Validation of a Norwegian version of the Burn Specific Health Scale

Background: The abbreviated Burn Specific Health Scale (BSHS-A) is an 80-item questionnaire that has proven useful in measuring physical, mental, social and general health in burn Survivors. The aim of this Study wits to adapt the BSHS-A into Norwegian. including assessing reliability and validity. Methods: Standard procedures for forward and backward translation including discussions with professionals and patients to ensure conceptual equivalence were used. A pilot Study (11 burn patients) confirmed that the Norwegian version (BSHS-N) was clear, understandable and easy to self-administer. Subsequently, 95 adults admitted to the Burn Center, Haukeland University Hospital, between 1995 and 2000 entered a validation study by completing the BSHS-N and the general health Measure SF-36. Sixty-nine of the 95 (72%) responders completed a retest. Results: The overall internal consistency reliability (Cronbach's alpha = 0.97) and the test-retest reliability (ICC = 0.95) for the BSHS-N were satisfactory. Tests for criterion validity showed expected patterns for association between comparable domains in the BSHS-N and the SF-36, with correlations ranging from r = 0.61 to 0.81. Tests for construct validity showed that patients with full thickness injury (P = 0.003), patients hospitalised more than 10 days (P = 0.003), patients undergoing more than two operations (P = 0.001) and patients unemployed at the time of study (P < 0.001), had significantly lower total scores than the rest of the patients. Conclusion: BSHS-N seems to be a reliable and valid instrument for use in the Norwegian population. The translation and cross-cultural adaptation of this instrument allows for comparative international studies. (C) 2003 Elsevier Science Ltd and ISBI. All rights reserved.
