If the researcher plans to store contact information or other identifiable information collected during the telephone interviews for future purposes, the telephone script must describe this plan, including a description of:

• what information will be retained
• the purpose of retaining the information
• who will have access to the information
• the confidentiality and security protections for preventing unauthorized use of the information

Retention of sensitive information (e.g., data about illicit or stigmatizing behavior; social security numbers) is strongly discouraged.
