Diagnostic concordance of DSM-III-R, DSM-IV, and ICD-10 inhalant use disorders

The diagnostic concordance of DSM-III-R, DSM-IV, and ICD-10 inhalant use disorders was assessed using the sample of lifetime inhalant users (n = 76) participating in the DSM-IV Field Trial for Substance Use Disorders. Substantially smaller proportions of lifetime inhalant users met DSM-IV inhalant abuse or dependence criteria than met comparable DSM-III-R or ICD-10 criteria. DSM-III-R and ICD-10 performed similarly, although DSM-III-R tended to be more inclusive vis-à-vis diagnoses of inhalant dependence. Kappa coefficients indicated a moderate degree of concordance between the three nosologies for inhalant use disorder diagnosis rates. Inclusion of possible withdrawal symptomatology criteria (that are not normally included) in the DSM-IV and ICD-10 criteria sets for inhalant dependence exerted little effect on diagnosis rates.
