Advances in assessment: The differential diagnosis of dissociative identity disorder and schizophrenia

Marlene Steinberg and Harold D. Siegel

Dissociative disorders are characterized by ‘a disruption in the usually integrated functions of consciousness, memory, identity or perception of the environment’ (DSM-IV, American Psychiatric Association, 1994). Considered post-traumatic syndromes, the dissociative symptoms and disorders are more common than previously recognized. Extensive research over the past several decades has established: (1) that dissociative identity disorder (DID) frequently goes unrecognized for several years while a person seeks treatment (Bliss, Larson and Nakashima, 1983; Coons, 1984; Gast et al., 2001; Kluft, 1985a, 1985b, 1987, 1988, 1995; Putnam et al., 1986; Ross and Norton, 1988; Şar et al., 2000; Steinberg, 1995; Steinberg and Schnall, 2001), (2) the frequent misdiagnoses of individuals with DID as having schizophrenia or other psychotic disorders, affective disorders, or solely a substance abuse disorder or personality disorder (Aderibigbe, Block and Walker, 2001; Allen, 1995; Bliss and Jeppen, 1985; Boon and Draijer, 1991, 1993; Chu, 1996; Coons, 1984; Ellason and Ross, 1997; Gast et al., 2001; Goodwin, 1988; Graves, 1989; Kluft, 1987, 1995; Nijenhuis et al., 1997; Putnam et al., 1986; Ray and Faith, 1995; Ross and Norton, 1988; Şar et al., 2000; Spiegel, 1993; Steinberg, 1995; Steinberg et al., 1994; Steinberg and Schnall, 2001; Vanderlinden et al., 1991; Van der Hart, 1993) and (3) the relatively common incidence of DID in outpatients and inpatients (prevalence rates ranging between 1% and 10% for DID) (Bliss and Jeppen, 1985; Boon and Draijer, 1999; Graves, 1989; Gast et al., 2001; Şar et al., 2000; Vanderlinden et al., 1991). In addition, dissociative symptoms, when specifically evaluated, occur commonly among the general population. For example, 10% of 1008 adults in a non-clinical population suffered from recurrent depersonalization or derealization experiences resulting in dysfunction or distress (Aderibigbe, Block and Walker, 2001).
