The purpose of this study was to develop a health descriptive system as the first step of developing a generic preference-based health measure for children. The sample was recruited from two elementary schools and one university hospital. The total number of participants was 91 whose grades ranged from 1 to 6. Two trained interviewers asked various open-ended questions to elicit health concepts of children. All the interviews were recorded and transcribed. NVivo 10 was used for the qualitative analysis. Based on this qualitative analysis, the first draft of descriptive system was developed. Content validity was tested by children, teachers, and experts. Lastly, cognitive interview was performed on children. Over 100 words and phrases that were directly or indirectly related to concept of health were extracted. After carefully and repeatedly reviewing these words and phrases, we categorized them into 8 themes from which a descriptive system was developed. We modified the items and the levels of the items based on the interviews to test its content validity and the cognitive interview results. The final descriptive system named as CH-6D included six items-study, running/playing sports, energy, mood, pain/discomfort, and playing or getting along with friends, of which levels were either 3 or 4. This study developed a health descriptive system for children which consisted of 6 items. Valuation studies where values are estimated for the health states of CH-6D are needed to utilize this measure for an economic evaluation for children.
