Background:
Measurement of craving is an important component in the investigation of the etiology and clinical pictures of alcoholism and dependence of other substances in different cultures. The aim of this study was to develop a Chinese version of the Yale-Brown Obsessive Compulsive Scale for heavy drinking (YBOCS-hd-C), the instrument most frequently used in assessing the severity of alcohol craving in Taiwan.
Methods:
Four hundred twenty Han Chinese (220 with alcohol use disorders) and 218 Bunun aborigines (150 with alcohol use disorders) in Taiwan were interviewed by mental health professionals with the YBOCS-hd-C and a Chinese version of the World Health Organization Schedules for Clinical Assessment in Neuropsychiatry to establish the psychiatric diagnosis. Validity and reliability of the YBOCS-hd-C were examined.
Results:
The YBOCS-hd-C was found to have acceptable interrater reliability (intraclass correlation, 0.89-0.96), internal consistency (Cronbach's alpha = 0.99), construct validity, concurrent validity, and cross-cultural validity. The correlations between 10 items of the YBOCS-hd-C and 11 items of the World Health Organization Schedules for Clinical Assessment in Neuropsychiatry adjusted for age, gender, and ethnicity ranged from 0.39 to 1.00. The YBOCS-hd-C also discriminated effectively among individuals with alcohol dependence, alcohol abusers, and normal drinkers.
Conclusions:
This study demonstrated that the YBOCS-hd-C is a reliable and valid instrument for assessing the extent of craving for alcohol in Taiwanese Han and Bunun individuals.
