The home physical environment has an important influence on children’s physical activity levels and time spent in sedentary behaviours. The aim of this study was to validate the HomeSPACE-II instrument for use in two-storey homes, to measure physical environmental factors that influence children’s physical activity and sedentary behaviours within the home. Parents (n = 31) with at least one child aged 9–13 years completed the instrument independently alongside a criterion-trained researcher, then one week later alone, to assess validity and reliability, respectively. Parents were mostly female (87.1%) and university educated (61.3%) with a mean age of 41.68 ± 4 years, while houses were mostly semi-detached or terraced (61.3%) with two parents (87.1%). Intra-class correlation coefficients, Pearson correlation coefficients and Kappa statistics revealed that most items, outside of accessibility and size measures, had strong reliability and validity (94% having ICC > 0.60 and 97% having r > 0.80). Excluding physical activity equipment, accessibility items with lower reliability and validity had low between-subject variation. The HomeSPACE-II instrument covers a wide range of parameters within the home and demonstrated strong validity and reliability, suggesting it is a useful tool for measuring physical factors that influence children’s physical activity and sedentary behaviour within the home.
