Diagnosis after an acute psychiatric inpatient stay : how do psychotic and non-psychotic diagnoses relate to the results of psychometric tests of substance abuse?

Abstract

The AUDIT questionnaire indicated scores above cut-off for seven (38.9%) patients with a psychotic disorder, 18 (52.9%) with an affective disorder, six (66.7%) with a substance abuse diagnosis and three (23.1%) with other diagnoses. The DUDIT questionnaire indicated scores above cut-off for six (33.3%) patients with a psychotic disorder, four (11.8%) with an affective disorder, seven (77.8%) with a substance abuse diagnosis and none of the patients with other diagnoses. The sensitivity and specificity of the AUDIT test in this sample were calculated as 0.67 and 0.57 respectively and of the DUDIT test as 0.78 and 0.13 respectively.
