Interventional
Description of intervention(s) / exposure
This study arm (also known as Program 1) involves guided care though an Outreach Service Navigator in Perth;
– A young person meets with the Outreach Service Navigator every 2 to 4 weeks (with or without family/ support person), in a safe space agreed to by the young person. This should begin within 2 weeks of randomisation.
– For the first 4 weeks, the Outreach Service Navigator meets with the youth (+/- family or support person) to build rapport. Once good rapport has been established, the Outreach Service Navigator and youth (+/- family or support person) will complete a new online health assessment tool that is currently not the standard tool used by General Practitioners (GPs). This online assessment is modelled on the Check Up GP app, which was co-designed with young people and is based on the HEEADSSS (Home environment, Education and employment, Eating, peer-related Activities, Drugs, Sexuality, Suicide and depression, Safety from injury and violence) preventive health framework for interviewing adolescents. Based on the results of the new online health assessment, the Outreach Service Navigator provides feedback and negotiates a plan for their unmet needs.
– A GP at Derbarl Yerrigan Health Service, an Aboriginal-community controlled health service in Perth, will develop a mental health care plan with the youth based on the new health check. They can refer the young person to other providers, support groups, support material as necessary.
– Each 2-4 weekly session with the youth is used to understand the level of support that is needed, organise and follow through with a mental health care plan, prioritise needs, facilitate access to wellbeing activities, track progress or reassess plans. This continues for up to 5 months. Each visit is likely to last from 30 minutes to 1 hour, or longer as needed. There is no minimum or maximum number of visits within the 5 month period.
– With the support and guidance of the service navigator, the type and level of support suitable for the young person's needs is determined on an individual basis by the young person.

At the 5 month data collection timepoint, after the participant has completed their allocated 5 months of care in the intervention arm, participants will be asked if they want to be interviewed about the trial as part of a process evaluation of the trial (assessing fidelity, acceptability, potential harms).

The Outreach Service Navigator supports the health and wellbeing needs of the young person as identified by the young person, which includes their mind, body and spirit. A young person may want help with job training or taking part in Aboriginal cultural events. The Service Navigator will have up to $500 to use for activities supporting the young person’s wellbeing.

Contact between an Outreach Service Navigator and a participant will primarily be in person, unless the youth advises of another preferred form of contact (e.g. text message, phone or video call). Typically a session occurs between one participant and the Service Navigator, however some group activities may be appropriate, such as cultural activities, where there may be a small group of participants working with one Service Navigator.

The Service Navigator is a specially-trained outreach health support worker (with a background in social work, psychology and/ or health sciences) and has experience working with Australian Aboriginal communities, especially with young people and in health care or social services settings, such as case management or service coordination.

Participant adherence will be captured during the scheduled discussions at the 5 and 10 month follow-up timepoints which will record changes in the participant’s clinical health management and/ or participation in wellbeing activities at any time during the 10 month follow-up period. Also, data relating to health/ wellbeing activities will be collected from the participant at each successive visit with the service navigator which will also be used to directly assess adherence to this study arm.

Comparator / control treatment
This study arm (also known as Program 2) involves standard care at Derbarl Yerrigan Health Service, an Aboriginal-community controlled health service in Perth. This arm focusses on standard management of an individual by a General Practitioner (GP) who can refer to other providers, support groups, support material as necessary. All Aboriginal and Torres Strait Islander people are eligible for a free, annual Indigenous-specific health check delivered using item 715 on the Medicare Benefits Schedule.
It is planned that;
– A young person should attend Derbarl Yerrigan Health Service within 2 weeks of randomisation to undergo the current standard Medicare 715 health assessment. This will be followed by usual care at Derbarl Yerrigan Health Service for up to 5 months.

At the 5 month data collection timepoint, after the participant has completed their allocated 5 months of care in the control arm, participants will be asked if they want to be interviewed about the trial as part of a process evaluation of the trial (assessing fidelity, acceptability, potential harms).

End of waitlist period for Control group participants: Following the 10 month follow-up outcome measures assessment, participants from the control arm may choose to receive the intervention treatment (without any further follow-up assessments). This includes direct contact with an Outreach Service Navigator to plan and achieve health and wellbeing goals, with funds to support these wellbeing activities for a period of up to 2 months. The service navigator will have up to $200 to use for activities supporting the wellbeing of these young people. There are no further follow-up outcome assessments for this group of participants.

Participant adherence to this study arm will be captured during the scheduled discussions at the 5 and 10 month follow-up timepoints which will record changes in the participant’s clinical health management and/ or participation in wellbeing activities at any time during the 10 month follow-up period.

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)
Randomisation occurs after completion of baseline assessments to ensure allocation concealment.
A statistician not directly involved in the trial recruitment and data collection will generate a computer-generated random allocation schedule, using permuted block sizes of random sizes to maintain balance in the number of participants allocated to each study arm. The randomisation schedule will be implemented via the randomisation module in the (Research Electronic Data Capture) REDCap database. The permuted block sizes will not be released until all participants have been recruited to ensure allocation concealment.
Participants will be individually randomised 1:1 to each study arm.

Efficacy
Statistical methods / analysis
A sample size of 246 participants (123 per study arm) will have 80% power at the 5% significance level (two-sided) to detect a difference of 0.35 standard deviations in mean K10 score at five months, after allowing for a correlation between the baseline and 5 months follow-up measures of 0.5 and 20% attrition rate.

According to population statistics, 30% of Aboriginal young people will score 22 or above on the K10 (high to very high psychological distress) and will be eligible for the study. This means, of the 6000 young people in the catchment, approximately 1800 youth could be eligible to undertake this study. To recruit the required number of individuals (n=246), approximately 14% of possibly eligible individuals in the community need to consent to participate.

Data from all randomised participants will be included in an intention-to-treat analyses.

Descriptive statistics will be used to compare young people’s characteristics between study arms. Generalised linear mixed effect models with fixed effects for service, study arm, time (baseline, 5 and 10 months), time by study arm interaction, and random intercepts for individuals will be used to test for differences in mean K10 scores between study arms at 5 months (primary outcome) and 10 months (secondary outcome). Estimated intervention effect will be reported as difference in means between study arms, with 95% confidence intervals and p-values. In sensitivity analyses, pre-specified baseline variables strongly associated with the outcome will also be considered for adjustment in the regression analysis. Similar regression analyses appropriate to the data type will be performed for the secondary outcomes. A detailed statistical analysis plan (SAP) will be developed and published prior to the conducting the statistical analysis. The SAP will detail the analysis of secondary outcomes and handling of missing responses, and other supplementary analyses, such as sub-group analyses, adherence-adjusted analyses, and sensitivity analyses to assess the robustness of the missing data assumption.

We will conduct a parallel process evaluation using mixed methods (qualitative and quantitative) to assess the intervention fidelity, explore its acceptability to Aboriginal health clinic workers, service navigators, young people and their parents/carers and document any potential harms.
