Validity and Reliability Evidence and Norms for the Spanish Version of the Sexual Inhibition/Sexual Excitation Scales-Short Form.

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.

Relationship between Solitary Masturbation and Sexual Satisfaction: A Systematic Review.

Masturbation is a healthy sexual behavior associated with different sexual functioning dimensions, which highlights sexual satisfaction as an important manifestation of sexual wellbeing. This review aims to systematically examine studies that have associated masturbation with sexual satisfaction, both in individuals with and without a partner. Following the PRISMA statement, searches were made in the APA PsycInfo, Medline, Scopus, and Web of Science databases. The search yielded 851 records, and twenty-two articles that examined the relation between solitary masturbation and sexual satisfaction were selected. In men, a negative relation between masturbation and sexual satisfaction was observed in 71.4% of the studies, 21.4% found no such relation, and 7.2% observed a positive association. In women, 40% reported no relation, 33.3% a negative relation, and 26.7% a positive one. The negative association between solitary masturbation and sexual satisfaction is consistent with the previously proposed compensatory role of masturbation, especially for men. In women, compared to men, the complementary role of masturbation in relation to sexual relationships is observed to a greater extent and is associated more closely with sexual health. The importance of including different parameters beyond the masturbation frequency in future studies to explore its relation with sexual satisfaction is emphasized. This systematic review is registered in PROSPERO (CRD42023416688).

Validation of the Spanish Version of the Massachusetts General Hospital-Sexual Functioning Questionnaire (MGH-SFQ) with Sexual Arousal Measures in Men.

Objective: Provide new validity evidence of the Spanish version of the Massachusetts General Hospital-Sexual Functioning Questionnaire (MGH-SFQ) by associating its scores with measures of sexual arousal. Method: In a sample of 48 men, using a quasi-experimental design, sexual functioning, propensity for sexual inhibition/excitation, subjective sexual arousal, and genital response (penile plethysmography recorded with Biopac MP150 equipment) were evaluated. Results: Arousal and erection scores correlated with sexual inhibition due to the threat of performance failure (r = .29; p < .05) and genital response (r = .31; p < .05), respectively. Participants with difficulties in sexual functioning indicated greater sexual inhibition due to the threat of performance failure (p = .04) and lower intensity in their genital response (p = .05). Conclusions: The validity of the measures obtained with the Spanish version of the MGH-SFQ is supported, showing the erection item to be useful for the detection of possible erectile disorders.

Objetivo: Aportar nuevas evidencias de validez a la versión española del Massachusetts General Hospital-Sexual Functioning Questionnaire (MGH-SFQ), asociando sus puntuaciones a medidas de la excitación sexual. Método: En una muestra de 48 hombres, mediante un diseño cuasiexperimental, se evaluó el funcionamiento sexual, la propensión para la excitación/inhibición sexual, la excitación sexual subjetiva y la respuesta genital (pletismografía peniana registrada con un equipo Biopac MP150). Resultados: Las puntuaciones en excitación y erección del MGH-SFQ correlacionaron significativamente con la inhibición sexual por miedo al fallo en el rendimiento sexual (r = .29; p < .05) y con la respuesta genital (r = .31; p < .05), respectivamente. Los participantes con dificultades en el funcionamiento sexual, en comparación con los que mostraron un adecuado funcionamiento, indicaron mayor inhibición sexual por miedo al fallo en el rendimiento sexual (p = .04) y menor intensidad en su respuesta genital (p = .05). Conclusiones: Se avala la validez de las medidas obtenidas con la versión española del MGH-SFQ, mostrándose el ítem de erección útil para la detección de posibles trastornos eréctiles.

Translation, adaptation, and clinical validation of the Premature Ejaculation Diagnostic Tool in Spanish (Colombia).

Background: Premature ejaculation is the most prevalent form of sexual dysfunction in men. The Premature Ejaculation Diagnostic Tool (PEDT) is an instrument used to evaluate premature ejaculation. It offers adequate psychometric properties and good reliability. Aim: To adapt and validate a Colombian version of the PEDT in Colombian clinical and nonclinical samples. Methods: Two samples were used in this study. The first was made up of 1110 men who were recruited to evaluate validity and reliability. Their ages ranged from 19 to 65 years (mean ± SD, 39.71 ± 12.53). The second sample included 123 men (66.7%) who did not meet diagnostic criteria for premature ejaculation per the International Statistical Classification of Diseases and Related Health Problems (ICD-10), while 33.3% met ICD-10 criteria for this dysfunction. Their ages ranged from 18 to 65 years (34.19 ± 12.65). Scores were used to calculate the cutoff. Outcomes: A translated and adapted version of the PEDT was developed specifically for Colombia. All participants completed the Colombian version of the PEDT, a sociodemographic questionnaire, the Colombian version of the Massachusetts General Hospital-Sexual Functioning Questionnaire, and a semistructured interview based on the ICD-10. Results: The results showed adequate psychometric properties and satisfactory internal consistency and confirmed the 1-dimensional factorization of the scale. According to ICD-10 criteria, the study also confirmed significant differences between participants who self-reported premature ejaculation and those who did not. In addition, it showed adequate evidence of convergent validity, with a moderate correlation with sexual functioning scores. As a result, the cutoff point was set to 10.5, with an area under the curve of 96.8%. Therefore, a score ≥11 points suggested the presence of premature ejaculation. Clinical Translation: The current Colombian version of the PEDT is a useful instrument that determines the presence of premature ejaculation that is compatible with ICD-10 criteria. Strengths and Limitations: The Colombian version of the PEDT presents evidence of reliability and validity, a confirmed 1-dimensional factorization, and a cutoff point for Hispanic populations. More in-depth evaluation of the diagnosis of premature ejaculation is required, and further research among other Spanish-speaking countries and sexual minorities is recommended. Conclusion: The Colombian version of the PEDT is a psychometric adequacy tool for evaluating and diagnosing premature ejaculation, following the ICD-10 criteria.

Solitary Sexual Desire: Its Relation to Subjective Orgasm Experience and Sexual Arousal in the Masturbation Context within a Spanish Population.

The tridimensional sexual desire proposal (i.e., dyadic to partner, dyadic to attractive other and solitary) has been empirically supported. However, solitary sexual desire and its relationship to other dimensions of sexual functioning has received less attention. Hence, we examined the capacity of solitary sexual desire to explain the subjective orgasm experience (Study 1) and sexual arousal (Study 2) in the context of solitary masturbation. Study 1, composed of 2406 heterosexual adults (M age = 39.72, SD = 11.81), assessed for solitary sexual desire, dyadic sexual desire, and the intensity of the subjective orgasm experience obtained through solitary masturbation, along with other associated parameters. Study 2, consisting of 41 heterosexual young people (M age = 22.49, SD = 3.17), evaluated the genital response (penile circumference/vaginal pulse amplitude) and subjective arousal to sexually explicit films related to solitary masturbation. In both men and women, solitary sexual desire accounted for a significant percentage of the subjective orgasm experience obtained through solitary masturbation. In addition, in women, the propensity for sexual arousal was explained by solitary sexual desire. It is concluded that solitary sexual desire -as opposed to dyadic- is important to explain sexual arousal and orgasm in the solitary masturbation context. These results highlight the importance of addressing sexual desire in the solitary context, given its implications with other dimensions of sexual functioning.

Masturbation in middle and late adulthood: its relationship to orgasm.

The relation of masturbation to orgasmic facility and orgasm satisfaction in the sexual relationships context was examined in elderly population. This cross-sectional study included 546 Spanish heterosexual adults aged 50-83 years. They completed a Socio-Demographic Questionnaire, and scales to assess negative attitude towards masturbation, solitary sexual desire, subjective orgasm experience in the solitary masturbation context and orgasmic facility and orgasm satisfaction in sexual relationships. Significant differences were observed on all the masturbation-related indicators between men and women. For men, a regression model was obtained in which age (ß = 0.15), current masturbation frequency (ß = 0.18) and negative attitude towards masturbation (ß = 0.17) explained 8% of the difficulty in orgasmic facility, and another in which age (ß = 0.14) and negative attitude towards masturbation (ß = 0.13) explained 8% of orgasm satisfaction. For women, two regression models were obtained, in which the Affective dimension of the subjective orgasm experience in masturbation explained 11% of orgasmic facility (ß = -0.22) and 15% of orgasm satisfaction (ß = -0.33) in sexual relationships. Significant differences in the intensity of the subjective orgasmic masturbation experience were observed between elderly people with and without difficulties in orgasmic facility and orgasm satisfaction in sexual relationships.

Sexual double standard: A gender-based prejudice referring to sexual freedom and sexual shyness.

The sexual double standard (SDS) consists of judging men and women differently for the same sexual behavior. This study contributes to research on the factors that determine inconsistent adherence to the SDS. It uses a descriptive methodology to analyze the association between individual and contextual factors both with adherence to the SDS, and with four SDS adherence typologies (man-favorable SDS, woman-favorable SDS, egalitarian and ambivalent). A total of 1,206 heterosexual Spanish adults (603 men and 603 women) participated. The mean age in the male sample was 41.7 (SD = 14.25), in the female sample M = 40.84 (SD = 14.24). The results show that the conceptualization of SDS as a gender-based prejudice is valid to understand the bias of ingroup favoritism that SDS implies: adherence to SDS is more related to the identity of the gender role of men (vs. women). In addition, evidence is provided that the normative context and domain of sexual behavior (i.e., sexual freedom or sexual shyness) determine the form that SDS adopts to express itself. The domain of behaviors related to sexual shyness (vs. domain related to sexual freedom) better discriminates between the different four SDS adherence typologies. The importance of adopting different levels of analysis (i.e., individual, intergroup, societal) to explain and predict both SDS adherence and the prevalence of SDS adherence typologies is discussed.

Sexual Activity in Peruvian Adolescents: Relevance of Socio-Demographic Variables and Sexual Attitudes.

The aim of this study was to explain the masturbation frequency and sexual relationships in adolescents based on age, religious adherence, erotophilia, attitudes toward sexual fantasies and masturbation, and the traditional sexual double standard. A sample of 1120 Peruvian adolescents aged 13-17 years responded to a socio-demographic questionnaire and different scales about sexuality. The frequency of masturbation and sexual relationships, as well as in the sexual attitudes evaluated differed by sex, with boys scoring higher. The masturbation frequency was explained by erotophilia in boys, and by positive attitudes toward sexual fantasies in both sexes. The frequency of sexual relationships was explained by age and positive attitudes toward sexual fantasies in boys and only by the latter in girls. Positive attitudes toward sexual fantasies stand out as a variable for understanding sexual activity in adolescents.

Study of Sexual Concordance in Men and Women with Different Typologies of Adherence to the Sexual Double Standard.

Background/Objective: Sexual concordance (i.e., relationship between genital response and subjective sexual arousal) is higher in men than in women. Among the factors that could explain this difference would be the sexual double standard (SDS). Sexual concordance is examined by SDS typologies of adherence (egalitarian, man-favorable, and woman-favorable). Method: During exposure to a film with sexual content, genital response (penile circumference/vaginal pulse amplitude) and self-reported sexual arousal were recorded in 104 young adults (42 men and 62 women), distributed into SDS typologies of adherence on the basis of their scores on the Sexual Double Standard Scale. Results: Sexual concordance was obtained in men and women with egalitarian and man-favorable typology. Subjective sexual arousal explained a significant percentage of the variance in genital response in the egalitarian typology (men: R2  = .32, p < .01; women: R2  = .19, p < .05) and man-favorable typology (men: R2  = .21, p < .05; women: R2  = .23, p < .05). Conclusions: Agreement between genital responsiveness and subjective sexual arousal depends on DES adherence typology.

Antecedentes/Objetivo: La concordancia sexual (i.e., relación entre respuesta genital y excitación sexual subjetiva) parece ser mayor en hombres que en mujeres. Entre los factores que podrían explicar dicha diferencia estaría el doble estándar sexual (DES). Se examina la concordancia sexual en función de la tipología de adhesión al DES (igualitaria, favorable al hombre y favorable a la mujer). Método: Durante la exposición a un filme de contenido sexual, se registró la respuesta genital (circunferencia peniana/amplitud del pulso vaginal) y la excitación sexual autoinformada de 104 adultos jóvenes (42 hombres y 62 mujeres), distribuidos en las tipologías de adhesión al DES a partir de sus puntuaciones en la Sexual Double Standard Scale. Resultados: Se obtuvo concordancia sexual en hombres y mujeres con tipología igualitaria y favorable al hombre. La excitación sexual subjetiva explicó un porcentaje significativo de la varianza de la respuesta genital en la tipología igualitaria (hombres: R2  = 0,32, p < 0,01; mujeres: R2  = 0,19, p < 0,05) y en la favorable al hombre (hombres: R2  = 0,21, p < 0,05; mujeres: R2  = 0,23, p < 0,05). Conclusiones: El acuerdo entre la respuesta genital y la excitación sexual subjetiva depende de la tipología de adhesión al DES.

Colombian Clinical Validation of the International Index of Erectile Function (IIEF-5).

BACKGROUND: Erectile dysfunction represents an important health problem and the instrument most frequently used for the evaluation of its evaluation is the International Index of Erectile Function (IIEF-5). AIM: Due to lack of adaptation and validation for Spanish-speaking populations, this study aimed to adapt and validate the Colombian version of International Index of Erectile Function (IIEF-5). METHODS: Two independent samples were evaluated. One used to validate the scale and the other to calculate cut-off point of this version, with 2,021 men from the general population and outpatients from a clinic. The age range was 18 to 75 years old (M = 37.80; SD = 14.06). The second sample included 74 men, 64.9% did not meet DSM-5 criteria for erectile dysfunction, and 35.1% meet DSM-5 criteria to ED. Age range was 19 to 73 years old (M = 40.38; SD = 13.22). OUTCOMES: All participants answered the Spanish versions of the International Index of Erectile Function-5 (IIEF-5) and the Massachusetts General Health-Sexual Functioning Questionnaire. RESULTS: The Colombian version of IIEF-5 showed adequate psychometric properties, confirmed the one-dimension factorization of the scale, and showed adequate evidence of reliability and validity. Significant differences were observed in the IIEF-5 total score between the non-clinical and clinical groups who meet DSM-5 criteria for erectile dysfunction, with a large effect size. Also, the cut-off the Colombian version was set to 16, with an area under the curve of 94.9%. CLINICAL IMPLICATIONS: The Colombian version of the IIEF-5 is a useful evaluation instrument that provides to determine the presence of erectile dysfunction compatible with DSM-5 criteria. STRENGTHS & LIMITATIONS: The inventory reports adequate psychometric properties, a confirmed one-dimensional structure, evidence of reliability and validity, and the first cut-off point for Hispanic populations. A more in-depth evaluation of the diagnosis of ED and thus replication in other Spanish-speaking countries and sexual minorities is recommended. CONCLUSION: The Spanish version of the IIEF-5 is a useful evaluation tool for identifying erectile dysfunction, following DSM-5 criteria.

Association of Sexual Attitudes with Sexual Function: General vs. Specific Attitudes.

Background: Sexual attitudes are related to the expression of sexuality and have been associated with indicators for sexual health. The main aim of this study was to determine the explanatory capacity of general (i.e., erotophilia) and specific (i.e., toward sexual fantasies and masturbation) sexual attitudes on different sexual functioning dimensions (sexual desire, sexual arousal, lubrication/erection, ability to have an orgasm and orgasm satisfaction). Methods: The sample consisted of 2000 heterosexual adults (1044 women, 956 men) aged 18-83 years. Results: The explanatory models for women mainly showed that positive attitudes toward sexual fantasies (ß range = -0.35, -0.249) and age (ß range = -0.111, 0.086) explained sexual function. The models proposed for men revealed a more diverse pattern, although the variable essential for explaining sexual function was a positive attitude toward sexual fantasies (ß range = -0.266, -0.097). Conclusions: These results indicate that specific sexual attitudes, particularly in relation to sexual fantasies, are more sensitive variables than erotophilia in examining sexual health.

Association between Psychopathological Dimensions and Sexual Functioning/Sexual Arousal in Young Adults.

Psychological-psychiatric factors have a different effect on sexual functioning in men and women. This research aimed to examine the association between psychopathological dimensions and dimensions of sexual functioning in Spanish young adults in two studies. Study 1 examined sexual functioning and psychopathological dimensions in 700 women and 516 men. Study 2 conducted an experimental laboratory task to evaluate subjective sexual arousal and genital sensations when watching visual sexual stimuli in a subsample of participants from Study 1 (143 women and 123 men). As a result, the first study showed that depression and anxiety-related symptoms had a negative effect, both in men and women, and having a partner had a positive influence on the dimensions of sexual functioning. The second study showed that anxiety symptoms were positively associated with subjective sexual arousal in both men and women, and anxiety was associated with the assessment of genital sensations in men. The differences between the results of anxiety may be explained because sexual arousal was evaluated in general terms in Study 1, whereas it was evaluated as a state in Study 2. These findings confirm that the presence of psychopathological symptoms contributes to sexual functioning, as well as the necessity of strengthening mental illness prevention programs that include sexual health components.

The Impact of Intimate Partner Violence on Sexual Attitudes, Sexual Assertiveness, and Sexual Functioning in Men and Women.

BACKGROUND: Intimate Partner Violence (IPV) causes physical, sexual, or psychological harm. The association between psychosexual (sexual assertiveness, erotophilia, and attitude towards sexual fantasies) and sexual function (sexual desire, sexual excitation, erection, orgasm capacity, and sexual satisfaction), and the experience of physical and non-physical IPV was assessed. METHODS: Data from 3394 (1766 women, 1628 men) heterosexual adults completed the Spanish version of the Index of Spouse Abuse, scales measuring psychosexual and sexual function, and demographic characteristics were collected. RESULTS: For men, poorer sexual health was associated with an experience of physical abuse (F = 4.41, p < 0.001) and non-physical abuse (F = 4.35, p < 0.001). For women, poorer sexual health was associated with physical abuse (F = 13.38, p < 0.001) and non-physical abuse (F = 7.83, p < 0.001). CONCLUSION: The experience of physical or non-physical abuse has a negative association with psychosexual and sexual functioning in both men and women.

Temporal stability and clinical validation of the Spanish version of the female sexual function inventory (FSFI).

The Female Sexual Function Index is one of the most common instruments used to evaluate the female sexual function. The present study aimed to analyze the test-retest reliability, internal consistency, and discriminant validity of the index in clinical samples and to determine a specific and sensitive cutoff point for the Spanish version of the Female Sexual Function Index. For that purpose, a sample consisting of 117 Colombian women was recruited to evaluate test-retest reliability, and a second sample, consisting of 185 women, was divided into diagnosis and no-diagnosis groups based on DSM-5 criteria. Results showed adequate test-retest reliability after four weeks, and satisfactory evidence of internal consistency was obtained for subscale and overall scores. The inventory was found to have an adequate criterion validity, and it confirmed the differences between diagnosis and no-diagnosis groups. The instrument's cutoff point was determined to be 26 points, with a specificity of 73.9%, a sensitivity of 87.7%, and an area under the curve of 85.9 (CI = 80.0-91.7). These results confirm that the Spanish version of the FSFI is an adequate tool for evaluating female sexual dysfunction based on DSM-5 criteria.

The Spanish Version of the Sexual Opinion Survey (SOS-6): Evidence of Validity of a Short Version.

The aim of this work was to provide validity evidences of the short Spanish version of the Sexual Opinion Survey (SOS-6). First, a psychometric study was performed to examine the factorial invariance of the scale across different groups. A sample of 1,500 heterosexual adults (50% men, 50% women) from the general Spanish population, aged 18 to 80, was examined. Results showed that the unidimensional model of the SOS-6 is invariant across sex, age range, relationship status, and educational level. Secondly, a laboratory study was performed to determine the relationship between erotophilia and objective and subjective sexual arousal in response to sexual stimuli. The sample consisted of 130 young Spanish university students (46.92% men, 53.08% women) with heterosexual orientation. In men, erotophilia was related to subjective sexual arousal; in women, erotophilia was related to subjective sexual arousal and estimation of genital sensations. In conclusion, this work provides validity evidences of the short version of the SOS-6 and describes the factorial equivalence of the scale across groups and its concurrent validity.

El objetivo de este trabajo fue aportar evidencias de validez a la versión española breve del Sexual Opinion Survey (SOS-6) mediante dos estudios independientes. En primer lugar, se realizó un estudio psicométrico para examinar la invarianza factorial de la escala por diferentes grupos. Se empleó una muestra de 1.500 adultos heterosexuales (50% hombres, 50% mujeres) de la población española general de entre 18 y 80 años de edad. Los resultados mostraron que el modelo unifactorial del SOS-6 es invariante por sexo, rango de edad, estatus de relación de pareja y nivel de estudios. En segundo lugar, se realizó un estudio de laboratorio para determinar la relación de la erotofilia en la excitación sexual objetiva y subjetiva ante estímulos sexuales. La muestra estuvo compuesta por 130 jóvenes universitarios (46,92% hombres, 53,08% mujeres) de nacionalidad española y con orientación heterosexual. En los hombres, la erotofilia se relacionó con la excitación sexual subjetiva; en las mujeres, la erotofilia se asoció tanto con la estimación de la excitación sexual como con la valoración de sensaciones genitales. Como conclusión, este trabajo aporta evidencias de validez a la versión española breve del SOS-6, mostrando su equivalencia por grupos y su validez concurrente.

Validation of the Sexual Desire Inventory in Colombia.

Sexual desire is a cognitive and affective state that motivates an individual to engage in sexual activity. There are no validated measures to assess this construct in Colombia. The present study aimed to validate the Sexual Desire Inventory (SDI) and explore gender-and age-based differences in sexual desire in Colombian population. The sample was composed of 2,125 men and women who answered the Colombian version of the SDI. Results indicated strict invariance between genders, a three-dimension model, and acceptable validity and reliability indicators. Gender-based and age-based differences were observed in the three types of sexual desire. Implications and conclusions of these findings are presented.

Study of Sexual Satisfaction in Different Typologies of Adherence to the Sexual Double Standard.

The sexual double standard (SDS) refers to the acceptance of different criteria to assess the same sexual behavior in men and women. To date, the few studies that have addressed the relationship between SDS and sexual satisfaction have obtained inconclusive results. In addition, no study has analyzed sexual satisfaction in people who maintain different forms of adherence to the SDS. This study establishes three SDS typologies of adherence (man-favorable, woman-favorable, egalitarian) in two areas of sexual behavior (sexual freedom and sexual shyness) to examine the predictive capacity of personal variables (age, social dominance orientation, propensity for sexual excitation/inhibition), interpersonal variables (relationship satisfaction) and social variables (gender norms about sexual behaviors) in sexual satisfaction. A sample of 1194 heterosexual adults (51.1% men, 48.8% women) aged between 18 and 87 years (M = 40.63; SD = 15.67), who had been in a relationship for more than 6 months, was evaluated. In men, the highest sexual satisfaction levels were obtained in the egalitarian typology in the sexual freedom area. In women, no significant differences were found between the typologies of adherence to the SDS. Regression models showed that relationship satisfaction was the main predictor of sexual satisfaction in all the typologies in both men and women. In addition, the predictive relationship of personal variables with sexual satisfaction varied according to gender and the SDS adherence type. The results show the importance of studying sexual satisfaction by taking into account not only the differences between men and women. Furthermore, it is essential to consider other differences between people; for example, the difference that derives from the way of psychologically internalizing attitude toward the SDS.

Invariance of Spanish version of Sexual Double Standard Scale across sex, age, and education level.

BACKGROUND: The Sexual Double Standard Scale (SDSS) is one of the most widely-used scales for evaluating the Sexual Double Standard (SDS) and the Spanish version of the scale displays adequate psychometric properties in the adult Spanish population. The aim of this study is to examine the factorial invariance and differential item functioning (DIF) of the Spanish version according to sex, education level, and age, with the objective of describing and comparing SDS based on these variables. METHOD: A sample of 3,838 heterosexual participants was used (1,908 men and 1,930 women) between the ages of 18 and 90. RESULTS: The results showed that the factorial structure of the SDSS is invariant in terms of sex and education level; with none of these items displaying DIF. Only items 11 and 14 display DIF in terms of age and, therefore, it is recommended that these items be excluded when making comparisons between age ranges. The association of SDSS with sex, education level, and age follows the expected results. CONCLUSIONS: The Spanish version of the SDSS is invariant and, as a consequence, can be used in different types of samples.

[Connection between subjective sexual arousal and genital response: differences between men and women]. / Relación entre la excitación sexual subjetiva y la respuesta genital: diferencias entre hombres y mujeres.

OBJECTIVE: The level of agreement between subjective and objective measures of sexual arousal is referred as sexual concordance. Sex is one of the principal moderators and there is a higher level of correspondence in men than in women. The aim of this study is to evaluate the predictive validity of the scales Ratings of Sexual Arousal (RSA) and Ratings of Genital Sensations (RGS), relating their scores with the genital response to visual sexual stimuli in men and women. MATERIAL AND METHOD: A sample of 159 young heterosexuals was used (69 men and 90 women) which completed, firstly, a sociodemographic and sexual story questionnaire, the Sexual Inhibition/Sexual Excitation Scales Short-Form and the SOS-6. At the laboratory, they were exposed to a neutral film and to an explicit sexual content film. The subjective sexual arousal was evaluated with the RSA and RGS scales and the genital response was registered through a plethysmography (men) and a photo-plethysmography (women). RESULTS: Significant correlations were obtained between subjective and objective sexual arousal only in men. The RGS scale has the capacity to predict the erection response toward sexual stimuli. CONCLUSIONS: The theory of differences in sexual concordance between men and women was endorsed. Modest evidence about the predictive validity of the subjective sexual arousal evaluation scale was found only in men. It arises the need for subjective and objective assessment of sexual arousal, in clinical settings and research area.

La autoestima sexual: su relación con la excitación sexual / The sexual self-esteem: Its relationship with the sexual arousal

Resumen En este estudio se tuvo como objetivo analizar la relación entre la autoestima sexual (AS) y la excitación sexual como rasgo, estado y componente de la respuesta sexual. La muestra estuvo compuesta por 65 jóvenes heterosexuales que completaron la subescala Excitación Sexual de las Sexual Inhibition/Sexual Excitation Scales-Short Form, el Massachussets General Hospital Sexual Functioning Questionnaire y la subescala Autoestima sexual del Brief Sexuality Scale. A continuación, realizaron una tarea experimental donde completaron las escalas Valoración de Excitación Sexual y Valoración de Sensaciones Genitales tras visualizar un video neutro y otro con contenido sexual explícito. Los resultados mostraron asociaciones significativas entre la AS y la excitación sexual rasgo y la excitación sexual como componente de la respuesta sexual. Ambas manifestaciones de la excitación sexual explicaron un porcentaje significativo de la AS (R 2 = 0,19). Sin embargo, la excitación sexual estado no se asoció con la AS.

Abstract The aim was to analyze the relationship between sexual self-esteem (SSE) and sexual arousal as a trait, as a state and as a component of the sexual response. The sample consisted of 65 heterosexual young people who completed the Sexual Excitation subscale of the Sexual Inhibition/Sexual Excitation Scales-Short Form, the Massachusetts General Hospital Sexual Functioning Questionnaire, and the Sexual Self-esteem subscale of the Brief Sexuality Scale. Participants performed an experimental task where they completed the Ratings of Sexual Arousal and the Ratings of Genital Sensations after visualizing a neutral film and another one with explicit sexual content. The results showed significant associations between SSE and sexual arousal as a trait and as a component of the sexual response. These two types of excitation explained a significant percentage of the SSE (R 2 = 0.19). However, sexual arousal as a state did not correlate to the SSE.
