We investigated whether parents who reported more positive parenting practices (i.e., monitoring, involvement, and communication) reported more discussion of child sexual abuse (CSA) with their children. Parents from Australia and the UK (N = 248), with children aged 6 to 11 years, completed an online survey. About half of parents reported directly discussing CSA, whereas 35% reported telling their children that CSA perpetrators may be family members. Rates of discussion were higher for other CSA-related topics such as body integrity and abduction. Correlational analyses showed that parents who reported speaking to their children about CSA also reported more positive parenting practices, more discussion of other sensitive topics, and assessed CSA risk for children (in general) to be higher. Discussion of CSA risk was not associated with parents' CSA knowledge, confidence or appraisal of own-child risk. Parents higher in positive parenting believed their children to be at less CSA risk. Parents who appraised higher own-child risk reported less positive parenting practices and were less confident about their parenting and their ability to protect their children from CSA. The findings are the first to report on the associations of parenting practices with parents' CSA discussion with their children.
