"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"
"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.

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
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

The Monkeypox Fear Scale: development and initial validation in a Peruvian sample
Abstract Background Fear is one of the basic emotions generated during periods of infectious diseases. Therefore, the aim of this study was to develop and validate a scale that assesses monkeypox fear, the Monkeypox Fear Scale (MFS). Methods A total of 451 Peruvians participated (61% women and 39% men), with a mean age of 28.31 years (SD = 9.72). based on procedures from classical test theory (CTT) and item response theory (IRT). Classical Test Theory (CTT) and Item Response Theory (IRT) procedures were used. Results The results showed that MFS has a two-factor structure related to emotional and physiological fear factors (χ2 = 41.87; df = 12; p < .001; CFI = .99; TLI = .99; RMSEA = .074 [IC90% .051–.100]). In addition, the physiological and emotional factors showed good reliability. Measurement invariance analysis showed that the factor structure of the MFS is strictly invariant between male and female groups. Finally, the discrimination and difficulty parameters of the items show adequacy. In addition, the scale seems to be more accurate in measuring high levels of fear of monkeypox. Conclusion The MFS has adequate psychometric evidence to assess fear of monkeypox in the Peruvian population. These findings may guide future studies related to the consequences of monkeypox on mental health
Measuring God Mysticism: New Results of the Short Version of the God Mysticism Scale
The brief God Mysticism Scale (GMS-B) is a 12-item scale that assesses the perception of God mysticism. The study aimed to evaluate the psychometric properties of the Spanish version of the GMS-B. The sample consisted of 421 young Peruvians from the city of Lima with a mean age of 26.76 years, recruited by convenience sampling using a snowball method. Construct validity, internal consistency reliability, difficulty and discrimination indices of the items, and measurement invariance across sex of the GMS-B were evaluated using procedures derived from classical test theory and item response theory. A confirmatory factor analysis suggested that the original model of two correlated factors did not show adequate fit indices. For this reason, after testing a set of factorial models, it was determined that a brief model of five items written in a positive manner (GMS-5) presented the best fit. In addition, the GMS-5 presented adequate reliability indices (α = 0.94; ω = 0.94), all the items presented adequate discrimination indices, and the difficulty parameters increased monotonically. Therefore, a higher level of the perception of God mysticism is necessary to answer the higher answer options on the scale (for example, respond to option 9 = Definitely true from my experience). Finally, the GMS-5 showed evidence of being strictly invariant for the groups of men and women. In conclusion, the GMS-5 is a unidimensional, reliable, and invariant instrument to assess mysticism among young men and women in Peru
Intention to receive the monkeypox vaccine and its psychological and sociodemographic predictors: a cross-sectional survey in the general population of Peru
Abstract Objective The objective of this study was to identify predictors of intention to be vaccinated against Monkeypox (Mpox) in a sample of Peruvian citizens. Methods A set of sociodemographic and psychological predictors were used, such as sex, sexual orientation, educational level, previous diagnosis of COVID-19, marital status, complete vaccination against COVID-19, employment status, living with vulnerable people, presence of chronic disease, area of residence, perceived usefulness of COVID-19 vaccines, fear of Mpox, conspiracy beliefs about Mpox, among others. A total of 472 Peruvian adults participated, selected by non-probabilistic snowball convenience sampling. A sociodemographic survey, the Mpox Fear Scale, was used. Conspiracy Beliefs about Mpox was assessed using three questions created specifically for this study. For inferential purposes, simple ordinal regressions ("crude models") were performed between each factor and the outcome. Results Regarding their intention to be vaccinated against Mpox, more than 60% expressed clear approval. Being non-heterosexual, having greater emotional fear of Mpox, and perceiving some potential for this disease to become the next pandemic were related to greater intention to vaccinate. On the other hand, being older, having low perceived usefulness of COVID-19 vaccines, and having higher conspiracy beliefs about Mpox were associated with lower intention to vaccinate. Conclusion The study provides initial information for future research seeking to better analyze Mpox vaccination intention. In addition, cross-sectional data are provided that can be used to develop public health policies that target subgroups with low prevalence of intention to vaccinate against Mpox
