The Influence of Maternal Age, Employment Status, and Parenthood Status on Children's Cognitive Development

United States, Brazil, Cameroon2,355 participantsStarted 1988-02-17

Plain-language summary

Research and theory tend to agree when suggesting that certain activities done by mothers have both immediate and delayed consequences for children's mental development in the first years of life. The everyday interaction between an infant and a caregiver can be broken down into many categories. There are data linking both of these types of interaction to the mental development of children. The study will focus on the extent to which maternal characteristics (age, employment status, parenthood status, and birth order of the child) influence the relation between maternal social and didactic caregiving and the social and mental development of children. Mother-infant interaction will be observed when the infants are 5 months old. When the children are 20 months old, measures of toddler function (e.g., ability to play and language development) and maternal behavior (e.g., encouragement of attention to the environment and I.Q.) will be obtained. When the children are 48 months old, researchers will measure preschooler psychosocial functioning (e.g., I.Q., cognitive and social competencies) and maternal behavior (e.g., "scaffolding"). Understanding the relation between children's experiences as infants, toddlers, and preschoolers and their eventual intellectual and social functioning is an essential part of normal developmental research.\<TAB\>

* 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.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
