Background: The Orgasm Rating Scale (ORS) is one of the few self-reported measures that evaluates the multidimensional subjective experience of orgasm.\n Aim: The objective of this study was to examine the psychometric properties of the ORS in context of sex-with-partner in a Spanish sample.\n Methods: We examined a sample of 842 adults from the general Spanish population (310 men, 532 women; mean age = 27.12 years, SD = 9.8). The sample was randomly divided into two, with a balanced proportion of men and women between each sub-sample. Sub-sample 1 consisted of 100 men and 200 women (33.3% and 66.6%) with a mean age of 27.77 years (SD = 10.05). Sub-sample 2 consisted of 210 men and 332 women (38.7% and 61.3%) with a mean age of 26.77 years (SD = 9.65). The ORS, together with the Sexual Opinion Survey-6 and the Massachusetts General Hospital-Sexual Functioning Questionnaire, was administered online. The survey included a consent form, in which confidentiality and anonymity were guaranteed.\n Outcomes: Based on exploratory factor analysis, we obtained a reduced 25-item version of the ORS, distributed along 4 dimensions (affective, sensory, intimacy, and rewards).\n Results: We performed both exploratory factor analysis and confirmatory factor analysis. The Spanish version of the ORS had adequate values of reliability that ranged from .78-.93. The 4 factors explained 59.78% of the variance. The factor structure was invariant across gender at a configural level. Scores from the ORS positively correlated with erotophilia and sexual satisfaction. The scale was useful to differentiate between individuals with orgasmic difficulties and individuals with no difficulties. We found that individuals with orgasmic difficulties showed a lower intensity in the affective, intimacy, and sensorial manifestations of orgasm.\n Clinical Translation: This version of the ORS could provide an optimum measure for the clinical assessment to identify individuals with difficulties in their orgasmic capacity, thus, it could be used as screening device for orgasmic dysfunction.\n Conclusions: The ORS is an appropriate measure for its use for both research and clinical purposes. As limitations, quota sampling implies that the extent to which the results can be generalized is modest. Measurement invariance did not reach the level of weak invariance, and it was not tested across sexual orientation because most individuals identified themselves as heterosexual. The ORS is a multidimensional measure of the subjective experience of orgasm which has adequate psychometric properties; it is a reliable and valid scale.
