Study Notes

Trauma & Stressor-Related Disorders are caused by catastrophic or aversive life events.
They cause more impairment than expected.
Variability exists in how individuals respond to events.

Post-traumatic Stress Disorder (PTSD)

PTSD is categorized by exposure to a traumatic event involving actual or threatened death or serious injury to self or others.
Most common traumatic events are interpersonal, such as sexual assault, physical assault/abuse, combat, torture, and genocide.
Less common sources of PTSD involve natural environmental events, such as floods and earthquakes.
PTSD is associated with four symptom clusters: Intrusion symptoms, Avoidance of trauma-related stimuli, Negative alterations in cognitions & mood, and Marked alterations in arousal and reactivity.

Criterion A: Exposure to traumatic event

Interpersonal trauma is the most common cause of PTSD.
Individuals struggling with PTSD often have difficulty accepting the fact that others would hurt them.

Criterion B: Intrusion symptoms

Intrusion symptoms include memories, images, dreams, and nightmares related to the event (not always the exact event) that often contain common themes.
Flashbacks are common among combat victims.
Images can involve dissociation.
Intrusive symptoms are often cued by trauma stimuli.
Physiological reactivity and physiological distress to trauma cues also occur.

Avoidance occurs cognitively and environmentally.

Criterion D: Negative alterations in cognitions & mood

Individuals may develop exaggerated beliefs about themselves and the world.
Persistent negative emotions, detachment, and an inability to feel pleasure (emotional numbing) can occur.

Criterion E: Marked alterations in arousal and reactivity

Symptoms include hypervigilance, startle response, concentration problems, sleep disturbance, irritability, and self-destructive actions.
Individuals may try to protect themselves in ways that are not safe, such as driving fast after a car accident under the belief that they are a “less likely to hit a moving target”.

Treatment of PTSD

Avoidance or attempts to avoid trauma-related stimuli is common.
Biological treatments include SSRIs, such as Paroxetine, which may increase neurogenesis.
Trauma-focused therapy is considered the gold standard for PTSD treatment.
Prevalence rates of PTSD vary geographically, with the USA at 8.7% and Asia at 1%.
Common events that lead to PTSD in civilians include rape, assault, emergency work, and motor vehicle accidents (MVA).
Common events related to combat include captivity, torture, and genocide.
PTSD can occur at any age, but is less common in older individuals.
Females are more likely to be at risk for PTSD than males, possibly due to a higher incidence of traumatic events in women.
Some argue that women are more likely to report their distress.
Men may manifest trauma in different ways, such as through anger.
The recovery rate for PTSD is 50% within 3 months, but declines after that time.
The incidence rate of PTSD also falls off at a slow rate.
After 2 years, the prognosis for recovery is guarded and individuals may continue to experience significant symptoms.

Controversies of PTSD

The definition of a traumatic event has evolved over time, leading to a broad vs narrow definition debate.
The broad definition of trauma exposure increased from 68% to 89%.
The DSM-5 introduced a requirement for a threat to life or serious injury for events to qualify as trauma, with additional criteria for specific populations.
The nonspecificity of PTSD symptoms creates an overlap with other disorders, such as depression.
Legal issues related to PTSD include questionable/unsubstantiated claims, reliance on self-report, and the assumption that symptoms are caused by the event.
The debate about whether "traumatic events" should be eliminated from the PTSD criteria is ongoing.
Second-hand events, such as hearing about the death or severe injury of a close person, could constitute trauma.

Complex PTSD (C-PTSD)

C-PTSD is not included in the DSM-5, but is listed in the ICD-11.
C-PTSD involves prolonged or chronic exposure to trauma that shapes an individual’s sense of self and disrupts self-organization.
Childhood abuse is the most common cause of C-PTSD.
It has the highest levels of comorbidity with depression and anxiety.
Individuals with C-PTSD demonstrate the lowest levels of psychological well-being.

Diagnosis Criteria of the ICD-11 for C-PTSD

The criteria for C-PTSD include the PTSD criteria + 3 other symptom clusters:
Affect dysregulation- Individuals often have difficulty expressing emotions due to limited exposure to emotional regulation strategies in childhood.
Negative self-concept- Individuals may experience shame and self-hatred.
Disturbances in relationships - Individuals may struggle with relationships due to their experiences with abuse.
The intergenerational transmission of C-PTSD can occur when individuals who have experienced trauma are unable to provide love and support to their children.

Case Study: Residential School Trauma

The cultural clash between Indigenous and Western cultures led to the harmful policies and practices of residential schools.
Differences in cultural perspectives on human nature, relationship to the environment, and cultural practices contributed to the negative impact of residential schools on Indigenous communities.
The impact of residential schools on Indigenous survivors include emotional suppression, numbness, lack of emotional awareness, difficulty expressing emotions verbally, difficulty modulating thoughts, emotions, and behaviors, impulsive violence, socio-cultural shame, and attraction to alcohol and drug use to numb pain.

PTSD vs C-PTSD

While both PTSD and C-PTSD involve exposure to a traumatic event, C-PTSD presents with additional symptom clusters:
- Affect dysregulation
- Negative self-concept
- Disturbances in relationships
The intergenerational transmission of trauma is highly relevant when examining the impact of C-PTSD on Indigenous communities:
- Individuals who are traumatized may be less able to care for their children, resulting in intergenerational cycles of trauma.
- The normalization of abuse through generations can perpetuate harmful behaviors.
Western approaches to trauma do not always consider cultural differences and differences in cultural practices and beliefs.
Legal approaches to violence and abuse in Western society often focus on punishment and isolation, which can perpetuate trauma by creating a disconnect between individuals and their communities.
The treatment philosophy for C-PTSD requires a nuanced understanding of cultural perspectives and the impact of trauma on individuals and communities.

Criterion F: Impairment or Distress

Impairment is a significant factor in the diagnosis of PTSD.
Initially, 50-60% of men who served in combat experienced PTSD, but only 17% are now substantially impaired by it.

Clinical Picture

Prevalence rates of PTSD in the USA are 8.7%, with a point prevalence determined by questionnaires, while 3.5% meet the diagnostic criteria.
The text does not mention prevalence rates for gender.
The impact of trauma is complex and varies depending on individual susceptibility and the toxicity of the event.
While a Criterion A1 event is necessary for a PTSD diagnosis, it is not a sufficient condition.
