Plain English Summary
Background and study aims
Depression and anxiety are common mental health problems. There are effective treatments for depression and anxiety and one of these is talking therapies using a technique called cognitive behavioural therapy (CBT). CBT is a type of therapy that helps people to change the way they think and behave. In recent years internet-delivered CBT has emerged as an alternative to face-to-face psychological services, and it has proven to be successful in treating people with depression and anxiety. SilverCloud is an innovative online behavioral health and wellness e-therapy delivery platform. It enables healthcare organisations to deliver a broad range of highly engaging and interactive online behavioral and long-term illness content, programs and support to their clients and patients. SilverCloud is proven to improve clinical/patient outcomes, dramatically reduce the cost of behavioral health delivery/support, increase scalability/reach and increase access. The aim of this study is to evaluate the effectiveness and cost-effectiveness of this program in improving the symptoms of depression and anxiety disorders.
Who can participate?
Adults who are suffering from depression or anxiety.
What does the study involve?
Participants are randomly allocated to one of two groups. Those in the first group receive immediate treatment with internet-delivered CBT for either depression or anxiety. Those in the second group receive the treatment after an eight week wait. At the start of the study and then after three, six, nine and twelve months, participants in both groups complete a range of questionnaires to assess their mental wellbeing, to find out if they have benefited from the treatment.
What are the possible benefits and risks of participating?
Participants may benefit from receiving the treatment, which could help improve their symptoms. There are no notable risks involved with participating.

Depression and anxiety disorders
Post diagnostic assessment participants will be randomised to either the immediate treatment (depression or anxiety) or a waiting list control group using random permuted blocks using block sizes of 9 and including stratification within a 2:1 ratio between treatment groups – depression and anxiety - and the waiting list control group.
Immediate treatment group: Participants will be assigned to either the Space from Deopression or the Space from Anxiety interventions and they will be encouraged to use the intervention over 8 weeks and they will receive up to 6 online reviews from their clinician supporter over that time. Data will be collected at baseline, continuously at each session, at 8 weeks and at 3, 6, 9 and 12 months follow-up.
Space from Depression
The online intervention ‘Space from Depression’ is a seven-module online CBT-based intervention for depression, delivered on a Web 2.0 platform using media-rich interactive content. Programme content is delivered in a non-linear fashion. Each module takes roughly 1 hour to complete and it is recommended one module be completed per week. The structure and content of the programme modules follow evidence-based CBT principles. The treatment is comprised of established cognitive and behavioural components including self-monitoring, self-control desensitization, gradual stimulus control, thought recording, behavioural activation, cognitive restructuring, relaxation training and challenging core beliefs. Each module is structured to incorporate introductory quizzes, videos, informational content, interactive activities, as well as homework suggestions and summaries. In addition, personal stories and accounts from other users are incorporated into the presentation of the material. The intervention follows NICE guidelines for the treatment of depression and the intervention has been tested and proved efficacious (National Institute for Clinical Excellence, 2009; National Institute for Health and Clinical Excellence, 2006; D. Richards, Timulak, et al., 2015)
Space from Anxiety
Space from Anxiety is an eight-module online CBT-based intervention for Anxiety. The structure and content of the program modules follow established evidence-based principles of CBT for the treatment Anxiety. The treatment comprises cognitive, emotional, and behavioral components that include self-monitoring, relaxation training, cognitive restructuring, and worry outcome monitoring. The treatment is delivered on a Web 2.0 platform using media-rich interactive content. The getting started module for the core Anxiety programme introduces the user to the cycle of anxiety and the emotional, cognitive and behavioural aspects of anxiety. The goal of the intervention is to help people with anxiety as a primary disorder manages their thoughts, emotions and behaviours to help them alleviate their symptoms. The intervention follows NICE guidelines for the treatment of anxiety and the intervention has been tested and proved efficacious (National Institute for Clinical Excellence, 2009; National Institute for Health and Clinical Excellence, 2006; D. Richards, Timulak, et al., 2015).
Waiting list control group: Those in the waiting list group will be given access to the programme after an 8 week waiting period post randomisation. This group will receive assessments at baseline, and before they begin treatment after the 8 week waiting period.
