“low risk.” An additional group of families was selected from men identified through driving records as having 2 or more drunk-driving convictions and classified as “very high risk.” Sample enrollment occurred over 6 years. A total of 731 females (of 1,461 offspring interviewed) completed at least one interview. For the current analyses, 163 full-sibling pairs, 30 full-sibling trios, and 315 individuals with no female sibling interview data were included – 81% of these women were interviewed at least twice. Of the 511 women who were recruited in the first 3 years and were interviewed at least once, 89% had 2 or more, and 73% had 3 or more follow up interviews. Rates are comparable across EA and AA women. These retention rates are quite good, particularly in light of the high risk nature of the families to which these women belonged.
