The implementation of a vaccine against COVID-19 is one of the most important health strategies to mitigate the spread of the disease. The objective of this study was to estimate the prevalence of the intention to be vaccinated against COVID-19 and its predictors in older Peruvian adults. This is a cross-sectional study, where information was collected through an online survey regarding vaccination intention of the participants, as well as sociodemographic and psychological variables. A multiple regression analysis was applied to identify predictors of intention to be vaccinated against COVID-19. We evaluated 245 participants, who had a mean age of 72.74 years old (SD = 6.66). 65.5% of these older adults expressed a high likelihood of accepting vaccination, while 20.9% expressed a low likelihood of accepting vaccination, and 13.6% were hesitant. Eleven predictors were identified that explained 66.69% of the intention to vaccinate against COVID-19. This identified place of residence, perceived likelihood of contracting COVID-19, severity of previous infection with COVID-19, fear of the disease, previous refusal of a vaccine, concerns about vaccine sales and speculation, and trust toward vaccines against COVID-19, as the main predictors. Our results show that confidence in vaccines and previous vaccine refusal are relevant predictors of intention to vaccinate against COVID-19 in older adults; these findings may be useful to guide the development of campaigns for the immunization of this vulnerable group in the current pandemic.

Introducción y Objetivos: El COVID-19 ha generado consecuencias negativas para la salud mental de las personas. Este es el caso del Perú, uno de los países latinoamericanos más afectados por la pandemia. En este sentido, el objetivo del estudio fue traducir y validar la Coronavirus Anxiety Scale (CAS) al español. Material y Método: Los participantes fueron 704 estudiantes universitarios de ciencias de la salud (Medad = 23.39 años, DE = 3.45) a quienes se les administró el CAS en español, el Mental Health Inventory-5 y el Patient Health Questionnaire-2 item. El CAS se tradujo al español mediante el método hacia adelante y hacia atrás. Se examinaron la fiabilidad y las evidencias de validez basada en la estructura interna y relación con otras variables. Resultados: El análisis factorial confirmó la estructura factorial unidimensional del CAS (χ2 = 7.62, gl = 5, p = .18, χ²/df = 1.52, CFI = .99, RMSEA = .03 [90% CI .00, .06]; SRMR = .02, WRMR = .52); además las cargas factoriales fueron grandes y significativas (de .68 a .87). Los cinco ítems del CAS mostraron correlaciones ítems test total corregido aceptables (de .64 a .74). La confiabilidad por consistencia interna fue buena (ω = 0.89; αordinal= 0.89). La evidencia de validez en base a la relación con otras variables del CAS fue respaldada por la correlación positiva con la depresión (r = .52, p <.01) y negativa con el bienestar subjetivo (r = -.50, p <.01). Además, la depresión media la relación entre la ansiedad por el COVID-19 y el bienestar subjetivo (valor bootstrap = - .24, IC 95% = - .28, - .20). Conclusión: La versión en español del CAS posee evidencias de validez y confiabilidad para medir la ansiedad por el COVID-19 en una muestra de universitarios peruanos.

The Coronavirus Anxiety Scale (CAS) was recently developed to assess dysfunctional anxiety related to COVID-19. Although different studies reported that the CAS is psychometrically sound, it is unclear whether it is invariant across countries. Therefore, the present study aimed to examine the measurement invariance of the CAS in twelve Latin American countries (Argentina, Bolivia, Chile, Colombia, Cuba, Ecuador, El Salvador, Guatemala, Mexico, Paraguay, Peru, and Uruguay). A total of 5196 people participated, with a mean age of 34.06 (SD = 26.54). Multigroup confirmatory factor analysis (CFA) was used to examine the measurement invariance of the CAS across countries and gender. Additionally, the graded response model (GRM) was used to provide a global representation of the representativeness of the scale with respect to the COVID-19 dysfunctional anxiety construct. The unidimensional structure of the five-item CAS was not confirmed in all countries. Therefore, it was suggested that a four-item model of the CAS (CAS-4) provides a better fit across the twelve countries and reliable scores. Multigroup CFA showed that the CAS-4 exhibits scalar invariance across all twelve countries and all genders. In addition, the CAS-4 items are more informative at average and high levels of COVID-19 dysfunctional anxiety than at lower levels. According to the results, the CAS-4 is an instrument with strong cross-cultural validity and is suitable for cross-cultural comparisons of COVID-19 dysfunctional anxiety symptoms in the general population of the twelve Latin American countries evaluated.

The invariance of the Preventive COVID-19 Infection Behaviors Scale (PCIBS) was evaluated in 12 Latin American countries (Argentina, Bolivia, Chile, Colombia, Cuba, Ecuador, El Salvador, Guatemala, Mexico, Paraguay, Peru, and Uruguay). A total of 5183 people from the aforementioned countries participated, selected using the snowball sampling method. Measurement invariance was assessed by multigroup confirmatory factor analysis (MG-CFA) and Multi-Group Factor Analysis Alignment (CFA-MIAL). In addition, item characteristics were assessed based on Item Response Theory. The results indicate that the original five-item version of the PCIBS is not adequate; whereas a four-item version of the PCIBS (PCIBS-4) showed a good fit in all countries. Thus, using the MG-CFA method, the PCIBS-4 achieved metric invariance, while the CFA-MIAL method indicated that the PCIBS-4 shows metric and scalar invariance. Likewise, the four items present increasing difficulties and high values in the discrimination parameters. The comparison of means of the PCIBS-4 reported irrelevant differences between countries; however, Mexico and Peru presented the highest frequency of preventive behaviors related to COVID-19. It is concluded that the PCIBS-4 is a unidimensional self-report measure which is reliable and invariant across the twelve participating Latin American countries. It is expected that the findings will be of interest to social and health scientists, as well as those professionals directly involved in public health decision making.
