This methodology report provides information on the first wave of the National Survey of Fertility Barriers (NSFB). This nationally representative telephone survey of women age 25-45 was funded by grant R01-HD044144 from the National Institute of Child Health and Development (NICHD) entitled “Infertility: Pathways and Psychological Outcomes.” Professor Lynn K. White was the Principal Investigator for the first two years of the project. Following her retirement, Professor David R. Johnson assumed this role. The survey was conducted between 2004 and 2007 and includes completed interviews with 4,712 women age 25 to 45 and 936 of their partners. The data were collected by the Survey Research Center at The Pennsylvania State University and the Bureau of Sociological Research at the University of Nebraska-Lincoln. The Bureau of Sociological Research is currently in the field re-interviewing the respondents three years after their initial interview. The field work on the second wave is not expected to be completed until the end of 2009. The documentation in this report is directed towards researchers who are interested in conducting analyses of the public release version of these data. The data are being released and are archived with the Population Research Institute at Penn State University. Inquiries about the NSFB should be directed to the study Principal Investigator Professor David R. Johnson at Penn State University (drj10@psu.edu) or to Professor Julia McQuillan, a project investigator at the University of Nebraska (jmcquillan2@unlnotes.unl.edu).
