Mediation analysis
Note. ***= p < 0.0001; Each arrow represents a regression model (Baron & Kenny, 1986). A was performed as a linear regression with the following control variables: gender, maternal smoking, maternal mental health, parents’ divorce. B was performed as a logistic regression, involving the same controls. The mediation analysis was performed as a bootstrap, and the parentheses shown are bootstrap CI. Percentage mediated = 19.3***
