Design and Cross-Cultural Invariance of the COVID-19 Vaccine Conspiracy Beliefs Scale (COVID-VCBS) in 13 Latin American Countries
(Frontiers Media S.A., 2022-06-14) Caycho-Rodríguez, Tomás; Valencia, Pablo D.; Ventura-León, José; Vilca, Lindsey W.; Carbajal-León, Carlos; Reyes-Bossio, Mario; White, Michael; Rojas-Jara, Claudio; Polanco-Carrasco, Roberto; Gallegos, Miguel; Cervigni, Mauricio; Martino, Pablo; Palacios, Diego Alejandro; Moreta-Herrera, Rodrigo; Samaniego-Pinho, Antonio; Lobos-Rivera, Marlon Elías; Buschiazzo Figares, Andrés; Puerta-Cortés, Diana Ximena; Corrales-Reyes, Ibraín Enrique; Calderón, Raymundo; Pinto Tapia, Bismarck; Arias Gallegos, Walter L.; Petzold, Olimpia
“Aims: Over the past 2 years, the vaccine conspiracy beliefs construct has been used in a number of different studies. These publications have assessed the determinants and outcomes of vaccine conspiracy beliefs using, in some cases, pooled data from different countries, and compared the results across these contexts. However, studies often do not consider measurement invariance as a necessary requirement for comparative analyses. Therefore, the aim of this study was to develop and evaluate the crosscultural MI of the COVID-19 Vaccine Conspiracy Beliefs Scale (COVID-VCBS) in 12 Latin American countries. Methods: Confirmatory factor analysis, item response theory analysis and alignment method were applied to test measurement invariance in a large number of groups. Results: The COVID-VCBS showed robust psychometric properties and measurement invariance for both factor loadings and crosstabs. Also, a higher level of acceptance of conspiracy beliefs about vaccines is necessary to respond to higher response categories. Similarly, greater acceptance of conspiracy beliefs about COVID-19 vaccines was related to a lower intention to be vaccinated. Conclusion: The results allow for improved understanding of conspiracy beliefs about COVID-19 vaccines in the countries assessed; furthermore, they provide researchers and practitioners with an invariant measure that they can use in cross-cultural studies in Latin America. However, further studies are needed to test invariance in other countries, with the goal of developing a truly international measure of conspiracy beliefs about COVID-19 vaccines.“

(Frontiers Media S.A., 2022-12-20) Reyes-Bossio, Mario; Corcuera-Bustamante, Santiago; Veliz-Salinas, Giancarlo; Villas Boas Júnior, Marcelo; Delgado-Campusano, Mariel; Brocca-Alvarado, Paul; Caycho-Rodríguez, Tomás; Casas-Apayco, Leslie; Tutte-Vallarino, Verónica; Carbajal León, Carlos; Brandao, Regina
Introduction: Intervention programs in sports psychology aid to modify the thoughts and behaviors of athletes in order to improve their performance in sports settings. For high-performance athletes, these interventions are very relevant, given that they constantly face pressure towards obtaining sporting achievements. Methods: This systematic review aims to analyze the scientific articles between 2010 and 2020 that evaluated the eect of psychological interventions on high-performance athletes. In the search procedure, nine studies were selected, the most studied variables were psychological skills, psychological flexibility, and stress. Results: The 44% of the interventions were designed by the research authors themselves, while the remaining 56% were replicated programs, which already had scientific evidence. Discussion: Psychological interventions have a positive impact on sports performance. This review allows sports institutions and professionals to have more knowledge and resources at their disposal to implement these types of programs in their sports plannin

Impact of COVID-19 on quality of life in Peruvian older adults: construct validity, reliability and invariance of the COV19-Impact on Quality of Life (COV19-QoL) measurement
(SPRINGER INT PUBL AG, 2023-05-22) Caycho-Rodríguez, Tomás; Carbajal-León, Carlos; Vilca, Lindsey W; Reyes-Bossio, Mario; Gallegos , Miguel; Carranza Esteban , Renzo; Noe-Grijalva, Martin; Arias Gallegos, Walter L; Delgado-Campusano, Mariel; Muñoz-Del-Carpio-Toia, Águeda
The aim of the present study was to translate into Spanish and evaluate the psychometric evidence of the Impact on Quality of Life (COV19-QoL) applied to a sample of Peruvian older adults (N = 298; 58.1% women, 41.9% men, mean age 65.34 years [SD = 11.33]). The study used techniques from the Classical Test Theory (CTT) and Item Response Theory (IRT). The findings confirmed the single factor structure of the COV19-QoL, high internal consistency reliability, measurement invariance by gender, and all items demonstrated adequate discrimination and difficulty indices. In this sense, the items allow adequate discrimination between low, medium and high levels of the impact of the COVID-19 pandemic on quality of life. In addition, a greater perceived impact of the pandemic on quality of life is necessary to answer the higher response options of the COV19-QoL. In conclusion, the COV19-QoL is a valid measurement scale of the impact of the COVID-19 pandemic on the quality of life of Peruvian older adults.

Is the meaning of subjective well-being similar in Latin American countries? A cross-cultural measurement invariance study of the WHO-5 well-being index during the COVID-19 pandemic
(BioMed Central Ltd, 2023-04-06) Caycho-Rodríguez, Tomás; Vilca, Lindsey W; Valencia , Pablo D; Carbajal-León, Carlos; Reyes-Bossio, Mario; White, Michel; Rojas-Jara, Claudio; Polanco-Carrasco, Roberto; Gallegos, Miguel; Cervigni , Mauricio; Martino, Pablo; Palacios, Diego Alejandro; Moreta-Herrera , Rodrigo; Samaniego-Pinho, Antonio; Lobos-Rivera, Marlon Elías; Buschiazzo Figares, Andrés; Puerta-Cortés, Diana Ximena; Corrales-Reyes, Ibraín Enrique; Calderón, Raymundo; Franco Ferrari, Ilka; Flores-Mendoza, Carmen
“Background: There is an urgent need to assess changes in well-being on a multinational scale during the COVID-19 pandemic, thus culturally valid scales must be available. Methods: With this in mind, this study examined the invariance of the WHO well-being index (WHO-5) among a sample of 5183 people from 12 Latin Americans countries (Argentina, Bolivia, Chile, Colombia, Cuba, Ecuador, El Salvador, Guatemala, Mexico, Paraguay, Peru, and Uruguay). Results: The results of the present study indicate that the WHO-5 is strictly invariant across samples from different Latin American countries. Furthermore, the results of the IRT analysis indicate that all items of the WHO-5 were highly discriminative and that the difficulty required to respond to each of the five items is ascending. Additionally, the results indicated the presence of moderate and small size differences in subjective well-being among most countries. Conclusion: The WHO-5 is useful for assessing subjective well-being in 12 Latin American countries during the COVID-19 pandemic, since the differences between scores can be attributed to differences in well-being and not in other characteristics of the scale.“

Measurement Invariance of the Short UCLA Loneliness Scale in Spanish and Peruvian Old People: Latent Mean Differences and Evidence for Differential Effects on Perceived Health
(South-West University Neofit Rilski, 2023) Caycho-Rodríguez, Tomás; Tomás, José M.; VenturaLeón, José; García Cadena, Cirilo H.; Reyes-Bossio, Mario; Moreta-Herrera, Rodrigo; Vilca, Lindsey W.
“The objectives of this study are to evaluate the measurement invariance of the University of California Los Angeles Loneliness Scale (UCLA-LS) three-item version (UCLA-LS-3) in older adults in Peru and Spain, to compare the latent means of loneliness, and to evaluate the psychometric properties of the scale with Item Response Theory (IRT) models, and evaluate the possible moderating effects of the country on loneliness-health relationships. Peruvian sample was composed of 235 old adults from the city of Lima. The Spanish sample was composed of 443 old adults. The three-factor structure of RUCLA-3 anchored to the health measure fitted the data reasonably well in Spain and Peru. The R-UCLA-3 may be considered invariant for these two samples. The latent means of loneliness are different, the Peruvian average of loneliness being greater than that of Spain. The R-UCLA-3 is an invariant measure in older adults in Peru and Spain, with adequate psychometric properties through IRT models.“

Network analysis of the relationships between conspiracy beliefs towards COVID-19 vaccine and symptoms of fear of COVID-19 in a sample of latin american countries
(SPRINGER, 2022-09-07) Caycho-Rodríguez, Tomás; Ventura-León, José; Valencia, Pablo D.; Vilca, Lindsey W.; Carbajal-León, Carlos; Reyes-Bossio, Mario; Delgado-Campusano, Mariel; Rojas-Jara, Claudio; Polanco-Carrasco, Roberto; Gallegos, Miguel; Cervigni, Mauricio; Martino, Pablo; Palacios, Diego Alejandro; Moreta-Herrera, Rodrigo; Samaniego-Pinho, Antonio; Lobos Rivera, Marlon Elías; Buschiazzo Figares, Andrés; Puerta-Cortés, Diana Ximena; Corrales-Reyes, Ibraín Enrique; Calderón, Raymundo; Pinto Tapia, Bismarck; Arias Gallegos, Walter L.; Petzold, Olimpia
“The present study examined how conspiracy beliefs about COVID-19 vaccines specifcally relate to symptoms of fear of COVID-19 in a sample of four South American countries. A total of 1785 people from Bolivia, Colombia, Ecuador, and Peru participated, responding to a sociodemographic survey, the Fear of COVID-19 scale (FCV-19 S) and the Vaccine Conspiracy Beliefs Scale-COVID-19 (VCBS-COVID-19). Network analysis identifed the most important symptoms of fear and conspiracy beliefs about COVID-19 vaccines (nodes) and the associations between them (edges). In addition, the robustness of the network of these indicators of centrality and the possible diferences in the structure and connectivity of the networks between the four countries were evaluated. The results suggest that the nodes with the highest centrality were items 2 and 5 of the FCV-19 S and item 2 of the VCBS-COVID-19. Likewise, item 6 is the belief that most predicts conspiracy beliefs about vaccines against COVID-19; while item 6 was the symptom that most predicts fear of COVID-19. The fndings strongly support cross-cultural similarities in the networks across the four countries rather than diferences. Although it was expected that a higher presence of symptoms of fear of COVID-19 may lead people to compensate for their fear by believing in conspiratorial ideas about vaccines and, consequently, rejecting the COVID-19 vaccine, the results do not clearly show this relationship. This could lead other researchers to generate evidence to explain the diferences between Latin American countries and countries in other contexts in terms of vaccination rates. This evidence could be useful to develop policies favoring vaccination against COVID-19 that are more contextualized to the Latin American region, characterized by social instability and economic recession during the pandemic.“

Pandemic grief in El Salvador: factors that predict dysfunctional grief due to a COVID-19 death among Salvadoran adults
(Springer Science and Business Media Deutschland GmbH, 2023-03-29) Lobos-Rivera, Marlon Elías; Flores-Monterrosa , Angélica Nohemy; Tejada-Rodríguez, Jennifer Carolina; Chacón-Andrade, Edgardo René; Caycho-Rodríguez, Tomás; A Lee, Sherman; D Valencia, Pablo; Carbajal-León, Carlos; W Vilca, Lindsey; Reyes-Bossio, Mario; Gallegos , Miguel
Thousands of people have died of COVID-19 in El Salvador. However, little is known about the mental health of those who are mourning the loss of a loved one to COVID-19. Therefore, the objective of this study was to examine the dysfunctional grief associated with COVID-19 death among Salvadoran adults. A sample of 435 Salvadorans (M = 29 years; SD = 8.75) who lost a family member or loved one to COVID-19 completed a digital survey using the Google Forms platform, during April 2 and 28, 2022. The results revealed that 35.1% reported clinically elevated symptoms of dysfunctional grief and among those mourners, and 25.1% also exhibited clinical levels of coronavirus anxiety. A binary logistic regression revealed that predictor variables such as COVID-19 anxiety (p = .003), depression (p = .021), and COVID-19 obsession (p = .032) were significant (χ2 = 84.31; Nagelkerke R2 = .242) and predict a 24.2% chance of dysfunctional bereavement.

Psychometric evidence of a new short version in Spanish of the COVID-19 impact scale: A study based on confirmatory factor analysis, graded response model, multigroup analysis, and path analysis
(MODESTUM LTD, 2022-08-20) Caycho-Rodríguez , Tomás; Vilca, Lindsey W.; Carbajal-León, Carlos; Reyes-Bossio, Mario; Delgado-Campusano, Mariel; Gallegos, Miguel; Carranza Esteban, Renzo; vNoe-Grijalva, Martin
“The aim of the study was to translate and evaluate the psychometric evidence of the Spanish version of the COVID19 impact scale in the general population of Peru, to measure psychological stress responses produced by the COVID-19 pandemic, including emotional responses and difficulty in performing activities of daily living. Participants were 601 Peruvians, who responded to an online survey consisting of questions designed to collect sociodemographic data, the CIS and the fear of COVID-19 scale. The forward and backward translation method was used to translate the English version into Spanish. A confirmatory factor analysis (CFA), graded response model was used to estimate the discrimination (a) and difficulty (b) parameters of the items. Multi-group CFA was used to assess measurement invariance. Regarding validity based on the validity in relation to other variables, an explanatory model was proposed using the SEM path method. The unidimensional structure of the 10-item CIS was not confirmed. Therefore, it was suggested that a six-item model of the CIS (CIS-6) provides a better fit and reliable score. The multigroup CFA showed that the CIS-6 does not exhibit measurement invariance between males and females. In addition, the CIS-6 items present adequate discrimination and difficulty indices. A higher presence of the latent trait (in this case, perception of the impact of COVID-19) is required to answer the higher response categories. The findings would help to assess those individuals more prone to the impact of the COVID19 pandemic and to have evidence for the development of interventions aimed at decreasing the impact.“

What Is the Support for Conspiracy Beliefs About COVID-19 Vaccines in Latin America? A Prospective Exploratory Study in 13 Countries
(Frontiers Media S.A., 2022-05-06) Caycho-Rodríguez, Tomás; Ventura-León, José; Valencia, Pablo D.; Vilca, Lindsey W.; Carbajal-León, Carlos; Reyes-Bossio, Mario; Gallegos, Miguel; Cervigni, Mauricio; Martino, Pablo; Palacios, Diego Alejandro; Moreta-Herrera, Rodrigo; Samaniego-Pinho, Antonio; Lobos Rivera, Marlon Elías; Puerta-Cortés, Diana Ximena; Corrales-Reyes, Ibraín Enrique; Calderón, Raymundo; Pinto Tapia, Bismarck; Arias Gallego, Walter L.; Petzold, Olimpia
Conspiracy theories about COVID-19 began to emerge immediately after the first news about the disease and threaten to prolong the negative impact of the COVID-19 pandemic by limiting people’s willingness of receiving a life-saving vaccine. In this context, this study aimed to explore the variation of conspiracy beliefs regarding COVID-19 and the vaccine against it in 5779 people living in 13 Latin American countries (Argentina, Bolivia, Chile, Colombia, Cuba, Ecuador, El Salvador, Guatemala, Mexico, Paraguay, Peru, Uruguay and Venezuela) according to sociodemographic variables such as gender, age, educational level and source of information about COVID-19. The study was conducted during the COVID-19 pandemic between September 15 and October 25, 2021. The Spanish-language COVID-19 Vaccine Conspiracy Beliefs Scale (ECCV-COVID) and a sociodemographic survey were used. The results indicate that, in most countries, women, people with a lower educational level and those who receive information about the vaccine and COVID-19 from family/friends are more supportive of conspiracy ideas regarding the COVID-19 vaccine. In the case of age, the results vary by country. The analysis of the responses to each of the questions of the ECCV-COVID reveals that, in general, the countries evaluated are mostly in some degree of disagreement or indecision regarding conspiratorial beliefs about COVID-19 vaccines. The findings could help open further study which could support prevention and treatment efforts during the COVID-19 pandemic.
