The study of personality development has seen significant advances in the last two decades. For many years, youth and adult individual differences were studied from separate theoretical standpoints. However, more recent research has indicated that teenagers display personality traits in many of the same ways as adults. These personality traits are moderately stable throughout the life course, but there are important developmental shifts in their expression, structure, and maturation, especially in adolescence. This has resulted in an effort to study youth personality “in its own right” (Tackett, Kushner, De Fruyt, & Mervielde, 2013). Early personality associations with important lifelong outcomes including academic achievement, mental health, and interpersonal relationships further underscore the importance of studying traits in youth. Here we discuss current consensus and controversy on adolescent personality and highlight foundational research on the topic.
