Answer to Question 1

Preparation
 Ensuring that dates of birth and middle names were collected (to make later tracing easier)
 Identifying a contact person who lived at a different address
 Maintaining contact throughout the project with such mailings as birthday cards or regular newsletters

Persistence
 Beginning a trace of the person as soon as contact is lost
 Making multiple phone calls to set up appointments for interviews
 Showing willingness to conduct interviews at times and locations convenient for the respondent
 Providing incentives to offset the inconvenience of participation

Answer to Question 2

If we can't measure our hypothetical constructs, we can't really get a good sense of how they affect behavior. We won't have a good definition of our construct, so applying it will be difficult.
