Collected Dataset / QNTS_Grade 4

Data was collected using school-based assessments including behavioral observations which were conducted in a controlled setting, cognitive assessments, and peer and teacher assessments. Direct and multi-faceted assessments of cognitive development were performed as well. In addition, peer relationships and experiences were measured through peers’ assessments, classroom sociometric interviews and 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.
