Background: The Sexual Inhibition/Sexual Excitation Scales-Short Form (SIS/SES-SF) is a brief instrument for assessing the propensity for sexual excitement and inhibition in men and women. The aim of the present study was to provide evidence for the validity and reliability of the Spanish version of the SIS/SES-SF scores by examining invariance, reliability (information function and internal consistency), the relationship between the scores and sexual functioning, and presenting its standard scores. Method: A total of 2,223 Spanish heterosexuals (43.41% men and 56.59% women) aged 18 to 83 years (M = 39.94, SD = 11.95), distributed across age groups (18-34, 35-49, ≥ 50 years old) participated. Results: The three-factor structure of the Spanish version of SIS/SES-SF showed weak measurement invariance by sex and strict measurement invariance by age. The scores explained the dimensions of sexual functioning, especially sexual arousal and erection/lubrication. In addition, men and women without difficulties in sexual functioning demonstrated more propensity for sexual excitation and less sexual  inhibition. The standard scores are presented by sex and age group. Conclusions: The study provides evidence of the validity and reliability of the SIS/SES-SF measures, confirming its usefulness for assessing propensity to sexual excitation and inhibition.

Antecedentes: Las Sexual Inhibition/Sexual Excitation Scales-Short Form (SIS/SES-SF) son un instrumento breve que evalúa, en hombres y mujeres, la propensión hacia la excitación e inhibición sexual. El objetivo fue aportar evidencias de validez y fiabilidad a las puntuaciones de la versión española de SIS/SES-SF, examinando la invarianza, la fiabilidad (función de información y consistencia interna), la  relación de sus puntuaciones con el funcionamiento sexual, y presentar sus puntuaciones estandarizadas. Método: Participaron 2.223 españoles heterosexuales (43,41% hombres y 56,59% mujeres) de 18 a 83 años (M = 39,94; DT = 11,95), distribuidos en tres grupos de edad (18-34, 35-49, ≥ 50 años). Resultados: La estructura trifactorial de la versión española de SIS/SES-SF mostró nivel de invarianza débil por sexo y estricto por edad. Sus puntuaciones explicaron las dimensiones del funcionamiento sexual, especialmente excitación sexual y erección/lubricación. Además, hombres y mujeres sin dificultades en el funcionamiento sexual mostraron más propensión a la excitación sexual y menor inhibición sexual. Se presentan baremos de sus puntuaciones por sexo y grupos de edad. Conclusiones: Se aportan adecuadas evidencias de validez y fiabilidad a las medidas de SIS/SES-SF, lo que confirma la utilidad de este instrumento para evaluar la propensión a la excitación e inhibición sexual.
