BACKGROUND: Spanking has been linked to multiple maladaptive child outcomes. However, previous research linking spanking with children's executive function skills (EFs; inhibitory control, cognitive flexibility, and working memory) is limited by research designs that do not adequately address selection bias concerns, wherein the participant characteristics potentially differ between those who are spanked versus not spanked.
OBJECTIVE: Using a representative sample of US children aged 5 to 6, this study strengthened the evidence for causal estimates on the link between spanking and subsequent EFs with a matched-group design. Low-frequency spanking and potential moderators (child gender, parent race/ethnicity, parental warmth) were tested to determine if they moderated the link between spanking and EFs. PARTICIPANTS: Data were drawn from the Early Childhood Longitudinal Study, Kindergarten Class of 2010-11 (Ns = 12,750-12,830). To mitigate selection bias, entropy-balanced matching was utilized to match spanked versus not-spanked groups, and lagged dependent variable regression analyses were conducted on the matched sample to predict EFs by spanking group status.
RESULTS: After matching, spanking at age 5 was associated with lower inhibitory control and lower cognitive flexibility at age 6, but was not significantly predictive of later working memory. The association with inhibitory control was observed even for low frequency spanking. However, no evidence of moderation by child gender, parent race/ethnicity, and parental warmth was identified.
CONCLUSIONS: This study provides evidence that spanking is associated with lower executive functioning in children, although the associations varied by different EF domains.
