Assessment of Obsessive Thoughts About COVID-19 in 7 Latin American Countries: Structure and Measurement Invariance of the Obsession With COVID-19 Scale.

The present study aimed to evaluate the measurement invariance of the Obsession with COVID-19 Scale (OCS) among seven Latin American countries: Bolivia, Brazil, Cuba, El Salvador, Guatemala, Paraguay, and Uruguay. Although the OCS has been used in several countries and languages, there is a need for approaches that better integrate the cross-cultural equivalence of the scale. A total of 3185 people participated in the study. The results indicated the presence of a unidimensional structure and good reliability indices for the OCS in each country. The alignment method indicated that the OCS is an invariant measure of COVID-19 obsession among the populations of seven Latin American countries. The findings based on IRT analysis indicated that all OCS items had adequate discrimination and difficulty parameters. The findings contribute to the understanding of the internal structure of the scale in different countries at the same time, something that has been pending evaluation.

Measurement of Risk Factors Associated With bereavement Severity and Deterioration by COVID-19: A Spanish Validation Study of the Pandemic Grief Risk Factors.

The present study translated and evaluated the psychometric evidence of the Pandemic Grief Risk Factors (PGRF) in a sample of 363 people from the general population of Peru who suffered the death of a loved one by COVID-19 (63-4% women and 36.6% men, where 78.5% were between 18 and 29 years old). The findings indicated that the PGRF is a unidimensional and reliable measure. The PGRF items can differentiate between individuals with different levels of risk factors and thus cover a wide range of the latent construct. Also, a greater sense of distress for each of the risk factors for pandemic grief is necessary to answer the higher response categories. Risk factors significantly and positively predict COVID-19-associated dysfunctional grief. The results indicated that the PGRF in Spanish is a measure with adequate psychometric properties to measure risk factors for pandemic grief.

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.

Intention to receive the monkeypox vaccine and its psychological and sociodemographic predictors: a cross-sectional survey in the general population of Peru.

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.

Spanish Translation and Validation of the COVID Stress Scales in Peru.

The objective of the study was to translate and validate the COVID Stress Scales (CSS-36) into Spanish in Peru. Around 1,424 people, selected through a non-probabilistic sampling, participated in the study. Factor analysis confirmed an initial six-dimensional factorial structure of the CSS-36. Reliability by internal consistency was good for the dimensions of fear of danger, socioeconomic consequences, xenophobia, fear of contamination, traumatic stress, and compulsive control. In addition, the factorial structure of scale has been shown be strictly invariant for both males and females. The Spanish version of the CSS-36 has evidence of validity, reliability, and invariance to measure COVID-19 stress in a Peruvian sample.

The Monkeypox Fear Scale: development and initial validation in a Peruvian sample.

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.

Single item to assess for worry for cancer: Initial evidence of validity and reliability.

OBJECTIVE: To translate into Spanish and evaluate the evidence of content validity, construct validity and reliability of the Cancer Worry Chart as a single item measure of worry for cancer. METHOD: The Spanish translation of the Cancer Worry Chart was done with the back-translation procedure. The participants were 165 healthy people with a family history of cancer who responded to the Cancer Worry Chart and the Cancer Worry Scale (CWS). RESULTS: Translation back-translation allows a Spanish version of the Cancer Worry Chart whose content is clear, coherent and relevant (V>.70). Evidence of construct validity is reported based on 3 criteria: (a) an adequate adjustment of the one-dimensional model formed by the Cancer Worry Chart and the items of the CWS performed with the structural equations method (χ2S-B=23.38; df=14; χ2S-B/df=1.67; CFI=.988; RMSEA=.064); (b) a significant correlation between the Cancer Worry Chart and the CWS (r=.76 [IC95%: .68-.90]); (c) ascending averages in the CWS score as the groups formed by each response option of the Cancer Worry Chart express a greater degree of worry (F=55.72; p=.000; ω2=.57). The reliability of the Cancer Worry Chart is above what is recommended (αsingle item=.84). CONCLUSION: The Spanish version of the Cancer Worry Chart showed satisfactory evidence of content validity, construct validity and reliability to measure, briefly, quickly and generally, the worry for cancer in healthy people with a family history of cancer.
