Description of intervention(s) / exposure
Parenting+ is an innovative health literacy intervention for new parents that is built on a model of health literacy skill development shown to increase health literacy in disadvantaged and culturally-diverse adults in Australia. Parenting+ is a free 4-6 week health literacy program that embeds functional health literacy skills into parenting topics of interest, identified from our previous work, in four core content areas:
Topic 1: Child development
Topic 2: Healthy eating and physical activity
Topic 3: Adjusting for parenthood
Topic 4: First aid, medicine and immunization

To develop transferable health literacy skills, three core skill sets are included across all topics: 1) skills to access and critically appraise health information; 2) skills for shared decision making and 3) skills for implementing health behaviours.

The Parenting+ program will be delivered face-to-face or online in small groups of approximately 6-8 participants by trained facilitators (e.g. Child and Family Health Nurses; bilingual community educators) in community settings (for example, in a community health centre). The Parenting+ program will be delivered as 4 x 2-hour parenting skill development sessions over a 4-6 week period depending upon participant availability. Sessions will include presentations on parenting skills, short video demonstrations, interactive exercises, group discussions, and question-answer.

Parenting+ facilitator training: All Parenting+ facilitators will attend a half-day training session led by the University of Sydney. Training will address adult education theory and practice; behaviour change techniques and health literacy skill development. Training will be conducted at in-person workshops of up to 12 facilitators at least two weeks prior to the first participant enrollment at the site. The training will include the Parenting+ module presentation slides, short videos, and interactive question-answer session. The adherence to the training will be monitored by a session attendance checklist.

Assessment of adherence/fidelity: Facilitators' actions and content covered in each session will be recorded in itemised checklists and logs. Investigators will conduct structured observation of Parenting+ program for content analysis.

Comparator / control treatment
Control groups will attend standard parenting programs (e.g. as organised by Local Health Districts). Community health nurses or equivalent will deliver the standard parenting program face-to-face or online over 4-6 weeks in general. The content, frequency, and duration of the standard parenting program provided at each site will vary depending on local priorities and the structure of the program. Investigators will monitor and document the content and structure provided at the standard parenting program throughout the trial by observation and detailed field notes and will compare the key differences between the standard parenting programs and the Parenting+ intervention.

Secondary outcome [5] 408360 0
Optimal engagement is a composite score combining breastfeeding, infant feeding, immunisation and attendance at scheduled health checks. Individual variables that will be measured to construct the composite score are as follows:
-Self-reported exclusive breastfeeding rates at 6 months and any breastfeeding
-Self-reported infant feeding practices (infant age at introduction of solids, frequency of fruit juice consumption).
-Adherence to scheduled health checks (e.g. immunisation and birth weight checks by self-report at 6, 12 months, immunisation verified against the register at 12 months)
-Adherence to scheduled health checks (e.g. immunisation and birth weight checks by self-report at 6, 12 months, immunisation verified against the register at 12 months)

Efficacy
Statistical methods / analysis
We will randomise 88 clusters (parenting groups) in intervention and control arms (44 clusters in each arm). Each cluster will comprise on average 7 participants. To detect a 0.3 standard deviations difference in parental health literacy skills index between Parenting+ and standard parenting programs with 90% power at a 5% significance level and adjusting for an intra-class correlation coefficient of 0.025 the minimum required sample size is 273 participants in each arm. Allowing for a ~10% loss to follow-up, 616 participants (308 in each arm) will be enrolled in the study.

All analyses will be done by intention-to-treat comparing the intervention and standard parenting group arms (using individual-level data). Mixed-effects regression models adjusting for clustering at the parenting group level will be used for analyses, with intervention included as a fixed effect and controlling for potential confounders. Linear mixed models will be used for continuous dependent variables; logistic mixed models will be used for categorical outcomes.

The cost-effectiveness of Parenting+ intervention (versus usual care) will be analysed from a health funder perspective. An incremental cost-effectiveness ratio will be expressed as incremental cost per quality-adjusted life year (QALY) gained.

Summary
Brief summary
In Australia, 60% of adults have low health literacy. This means that they lack the skills needed to perform
health tasks (such as reading medicine labels) and making health decisions (such as deciding when to access the Emergency Department). Having low health literacy puts people at greater risk of illness and death, and results in increased healthcare costs. When parents have low health literacy, their children have poorer health and are more likely to visit the emergency department and to be admitted to the hospital. Our team has developed a health literacy program to improve parents’ health literacy skills, known as ‘Parenting+’. In 2018, we delivered the Parenting+ program to 73 new parents in western Sydney. We found that the program could be successfully delivered by trained nurses in existing New Parents Groups, including groups for disadvantaged parents. We will now conduct a cluster randomized controlled trial to evaluate the impact Parenting+ has on parents’ health literacy, health outcomes and use of health services compared to standard parenting groups.
