Psychometric properties of the Escala de Gravedad de Síntomas Revisada del Trastorno de Estrés Postraumático (EGS-R) in adults in Ecuador after the Covid-19 pandemic

2024 , Moreta-Herrera R. , Núñez-Núñez M. , Lascano Arias, Giovanni , Mascialino G. , Rodríguez-Lorenzana A.

Objective: This study aims to assess the validity of the Escala de Gravedad de Síntomas Revisada del Trastorno de Estrés Postraumático (EGS-R) among adults in Ecuador within the post-pandemic context of Covid-19. Methods: Descriptive and instrumental design. Participants: 537 participants from Ambato, Ecuador, comprising 44.1% men and 55.9% women, aged 18 to 65 years (M = 24.36; SD = 8.87). Among the participants, 64.6% had experienced Covid-19, while 35.4% had not. Results: The EGS-R exhibits a hierarchical factorial structure, demonstrating measurement equivalence between participants who experienced Covid-19 and those who did not. Significant differences emerged between the groups, with individuals who had contracted Covid-19 displaying a higher symptom burden, thereby establishing the discriminant validity of the measure. The scale also exhibits validity concerning other variables, such as stress perception, and demonstrates satisfactory internal consistency among its scores. Conclusions: The EGS-R proves to be a valuable tool for assessing adults in Ecuador for potential indicators of Posttraumatic Stress Disorder (PSTD) given the robust evidence of validity and reliability, affirming its utility and evaluative capacity in this population. © 2024

Occupational Risks: A Comparative Study of the Most Common Indicators in Uruguay, Cuba and Ecuador

2023 , Acosta Pérez, Paul Bladimir , Espinosa Pinos, Carlos Alberto , Acuña Mayorga, José Miguel , Lascano Arias, Giovanni

Efficiency and effectiveness in daily work activities demand the control of processes, those elements that can affect the health of employees known as occupational risks. The objective of this study was to identify indicators of more frequent labor risks in the countries of Uruguay, Cuba and Ecuador, for which a bibliographic compilation was carried out, as well as a descriptive analysis of the indicators of occupational risk. The results show that the countries analyzed coincide as the highest index of risks to manufacturing industries. It is concluded that the international regulations and conventions that govern safety have been accepted by the different countries that make them up, mainly in the statistical registry of accidents, reports, affiliates among others. Finally, policies aimed at the prevention, detection, monitoring and eradication of occupational risks in the workplace must be established. © 2023 IEEE.

Is Gender a Source of Measurement Variability in the General Self-Efficacy Scale? Psychometric Analysis in Ecuadorian Adults

2025 , Alexandra Salinas-Palma , Rodrigo Moreta-Herrera , Lascano Arias, Giovanni , Marco Mena-Freire , Guido Mascialino , Lucía Almeida-Márquez , Tomás Caycho-Rodríguez

To analyze whether gender is a source of variability in the General Self-Efficacy Scale (GSES) using Classical Test Theory (CTT) and Item Response Theory (IRT) in a sample of Ecuadorian adults. This is an instrumental study that assesses factorial validity and Measurement Equivalence (ME) across gender using CTT, while IRT is used to estimate item discrimination [a], difficulty [b], and differential item functioning (DIF). A total of 485 adults participated, with 44.9% male and 55.1% female, aged 18 to 53 years (M = 24.29; SD = 7.61). The unifactorial structure of the GSES was confirmed and measurement invariance was established at the thresholds (scalar) level across gender. Furthermore, there are no significant differences (p <.05) in the latent means of the groups. The item parameters for [a] and [b] were found to be adequate, with no evidence of gender-based DIF in the items. The GSES is a reliable scale for use in studies involving Ecuadorian adults, and gender does not significantly affect its measurement propertie

Suicide Risk and Social Support in Young Ecuadorian Women Victims of Violence: A Psychosocial and Educational Analysis

2025 , Lascano Arias, Giovanni , Evelyn Cuesta-Andaluz , Espinosa Pinos, Carlos Alberto

This study is part of the project entitled "Multidimensional Assessment and Intervention in Mental and Physical Health throughout the Life Cycle in the Ecuadorian Population" and its main objective was to identify the complex relationships between perceived social support, the various types of violence experienced and the sociodemographic characteristics in the context of suicide risk of women victims of violence in Ecuador. The sample consisted of 106 women victims of violence, aged between 12 and 44 years (M = 21.49, SD = 9.01). For data analysis, statistical and correlation statistics, tests of differences for independent samples, as well as cross tables (X², Cramer's V and contingency coefficient) were used. Among the most relevant findings, it was highlighted that sexual violence was the most predominant form of violence in the population studied. Additionally, a significant negative correlation was observed between perceived social support and suicide risk, positioning social support as a protective factor in this context. However, no evidence was found of a significant influence of sociodemographic factors on social support or suicide risk, so the need for additional research to delve deeper into these dynamics is discussed.
