Abstract
Various complex personality disorders are found in eating disorder. Many impulsive behaviors are observed in cases complicated with borderline personality disorder, and their prognostic course is tended to be delayed. In this paper. we followed up the progress of symptoms in 2 cases with eating disorder for approximately 6 years, and carried out Szondi test which is one of the psychological tests using the projective technique for evaluating drive variations. The treatment of symptoms in these 2 cases had been delayed, and the pathology of borderline personality disorder was observed after 6 years. Many variations of clinical symptoms were obtained by Szondi test, and the characteristics of borderline personality disorder such as elevation of drive-excitement, antisocial tendency and anxiety about abandonment were also evaluated by Szondi test. It was considered that Szondi test should be utilized in the prognostic research because it is useful for evaluating the drive risk in various diseases.
