Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Participants will receive their usual treatment and have access a moderated online social networking system, called Momentum. Momentum is an online intervention specifically designed to enhance social functioning in young people at ultra-high risk for psychosis (UHR). The Momentum system is based on the Moderated Online Social Therapy (MOST) platform developed by eOrygen. Momentum includes therapeutic activities and information about mental health, mindfulness, personal strengths, and other topics relevant for UHR young people, in the form of text and comics designed by eOrygen specifically for this study. Momentum also includes a social network where participants can communicate via posts and comments in a newsfeed and a problem-solving forum.

The online platform will be moderated by experienced mental health workers based at Orygen Youth Health. Trained peer workers with lived experience of mental ill-health will also provide support to participants through the Momentum social network.

Following randomisation, participants allocated to the Momentum intervention will complete an online orientation and follow-up phone call with the online moderator. Participants will access Momentum (including individualised therapist support) for 12 months. During this period, participants may access Momentum as often as they like, at any time, from any internet-enabled device.

Momentum integrates online personal therapist support (by clinical psychologists). Their role is to provide guidance, monitor participant’s clinical status and ensure the safety of the social network. Each therapist is assigned a caseload, which they follow for the duration of the trial. Moderators send each client tailored content suggestions weekly (e.g. a module or action) based on their needs and interests. Clients can rate the helpfulness of the suggestions, which moderators use to recommend subsequent content.

To promote engagement, retention of participants, and behavioural change, Momentum was developed following persuasive system design including primary task support (i.e., modularisation and personalisation of content), social support (i.e., fully integrated, purpose-built social network) and dialogue support (i.e., reward provided by therapists, peer-supporters and automated functions).

Users will be invited by moderators to meet other users at ‘Momentum Workshops’, which will occur which will occur approximately every 3-4 months. Meet-ups will consist of an interactive 1-hour session on ‘how to make Momentum work for you’ and will provide users with the opportunity to ask questions and give feedback on the system. Participants will be reimbursed for their time.

In the event of a clinically significant deterioration of psychotic symptoms, transition to psychosis, increased risk or a hospital admission, the clinical moderators in conjunction with the CI team will perform an assessment to determine the risks and benefits of a temporary withdrawal from Momentum. Based on this assessment, and in consultation with the young person, the team will determine whether the account is temporarily suspended, or level of access restricted (e.g., participant can access therapeutic content and support from moderators, and view content in the social network, but cannot post comments or participate in existing threads within the social network). Following suspensions or restrictions to a user’s account, the study coordinator or moderator will contact the young person at fortnightly intervals to ascertain whether the account is to be reactivated.

Behaviour
Comparator / control treatment
Participants in the control group will receive treatment as usual. Treatment as usual (TAU) consists of a range of treatment options delivered by treating teams at the Personal Assessment and Crisis Evaluation Clinic (at Orygen Youth Health) or headspace prior to discharge or, after discharge, generic medical or mental health services typically available to young people in the absence of enrolement in the study. These can include follow-up by a general practitioner, private psychiatrist, primary care youth mental health services, or adult mental health services which deliver multidisciplinary psychiatric care (including medical follow-up, case management and acute psychiatric care as appropriate).

EMA will be used to track patients’ appraisals of daily social interactions (i.e., social self-efficacy and social support), strengths use and momentary experiences of positive and negative affect. Brief surveys (approx. 2mins) will be sent to the participant’s smartphone once daily in the evening over the course of the study. EMA items have been drawn from previous research (Granholm et al., 2013). EMA will be administered via a smartphone application designed by CIs Alvarez, Gleeson and Koval. SEMA is available for iOS and Android-based smart phones, enables server-centred configuration (i.e. questionnaires, delivery times and data storage are configurable online) and stores data in real time in secure cloud storage, therefore minimizing loss of data.
Timepoint [12] 365883 0

Digital phenotype - represented by data collected via a passive sensing application downloaded on the participant’s smartphone. Participants who opt into this aspect of the study will have the option to select precisely which smartphone sensors they want to activate as well as duration and timing of sensing (by turning the application on and off). The following sensors will be used in this study:
a. Applications: Captures the applications being used on the smartphone;
b. Communication: Captures the number of incoming/outgoing calls and SMS messages, without recording the content of these calls or messages;
c. Locations: Captures user geolocation;
d. Screen usage: Captures when users lock/unlock their phones and use the screen, including time and duration of phone use. This sensor does not capture what is on the screen at any time;
e. Screen interaction: Captures when a user uses the keyboard, without recording what is typed. This sensor also captures when a user clicks and scrolls on their smartphone.
Timepoint [21] 365895 0
If participant's opt in to this, passive sensing will be continuously assessed for the duration of the study (12-months), however participant's have complete control over what data they would like to smartphone app to collect, and can opt out at anytime.
Secondary outcome [22] 365899 0

Therapeutic alliance will be assessed at baseline and 4, 8 and 12 months post baseline assessment. This measure will only be presented to those in the intervention group of the study.
Secondary outcome [25] 374577 0
Adverse events, defined as any untoward medical occurrence, and serious adverse events (SAEs), defined as any untoward medical occurrence that:
• Results in death;
• Is life-threatening (Life-threatening in the definition of serious refers to an event in which the participant was at risk of death at the time of the event, it does not refer to an event which hypothetically might have caused death if it were more severe)
• Requires inpatient hospitalisation or prolongation of existing hospitalisation;
• Results in persistent or significant disability/incapacity;
• Is a congenital anomaly/birth defect;
• Is an important medical event that although not immediately life-threatening or result in death or hospitalisation, based upon appropriate medical and scientific judgement, may jeopardise the participant and/or require intervention to prevent one of the outcomes listed above.

AEs and SAEs may be derived from a number of sources such as clinical results/reports, medical file reviews, spontaneous reporting or via non-leading questioning to the participant. The AE/SAE description, start and stop dates, intensity, causality and outcome will be recorded, as well as any actions taken.
Timepoint [25] 374577 0
Adverse events data will be collected throughout the duration of the study.

Sample size was determined by power analysis using G*Power 3. The primary outcome is difference in social functioning at 12 months. Our pilot study found a very large effect size improvement in social functioning from baseline to 2-months follow-up. This contrasts with follow-up and treatment studies in UHR patients, where social functioning has not improved over time (Fusar-Poli et al., 2013). Thus, we conservatively assume a medium treatment effect (Cohen's d=0.45), for which a total sample of 180 patients is required to achieve 85% power (alpha=0.05). The same applies for all continuous secondary outcome measures (e.g., depression, stress, quality of life). Regarding transition to psychosis, assuming a base-rate of 36% in the control group who transition to psychosis (Fusar-Poli et al., 2013) and a 54% reduction in rate of transition to psychosis in the treatment group (consistent with recent meta-analysis on the effectiveness of UHR interventions (van der Gaag et al., 2013)), a sample of 180 will ensure we have 81% power to detect a statistically significant difference in transition rates at p < .05. A total of 220 young people will be recruited, allowing for an 18% attrition rate following randomisation. This compares favourably with the attrition rates in the Momentum pilot (7%) and an ongoing 18-month follow-up RCT testing moderated online social therapy in young people with psychosis which recruited form OYHCP and headspace centres (15%).

Primary analyses will be undertaken on an intention-to-treat basis. Mixed-model repeated measures (MMRM) analyses will be used to compare change in social functioning between the two treatment groups over the 12-month follow-up. MMRM is the analysis of choice because assumptions of traditional data analysis methods (e.g., ANOVA, logistic regression) may be violated, such as the assumption of homogeneity of regression across time points (Brown & Prescott, 2015). MMRM will also be used to analyse change in the continuous secondary outcomes over 12 months. Group differences in risk of transition to psychosis will be tested using Fisher’s Exact Test, an alternative to the chi-square test more robust to small sample sizes (McDonald, 2014). Time to transition to psychosis will be assessed by survival analysis (using either proportional hazard or accelerated life-time models).

Mechanisms of action analyses will be conducted using a multilevel structural equation modelling (MSEM) framework to assess mediation. Specifically, person-specific slopes representing change over time in the proposed mechanism-of-action variables (self-efficacy, social support and subjective wellbeing) will be tested as mediators of the effect of treatment group (Momentum vs. TAU) on social functioning. MSEM will also be used to analyse passive sensing data collected by the AWARE mobile application, including the relationship between mobile data and study measures.

Economic evaluation will comprise a cost-consequences analysis whereby incremental costs of the intervention will be compared to the full spectrum of study outcomes. The evaluation will measure and value any change to the use of health care resources over the period of the study between the two treatment arms; and then compare any additional costs to the additional outcomes achieved. Standardised economic evaluation techniques including incremental analysis of mean differences and bootstrapping to determine confidence intervals will be used. If, as expected, the intervention is found to be effective, lifetime and population cost-effectiveness of the interventions will be determined using modelling techniques (Mihalopoulos, Vos, Pirkis, Smit, & Carter, 2010).
