The purpose of this study was to evaluate the acceptability of a brief, video-based parental intervention that modeled parent-child communication about tobacco, delivered within an emergency department (ED) setting. While waiting to be seen by a physician in the ED, 20 parent-youth dyads watched the video together and then private, semi-structured focused interviews were conducted around the "take-home" message and views on the settings, actors, and content of the videos. Dyads agreed that the design, delivery, and content of the video intervention were acceptable, realistic, and useful in providing parental reinforcements about the importance of parent-youth tobacco communication, and the ED was considered to be a good setting for watching the video. Findings support the development and delivery of such an ED intervention and aids in determining content and scenarios for future intervention development. (Contains 2 figures.)
