A model linking 3 perceived support variables, namely, level of support, quality of support (unconditional or conditional), and hope about future support, to false self behavior (acting in ways that are not the ''real me'') was hypothesized. Both parent and peer support were examined. The best fitting model for the parent and peer data revealed that perceived quality and level of parent support predict hope about future parent support, which in turn predicts false self behavior. Adolescents' motives for engaging in false self behavior were also examined. Those whose reported motives were hypothesized to be the most clinically debilitating (devaluation of the self) reported the most negative outcomes (depressed affect, low self-worth, hopelessness, and less knowledge of the true self). In contrast, adolescents citing the developmentally normative motive of role experimentation reported the most positive affect, highest self-worth, greatest hopefulness, and most knowledge of true self. Those reporting that they engaged in false self behavior to please, impress, or win the approval of parents and peers had intermediate scores on the depression, self-worth, hope, and knowledge of true self measures. Discussion focused on the potential causes and consequences of false self behavior.
