Abstract
Aims
Our aim was to adapt the Clinical Institute of Withdrawal Assessment for Alcohol scale (CIWA-Ar) into Estonian and test its reliability and validity.
Methods
A total of 72 patients with alcohol withdrawal syndrome participated in the study. In order to assess the interrater reliability, at first assessment the CIWA-Ar was simultaneously completed by two nurses. In order to assess the sensitivity of the CIWA-Ar to the changes in the severity of the withdrawal syndrome, as well as its correlations to several indices characterizing the subjects’ current condition, the CIWA-Ar, the Clinical Global Impression Severity subscale (CGI-S), the visual analogue scales for the assessment of the general feeling of malaise, anxiety and depression were filled in and the vital signs were measured at inclusion, in 4 h and after the withdrawal syndrome had been resolved.
Results
The intraclass correlation coefficient (ICC) for the Estonian version of the CIWA-Ar total score, used as an indicator of interrater reliability, was excellent. The CIWA-Ar had significant correlations with the psychiatrists’ CGI-S ratings of the severity of the patient’s condition at all assessment points. Significant correlations were also found between CIWA-Ar and patients’ self-ratings, the highest correlations found with self-rated anxiety and general feeling of malaise. CIWA-Ar total score did not correlate with simultaneously measured heart rate, systolic and diastolic blood pressure at the first assessment. At the second assessment, heart rate had a significant correlation with the CIWA-Ar total score.
Conclusion
Our study provides confirmation that the CIWA-Ar tool is well applicable in the Estonian language and culture setting.
