title: Borderline: a concept analysis.
abstract: An examination of the literature concerning the borderline reveals that different authors, using different concepts of the borderline state, are describing different patient groups. Related to the background of the generally accepted psychiatric nosological classification, three borderline concepts are clearly discernible: (1) borderline equated with a forme fruste of schizoprenia, (2) borderline equated with a general category of personality disorder (psychopathy) and (3) borderline equated with a special form of personality disorder.
