“…Los modelos de ajuste se probaron de acuerdo a los indicadores absolutos, como el chi cuadrado (χ 2 ), el chi cuadrado normado (χ 2 /gl) y el Residuo Cuadrado Medio Estandarizado (SRMR); los indicadores relativos, Índice de Ajuste Comparativo (CFI) y el Índice de Tucker-Lewis (TLI); y el indicador no basado en la centralidad, Error Cuadrático Medio de Aproximación (RMSEA). Se consideran ajustes adecuados cuando el χ 2 no es significativo (p > .05) o el χ 2 /gl es menor a 4; el CFI y el TLI son superiores a .95; el SRMR y el RMSEA inferiores a .08 y las saturaciones (λ) superiores a .50 (Brown, 2015;Byrne, 2006;Domínguez-Lara, 2018;Moreta-Herrera et al, 2022;Mueller & Hancock, 2018;Wolf et al, 2013).…”

La autorregulación del aprendizaje (ARA) y la autoeficacia académica (AA) forman parte de la teoría social cognitiva y del aprendizaje, y cumplen un rol fundamental en el contexto educativo. Este trabajo tiene por objetivo identificar el potencial explicativo de la ARA en la AA en una muestra de estudiantes universitarios del Ecuador. Se utilizó una metodología cuantitativa, descriptiva y explicativa por medio del modelo de ecuaciones estructurales (SEM). La muestra la comprenden 570 estudiantes de dos universidades públicas del Ecuador. El 76 % son mujeres y el 24 % son varones, con edades entre los 17 y los 56 años (M = 25.29). Los resultados reflejan que existe una correlación positiva y moderada entre la ARA y la AA. Además, no se presentan diferencias significativas por género (p > .05) en ambos atributos. A nivel de influencia, la ARA explica en un 23.8 % los cambios de la varianza de la AA mediante de técnicas SEM. Se concluye que la ARA es un predictor moderado de la AA en universitarios del Ecuador.

“…The analysis of discrimination and difficulty of items was performed using a Graded Response Model (GRM). This is an extension of the 2-Parameter Logistic Model (2-PLM) for ordered polytomous items [48][49][50]. In the discrimination parameter, the slope of change of the answers to the items is analysed based on the level of ability that the person has.…”

The Kessler psychological distress scale is a useful tool for identifying possible psychological problems and has been widely used in research and health services. Unfortunately, its application in various populations has not always been psychometrically supported. For this reason, the present study investigated the psychometric properties of its Spanish version in adolescents, verifying its factorial structure, measurement invariance by gender, internal consistency and the discrimination and difficulty parameters of its items according to the Item Response Theory (IRT). A sample of 5132 Ecuadorian adolescents was evaluated. The sample is equally distributed between male and female participants (50%) and basic and higher education (51% the former). All participants were between 11 and 20 years old. The results show that a 9-item version with correlated intercepts presents the best fit. In addition, it is invariant by gender at a strict level and has adequate internal consistency. IRT analyses indicated that all the items, except for item eight, present adequate discrimination and difficulty. Based on these results, we conclude that the 9-item version of the Psychological Distress Scale is the most appropriate for this population.

“…The only exception is the work of Caycho-Rodríguez et al (2022b), which concludes that the PIL-SF items have adequate discrimination and difficulty, especially the item "Presence of goals/purpose in life" (item 20), which is the best discriminator and shows greater precision in the latent variable. The use of IRT allows a better understanding of the mechanism by which a measure manages to assess a specific construct (Hambleton et al, 2010;Moreta-Herrera et al, 2022). Thus, the use of CTT and IRT provides more precise information about the evaluative capacity of a measure.…”

Introduction: The purpose in life is analyzed within psychological well-being, it deals with the meaning of life that people have, which has implications in areas such as mental health. Currently, precise instrumentation is required for its assessment of the Ecuadorian population, which at the moment is limited. Objective: To corroborate the unidimensional structure of the Purpose in Life Scale-Short version (PIL-SF), the equivalence of measurement according to gender, the reliability and the parameters of discrimination and difficulty in a sample of Ecuadorian adults. Methods: Instrumental study of the PIL-SF under the precepts of Classical Test Theory and Item Response Theory. Participants: 743 Ecuadorian adults (64.2% women and 45.8% men) aged 18 to 73 years (M = 24.7, SD = 7.9). Results: The unifactorial structure of the PIL-SF with adequate adjustment was confirmed. In addition, the PIL-SF is invariant at the strong level based on gender and no differences are presented at the level of latent means. The internal consistency reliability is acceptable per group and the discrimination and item difficulty parameters are adequate. Conclusion: The PIL-SF is a valid, reliable, and accurate tool to measure the Purpose in Life construct in Ecuadorian adults.
