Susceptibility, Resilience, and Trajectories
Nearly everyone experiences a highly stressful or traumatic event during their lifetime. However, individual responses to such events vary widely from person to person. Some people respond with symptoms of anxiety, depression, acute stress, or posttraumatic stress disorder, yet others experience minimal or no psychiatric symptoms after trauma. What makes one person more susceptible and another more resilient to the negative effects of trauma? What are the different adaptive trajectories of trauma survivors and what determines their trajectory? These are some of the questions that are examined in this chapter, which focuses on what is currently known about resilience to stress. The chapter is divided into five sections: definition, prevalence, and measurement of resilience; longitudinal studies on trajectories after trauma exposures; research on factors that are predictive of resilience and different trajectories; interventions that have been developed to increase resilience; and discussion about future directions for research on resilience.
