(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.

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.“

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.“
