This is the "white/green" or Alcohol Cohort 1 questionnaire data for cases where both twins received the Canberra questionnaire but only one responded; i.e. the Canberra Singles. As a result, these twins were not originally selected for the Alcohol Cohort 1 study. In 1990, these twins (575 pairs) were sent the white/green questionnaire.

The questionnaire is the same as that for the Alcohol Cohort 1 study:
