Description of intervention(s) / exposure
The Groups 4 Health Program:
Groups 4 Health (G4H) is a theory-driven, evidence-based, manualized psycho-therapeutic intervention that targets social isolation. G4H is designed to give young people the knowledge and skills needed to build and maintain their social world. G4H was developed using the latest science in social and clinical psychology, which suggests that group-based relationships are especially important for well-being.

The intervention comprises 5 x 1.5 hour face-to-face group facilitated sessions, run weekly in the first month with the final module 5 delivered 1 month later. Modules 1-4 have associated homework after each session which takes about 30 minutes. Facilitators are Clinical and Health Psychology postgraduate students who receive training and weekly supervision to deliver the program.

Module content is summarised below.

Module 1: Schooling. Raises awareness of the beneficial effects that social group memberships have for health. It highlights the costs of ignoring the social dimensions of health and points out that failure to use all the social resources at our disposal generally leads to sub-optimal health outcomes. The module also makes the point that it is within people’s power to counter these effects by learning how best to develop, maintain and harness group-based resources.

Module 2: Scoping. Focuses on the range of group-based resources that people have, or ideally should have at their disposal, to optimize health. This module engages participants in the process of social identity mapping (Cruwys, Steffens, Haslam, et al., 2015). This tool was developed to explore respondents’ social identities, in order to assess their current social functioning and develop a sense of how they would ideally like to function in the future, identifying current group memberships and any gaps in group networks.

Module 3: Sourcing. Targets development of skills needed to identify and strengthen existing valued social identities with a view to optimizing and sustaining these in the longer term. It also raises awareness of solutions to barriers to making the most of existing groups.
Module 4: Scaffolding. Uses the G4H group as a model for establishing and embedding new social group connections whilst at the same time exploring strategies to identify which connections to develop and enact through a social plan of action. The goal is to trial these social plans between this and the final module, which takes place at least one month later.

Module 5: Sustaining: Is a booster session held one month later that aims to troubleshoot any difficulties that have arisen in the course of implementing these social plans. It also revisits social identity maps, created in Module 2, to see how they have developed in the course of the program. The social foundations that have been identified and developed in the preceding four modules are also reviewed with a view to encouraging their long-term maintenance.

In addition to the facilitator manual, the program is supported by a client workbook. This contains a summarized version of the facilitator’s manual highlighting the main activities and learning points for each session, with sufficient space to complete activities (both within the sessions and as homework) and document any relevant notes and plans to achieve particular goals.

Treatment fidelity is assessed by weekly supervision from a registered psychologist, and a brief questionnaire completed by facilitators at the end of each session delivered. This requires facilitators to tick off session activities covered, rate alliance and rapport between participants and with facilitator, indicate the length of session, and rate session satisfaction and ease of delivery.

Behaviour
Comparator / control treatment
Group CBT:
The comparison treatment used in this trial is Cognitive Behaviour Therapy (CBT), which is the psychological intervention with the strongest evidence base to date. CBT involves participants engaging in an active, collaborative discussion about how their thoughts, feelings, and action are linked. Specific strategies to challenge unhelpful thinking and modify unhelpful behaviours are taught and practised. Previous trials and meta-analyses have found CBT to be effective in reducing a wide range of mental illness symptoms, including depression which will be the focus in this trial. A manualised, 5 session form of CBT will be used that has been found to be effective in previous published trials (Stice, Rohde, Seeley & Gau, 2008).

Other design features
This is a non-inferiority trial. We hypothesise that both interventions will be effective in reducing depression symptoms, but that G4H will be superior in reducing the social isolation that causes depression. This trial will therefore test the capacity for G4H to function not only as a treatment, but also as relapse prevention for young people at risk of depression recurrence.

Efficacy
Statistical methods / analysis
Power calculations for a non-inferiority trial were conducted, using effect sizes and retention rates from our published pilot. Specifically, to have 0.80 power to detect a clinically significant difference (3 points on the DASS-21 depression subscale, using expected standard deviations for an adolescent population) with an alpha level of 0.05, N = 29 people per condition would need to be retained for one year follow up. Assuming 50% eligibility and 60% survival rates, which are consistent with our pilot data, we anticipate that screening 400 people for eligibility will lead to retention of approximately N=60 people per condition at follow-up.

Analysis strategy:
Separate repeated measures ANOVA to assess the effect of intervention on primary and secondary outcomes, both with intention-to treat (where outcome data is estimated using carry forward of last available observations) and per protocol analyses (only including participants who met eligibility criteria, were randomly assigned, and completed the intervention according to the protocol, and had both baseline and follow-up data).

Summary
Brief summary
Social isolation is a major cause of depression onset and relapse in young people. Yet this is not directly targeted in current treatments for depression. To address this disconnect, our project will conduct a randomised controlled trial to assess the efficacy of a novel intervention that targets social isolation in young people with depression (called Groups 4 Health). Our trial will compare the effectiveness of Groups 4 Health to another effective treatment, group Cognitive Behaviour Therapy (CBT), at program completion and one-year follow up. Participants will be 200 young people aged 15-25, recruited from public and private mental health services in the Southeast Queensland region. We expect that both interventions will be effective in reducing depression symptoms, but that Groups 4 Health will be superior in reducing the social isolation that causes depression. This trial will test the capacity for Groups 4 Health to function not only as a treatment, but also as relapse prevention for young people at risk of depression recurrence. Therefore, the benefits of Groups 4 Health are expected to be particularly apparent by the one-year follow-up. This program offers a new approach to treatment and relapse prevention of the leading cause of disability among young people in Australia.
