Abstract

Objective To validate the six-item female sexual function index (FSFI-6) in middle-aged Brazilian women.

Methods Cross-sectional observational study, involving 737 (premenopausal n = 117, perimenopausal n = 249, postmenopausal n = 371) Brazilian sexually active women, aged between 40 and 55 years, not using hormonal contraceptive methods. The Brazilian FSFI-6 was developed from the translation and cultural adaptation of the Portuguese FSFI-6 version. The participants completed a general questionnaire, the FSFI-6, and the menopause rating scale (MRS). The validation was performed by AMOS 16.0 software (SPSS, Inc., Chicago, IL, USA) for a confirmatory factor analysis (CFA). The chi-square of degrees of freedom (χ2/df), the comparative fit index (CFI), the Tucker-Lewis index (TLI) and the root-mean-square error of approximation (RMSEA) were used as indices of goodness of fit. Cronbach α coefficient was used for internal consistency.

Results The process of cultural adaptation has not altered the Brazilian FSFI-6, as compared with the original content. The CFA for the FSFI-6 score showed an acceptable fit (χ2/df = 3.434, CFI = 0.990, TLI = 0.980, RMSEA = 0.058, 90% confidence interval (90%CI) = 0.033–0.083, p ≤ 0.001) and a good reliability was established in FSFI-6 and MRS (Cronbach α = 0.840 and = 0.854, respectively). In addition, 53.5% of the sample had low sexual function.

Conclusion The FSFI-6 was translated and adapted to the Brazilian culture and is a consistent and reliable tool for female sexual dysfunction screening in Brazilian middle-aged women.

Resumo

Objetivo Validar o Índice de Função Sexual Feminina - 6 itens (FSFI-6, na sigla em inglês) para mulheres brasileiras de meia-idade.

Métodos Estudo transversal observacional que incluiu 737 (pré-menopausa n = 117, perimenopausa n = 249, pós-menopausa n = 371) mulheres brasileiras sexualmente ativas, entre 40 e 55 anos, sem métodos contraceptivos hormonais. A versão brasileira do FSFI-6 foi desenvolvida através da tradução e adaptação cultural da versão portuguesa do questionário. As participantes preencheram um questionário com dados gerais, o FSFI-6 e a escala de avaliação da menopausa (menopause rating scale [MRS]). A validação do instrumento se deu através de análise fatorial confirmatória (CFA, na sigla em inglês), realizada pelo software AMOS 16.0 (SPSS, Inc., Chicago, IL, EUA). Qui-quadrado sobre graus de liberdade (χ2/df), índice de ajuste comparativo (CFI, na sigla em inglês), índice de Tucker-Lewis (TLI) e raiz média dos quadrados dos erros de aproximação (RMSEA, na sigla em inglês) foram utilizados como índices de adequação de ajustes. O coeficiente alfa de Cronbach foi utilizado para avaliar a consistência interna.

Resultados O processo de adaptação cultural não alterou a versão brasileira do FSFI-6, comparado ao conteúdo original. O CFA para o escore do FSFI-6 demonstrou ajuste aceitável (χ2/df = 3,434; CFI = 0,990; TLI = 0,980; RMSEA = 0,058; 90% IC = 0,033 a 0,083; p ≤ 0,001). Demonstrou-se boa confiabilidade entre FSFI-6 e MRS (alfa de Cronbach = 0,840 e = 0,854, respectivamente). Do total, 53,5% da amostra apresentou baixa função sexual.

Conclusão O FSFI-6 foi traduzido e adaptado culturalmente, e é uma ferramenta consistente e confiável no rastreamento de disfunções sexuais em mulheres brasileiras de meia-idade.
