Multidimensional Perceived Self-Efficacy Scale for Children has been developed as an important tool to measure Self-Efficacy in school contexts. The present study assesses the measurement invariance of the MSPSE across two samples of Italian and Colombian adolescents using Multi-sample Confirmatory Factor Analysis. Participants were Italian (N = 564) and Colombian (N = 645) students attending the 7 th grade (age 12-13) drawn from a residential community near Rome and three Colombian cities: Medellin, Manizales and Santa Marta. Findings from gender invariance provide high support for full and partial invariance among Colombian and Italian adolescents respectively. Cross-national comparison showed partial scalar invariance between Italy and Colombia, with Italian students perceiving themselves as more efficacious on Academic, Social and Self-Regulatory dimensions. MSPSE's structural validity has been confirmed, along with its three-factor-structure across gender, for the Italian and Colombian samples. The findings support the invariance and the validity of this scale to measure Self-Efficacy in school contexts from a cross-cultural perspective.

Introduction Recent research highlight increasing at-risk online sexual activities and behaviors during the COVID-19 pandemic among young adults. Specifically, sexting refers to exchanging sexually suggestive messages, photos, and videos through technological devices, and it can be placed on a continuum from safer to riskier behavior. This study aims to improve our knowledge about sexting behaviors in Italian and Colombian young adults before and during the COVID-19 pandemic. Methods A survey online was filled in by all recruited participants through a snowball sampling procedure (from December 2019 to June 2021) both in Italy and Colombia, resulting in a total of 2931 participants (2051 from Italy and 880 from Colombia) aged 18 to 35 years old (Mage = 23.85; SDage = 3.63; 67.6% girls). Results Italian youth were more engaged in risky sexting than Colombian participants, while Colombians indicated being more engaged in non-consensual sexting than Italians. Sexual minority people reported more sharing their own sexts, higher levels of sexting under pressure, and 3.2 times more risky sexting than exclusively heterosexual counterparts. During the pandemic period, participants sent their own sexts 1.5 times more and were less involved in non-consensual sexting than in the pre-pandemic era. Conclusions The present research could help understand better the cultural dynamics underlying the differences in sexting behaviors, suggesting the relevance of investigating how sexting behaviors and online at-risk activities have changed since the pandemic started. Policy Implications Results provide implications for educational and prevention programs to improve young people's awareness of sexting behaviors.

Despite the democratised access to digital media, there are still gaps in uses and opportunities according to age, sex, socioeconomic level, and location. In addition, the study about the use of digital media by children and adolescents has focused more on the risks than on the opportunities. This study analyses the relationship between different uses of digital media (socialisation, socio-political, and learning purposes), with school civic engagement. A sample of 524 students (Mage=12; 43.7% girls) from Santiago de Chile participated. Structural equation modelling with latent variables was used to test a parallel mediation model in which the use of socialisation in digital media is related to school civic engagement, through digital media use for socio political purposes and the digital media use for learning purposes. In addition, multigroup analysis by sex was tested. The main results showed that digital media use for socialisation has a positive effect on school civic engagement through the parallel mediation of digital media use for socio-political purposes and the digital media use for learning purposes. The multigroup analysis showed that mediation is significant in both boys and girls. The results have contributed to the expansion of knowledge about the opportunities of digital media on civic engagement in formal school contexts. A pesar de la democratización del acceso a los medios digitales, siguen existiendo brechas en los usos y oportunidades según edad, género, nivel socioeconómico y localización. Además, estudios sobre usos de medios digitales por parte de niños y adolescentes se han centrado más en riesgos que en oportunidades. Este estudio analiza la relación entre los usos de los medios digitales (socialización, sociopolíticos y aprendizaje), y el compromiso cívico escolar. Participó una muestra de 524 estudiantes (Mage=12; 43,7% niñas) en Santiago de Chile. Se utilizó un modelo de ecuaciones estructurales con variables latentes para probar un modelo de mediación paralelo en el que el uso de los medios digitales para la socialización se relaciona con el compromiso cívico escolar, a través del uso de los medios digitales con fines sociopolíticos y el uso de los medios digitales con fines de aprendizaje. Finalmente, se realizó un análisis multigrupo por sexo. Los resultados mostraron que el uso de medios digitales para la socialización tiene un efecto positivo en el compromiso cívico escolar a través de la mediación paralela del uso de los medios digitales con fines sociopolíticos y el uso de los medios digitales con fines de aprendizaje. El análisis multigrupo mostró que la mediación es significativa tanto en hombres como mujeres. Los resultados amplían el conocimiento sobre las oportunidades de los medios digitales para el compromiso cívico en contextos escolares.

The present study examined the predictive effect of moral disengagement (within and between classrooms) on antisocial behaviors in Colombian adolescents, as well as the interaction of moral disengagement with classroom composition by age, socioeconomic status (SES), and perceived teacher–student relationship quality. Multilevel modeling was used to identify individual, compositional, and contextual effects on antisocial behaviors. The predictive variables were: (a) classroom mean score (i.e., between-classroom analysis), and (b) student deviation from the classroom mean score (i.e., within-classroom analysis). The sample included 879 students nested in 24 seventh-grade classrooms in three Colombian cities. The results showed that age, SES, and moral disengagement at the within-classroom level predicted antisocial behaviors. At the between-classroom level, antisocial behaviors were predicted by higher moral disengagement and lower aggregate SES. In addition, significant interactions were found between moral disengagement at the within-classroom level and SES at the between-classroom level. The findings expand our knowledge of the interdependence between individual and classroom contexts in the exercise of moral agency during adolescence.
