Dissociative disorders among alcohol-dependent inpatients.
The aim of this study was to determine the prevalence of dissociative disorders among inpatients with alcohol dependency. The Dissociative Experiences Scale was used to screen 111 alcohol-dependent patients consecutively admitted to the inpatient unit of a dependency treatment center. Subgroups of 29 patients who scored 30.0 or above and 25 patients who scored below 10.0 were then evaluated with the Dissociative Disorders Interview Schedule and the Structured Interview for DSM-IV Dissociative Disorders. The interviewers were blind to the Dissociative Experiences Scale scores. Of the 54 patients evaluated, 10 (9.0% of the original 111) patients had a dissociative disorder. A considerable number of the remaining patients reported a high level of dissociative experiences. Among the dissociative disorder group, nine patients had dissociative disorder not otherwise specified and one patient had depersonalization disorder. Female gender, younger age, history of suicide attempt, childhood emotional and sexual abuse, and neglect were more frequent in the dissociative disorder group than among non-dissociative patients. The dissociative disorder group also had somatization disorder, borderline personality disorder, and lifetime major depression more frequently. For 9 of the 10 dissociative patients, dissociative symptoms started before the onset of alcohol use. Although the probability of having a comorbid dissociative disorder was not higher among alcohol-dependent inpatients than among the general psychiatric inpatients, the dissociative subgroup had distinct features. Many patients without a dissociative disorder diagnosis (predominantly men) provided hints of subtle dissociative psychopathology. Implications of comorbid dissociative disorders and dissociative experiences on prevention and treatment of alcohol dependency and the importance of gender-specific characteristics in this relationship require further study.
