sample (N = 1129) was used. Differences between the 3 subgroups were examined as well as linear relations between number of symptoms and factors marking the severity.

RESULTS

Most demographic variables did not distinguish the 3 depression status categories from each other. Clinical and cognitive factors acted in synchrony with the depression continuum.

CONCLUSIONS

Minor depression should be considered as part of continuum together with major depression. Not only the content but also the form of dysfunctional thinking seems to play a major role in depression. Extreme positive responding is more prominent in mild depression, whereas more severely depressed individuals have a general tendency toward extreme negative responding. This finding, if replicated, may have important implications for the cognitive theory of depression.

Economic evaluation of online computerised cognitive-behavioural therapy without support for depression in primary care: randomised trial

BACKGROUND

Evidence about the cost-effectiveness and cost utility of computerised cognitive-behavioural therapy (CCBT) is still limited. Recently, we compared the clinical effectiveness of unsupported, online CCBT with treatment as usual (TAU) and a combination of CCBT and TAU (CCBT plus TAU) for depression. The study is registered at the Netherlands Trial Register, part of the Dutch Cochrane Centre (ISRCTN47481236).

AIMS

To assess the cost-effectiveness of CCBT compared with TAU and CCBT plus TAU.

METHOD

Costs, depression severity and quality of life were measured for 12 months. Cost-effectiveness and cost-utility analyses were performed from a societal perspective. Uncertainty was dealt with by bootstrap replications and sensitivity analyses.

RESULTS

Costs were lowest for the CCBT group. There are no significant group differences in effectiveness or quality of life. Cost-utility and cost-effectiveness analyses tend to be in favour of CCBT.

CONCLUSIONS

On balance, CCBT constitutes the most efficient treatment strategy, although all treatments showed low adherence rates and modest improvements in depression and quality of life.

Innovative psychosocial approaches in old age psychiatry

PURPOSE OF REVIEW

To identify and discuss recent research studies that propose innovative psychosocial interventions in old age psychiatry.

RECENT FINDINGS

Studies have shown that cognitive training research for healthy elderly has advanced in several ways, particularly in the refinement of study design and methodology. Studies have included larger samples and longer training protocols. Interestingly, new research has shown changes in biological markers associated with learning and memory after cognitive training. Among mild cognitive impairment patients, results have demonstrated that they benefit from interventions displaying cognitive plasticity.Rehabilitation studies involving dementia patients have suggested the efficacy of combined treatment approaches, and light and music therapies have shown promising effects. For psychiatric disorders, innovations have included improvements in well known techniques such as cognitive behavior therapy, studies in subpopulations with comorbidities, as well as the use of new computer-aided resources.

SUMMARY

Research evidence on innovative interventions in old age psychiatry suggests that this exciting field is moving forward by means of methodological refinements and testing of creative new ideas.

Use and acceptability of unsupported online computerized cognitive behavioral therapy for depression and associations with clinical outcome

BACKGROUND

In a recent randomized trial, we were unable to confirm the previously reported high effectiveness of CCBT. Therefore, the aim of the current study was to have a closer look at usage and acceptability (i.e. expectancy, credibility, and satisfaction) of the intervention.

METHODS

Depressed participants (N=200) were given login codes for unsupported online CCBT. A track-and-trace system tracked which components were used. We used a 9-month follow-up period.

RESULTS

Uptake was sufficient, but dropout was high. Many usage indices were positively associated with short-term depressive improvement, whereas only homework was related to long-term improvement. Acceptability was good and expectancy could predict long-term, but not short-term outcome.

LIMITATIONS

Associations between use of CCBT and improvement are merely correlational. Our sample was too depressed in relation to the scope of the intervention. We relied on online self-report measures. Analyses were exploratory in nature.

CONCLUSIONS

Although CCBT might be a feasible and acceptable treatment for depression, means to improve treatment adherence are needed for moderately to severely depressed individuals.

Clinical effectiveness of online computerised cognitive-behavioural therapy without support for depression in primary care: randomised trial

BACKGROUND

Computerised cognitive-behavioural therapy (CCBT) might offer a solution to the current undertreatment of depression.

AIMS

To determine the clinical effectiveness of online, unsupported CCBT for depression in primary care.

METHOD

Three hundred and three people with depression were randomly allocated to one of three groups: Colour Your Life; treatment as usual (TAU) by a general practitioner; or Colour Your Life and TAU combined. Colour Your Life is an online, multimedia, interactive CCBT programme. No assistance was offered. We had a 6-month follow-up period.

RESULTS

No significant differences in outcome between the three interventions were found in the intention-to-treat and per protocol analyses.

CONCLUSIONS

Online, unsupported CCBT did not outperform usual care, and the combination of both did not have additional effects. Decrease in depressive symptoms in people with moderate to severe depression was moderate in all three interventions. Online CCBT without support is not beneficial for all individuals with depression.
