Difficulties in executive functioning (EF) can result in impulsivity, forgetfulness, and inattention. Children living in remote/regional communities are particularly at risk of impairment in these cognitive skills due to reduced educational engagement and poorer access to interventions. This vulnerability has been exacerbated by the COVID-19 pandemic and strategies are needed to mitigate long-term negative impacts on EF. Here we propose a pilot trial investigating the benefits, feasibility, and acceptability of a school-based EF intervention for primary school students (6-8 years) living in regional, developmentally vulnerable, and socio-economically disadvantaged communities. Students were randomised to a digital intervention or teaching as usual, for 7 weeks. Children completed measures of EF and parents/educators completed ratings of everyday EF and social/emotional wellbeing at pre-intervention, post-intervention, and 3-month follow-up. Change in EFs (primary outcome), everyday EF, and social/emotional wellbeing (secondary outcomes) from pre- to post-intervention and pre-intervention to 3-month follow-up were examined. Feasibility and acceptability of the intervention was assessed through educator feedback and intervention adherence.Protocol Registration: The stage 1 protocol for this Registered Report was accepted in principle on 20 April 2023.
