Selecting and administering dietary assessment tools. The evaluation instrument selected depends on the purpose for
reporting the measured outcomes, the degree of accuracy and type of data needed to fulfill that purpose, the skill of the
staff, and the size, ability, and cooperation of the study population. For the low-income audiences, measurement tools should be easy to comprehend, quick to administer, sensitive to change, and appropriate to audience diversity. It is important to recognize the limitations of traditional methods used to measure dietary change in low-income audiences and to make adjustments when possible. Respondents may have limited reading, writing, and comprehension skills.They may be reluctant to report what and how much they eat, especially if they consider some foods to be of low status or if they have concerns that professionals might be judging their ability to care adequately for their children through the foods they
provide. Fear that the children may be removed from the home might cause them to withhold or fictionalize responses.
