Cultural Adaptation and Validation of the Freiburg Life Quality Assessment-Wound Module to Brazilian Portuguese

Abstract

Objectives: to adapt the Freiburg Life Quality Assessment-Wound Module to Brazilian Portuguese and to measure its psychometric properties: reliability and validity. Method: the cultural adaptation was undertaken following the stages of translation, synthesis of the translations, back translation, committee of specialists, pre-test and focus group. A total of 200 patients participated in the study. These were recruited in Primary Care Centers, Family Health Strategy Centers, in a philanthropic hospital and in a teaching hospital. Reliability was assessed through internal consistency and stability. Validity was ascertained through the correlation of the instrument's values with those of the domains of the Ferrans and Powers Quality of Life Index-Wound Version and with the quality of life score of the visual analog scale. Results: the instrument presented adequate internal consistency (Cronbach alpha =0.86) and high stability in the test and retest (0.93). The validity presented correlations of moderate and significant magnitude (-0.24 to-0.48, p<0.0001). Conclusion: the results indicated that the adapted version presented reliable and valid psychometric measurements for the population with chronic wounds in the Brazilian culture. Descriptors: Wounds and Injuries; Quality of Life; Validity of Tests. 1 Paper extracted from master's thesis "Adaptação cultural e validação do 'Freiburg life quality assessment-wound' para a língua portuguesa do Brasil", presented

Validation of “Wound QoL” Hebrew version disease‐specific questionnaire for patients with lower extremity ulcerations

“…Subsets PF and EDL in the SF12v2 are constructed from 2 dichotomous and 1 5‐level question, which may explain the higher variability of this subset. The median values are similar in value and variations to other HRQoL instrument studies . Floor and ceiling effects had a satisfactory level, with floor level slightly exceeding the 15% limit by 0.3%.…”

“…The median values are similar in value and variations to other HRQoL instrument studies. 8,9,11,14,17 Floor and ceiling effects had a satisfactory level, with floor level slightly exceeding the 15% limit by 0.3%. The mean value variations of subsets between both questionnaires may imply Wound QoL sensitivity to patients' perception of physical, mental, and everyday life functioning, while high significance of correlations between subsets may indicate the relevance of the construct, representing health status by physically and mentally interrelated health evaluation groups.…”

“…These factors often require more holistic health assessment and care than wound treatment itself . A QoL tool enables the evaluation of patients’ health status and estimation of the need for additional treatment …”

“…9,10 A QoL tool enables the evaluation of patients' health status and estimation of the need for additional treatment. 8,10,11 An integrative review 12 of disease-specific QoL evaluation tools reveals that only a limited number of LEUspecific instruments is in use worldwide; most of them are related to venous rather than diabetic foot ulcerations. 12,13 The most popular health-related quality of life (HRQoL) assessment tools are SF36 with its shorter forms, a diseasespecific tool like McGill Short Form Pain Questionnaire, Charing Cross Venous Leg Ulcer Questionnaire, EuroQoL (EQ), Diabetic Foot Ulcer Scale-Short Form, and others.…”
