The purpose of this study was to better understand if a health educational presentation using culturally adapted materials was understandable and culturally appropriate, and that the content was retained, in an older Vietnamese American population. This study used cognitive interviewing. A convenient sampling was used to recruit eight participants by staff of a community-based organization from its client base. This is the first study to document that family eating style poses a challenge for estimating food intake among Vietnamese Americans. Participants who ate in a family eating style were not able to recall or estimate the number of servings of protein and vegetables. Some older Vietnamese Americans used food for healing and self-adjusted portion sizes from dietary recommendations. Cognitive interviewing is a useful method to improve comprehension, retention, and cultural appropriateness of health educational materials. Further nutrition research concerning intake measurement in ethnic groups that practice a family eating style is warranted.
