The strong and ever-growing evidence base demonstrating that physical punishment places children at risk for a range of negative outcomes, coupled with global recognition of children’s inherent rights to protection and dignity, has led to the emergence of programs specifically designed to prevent physical punishment by parents. This paper describes promising programs and strategies designed for each of three levels of intervention − indicated, selective, and universal − and summarizes the existing evidence base of each. Areas for further program development and evaluation are identified.  相似文献

This randomized controlled trial (RCT) examined the effects of the Second Step Child Protection Unit videos on parents’ knowledge, motivation, and self-reported communication with their child about personal safety and childhood sexual abuse prevention. Parents of children between the ages of 3–11 years were randomly assigned to the intervention (watching the Second Step videos) or the control (watching videos on child obesity) groups. They completed measures assessing their knowledge of child sexual abuse (CSA), motivation to discuss CSA, self-reported discussions of CSA, child history of victimization, parent exposure to CSA, and comparable measures on topics of health and nutrition at pre-test. Participants viewed the videos one week later and immediately completed post-test 1, and then two months later completed the measures again. Multivariate Analyses of Covariance (MANCOVAs) and serial mediation analyses were conducted with the final sample of 438. The intervention group, compared to the control group, had significant increases in knowledge (specifically, less restrictive stereotype beliefs about CSA) and motivation to talk with their children about CSA both immediately after the intervention and at the two-month follow-up. Although the intervention did not have a direct effect on parent self-reported conversations with their children about CSA, it had a mediated effect. The intervention increased knowledge regarding CSA, which then predicted motivation, which in turn predicted conversations. The most pronounced effect was the intervention’s direct effect of increasing motivation immediately after the intervention, which then increased self-reported conversations with children about personal safety and CSA two months later.  相似文献

Objective

As nurse home visiting to prevent child maltreatment grows in popularity with both program administrators and legislators, it is important to understand engagement in such programs in order to improve their community-wide effects. This report examines family demographic and infant health risk factors that predict engagement and follow-through in a universal home-based maltreatment prevention program for new mothers in Durham County, North Carolina.

Methods

Trained staff members attempted to schedule home visits for all new mothers during the birthing hospital stay, and then nurses completed scheduled visits three to five weeks later. Medical record data was used to identify family demographic and infant health risk factors for maltreatment. These variables were used to predict program engagement (scheduling a visit) and follow-through (completing a scheduled visit).

Results

Program staff members were successful in scheduling 78% of eligible families for a visit and completing 85% of scheduled visits. Overall, 66% of eligible families completed at least one visit. Structural equation modeling (SEM) analyses indicated that high demographic risk and low infant health risk were predictive of scheduling a visit. Both low demographic and infant health risk were predictive of visit completion.

Conclusions

Findings suggest that while higher demographic risk increases families’ initial engagement, it might also inhibit their follow-through. Additionally, parents of medically at-risk infants may be particularly difficult to engage in universal home visiting interventions. Implications for recruitment strategies of home visiting programs are discussed.  相似文献
