In this first data collection wave, 9325 adults aged 18 or older, and 1333 children aged 6–17 in 2246 families were assessed. Interviews occurred from 1991 to 1999 (most from 1991 to 1996). Participants were administered the SSAGA in person, although telephone assessments were conducted when transportation difficulties or distance precluded an in‐person visit. 11 Tables 2 (adults) and 3 (children) summarize the participant characteristics, separately for the probands, their relatives, and participants in comparison families.
