Better than average… study applies complex variance modelling to more accurately assess treatment effects of the Head Start program

Road sign that says "average"

When assessing the effectiveness of a large-scale, federally funded program such as Head Start—a program designed to better prepare children ages 3-5 from low-income families for school—it is limited to only look at the Average Treatment Effect given the “considerable systematic heterogeneity within population between individuals.” This study applies complex variance modelling, an extension of multilevel modelling, to capture the variance, as well as the mean, in order to shed…

A study focused on middle-aged and older Americans by Harvard Pop Center postdoctoral fellow Justin Rodgers, faculty members David R. Williams, Ichiro Kawachi, and S V Subramanian, along with their colleague Adolfo G. Cuevas, sheds light on the eight behavioral, biological, and psychological pathways commonly thought to play a  role in the association between stress and health.
