Trauma- And Stressor-Related Disorders

What Are Trauma and Stressor-Related Disorders?

Trauma and stressor-related disorders are mental health conditions that can develop after experiencing or witnessing highly distressing, frightening, or life-threatening events. These may include abuse, violence, accidents, natural disasters, loss, or other overwhelming experiences. While stress reactions after trauma are common, these disorders involve symptoms that persist over time and significantly affect daily functioning, relationships, emotional wellbeing, and a person’s sense of safety.

What distinguishes trauma- and stressor-related disorders from many other mental health conditions is their direct connection to identifiable traumatic or stressful experiences and the lasting impact these events can have on how a person thinks, feels, and relates to the world around them.

How Common Are Trauma and Stressor-Related Disorders?

Trauma exposure and trauma-related disorders are, unfortunately, common experiences worldwide.

This means that the vast majority of people worldwide will experience at least one potentially traumatic event during their lifetime.

United States Statistics:

Trauma Exposure:

• Lifetime exposure: 70-90% of adults experience at least one traumatic event

Types of Trauma and Stress-Related Disorders

The DSM-5-TR recognises several distinct trauma and stress-related disorders, each with specific diagnostic criteria and characteristics.

Post-Traumatic Stress Disorder (PTSD)

PTSD is the most well-known trauma-related disorder, characterised by persistent symptoms following exposure to actual or threatened death, serious injury, or sexual violence.

Diagnostic Criteria:

• Exposure: Direct experience, witnessing, learning about trauma to close family/friend, or repeated exposure to traumatic details
• Intrusion symptoms: Recurrent memories, nightmares, flashbacks, psychological distress, or physiological reactions to trauma cues
• Avoidance: Persistent avoidance of trauma-related stimuli (thoughts, feelings, reminders)
• Negative alterations in cognition and mood: Inability to remember aspects of trauma, negative beliefs, persistent negative emotions, diminished interest, detachment, inability to experience positive emotions
• Alterations in arousal and reactivity: Irritability, reckless behaviour, hypervigilance, exaggerated startle response, concentration problems, sleep disturbance
• Duration: Symptoms persist for more than one month
• Functional impairment: Significant distress or impairment in functioning

PTSD Specifiers:

• With dissociative symptoms: Depersonalisation or derealisation
• With delayed expression: Full criteria not met until at least 6 months after trauma

Acute Stress Disorder (ASD)

ASD involves similar symptoms to PTSD but occurs within one month of trauma exposure and includes prominent dissociative symptoms.

Diagnostic Criteria:

• Exposure: Same as PTSD
• Symptoms: Nine or more symptoms from five categories:
  • Intrusion symptoms (memories, nightmares, flashbacks, distress, physiological reactions)
  • Negative mood (inability to experience positive emotions)
  • Dissociative symptoms (altered sense of reality, inability to remember aspects of trauma)
  • Avoidance symptoms (efforts to avoid memories, thoughts, feelings, reminders)
  • Arousal symptoms (sleep disturbance, irritability, hypervigilance, concentration problems, exaggerated startle)
• Duration: 3 days to 1 month after trauma exposure
• Functional impairment: Significant distress or impairment

Clinical Significance:

• Predictor of PTSD: 50-80% of people with ASD develop PTSD
• Early intervention target: Opportunity for prevention of chronic PTSD
• Treatment response: Often responds well to early intervention

Adjustment Disorders

Adjustment disorders involve emotional or behavioural symptoms in response to identifiable stressors that don't meet criteria for other mental health disorders.

Diagnostic Criteria:

• Stressor: Identifiable stressor occurring within 3 months of symptom onset
• Symptoms: Emotional or behavioural symptoms that are:
  • Out of proportion to the severity or intensity of the stressor
  • Cause significant distress or impairment in functioning
• Duration: Symptoms don't persist more than 6 months after stressor ends
• Exclusions: Don't meet criteria for other mental disorders, not normal bereavement

Subtypes:

• With depressed mood: Low mood, tearfulness, hopelessness
• With anxiety: Nervousness, worry, jitteriness, separation anxiety
• With mixed anxiety and depressed mood: Combination of both
• With disturbance of conduct: Behavioural problems, violation of rights of others
• With mixed disturbance of emotions and conduct: Both emotional and behavioural symptoms
• Unspecified: Symptoms that don't fit other subtypes

Complex PTSD (ICD-11)

While not in DSM-5-TR, Complex PTSD is recognised in ICD-11 and increasingly acknowledged clinically.

Core PTSD Symptoms:

• Re-experiencing in the here and now
• Avoidance of traumatic reminders
• Persistent sense of current threat

Additional Complex PTSD Symptoms:

• Disturbances in self-organisation:
  • Problems in regulation of emotion
  • Negative self-concept
  • Disturbances in relationships

Typical Causes:

• Prolonged, repeated trauma
• Childhood abuse or neglect
• Captivity or imprisonment
• Genocide or war crimes
• Human trafficking

Other Specified Trauma and Stress-Related Disorder

This category includes presentations that don't meet full criteria for other disorders but cause significant distress or impairment.

Examples:

• Adjustment-like disorders with delayed onset: Symptoms beginning more than 6 months after stressor
• Adjustment-like disorders with prolonged duration: Symptoms lasting more than 6 months
• Ataque de nervios: Culture-specific stress response
• Other cultural syndromes: Culture-bound stress reactions

Unspecified Trauma and Stress-Related Disorder

Used when symptoms don't meet criteria for specific disorders but are clearly related to trauma or stress exposure.

Clinical Applications:

• Emergency settings where full assessment isn't possible
• Presentations that don't fit standard criteria
• When clinician chooses not to specify reasons
