Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The Embrace Parent Masterclass is a micro-intervention (5-minute online video) that presents strategies for parents aimed at promoting positive body image and healthy eating behaviours in children. The intervention was developed by body image expert Dr Zali Yager, and was based on key findings from a Delphi study focused on prevention guidelines for parents and researchers (Hart et al., 2014). The key messages from the masterclass include: (1) understanding body image; (2) raising awareness of language and negative body talk; (3) focusing on body functionality; (4) celebrating diversity/embracing different bodies; (5) not labelling food as ‘good’ or ‘bad’; (6) social media literacy; (7) strategies for addressing negative body talk in children; and (8) complimenting children beyond their appearance. The masterclass is delivered by an Australia comedian and father of two, Nazeem Hussain, who delivers the key messages in an engaging, fun and concise way and is freely available to Australian audiences through the Embrace Hub website (https://theembracehub.com). Masterclass messages are delivered verbally and are accompanied by animations throughout the video. To monitor engagement with the intervention material, participants were asked a qualitative questions about the video content, such as: 'In a few short sentences, please describe the key takeaway messages from the parent video you have just watched.' Additionally, one attention check question was included to assess whether participants had engaged with the content. No website analytics or tracking tools were used to monitor viewing.

Prevention
Comparator / control treatment
In the active control condition, parents viewed a short, animated cartoon titled “Shark Music” part of the Circle of Security parenting program. This 5-minute video, freely available on YouTube (https://www.youtube.com/watch?v=UYy4iLtTwxk), introduces core themes of the Circle of Security model through a relatable and engaging metaphor. “Shark Music” illustrates how parents’ internal anxieties can unintentionally affect their responses to their children, creating a barrier to connection. In the animation, rather than depicting real people, the use of cartoon visuals allows viewers to engage with these ideas more universally. The key message encourages parents to recognise and manage their own emotional responses, promoting a secure, supportive environment for their child. There was no focus on appearance-related messages. As such, the video was considered an appropriate control given its focus on parenting practices.

Statistical methods / analysis
All quantitative data analyses were conducted using IBM Statistical Package for the Social Sciences version 28 (IBM Corp, 2024). Means and standard deviations of all study variables were examined. Independent samples t-tests were conducted to examine any baseline differences between the Embrace Parent Masterclass group and the active control group. To assess the effects of intervention group on our primary outcomes (knowledge, awareness and competency), two-way univariate analyses of covariance (ANCOVAs) were conducted for each variable, covarying for the relevant knowledge, awareness or competency baseline score.
Moderated regression analyses were used to evaluate the potential moderating effects of eating disorder symptoms and parental self-efficacy on our primary outcome variables (knowledge, awareness and competency). Hierarchical Regression Analyses were conducted whilst covarying for baseline scores (entered in Step 1), condition (coded as: 0 = control; 1 = intervention) and moderator variable scores were entered at Step 2 and interaction terms (Condition x Moderator) were entered at Step 3. Continuous moderator variables (eating disorder symptoms and parental self-efficacy) were mean centred prior to creating the interaction terms to reduce multicollinearity and improve interpretability of the results (West et al., 1991). The significance of the R-squared change value at Step 3 was used to determine the presence of significant moderation effects.
