Description of intervention(s) / exposure
The INTERgeneAtional Clinical-Trial In at-risk Older-adults and pre-school childreN (INTERACTION) is a two-site internal pilot trial to understand whether a community-based Intergenerational Practice (I-P) in preschool children and at-risk older adults is likely to be efficacious in reducing transition to frailty. This will be a 10-week trial of intergenerational practice at one site compared to a contemporaneous wait-list control at another site.

The I-P intervention consists of 10 weekly 2 hour sessions that will be delivered in church or community hall settings close to the participating pre-school sites. Each session brings together 10 children from the affiliated pre-school and 12 older adults from the local community. The nature of the Early Years Learning Framework and the importance of engaging both older adults and children mean that there is some flexibility as to the chosen activities. Each session must include at least one physical, one cognitive and one social activity, but the main focus may vary depending on the participants' preferences. The sessions include multi-modal intergenerational activities targeting physical, cognitive function and mood, and are tailored to the Early-Years Learning Framework. The activities are designed specifically for this study. Examples of activities include dancing, dress-up and role play and storytelling.

Sessions will be delivered by trained and experienced child educators supported by research staff familiar with working with older adults. All adults participating in or supporting the sessions are required to have a current working with children check.

Prevention
Comparator / control treatment
The control group is a contemporaneous wait-list control site that will recruit 10 children and 12 older adults the same way as the active site but will receive no intergenerational practice sessions during the research period. The wait-list control site will receive 10 weeks of intergenerational sessions after the end of their assessment (control) period. This is a best practice arrangement to reduce attrition.

Statistical methods / analysis
Descriptive statistics will be used to describe older adult and child participant populations.

The binary general health measures (e.g. diabetes Y/N) will be combined into a frailty index which provides a score between 0-1 (Searle et al 2008).

Cognitive scores will be converted to z-scores and averaged per cognitive domain and overall to provide a general measure of cognitive functioning.

The distributions of each continuous or quasi-continuous outcome variable (cognitive function, SF36 sub-scale scores, frailty index, grip strength etc.) will be examined and transformed where necessary.

Initial analyses comparing pre-post testing will use paired t-tests or Wilcoxon rank tests as appropriate.

Pre-post accuracy scores (% correct) from child assessments will also be compared.
Linear regression models will be used to evaluate change in outcome measures adjusted for baseline scores and sociodemographic variables (e.g. age, sex, educational level) in order to provide estimates of effect size for a future confirmatory large trial.

Video recordings of interactions between the participants will be coded to quantify the quality and reciprocal responsiveness of the relationships between the children and older adults at multiple timepoints throughout the 10-week session.

Planning for a subsequent trial and for potential future translation, will also be informed by data on source of recruitment (from community, word of mouth, social media, advertisements in clinic etc), eligibility, consent, and attrition rates.
