Description of intervention(s) / exposure
Approximately 96 to 120 adults aged 40 and over from Arabic-, Vietnamese-, Greek-, and Hindi-speaking communities in Australia will participate in a dementia prevention intervention through an educational program, the “MindCare program”, delivered by community peer educators at the sites of five partner organisations. The program is designed to improve self-efficacy, health literacy, and knowledge of dementia risk reduction among community members from culturally and linguistically diverse (CALD) backgrounds. It has been specifically tailored for Australians from Arabic-, Vietnamese-, Greek-, and Hindi-speaking groups.
The MindCare program was developed through a comprehensive co-design process involving members of the target communities, clinicians, and service providers. The co-production process occurred in three following stages:
The first stage included six co-production workshops conducted in English to develop a multicultural base program. Each workshop lasted approximately two hours and involved 8-12 participants, including consumers and service providers from the Arabic-, Vietnamese-, Greek-, and Hindi-speaking communities. Participants reviewed dementia risk reduction materials and provided feedback on the content, format, and cultural relevance, which was integrated iteratively.
The second stage consisted of seven cultural adaptation workshops and five individual sessions, where bilingual research assistants facilitated sessions in the respective languages to tailor the program for each community. Each group session lasted approximately two hours and included 2-10 participants who refined the materials based on cultural and linguistic needs.
Following cultural adaptation workshops, the program was circulated to all participants for memberchecking and feedback. Further to this the MindCare program is currently undergoing user testing with up to 15 participants from Hindi, Vietnamese, Arabic and Greek speaking backgrounds as well as sessions in English, User testing sessions (2-3 hours) assess usability, cultural relevance, and engagement to ensure the program is culturally and linguistically appropriate and ready for the trial.

The intervention using the MindCare program, as finalised after the above testing with community members, is a 3-hour workshop delivered in person in community settings by bilingual peer educators who are bilingual members of the CALD communities and engaged by the project's partner organisations (Ethnic Communities’ Council of Victoria
Multicultural Aged Care, South Western Sydney Local Health District, SydWest Multicultural Services, Umbrella Multicultural Community Care). The workshops provide a brief introduction to dementia, but the main focus is to educate participants about the modifiable lifestyle risk factors that can reduce the risk of developing dementia, and that people can potentially address through simple everyday actions (e.g. getting a hearing check, or making sure to get your cholesterol checked at the GP from time to time).
The program includes components to encourage engagement such as discussions, culturally relevant examples, in-language multimedia materials (such as the short films and animations developed by the MovingPictures research team, available at https://www.movingpictures.org.au/), and goal-setting activities where participants set personal health goals related to dementia risk reduction.
Participants in the intervention arm will be asked to attend a session provided in their language and complete surveys at three time points: baseline (before the intervention), immediately post-intervention, and six-week post-intervention. The surveys aim to assess changes in self-efficacy, knowledge, and health literacy, using questionnaires adapted from the General Self-Efficacy Scale (GSE) [1], the Knowledge of Dementia Risk Reduction (KoDeRR) survey (developed by the University of Tasmania’s Dementia Research and Education Centre) [2], and the Health Literacy Survey European Questionnaire (HLS-EU-Q16) [3]. These surveys will be built on REDCap or Qualtrics and tested by the research team before the intervention.
Community peer educators will be trained by the Lead Investigator and bilingual research assistants on how to deliver the education sessions to community members taking part in the trial. The training will consist of three weekly sessions, each lasting two hours, and will be completed at least two weeks before the intervention begins. Within one week before each educational session (the intervention), a member of the research team, in collaboration with community peer educators, will collect participant responses to the baseline survey (timepoint 1). The training to peer educators will ensure they are equipped to assist in recruiting participants, facilitate the collection of baseline survey responses, and deliver the program in their respective languages. During the workshops, peer educators will also support participants in setting personal health goals, monitor participant progress and provide ongoing support after the workshops, contributing to the program’s overall evaluation.
At the education session, each participant will receive a booklet specifically designed for this study, containing presentation slides of the MindCare program, presenter’s notes, materials for goal setting, and a tip sheet in the form of a fridge magnet as a reminder of dementia prevention tips. The intervention will be monitored through the attendance of two research team members (either in person or online). Participants will be encouraged to take home the materials and respond to the immediate post-intervention survey (timepoint 2) within two days of attending the session.
The evaluation of changes in self-efficacy, knowledge, and health literacy will be conducted approximately six weeks after the intervention (timepoint 3). A member of the research team will contact participants and send them the 6-week follow-up survey to collect quantitative data about knowledge retention, lifestyle changes related to dementia risk reduction, and overall progress on their health goals.
The study will aim to recruit a similar number of participants (approximately 24~30) from each community to ensure equitable representation across the four groups. By delivering the program in participants’ native languages and engaging community peer educators, the MindCare program seeks to ensure cultural relevance and accessibility while promoting dementia risk reduction within CALD communities.

Comparator / control treatment
The control groups will also include approximately 96 ~ 120 adults aged 40 and over from Arabic-, Vietnamese-, Greek-, and Hindi-speaking communities in Australia who do not undertake the MindCare program but will attend a 90-minute session on general healthy ageing, based on WHO Healthy Ageing guidelines. The deliveries of the healthy ageing program to the control groups will also be conducted by community peer educators. While the same set of surveys will be administered at three-time points - baseline, immediately post-session, and six weeks post-session - to collect quantitative data, the control group will not engage in interactive discussions or goal-setting activities related to dementia risk reduction.

Efficacy
Statistical methods / analysis
Group differences at baseline will be compared using mixed linear or logit models incorporating a random effect of site/cluster. The primary outcome analysis will be undertaken on an intention to treat basis, including all participants randomised, regardless of intervention received. The primary outcome will be analysed using the GSE in a mixed-effects model repeated-measures analysis, conducted in Stata 16. Sites will be included in the analyses as a random effect to evaluate and accommodate clustering effects. Comparable methods will be used for the secondary outcomes.
Additional sub-analyses will be undertaken to examine the effects from covariates such as basic demographics such as age (years), sex (male/female), ethnicity, location, educational and economic attainments, country of birth, English proficiency). Where relevant, we will also examine effects of other covariates such as native language proficiency, years lived in Australia, and visa on entry to Australia (e.g. to distinguish economic from humanitarian migrants).

Summary
Brief summary
This project aims to test and implement the MindCare education program, an intervention designed to improve self-efficacy, health literacy, and dementia risk reduction knowledge among community members from Arabic-, Vietnamese-, Greek-, and Hindi-speaking backgrounds aged 40 and over. The program was developed using co-design methods with input from CALD communities and service providers, and is delivered by bilingual peer educators through community-based workshops. The trial will assess the impact of the MindCare program through a randomised controlled trial, comparing outcomes between the intervention group and a control group that receives basic healthy ageing advice. Key objectives include improving participants' confidence in managing their health, increasing knowledge of dementia prevention, and evaluating the program’s acceptability and effectiveness within community settings. The trial will also examine the influence of cultural and linguistic factors on the program’s success in promoting healthier lifestyles for dementia prevention.

The study hypothesis is that participants who receive the MindCare intervention will show improvements in several key areas compared to those in the control group. Specifically, it is expected that the intervention group will demonstrate increased knowledge of dementia risk reduction, improved health literacy, enhanced self-efficacy, and greater changes in health-related behaviours and lifestyle for dementia prevention. These improvements will be compared to the outcomes of the control group, which will only receive basic healthy ageing advice.
