The data presented here deal with all appropriate members of 2 generations of the SDPS families and are not limited to proband/offspring pairs. Note that some proband data come from the alcohol challenges at average age 23, as well as data from their Time 1 and Time 2 evaluations at average ages of 37 and 42, respectively. Offspring Time 1 and Time 2 data were gathered at average ages of 20 and 26. For each group, Time 1 is that age at which the first SRE was gathered.
