Abstract:

BACKGROUND: The Semi-structured Assessment for Drug Dependence and Alcoholism (SSADDA) was developed to assess substance-use disorders and other psychiatric traits. We translated the SSADDA into Chinese and evaluated its inter-rater reliability and concurrent validity in diagnosing DSM-IV methamphetamine (MA) dependence and DSM-5 MA-use disorder (MUD). METHODS: The sample comprised 231 participants who were interviewed using the Chinese SSADDA and the Mini-International Neuropsychiatric Interview (Chinese MINI) for concurrent validation. Of the 231 participants, 191 were interviewed by two different interviewers two weeks apart. We evaluated the inter-rater reliability and concurrent validity of the diagnoses using percent agreement and Cohen''s kappa coefficient (?). Cohen''s linear weighted kappa was used to assess the reliability of DSM-5 MUD severity. RESULTS: It showed good inter-rater reliability and no significant differences among the DSM-5 MUD (?  =  0.71), DSM-IV MA abuse or dependence (?  =  0.72), and the DSM-IV diagnoses of MA dependence (?  =  0.66) and abuse (?  =  0.68) tested separately. The weighted kappa was 0.67 across the three DSM-5 MUD severity levels. The reliability of each individual diagnostic criterion for DSM-5 MUD ranged from fair to excellent (?  =  0.41-0.80), except for "repeated attempts to quit/control use" (?  =  0.38). The concurrent validity based on MINI-derived diagnoses ranged from good to excellent (?  =  0.65-0.78). CONCLUSIONS: This study shows that the Chinese version of SSADDA has good reliability and validity among Chinese MA users.
