A deep learning probability model to deliver feedback-informed, internet-delivered psychotherapy for depression and anxiety

INTERVENTION: All PWPs who give clinical support to clients in IAPT at NHS Berkshire will be eligible to participate in the research. We will seek to recruit all current PWPs to the study and the ones randomly assigned to the DLM condition will use the feedback‐informed outcome probability across all their clients during a 6‐month period. PWPs will attend a short information session and then will be emailed an information sheet. PWPs will be asked to indicate consent online through Qualtrics. The ones who consent to the study will be randomized to DLM or control groups and will complete questionnaires (control group received questionnaires at baseline and 12 weeks, and DLM group received questionnaires at baseline, 4 weeks, and 12 weeks). Explicit consent will not be sought from each client as the research falls within the rubric of service development and evaluation. PWPs will be randomized between those who will have access to the DLM probabilities and those will not. Randomisation will be based on experience using SilverCloud, i.e. how many clients the PWP has seen on SilverCloud prior to the start of the trial. Based on experience, there will be 2 categories of supporters: novices (1 to 40 clients) and experienced (over 40 clients on SCH). There will be equal proportions of novice and experienced PWPs in both DLM and control conditions. Qualtrics will be used to randomly assign supporters to the intervention or control groups after consenting to the study. The DLM tool will be on for all clients of the PWPs in the intervention arm. CONDITION: Initial performance and overall acceptability of a DLM for feedback‐informed outcome probability in iCBT for depression and anxiety. ; Mental and Behavioural Disorders PRIMARY OUTCOME: Depressive and anxiety symptoms will be measured with PHQ‐9 and GAD‐7. As part of their routine treatment, clients complete these scales every 7 to 10 days throughout the duration of their treatment. SECONDARY OUTCOME: PWPs acceptance of the tool, as well as the impact of the tool on deliberate practice will be measured qualitatively through survey questions. PWPs will complete surveys at baseline, 4 weeks, and 12 weeks from the start of the study. INCLUSION CRITERIA: All PWPs who give clinical support to clients in IAPT at NHS Berkshire will be eligible to participate in the research
