One obstacle to the investigation of the clinical course of ASPD and AABS in general population or clinical samples is the development of a standardized instrument that would be suitable for a clinician to use to retrospectively assess the major symptoms and behaviors of ASPD and AABS and their occurrence over time. Schuckit et al.(Schuckit et al., 1993), using a structured personal interview incorporated into the Semi-Structured Assessment for the Genetics of Alcoholism (SSAGA), successfully indexed the clinical course of another set of correlated disorders, alcohol use disorders, based on the age and relative order of appearance of 36 major alcohol-related life events. This approach had the advantage of allowing the recording of the events in an objective and verifiable manner over time in either large general population or high-risk samples. Using this instrument Schuckit and colleagues (Schuckit et al., 1995; Schuckit et al., 1993; Schuckit et al., 2002) reported a high level of similarity in the clinical course of alcohol dependence across various subgroups with alcohol use disorder (e.g., inpatients vs. outpatients, males vs. females, presence vs. absence of
