Introduction
– Anxiety provides the motivation for
achievement, a necessary force for survival.
– Anxiety is often used interchangeably with the
word stress; however, they are not the same.
– Anxiety may be differentiated from fear in that
the former is an emotional process, whereas
fear is cognitive.

illnesses

environments at risk
– A familial predisposition probably exists

Post-traumatic Stress Disorder
(PTSD)
– Development of characteristic symptoms following
exposure to an extreme traumatic stressor involving a
personal threat to physical integrity or to the physical
integrity of others
– Characteristic symptoms include reexperiencing the
traumatic event, a sustained high level of anxiety or
arousal, or a general numbing of responsiveness.
Intrusive recollections or nightmares of the event are
common.
• Psychosocial theory
– The traumatic experience
•
•
•
•
•
•
Severity and duration of the stressor
Extent of anticipatory preparation before onset
Exposure to death
Numbers affected by life threat
Extent of control over recurrence
Location where trauma was experienced
– The individual
• Degree of ego-strength
• Effectiveness of coping resources
• Presence of preexisting psychopathology
– Outcomes of previous experiences with stress/trauma
– Behavioral tendencies
– Current psychosocial developmental stage
– Demographic factors
– The recovery environment
•
•
•
•
Availability of social supports
Cohesiveness and protectiveness of family and friends
Attitudes of society regarding the experience
Cultural and subcultural influences
• Learning theory
– Negative reinforcement as behavior that leads to a reduction in an
aversive experience, thereby reinforcing and resulting in repetition
of the behavior
– Avoidance behaviors
– Psychic numbing
• Cognitive theory
– A person is vulnerable to post-traumatic stress disorder when
fundamental beliefs are invalidated by experiencing trauma
that cannot be comprehended and when a sense of helplessness and
hopelessness prevails.
• Biological aspects
– It has been suggested that a person who has experienced
previous trauma is more likely to develop symptoms after a
stressful life event.
– Disregulation of the opioid, glutamatergic, noradrenergic,
serotonergic, and neuroendocrine pathways may be involved
in the pathophysiology of PTSD.
• Transactional Model of Stress Adaptation
– The etiology of PTSD is most likely influenced by multiple
factors
