ABSTRACT
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.

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 situación 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 trabajadores 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 superior 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. (AU)
This research evaluated alcohol consumption in the Latin American and Latin Caribbean adult population during COVID-19 confinement, taking into account age and employment status. Non-probabilistic design with convenience sampling, with a sample of 4975 participants. Age, employment status and alcohol consumption were analyzed during confinement and retrospectively before the pandemic. The results show that regardless of the country, young people aged 18-29 decreased consumption during confinement; while the largest increase was in adults aged 45-54 years. Full-time workers consumed more than unemployed people. Full-time and part-time employees decreased their consumption during confinement. Self-employed workers showed significantly higher alcohol consumption than full-time and part-time employees during confinement. It is important to promote policies to prevent alcohol consumption in the workplace. (AU)
