“ Therefore, while social phobics and patients with AvPD both avoid out of fear, the social phobic’s fears mainly arise in the clinical context of feeling, or actually being called upon to perform in ways ranging from giving a speech to urinating in a public washroom. In contrast the avoidant’s fears generally arise in the context of interpersonal relationships, the main marker I look for in making the diagnosis of AvPD. ”
