Elkind’s (1967) theory of adolescent egocentrism proposes two distinct, but related, constructs – the imaginary audience and the personal fable. A corollary to the imaginary audience, the personal fable (PF) yields a sense of invulnerability and speciality commonly associated with behavioral risk-taking. When regarded as a developmental phenomenon, risk-taking is thought to be the result of cognitive immaturity. However, few adolescent health programs address the egocentric dimension of decision making. We believe that a valid and reliable measure of PF would aid assessment of risk-taking potential and inform preventive interventions. The present paper reports the results of a newly constructed measure of PF and its relation to risk-taking behavior. The following three hypotheses were tested using data from an availability sample of 119 middle school students: 1. PF scores will increase with age; 2. males will score higher than females on the invulnerability dimension of PF; and 3. PF and risk-taking will be positively correlated. As predicted, PF scores increased significantly across the age range studied. Of the two PF dimensions, only invulnerability significantly varied across grades. Males reported significantly higher invulnerability scores than females, and PF and risk-taking were positively correlated. Suggestions for the implementation of this new and, arguably, reliable and valid scale are presented.
