Instructions for Twins Who Are Parents


Welcome to the study of twins who are parents! We are interested in learning more about social relationships in families in which twins (identical and fraternal) are married and have children. If one twin has children and the other twin does not, only the twin without children can answer these questions. If your twin is deceased, but has children, you can fill out the survey, but please be sure to answer the last question at the end of this part of the survey. This study has 3 small parts -- please complete each one and answer as accurately as you can. Please do not discuss your answers with your twin until both of you have finished. Please complete this survey only once. Thank you for your interest.
