Resumo

As disfunções sexuais constituem um problema de saúde de elevada prevalência, tornam‐se necessários instrumentos de avaliação adaptados para a população portuguesa.

O objetivo deste estudo foi validar o Massachusetts General HospitalSexual Functioning Questionnaire (MGH‐SFQ) para a população portuguesa.

A idade dos participantes variou de 18 a 89 anos (M = 29,66; SD = 13,05), 32,6% (n = 352) foram homens e 67,4% (n = 727) mulheres.

Resultados

O alfa de Cronbach obtido foi de 0,91 e as propriedades psicométricas da escala foram adequadas. A validação do constructo foi avaliada através da Análise Fatorial Confirmatória, configurou um modelo unidimensional adequado (RMSEA = 0,041, CFI = 0,974).

Abstract
Introduction

Sexual dysfunctions are a high prevalence health problem, making it necessary to provide assessment instruments adapted to the Portuguese population.

Methods

The purpose of this study was to validate the Massachusetts General Hospital‐Sexual Functioning Questionnaire (MGH‐SFQ) for the Portuguese population. Participants in this study were 1079 Portuguese adults who completed a sociodemographic questionnaire and the MGH‐SFQ. The participants’ ages varied between 18 and 89 years of age (M = 29.66; SD = 13.05), and 32.6% (n = 352) were men and 67.4% (n = 727) were women.

Results

The Cronbach's alpha obtained was .91 and the psychometric properties of the scale were adequate. The validation of the construct was evaluated through Confirmatory Factor Analysis, setting up a suitable one‐dimensional model (RMSEA = .041, CFI = .974).

Discussion

Taking into account the results of the psychometric validation, the sample size and the applicability of this instrument in clinical and sexological practice, we can confirm that this is a valid and reliable instrument to evaluate the sexual functioning of both Portuguese men and women.
