Description of intervention(s) / exposure
INTERVENTION
In-person intervention (Arm 1)
Families will be asked to attend two sets of Respectful Approach parenting classes, held in a group setting (approximately 8-10 children with their primary carers/parents). The Respectful Approach is a preventative initiative, based on principles of the ‘Pikler Approach®’ originally developed by Hungarian paediatrician Dr Emmi Pikler and later established in the USA by infant specialist Magda Gerber.

Each set of classes will run once per week for eight weeks (for a total of 16 classes over the two sessions). Families will attend the first set of classes when their child is around four months of age and the second set of classes when their child is around twelve months of age. For the in-person classes, children will attend with their parents to provide ‘live’ opportunities for sensitive observation and interactions. Session attendance will be taken and parents in the intervention will be encouraged to complete and reflect on weekly challenges . These will be used to assess adherence to the Respectful Approach principles. Families will also be invited to engage in a private, researcher-supervised Facebook group for on-going peer support.

Online intervention (Arm 2)
Families will attend the classes covering the same content as the in-person group but over web video conference. For the online classes, families will be invited to submit a video of their child for discussion. All assessments will be the same as the in-person intervention.

THE CLASSES
The parent-child classes will be facilitated by qualified educators experienced in running classes and parent education, and also have completed additional specialist training in the Respectful Approach (RIE® Foundations: Theory and Observation). Each class will run for around 1 hour. Classes cover a different topic each week based on Respectful Approach principles of mutual trust, sensitive observation, quality caregiving (with a focus on mealtimes), a prepared environment, time for uninterrupted play and consistency. Participants will receive weekly handouts including educational information around the topic for discussion for that week. These handouts have been specifically designed for this study.

INTERVENTION LOCATION
- Arm 1: in-person sessions will be provided for free at an appropriate venue within the
Perth Metropolitan region (e.g., community centre)
- Arm 2: online classes will be held via video conferencing software (e.g., Microsoft Teams or Zoom)

Comparator / control treatment
The control group will consist of parents/carers attending facilitated outdoor play group classes without any education. Classes will occur at similar time periods to the intervention groups, which will enable us to determine whether any beneficial effects observed from baseline measures are due to the social/group aspects or the Respectful Approach program itself. The outdoor play group will provide some activity stations appropriate to the age of the child, involving items such as blocks, books, sticks, large rocks etc.

SAMPLE SIZE

A-priori sample size requirement was calculated using G*Power. Based on results from our pilot study, for a mixed-model repeated-measures design with three groups (two intervention groups, one control) and three time points, the minimum required sample size to detect, at least, a small-to-medium Group × Time interaction effect (Cohen’s f = 0.175) at 90% power and 1 % level of significance (to account for multiple parent- and child-related outcomes including confidence and stress) is 117 (39 per group). However, a common problem that arises in early parenting longitudinal studies is the high rates of attrition, with
Bigelow (2018) reporting high rates of attrition over a 12-month period, mostly due to parents returning to the workforce. Therefore, assuming a 20% attrition rate, the adjusted required sample size is 141 (47 per group). As we would also like to access ORIGINS data to assess outcomes at 3 and 5 years, we have added an additional 30 ORIGINS participants to account for longitudinal drop out/loss to follow up to this time point (total n = 171, 57 per group).

DATA ANALYSIS
Quantitative data from self-report questionnaires, observations and voice recordings will be analysed using SPSS Statistics Version 24.0 (IBM Corp, 2016). A linear mixed model will be used to determine any statistically significant variations between the intervention and control groups across all measures over the intervention periods, to ascertain the effect of a ‘Respectful Approach’ intervention. Confounding factors will be evaluated and included as covariates in the linear mixed model. Some potential confounding factors include age, education level, first time parent, single parent (or marital status), history of depression. Results will be deemed significant if p<0.05. As recommended, we will report results from fully adjusted as well as crude analyses.
