Methodology | Exisiting Methodology | Lesson Learned from the 8 EAs | Revision to protocol |
Recruitment Strategy | A responsivity rate of 65% was assumed in response to the invitation letters. | The response rate used in the original protocol was not verified during the EA process. The average response rate across the 8 EA sites was 10% for the recruitment letters and not a rate of 65% cited in the protocol. | A response rate of 10% for the recruitment letters will be used for additional EAs. A maximum of 3000 recruitment letters will be sent in each community. |
Recruitment was based on recruitment letters and phone calls | Given the low response rate resulting from the letter recruitment, door-to-door recruitment may be an option to provide a higher rate of response. | Include door-to-door recruitment as an option for recruitment, as needed. | |
Administation of Questionnaire | Questionnaires were only administered in person | Based on modifications made in response to COVID-19 protocols, the addition of administering questionnaires by phone should be made. | Administration of questionnaires via phone will be added as an option to the protoocl. |
Questionnaire | Questions regarding water intake and the use of treatment systems before PFAS was mitigated in the water were not included. | During the data analysis, questions regarding water use and treatment systems in place before the PFAS in water was mitigated would have been helpful. | Additional questions regarding water intake and treatment systems used prior to mitigation will be included in the questionnaire. |
Data Management Plan (DMP) (Appendix I) | DMP included in protocol | Additional requirements were included in the DMP appendix | Additional requirements were included in the DMP appendix: 1. NCEH/ATSDR Data Use Agreement Template (Appendix I2). 2. Standard Operating Procedures (SOPs) for Data Management (Appendix I3) |
