A Meta-Analysis of Home Visitor Programs: Moderators of Improvements in Maternal Behavior.
Casady, Angela; Van Egeren, Laurie
A meta-analysis including nine samples of mothers in home visiting programs (N=1,600) examined differences in the effects of home visitor programs on maternal behavior. Although effect sizes varied, programs with more frequent visitation had higher success rates. This dosage effect explained all of the variance in effect sizes. Other significant variables included number of participants, type of administrative organization, and year of study publication. Specifically, larger sample sizes predicted lower effect sizes. University programs were more successful than programs administered by nonprofits or government agencies. Studies conducted more recently had lower effect sizes. However, this last finding reflected the occurrence of less frequent visitation in later studies. The correlation between frequency of visitation and the year of the study was strong.
