Study type
Description of intervention(s) / exposure
Our newly developed moderated on-line social therapy model (MOST) offers an ICT paradigm which has the potential to address important challenges in the engagement and treatment of young people recovering from early psychosis. We have pioneered and developed a new model for on-line behavioural interventions entitled “Moderated on-line social therapy” (MOST). The MOST model integrates on-line social networking with individually tailored interactive psychosocial interventions, with the involvement of expert mental health and peer moderators to ensure the effectiveness and safety of the intervention. MOST has been applied to a world-first program entitled “Horyzons” designed for the purpose of assisting young FEP patients in their recovery. Horyzons is a wesbite which has been designed as a supplement to traditional face-to-face biopsychosocial interventions for FEP, and has not been designed as a replacement for recommended treatments. The online intervention will be provided for a 4-week period. Participants will be asked to use Horyzons at their discretion.

Control group

Primary outcome [1] 286708 0
Acceptability of the system will be considered achieved if 10 of the 20 participants log on more than once per week across each of the four weeks during the 1-month of the pilot.

Follow-up assessment post-trial (1 month follow-up)
Primary outcome [2] 286709 0
The pilot will be considered to indicate safety of the Horyzons system if: (i) all participants report feeling adequately supported by moderators via the semi-structured interview, (ii) two or less participants experience relapse in psychosis during the 1 month of the pilot; (iii) no participants deliberately self harm during the course of the pilot; and (iii) if there are no unlawful entries into the Horyzons system.

Study design
Purpose of the study
Allocation to intervention
Non-randomised trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
After providing informed consent participants the RA will administer the SCID, BPRS and Calgary Depression Rating Scale. In a separate meeting the moderator will then orient participants to the Horyzons system. There will not be a control comparison intervention and all participants will have full access to their usual array of treatments at EPPIC and any treatments they are accessing elsewhere.
Participants will then be able to participate in Horzons at their convenience over a period of 1 month if they meet the inclusion and exclusion criteria.

Brief summary
In this study we will evaluate the acceptability, feasibility, safety and initial clinical benefits of an online intervention (HORYZONS) designed to maintain the benefits of early intervention services for psychosis over the long term.
We expect that HORYZONS will be well-received, safe and seen as a valuable treatment option by young people suffering from psychosis.
