Strengthening Causal Estimates for Links Between Spanking and Children's Externalizing Behavior Problems.

Area of Science:

• Developmental Psychology
• Child Psychology
• Behavioral Science

Background:

• Establishing causality in child psychology is challenging when experiments are unethical.
• Previous correlational studies on parental spanking and child behavior are limited by selection factors.

Purpose of the Study:

• To investigate the causal link between parental spanking and children's externalizing behavior problems.
• To approximate causal estimates in the absence of randomized controlled trials.

Main Methods:

• Utilized propensity score matching with lifetime prevalence and recent incidence of spanking.
• Employed lagged dependent variables in a large, nationally representative sample (N=12,112).
• Controlled for sociodemographic, family, cultural characteristics, and initial behavior problems.

Main Results:

• Spanking at age 5 predicted increased externalizing behavior problems at ages 6 and 8.
• These findings remained significant after matching for numerous confounding variables.
• The association suggests spanking predicts a deterioration in child behavior over time.

Conclusions:

• Parental spanking is a predictor of increased externalizing behavior problems in children.
• Advanced statistical methods provide strong evidence for a causal link.
• Findings have implications for parenting interventions and child welfare research.
