Validity and reliability of the Chinese version of the Lubeck Alcohol Withdrawal Risk Scale
Objective:To evaluate the validity and reliability of the Chinese version of the Lubeck Alcohol Withdrawal Risk Scale(C-LARS).Methods:Referring to previous literature and clinical expert opinions using the Delphi method,a C-LARS was established through translation and back-translation.Principal component analysis was used to evaluate the structural validity of C-LARS,and the maximum variance method was used to calculate factors and factor loadings to evaluate the structural validity of C-LARS.The severity of alcohol withdrawal syn-drome in patients was evaluated using the the Alcohol Withdrawal Scale(AWS),and the criterion validity of C-LARS was evaluated by calculating the correlation coefficient between AWS and C-LARS.Results:The internal correlation coefficient(ICC)of the evaluation factors was 0.972,and the total Cronbach α coefficient was 0.938.Factor analysis and ROC analysis showed that a C-LARS score of ≥ 3 could predict the occurrence of mild alcohol withdrawal syndrome,with sensitivity and specificity of 0.945 and 0.899,respectively.The C-LARS scores of ≥ 5 could predict the occurrence of moderate alcohol withdrawal syndrome,with sensitivity and specificity of 0.910 and 0.905,respectively.The C-LARS scores of≥7 could predict the occurrence of severe alcohol with-drawal syndrome within 12 hours,the sensitivity and specificity were 0.990 and 0.877,respectively.Conclusion:The C-LARS has good validity and reliability,which could be used as a tool to assess the incidence and severity of alcohol withdrawal syndrome within 12 hours after visit.
