This study is an Alcohol Cohort 1 repeatability trial. A total of
500 males and 500 females from the Alcohol Cohort
1 study who returned their questionnaires within the first month were
sent another "white/green" questionnaire in 1991. Their responses
to the two questionnaires could then be compared to check on their
consistency. Of the 1000 subjects, there are 161 complete pairs and 678
single twins.

the Alcohol Cohort 1 study:
