Description of intervention(s) / exposure
The study treatment sequence involves three stages, which are referred to as steps. Each step follows on immediately from the previous step, without any break.

Step 1- Support and Problem Solving (SPS)

All trial participants receive Support and Problem Solving treatment in Step 1. This therapy will be administered by allied health professionals.

Support and Problem Solving therapy involves providing participants with emotional support and help with resolving their problems in day-to-day life. This treatment is administered to participants on a one-on-one basis, with each session lasting between 30-50 minutes. Step 1 involves attending between three and six sessions over the six-week period. The Week 4 and Week 6 visits also include an interview to assess their symptoms and mental state.

Depending on how they respond to the six-week period of treatment in Step 1, participants are randomly assigned to a new treatment arm at the end of Step 1 as detailed below:

Participants who improve with the Support and Problem Solving treatment they receive during Step 1, will be randomised to either continue receiving monthly SPS sessions for up to one year OR to simple monitoring at three-monthly intervals for up to one year.

Simple monitoring will consist of the research assistant carrying out a research assessment as well as the clinician making contact with the participant, either by phone or in person. The clinician will monitor the participant's mental state and risk and assess whether there has been any mental health deterioration which would indicate a need for change in clinical management (e.g. referral to a new service or need to reengage with headspace)

Participants who do not improve with the Support and Problem Solving treatment they receive during Step 1 will be randomised to continue receiving treatment in one of the two groups in Step 2 as outlined below.

Step 2- Support and Problem Solving (SPS) OR Cognitive Behavioural Case Management (CBCM). Both of these therapies will be administered by allied health professionals.

In Step 2, participants will receive either Support and Problem Solving OR Cognitive Behavioural Case Management for a period of 18 weeks. The treatment is provided on a one-on-one basis to participants, with the frequency of sessions depending on a combination of clinical need and preference of the participant. The sessions may occur weekly or fortnightly, and there will be at least six sessions provided during Step 2.

Cognitive Behavioural Case Management has a number of different elements including: strategies to help with stress management; therapy that targets thinking and behavioural patterns; practical assistance, as well as yoga and mindfulness.

Participants who improve with the treatment they receive in Step 2 will be randomised to receive EITHER monthly sessions of Support and Problem Solving for a further six months OR to simple monitoring at three-monthly intervals for a further six months.

Participants who do not improve with the treatment they receive in Step 2 will be randomised to one of two treatment groups in Step 3 as outlined below.

Step 3 Cognitive Behavioural Case Management plus antidepressant medication OR Cognitive Behavioural Case Management plus placebo medication.

Participants assigned to one of the two treatment groups in Step 3 will receive the corresponding treatment over a six-month period. The frequency of these sessions will depend on a combination of clinical judgement and the preferences of the participants, but may occur weekly-fortnightly. Both treatment groups will involve: regular Cognitive Behavioural Case Management sessions; regular review by a clinician, as well as the assigned medication. Participants will undergo regular review (fortnightly-monthly) with a psychiatrist who will monitor their response to the medication.

Depending on which group participants are randomised to, they may either receive antidepressant medication OR placebo medication. The medication is used alongside CBCM for the whole six-month period of Step 3.

The antidepressant medication used for Step 3 is a Selective Serotonin Reuptake Inhibitor called Fluoxetine. This oral medication will initially be prescribed at 20 mg/day, The dose of Fluoxetine will be titrated at 6 weeks from 20 mg to 40 mg daily (one to two capsules of matching placebo) if there is no response based on clinical judgment of the treating psychiatrist..

If a participant does not improve, or deteriorates by 12 weeks into Step 3, they will be given a choice to: continue with the treatment regime already assigned to them; increase the dosage of their medication, or start a new medication.

Upon their choosing, the medication at this stage may either be an antipsychotic medication (Quetiapine or Aripiprazole), OR omega-3 fatty acids ('fish oil'), taken in addition to the other treatment components of this step.

Quetiapine will be administered orally at a starting dose of 50 mg/day, and the dosage will be adjusted based on clinical judgment of the treating doctor.

Aripiprazole will be administered orally at a starting dose of 10 mg/day, and the dosage will be adjusted based on clinical judgement of the treating doctor.

Fish oil will be administered orally with the dosage being 2.8 g/day.

During Step 3 participants will be requested to return all unused medication and empty containers to the research assistants at their next visit. The research assistant will count and record the number of tablets and bottles returned. All participant returns will be returned to the dispensing clinical trials pharmacy for accountability purposes.

Compliance with medication will also be monitored using a mobile application developed by our group .This mobile phone application will consist of a system that prompts participants every evening to input their medication use (number of capsules taken) over the previous day.

A mobile phone message system will also be used to remind participants to take their medication (one message/day), which will assist in increasing compliance rates.

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
This is a Sequential Multiple Assignment Randomised Trial (SMART) of interventions (Support and Problem Solving, Cognitive Behaviour Case Management, antidepressant medication) for young people at "ultra high risk" of psychosis. 340 young people who meet study criteria will be randomised from five Melbourne clinics.

The randomisation process will be protected so that the treatment that the participants are to be allocated to will not be known before the participant is entered into Steps 2 and 3. The process of allocation will occur via a predetermined randomisation schedule, and research personnel will have no way of predicting which group the participant will be allocated to.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Participant eligibility will be established before randomisation at Step 2 and 3. The randomisation schedule will be generated by a statistician independent of the study team.
Computer generated random numbers will be used to determine the randomisation schedules for Step 2 and 3. A participant identification (ID) number will be allocated to each participant who provides informed consent, so that participants can be identified without making assumptions about their subsequent eligibility for the study. If a participant fails screening and is not randomised, or discontinues from the trial, the participant ID number will not be reused.

Other design features
This is a sequential multiple assignment randomized trial (SMART). Non-responders graduate to the next stage of intervention, while responders are offered entry to a maintenance/relapse prevention arm in which modest psychosocial care is compared in a randomised design with monitoring alone throughout the first 12 months of the study. A “fast fail” feature is included in step 3 if the participant deteriorates or fails to show improvement. This consists of dose enhancement and entry to a personal choice/shared decision-making treatment option.

Efficacy
Statistical methods / analysis
The STEP study was powered on the primary aim of comparing the 6-month functional outcome between the two treatment groups in Step 2 (it is standard for SMART trials to be powered on a single stage or aspect of a multi-staged design). Approximately 5000 young people per annum will be attending headspace centres from 2014. Recent data indicates that approximately 38% of young people seen at headspace meet UHR criteria, which means that approximately 2000 patients per annum will be eligible for the study. A two-year recruitment period means that 340 participants would need to be recruited from a pool of 4000 patients (8.5%). This recruitment rate is highly realistic given that recruitment rates to our previous UHR intervention trials have been approximately 30% of eligible patients. Upon assessment of STEP participant flow and response in November 2017, 18 months into the recruitment period, the non-response rate at the end of Step 1 was approximately 87% with a drop-out rate of 17% in step 1. For step 2, the non-response rate was approximately 85% with a drop-out rate of 30%. Assuming that the response and drop-out rates remain consistent and that we reach an entry sample size of 340, we expect a step 2 sample size of 245 with which we will be able to detect a fairly small effect size of 0.21 with a power of 80% and a significance level of 0.05 by the end of step 2. Based on the drop-out rate and non-response rate of step 2 indicated above, we expect to obtain n=145 in Step 3, which will be sufficient to detect a clinically important medium effect size of 0.25 for the secondary aim with a power of 80% and significance level of 0.05.
