Cross cultural adaptation and validation of burn specific health scale- brief in Nepali (BSHS-B-Np)

Validation of the Spanish version of the Burn Specific Health Scale-Brief (BSHS-B) questionnaire

Background

The Burn Specific Health Scale-Brief (BSHS-B) is considered a validated questionnaire to evaluate quality of life after burn. The purpose of this study was to translate the BSHS-B into Spanish and perform its cross-cultural adaptation.

Methods

First, BSHS-B was translated from English into Spanish. Subsequently, 84 patients answered the Spanish version of BSHS-B and SF-36 scales to assess the reliability (Cronbach’s alpha), construct validity (Spearman rank test), and stability in time (intra-class correlation coefficient).

Results

The BSHS-B-Sp showed a good internal consistency with a global Cronbach’s alpha of 0.96. Correlations between the major domains of BSHS-B and SF-36 are reported with Spearman’s coefficient ranging from 0.29 to 0.87 in all sub-domains (p < 0.01). Stability in time was confirmed by intra-class correlation coefficient (0.91–0.99 for every sub-domain and 0.98 for global score, p < 0.001).

Conclusions

The Spanish version of the BSHS-B demonstrated an appropriated internal consistency, construct validity, and stability in time. This fact supports its applicability to evaluate the quality of life of burn patients.

Evaluation of the psychometric properties of the burn specific health scale-brief: A National Institute on Disability, Independent Living, and Rehabilitation Research Burn Model System Study

OBJECTIVE

The Burn Specific Health Scale-Brief (BSHS-B) is a commonly used burn specific health outcome measure that includes 40 items across nine subscales. The objective of this study was to use both classical and modern psychometric methods to evaluate psychometric properties of the BSHS-B.

METHODS

Data were collected post burn injury by a multisite federally funded project tracking long term outcomes. We examined dimensionality, local dependence, item fit, and functioning of response categories, homogeneity, and floor and ceiling effects. Items were fit to Item Response Theory models for evaluation.

RESULTS

A total of 653 adults with burn injury completed the BSHS-B. Factor analyses supported unidimensionality for all subscales, but not for a total score based on all 40 items. All nine of the subscales had significant ceiling effects. Six item pairs displayed local dependence suggesting redundance and 11 items did not fit the Item Response Theory models. At least 15 items have too many response options.

CONCLUSIONS

Results identified numerous psychometric issues with the BSHS-B. A single summary score should never be used for any purpose. Psychometric properties of the scale need to be improved by removing redundant items, reducing response categories and modifying or deleting problematic items. Additional conceptual work is needed to, at a minimum, revise the work subscale and optimally to revisit and clearly define the constructs measured by all the subscales. Additional items are needed to address ceiling effects.

The CARe Burn Scale-Adult Form: Translation and linguistic validation into Finnish

BACKGROUND

Burn injury can dramatically deteriorate health-related quality of life. Effective burn care may minimize the impact of the burn injury and ensure optimal functional outcome. This requires continuous improvement in burn care and assessment of treatment results. The aim of this study was to translate, culturally adapt and linguistically validate the CARe Burn Scale-Adult Form, a burn-specific patient-reported outcome measure, into Finnish.

METHODS

The translation process followed the International Society for Pharmacoeconomics and Outcomes Research guidelines consisting of forward and backward translations, pilot-testing and cognitive debriefing interviews of five burn patients, and proofreading before finalizing. The process involved expert panel meetings and continuous discussion between the developers of the Scale and the research group.

RESULTS

In the forward translation 10 amendments were required. After the backward translation, 12 items were reworded. Cognitive debriefing interviews led to three alterations enhancing the comprehensiveness and accuracy of the translation. The translation was reviewed by burn occupational therapists for practicality, resulting in 12 modifications. Minor grammatical changes were made after proofreading.

CONCLUSION

The Finnish version is the first foreign translation of the CARe Burn Scale. It is equivalent to the original Scale and ready for psychometric validation with burn patients in Finland.
