Invincibility fable: Tool development to measure invincibility

摘要

Invincibility is a phase of social-cognitive development of the adolescent and has been associated with risk behavior involvement. Objective: To determine psychometric properties of the Adolescent Invincibility Tool (AIT). Methods: Reliability was assessed and validity was examined using principal components analysis. Results: Internal consistency was demonstrated with a Cronbach's alpha of .88; factor analysis led to the confirmation of subscales. Criterion validity was validated with similar and opposing measures of invincibility. Discussion: Initial testing suggests that the AIT is a valid and reliable tool for screening invincibility. Further testing is recommended to determine relevance for other populations of youth.
