Symbols used in such studies need to be evaluated for their cross-cultural appropriateness because a given symbol may have different meanings or acceptability in different cultures, which may affect results of such studies. Objectives: To evaluate if using symbols to differentiate health states of different severity is useful and culturally acceptable in a multi-ethnic, urban Asian population. Methods: Using in-depth interviews with adult Chinese, Malay, and Indian Singaporeans conducted in English/mother-tongue, subjects were shown a health state with 6 levels (Health Utilities Index 3 vision), each displayed with a symbol, and asked (1a) if symbols were useful in differentiating severity of each level (measured using dichotomous and 0-10 visual analog scale [VAS] scales) or (1b) offensive and (2) to assess 7 alternative sets of symbols. Results: Of 63 subjects (91% response rate), 18 (29%) felt symbols were useful in differentiating severity of each level. Reported usefulness of symbols was fair (median VAS score: 3.0, score exceeding 5.0 for 33% of subjects). One Malay subject felt symbols were offensive. Conclusions: Use of symbols for health state valuation was culturally acceptable and useful for some subjects. © 2008 Wee et al, publisher and licensee Dove Medical Press Ltd.||Source Title:||Patient Preference and Adherence||URI:||http://scholarbank.nus.edu.sg/handle/10635/108264||ISSN:||1177889X||DOI:||10.2147/PPA.S4142|
