Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) Disorders Practice Exam

Disinhibited Social Engagement Disorder is characterized specifically by behaviors that involve overly familiar or physical interaction with strangers. This can manifest as a child approaching unfamiliar adults without hesitation, which indicates a lack of appropriate social boundaries. The key feature of this disorder is the child's extreme openness to engaging with strangers, demonstrating a disinhibited pattern that contrasts with typical cautious behavior exhibited in social situations with unfamiliar individuals.

In this context, emotional withdrawal from primary caregivers reflects a different issue, particularly often associated with disorders like Reactive Attachment Disorder, where children show a lack of attachment. Recurrent distressing dreams are symptoms more aligned with sleep disorders or anxiety-related issues, and avoidance of social interactions relates to social anxiety or other avoidance disorders. Thus, the behavior of overly familiar interaction with strangers distinctly encapsulates the essence of Disinhibited Social Engagement Disorder.
