Description of intervention(s) / exposure
Participants will be assessed to determine their eligibility in the study, part of this assessment period is to confirm a psychotic disorder diagnosis. All participants enrolled in the trial will undergo three assessments sessions: baseline (before Peer Tree), post-intervention/end of treatment (immediately after 6week intervention ends), and three months post intervention. After the baseline assessment, participants will be randomised to one of the following two arms:Peer Tree Smartphone Application or Treatment as usual.
Peer Tree Smartphone Application
Participants will use the Peer Tree smartphone application individually for approximately 5-10 minutes per day for 6 consecutive weeks. They will have the flexibility to use the app wherever and whenever they would like, with researchers being able to measure meta-data for adherence to using the smartphone application. The intervention involves short video clips in the form of animations, shared experience videos, actor videos, and expert videos displaying information about different social and emotional processing, and positive psychology principles. The content of the videos include a range of different themes from identifying strengths to expressing gratitude to findings wider meaning.
Participants rate their mood daily and are presented with one video per day. They answer questions about the videos to earn in-app rewards (e.g., tokens/badges to interact with the app). Challenges are provided throughout the intervention to assist participants in exercising the skills they have learnt and to maximise building relationships, these are not compulsory but are encouraged. Participants will also be able to access an online, moderated forum where they can discuss the different topics and challenges within the app. These will be moderated by clinicians, researchers, and peer moderators to ensure the safety of the app users.

Comparator / control treatment
Treatment as Usual
Participants in this group will undergo treatment as usual as the control condition for testing the Peer Tree Smartphone Application. Treatment as usual here refers to the participants' receiving their regular healthcare service as if they weren't enrolled in the research project. Once the three month post-intervention assessment is held, participants will have access to the content in the form of the previous version of the app, +Connect. +Connect does not include the interactive components and previous research has shown the app to be safe for consumers to use (manuscript under review).

Statistical methods / analysis
All data processing and analysis will occur either in the statistical package for the Social Sciences (SPSS), Mplus, or R data analysis software. Data manipulation will only occur if the data violates the statistical assumptions for the tests that we would be conducting. In this instance, the data will be transformed into a format that does not jeopardise the interpretability of the scores.
We envisage that any combination of the following will be used to assess the outcomes of the study: Mixed Model ANOVAs, Standard and Hierarchical Regression, Mediation and multiple mediation, latent trajectory modelling, t-tests and comparisons, and finally correlations.

Summary
Brief summary
The aim of the research project is to deliver and test an innovative digital smartphone intervention, Peer Tree, which is designed to reduce loneliness in young people with psychosis and other mental health conditions. The intervention is administered daily for 6 weeks.
Young people aged 16-25 years who report high levels of loneliness and have a diagnosis of a psychotic disorder or a different disorder that has psychotic features will be recruited. In accordance with a randomised control trial study design, after participants complete the baseline assessment, they will be randomised to either the treatment as usual or intervention group. Those in the waitlist group will complete treatment as usual but will be provided with the same content once they have completed the research project. This will be provided in the form of +Connect, the predecessor of Peer Tree that doesn’t not contain the forums.
Our research is expected to contribute to the development of personalised, modular mental health interventions that are cost-effective and efficient. There are currently no personalised, modular interventions available to address loneliness in young people.
