Outdoor nature-based play in early learning and childcare centres: Identifying the determinants of implementation using causal loop diagrams and social network analysis.

Nature-based play benefits children's health and development. However, the delivery of this in early learning and childcare centres (ELC) is extremely diverse, and implementation is not well understood. We applied a systems science perspective to understand the factors crucial to implementing nature-based outdoor play in ELC settings. Through Group Model Building workshops with 20 participants in managerial and practitioner roles, crucial factors were appraised using Causal Loops Diagrams. Twelve thematic causal loops emerged. Network analysis was employed to analyse the diagram. Exponential Random graph models explained the diagram construction process. Centrality measures alongside conditional uniform tests identified six leverage factors: use of outdoor space, culture of being outdoors, ELC culture of outdoor play, perceived child safety and enjoyment, educator confidence and educator agency. This research brings novel and practically relevant evidence about the important factors, and interdependencies, involved in the implementation of outdoor play practice within ELC settings.
