Taxi Drivers at Risk: Tailoring Nutrition and Exercise Materials.

Cognitive interviewing was used to refine nutrition and exercise health education materials for use in the New York City taxi driver community. Cognitive interviews were conducted with taxi drivers at garages and community centers across New York City. Interviews were conducted in five rounds with approximately 10 interviews conducted in each round. Modifications were made to the education materials between rounds based on driver feedback. Interviews were transcribed, coded to identify areas needing improvement, and then used to modify materials. Areas that needed adaptation included colloquialisms, literacy level, complex jargon/terminology, vague/confusing phrasing, driver-specific and ethnic-specific preferences, visual aids, and mathematical calculations. These were organized into four key themes: linguistic responsiveness, occupational and cultural adaptation, visuals, and calculations. Cognitive interviewing is a useful method for refining health education materials in the diverse driver population. Cognitive interviewing revealed a need to reduce literacy level, avoid complex terminology, make further occupational and cultural adaptations, use clear visual aids, and avoid the use of complex calculations. Cognitive interviewing is an effective method for refining health education materials for immigrant and low literacy populations.
