We apply this framework to the Kids SIPsmartER (KSS) program, a 6‐month, school‐based intervention evaluated through a clustered randomized controlled trial in rural

Our results show that national CPI data may be useful for approximating national trends but they fail to detect and identify spatial variations in local trends, which

This study examines how visits to school and public libraries relate to pupils' reading attitudes, practices and self‐assessed reading ...
