Description of intervention(s) / exposure
Connect Local -– a codesigned social prescribing program
This is a non-randomised trial where all eligible individuals living in the Local Government Area (LGA) of Glen Eira City Council who are participating in Connect Local will be invited to participate in the evaluation.
The Connect Local service will be delivered to the individual by the community connector in the following manner, with the involvement in the Connect Local program being over three months – although this will vary, based on the individual needs and preferences - while the evaluation will be following participants over 12 months:
1. Spend at least an hour in a face to face appointment with participants to:
a. Identify what matters to them;
b. Work together on generating goals to address a social need, and a develop a plan to achieve these goals through linking them to activities and/or programs being offered in the Local Government Area (LGA) of Glen Eira City Council;
c. Some examples of activities include: walking group, gardening group, crochet club, book club. These can be offered at the local community house or the local library.
2. Have a second face to face session of approximately an hour the following week, where:
a. The individual will be supported to access these activities/programs through accessing local resources;
3. Have a follow up appointment by phone of approximately 20 minutes within a week of accessing the activity/program to assess whether the activities/programs have met their needs and they will continue to engage;
a. Should there be any issues, the Community Connector may either engage with the program/activity provider to address them, or work with the individual to develop a new goal, plan and access new activity/program.
4. Have follow up phone calls of approximately 20 minutes after 2-3 weeks to ascertain progress;
a. Should the individual have issues or need more engagement in additional activities/programs, face to face appointments to ascertain their needs and linking to additional activities/programs will occur.
5. Continue with follow up calls of approximately 20 minutes duration every 2-4 weeks, until 3 months where the final call outlines the Community Connector has fulfilled their role and the individual can continue engaging in the activity/program.
Community Connectors:
These are individuals with a tertiary qualification in health or social care related field. They are selected specifically for their high emotional intelligence, including the ability to build rapport with individuals, listen non-judgementally and work with individuals to identify what matters to them. A community development background is highly desirable. Prior to engaging participants, all Community Connectors are provided with a comprehensive orientation guide about the program and the activities involved and undergo training over 2 weeks prior to seeing community members, in social prescribing (WHO developed online training program of 2hr duration, wellness and reablement (including identifying ‘what matters to you’ and goal setting) of 4 hours duration, Cultural Diversity webinars and training modules of 2 hours duration, mental health first aid of 1 hour duration and trauma informed care of 2 hours duration.
There are weekly meetings with the manager and community connectors to discuss the activities the community connectors have undertaken, debrief and plan the next week.
Strategies to monitor adherence of the intervention:
The program has developed documentation tools to capture information regarding engagement of participants through the program, including when participants are contacted, duration, activities and outcomes as part of the care delivery of the program.
The codesign process to develop Connect Local:
Codesign involved occurred between October 2021- December 2022 online and in local venues, engaged six community members (six 2hr sessions), nine local social service stakeholders (three 2hr sessions) and eight local healthcare service stakeholders (six 1.5hr sessions) living and/or working locally. Awareness of the program, recruitment of program participants, delivering the program and how the program would measure success were articulated and tested.

Comparator / control treatment
The comparator group will not have any prescribed intervention additional to usual care, but live outside the target Local Government Area.

In general, usual care consists of an ad hoc approach by some healthcare providers regarding asking individuals about their social connection needs and raising potential non-medical interventions as an avenue to address them, and leaving it to the individuals to pursue. Information about social connection activities is available online and at various community centres, however individuals need to seek the information out to find out about them.

Sample size calculation:
The primary outcome is a reduction in loneliness at 3 months for participants receiving the Connect Local program, when compared to the comparator group. A program conducting similar activities found a statistically significant reduction in mean UCLA-3 scores of 0.85, with a medium effect size of 0.37 (Brown, 2018). Using this effect size and aiming for 0.9 power at 0.05 alpha we need 76 participants in each group: the intervention and matched comparator.

Allowing for 15% loss to follow-up at 3 months we have inflated the sample size to 88 per arm, for a total of 176 participants in both the intervention and comparator groups.

Statistical analysis
Outcome 1: Intervention evaluation - program effectiveness.
Quantitative data analysis
For all quantitative, repeated, continuous individual level variables (loneliness, social isolation, social anxiety, depressive symptoms, wellbeing, quality of life) the main research question will be whether the study intervention is effective at improving the outcome of interest compared with usual care . Modelling these data will focus on fitting linear mixed models using different covariance matrices such as: unstructured, an exchangeable-changeable and AR level-1 residual matrices, where the mean structure of all fitted models include a term for intervention group and a term for time and an interaction term for time and intervention. Non-linear outcomes will be fitted using Generalised Estimating Equations (GEE) analysis which requires that the missingness mechanism is Missing Completely At Random (MCAR). Alternatively, polynomials and/or piecewise linear functions will be utilised for modelling outcomes with non-linear growth trajectories if responses are Missing At Random (MAR).
For quantitative, binary or dichotomous individual level outcomes (scales that have cut-off scores: loneliness (UCLA-3), social anxiety, depressive symptoms) additional analysis will be undertaken addressing the research question: do the interventions differ in their effectiveness , such that individuals in the intervention group experience a greater improvement in their probability of achieving the desired outcome comparted to those receiving usu al care . Generalized linear mixed models for dichotomous outcomes will be used as well as GEE. The typology of missing data will be investigated to make sure that the assumptions of the adopted statistical technique are not violated.
To identify the model that fits the data best, the Akaike information criterion (AIC) and Bayesian information criterion (BIC) will be used to compare non-nested models and the log-likelihood ratio test will be used to compare nested models. A model with a smaller AIC or BIC will be considered to fit the data best.
All quantitative community and system level variables, as well as the goal attainment will be analysed descriptively. Descriptive statistics will be presented as proportions, means (standard deviations) or, for variables that did not conform to a normal or log-normal distribution, medians (interquartile range).

Statistical analysis will be performed using STATA V.15.0 (STATA Corp LP., College Station, Texas, USA). We will use a Type I error rate of 5% to indicate statistical significance, with 95% confidence intervals (CI).

Missing Data: General and generalised linear mixed models use maximum likelihood estimation which produces robust/unbiased estimates as they make implicit corrections for missing data, hence they are likely to retain more power if participants are lost to follow-up than traditional repeated-measures ANOVA/ANCOVA approaches which use “complete-case-analysis” approach that only includes cases with no missing data in the analysis.
If more than 5% of the outcome data are missing, a sensitivity analysis will be conducted comparing fitted models in terms of estimates and corresponding standard errors using maximum likelihood estimation with and without considering different imputation techniques.

Qualitative Data Analysis
For all qualitative individual, community and system level variables, interviews with participants will be audio-recorded, transcribed and then analysed utilising thematic analysis. Thematic analysis involves finding repeated patterns of meaning within qualitative data (Braun & Clarke, 2006) and will be facilitated with the use of qualitative management and analysis software such as NVivo (Q.S.R. International, 2016). In addition, an interview summary will be created for each interview and circulated to the research team, facilitating the team’s ongoing knowledge of the data being collected. An inductive approach will be used within the project, which allows for themes and findings to emerge from the data, grounding the findings in the perspectives and experiences of participants.

Mixed method approach: Triangulation will be used to combine the qualitative and quantitative data using a deductive-simultaneous design (Schoonenboom & Johnson, 2017) where the core component is quantitative, and the supplemental component is qualitative.

Outcome 2: Health Economic Evaluation - program cost effectiveness
The research team will identify and categorise the stakeholders, and the outcomes most relevant for each, and then apply the following tools of SROI: consideration of deadweight, displacement, attribution and drop off. We will do this through discussion between team members undertaking evaluation and program implementation in relation to each of the outcomes considered in the SROI.
Calculating the SROI:
The calculation of the SROI will consider the total value of the inputs in the program. The discounted, monetised value of benefits and outcomes will be divided by total investment (inputs) to estimate the SROI ratio.

Outcome 3: Implementation - Process evaluation
1. Reach and adoption: This will include quantitative data that will be reported descriptively, using frequencies and proportions .
2. Feasibility., Acceptability and Appropriateness: This will include quantitative data that will be reported descriptively, using frequencies and proportions. Qualitative data will be analysed thematically using an inductive approach, as described above , to ascertain themes around feasibility, acceptably and appropriateness of the program. Process data regarding organisational support systems and processes will also be reviewed by the research team, discussed as a group, considering the content in light of the qualitative data analysis results to form synthesised outcomes. This information will be reported narratively.
3. Fidelity and sustainability Interview qualitative data will be analysed deductively, to ascertain whether program components were delivered as planned. Further, information on organisational support systems and process will be reviewed by the research team to consider the sustainability of the program. This information will be reported narratively.
Mixed methods approach: Expansion method, using simultaneous design where the core component is quantitative and the supplemental component is qualitative (Schoonenboom & Johnson, 2017).
