Using three datasets, we examined the intervention effects when coupled with the B2K program on children’s EF (assessment: Head-Toes-Knees-Shoulders task; HTKS) and math (assessment: Woodcock-Johnson Applied Problems). In the first dataset, children (n = 78) in two randomly selected B2K schools received the intervention and children (n = 47) in one B2K control school did not. Children were assessed pre- and post-program. In the second dataset, all B2K children received the games and a random sample was studied to assess its impact. Children were assessed pre- and post-program (n = 163) and at a follow-up during the fall of kindergarten (n = 97). Results of these datasets were compared to a longitudinal study using an independent sample that assessed children’s normative development on EF and math from the fall of preschool to spring of kindergarten (N = 430).
Results from the first dataset showed that children in the intervention, compared to the active control group, did significantly better on the HTKS (b = 8.40, p < .001), but there were no significant differences in math. In the second dataset, children gained 16.62 points on the HTKS (SD = 16.64) and 4.29 points in math (SD = 3.51) over the 5-month period (beginning of summer to fall of kindergarten). Using information from the third dataset, these B2K children gained more on average than 12-months of expected normative development on the HTKS (M = 13.39, SD = 16.21) and 6-months on math (M = 2.03, SD = 2.67).
Results suggest that children receiving the self-regulation intervention in tandem with the B2K program improved in EF and math beyond what would be expected by maturation alone. Thus, early self-regulation interventions may be promising ways to offset school-entry disparities that potentially contribute to later health inequities and lower levels of well-being.
