Invincibility Fable: Tool Development to Measure Invincibility 1

BackgroundInvincibility is a phase of social-cognitive development of the adolescent and has been associated with risk behavior involvement.ObjectiveTo determine psychometric properties of the Adolescent Invincibility Tool (AIT).MethodsReliability was assessed and validity was examined using principal components analysis.ResultsInternal 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.DiscussionInitial 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.
