Health-related quality of life after XXXX : reliability and validity of the Duke Health Profile for use in Vietnam.

@entity1 @entity717 @entity64
INTRODUCTION: Health-related quality of life (HRQoL) is commonly used to assess outcomes after @entity64 . The Duke Health Profile (DHP) has been translated and culturally adapted for use in Vietnam, but its reliability and validity for use with @entity64 @entity1 in Vietnam or elsewhere have not been assessed. METHODS: First-ever @entity64 @entity1 (n  =  108) who were admitted to 115 @entity1 's Hospital between February and September 2012 and survived for 3  months after @entity64 had HRQoL assessed using the DHP and a comparison instrument (EQ-5D). Caregivers of 94 @entity1 completed these questionnaires as a proxy. After 1  week, these questionnaires were re-administered to @entity1 and proxies. RESULTS: The mean differences between test and retest assessments of HRQoL by @entity1 were small and not clinically meaningful and were not consistently associated with sex, age, type of @entity64 or severity of @entity717 . Direct assessments by the @entity1 were on average greater than those obtained from the proxy. The ICCs ranged from 0.60 to 0.86 ( @entity1 test-retest) and from 0.55 to 0.98 ( @entity1 -proxy agreement). The ICCs were greatest for physical functioning components ( @entity1 test-retest 0.63-0.86, @entity1 -proxy 0.69-0.98). The correlations between the DHP dimensions and EQ-5D were generally stronger when they measured similar constructs (r  =  0.53-0.66) and were lower for less related constructs (r  =  0.11-0.43). CONCLUSION: The DHP has moderate reliability and validity for use with @entity64 @entity1 in Vietnam even when information is obtained from proxy respondents.
