A rating scale for assessment of alcohol withdrawal psychopathology (AWIP).

For patients in alcohol withdrawal, there are several scales designed to assess physiological disturbances, but there seems to be a lack of scales for assessment of psychopathology. To develop and evaluate a rating scale for psychopathology, items from the Comprehensive Psychopathological Rating Scale (CPRS) were selected, and patients meeting the DSMR-III-R criteria for alcohol dependence (303.90) were rated on these items. The patients were divided into two groups according to the length of time passed since their last period of alcohol consumption. The groups are referred to as the group (n = 53) in early withdrawal, rated daily during 1 week and the group (n = 13) in late withdrawal, rated once a week for 7 weeks. To justify inclusion in the new scale, items had to either indicate psychopathology in at least half of the patients in one of the groups in withdrawal, or be sensitive to changes over time at a 0.1% level of significance. Seventeen items fulfilled one of these criteria. The scale was tested for inter-rater reliability in a new sample of patients (n = 30) in early withdrawal. Inter-rater reliability, as well as internal consistency, was found satisfactory. This new scale, capable of identifying psychopathology and changes over time, may be used alone or together with physiological scales to identify subgroups of patients undergoing withdrawal.
