Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Both Group 1 (Intergenerational Program + Positive Mental Health) and Group 2 (Intergenerational Program) consist of 20 weeks of intergenerational sessions, at a dosage of 1x 2-hour session per week. In both groups, the intervention is delivered in a group format (bringing approximately 10 pre-school aged children and 10 older adults together), and within community pre-schools or associated spaces (e.g., connected halls).

The sessions of the 20-week program (hereafter: 'Intergenerational Practice Program' / IPP), in both Group 1 and Group 2, are based on the Early Years Learning Framework and allow adaptation to child and adult interests. Activities will require older adult and child participation, and can be adapted to suit physical limitations but also to stretch those who are more able. To standardise, each week is designed around meeting target “skills” (involving things like physical and cognitive activity), whilst maintaining focus on intergenerational collaboration. The IPP delivered to participants of the overarching INTEGRITY Trial is designed to be flexible, with no two weeks of activities the same. GenWell-BRAVE builds upon this by prescribing activities which target positive mental health (e.g., mindfulness, gratitude, savouring) within the IPP received by Group 1, and proscribing these activities for Group 2, to explore how they influence engagement and outcomes.

IPP sessions in both Groups will be facilitated under the purview of the INTEGRITY Trial. They are led by an early childhood educator who, at minimum, holds a Certificate 3 in Early Childhood Education. This educator will be trained on the protocol and IPP. A second early childhood educator employed at the preschool associated with a given cluster will also be present to ensure child wellbeing/safety, support the children in navigating the IPP, and assist in the flow of sessions. This educator must also have up-to-date early childhood accreditation. A maximum of two researchers or trained volunteers will also be present at each session to advise (e.g., protocol adherence), help set up/clear away, collect observation data, and/or monitor for safety (e.g., trip hazards).

Fidelity of implementation will be evaluated through recording of each session using a bespoke Target Domain & Dosage Checklist.

Participants in this trial will be drawn from clusters of the INTEGRITY Trial (ACTRN12623000127606 )which have been randomised to waitlist-control (i.e., participants currently providing data over a neutral window, but not during their receipt of the IPP). Clusters for GenWell-BRAVE will be a convenience sample of these sites, based on those who have IPPs being delivered during the GenWell-BRAVE timeframe (or until sample size is met). Additional consent will be sought from participants at these clusters for GenWell-BRAVE.

Prevention
Comparator / control treatment
The comparator in this study is Group 2. Group 2 is an Active Control in the context of this sub-study, and corresponds to the IPP typically delivered in the INTEGRITY Trial. Group 2 is identical in nature to Group 1 (described above), except activities targeting Positive Mental Health (e.g., mindfulness, gratitude, savouring) are proscribed.

Purpose of the study
Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Allocation will be concealed from participants and researchers involved in adjudicating the outcomes of the trial. Randomisation will be conducted centrally by computer, and at the cluster level. It will be concealed from relevant researchers using digitised methods (e.g., password protected documents).
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Cluster randomisation using a randomisation table created by computer software. Clusters will be randomised for GenWell-BRAVE in temporal order of their follow-up testing date for the INTEGRITY Trial (i.e., prior to recruitment for GenWellBRAVE commencing at each cluster).

Efficacy
Statistical methods / analysis
GenWell-BRAVE intends to randomise 4 community-preschool clusters, with a target sample size of N = 80 [Adults, n = 40; Children, n = 40]. This target is based on a convenience sample of available INTEGRITY waitlist-control clusters, and feasible IPP enrolment rates. The target number of participants at each site (10 adults, 10 children), is determined by pre-school ratio requirements and best-practice guidelines for intergenerational practice which are indicative of a maximum 2:1 (child to adult) ratio for optimal program functioning. If recruitment uptake is low, GenWell-BRAVE maintains the option to adopt and randomise additional community-preschool clusters to support reaching desired sample size, provided these sites meet the project timeline. This sample size is therefore based on practical assumptions, for the purposes of pilot/feasibility testing.

Feasibility outcomes will be analysed and presented as summary statistics, mean and standard deviation for continuous approximately normally distributed data, median and inter quartile range for skewed continuous data and proportions for categorical data.
