Evidence of Model Effectiveness

This model meets the criteria established by the Department of Health and Human Services (HHS) for an “evidence-based early childhood home visiting service delivery model” for the general population, but does not meet the criteria for tribal populations.

Model Description

Home Instruction for Parents of Preschool Youngsters (HIPPY) aims to promote preschoolers’ school readiness and support parents as their children’s first teacher by providing instruction in the home. The model is designed for parents who lack confidence in their ability to prepare their children for school, including parents with past negative school experiences or limited financial resources. HIPPY offers weekly, hour-long home visits for 30 weeks per year, and two-hour group meetings at least six times per year. HIPPY sites are encouraged to offer the three-year model serving 3- to 5-year olds, but can offer a two-year model. The home visiting paraprofessionals are typically drawn from the same population that is served by a HIPPY site, and each site is staffed by a professional program coordinator who oversees implementation and supervises the home visitors. For more information, please read the Model Overview.

This table summarizes the effects found in research across outcome domains. Outcomes with a favorable impact are listed in green and outcomes with an unfavorable or ambiguous impact are listed in red. Outcomes that have high attrition or lack of baseline equivalence are excluded from this report.

Favorable Impact: A statistically significant impact on an outcome measure in a direction that is beneficial for children and parents. This impact could statistically be positive or negative, and is determined “favorable” based on the end result. For example, a favorable impact could be an increase in children’s vocabulary or daily reading to children by parents, or a reduction in harsh parenting practices or maternal depression.

Unfavorable or Ambiguous Impact: A statistically significant impact on an outcome measure in a direction that may indicate potential harm to children and/or parents. This impact could statistically be positive or negative, and is determined “unfavorable or ambiguous” based on the end result. NOTE: While some outcomes are clearly unfavorable, for other outcomes it is not as clear which direction is desirable. For example, an increase in children’s behavior problems is clearly unfavorable, while an increase in number of days mothers are hospitalized is more ambiguous. This may be viewed as an unfavorable impact because it indicates that mothers have more health problems, but it could also indicate that mothers have increased access to needed health care due to their participation in a home visiting program.

Primary Outcome Measure: For the HomVEE review, an outcome measured through direct observation, direct assessment, or administrative data; or self-reported data collected using a standardized (normed) instrument.

Secondary Outcome Measure: For the HomVEE review, most self-reported data, excluding self-reports based on a standardized (normed) instrument.

Please read Describing Effects for more information on these categories. Only results from studies that meet the standards for the high or moderate ratings are included above.

Criteria Established by the Department of Health and Human Services

Information Based on Comprehensive Review of All High- and Moderate-Impact Studies for this Model
High- or moderate-quality impact study? Yes
Across high- or moderate-quality studies, favorable impacts in…
 
   at least two outcome domains within one sample
 
   OR
 
   the same domain for at least two non-overlapping samples?
Yes
Favorable impacts on full sample? Yes
Any favorable impacts on outcome measures sustained at least 12 months after program enrollment?a Yes
One or more favorable, statistically significant impact reported in a peer-reviewed journal?a Yes

aThis information is reported for all models, but the requirements for sustained findings and inclusion in a peer-reviewed journal only apply to models for which all findings are from randomized controlled trials.
