(1) Background: Although the evidence is consistent that vaccines for COVID-19 effectively prevent severe illness or death, the rapid development of vaccines has led to increased beliefs about possible negative consequences and conspiracy theories about the vaccine. Several factors influence whether or not people decide to be vaccinated. Some studies suggest that our perception of what significant others do and think influences our behavior. (2) Methods: This study evaluates the predictive role of beliefs about negative consequences of the COVID-19 vaccine, conspiracy beliefs about this vaccine, and social influence on the intention to vaccinate against COVID-19 in three Latin American and Caribbean countries: Chile, Mexico, and Colombia. Using convenience sampling, 2075 adults from Chile (48.3%), Mexico (27.6%), and Colombia (24.6%) participated by answering an online questionnaire with variables of interest. (3) Results: Despite the differences between countries, the results showed that the proposed model is invariant and explains between 56–66% of the COVID-19 vaccination intent. Specifically, controlling for age, socioeconomic status, political orientation, and educational level, we found that beliefs about the negative consequences of the COVID-19 vaccine were the main predictor followed by social influence. Beliefs in conspiracy theories did not predict vaccination intention (4) Conclusions: Considering these variables in campaigns to boost vaccination intention is discussed.

Lockdown is considered to be a successful strategy for preventing the spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). To predict the behavioral intention to stay under lockdown (BIKL), components of the theory of planned behavior (TPB) and the behavioral indicators of infection were applied. Sampling was conducted between 11 April and 30 May 2020. The objective of the study was to identify factors predictive of BIKL by means of a structural equation model. Method: A correlational and comparative repeated measures study was conducted with a sample of 315 participants from different cities in Mexico. Results: Model indices were χ² = 505.1, SD = 228, p < 0.001, χ²/SD = 2.2, CFI = 0.91, RMSEA = 0.06, and SRMR = 0.06; 47% of BIKL was explained by the variables attitude (β = 0.71, p < 0.001), subjective norm (β = 0.14, p = 0.042), and behavioral control (β = 0.24, p < 0.001). Conclusions: Personal and family work conviction and persuasion are favorable for the maintenance of lockdown, including concepts of civic responsibility, a positive attitude, and a family that supports compliance with lockdown. From a governmental point of view, there is a context that promotes control over the situation and exerts a positive impact on the behavioral intention to stay under lockdown.

Una de las principales consecuencias negativas de la actual pandemia por COVID-19, es el impacto sobre la ansiedad y el estrés. Entre los factores que se deben tomar en cuenta para evaluar la respuesta psicosocial de los deportistas ante el COVID-19, están los factores sociodemográficos, por lo que el objetivo del presente estudio fue analizar si la percepción de estrés depende del sexo y el nivel de rendimiento en deportistas mexicanos durante la pandemia por COVID-19. La muestra de este estudio estuvo conformada por 596 deportistas mexicanos, de ambos sexos (mujeres = 40.4%) y con edades comprendidas entre los 13 y 40 años (M = 22.3, DE = 6.87). Los deportistas contestaron la Perceived Stress Scale (PSS-10) y un cuestionario para indagar sobre aspectos sociodemográficos. Los resultados obtenidos a través de la comparación de grupos, indicaron que las mujeres presentaron niveles superiores de estrés percibido que los hombres. Por otro lado, los deportistas de nivel amateur reportaron niveles más altos que los deportistas profesionales. Los resultados del análisis de diferencia muestran que la percepción de estrés depende del sexo y nivel de rendimiento. Estos resultados podrían utilizarse para incrementar la eficacia de los protocolos aplicados para controlar el estrés durante la pandemia por COVID-19 en deportistas. One of the main consequences of the current COVID-19 pandemic is the impact on anxiety and stress levels. Among the factors that must be taken into account to evaluate the psychosocial impact of COVID-19 on athletes are sociodemographic factors, so the objective of this study was to analyze if the perception of stress depends on gender and performance level in Mexican athletes during the COVID-19 pandemic. The sample of this study was made up of 596 Mexican athletes, of both sexes (women = 40.4%) and aged between 13 and 40 years (M = 22.3, SD = 6.87). The athletes answered the Perceived Stress Scale (PSS-10) and a questionnaire covering socio-demographic data. The results obtained through the comparison of groups, indicated that women presented higher levels of perceived stress than men. On the other hand, amateur athletes reported higher levels of perceived stress than professional athletes. The results of the difference analysis shows that the perception of stress depends on sex and performance level were predictors of perceived stress.

Social confinement involves a series of temporary changes in the habits and lifestyles of individuals, severely affecting their regular activities and schedules and substantially modifying socio-familial behavior (SFB) and sleep quality (SQ). There is no literature reporting the effects of SFB changes on SQ during social confinement due to the COVID-19 outbreak. An observational transversal research design, with group comparison and correlation methods, was used to perform the present study. The results were analyzed as follows: (1) An exploratory factor analysis (EFA); (2) A description of the sample was determined by proportions comparisons of sleep habits between the different variables of interest; and (3) A linear regression model was analyzed to explore the predictive association of the negative effects of social isolation during the COVID-19 pandemic on SFB and SQ. In addition to the global SFB score, two SFB factors were identified as predictors affecting the SQ, SF-Habits, and SF-Emotional scores, suggesting a close balance between daily life activities and sleep health during critical social changes. Furthermore, two main risk factors resulted from the regression analysis: economic concerns and increased alcohol consumption. Therefore, the predictive capacity of economic concerns showed statistical significance in anticipating negative sleep quality scores. Overall, this suggests that sleep quality, economic concerns, schedules, and substance use were associated with the self-perception of coping skills, elucidating the importance of fostering habits related to schedules within the home and ensuring that all family members participate.

Las relaciones de pareja afectan la diversidad, tamaño y contenido del autoconcepto. El modelo de Mattingly et al. (2014) proveniente de una cultura individualista, se enfoca en explicar las afectaciones en el autoconcepto a partir de una relación romántica. El modelo bidimensional explica el incremento y decremento (dirección) en el tamaño y diversidad del autoconcepto y el cambio positivo o negativo (valencia) en el contenido del autoconcepto. Este modelo proporciona cuatro factores con las que se pueden analizar estos cambios: Expansión, Contracción, Limpieza y Corrupción. Objetivo. Esta investigación busca evidencia de validez y confiabilidad en población mexicana del Relational Self-Change Scale, escala que mide el modelo bidimensional propuesto por Mattingly. Método. Utilizando una muestra de 210 personas se realizó un análisis factorial exploratorio basado en correlaciones policóricas y el empleo de un análisis de escalamiento multidimensional. Posteriormente empleando una muestra de 242 participantes se realizó un análisis factorial confirmatorio que permitió contrastar la solución original y la obtenida en esta investigación. Resultados. Los diferentes análisis realizados muestran evidencia de solo dos factores, uno positiva y otro negativo el cual es un modelo más parsimonioso para explicar los cambios en el autoconcepto debido a la relación de pareja. Discusión. Pareciera que la población mexicana, la cual está considerada como una cultura colectivista, tiende a conceptualizar de una manera distinta el fenómeno de la autoexpansión.
