The goal of these videos, Carroll states, is to “take some deep dives into issues of health policy — especially those that touch on social determinants of health and health equity.” And he starts with early childhood programs, which includes education.
Episode 2 took a deeper dive into the results: Do early childhood interventions work? What are the outcomes they improve? Researchers looked at 10 outcome categories, which provided 3,183 total outcomes.
Only 34 (1 percent) of the 3183 outcomes were unfavorable, which Carroll characterizes as “good news. It implies that early childhood intervention almost never makes anything worse.” He allows, as well, for “publication bias.” 29 percent of the outcomes had favorable results. The remainder were null.
And when Carroll reviewed program effects by program approach, one key finding: “The only approach (of the four) that showed a statistically significant effect on overall outcomes was early childhood education.” He notes that “the effect sizes of home visits, parental education and transfers were smaller, and not statistically significant.”
Caroll’s headline: “These results should be shouted from the rooftops.” Want to skip to the punchline? Go to 8:19 of the video.
