Data, materials, and analytic code for universal preschool-based interventions to promote self-regulation: A systematic review and meta-analysis

This Open Science Framework (OSF) project contains the data, supporting materials, and analysis code for the Campbell systematic review and meta-analysis Universal preschool-based interventions to promote self-regulation: A systematic review and meta-analysis. Files are organised into five folders covering search and screening, data extraction, risk of bias, analyses (dataset, codebook, and R Markdown scripts with outputs, plus the GRADE evidence profile), and reporting checklists. A README explains the folder structure and how to reproduce the analyses.
