Study hypothesis

The study aims to determine the effectiveness, cost-effectiveness and cost implications of brief vs. extended support given by clinicians vs. assistants as an adjunct to computerised Cognitive Behavioural Therapy (cCBT). It will also examine if such support could be tailored to suit different patients’ needs and preferences in order to achieve optimal clinical outcomes with cCBT within the budget constraints of the NHS. The sample will include 300 patients with non-suicidal depression who are 18 years old or above, are registered with a GP within NHS Norfolk. Suitable patients who agree to participate in the study will be randomly allocated in a 1:1 ratio to an 8-session cCBT programme, called Beating the Blues, which can be accessed via the internet from patients’ homes or at public venues (e.g. libraries, internet cafes). Patients will receive phone support as an adjunct to cCBT either by a clinician (CBT-trained health professional with an active registration) or by an assistant (graduate mental health worker with no clinical qualifications. Support will be provided once a week for the first 6 weeks, once a fortnight for the following 6 weeks and once a month for the following 3 months (a total of 12 phone support sessions over 6 months). The clinician- vs. assistant-supported groups will be further randomised in a 1:1 ratio to receive sessions that are either brief (5-10 min per session) or extended (20-10 min per session). Patients will have a total of 1-2 hrs brief support or 4-6 hrs extended support over 6 months. Data on clinical outcomes (depression and anxiety symptoms, functioning, quality of life) and on healthcare resource and service use will be collected with self-report standardised measures which will be posted to the patients for completion at baseline (week 0) and then at two follow-up points (approx. at weeks 12 and 24 post-randomisation). Interviews will be carried out about patient experiences at approx. 12 weeks post-randomisation.

Topic: Mental Health Research Network, Primary Care Research Network for England; Subtopic: Depression, Not Assigned; Disease: Depression


cCBT + phone support, The computerised cCBT system used in this study is Beating the Blues (BtB). During eight 50-minute sessions, BtB teaches patients how to identify unhelpful thoughts and come up with helpful alternatives, and how to do activity scheduling, problem-solving and other relevant homework tasks between their computer sessions. Patients are also offered individual support as a single, scheduled, telephone call once a week for the first 6 weeks, then once a fortnight for a subsequent 6 weeks; Follow Up Length: 6 month(s); Study Entry : Single Randomisation only

Participant inclusion criteria

The main criterion for patients to be included in the study is that their primary problem is:
1. Nonsuicidal, nonpsychotic, unipolar mood disorder, such as depression or dysthymia: the key features are low mood, loss of interest/pleasure and/or increased fatigue/low energy for more than 2 weeks. Secondary features can be: feelings of guilt and self-reproach, emotional blunting, loss of confidence, psychomotor retardation or agitation, problems with memory or concentration, changes in weight & appetite, sleep problems, irritability, loss of libido
2. Mixed anxiety and depressive disorder: this condition is very common in primary care and shares key features of both depression (as above) and generalised anxiety (key features: 6 months of tension, worry, apprehension paniclike physical symptoms) but neither cluster of symptoms is clearly predominant and present to the extent that justifies separate diagnoses of a depressive episode or generalised anxiety disorder.
3. Additional inclusion criteria that need to be met so that patients can participate in the study are:
3.1. Signing a written consent form for screening & treatment
3.2. Having a general practitioner (GP) within NHS Norfolk (which does not include Great Yarmouth & Waveney) or being cared for by a service/facility commissioned by NHS Norfolk. In case of University of East Anglia (UEA) students, they would need to have a temporary GP within NHS Norfolk.
3.3. Being 18 years old or above.; Target Gender: Male & Female ; Lower Age Limit 18 years

Target number of participants

Planned Sample Size: 300; UK Sample Size: 300

Participant exclusion criteria

1. High current risk of suicide (current suicide plans and intent to harm oneself). In this case, referral to a community mental health or crisis team should be a priority
2. Current psychotic symptoms (due to schizophrenia or bipolar affective disorder or severe depression with psychotic features)
3. Current substance abuse/misuse (alcohol, illicit drugs, tranquilisers) which needs to be addressed as a priority
4. Cognitive impairment which makes difficult the use of a computer, doing homework, etc
5. Any other primary problem (e.g. posttraumaticstress disorder, obsessive compulsive disorder) which needs to be treated as a priority but which may have depression as a comorbid feature
