Access to Child Development Project Data
The Child Development Project is committed to a policy of allowing the research community access to data, under conditions that strictly protect the rights and privacy of Child Development Project participants. The research design that has guided Child Development Project data collection over the entire study period requires a restricted-use mechanism for sharing the data with the research community. The restricted-use data policy currently applies to data from study years 1 through 24 and 30.
The rationale for restrictions on data use is based on the level of sensitivity of the data, where “sensitive data” are defined as any data from a research project that may compromise the anonymity or privacy of respondents. During the course of the study, the project staff has followed strict guidelines to maintain the confidentiality of the data as it is processed, and will take all appropriate steps to remove direct and indirect identifying information from shared data files. However, the sensitive nature of the data requires that we systematically safeguard the privacy and anonymity of respondents by establishing a contractual agreement with investigators and institutions requesting the data. The specific contractual conditions are set forth in the Data Use Agreement for Child Development Project.
To further safeguard the privacy and anonymity of respondents, all plans for use of Child Development Project data must address the risk of deductive disclosure — the discerning of a respondent’s identity through knowledge of a combination of characteristics of that individual. Data requests will be reviewed carefully for potential disclosure issues through indirect identifiers. For some combinations of data, it will be necessary to apply statistical disclosure limitation techniques prior to data release. For example, a cross-tabulation of respondent’s race with study site yields a cell with only two cases, with 99 percent of cases in a single cell. Thus, for one of the study sites, individual-level race categories will not be released. These and other potential disclosure limitations will be discussed with the researcher and incorporated to the research plan.
Child Development Project data are released only for research use.
The Instrument Administration History and Data Instruments sections of this website provide a comprehensive listing of the measures available from the Child Development Project and documentation for those measures. Data collected by the Child Development Project will be released for use by the scientific community, for research purposes only, through the restricted-use mechanism described below. Currently, data for both respondent cohorts are available for study years study years 1 through 24 and 30.
Costs Associated with Data Access
To cover the expenses of processing requests, producing and shipping data files and documentation, and administering data use agreements, the Child Development Project Data Center requests payment of a non-refundable fee in the amount of $1,105 per day. Further consultation with Data Center staff is available at this daily rate.
1. Requirement of Investigators and Receiving Institutions
Investigators must meet the following criteria:
- have a PhD or other terminal degree, and
- hold a faculty appointment or other research position at the receiving institution.
Graduate students who wish to use Child Development Project data for dissertation research must apply through their faculty advisors.
Receiving institutions must meet the following criteria:
- be an institution of higher education, a research organization (non-profit), or a government agency,
- have a demonstrated record of using sensitive data according to commonly-accepted standards of research ethics, and
- have established protocols for an Institutional Review Board/Human Subjects Review Committee or equivalent body to review research proposals using sensitive data.
2. Research Proposal
Applicants for Child Development Project restricted data must provide a written description of the research project, including:
- an abstract,
- research questions,
- primary methodology,
- specific measures and study years being requested,
- the types of data from other sources that will be merged with this restricted data file,
- plans for use of the results of the research, including plans for publication, and
- time frame for analysis of the data and data destruction.
3. Sensitive Data Security Plan
Investigators must submit a Sensitive Data Security Plan to the Child Development Project Data Center, outlining the measures that will be taken to ensure that no persons, other than those authorized by the signed agreement, can have access to the contents of the Child Development Project data sets. This data protection plan applies to the data files supplied by the Child Development Project Data Center, as well as any copies made by the research team, and any new data derived from the restricted data. “Derived data” include subsets of cases or variables, as well as numerical or other transformations of variables from the original data. The plan also should include a discussion of the computing environment in which the data will be managed, analyzed, stored, and transmitted among research team members. The investigators must address in detail the security measures that will be implemented for protection of these restricted data.
4. Signed Data Use Agreement
5. Review Board Approval from Receiving Institution
Child Development Project requires that the investigator submit a copy of the document, signed by the receiving institution’s Institutional Review Board, approving the research project and acknowledging the risks of deductive disclosure that require special procedures for handling Child Development Project data. The IRB also must approve the procedures for the secure use and storage of the data as agreed in the Sensitive Data Security Plan. Human Subjects review for Child Development Project data must be in accordance with procedures used for live human subjects; the investigator may not request exemption from review. Child Development Project will release data only for projects that have received approval through expedited or full board review of both the research proposal and the Sensitive Data Security Plan.
