Information about the presence/absence of alcohol use disorders, drug use disorders, mood disorders, SA, and conduct disorder and antisocial personality disorder among parents were obtained with the adult version of the Semi-Structured Assessment for the Genetics of Alcoholism, SSAGA (Bucholz et al., 1994). Diagnostic sections of the SSAGA have been intensively studied and show solid reliability (Bucholz et al., 1994; Bucholz et al., 1995; Kramer et al., 2009) and validity (Hesselbrock, Easton, Bucholz et al., 1999). A child/adolescent version of the SSAGA was administered to children ages 17 and younger (Kuperman, Schlosser, Kramer et al., 2001). This youth version was primarily based on the adult SSAGA, but used age-appropriate language. The various diagnostic sections of the child/adolescent version are reliable, with kappa coefficients averaging 0.72 (Kuperman, Schlosser, Kramer et al., 2001). An abbreviated version of the SSAGA, the Family History Module (Rice, Reich, Bucholz et al., 1995), was administered to obtain data from one parent about the other when one of the parents was not available for interview. This abbreviated interview has demonstrated reliability (Rice, Reich, Bucholz et al., 1995)
