Trustworthiness Processing and Psychobiological Responses to Natural Disaster-Induced Distress in Adolescents

In this study, we examine the role of trust perceptions on psychological well-being and salivary cortisol levels of adolescents who were exposed to pervasive, noninterpersonal trauma, displacement, and relocation caused by Hurricane Katrina. Compared to demographically matched controls, affected adolescents reported higher perceptions of other people's trustworthiness, decreased externalizing behaviors, increased internalizing behaviors, greater desire for consolation from others, and lower cortisol activity. Follow-up analyses suggested that the relation between hurricane exposure and lower self-esteem might be mediated partly by increased trustworthiness perceptions. These results suggest that adolescents might respond to different types of stressors with varying patterns of distress and the manner in which the stressors alter trust processing might predict the development of internalizing or externalizing behaviors.
