Study type
Interventional
Description of intervention(s) / exposure
Primary health care workers (Interventionists) in the treatment group will be trained to deliver the WHO/UNICEF Care for Child Development (CCD) package at each child health check in the first year of life. The CCD package promotes caregivers’ sensitivity and responsiveness using developmentally appropriate play and communication activities. The package contains a set of age-specific messages about care for child development and problem-solving. Caregivers try an age-specific play using objects readily available in the home and communication activities with their child while the primary health care worker observes, coaches, and provides feedback to enhance the quality of the interactions. Examples for infants 1 week up to 6 months include providing ways for child to see, hear, feel and move freely. Slowly move colourful things for the child to see and reach. Smiling and laughing with the child. Talking to the child. Get a conversation going by copying child’s sounds or gestures. Parents and caregivers will be encouraged to engage in activities with their child at every available opportunity.
In our trial, twelve Interventionists will be employed to deliver the CCD package at universal child health checks within the first 12 months: birth-14 days, eight weeks, four months, 12 months. Depending on availability of families, each visit takes approximately 7-30 minutes and can be delivered individually or as a group. The Interventionists in the first instance will be Aboriginal Health Workers and, when not available, nurses or child health nurses who have experience working with Aboriginal families. All interventionists will receive extensive training and ongoing mentoring on how to deliver the CCD package. The training will be delivered by trained trainers (Facilitators). These facilitators (child health nurse and or midwife) will be provided face to face training by the Supervisor trainer (social psychologist and program developer). This training will be for 1 week (40hrs) and include an extra observed practice with 20 caregiver counselling interactions (up to an extra week). The trial interventionists will be trained by the Facilitators. This training will be for 3 – 4 days. Interventionists will also be observed for 10 hours following initial training. The supervisor trainer will then provide online support and observation for each interventionist and facilitator for one hour each month.

A process evaluation will be developed to monitor and evaluate the intervention implementation. This will use the existing monitoring and evaluating tools developed by UNICEF and WHO developed specifically for the intervention.

Comparator / control treatment
The control group will receive Universal Services, Universal Plus, and Partnership Child Health Services depending on the child's need from their respective health services and determined by the assessing clinician in accordance with evidence based universal contact guidelines. Western Australian child health checks completed in the first year are from birth-14 days, eight weeks, four months, and 12 months. During these checks (30 mins), families are expected to receive information on physical, social and emotional development and sensitive responses to their child’s cues. Children in the control group will not receive any additional CCD support.

Study design
Purpose of the study
Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
The random allocation schedule will be generated by a statistician independent of the trial, who will upload the schedule into REDCap. The schedule will not be accessible by the Recruitment/Retention Officer until assignment, at which time the allocation will become available upon entering the participant's details. The randomisation will be restricted using one large permuted block for the entire trial to ensure the allocation ratio is maintained at the end of the trial. For infants assigned to the CCD group, they will also be randomly assigned to a health care worker who will deliver the CCD package throughout the trial. In addition to randomising infants to interventions, randomising infants to health care workers has the benefit of reducing confounding bias due to variation in health care worker and infant characteristics.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The randomisation will be restricted using one large permuted block for the entire trial to ensure the allocation ratio is maintained at the end of the trial.

Sample size estimation
The sample size calculation is based on the findings from two trials included in our review (with an effective same size of 244 participants) that examined the effect of combined responsive caregiving and early learning on cognitive development. The meta-analysed effect indicated an improvement of 6.1 (95% CI -4.3 to 16.5) units at 12 months on the Bayley scale (range 0 to 160) for those receiving the intervention compared with usual care. A difference of this size has been shown to have an important impact, equivalent to improvements arising from breastfeeding for more than eight months. A sample of 204 and 200 infants in the intervention and control groups, respectively, will be sufficient to detect a difference of 6.1 with 90% power. This assumes a two- sided alpha = 0.05, a standard deviation of 15.2 (assumed from the largest trial, so yielding the most stable estimate), and includes adjustment for potential clustering arising in the intervention group from each health care worker (HCW) delivering the intervention to multiple participants (assuming an intra- HCW-correlation [I-HCW-C] of 0.05, 12 HCWs, and 17 infants per HCW). This calculation is sensitive to the assumption regarding the size of the I-HCW-C; however, estimates of I-HCW-C < 0.11 will still yield at least 80% power. Adjusting for an anticipated 20% attrition, we plan to recruit 264 (22 infants per HCW) infants in the intervention and 250 infants in the control group.

Statistical methods and/or analysis plan
Effectiveness analysis - Linear mixed models will be used to estimate the intervention effects. These models will include a random effect for the health care worker, a term for time and an interaction term between time and intervention group, allowing the magnitude of the effect to vary by time. Data will be analysed according to the group that participants were randomised. Linear mixed models yield unbiased estimates of intervention effect when data are missing completely or missing at random. Sensitivity analyses will also be undertaken to investigate the robustness of the intervention estimates to different assumptions about the missing data.

Cost-effectiveness analysis - A Cost-Effectiveness Analysis (CEA) will be undertaken of the CCD intervention compared to usual care for outcomes: infant cognitive development, language and motor development and maternal mental health at 12 and 24 months. The CEA will examine whether CCD interventions improve the early child neurodevelopment of the Aboriginal children and maternal mental health of the Aboriginal mothers and thus bring better value for money for WA health systems. Five separate CEA models will be developed based on the outcomes from the perspective of the WA health system. The reference year for CEA will be 2026. Costs and outcomes data will be collected from the CCD interventions and usual care comparator group. Annuitization will be done for the capital items and machineries with a lifespan of more than one year, applying a 5% discount rate.

The total cost for CCD intervention and usual care will be estimated and calculate the average cost per child and mother for interventions and usual care separately. Five incremental cost-effectiveness ratios, the incremental cost per additional outcome for CCD interventions compared to the usual care will then be calculated. Five cost-effectiveness planes will be drawn applying 5000 bootstrap simulations and scatterplot in order to demonstrate dominant intervention and thus will identify the most cost-effective/cost-saving intervention. 95% confidence intervals will be estimated using bootstrapped 5000 replications to examine the distribution of each of our five ICER (incremental cost-effectiveness ratio) estimates. Sensitivity analysis will also be undertaken using plausible assumptions to examine the robustness of the original ICER estimates.
