The child data set includes the responses of 579 children in families of which the reponses have been recorded of manual-based sessions done on groups of families with pre-adolescent children (9-11 years) and evaluated using a treatment versus no treatment repeated-measures design. Each session of the manual covers ten topics that include children's rights and responsibilities; parental styles; communication; puberty; hard to talk about issues; risky environmental influences; understanding HIV/AIDS; dealing with stigma; surviving loss and bereavement; developing support networks. The effect of the intervention was measured along all of these dimensions. This data set contains the responses of both the pre-test and the post-test. The responses of the pre- and post-test were merged into one data set.
