The added impact of parenting education in early childhood education programs: A meta-analysis

Many early childhood education (ECE) programs seek to enhance parents’ capacities to support their children's development. Using a meta-analytic database of 46 studies of ECE programs that served children age three to five-years-old, we examine the benefits to children's cognitive and pre-academic skills of adding parenting education to ECE programs for children and consider the differential impacts of: 1) parenting education programs of any type; 2) parenting education programs that provided parents with modeling of or opportunities to practice stimulating behaviors and 3) parenting education programs that were delivered through intensive home visiting. The results of the study call into question some general longstanding assertions regarding the benefits of including parenting education in early childhood programs. We find no differences in program impacts between ECE programs that did and did not provide some form of parenting education. We find some suggestive evidence that among ECE programs that provided parenting education, those that provided parents with opportunities to practice parenting skills were associated with greater short-term impacts on children's pre-academic skills. Among ECE programs that provided parenting education, those that did so through one or more home visits a month yielded effect sizes for cognitive outcomes that were significantly larger than programs that provided lower dosages of home visits

Cost-Effectiveness Analysis: A Proposal of New Reporting Standards in Statistical Analysis

Cost-effectiveness analysis (CEA) is a method for evaluating the outcomes and costs of competing strategies designed to improve health, and has been applied to a variety of different scientific fields. Yet, there are inherent complexities in cost estimation and CEA from statistical perspectives (e.g., skewness, bi-dimensionality, and censoring). The incremental cost-effectiveness ratio that represents the additional cost per one unit of outcome gained by a new strategy has served as the most widely accepted methodology in the CEA. In this article, we call for expanded perspectives and reporting standards reflecting a more comprehensive analysis that can elucidate different aspects of available data. Specifically, we propose that mean and median-based incremental cost-effectiveness ratios and average cost-effectiveness ratios be reported together, along with relevant summary and inferential statistics as complementary measures for informed decision making
