Data Collection Event
QNTS - Grade 3
Data was collected from teacher ratings and children’s school achievement.
Parenting behaviors were assessed yearly, through mother and father self-reports of parental warmth, self-efficacy and impact, overprotection, and hostile-reactive behavior. Social behaviors are also assessed yearly using a variant of the Child Social Behaviour Questionnaire. Also, some of the measures of the children’s environment collected regularly were about nutrition, the mental health status of parents, marital satisfaction and status, as well as a variety of socio-economic and demographic characteristics. Finally, direct and multi-faceted assessments of cognitive development were performed.
