Funcionamiento sexual en personas mayores: influencia de la edad y de factores psicosexuales

Measurement Invariance across Sexual Orientation for Measures of Sexual Attitudes

Despite the growing interest in the study of sexual attitudes across sexual orientation, few studies have tested whether the instruments used to measure them are invariant. This study examined measurement invariance (configural, weak, strong, and strict) across sexual orientation in three different sexual attitude scales: the Sexual Opinion Survey (SOS) to assess erotophilia, the Hurlbert Index of Sexual Fantasy (HISF) to assess attitudes toward sexual fantasies, and the Negative Attitudes Toward Masturbation Inventory (NATMI) to assess negative attitudes toward masturbation. A total of 2293 Spanish adult men and women with different sexual orientations (i.e., heterosexual, bisexual, and gay) participated in the study. The results indicated strict invariance for HISF across sexual orientation and only weak invariance for SOS and NATMI. Differential item functioning was also found in two items of the NATMI scale. Evidence of validity was provided for the three scales that were studied.

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 (β = 0.15), current masturbation frequency (β = 0.18) and negative attitude towards masturbation (β = 0.17) explained 8% of the difficulty in orgasmic facility, and another in which age (β = 0.14) and negative attitude towards masturbation (β = 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 (β = -0.22) and 15% of orgasm satisfaction (β = -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.

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 (β range = -0.35, -0.249) and age (β 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 (β 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.

Mindfulness in Sexual Activity, Sexual Satisfaction and Erotic Fantasies in a Non-Clinical Sample

The goal of this study is to better understand the relation between the practice of Mindfulness and the sexual activity, sexual satisfaction and erotic fantasies of Spanish-speaking participants. This research focuses on the comparison between people who practice Mindfulness versus naïve people, and explores the practice of Mindfulness and its relation with the following variables about sexuality: body awareness and bodily dissociation, personal sexual satisfaction, partner and relationship-related satisfaction, desire, subjective sexual arousal, genital arousal, orgasm, pain, attitudes towards sexual fantasies and types of sexual fantasies. The sample consisted of 106 selected adults, 32 men and 74 women, who completed six measures on an online survey platform: (a) Mindfulness Attention Awareness Scale (MAAS), (b) Scale of Body Connection (SBC), (c) New Sexual Satisfaction Scale (NSSS), (d) Scale of Sexual Activity in Women (SSA-W) and Men (SSA-M), (e) Hurlbert Index of Sexual Fantasy (HISF), (f) Wilson's Sex Fantasy Questionnaire. In the MAAS, Body Awareness subscale (SBC), NSSS, SSA-W and SSA-M, HISF and intimate fantasies subscale (Wilson's questionnaire), people in the Mindfulness condition showed higher scores and these differences were statistically significant. These results may have relevant implications in the sexuality of clinical and non-clinical samples.

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.

Sexual desire and its relationship with subjective orgasm experience

Orgasm and sexual desire are components of the human sexual response. The main objective of this study was to examine the relationship between the sexual desire and dimensions of the subjective orgasm experience. A sample composed of 1161 heterosexual adults, distributed into three age groups (18-34, 35-49, and 50 years old or older), completed a background questionnaire, the Orgasm Rating Scale, and the Sexual Desire Inventory. First, the effect that sex and age have on the subjective orgasm experience was analyzed. Second, correlations between sexual desire and orgasm experience were examined. Also, the predictive capacity that dimensions of sexual desire have on the subjective orgasm experience in the context of sexual relationship was examined. Results showed that age had a significant effect on the intensity of the subjective orgasm experience perceived during sexual relationships with a partner and that this experience decreased as people get older. There was an association between the components of sexual desire and the dimensions of subjective orgasm experience. Furthermore, partner-focused sexual desire contributed in a relevant manner to the subjective orgasm experience. Implications for both research and clinical field are also discussed.

Evidence for the validity of the Attitudes Toward Sexual Behaviours Scale (ASBS) with Canadian young people

It is important to have psychometrically sound measures of various types of sexual attitudes because sexual attitudes are related to sexual health and sexual behaviour. There are few measures focused on attitudes toward sexual behaviours. In addition, existing measures do not include items that assess online sexual behaviours and/or the context in which sexual behaviours occur. The Spanish Attitudes Toward Sexual Behaviours Scale (ASBS) fills this gap. The goal of the current study was to develop an English version of the ASBS (ASBS-E), and evaluate its psychometric properties in a sample of Canadian young people. A total of 209 participants ranging in age from 18 to 30 years (71.7% female) completed an online survey. The survey included the ASBS-E and measures of religiousity, erotophobia-erotophilia, sexual permissiveness, sexual experience and interest, frequency of use of pornography, and social desirability. The confirmatory factor analysis suggested that the factor structure of the ASBS-E is similar to that of the ASBS – that is, five first-order factors and a unique second-order factor. The results indicated that the ASBS-E has good psychometric properties. Specifically, the reliability estimated by Cronbach's alpha, omega, and split-half method was good. In addition, consistent with predictions, ASBS-E total scores were positively correlated with sexual attitudes and sexual behaviours measures, negatively correlated with measures of religiousity, and unrelated to social desirability, supporting the scale's convergent and discriminant validity. Thus, this scale can be used to to predict contextualized and varied sexual behaviours in clinical and educational contexts.

[Systematic review of the subjective experience of orgasm]

Orgasm is an essential component of the sexual response. Its study has generated results that point out its importance in human sexuality. The aim of the present study was to review the subjective orgasm experience, its evaluation and its association with personal, interpersonal and psychosocial variables. After conducting a literature search in major databases, we provide a total of 121 scientific articles published between 2000 and 2016, in which the subjective orgasm experience was the main variable. The analysis of the related variables shows that personal variables (for example, health and demographic factors) and interpersonal variables (for example, sexual functioning) are the most considered. To conclude, we observe the need to develop standardized instruments to evaluate specifically the subjective orgasm experience and the need to study jointly the associated variables in order to propose explanatory models of orgasm that are useful for clinical practice.

Spanish version of the Sexual Excitation/Sexual Inhibition Inventory for Women: Factorial structure, reliability and validity evidences

Background/Objective: The Dual Control Model suggests that sexual excitation and associated behaviors are the result of the balance between relatively independent excitatory and inhibitory mechanisms. Based on this theoretical model, the Sexual Excitation/Sexual Inhibition Inventory for Women (SESII-W) was developed to evaluate excitation and inhibition dimensions in women. The aim was to adapt and validate the SESII-W in the Spanish population. Method: A sample of 1,380 heterosexual women (aged 18 to 52) completed the Spanish SESII-W, together with other related instruments. After the translation and adaptation of the SESII-W, a Confirmatory Factor Analysis (CFA) was performed. Results: CFA resulted in a version consisting of 33 items divided into eight sub-factors, which were grouped into two higher-order factors (Sexual Excitation and Sexual Inhibition). The sub-factors demonstrated adequate internal consistency values except for Sexual Power Dynamics and Concerns about Sexual Function. Test-retest reliabilities were good. Their scores correlated with erotophilia, sexual sensation seeking, age at first intercourse, and number of sexual partners in the expected direction. Conclusions: The Spanish version of SESII-W has adequate psychometric guarantees for use in clinical practice and research, although it would be necessary to further revise factors that showed a lower level of reliability.

Influence of substance use on the erectile response in a sample of drug users

Erectile dysfunction in men may be due to multiple causes, including anxiety and substance abuse. The main objective of this study is to know how it affects the continued use of addictive substances in the erectile response, taking into account not only the type of substances consumed, but also other variables that may influence on sexual response, such as the time of withdrawal, anxiety and sexual attitude. Two samples were used, one for males (n = 925) who had a history of substance use and another one for males (n = 82) with no history of substance abuse. Both populations were selected by a cluster sampling of 27 Spanish provinces. The GRISS, SOS and STAI questionnaires were used. The results indicate that men with a history of consumption obtained a higher percentage of dysfunction in the erectile dysfunction questionnaire GRISS scale than those who have a history of consumption (36.69% vs.15.85%) who also have higher scores on state anxiety (19.83 vs.11.89) and trait anxiety (25.66 vs.12.39) and lowest in erotophilia (86.85 vs. 97.29) was statistically significant difference. It is also proved that the time of withdrawal does not help ex drug users improve their erectile response.
