One of the challenges that often confront family scientists and clinicians is the issue of missing data (MD). It is not uncommon for values to be missing on a number of variables in an empirical study. Thus, marriage and family therapists who adopt a quantitative approach are often forced to respond to the incompleteness of the collected data in their efforts to ensure fidelity of the information provided by the participants. While there has been a steady growth in empirical studies of MD, marriage and family therapy (MFT) research has not emphasized current advancements, as evidenced in the field’s flagship journals.
