## ABSTRACT

DSM-I (Diagnostic and Statistical manual. Mental Disorders [1st ed.]) had two large categories for personality disorder classification. The first was “personality disorders” defined as “disorders of psychogenic origin or without clearly defined tangible cause or structural change” (American Psychiatric Association, 1952, p. 7), where structural change implied an organic origin. The other large category that addressed personality disorders was a grouping called “transient situational personality disorders,” a concept that some symptom patterns or behaviors that can be viewed as part of a personality disorder may be the result of symptoms that are present because of a comorbid Axis I disorder or because of a situation so overwhelming to the patient that symptoms or defensive posture is mistaken for a personality disorder (Reich, 2002; Reich, Noyes, Hirschfeld, Coryell, & O’Gorman, 1987). As the situation or comorbid condition remits, then the patient no longer appears to have a personality disorder (Reich & Hoffman, 2004).
