The Social Security Administration does not like this impairment as the basis for awarding benefits simply because they believe that the disorder is subjective in nature. Personality disorders are very common. Assessing the severity of a personality disorder comes down to a doctor or psychologist rating the level of impairment as mild, moderate, or severe. A person with a severe personality disorder cannot maintain long-term, healthy relationships with anyone, including their own doctor or psychologist. So what happens with these cases is that because many people with these disorders are obnoxious, unpleasant, and disagreeable, it is difficult to get medical sources, including their own doctors to respond in a favorable manner. History has shown that the most effective use of personality disorders in a disability case turns out to be when the personality disorder is used as a secondary mental impairment as opposed to the primary impairment. In other words a personality disorder may make it difficult for a person to work closely with others, difficult to accept close supervision, difficult to work without close supervision, difficult to do complex work, difficult to tolerate stress, and lastly it may be next to impossible for this person to work closely with the general public.
