“…The scales are also highly correlated with measures of use from timeline follow-back measures, urine tests, collateral reports, treatment records, and blind psychiatric diagnosis (rho of 0.70 or more; kappa of 0.60 or more). 8,23,24,26,29,30 Confirmatory factor analyses suggest that the GAIN's collection of psychiatric and behavioral problems items vary largely along four dimensions: (1) substance use problems (e.g., abuse, dependence, induced), (2) internalizing problems (e.g., depression, anxiety, trauma, suicide), (3) externalizing problems (e.g., attention deficit, hyperactivity/impulsivity, conduct disorders), and (4) crime and violence (e.g., interpersonal, oral, and physical violence, property crime, drug related crime, violent crime; CFI=0.92, RMSE=0.06). 31 In this paper, we focus only on the non-substance use scales.…”
