ABSTRACT
This study examined the longitudinal associations of adolescents’ lie-telling and moral evaluations of other-oriented lies told to friends, as well as the potential moderating roles of age and peer influence. Adolescents (N = 818; 11–17 years at T1; Mage = 13.30, 49.80% male) reported how often they told other-oriented lies to their friends, their moral evaluations of other-oriented lies, and their sensitivity to peer influence annually for 3 years. In early adolescence, a bidirectional relationship between moral evaluations and lie-telling was found. Additionally, sensitivity to peer influence was bidirectionally associated with both moral evaluations and lie-telling. In late adolescence, moral evaluations predicted lie-telling frequency, but lie frequency did not predict evaluations. Both moral evaluations and lie-telling predicted sensitivity to peer influence.
