A Validation Study of the German Version of the Sexual Inhibition/Sexual Excitation Scales-Short Form

A Psychometric Study of a Trait and State Assessment of Sexual Pleasure - The Amsterdam Sexual Pleasure Inventory

We studied the Amsterdam Sexual Pleasure Inventory's (1.0) psychometric properties. The ASPI, a revised self-report battery designed to measure domains of state and trait sexual pleasure in diverse gender, sex, and relationship populations, is based on a recently proposed conceptual framework of sexual pleasure. We collected quantitative (n = 1371) and qualitative data (n = 637) using a cross-sectional multi-method design targeting the general (German-speaking) population. After pre-processing, we conducted analyses on a sample of n = 706 participants. The theory-based 5-factor exploratory structural equation model and the principal component analyses of the two general exploratory index-scales showed good and acceptable structural validity evidence respectively. Measurement invariance was confirmed separately for male and female participants and for those with sexually functional-scoring and dysfunctional-scoring levels. Coefficient omega indicated that all scales, except those of one facet, showed acceptable to very good internal consistency. The ASPI's convergent and discriminant associations with sexological and psychological constructs demonstrated good overall construct validity. Participants understood the items as intended and felt that the ASPI covered relevant facets of sexual pleasure. The ASPI might help understand how individuals differ in experiencing sexual pleasure and how different contexts enable some people to experience pleasure while disadvantaging others.

Sexual Excitation and Inhibition Moderate the Strength of Concordance Between Paraphilic Interests and Behaviors

The concordance between paraphilic interest and behavior is moderate to strong in previous studies. In the present study, we examined whether sexual excitation (SE) and sexual inhibition (SI) moderate the concordance between paraphilic interest and behavior, across several paraphilic themes. We expected that stronger concordance would be found at high levels of SE and weaker concordance would be found at high levels of SI, for both men and women. We expected stronger effects when high levels of SE are combined with low levels of SI and when low levels of SE are combined with high levels of SI, for both genders. To test this, we sampled 219 men and 351 women (Mage = 28.42, SDage = 10.58) and conducted moderated moderation analyses with bootstrapping, separately for each gender and paraphilic theme. Consistent with our hypotheses, for paraphilic themes where SE was a significant moderator, the concordance between paraphilic interest and behavior was stronger at higher levels of SE. In contrast, for themes moderated by SI, the concordance was weaker at higher levels of SI. Sexual excitation and sexual inhibition only moderated concordance between paraphilic interest and behavior for masochism and voyeurism in women, in the expected direction: the highest concordance was observed at higher SE/lower SI and the lowest concordance was observed at lower SE/higher SI. SE and SI moderated concordance between paraphilic interest and behavior across several different paraphilic themes for men and women, suggesting that different sexuality traits may be involved across genders and across themes.

Interplay between sexual excitation and inhibition: impact on sexual function and neural correlates of erotic stimulus processing in women

Background

As outlined by the dual control model (DCM), individual differences in the regulation of sexual arousal following sexual stimulation depend on two distinct neurophysiological processes: sexual excitation (SE) and sexual inhibition (SI). Although associations with sexual function, behavior, and cue processing have been demonstrated in previous research, underlying neural correlates remain insufficiently explored. Moreover, interactive effects of SE/SI as proposed by the DCM, as well as factors impacting SE/SI properties, such as the use of oral contraceptives (OCs), have not received adequate attention in existing research.

Methods

90 healthy, sexually active women (n = 51 using OCs, n = 39 naturally cycling) completed an Emotional-Picture-Stroop-Paradigm (EPSP) while a 64-channel EEG was recorded. LPP amplitudes toward erotic and neutral stimuli were consecutively computed as a marker of motivational salience and approach motivation. Additionally, women provided self-reports of SE/SI and sexual function. Moderation analyses were performed to assess interactive effects of SE/SI in predicting LPP amplitudes and sexual function.

Results

Sexual function was negatively associated with SI levels but unrelated to SE. Higher SI was associated with reduced LPP amplitudes in response to erotic stimuli. This negative association was, however, attenuated for women high in SE, suggesting interactive effects of SE/SI. Furthermore, women using OCs reported lower SE compared to naturally cycling women.

Conclusion

The observed findings provide additional psychophysiological evidence supporting the DCM and underscore the relevance of interactive SE/SI effects in stimulus processing and approach motivation. They also highlight the possible impact of OCs on psychosexual variables that warrants further research.

The Dual Control Model of Sexual Response: A Scoping Review, 2009-2022

The Dual Control Model proposes that sexual arousal and related processes are dependent on the balance between sexual excitation and sexual inhibition, and that individuals vary in their propensity for these processes. This scoping review provides an overview and discussion of the questionnaires used to measure the propensities for sexual excitation and inhibition, their translation and validation in other languages, and their application in empirical research on topics ranging from sexual desire and arousal, sexual (dys)function, sexual risk taking, asexuality, hypersexuality, and sexual aggression. A total of 152 papers, published between 2009 and 2022 and identified using online databases, were included in this review. The findings, consistent with those reviewed by Bancroft et al. (2009), suggest that sexual excitation is particularly relevant to sexual desire and responsivity and predictive of asexuality and hypersexuality. Sexual inhibition plays a role in sexual dysfunction. sexual risk taking, and sexual aggression, although often in interaction with sexual excitation. Suggestions for the further development of the model and for future studies are discussed.

Premature Ejaculation Symptoms Are Associated with Sexual Excitability: Empirical Support for the Hyperarousability Model

Premature ejaculation (PE) is a common sexual complaint among men, but its etiology is poorly understood. Previous studies on the dual control model of sexuality has revealed that propensities for sexual excitation and inhibition can contribute to sexual dysfunctions, but few studies have included a measure of premature ejaculation. We sought to explore whether PE is associated with sexual excitation or inhibition. We applied structural equation models to data from a large population-based sample of Finnish adult men. The analyses supported a four-factor solution for the sexual inhibition/sexual excitation short-form scale. The clearest result was that increased symptoms of PE were associated with a greater propensity for sexual excitation (β = 151, p < 001, n = 2953). Importantly, this excitation was intrapersonal, as opposed to stemming from social activities. The results imply that men with PE may have stronger and more rapid reactions to sexual stimuli, which in turn may lead to ejaculating earlier than desired.

Validation of the Sexual Inhibition/Sexual Excitation Scales (SIS/SES) in Italy: Assessing Gender and Age Differences of Sexual Functioning

The Sexual Inhibition Scales and Sexual Excitation Scales (Janssen et al., 2002a), based on the dual control model by Bancroft and Janssen (2000), are part of a 45-item self-report questionnaire evaluating individual tendencies to sexual inhibition or excitation according to three factors: two inhibition factors, SIS1, threat of performance failure, and SIS2, threat of performance consequences, and one excitation factor, SES. In this paper, we aimed to validate and explore psychometric properties of the SIS/SES in a sample of 2260 Italian men and women aged 18 to 75 years. Confirmatory factor analyses showed that the three-factor structure proposed in the original version of the scales fit with our sample. Moreover, our data confirmed the results of the original validation sample: Women scored higher on the SIS and lower on the SES than men did, but no significant differences appeared in the factor scores by age group, except for a gender × age interaction, where younger women had higher SIS2 scores. The SIS/SES appeared to be an effective, appropriate cross-cultural measurement of human sexuality in Italian samples, also shedding light on sexual arousal differences in women and men in our country. We also discuss clinical and therapeutic aspects.

Validation of the French-Canadian Version of the Sexual Inhibition and Sexual Excitation Scales-Short Form (SIS/SES-SF): Associations With Sexual Functioning, Sociosexual Orientation, and Sexual Compulsivity

Introduction

The Dual control model proposes that both excitatory and inhibitory processes are responsible for the human sexual response.

Aim

To validate the French-Canadian translation of the Sexual Inhibition and Excitation Scales-Short Form (SIS/SES-SF) by exploring its factor structure and by investigating its capacity to retrospectively predict sexual functioning and behaviors, namely, sociosexual orientation and sexual compulsivity.

Methods

A French-Canadian translation of the SIS/SES-SF was created using forward-backward translation. A community sample of 362 men and 420 women completed an online survey. The factor structure and the measurement invariance between men and women was explored using Exploratory Structural Equation Modeling. Predictive power of the scales was tested using Multiple Linear Regression models using a corrected threshold (P< .008).

Main outcome measures

Sexual functioning was assessed using the International Index of Erectile Function and the Female Sexual Function Index while sexual compulsion and sociosexual orientation were measured using the Sexual Compulsion Scale and the Revised Sociosexual Orientation Inventory, respectively.

Results

The original three-factor solution of the SIS/SES-SF was replicated. All three scales showed acceptable internal consistency and good temporal stability. Yet, results only supported configural measurement invariance between men and women, suggesting that their scores cannot be directly compared. Overall, for both men and women, higher sexual excitation (SES) was significantly predictive of better sexual functioning, while higher sexual inhibition due to threat of performance failure (SIS1) was a significant predictor of lower sexual functioning. Both sexual compulsivity and sociosexual orientation were significantly predicted by higher SES and lower sexual inhibition due to threat of performance consequences (SIS2).

Conclusion

These results support the cross-cultural transferability of the SIS/SIS-SF and the Dual control model to French-Canadian men and women, higlighting the utility for clinicians to evaluate both excitatory and inhibitory factors associated with sexual dysfunction and sexual behaviors.

Validación de las Escalas de Inhibición y Excitación Sexual (SIS/SES-SF) en colombianos

Las escalas SIS/SES-SF han sido desarrolladas para medir la inhibición y la excitación sexual. El objetivo del presente estudio fue adaptar y validar estas escalas en población colombiana. Para esto, se realizó la adaptación cultural y validación de contenido de las escalas por medio del juicio de siete expertos, y se validaron psicométricamente sobre una muestra de 2125 participantes (1000 hombres y 1125 mujeres). Los hombres contestaron al International Index of Erectile Function y la Premature Ejaculation Diagnostic Tool; mientras que el total de la muestra contestó al Sexual Desire Inventory, al Massachusetts General Hospital-Sexual Functioning Questionnaire y a la Sexual Inhibition/Sexual Excitation Scales-Short Form, todo ello junto a una batería sociodemográfica. El muestreo se realizó de forma virtual a través de Facebook. Los índices de las escalas mostraron una apropiada validez y fiabilidad. Además, para ambos sexos, las escalas mostraron un nivel de invarianza estricto. Las relaciones significativas con las otras medidas dan cuenta de su validez de criterio. Se sugiere el uso del instrumento para continuar con la investigación del Modelo de Control Dual dentro de la sexualidad en Latinoamérica.
