          ABSTRACT

          CONTEXT AND OBJECTIVE:

          Uterine fibroids (UF), also known as leiomyomas, are the most prevalent gynecological tumors. The Uterine Fibroid Symptoms and Quality of Life (UFS-QOL) is the only specific questionnaire that assesses symptom intensity and quality-of-life issues for women with symptomatic UF; however, it only exists in the English language. Thus, we aimed to translate and culturally validate the ­UFS-QOL questionnaire for the Brazilian Portuguese language.

          DESIGN AND SETTING:

          Cross-sectional study, Department of Gynecology and Obstetrics, FMRP-USP.

          METHODS:

          113 patients with UF (case group) and 55 patients without UF (control group) were interviewed using the UFS-QOL questionnaire after translation and cultural adaptation. The Short Form-36 questionnaire was used as a control. Demographic and psychometric variables were analyzed.

          RESULTS:

          Women with UF presented higher mean age, body mass index, weight, parity and comorbidities than the control group (P < 0.05). The most prevalent complaints were abnormal uterine bleeding (93.8%), pelvic pain (36.3%) and extrinsic compression (10.6%) and these presented adequate construct validity regarding UFS-QOL severity (P < 0.05). The UFS-QOL questionnaire presented good internal consistency regarding symptom severity and quality-of-life-related domains (intraclass correlation coefficient, ICC = 0.82/0.88). Structural validity presented correlation coefficients ranging from 0.59 to 0.91. Test-retest comparison did not show differences among the UFS-QOL subscales. After treatment, women with UF presented improvements on all subscales.

          CONCLUSION:

          The UFS-QOL questionnaire presented adequate translation to the Brazilian Portuguese language, with good internal consistency, discriminant validity, construct validity, structural validity and responsiveness, along with adequate test-retest results.

          RESUMO

          CONTEXTO E OBJETIVO:

          O leiomioma uterino (LU) é o tumor ginecológico mais comum. Existe apenas um questionário específico que avalia a intensidade de sintomas e qualidade de vida de mulheres com LU sintomático, o Uterine Fibroid Symptom and Quality of Life (UFS-QOL), porém somente na língua inglesa. Dessa forma, objetivamos traduzir e validar culturalmente o questionário UFS-QOL para a língua portuguesa brasileira.

          TIPO DE ESTUDO E LOCAL:

          Estudo transversal, Departamento de Ginecologia e Obstetrícia da FMRP-USP.

          MÉTODOS:

          113 pacientes portadoras de LU (grupo caso) e 55 pacientes-controle foram entrevistadas com o questionário UFS-QOL após tradução e adaptação cultural. O questionário Short Form-36 foi utilizado para controle. Variáveis demográficas e psicométricas foram analisadas.

          RESULTADOS:

          As mulheres com LU apresentaram maior média de idade, índice de massa corporal, peso, paridade e comorbidades do que o grupo controle (P < 0,05). As queixas mais prevalentes foram sangramento uterino anormal (93,8%), dor pélvica (36,3%) e compressão extrínseca (10,6%) e estas apresentaram adequada validade de constructo com a gravidade indicada pelo UFS-QOL (P < 0,05). O questionário UFS-QOL apresentou boa consistência interna com a gravidade dos sintomas e com os domínios relacionados a qualidade de vida (coeficiente de correlação intraclasse, CCI = 0,82/0,88). A validade estrutural mostrou coeficientes de correlação variando de 0,59 até 0,91. A comparação teste-reteste não mostrou diferença entre as subscalas do UFS-QOL. Depois do tratamento, as mulheres com LU apresentaram melhora em todas as subscalas.

          CONCLUSÃO:

          O questionário UFS-QOL apresentou adequada tradução para a língua portuguesa brasileira, com boa consistência interna, validade de constructo/discriminatória, estrutural e responsividade, assim como adequados resultados teste-reteste.

            The MOS 36-item short-form health survey (SF-36). I. Conceptual framework and item selection.

            A 36-item short-form (SF-36) was constructed to survey health status in the Medical Outcomes Study. The SF-36 was designed for use in clinical practice and research, health policy evaluations, and general population surveys. The SF-36 includes one multi-item scale that assesses eight health concepts: 1) limitations in physical activities because of health problems; 2) limitations in social activities because of physical or emotional problems; 3) limitations in usual role activities because of physical health problems; 4) bodily pain; 5) general mental health (psychological distress and well-being); 6) limitations in usual role activities because of emotional problems; 7) vitality (energy and fatigue); and 8) general health perceptions. The survey was constructed for self-administration by persons 14 years of age and older, and for administration by a trained interviewer in person or by telephone. The history of the development of the SF-36, the origin of specific items, and the logic underlying their selection are summarized. The content and features of the SF-36 are compared with the 20-item Medical Outcomes Study short-form.
