Summary: | The Interpersonal Exchange Model of Sexual Satisfaction Questionnaire (IEMSSQ) is one of the few instruments that has been developed from a theoretical model and assess sexual satisfaction. In addition, it has been successfully validated in Spanish heterosexual population. The objective of this study is to adapt and examine its psychometric properties (reliability, evidence of validity, and measurement invariance across sexual orientation and sex) in gay people in a relationship. Method: A sample of 1,820 adults, of whom 50% are gay people and 55% men, answered the Spanish version of the IEMSSQ. In addition, subjects with gay orientation answered the Massachusetts General Hospital-Sexual Functioning Questionnaire and the Dyadic Adjustment Scale. Results: When comparing by sex and sexual orientation, the IEMSSQ has a strict invariant structure. Its reliability is good, and the evidence of construct and concurrent validity is adequate. However, the components of equality are moderate. Conclusions: The IEMSSQ makes it possible to compare the sexual satisfaction between gay/heterosexual men and women, presenting good psychometric properties in gay people, constituting an useful instrument in the clinical and research field.
El Interpersonal Exchange Model of Sexual Satisfaction Questionnaire (IEMSSQ) es uno de los escasos instrumentos que evalúan la satisfacción sexual desde un modelo teórico y ha sido validado con éxito en población española heterosexual. El objetivo de este estudio es adaptar y examinar sus propiedades psicométricas (fiabilidad, evidencias de validez e invarianza según orientación sexual y sexo) en adultos gais con una relación de pareja. Método: Una muestra de 1.820 adultos, de los cuales el 50% son gais/lesbianas y el 55% hombres, contestó a la versión española del IEMSSQ. Además, los sujetos con orientación gay contestaron el Massachusetts General Hospital-Sexual Functioning Questionnaire y la Escala de Ajuste Diádico. Resultados: El IEMSSQ posee una estructura invariante estricta, por sexo y orientación sexual. Su fiabilidad es buena, y las evidencias de validez de constructo y concurrente adecuadas, aunque moderadas en los componentes de igualdad. Conclusiones: El IEMSSQ permite comparar la satisfacción sexual entre hombres gais y mujeres lesbianas y heterosexuales, presentando buenas propiedades psicométricas en adultos gais, constituyendo un instrumento útil en el ámbito clínico y en el de la investigación. |
