Love is a phenomenon that occurs across the world and affects many aspects of human life, including the choice of, and process of bonding with, a romantic partner. Thus, developing a reliable and valid measure of love experiences is crucial. One of the most popular tools to quantify love is Sternberg’s 45-item Triangular Love Scale (TLS-45), which measures three love components: intimacy, passion, and commitment. However, our literature review reveals that most studies (64%) use a broad variety of shortened versions of the TLS-45. Here, aiming to achieve scientific consensus and improve the reliability, comparability, and generalizability of results across studies, we developed a short version of the scale—the TLS-15—comprised of 15 items with 5-point, rather than 9-point, response scales. In Study 1 (N = 7,332), we re-analyzed secondary data from a large-scale multinational study that validated the original TLS-45 to establish whether the scale could be truncated. In Study 2 (N = 307), we provided evidence for the three-factor structure of the TLS-15 and its reliability. Study 3 (N = 413) confirmed convergent validity and test–retest stability of the TLS-15. Study 4 (N = 60,311) presented a large-scale validation across 37 linguistic versions of the TLS-15 on a cross-cultural sample spanning every continent of the globe. The overall results provide support for the reliability, validity, and cross-cultural invariance of the TLS-15, which can be used as a measure of love components—either separately or jointly as a three-factor measure.

This article explores the importance of integrating socio-emotional competencies into the formal education of adolescents to promote sustainable development. It argues that social and emotional learning (SEL) not only enhances personal and academic well-being, but also facilitates the building of more resilient and sustainable communities. A scoping review was conducted using a qualitative methodology based on document analysis through matrix-based reviews. The 49 selected studies were analyzed in relation to the personality facets of the Big Five (OCEAN) model. The results of the interventions show improvements in self-efficacy, empathy, motivation, school climate, bullying reduction, and the prevention of mental health issues. It is concluded that a more holistic approach is needed, combining SEL with character education to achieve lasting impacts. Furthermore, interventions must be sensitive to cultural contexts and the specific realities of each school community.

In the last decades, the importance of argumentation as a human competence in general and its close relationship with mathematical comprehension in particular has been highlighted. Thus, in this paper we focus our interest on analyzing the argumentation skills shown by three-year-old children in a STEAM classroom experience. For this purpose, a qualitative study was carried out. For data collection, a STEAM task has been designed in which mathematics and science are worked together from the study of the physical properties of water. Specifically, what color and taste of water has by means of two experiments and, subsequently, photos and video-recordings have been collected during the implementation carried out in a classroom with 20 children of three-year-old. All data collect have subsequently been transcribed and categorized. The results indicate that the children, during the experiments done, mainly use arguments based on mathematical language, numerical figures, or make use of words or spelling, although with considerable imprecision in the type of language used. In addition, the experiments carried out have allowed a high percentage of children to change their previous ideas and have a more comprehensive approach to the concepts introduced, highlighting the importance of working on argumentation in early childhood education through contexts, in this case STEAM, which encourage reasoning and proof.

(1) Problematic Internet use (PIU) in young people is a topic of great interest both in the field of addictions and mental health, but scientific evidence is limited in Latin America. The aim was to analyze the relationship between PIU and depression in Latin American college students. (2) Methods: The sample consisted of 1828 college students (63.7% women), aged between 18–30 years (M = 21.64 years). (3) Results: PIU was detected in 40.2% of cases, and severe or moderately severe depression in 31.7%. Rates of severe depression in students with PIU were 3.02 times higher than in those without PIU (χ2(3) = 168.443; p < 0.000). The presence of PIU was also statistically significantly higher among youth with depressive symptoms. Linear and logistic regression models for predicting PIU, show how the depression level constitutes a risk factor for PIU: seven times higher for severe depression; more than five times higher for moderate depression; and more than two times for mild depression. (4) Conclusions: There is a clear association between depression and PIU, suggesting that a higher level of depression would act as a predictor of PIU. However, this finding is exploratory. Future studies should clarify the directionality of the relationship between both variables.

Esta investigación evaluó el consumo de alcohol en población adulta Latinoamericana y del Caribe latino durante el confinamiento por COVID-19, atendiendo a la edad y situ- ación laboral. Diseño no probabilístico con muestreo por conveniencia, con una muestra de 4975 participantes. Se analizó edad, situación laboral y consumo de alcohol durante el confinamiento y retrospectivamente antes de la pandemia. Los resultados muestran que independientemente del país, los jóvenes de 18-29 años disminuyeron el consumo durante el confinamiento; mientras que el mayor aumento fue en adultos de 45-54 años. Los traba- jadores a tiempo completo consumieron más que las personas desempleadas. Empleados a tiempo completo y a tiempo parcial, disminuyeron su consumo durante el confinamiento. Trabajadores por cuenta propia mostraron un consumo de alcohol significativamente supe- rior al de empleados a tiempo completo y a tiempo parcial, durante el confinamiento. Es importante impulsar políticas de prevención del consumo de alcohol en el ámbito laboral.
