Changes in the identity integration of adolescents in treatment for personality disorders

A renewed interest in identity as one of the core markers of personality disorders has been introduced by the DSM-S Level of Personality Functioning Scale. However, little is known about the utility of the construct of identity in children and adolescents. This study aimed to broaden the knowledge of identity integration as a core component of personality functioning in adolescents. The authors investigated levels of identity integration, as measured by the Severity Indices of Personality Problems (SIPP-11 8; Verheul et al., 2008), in adolescents in both normal (« = 406) and clinical populations (« = 285). Furthermore, changes in levels of identity integration during treatment were investigated in a clinical subsample (« = 76). Levels of identity integration were not associated with age. They were, however, associated with the absence or presence of personality pathology. Most adolescents receiving inpatient psychotherapy gradually changed toward more healthy levels of identity integration; a significant number, however, remained at maladaptive levels of identity functioning after intensive psychotherapy.
