Missing Data as a Variable/ Best Practices

You may wish to examine missing data an outcome itself, as there may be information in the missingness. The act of failing to respond vs. responding might be of interest. This can be examined through a "dummy variable," representing whether a person has missing data or not on a particular variable. You can then do some analyses to see if there any relationship that develop. 

Osborne (2013) provides some best practices in dealing with missing data that are great to remember.

• First, do no harm.be careful in your  methodology to minimize  missing data.
• Be transparent. Report any incidence of missing data (rates by variable, and reason for missing data if known). This can important information for readers.
• Explicitly discuss whether data are missing at random (i.e., if there are differences between individuals with complete and incomplete data). 
• Discuss how you as the researcher dealt with issue of incomplete data.
