Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The 3PS intervention will consist of a half-day, group-based workshop with parents of toddlers, which will be run by a community worker. The workshop will focus on the home environment and organisation in the home, with the ultimate aim of reducing household chaos. Within this context, specific topics of sleep, diet, and play/screen use will be discussed, and simple solutions offered to busy parents to overcome barriers to their toddler engaging in health-promoting behaviours and routines, such as family meals and adequate sleep. The workshop will be run with approximately 10-15 parents, and will involve a mix of traditional presentations (e.g. PowerPoint presentation presented by the facilitator), videos, and group exercises. The workshop will be audio recorded to check fidelity of the content delivery.

The workshop will also be supplemented by a study website, which will provide an overview of each of the topics explored in the workshop, in addition to in-depth information for those parents seeking more information around a specific topic. The website will also contain short videos, which will focus on sleep, diet, and play/screen use in toddlers. Participants will have access to the website for a period of 6 weeks. Google analytics will be used to assess usage of the website, and participants will be sent an email each week for the first 4 weeks introducing them to each of the topics and linking to the specific page. For example, during the first week, participants will receive an email briefly discussing the importance of routines and rituals, and a link to this page on the study website.

Behaviour
Comparator / control treatment
Wait-list control. Participants in the wait-list control will not participate in the workshop or have access to the website for the duration of the study. However, once final follow-up is complete (12 weeks post-workshop) all control participants will be offered the opportunity to attend the half-day workshop and will be given access to the study website.

Outcomes
Primary outcome [1] 305708 0
Screen use: Assessed using four questions from the New Zealand Health Survey. Parent-report of time (in hours) child spends watching TV or using ‘other’ screen devices during weekdays and on weekends. An average weighted score for TV and ‘other’ screen time will then be calculated and the proportion of children meeting international guidelines (0 hours for children aged under 2 years and <1 hour per day for children aged 2-3 years) will be calculated.
Timepoint [1] 305708 0
Baseline, 6 weeks (primary), 12 weeks post-intervention commencement.
Secondary outcome [1] 346210 0
Restrained time: Assessed using 6 questions. Parent-report of the amount of time (in minutes) and number of times per day (frequency) their child is restrained in a car seat, a pram, and a high chair. Time spent in each of the ‘restrictive’ devices and frequency of child being placed in each of the ‘restrictive’ devices will then be calculated.

Baseline, 6 weeks, 12 weeks post-intervention commencement.
Secondary outcome [2] 346211 0
Nutrition: Four questions from the New Zealand Health Survey investigating number of fruit and vegetable servings, fizzy drink consumption, and fast food consumption, and one question from the Family Routines Inventory, investigating number of days per week that the family sit together to eat the main meal. Parent-report of child behaviours.

Efficacy
Statistical methods / analysis
Baseline characteristics will be summarised using descriptive statistics. Continuous variables will be presented as mean and standard deviation (SD). Categorical variables will be presented as frequency and percentage. All statistical tests will be two-sided and maintained at a 5% significance level. Categorical variables will be reported as n and %. Simple chi-squared analyses will be used to evaluate the treatment effect on the proportions adherent to screen use guidelines after 6 weeks, with estimation of relative risks, 95% confidence intervals and two-sided p-values.
As this is a feasibility study, no power calculation will be performed to assess participant numbers.

Summary
Brief summary
The aim of this research is to explore how reducing household chaos and encouraging engagement in positive family routines may promote development of healthy lifestyle behaviours that reduce the risk of overweight and improve well-being in young New Zealand children. A two-arm, 12-week RCT pilot study will be conducted to assess the Three Pillars Study (3PS) programme. Intervention participants will attend a half-day workshop and then have access to a supplementary website with more information, resources, and videos. Both the intervention group and wait-list control group will undergo study measures at baseline, 6 weeks (at the end of the programme) and 12 weeks (final follow-up). After final follow-up data collection has been completed, the control group will be offered the intervention, that is, participation in the half-day workshop and access to the study website.
