The current study explored the associations between activity-based identity experiences and youth outcomes. Participants were 107 high school students and one parent or guardian of each from three communities in a Northeastern state. Youth completed a measure of activity-based identity experiences (Personally Expressive Activities Questionnaire (PEAQ) [Waterman, A. S. (1990). Personal expressiveness: Philosophical and psychological foundations. "Journal of Mind and Behavior, 11," 47-74]), as well as measures of psychological well-being, substance use, and delinquency. Parents completed the Child Behavior Checklist [Achenbach, T. M. (1991). "Manual for the Child Behavior Checklist/4-18 and 1991 profile." Burlington, VT: University of Vermont Department of Psychiatry]. Together, three identity experiences derived from the PEAQ, personal expressiveness, goal-directed behavior, and flow, were significant predictors of adolescent-reported delinquency and well-being. Goal-directed behavior also uniquely predicted adolescent-reported delinquency and well-being. Suggestions for future research and potential implications for intervention are discussed.
