The San Diego Prospective Study (SDPS) is a longitudinal data set that examines multiple characteristics that include many of the social processes and biologically based characteristics discussed above as potentially related to the course of AUDs. The sample involves >400 men who were originally recruited as 18–25 year old healthy males who drank alcohol but were not alcoholic, made up of pairs of sons of alcoholics and controls matched on recent substance use and demography (Schuckit and Gold, 1988). The selection criteria focused on the majority of alcoholics who develop their disorder in their twenties in the absence of severe impulsivity or disinhibition (Finn et al., 2005). The men have been followed ~every 5 years for over 30 years to see how multiple social and biologically-based characteristics from ~age 20 relate to the development and course of drinking patterns and problems over the next three decades (Schuckit, 2009; Schuckit and Gold, 1988; Schuckit and Smith, 2000; Trim et al., 2009). As part of this process, our group earlier examined predictors of AUD onset and course remission data from the SDPS
