Researchers have shown that parenting practices are important in self‐control theory. The purpose of the present study was to examine the link between parental low self‐control, low self‐control, and delinquency. Using a national probability sample and structural equation modeling, the present study showed that parental low self‐control has a link with child low self‐control and that low self‐control does have a link with delinquency. Another structural equation model showed that self‐control mediated the link between parental low self‐control and delinquency. The theoretical implications are discussed.
