    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 cross-cultural 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.

    Loneliness is a public health problem. Its assessment is important to identify older adults who experience greater loneliness and appropriate interventions can be carried out. The De Jong Gierveld Solitude Scale (DJGLS) is one of the most widely used, at least in the European context, to measure loneliness. Although the Spanish version of the DJGLS has shown reliability and validity in Spanish samples of older adults, there is no evidence of adequacy in the Latin American context. Therefore, this study aims to evaluate the psychometric properties of the DJGLS in Peruvian older adults. Specifically, factorial validity, internal consistency and criterion-related validity were studied, based on a double analytical perspective: Classical Test Theory (SEM models) and Item Response Theory. The participants were 235 Peruvian older adults with ages ranging from 61 to 91 years old (Mean = 72.69, SD = 6.68) that assisted to Centers for the Elderly in the city of Trujillo, Peru. Together with the DJGLS, information from the three-item UCLA loneliness scale, Satisfaction with Life Scale, Brief Resilient Coping Scale and the Patient Health Questionnarie-2 was also gathered. The results support a one-dimensional structure of the DJGLS but with the presence of method effects associated to the negatively worded items. Additionally, the IRT multidimensional model applied also indicated the presence of a second dimension related to these negative items. Finally, other evidences of reliability and validity were adequate. In summary, the DJGLS may be considered a reliable and valid instrument to be used in the Peruvian (older adults) context.

    Introduccion: La COVID-19 ha generado repercusiones en la forma de practicar la religion, ante ello, un grupo de creyentes demuestra ideas fatalistas en relacion al origen y consecuencias del nuevo coronavirus. Objetivo: Adaptar la Religious Health Fatalism Measure for the African-American Faith Community para el contexto de la COVID-19 en poblacion peruana. Metodos: Estudio instrumental, donde participaron voluntariamente 764 adultos (59,03% mujeres y 40,97% varones) de la costa, sierra y selva peruana. Los items de la Religious Health Fatalism Measure fueron adaptados culturalmente mediante un proceso de cinco pasos: traduccion directa, sintesis de traducciones, traduccion inversa, consolidacion del comite de expertos y prueba piloto. El analisis de datos implico calcular estadisticos descriptivos, ejecutar un Analisis Factorial Confirmatorio y para analizar la bondad de ajuste del modelo original, se utilizo el modelamiento de ecuaciones estructurales. Resultados: Los items de la escala de fatalismo religioso ante la COVID-19 muestran evaluaciones favorables acerca de su claridad, representatividad y relevancia, donde todos los valores V de Aiken fueron estadisticamente significativos y mayores a 0,70. A traves del Analisis Factorial Confirmatorio se evidencio un modelo con nueve items distribuidos en dos factores (RMR = 0,036, GFI = 0,980, AGFI = 0,952, NFI = 0,981, RFI = 0,969, IFI = 0,983, TLI =0,971, CFI = 0,983, RMSEA = 0,079), ademas, la confiabilidad fue aceptable (α > 0,78, IC 95% > 0,78 – 0,81). Conclusiones: La version modificada FAT-RCov19 demuestra evidencias de validez y confiabilidad para medir el fatalismo religioso ante la COVID-19 en adultos peruana.

    Participants A total of 203 patients with type 2 diabetes mellitus who attended nine primary care areas in four Cuban provinces belonging to different regions of the country (Pinar del Río, La Habana, Ciego de Ávila and Santiago de Cuba) participated in the study. Participants were selected by non-probabilistic sampling based on the following inclusion criteria: 1. have a diagnosis of type 2 DM according to the World Health Organization criteria, 2. be older than 18 years old, 3. be patients of the health care areas mentioned above, and 4. be willing to participate in the study and to sign the informed consent form. Patients with mental illness, cognitive deficit (dementia, psychosis or mental disability) or other apparent condition that prevents understanding and completion of the questionnaire were excluded. Although retrospective data on infection rates in diabetic patients suggest that people with type 1 DM are at higher risk for infectious diseases in general, and death rates are similar to those of people with type 2 DM,this study focused on the latterfortwo main reasons. First, patients with type 1 DM are mostly children and young people and the prevalence of this type of diabetes is lower compared to type 2 DM, which leads to a lower number of patients seen in consultation and primary health care. Second, the study was conducted in the context of the COVID-19 pandemic and patients with type 2 DM were the most accessible population to be surveyed by the research team in primary care areas. The minimum sample size was calculated with the Soper software package for a multiple regression study, according to the desired probability level (α=0.05), the number of predictors in the model (18 predictors), the anticipated effect size (f2=0.15) and the desired statistical power level (1- β=0.80). The software suggested a minimum number of 118 participants; however, the final number was higher than the minimum required. Instruments Socio-demographic and health information A questionnaire was developed specifically for this study, where participants were asked to provide information about their sex, age, educational level, type of work, cohabitation, marital status, presence of chronic complications, presence of comorbidities, family or friends infected with COVID-19, and time since diagnosis with DM. Concern about COVID-19 contagion We used the COVID-19 contagion concern scale (PRECOVID-19) originally developed for the general population, which assesses worry about becoming infected with COVID-19 and its impact on people’s mood and ability to perform daily activities. In this study we used the version validated for Cuban patients with diabetes, which consists of 5 items. All items have 4 Likert-type response options, ranging from 1=never or rarely to 4=almost all the time. The PRE-COVID-19 has a unidimensional structure, where the total score is calculated by adding the scores of each of the 5 items. Higher scores indicate greater concern about becoming infected with COVID19. The reliability of the PRE-COVID-19 for this study was very good (ω=0.91). Blood glucose level Fasting blood glucose values were obtained from the patients’ clinical histories and from blood tests performed in the last three months in laboratories equipped for this purpose. Based on this, poor glycemic control was determined as fasting blood glucose greaterthan or equal to 7 mmol/L (126 mg/dl) in the last three months and good control as figures below this value. The criterion based on glycosylated hemoglobin (HbA1c) could not be used because it is not a test regularly available in the primary health care system where the survey was applied. Other control criteria using continuous glucose monitoring systems were not possible either, as they are not generally available for patients with DM living in Cuba. Procedure The questionnaire was applied by properly trained researchers, who complied with strict COVID-19 prevention health protocols, between the months of January and April 2021. The questionnaire was administered during patients’ visits to primary care centers or in their homes. During this period of time, the fight against COVID-19 in Cuba suffered some setbacks, characterized by an increase in the number of infected people, even higherthan that observed during the first stage of the disease, in 2020. Thus, during those dates, more than 64,414 positive diagnoses and 384 deaths were reported in the country. Participation was voluntary and without any financial compensation. Participants signed the informed consent form and were informed that they could withdraw from the study at any time. Similarly, the reliability of the data was guaranteed. The study protocol was approved by the Ethics Committee of theUniversidad Privada delNorte in Peru (registration number: 20213002). Data Analysis The frequencies and percentages of the categorical variables included in the model were examined. In the case of the outcome variable (concern about COVID-19 contagion), the mean±standard deviation (SD) was calculated for the total sample. These values were then also calculated for each category of each variable. For inferential purposes, bivariate associations were examined with a series of analyses of variance (ANOVA). The assumption of homoscedasticity was reasonably well met in most cases; however, a possible noncompliance with the assumption of normality of the residuals was observed. Therefore, we repeated the analyses after a power transformation of the outcome variable. Since the results were practically identical with both procedures, only those obtained with the variable in its original form are reported. Variables that reached statistical significance (p<.05) in the ANOVAs were selected as potential predictors in a linear regression. Crude (simple) regressions were run, which replicated the ANOVAs but also allowed for a more detailed examination of between-group differences. Finally, a fitted (multiple) regression was run with all predictors simultaneously. Statistical significance was judged from the 95% CIs, which provide a set of possible values of the coefficient in the population. A CI that does not include zero is equivalent to a p<.05.

    The aim of this study was to evaluate the psychometric evidence of the original and brief version of the Santa Clara Strength of Religious Faith Questionnaire (SCSRFQ) in Spanish in a sample of 245 Peruvian adolescents and adults (mean age = 21.04 years, SD = 3.07, 47.8% male and 52.2% female), selected by non-probabilistic convenience sampling. Additionally, the Coronavirus Anxiety Scale and the Satisfaction with Life Scale were applied. Confirmatory Factor Analysis, internal consistency reliability methods, hierarchical sequence of variance models and Graded Response Model were used. Results indicate that both versions of the SCSRFQ showed robust psychometric properties: adequate unidimensional structure, adequate difficulty and discrimination parameters, and significant relationships with the measures of fear of COVID-19 and satisfaction with life. The original version of the SCSRFQ showed evidence of strict measurement invariance by gender and age; whereas the short version showed strict invariance by gender and configural invariance by age. Both versions showed acceptable reliability indices. In conclusion, the original and brief versions of the SCSRFQ show evidence of psychometric indicators that support their use to assess the strength of religious faith

    "Introducción: el cuestionario Feedback in Medical Education (FEEDME-Provider) es un instrumento que mide la interacción entre el estudiante o residente de medicina con el médico que le brinda el feedback.Objetivos: el objetivo de este trabajo es traducir, adaptar culturalmente el cuestionario FEEDME-Provider al español latinoamericano, evaluar su consistencia interna y la validez de contenido y del constructo estructural.Métodos: se realizó un estudio analítico observacional de tipo instrumental en 139 estudiantes de medicina. La validez de la escala se determinó mediante el coeficiente V de Aiken y sus intervalos de confianza del 95 %. Además, se realizaron pruebas de análisis factorial y confiabilidad.Resultados: todos los valores del coeficiente V de Aiken fueron estadísticamente significativos (V > 0,70) con valores del límite inferior del IC 95 % apropiados. La asimetría y curtosis de los ítems fueron inferiores a ± 1,5. En el análisis factorial exploratorio se evidenció la existencia de 3 factores, los cuales corresponden con la estructura teórica de la escala original. Todos estos presentaron valores de saturación > 0,30. Sin embargo, el 1 el 3 se eliminaron por no corresponder teóricamente con su factor. Respecto a la confiabilidad de la escala total y sus factores, el coeficiente α de Cronbach es superior a 0,80, que indica que una escala presenta consistencia interna. Conclusiones: la adecuada traducción y adaptación cultural del contenido de los ítems produjo consistentes propiedades psicométricas (confiabilidad, validez de contenido y de constructo estructural) de las puntuaciones de la Escala de FEEDME-Proveedor en una muestra de estudiantes peruanos de medicina humana."

    BACKGROUND: Moral injury is prevalent among health care professionals, especially nurses. It can have negative personal consequences for clinicians, and indirectly impact the quality of patient care. Although nurses around the world experienced moral injury during the pandemic, it will continue to be a professional challenge. Thus, this study aimed to determine the psychometric properties of a scale measuring moral injury translated into Spanish. METHODS: A methodological study with a cross-sectional approach was conducted. After translating the Moral Injury Symptom Scale for Healthcare Professionals (MISS-HP) into Peruvian Spanish (MISS-HP-S) using International Test Commission methods, data were collected using online survey methods from a sample of 720 Peruvian nurses. Analytical methods included exploratory and confirmatory factor analysis, and invariance by age were examined. The corrected homogeneity index, ordinal alpha, and McDonald's omega allowed the evaluation of internal reliability. RESULTS: Findings from this sample of nurses who were mostly female (92%), from coastal Peru (57%), and averaged 39 (± 11) years of age, provided support for the validity and reliability of the MISS-HP-S. Structural validity was endorsed by findings indicating consistent factorial structure and adequate invariance among different age groups. In this study, three factors were observed: guilt/shame, condemnation, and spiritual strength. Internal consistency values included an ordinal alpha of 0.795 and McDonald's omega of 0.835. CONCLUSION: These findings differ from those reported from previous studies in other cultural contexts, suggesting the influence of cultural and sample-specific factors in the perception of moral injury among Peruvian nurses. Because this evidence supports the validity of the MISS-HP-S, it can be used in professional practice and in future research to identify and address situations that contribute to nurse moral injury.

    Resumen: El programa del perdón REACH es un tratamiento viable y basado en evidencias, sin embargo, no ha sido aplicado en participantes hispanohablantes. Por lo tanto, el objetivo del estudio fue determinar la efectividad del programa del perdón REACH sobre la depresión, la ansiedad, el estrés y las motivaciones ante la transgresión interpersonal en universitarios residentes en la selva peruana. El diseño fue experimental, de tipo cuasi-experimental. Participaron 38 universitarios (71.1% mujeres) con edades de 18 a 40 años (M=21, Me= 20,50, DE=4,29), divididos en dos grupos (grupo de intervención, 20; y control, 18). Se utilizó la Escala de Depresión, Ansiedad y Estrés (DASS-21), la escala Transgression-Related Interpersonal Motivations (TRIM-18) y el programa del perdón REACH de Worthington. Los resultados evidenciaron que, en el grupo de tratamiento, se redujeron los síntomas de depresión, ansiedad y estrés. Además de incrementarse el perdón y disminuir la venganza y la evitación hacia el ofensor; no obstante, no hubo diferencias significativas en benevolencia. Mientras que, en el grupo control, no se encontraron diferencias significativas antes y después del tratamiento. Se concluye que el programa del perdón es efectivo para mejorar la salud mental y las relaciones interpersonales de los universitarios participantes.
