Pennsylvania Longitudinal Study of Parents and Children and Pennsylvania Twin Registry

Multiple-birth families are an important resource for researchers interested in investigating how social and genetic influences work together to influence health-related behaviors.

The Pennsylvania Longitudinal Study of Parents and Children (PALSPAC) study examine the lives of twins and their families.

All the information in the study is confidential. Many families find that participating in research is interesting, gives insight into their children's development, and provides an opportunity to contribute to what we know about social and health behaviors.

PALSPAC is approved by the Penn State University Institutional Review Board and provides financial compensation to participants.
