<unk>  in the DSM was first listed as a separate diagnosis in version III (1980). In the DSM-IV (1994), it was replaced by "Identity problem", which was not defined as a mental disorder per se, but was listed in a chapter containing problems that might be a focus of clinical attention.<unk>  was 'downgraded' to Identity problem as research indicated that distress over one's identity is so common that it might very well be considered part of the normality. In practice, if a person's distress persisted or worsened, an Identity problem would often be succeeded by a diagnosis of an actual disorder, such as a mood disorder or borderline personality disorder. In DSM-5 (2013), Identity problem was removed.
