Pace U, et al. - The present work was performed to examine, from a longitudinal perspective, the relationship between parental (both maternal and paternal) psychological control, perceived peer support, and negative eating attitudes and behaviors, focusing on the moderating role that perceived peer support could play in the relationship between parental psychological control in early adolescence and negative eating attitudes and behaviors in late adolescence. As per regression analyses, negative eating attitudes and behaviors in late adolescence were positively predicted with paternal, but not maternal, achievement-oriented psychological control during early adolescence, however, perceived peer support negatively predicted negative eating attitudes and behaviors. In addition findings revealed a moderator effect of perceived peer support in the relationship between father's psychological control and negative eating attitudes and behaviors, such that at higher levels of paternal achievement-oriented psychological control, negative eating attitudes and behaviors tended to be higher when perceived peer support was low and to be lower when perceived peer support was high.
