Best Practices

Always keep a copy of your Data Dictionary (Downloaded to Excel).
Do not change variable names or values of categorical field types once you begin collecting real data.
Group variables together that follow the data entry work flow.
Keep forms fairly short to minimize risk of data loss.
Use categorical field types (yes/no, multiple choice, etc.) whenever possible.
When using text fields, add field validation to minimize data entry errors.
Involve a statistician early during the development of the database.
Using the multi-page surveys feature will allow the participant to complete the survey in sections with each completed page uploading to REDCap.
Enable the Save and Return later feature for large surveys.
