Understanding evaluations of home visitation programs

Area of Science:

• Program Evaluation
• Public Health Interventions
• Social Policy Research

Background:

• Home visitation models are key national programs aimed at improving family and child outcomes.
• Evaluating these complex interventions presents methodological challenges.
• Previous evaluations have varied in rigor and scope, necessitating critical appraisal.

Purpose of the Study:

• To discuss the critical role of program evaluation in both improving interventions and determining their effects.
• To outline key methodological choices in designing rigorous home visiting evaluations.
• To guide policymakers and practitioners in interpreting evaluation findings.

Main Methods:

• Discussion of methodological choices including outcome selection, measurement, study design, and comparison group construction.
• Emphasis on robust data analysis plans, including subgroup analysis.
• Consideration of factors like attrition and generalizability in interpreting results.

Main Results:

• The journal issue presents evaluations of prominent national home visitation models.
• These evaluations, while having strengths and weaknesses, represent some of the better studies in the field.
• Specific measures used in these evaluations are summarized.

Conclusions:

• No single evaluation is perfect; readers must critically assess strengths and weaknesses.
• Methodological rigor in design and analysis is essential for credible findings.
• Careful interpretation considering attrition, outcome importance, and generalizability is vital for effective policy and practice.
