PIN Data or Specimen Use Request Process

1. A request for access to PIN data or specimens requires collaboration with one of the PIN Study's co-investigators (see Research Team). A preliminary discussion about the research topic and what data or specimens would be required must take place with an investigator before proceeding to the next steps.
2. An Data/Specimen Proposal Form must be submitted via email to Anna Maria Siega-Riz. 
3. The request will be evaluated by the investigators on the following basis:
   
   • scientific merit
   • sufficient power within the PIN data/specimens to address the aims
   • likelihood that the effort will be completed through publication
   • logistics and time required to assemble the analysis file, based on the estimated programmer prep time
   • amount of support required to complete the analysis/publication
     
   • whether specimens are available for the requested purpose
4. You will be notified if the research is approved by the study team. If it is approved you will be instructed to complete a Data Use Agreement Form, which provides guidance on use and security of the data, have the collaborating study investigator sign it, and mail it to Anna Maria Siega-Riz at CB #8120. (Data Use Agreement is in MS Word format.)
5. Develop an electronic list of variables, by their source file, so that an analysis file can be constructed.
   
   • See the PIN Study's documentation (PIN 1 and 2, PIN 3, or Postpartum) to identify the source and the variable names. (See example below.)
   • Include specifications about any restrictions on the data set to limit it to a desired population, e.g., only women who have folate values or only women who completed the Life Events Questionnaire.
   • Review the list with the co-investigator.
   • Submit the requested list to Nancy Dole and the collaborating study investigator.
   • Be sure to include a date by which the analysis file is needed.  Because of limited programmer time, at least a month should be allowed to fulfill these requests.
     

Below is an example of a source file and variable list, from the PIN 1 and 2 data, to request creation of an analysis data set (pay particular attention to notations in the documentation that indicate multiple observations per respondent — they require special manipulation by the analyst to generate counts, the first observation, the last observation, etc. and will be given to the requestor as separate, unmerged, data sets):
