Trauma is associated with alterations in cortisol activity and reactivity that may vary in relationship to development, time, predisposition, personality, the nature of a traumatic event, and other circumstances. This article reviews existing research findings related to cortisol in laboratory, general stress, and traumatic conditions. We discuss variables that may influence cortisol activity and reactivity in an effort to discover what is known and what still needs to be learned about cortisol levels in youth exposed to traumas. The extant literature points to a number of potentially negative physical, emotional, and behavioral outcomes of altered cortisol reactivity, which suggests a clear need for early and effective interventions. Furthermore, research has often provided mixed findings from relatively small samples of youth. Improving the understanding of cortisol activity and reactivity in children and adolescents will necessitate examining large samples of different developmental age groups across time.
