Description of intervention(s) / exposure
The Healthy Youngsters Healthy Dads (HYHD) intervention is the same as that described in the RCT (ACTRN12619000105145).

In summary, the program is implemented face-to-face over 8 weeks with two ‘dads-only’ information workshops and eight weekly ‘dads-and-youngsters’ education and practical sessions. The two 'dads-only' workshops occur before week 1 and week 2 of the 'dads-and-youngsters' sessions. During each dads-only workshop, fathers learn evidenced-based strategies to improve their own lifestyle behaviours and parenting practices to improve their children’s physical activity, dietary habits, social-emotional well-being and sports skills.

Each dads-and-youngsters practical session is broken up into 2 components:
(i) A 20-minute educational session based on weekly theme, conducted for fathers and children together
(ii) A 55-minute practical session where fathers and children participate together in rough and tumble play (e.g. sock wrestles), health-related fitness (e.g. fitness circuits, shuttle carries) and fundamental movement skills (e.g. catching, kicking, throwing).
Mothers/partners and siblings will also be invited to attend session 5 of the program, where all family members participate in all activities together.

In addition to these sessions, participants will receive the following program resources:
- A t-shirt, water bottle and bag
- An activity handbook developed for this study with a range of activities for fathers and children to complete at home between sessions. The activities include goal setting, fundamental movement skill practice, physical activity tracking and home challenges that match each session theme (e.g. nutrition, screen time, physical activity) (approx. 30-minute time commitment per week).

Both components will be delivered by local trained facilitators (qualified teachers and student teachers) at either the University of Newcastle or at local primary schools in the Newcastle region. All facilitators will attend a training course delivered by Professor Philip Morgan at the University of Newcastle where they will learn how to deliver the HYHD program and will receive resources to support their facilitation (e.g. facilitator manual).

When translating evidence-based programs into real-world settings ongoing modifications are required based on the unique characteristics of the settings and populations. Modifications will be made to the program based on both outcome and process evaluation of each subsequent program implementation in 2019 and 2020. The goal will be to develop a comprehensive model of a real-world intervention for application in communities through updating materials, developing standardized train-the-trainer education and resources and ongoing evaluation of the intervention implementation with a final evaluation conducted in 2020.

Outcomes
Primary outcome [1] 321639 0
The primary trial outcome will be whether or not at least 4 of the following 5 process outcomes are achieved.
1. Fidelity of the program delivery - Fidelity will be defined as successful delivery of at least 80% of the session content by facilitators during the fathers-only workshops and the dads & youngster sessions (including physical activity tasks (e.g. rough and tumble play, sport skills and fitness)). This will be measured by weekly post session reflections completed by the facilitators and an independent observation of at least two sessions per program.
2. Attendance – as measured by percentage of HYHD sessions attended. Defined as at least 70% attendance at the fathers-only workshops and the father-and-child sessions on average across the eight weeks.
3. Compliance – as measured by the number of home tasks completed by Dads and their Youngsters. Successful compliance will be defined as Families completing at least 70% of the home-based tasks in the activity handbook. The activity handbooks will be collected after the final session by the University of Newcastle research team and the number of activities completed will be recorded.
4. Satisfaction – Success will be defined as a mean score of at least 4 out of 5 for satisfaction items measured via questionnaire using a 5-point Likert scale.
5. Recruitment – achievement of recruitment targets for participants (at least 12 families per program), HYHD programs (at least 4 per year) and host community locations (at least 2 different locations).

Statistical methods / analysis
Mixed effects regression models will be used to investigate the outcomes. Mixed effects linear regression, adjusted for cohort year and previous involvement in the RCT (note: 71% of 2019 cohort we involved as a control group in related RCT), will be used to compare Father Self-efficacy score, Co-parenting score, and all three dietary intake variables (Dad and Child) at each of the applicable follow-up times. Mixed effects negative binomial regression, adjusted for cohort year and involvement in the RCT, will be used to compare MVPA and Weekly Average Screen time (Dad and Child) at each of the applicable follow-up times. Mixed effects gamma regression, with no adjustment, will be used to compare Average Steps/Day (Dad and Child) at each of the applicable follow-up times. Random individual-level intercepts will be included in all models to adjust for correlation of outcomes due to the same individual being measured at multiple timepoints. Correlation between individuals who undertook the program in the same session will also investigated through nested random intercept models. Correlation will be retained only in models for dad outcomes of Average Screen time and the Dietary Intake variables. In all other instances the correlation was found to be negligible and removed from the model. Model estimates (rate ratio [RR], or average difference) with 95% confidence intervals (CIs) and p-values will be presented. For all models, statistical significance is assessed at the 5% level.

Mixed effects hurdle gamma regression models, with random individual-level intercepts, will be used to investigate outcomes of Father-child co-physical activity (solo and family) and number of nights dinner consumed in front of TV (dad and child). These models separate the outcome into a binary and gamma component. For the binary component, a 1 is given when the outcome has a value of zero and a 0 given for non-zero values of the outcome. The binary component is then modelled via a mixed effects logistic regression with an odds ratio (OR) with 95% confidence interval (CIs) and p-value presented. Non-zero outcome values are then modelled via a mixed effects gamma regression with a rate ratio (RR) with 95% confidence interval (CI) and p-value presented.
Missing data will be handled using the mixed modelling framework.

For all outcomes, with the exception of dad and child Average Steps/Day, all models described above were repeated with the fixed effect for previous involvement in the RCT (previous involvement in program) removed. Model estimates were then compared to those from the main analysis.
