Plain English Summary
Background and study aims
CBT is an effective treatment for depression. Investment in the Improving Access to Psychological Therapies (IAPT) services has increased provision of brief, low intensity interventions in England. However, variation in the provision of high intensity CBT treatments remains. CBT-based computerised interventions (cCBT) were designed to make CBT available at low cost and have often been delivered as low intensity interventions with minimal or no practitioner support. However, engagement with cCBT is poor and, in the absence of support, effects are modest and short-term. Using technology and integrating online materials into therapy could increase efficiency, reduce costs, and widen access to therapy, whilst maintaining the long-term effectiveness of CBT delivered by high intensity therapists. We are developing a new intervention that will blend high intensity therapy with innovative use of technology to maintain effectiveness of face-to-face CBT. The aim of this study is to explore the views of service users, therapists and their clinical supervisors regarding the new online platform to ensure that the platform and CBT materials are acceptable, and to identify areas for improvement prior to a large study.
Who can participate?
The longitudinal study involves patients from GP practices in the Bristol region. Participants are 18 years or older and have a diagnosis of depression. The usability testing study involves patients recruited from psychology services in the Bristol area. Participants are 18 years or older and have received individual ‘high-intensity’ CBT for depression
What does the study involve?
Those invited to take part in the study will receive an information sheet detailing what the study will involve. In the longitudinal study, participants are asked some brief screening questions over the phone. If they meet the screening criteria, they are invited to a face-to-face appointment. This usually takes 60-90 minutes. Participants complete a consent form and some further questionnaires to see if the study will be suitable for them. Those who meet the criteria are then be offered up to nine, one-hour sessions of integrated CBT therapy, delivered by a therapist. The first session is face-to face, and subsequent sessions are delivered online (e.g. using instant messaging and/or voice communication). Participants are also asked to attend two interviews with a researcher so that they can share their views of the integrated therapy. In the usability testing study, potential participants are asked some questions over the telephone to check if the study is suitable for them. If it is, the participant is invited to attend a usability-testing session. Sessions are conducted individually and take 45-60 minutes. At the session, participants complete a consent form and a brief questionnaire. Participants are asked to look at the online CBT platform, and to test parts of the system (e.g. to complete a CBT worksheet online, read some of the online CBT resources, or test the online chat facility). At the end of the session, participants complete a questionnaire about their views on the platform, and how easy they found it to use.
What are the possible benefits and risks of participating?
In the longitudinal study, participants will have an opportunity to help inform the design of a new way of delivering CBT, and may find this interesting and rewarding. CBT is an effective treatment for depression. CBT can help participants develop ways of managing depression better, however this cannot be guaranteed. As this is a pilot study of a newly developed system of therapy, participants may experience minor technical issues with the online platform.
As with any talking therapy for depression, participants may find sessions emotionally challenging or upsetting. Our experienced therapists will be able to provide support within the sessions. The researchers will approach the screening appointment and interviews in a sensitive and supportive way. Although we do not anticipate that the sessions will be distressing, we will be able to contact a study clinician to offer support if necessary. In the usability testing study, participants will have an opportunity to help inform the design of a new way of delivering CBT, and may find this interesting and rewarding, however this cannot be guaranteed. As this is a pilot study of a newly developed system of therapy, participants may experience minor technical issues with the online platform. Our participants have an important role in helping us to identify any potential issues. The focus of the sessions will be on potential designs of the new therapy programme, rather than on participants’ personal experience of depression. The researchers will approach any discussions in a sensitive and supportive way.

Scientific title
The pilot evaluation of an online platform for delivering integrated high-intensity Cognitive Behavioural Therapy for depression
Acronym
INTERACT Phase 2
Study hypothesis
The aim of this study is to explore the views of service users, therapists and their clinical supervisors regarding the online platform we have developed, to ensure that the platform and CBT materials are acceptable, and to identify areas for improvement prior to a planned multi-centre randomised controlled trial.
We will conduct several design and evaluation activities in parallel to test the platform and revise its design based on user feedback:
1. A longitudinal evaluation with 12-16 primary care patients with depression. Patients will receive a full course of CBT delivered by a therapist through the platform.
2. Participatory design work with 2-3 therapists who are delivering the therapy within the study, and their clinical supervisor(s). They will also act as co-designers providing ongoing feedback.
3. Usability testing sessions with 9-12 people who received CBT in the past. These service-users will be recruited through local psychological services and will test changes to the platform arising from feedback.

Intervention
The study involves three strands of work running in parallel:
1. A longitudinal evaluation study with 12-16 primary care patients with depression, who will receive up to nine one-hour sessions of integrated Cognitive Behavioural Therapy delivered by a therapist through an online platform. Participants will be interviewed twice about their experience of the platform.
2. Participatory design work with 2-3 therapists delivering the therapy, and their clinical supervisor(s). These individuals will also act as co-designers of the platform and will provide ongoing feedback.
3. Usability testing sessions with 9-12 people who have received CBT therapy in the past, who will test specific changes to the platform arising from patient and therapist feedback.
Those invited to take part in the study will receive an information sheet detailing what the study will involve. In the longitudinal study, participants are asked some brief screening questions over the phone. If they meet the screening criteria, they are invited to a face-to-face appointment. This usually takes 60-90 minutes. Participants complete a consent form and some further questionnaires to see if the study will be suitable for them. Those who meet the criteria are then be offered up to nine, one-hour sessions of integrated CBT therapy, delivered by a therapist. The first session is face-to face, and subsequent sessions are delivered online (e.g. using instant messaging and/or voice communication). Participants are also asked to attend two interviews with a researcher so that they can share their views of the integrated therapy. In the usability testing study, potential participants are asked some questions over the telephone to check if the study is suitable for them. If it is, the participant is invited to attend a usability-testing session. Sessions are conducted individually and take 45-60 minutes. At the session, participantsl complete a consent form and a brief questionnaire.

Primary outcome measure
The purpose of this study is to gather initial qualitative feedback on the integrated CBT platform. Clinical outcomes are not evaluated as part of this study. Qualitative feedback on the integrated CBT platform will be assessed as detailed below.
1. Patients in the longitudinal study will be interviewed by a researcher after their second or third therapy session, and again once they have completed therapy. Those who withdraw from therapy or are discharged for non-attendance will also be interviewed. The purpose of the qualitative interviews is to gather initial views on the platform, its content, and the experience with this integrated approach to delivering CBT. The System Usability Scale (SUS) will also be used to guide discussion of the platform.
2. Therapists and clinical supervisors will provide ongoing feedback regarding their experience of the platform. Data collection methods will include design discussion sessions, individual interviews and focus groups, and use of the System Usability Scale (SUS).
3. The usability testing sessions will be task-oriented and analysed qualitatively and results summarised by the task they relate to. Types of issues will be counted to identify the most common and most serious ones. The SUS scores will be analysed and interpreted.
