The BlendedCare Project


Internet based cognitive behavioural therapy (iCBT) has been demonstrated to be cost- and clinically effective. There is a need, however, for increased therapist contact for some patient groups. Combining iCBT with traditional face-to-face (ftf) consultations in a blended format may produce a new treatment format with multiple benefits from both traditional CBT and iCBT such as individual adaptation, lower costs than traditional therapy, wide geographical and temporal availability, and lower threshold to implementation.


The primary aim of the present study is to compare directly the clinical effectiveness of B-CBT with face-to-face (FTF) CBT for adult major depressive disorder.


The study is designed as a two-arm randomised controlled non-inferiority trial comparing blended CBT for adult depression with treatment as usual (TAU). In the blended condition six sessions of FTF CBT is alternated with six to eight online modules (NoDep). TAU is defined as twelve sessions of FTF CBT. The primary outcome is symptomatic change of depressive symptoms on the patient-health questionnaire (PHQ-9).

Additionally, the study will include an economic evaluation. All participants must be eighteen years of age or older and meet the diagnostic criteria for major depressive disorder according to the Diagnostic and Statistical Manual of Mental disorders 4th edition. Participants are randomised on an individual level by a researcher not involved in the project. The primary outcome is analysed by a multilevel mixed effects model using time as independent variable and PHQ-9 as the dependent variable. Baseline scores, weekly measures and three and six-month follow-up scores will all be included using maximum likelihood estimation of all available data.


This study will compare B-CBT and FTF therapy in a concise and direct manner with only a minimal of the variance explained by differences in therapeutic content. On the other hand, while situated in routine care, ecological validity is somewhat compromised by the controlled manner in which the study is conducted.

The ENTER program consists of five research projects that aim to:

  1. Develop novel technologies and forms of service delivery improving treatment outcomes for patients within a mental health care setting.
  2. Provide evidence for the clinical and cost effective benefits and possible risks of using technologies in mental health care services.
  3. Enable ENTER´s industry partners to market their products nationally and internationally based on the proven feasibility of the technologies.
  4. Disseminate research results directed at the patient organisations and policy makers in mental health care, and representatives of multiple bodies of clinical practice – pending clinical efficacy, successful implementation in the care and management of patients with mental disorders and mental health problems.
  5. Establish a fruitful, collaborative research environment for e-mental health research with a national networking organization to persist beyond the present project.
