Kailyn was recently in a car accident.Ever since,she has been experiencing intrusive thoughts and flashbacks and is having difficulty concentrating in school.
A) Into what DSM-5 category does Kailyn's behavior fit? What specific diagnosis might you give her?
B) Does everyone who is in a car accident develop the same symptoms as Kailyn? Why or why not? Discuss one factor that makes a person more susceptible to these issues.

A) Trauma and stressor-related disorders;specific diagnosis: posttraumatic stress disorder (PTSD)
B) Although some people develop PTSD when exposed to severe stress or emotional trauma,not everyone who does is as susceptible to stress responses.Some examples include the following: biological vulnerability may arise from specific genetic markers,and psychological vulnerability may arise from people who more frequently experience anxious cognitions or pay special attention to traumatic stimuli.In addition,biological differences exist between the sexes: women may be more likely (than men) to have PTSD because of hormonal or neurotransmitter differences;culturally,it is more acceptable for women to express negative emotions,so women may be more likely to have negative thoughts and feelings and may be predisposed to pay more attention to stressful stimuli.
