Partial slope coefficient: A slope coefficient that measures the individual impact of an independent variable on a dependent variable while holding other independent variables constant.
It is interesting and surprising that intelligence outweighed parenting in predicting children’s self-control. Intelligence was, in fact, by far the strongest predictor of low self-control: More-intelligent children had more self-control relative to their peers who scored lower on intelligence tests. Paternal low self-control significantly predicted children’s low self-control, but the beta was very small. The only other significant variable is sex,
with boys displaying higher levels of low self-control compared to girls. The model R2 = .225, meaning that the entire set of predictors explained 22.5% of the variance in children’s self-control. Clearly, childhood intelligence is integral in the development of self-control and, ultimately, in the prevention of delinquency and crime.
