Introducción: Los eventos de vida negativos (EVN) son situaciones estresantes o traumáticas. Los EVN incluyen el divorcio o separación de los padres, y el abuso físico, psicológico o sexual. Se ha sugerido que la relación entre EVN y el consumo de sustancias psicoactivas se atenúa en países de ingresos altos, mientras que en entornos socioeconómicos desfavorecidos, los EVN tendrían un mayor impacto en el consumo de sustancias. Objetivo: Evaluar la asociación entre el número de EVN y el consumo de sustancias psicoactivas en adolescentes y adultos jóvenes urbanos de Buenos Aires-Argentina, Bogotá-Colombia y Lima-Perú. Métodos: Estudio transversal de tipo analítico, con análisis de base secundaria. Los participantes fueron adolescentes y adultos jóvenes de Buenos Aires, Bogotá y Lima residentes en entornos urbanos desfavorecidos. Los datos se recolectaron entre abril de ...

El objetivo de esta investigación fue evaluar la asociación entre nomofobia y calidad de sueño en estudiantes de medicina humana de Perú. Se realizó un estudio con diseño transversal, con muestreo no probabilístico por conveniencia. Participaron 3139 estudiantes de medicina humana de Perú y se recolectaron los datos mediante una encuesta virtual. Para medir nomofobia, se usó el Cuestionario de Nomofobia, y para calidad de sueño se empleó el Índice de Calidad del Sueño de Pittsburgh. Se evaluó la asociación entre nomofobia y calidad de sueño mediante regresión lineal simple. Se encontró que nomofobia se asoció con calidad de sueño (Coeficiente β: 0.02, IC 95% 0.02 - 0.03, p<0.001), específicamente, se halló que por cada unidad adicional en el puntaje de nomofobia, el puntaje de inadecuada calidad de vida aumentó en 0.02. Adicionalmente, se encontró que nomofobia y...

Objectives: The present study aimed to evaluate the measurement invariance of a general measure of the perception of governmental responses to COVID-|19 (COVID-SCORE-10) in the general population of 13 Latin American countries. Methods: A total of 5780 individuals from 13 Latin American and Caribbean countries selected by non-probabilistic snowball sampling participated. A confirmatory factor analysis was performed and the alignment method was used to evaluate invariance. Additionally, a graded response model was used for the assessment of item characteristics. Results: The results indicate that there is approximate measurement invariance of the COVID-SCORE-10 among the participating countries. Furthermore, IRT results suggest that the COVID-SCORE-10 measures with good psychometric ability a broad spectrum of the construct assessed, especially around average levels. Comparison of COVID-S...

The present study explored the predictive capacity of fear of COVID-19 on the intention to be vaccinated against COVID-19 and the influence in this relationship of conspiracy beliefs as a possible mediating psychological variable, in 13 Latin American countries. A total of 5779 people recruited through non-probabilistic convenience sampling participated. To collect information, we used the Fear of COVID-19 Scale, Vaccine conspiracy beliefs Scale-COVID-19 and a single item of intention to vaccinate. A full a priori Structural Equation Model was used; whereas, cross-country invariance was performed from increasingly restricted structural models. The results indicated that, fear of COVID-19 positively predicts intention to vaccinate and the presence of conspiracy beliefs about COVID-19 vaccines. The latter negatively predicted intention to vaccinate against COVID-19. Besides, conspiracy bel...

The present study aimed to apply a network analysis model to provide an exploratory empirical conceptualization of dynamic networks of posttraumatic growth (PTG) symptoms in 7,434 people who experienced the death of a loved one from COVID-19 in 16 Latin American countries. The Post-Traumatic Growth Inventory: Short Form of Eight Items was used. A non-regularized network with partial correlation coefficients was estimated through the ggmModSelect algorithm. The network architecture was analyzed for each country through its local properties and global properties. The results indicated that the networks differed significantly between countries. The core dimensions in the networks were relating to others, personal strength, and life value and opportunities, which were more related dimensions that reinforce the emergence of PTG in all countries. The findings may be useful to motivate research...
