Students in engineering tend to be loners, making interpersonal relationships and mental health issues more likely to arise. The COVID pandemic caused university students to experience anxi-ety and depression, which affected their academic performance and self-esteem. However, stu-dents’ mental health was rarely evaluated after the pandemic, especially engineering students, who showed higher levels of depression than students from other disciplines. The present study aims to establish an explanatory model of academic self-efficacy based on factors related to mental health, such as anxiety, depression, and negative emotions. The method used was quan-titative cross-sectional, and a structural equation modeling was used. A sample of 561 students (54.4% males and 45.6% females) was analyzed. Instruments to measure self-efficacy, negative affect, depression, and anxiety, previously validate...

Studying grit's measurement helps to understand this psychological phenomenon associated with success. Grit-S structures of one-factor and two-factor have been reported in the literature, but there is a lack of reports based on Item Response Theory (IRT). Therefore, two objectives were proposed: to determine the factorial structure of the Spanish version of the Grit-S and explore the instrument through a Multidimentional Item Response Theory (MIRT) analysis. A nonprobabilistic sample of 899 subjects (41.0% female) was evaluated. The 8 items grit scale was used. The Confirmatory Factor Analysis (CFA) showed that the two-factor model obtained a good fit (CFI = 0.97, TLI = 0.95, RMSEA [90%CI] = 0.08 [0.07, 0.10]) unlike the one-dimensional model. An exploratory comparison analysis by MIRT also revealed that the two-factor model performed better (p < 0.001). Consequently, a confirmatory anal...

Existe una imperiosa necesidad de evaluar los instrumentos de procrastinación actuales, con especial atención a la Escala de Procrastinación Académica (EPA), ampliamente utilizada en Latinoamérica, cuya dimensionalidad ha experimentado variaciones constantes en la literatura. Para ello se aplicó la EPA a 1308 estudiantes universitarios siguiendo un muestreo no probabilístico. Inicialmente, se observó que el ítem 4 reflejaba una actividad cotidiana más que comportamientos directos de procrastinación. Posteriormente, se exploraron diversas variaciones de la EPA, conforme a la literatura y las propuestas del presente estudio. El modelo de dos factores, excluyendo el ítem 4 y con correlación de errores entre los ítems 6 y 7, demostró ser adecuado en términos de ajuste, logrando la invarianza entre los participantes de ambos sexos. El estudio concluye que se debe emplear la EP...

Introducción: La autoeficacia y el eutrés son elementos motivacionales que guían al éxito académico; mientras que la procrastinación guía al fracaso. Está comprobado que la autoeficacia y eutrés afectan a las conductas de procrastinación, pero ¿en qué medida? Además, en la literatura se evidencian diferencias entre el género en relación con estas variables. No obstante, estos estudios no son concluyentes. Por ello, esta investigación tuvo por objetivo establecer un modelo explicativo e invariante del efecto de la autoeficacia hacia las conductas de procrastinación, mediado por el eutrés. Metodología: Se utilizó el diseño de regresiones estructurales con variables latentes, y se aplicó invarianza multigrupo. La muestra fue no probabilística de 1224 universitarios (61.5% mujeres) entre 18 a 35 años (M = 22.89; DE = 5.46). Resultados: Se hallaron adecuados índices d...

Introduction: In Peru, a high proportion of fully immunized people against COVID-19 has been achieved, which has mitigated the severity of the disease. Thus, under the recommendation of experts, the Peruvian government issued Supreme Decree 118-2022-PCM, which indicated that the use of masks is optional in open and ventilated enclosed spaces as of October 1, 2022. Objective: The aim of the present study was to find out the reasons why people continued to wear masks even though it was not mandatory in outdoor environments. Methods: A total of 335 people participated, with an average age of 26.11 years (73.1% women). A data collection form was prepared where sociodemographic and health information was requested; in addition, the question "Why do you continue to wear mask despite it being optional in open and closed ventilated spaces?" was included. The data obtained from the last open ques...

Introduction: Worldwide, anxiety and depression are the most common mental disorders, both in clinical settings and in the general population. The Patient Health Questionnaire-4 is the most widely used open access instrument to assess anxiety and depression in both clinical and community settings. Objective: The study aims to evaluate the psychometric evidence of the Patient Health Questionnaire (PHQ-4). Method: 1015 Peruvian individuals between 18 and 69 years old (M=26.4, SD=9.93, 58.6% women) who experienced the death of a loved one participated. Techniques derived from Classical Test Theory and Item Response Theory (IRT) were used. Results: Three models were tested: one-dimensional (CFI = 0.989; TLI = 0.966; RMSEA = 0.075), the two-factor model (CFI = 1.000; TLI = 1.000; RMSEA = 0.000) and the bifactor model which did not converge. The two-factor model was the one that came closest t...

This study aimed to evaluate the psychometric properties of the Grief Impairment Scale (GIS) using a network psychometric model. A total of 1048 individuals from Peru and El Salvador participated. A network psychometric model was used to determine internal structure, reliability, and cross-country invariance. The results indicate that the GIS items were grouped into a single network structure through Exploratory Graph Analysis. Reliability was estimated by structural consistency, and it was found that when replicating the network structure within an empirical dimension, a single network structure was consistently obtained, and all items remained stable. Furthermore, the network structure was invariant, thus functioning similarly across the different country groups. In conclusion, the GIS presented solid psychometric evidence of validity based on its internal structure, reliability, and c...

The Grief Impairment Scale (GIS) is used to measure functional impairment due to grief following the death of a loved one. However, there is no information on its cross-cultural utility. Thus, this study assessed the measurement invariance of the GIS using a large sample of bereaved adults (N = 2060) from Peru, El Salvador, Ecuador, and Colombia. Specifically, we employed two measurement invariance techniques: multi-group confirmatory factor analysis (MG-CFA) and the alignment optimization method. The results indicated that the GIS demonstrated configural and metric invariance, but not scalar invariance through MG-CFA. The alignment optimization method indicated the presence of an approximate invariance. Therefore, the results suggest that the GIS measures grief-related impairment similarly across the four Latin American countries. Among the countries examined, Peru reported the highest ...

Objectives: The present study aimed to evaluate the measurement invariance of a general measure of the perception of governmental responses to COVID-|19 (COVID-SCORE-10) in the general population of 13 Latin American countries. Methods: A total of 5780 individuals from 13 Latin American and Caribbean countries selected by non-probabilistic snowball sampling participated. A confirmatory factor analysis was performed and the alignment method was used to evaluate invariance. Additionally, a graded response model was used for the assessment of item characteristics. Results: The results indicate that there is approximate measurement invariance of the COVID-SCORE-10 among the participating countries. Furthermore, IRT results suggest that the COVID-SCORE-10 measures with good psychometric ability a broad spectrum of the construct assessed, especially around average levels. Comparison of COVID-S...

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 scal...

This study aimed to characterize the network structure of pandemic grief symptoms and suicidal ideation in 2174 people from eight Latin American countries. Pandemic grief and suicidal ideation were measured using the Pandemic Grief Scale and a single item, respectively. Network analysis provides an in-depth characterization of symptom-symptom interactions within mental disorders. The results indicated that, “desire to die,” “apathy” and “absence of sense of life” are the most central symptoms in a pandemic grief symptom network; therefore, these symptoms could be focal elements for preventive and treatment efforts. Suicidal ideation, the wish to die, and the absence of meaning in life had the strongest relationship. In general, the network structure did not differ among the participating countries. It identifies specific symptoms within the network that may increase the likel...

The present study aimed to apply a network analysis model to provide an exploratory empirical conceptualization of dynamic networks of posttraumatic growth (PTG) symptoms in 7,434 people who experienced the death of a loved one from COVID-19 in 16 Latin American countries. The Post-Traumatic Growth Inventory: Short Form of Eight Items was used. A non-regularized network with partial correlation coefficients was estimated through the ggmModSelect algorithm. The network architecture was analyzed for each country through its local properties and global properties. The results indicated that the networks differed significantly between countries. The core dimensions in the networks were relating to others, personal strength, and life value and opportunities, which were more related dimensions that reinforce the emergence of PTG in all countries. The findings may be useful to motivate research...

The present study explored the predictive capacity of fear of COVID-19 on the intention to be vaccinated against COVID-19 and the influence in this relationship of conspiracy beliefs as a possible mediating psychological variable, in 13 Latin American countries. A total of 5779 people recruited through non-probabilistic convenience sampling participated. To collect information, we used the Fear of COVID-19 Scale, Vaccine conspiracy beliefs Scale-COVID-19 and a single item of intention to vaccinate. A full a priori Structural Equation Model was used; whereas, cross-country invariance was performed from increasingly restricted structural models. The results indicated that, fear of COVID-19 positively predicts intention to vaccinate and the presence of conspiracy beliefs about COVID-19 vaccines. The latter negatively predicted intention to vaccinate against COVID-19. Besides, conspiracy bel...
