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. 2025-12-16T08:20:00Z 2025-12-16T08:20:00Z 2025 journal article Sierra, J.
