Most studies only describe mental health indicators (anxiety, depression, insomnia, and stress) and the risk factors associated with these indicators during the pandemic (sex, student status, and specific physical symptoms). However, no explanatory studies have been found that assess the impact of variables associated with COVID-19. Against this background, the objective of the study was to evaluate the impact of the fear of catching COVID-19 on the level of anxiety, depression, and insomnia in 947 university students of both sexes (41.6% males and 58.4% females) between the ages of 18 and 35 (M = 21.6; SD = 3.4). The Fear of catching COVID-19 Scale, the Generalized Anxiety Disorder Scale (GAD-7), the Patient Health Questionnaire (PHQ-9), and the Insomnia Severity Index (ISI) were used to measure the variables. The results of the study show that the fear of catching COVID-19 significantl...

“Currently, social anomie is a public health problem worldwide since people show behavior that does not conform to the newly established norms. Faced with this, the aim of the study was to develop and validate the psychometric properties of a short scale to assess social anomie in a sample of 406 adults (48% male and 52% female) between the ages of 18 and 62. Validity was evaluated based on internal structure through confirmatory factor analysis (CFA) and reliability through the internal consistency method with the hierarchical omega coefficient. The results indicate that a bi-factor model presents better indexes of adjustment to the data (χ2=62.86; df=25; p=.000; RMSEA=.061 [IC90% .042-.080]; SRMR=.024; CFI=.99; TLI=.99). Furthermore, the bi-factor model presents adequate levels of reliability for the general factor (ωH=.70) and for the affective (ωhs=.32) and behavior (ωhs=.41) d...

ABSTRACT The aim of this study was to assess the factorial structure of the scale, the method's effect associated with its negative items, its temporal invariance, and factorial invariance according to sex. For this purpose, three samples were collected, an initial sample of 200 participants, a second sample of 461 participants and a third sample of 107 participants; making a total of 768 Peruvian university students. Other instruments were applied together with the EROS scale in order to measure satisfaction with life, anxiety, stress and depression. Regarding the results, in the initial sample it was found that the original scale containing positive and negative items does adequately fit the data (RMSEA = .19; CFI = .77; TLI = .71) and also evidence was found supporting the existence of a methodological effect associated with the negative items. It was also found that versi...

Background and objective The Coronavirus Anxiety Scale (CAS) is an instrument that measures the severity of anxiety due to COVID-19 or coronaphobia.

ABSTRACT This study evaluated the psychometric properties of the Pandemic Grief Scale (PGS), using Classical Test Theory (CTT) and Item Response Theory (IRT) methods, in a sample of 458 people who have suffered the loss of a loved one due to the COVID-19 pandemic. The Pandemic Grief Scale, Patient Health Questionnaire-2 (PHQ-2), the two-item Generalized Anxiety Disorder Scale (GAD-2), and a single item on suicidal ideation were used. The unidimensional model had good fit and reliability; furthermore, convergent validity was demonstrated based on the relationships between dysfunctional grief, anxiety symptoms, depression, and suicidal ideation. Additionally, a higher presence of dysfunctional grief is required to answer using the higher response categories. The evidence of validity and reliability of the PGS in its Spanish version, using traditional and modern methods, is confirmed in Per...

ABSTRACT The aim of the study was to analyze the psychometric properties of the Spanish version of the Coronavirus Anxiety Scale (CAS), using Item Response Theory (IRT) and Confirmatory Factor Analysis (CFA). The participants were 790 Peruvians, selected through a convenience sampling, where the majority were women. The CFA models indicated that the one-dimensional structure better represents the data, is reliable and invariant between men and women. Likewise, IRT findings indicate that CAS is more informative for high levels of COVID-19 anxiety. The CAS in Spanish has adequate psychometric properties to be used as a short measure of COVID-19 anxiety.

The aim of this study was to evaluate the psychometric evidence of the original and short versions 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 nonprobabilistic 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 a 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 SCSRF...

Accepted: 19 Oct. 2021 Introduction: In recent years, greater attention has been paid to research on sexual satisfaction because of its association with general well-being and increased interest in sexual and public health issues. Objectives: The objective of this study was to evaluate the psychometric properties of the Satisfaction with Sex Life Scale (SWSLS). Methods: 2,154 Portuguese individuals (M = 34.67 years, SD = 17.18) participated. Confirmatory factor analysis (CFA) and item response theory (IRT) were used. Specifically, the internal structure, reliability and factor invariance of the SWSLS were evaluated by sex and age, as well as the characteristics and performance of the items based on the IRT analysis. Results: The SWSLS Confirmatory Factor Analysis confirmed that a one-dimensional model fit the data well, both for the total sample and for each sex and age group. Furthermor...

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, ...

ABSTRACT Aims It is important to have valid and reliable measures to determine the psychological impact of COVID-19 in patients with diabetes; however, few instruments have been developed and validated for this population. Therefore, the aim of this study was to validate the Scale of Worry for Contagion of COVID-19 (PRE-COVID-19) in a sample of patients with diabetes mellitus (DM). Materials and methods A total of 219 patients (66.2% female, mean age 58.5 SD = 18.2) participated, selected through non-probabilistic sampling. The PRE-COVID-19 and the Generalized Anxiety Disorder Scale-2 were applied. Reliability analysis was performed for internal consistency, structural equation modeling and item response theory modeling. Results The results show that a unidimensional 5-item model presents satisfactory goodness-of-fit indices and excellent reliability values. Likewise, convergent validity...

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 exp...

Introduction: Concern about becoming infected is a particularly relevant psychological aspect in the context of a pandemic, as it is associated with social reactions and behavioral changes. Objectives: The present study sought to determine some sociodemographic and health factors associated with concern about COVID-19 infection in Cuban patients with type 2 diabetes mellitus. Methods: 203 patients with type 2 diabetes mellitus, who attended nine primary care areas of four Cuban provinces belonging to different regions of the country (65.52% female, mean age 57.5, SD=19.2), selected through non-probabilistic sampling, participated in the study. A sociodemographic questionnaire, the COVID-19 contagion concern scale (PRE-COVID-19) and an evaluation of blood glucose level were applied. Bivariate associations were examined with a series of analyses of variance (ANOVA). Adjusted (multiple) reg...

The aim was to test the cross-cultural measurement invariance of the PIL-SF in a sample of people from seven Latin American countries. Additionally, the characteristics of the PIL-SF items were evaluated and to assess the relationship between purpose in life, as measured by the PIL-SF, and fear of COVID-19. A total of 4306 people from seven Latin American countries participated in the study. The results indicated that the PIL-SF is invariant in the seven participating countries and, therefore, there is evidence that the items reflect the purpose of life in the same way in all countries. This allows comparisons of purpose in life between countries that are free of bias, reflecting the true differences in how countries respond to items. From IRT, the discrimination parameters are adequate and indicate that the items cover a wide range of the purpose in life construct. The difficulty parame...
