Sixty-three children and families (54% female, 92% Caucasian, 57% total annual income above $60,000) from a longitudinal study of 124 participants from central Pennsylvania had complete data at the 24-month visit and teacher reports during the fall of kindergarten. During the 24-month visit, families completed tasks in the lab that ranged in threat levels (Buss & Goldsmith, 2000). Coders rated amount of child withdrawal and how often parents displayed comfort and control in each task. During the fall of kindergarten, teachers completed the Teacher Observation of Classroom Adaptation-Revised Questionnaire.
Examining toddler withdrawal as a predictor of school maladjustment, we found that low levels of withdrawal across tasks predicted higher levels of classroom maladjustment, β=-0.002, t(63)=-2.28, p=0.03. We then included parental comfort and control separately as moderators using bootstrapped linear regressions. We found a marginal moderation of comfort, β=0.004, t(63)=1.92, p=0.06, where the relation between low withdrawal and maladjustment was only significant when parents were low in comfort, β=-0.004, t(63)=-2.16, p=0.035. Parental control did not moderate the model, but instead predicted maladjustment over low withdrawal β=-0.25, t(63)=-2.04, p=0.05.
These results suggest that children low in withdrawal, or high in approach, are at risk for externalizing behaviors in kindergarten. This effect is particularly strong when parents are low in comfort and control suggesting that these children benefit from structured parenting that is also sensitive to their needs. Interventions addressing school readiness should consider child characteristics and target parenting as a mechanism for better adjustment outcomes.
