“Background: The study of the meaning of life is essential since it plays a protective role in the mental health of university students. However, no studies have shown the adequate psychometric functioning of the MLQ in Latin American university students. For this reason, this research aims to evaluate the internal structure using CTT models, obtain evidence of validity based on the relationship with other variables, perform factorial invariance according to gender, and estimate the reliability of the MLQ. Methods: A sample of 581 Peruvian undergraduate students of both sexes (29.5% men and 70.5% women) between the ages of 18 and 35 (M=22.6; SD=3.3) was collected. Along with the MLQ, other instruments were applied to measure satisfaction with life (SWLS), subjective well-being (WBI), and depression (PHQ-9). Results: In the present study was evidenced that the model of two related facto...

El objetivo del presente estudio fue evaluar las propiedades psicométricas de la Escala de autoestima de Rosenberg-P (EAR-P). Específicamente, evaluar la estructura interna, la consistencia interna y las evidencias de validez basada en la relación con otras variables. Para ello fueron evaluados 797 universitarios peruanos de los cuales 235 fueron hombres (29.49%) y 562 mujeres (70.51%) con un rango de edad de 18 a 35 años (M=22.55, DS=3.32). Los resultados indican que la estructura unidimensional de la EAR-P presenta adecuados índices de ajuste (CFI=.98, TLI=.97, SRMR=.05) y un aceptable valor en la consistencia interna (ɷ = .96; α =.97). Además, se encontró que la EAR-P mostró evidencias de validez relacionada con otras variables. Por tanto, se concluye que la EAR-P presenta adecuadas propiedades psicométricas de validez y confiabilidad, esto permite contar un instrumento út...

El objetivo fue evaluar la estructura factorial y analizar el efecto de método asociado a los ítems negativos de la escala EAR. Para ello, se planteó una versión A (ítems positivos y negativos) y una versión B (solo ítems positivos). Se recolectó una muestra de 350 universitarios para cada versión. El AFC evidencia que el modelo unidimensional (A1) de la versión A, no presentan adecuados índices de ajuste. También se encontró que añadir un factor específico para ítems negativos (modelo A2) y otro factor para ítems positivos (modelo A3) no mejora los índices de ajuste. Un modelo bidimensional (modelo A4), tampoco mejorar los índices de ajuste. Respecto al modelo unidimensional de la versión B, este presenta un ajuste superior frente al modelo original (modelo A1). Se concluye que la versión B, mide adecuadamente la autoestima ya que no tiene ítems negativos y además...

La hipertensión arterial es una enfermedad crónica con alta prevalencia mundial. A pesar de los tratamientos farmacológicos disponibles, la falta de adherencia al tratamiento representa un desafío importante. La Escala de Adhesión a Reposiciones y Medicamentos (ARMS) es una herramienta prometedora para evaluar la adhesión al tratamiento, pero carece de propiedades psicométricas en Perú. Frente a ello la investigación tuvo como examinar las propiedades psicométricas del ARMS en pacientes con hipertensión arterial de centros de salud de Lima Este. La investigación fue de tipo instrumental y la muestra estuvo conformada por 367 participantes (48.77% hombres y 51.23% mujeres) con una edad que oscilaba de 35 a 80 (M=64.11; DS=9.49). Se evaluó la validez de contenido, validez basada en la estructura interna mediante un análisis factorial confirmatorio, invarianza de medición seg...

“Introduction. The objective was to evaluate the factor structure and propose a new version of the Rosenberg Self-Esteem Scale with only positive items to overcome the method effect associated with negative items. Method. A version A (positive and negative items) and a version B (only positive items) were considered. A sample of 350 university students was collected for each version. Results. The CFA shows that version A's one-dimensional model (A1) does not present adequate fit indices. It was also found that adding a specific factor for negative items (model A2) and another factor for positive items (model A3) does not improve the fit indices. A twodimensional model (A4 model) does not improve the fit indices either. Regarding the onedimensional model of version B, it presents a superior fit compared to the original model (model A1) Discussion and Conclusions. It is concluded that ve...

Background: Depression and anxiety are two of the most prevalent and disabling mental disorders worldwide, both in the general population and in outpatient clinical settings. Objective: This study aimed to analyze the psychometric properties of the Patient Health Questionnaire-4 (PHQ-4) based on network analysis metrics. Methods: A total of 911 Paraguayans (23.71% women and 76.29% men; mean age 31.25 years, SD = 10.63), selected by non-probabilistic convenience sampling, participated in the study. Network analysis was used to evaluate the internal structure, reliability, and measurement invariance between men and women. Results: The results revealed that the PHQ-4 is a unidimensional measure through Exploratory Graph Analysis (EGA). Reliability, through structural consistency, identified that 100% of the time, only a single dimension was obtained, and all items remained stable, as they w...

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 ...
