ABC Brain Games Self-Regulation Intervention

The goal of this project is to measure childhood self-regulation targets known to be associated with obesity risk and poor adherence to medical regimens and to assess whether intervening on these mechanisms can improve self-regulation. The investigators will do so in a pre-existing cohort of low-income school-age children.

Poor self-regulation (i.e., inability to harness cognitive, emotional or motivational resources to achieve goals) contributes to a number of unhealthy behaviors across the life course, including overeating, a lack of physical activity, smoking, alcoholism and substance abuse that are linked to poor long-term health. The self-regulation processes that generate the desire for such substances or that make it difficult to engage in healthy habits are theorized to begin very early in the lifespan. Targeting early self-regulation profiles that signal risk for engaging in unhealthy behaviors would allow more effective intervention. The investigators will assess self-regulation during pre-adolescence, a critical transition when children gain responsibility for managing their health choices and self-regulation becomes increasingly associated with health outcomes. Obesity is a complex health issue with early-emerging biological and behavioral precursors that are related to self-regulation; as such it is a good model for understanding a broad range of health conditions that require active self-management. Childhood obesity is also an ongoing public health crisis, with almost 25% of children overweight by age 4 years (35% by school-age). The goal of this study is to measure childhood self-regulation targets known to be associated with obesity risk and poor adherence to medical regimens and to assess whether intervening on these mechanisms can improve self-regulation. The investigators will do so in a cohort of children with a high rate of obesity who have been extensively phenotyped for bio-behavioral self-regulation and obesity risk factors from early childhood.

The aim is to, in low-income school-age children from extant cohorts, develop and field-test interventions designed to address self-regulation targets using a Multiphase Optimization Strategy (MOST) design to detect intervention effectiveness and child or family factors (e.g., maternal education, family stress, early childhood eating or stress regulation pattern) that may moderate intervention effects. The investigators hypothesize that our interventions will cause change in the self-regulation targets most closely related to the intervention components (e.g., EF-focused intervention will change EF targets).
