Etiology linked to Avoidant Personality Disorder includes:

• A. Genetic predisposition and temperamental predisposition to social avoidance and introversion
• B. Substance abuse
• C. Brain injury
• D. Lack of education

Answer: (A)

The factor best explaining this disorder’s etiology is a blend of inherited vulnerability and an early temperamental tendency toward social withdrawal. There is evidence that AVPD runs in families and that certain temperaments—specifically behavioral inhibition and a predisposition to avoid social interaction—make someone more likely to develop a pattern of intense fear of rejection, self-consciousness, and avoidance that defines the disorder. In other words, genetic factors set the stage, and a prone temperament shapes how those vulnerabilities express themselves in social situations.

While substance abuse, brain injury, or limited education can complicate or worsen many conditions, they are not considered primary causes of Avoidant Personality Disorder. They may co-occur or influence functioning, but they do not fundamentally account for the development of the persistent avoidance and feelings of inadequacy that characterize AVPD.
