The current study examines the effects of prekindergarten quality and quantity on externalizing
behavior problems for children living in non-parental care, compared to other children from
socioeconomically at-risk backgrounds. Data were obtained from the Head Start Impact Study.
Non-parental care was defined as a primary caregiver other than a biological,...
This study examined relations between children’s attention span-persistence in preschool and later school achievement and college completion. Children were drawn from the Colorado Adoption Project using adopted and non-adopted children (N = 430). Results of structural equation modeling indicated that children’s age 4 attention span-persistence significantly predicted math and reading...
The present study examined the efficacy of a self-regulation intervention for children experiencing demographic risk. Utilizing a randomized controlled design, analyses examined if children (N = 276 children in 14 Head Start classrooms; M age = 51.69, SD = 6.55) who participated in an 8-week self-regulation intervention demonstrated greater gains...
Children’s behavioral self-regulation and executive function (EF; including attentional or
cognitive flexibility, working memory, and inhibitory control) are strong predictors of
academic achievement. The present study examined the psychometric properties of a
measure of behavioral self-regulation called the Head-Toes-Knees-Shoulders (HTKS) by
assessing construct validity, including relations to EF measures, and...
PURPOSE—We examined the effects of Positive Action (PA), a school-based social-emotional learning and health promotion program, on the emotional health of predominately low-income and ethnic minority urban youth.
METHODS—The study was a matched-pair, cluster-randomized controlled trial involving 14 Chicago public schools. Outcomes were assessed over a 6-year period of program...
BACKGROUND: School-based social-emotional and character development (SECD) programs can influence not only SECD, but also academic-related outcomes. The purpose of this study was to evaluate the impact of one SECD program, Positive Action (PA), on educational outcomes among low-income, urban youth.
METHODS: The longitudinal study used a matched-pair, cluster-randomized controlled...
This study examined relations among early family risk, children’s behavioral regulation at 54
months and kindergarten, and academic achievement in first grade using data on 1,298 children
from the National Institute of Child Health and Human Development (NICHD) Study of Early
Child Care and Youth Development. Family risk was indexed...
Changes in glacier length reflect the integrated response to local fluctuations in temperature and precipitation, but when do such changes indicate forced climate change, and when do they indicate natural variability? In this study, we simulate the past ~1000 years of glacier length variability across the globe using the 3-stage...
