All data will be stored in locked file cabinets behind locked doors in the PIs research laboratory until entered into the research database. Computer-based data entry will not require hard copy storage. All data collected via paper-pencil will be double entered into the research database by independent research assistants and results checked for quality control (QC). Once all hard copies have been entered, they will be scanned into PDF files for storage; all hard copies will be shredded. We will maintain the original signed consent forms for our records (these documents will not be shredded and will be kept in a locked file cabinet). Electronic scanned files will be stored in password protected files for security purposes. All discrepancies will be validated by chart review before the data are merged into the larger database. The database will contain item-level data to avoid the need for subsequent data entry processes as potential data analyses arise. Periodic QC checks will be conducted by our IT personnel and provided to the PI. All electronic records will be maintained on password protected computers behind locked doors in the PI's office space. All files will be backed up weekly on an independent external hard drive, which is also password protected.
