It specifies criteria such as exposure to trauma, intrusion symptoms, avoidance behaviors, and emotional disturbances, along with required durations and effects on functioning. Additional disorders like reactive attachment disorder and disinhibited social engagement disorder are also addressed, highlighting their unique characteristics and associated features.
