Cross-cultural, age and gender validation of a computerised questionnaire measuring personal, social and environmental associations with children's physical activity (2008)
the European youth heart study
This study investigated the construct validity of a computerised self-assessment tool to measure psychological, social and environmental influences of young peoples’ physical activity. First, analyses of the measure’s factorial validity, invariance across, age, gender culture were conducted. Second, the ability of the derived subscales to discriminate between children representing different levels of self-reported and objectively measured physical activity behaviour was examined.
