All participants were interviewed with the Semi-Structured Assessment for the Genetics of Alcoholism (SSAGA), a comprehensive diagnostic interview with documented reliability and validity (Bucholz et al., 1994; Hesselbrock et al., 1999). The SSAGA comprehensively assesses symptoms and diagnoses of AUD and related disorders (i.e., substance use disorders, mood disorders, antisocial personality, eating disorders, anxiety disorders). COGA is comprised of three waves that use three versions of the SSAGA - the SSAGA-I, SSAGA-II, and SSAGA-IV. Participants were ascertained from across COGA waves and thus were administered at least one version of the SSAGA. Data in this study was from participant’s most recent SSAGA / COGA assessment. The number of COGA waves that participants came in for varies across the sample. Thus, all variables used were lifetime endorsement across COGA waves and SSAGA versions. Outcome variables were help-seeking behaviors and treatment utilization while generation and sex were the main predictor variables. Other demographic variables were treated as covariates (see below).
