Implementation of Digital CBT for Insomnia in First Episode Psychosis

Study Overview
=================
Brief Summary
-----------------
This study uses mixed methods to investigate the implementation of digital cognitive behavioural therapy for insomnia (Sleepio) in a first episode of psychosis service (FEP). Interviews will be conducted with keyworker clinicians and service users to consider their expectations for digital sleep intervention. The rates of recruitment into the study, eligibility, completion of baseline measures, completion of the intervention sessions, attrition from the intervention and completion of follow up measures will be recorded. Interviews will be conducted with keyworker clinicians and service users to consider their experiences of digital sleep intervention. The primary outcome will be a logic model describing factors acting upon the implementation of Sleepio in this population. The investigators will provide signal data in relation to changes in insomnia severity, psychosis symptomatology, and general mental health.

Detailed Description
-----------------
First episode psychosis (FEP) services present a unique opportunity to effect change in outcomes in those affected by experiences of psychosis. Sleep disorder, particularly insomnia, is common in those affected by psychosis, including those experiencing a first episode and are associated with increased symptomatology. Mood and worry mediate the relationship between sleep and psychosis symptomatology and research suggests that improving sleep in this population can improve mental health symptomatology and longer term outcomes. Cognitive Behavioural Therapy is effective in treating insomnia (CBT-I). Pilot research suggests that insomnia is a tractable clinical target in psychosis. Furthermore, there is an appetite for therapeutic interventions for sleep in this population. Sleepio is an online Cognitive Behavioural Therapy for Insomnia (CBT-I) programme. Sleepio's components are those common to CBT-I interventions: i) Psychoeducation on sleep hygiene and processes; ii) cognitive components including restructuring, mindfulness, positive imagery, paradoxical intention training (trying to stay awake), and resolving thoughts about one's day; and iii) behavioural components including sleep restriction, stimulus control, and relaxation techniques. Sleepio is composed of six 20-minute sessions presented by an animated therapist (the Professor), which are unlocked weekly. Participants complete an initial assessment (please see 'Sleepio Onboarding Questions') and chose a treatment goal, which drives initial personalisation of the application. Participants book digital 'appointments' with the Professor and receive prompts to complete these 6 sessions, to enter sleep data and to complete the Sleep Condition Indicator. The Sleepio algorithm tailors ongoing intervention based on this sleep data and other data about participants' physical and mental health. Sleepio also provides access to online psychoeducation and a clinician-moderated user forum. This intervention has been shown to be as effective as 1-1 CBT-I in the general population. Sleepio has been used in mental health populations but has not yet been tested in people experiencing a first episode of psychosis. The study aims to use mixed methods to determine how digital CBT-I can be implemented in first episode psychosis services. These data will be integrated to build a logic model, based on the Medical Research Council (MRC) complex interventions framework. Keyworkers in Esteem FEP services will be approached to identify service users affected by sleep difficulties that may benefit from Sleepio. Service user participants will be recruited through their treatment as usual (TAU) with their Esteem keyworker (sleep monitoring is part of this). Where service users report sleep difficulties, keyworkers will offer an information leaflet about the study and referral into the research study or contact details for researchers (study email address). Keyworkers will record that service users have agreed to keyworkers providing their details to researchers and to being contacted by the researchers in their casefile. Those service users who wish to find out more about the study and meet eligibility criteria will be sent an easy-read Participant Information Sheet and Consent Form. They will be given the opportunity to ask questions and will be encouraged to speak to others about their potential participation (such as their keyworker). It will be made clear that in consenting to participate they are consenting to participate in sleep assessment, complete symptomatology measures pre- and post-intervention and use the Sleepio intervention. It will be made clear that participation does not affect their TAU. They will provide written consent if they wish to participate. Consenting service user study participants will receive access to Sleepio. They will register for the intervention with a researcher during the baseline symptomology measures assessment session. They will be given the option of additionally participating in semi-structured interviews prior to and after using the intervention, to talk about their expectations and experiences of Sleepio. Service user participants will not be randomized to treatment. All service user participants will be provided with access to Sleepio. Research will focus on developing a model for the implementation of this intervention. Keyworkers will be introduced to and supported in their role in referring service users to the study and monitoring use of Sleepio through presentations, psychosocial supervision, and reflection sessions. Keyworkers will be provided with an easy read information sheet which clarifies their role as clinicians (attending a session to reflect on their caseload and service user suitability for the study and providing suitable service users with information about the study) and potentially as research participants (in semi-structured interviews) via email and letter. They will be given the opportunity to ask questions and will be encouraged to speak to others about their potential interview participation (such as their colleagues). They will provide written consent if they wish to participate in semi-structured interviews, to talk about their expectations and experiences of Sleepio use in Esteem. Primary outcomes comprise implementation data and qualitative data concerning the perspectives of clinicians and service users, which inform the resulting logic model. Secondary outcome data comprises insomnia severity (Insomnia Severity Index), mental health symptomatology (Depression Anxiety and Stress Scales; The Revised Green et al., Paranoid Thoughts Scale (R-GPTS); Specific Psychotic Experiences Questionnaire (SPEQ) - Hallucinations Subscale) and worry about Covid19 (Fear of Covid19 Scale).

| Implementation data - completion of measures | Participant completion of measures assessment appointments and measures (ISI measure of insomnia severity, DASS-21 measure of mental wellbeing, R-GPTS measure of paranoia, SPEQ measure of hallucination, and Fear of Covid19). This outcome records whether or not these were completed by participants, whereas secondary outcomes 6-10 examine participant scores on these measures. | 8 months |

| Qualitative data | Service user and clinician expectations and experiences of digital CBT-I intervention | Across study timeline (8 months), across 12 weeks for service users (pre and post intervention) | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Insomnia severity | As measured by the Insomnia Severity Index (ISI). Possible scores range from 0 to 28 and higher scores indicate more severe insomnia. | 10 weeks | 
| Mental Wellbeing | As measured by the Depression, Anxiety and Stress Scales (DASS-21). Possible scores range from 0 to 126 and higher scores indicate more psychological distress. The maximum score on each subscale (depression, anxiety, stress) is 42. | 10 weeks | 
| Paranoia symptomatology | As measured by the Revised Green et al., Paranoid Thoughts Scale (R-GPTS). Possible scores range from 0 to 72 and higher scores indicate more severe paranoia. | 10 weeks | 
| Hallucination symptomatology | As measured by the Specific Psychotic Experiences Questionnaire (SPEQ) - Hallucinations subscale. Possible scores range from 0 to 45 and higher scores indicate more severe hallucinatory experience. | 10 weeks |
