Trauma- and stressor-related disorders include which disorders?

• A. PTSD and Acute Stress Disorder
• B. Major Depressive Disorder and Dysthymia
• C. OCD and Hoarding Disorder
• D. Schizophrenia and Schizoaffective Disorder

Answer: (A)

Trauma- and stressor-related disorders are defined by exposure to a traumatic or stressful event that leads to significant distress or impairment. The two disorders that fit this category are PTSD and Acute Stress Disorder because they are specifically linked to experiencing or witnessing a traumatic event, with symptoms such as intrusive memories, avoidance, negative changes in thoughts or mood, and heightened arousal.

Acute Stress Disorder covers similar symptoms to PTSD but occurs in the period shortly after the event (typically from 3 days to 1 month) and may resolve or progress to PTSD if symptoms persist. PTSD involves longer-lasting symptoms that endure well beyond the initial month.

The other disorders listed belong to different diagnostic families: Major Depressive Disorder and Dysthymia are mood disorders; OCD and Hoarding Disorder are obsessive-compulsive and related disorders; and Schizophrenia and Schizoaffective Disorder are schizophrenia spectrum/psychotic disorders. Therefore, PTSD and Acute Stress Disorder are the ones that belong to trauma- and stressor-related disorders.
