The Philadelphia Human Development Study (PHD) is a NIH-funded longitudinal study on the determinants of early childhood development. In the first interview, we ask respondents about their beliefs regarding children’s developmental milestones. In the second interview, we measure the mother’s investments in her child. In the third interview, we measure child development. We will follow about 960 women from pregnancy to when the children are about 24 months old.

Study Materials:

Below, you can find the electronic survey instruments used in the study. So far, we have developed the survey instruments that are conducted at the time that the participant is enrolled into the study (during the second trimester of pregnancy) and the survey that takes place when the child is nine months old. The surveys were created with Python, which you can download  here.
