Using cluster analysis of Adolescent Time Attitude Scale (ATAS) scores in a sample of 300 adolescents (M age = 16 years; SD = 1.25; 60% male; 41% European American; 25.3% Asian American; 11% African American; 10.3% Latino), the authors identified five time attitude profiles based on positive and negative attitudes toward the past, present, and future. Four of the profiles identified in the present study were conceptually similar to profiles that emerged in a study in a German sample. Adolescents with profiles characterized by higher positive attitudes than negative attitudes (i.e., Positive, Optimistic, and Balanced) reported more favorable educational and psychological outcomes than did adolescents with profiles marked by higher negative attitudes (i.e., Negative and Pessimistic). These findings provide support for the generalizability of time attitude profiles and the pattern of relationships between ATAS profiles and other constructs.
