Eligibility Criteria
Inclusion
- INCLUSION CRITERIA:
- All subjects are normal volunteers.
- At initial recruitment, all mothers will be married women living in intact families with healthy, full-term, first-born infants. Most will be living in intact families.
- Prior to inclusion in the sample, basic demographic information will be obtained for all study participants including substitute caregivers but excluding school teachers. Variables include age, race, cultural background, primary language, marital status, SES (as assessed by the Hollingshead Four-Factor Index of Social Status, 1975), and educational level. In addition, for caregivers, information about their experience caring for children and about the peer environment, including the number of children routinely present, their sexes, and their ages, will be obtained.
- To the extent that the adolescent sample diverges from sample criteria with respect to marital status and SES, appropriate controls will be used.
- Subjects in the Argentine-American and Japanese-American project will be selected to represent families high vs low on appropriate measures of acculturation.
- The healthy second born infants of 80 mothers already enrolled in the protocol will also be recruited into the sample at the time of their birth. These infants will be selected to comprise four equal groups based on the gender composition of the sibling dyad: male/male, male/female, female/female, and female/male.
