Examples of Interventions Under Review: Violence Prevention Chapter Early childhood home visitation programs Legislation restricting availability, sales, access, safety, deployment of firearms • Therapeutic foster care • Trying/sentencing/incarcerating juveniles as adults • Programs for the development of prosocial skills Community policing Etc.
Community Guide Methods: Suitability of Design • Greatest • Prospective with concurrent comparison • Moderate • Multiple pre/post measurements but no concurrent comparison OR • Retrospective • Least (may be excluded) • Single group before-and-after • Cross sectional

Community Guide Methods: Criteria for Evidence of Effectiveness
Child maltreatment reports in the US Approximately 4.3% of children (<18 years) in 1996 Source: National Center for Juvenile Justice, 1999
Definition: Early Childhood Home Visitation • Home visitation of parent(s) and child(ren) by trained personnel who: • convey information, and/or • offer support, and/or • provide training • Programs systematically reviewed only if they assess violence-related outcomes
Definition (cont’d): Home Visitation • Visits may address: • training on infant care • training on parenting • training on problem solving • preventing child abuse and neglect • family planning assistance • educational and work opportunities for parents • community service linkage
Definition (cont’d): Home Visitation • Visitation must occur during first 2 years of child’s life; may begin prenatally and/or continue after age 2 • Participation voluntary or mandated • Visitors: nurses, social workers, trained para-professionals, community peers, others • Often targeted: low income, minority, single, young mothers, low birthweight infant, etc.
The Need is Great In 1999, of 3.6 million births: • 12% of mothers were teens • 33% were single • 22% had <12 years of school • 43% (1.5 million) had >1 of these characteristics
Analytic Framework: Early Childhood Home Visitation Violence by adolescent parent(s) Parent Knowledge Skills Self-confidence Access to resources Parenting Home visitation program Partner abuse by adolescent parent Child Development Skills Health/ well-being Child maltreatment Violent act by juvenile
Proposed Recommendations • Violent act by juvenile - inconsistent findings: insufficient evidence • Violence by parents – suggestive findings: insufficient evidence • Partner abuse of parent – possibly ineffective: insufficient evidence • Child maltreatment- effective:recommended, strong evidence
Child Maltreatment Child maltreatment (or victimization) includes abuse and neglect
Direct Measures CPS reports Parent’s reports Other report or observation of abuse, neglect, or victimization Proxy Measures ER visits/ hospitalization for injury or ingestion Injury Out-of-home placement Measures of Child Maltreatment Direct measures chosen over proxy measures
Study Ratings Number of intervention arms (number of studies)
Effect size measure Effect size = Relative change in intervention group compared with relative change in intervention group

Home Visitation Effects by Duration of Program Spearman correlation: Whole sample: -0.52 (p=0.01) Paraprofessionals: -0.63 (p<0.01) Professionals: -0.32 (NS)
Other stratified analyses No significant effect modification when stratified by: • Program content (multi- vs. single-component) • Time of initiation (pre- vs. post-natal) • Group allocation procedure (randomized vs. non-randomized) • Execution quality score
Strong evidence to recommend Greater effect with professional home visitors With paraprofessional visitors, a beneficial effect is found with longer program duration Conclusion: Effects of Early Childhood Visitation on Child Maltreatment

Children: Improved mental and physical health Better access to, and use of, medical care Improved immunization coverage Improved school achievement Parents: Improved family planning (e.g., spacing of pregnancies) Improved home environment Higher level of education Other Reported Benefits
Olds (Elmira, 1994) reports greater “restriction and punishment” among home-visited than among control parents. Evidence suggests an association among home visited mothers of “restriction and punishment” and lower rates of injury. Stigmatization by target group criteria (e.g., low SES, single, minority, at risk for maltreatment) Other Reported and Potential Harms
Retention of participants, even in research study settings. Many participants lead difficult lives with few resources. Move frequently Unemployment and job transitions Lack of interest Retention of home-visiting personnel Reported Barriers
Many early childhood home visitation programs reviewed were targeted at populations considered to be at high risk of poorer child well-being and related outcomes. Although Olds reports greater or more significant effects among single, low-SES-mother families, no general demographic characteristics distinguish more or less successful programs. Applicability
Conclusion • Early childhood home visitation: • Effective in prevention of child maltreatment • Greater effects are found with programs delivered by professionals (e.g., nurses or mental health workers) • With paraprofessional visitors, beneficial effects are found with programs of longer duration. • Additional maternal and some child benefits; minor harms reported
Strong evidence to recommend Greater effect with professional home visitors With paraprofessional visitors, a beneficial effect is found with longer program duration Conclusion: Effects of Early Childhood Visitation on Child Maltreatment
