Adolescence, a period of physical, social, cognitive and emotional development, represents a target population for sexual health promotion and education when it comes to achieving the 2030 Agenda goals for sustainable and equitable societies. The aim of this study is to provide an overview of what is known about the dissemination and effectiveness of sex education programs and thereby to inform better public policy making in this area. Methodology: We carried out a systematic review based on international scientific literature, in which only peer-reviewed papers were included. To identify reviews, we carried out an electronic search of the Cochrane Database Reviews, ERIC, Web of Science, PubMed, Medline, Scopus and PsycINFO. This paper provides a narrative review of reviews of the literature from 2015 to 2020. Results: 20 reviews met the inclusion criteria (10 in school settings, 9 using digital platforms and 1 blended learning program): they focused mainly on reducing risk behaviors (e.g., VIH/STIs and unwanted pregnancies), whilst obviating themes such as desire and pleasure, which were not included in outcome evaluations. The reviews with the lowest risk of bias are those carried out in school settings and are the ones that most question the effectiveness of sex education programs. Whilst the reviews of digital platforms and blended learning show greater effectiveness in terms of promoting sexual and reproductive health in adolescents (ASRH), they nevertheless also include greater risks of bias. Conclusion: A more rigorous assessment of the effectiveness of sexual education programs is necessary, especially regarding the opportunities offered by new technologies, which may lead to more cost-effective interventions than with in-person programs. Moreover, blended learning programs offer a promising way forward, as they combine the best of face-to-face and digital interventions, and may provide an excellent tool in the new context of the COVID-19 pandemic.

The aim of the present study was to develop and validate a short form of the Genderism and Transphobia Scale and assess adolescents' attitudes toward transpeople. A total of 800 Spanish adolescents aged between 14 and 18 years (50.70% girls, 49.30% boys) completed the Spanish version of the scale and other related questionnaires. The short form of the scale is composed of 12 items clustered into two factors (Transphobia/Genderism and Gender Bashing) that explain 54.22% of the variance. All the items showed good discriminating power, and the present scale demonstrated adequate reliability and validity. In the study, boys exhibited significantly more negative attitudes toward transpeople than girls did, both in the affective/cognitive dimension (Transphobia/Genderism) and in the behavioral dimension (Gender Bashing). Moreover, adolescents showed significantly more negative attitudes toward gender-nonconforming men than toward gender-nonconforming women. These results are discussed in terms of their relevance to the maintenance of discriminatory attitudes toward sexual diversity.

Background: Within the context of the widespread use of technologies by adolescents, the objectives of this study were to identify the perpetrators of intimate partner cyberstalking (IPCS) in adolescents; to analyze the relationship between IPCS and gender, age, sexting behaviors, pornography consumption, and ambivalent sexism; and to investigate the influence of the study variables as predictors of IPCS and determine their moderating role. Methods: Participants were 993 Spanish students of Secondary Education, 535 girls and 458 boys with mean age 15.75 (SD = 1.47). Of the total sample, 70.3% (n = 696) had or had had a partner. Results: Boys perform more sexting, consume more pornographic content, and have more hostile and benevolent sexist attitudes than girls. However, girls perpetrate more IPCS than boys. The results of the hierarchical multiple regression indicate that hostile sexism is a predictor of IPCS, as well as the combined effect of Gender × Pornography and Benevolent Sexism × Sexting. Conclusions: it is essential to implement sexual affective education programs in schools in which Information and Communication Technologies (ICT) are incorporated so that boys and girls can experience their relationships, both offline and online, in an egalitarian and violence-free way.

The bullying phenomenon has been simplified and studied primarily from a psychological perspective. In this study, the phenomenon of bullying was examined by analyzing the joint influence of sociocultural factors such as gender stereotypes, sexism, and attitudes toward sexual and cultural diversity on bullying participation as a bully and a bully follower. Participants were 1,165 Spanish and Portuguese adolescents with a mean age of 14.64 years. The hierarchical linear regression model reveals that bullies are less expressive and more instrumental, they hold more hostile sexist and less benevolent sexist attitudes, more negative attitudes toward homosexuality and more positive ones toward lesbianism, as well as more negative behavior toward gender nonconforming people, and more negative attitudes toward cultural diversity. With the exception of expressiveness and negative attitudes toward cultural diversity, these variables also explain participation as a bully follower. Implications for the development of educational policies and practices of bullying prevention are discussed.
