(1) Background: The Acceptance and Action Questionnaire-II (AAQ-II) is the most well-known self-report measure to assess psychological inflexibility, a transdiagnostic pathological process, and targets for interventions. Objective: The aim of this study was to analyze the psychometric properties and factorial structure of the Ecuadorian Spanish version of the AAQ-II in a large sample of college students in Ecuador. (2) Methods: A total of 7905 students, 46.26% male and 53.75% female, from 11 Ecuadorian universities were surveyed. The AAQ-II was tested for factorial structure, reliability, and correlations with other health-related measures. (3) Results: The AAQ-II showed an unidimensional factorial structure, accounting for 66.87% to 70% of the total variance and showing a good fit of the data to the model (comparative adjustment index (CFI) = 0.995; goodness of fit index (GFI) = 0.992; Standardized Root Mean Squared Residual (SRMR) = 0.037; mean square approximation error (RMSEA) = 0.047, CI90% = 0.038–0.056). Reliability was optimal (Cronbach’s α = 0.919; ω = 0.928), and AAQ-II scores significantly correlated with multiple health indicators. Psychological inflexibility was significantly higher in women than men. (4) Conclusions: The Spanish version of the AAQ-II showed good psychometric properties, which further supports psychological inflexibility, not just as a transdiagnostic process.

The Alcohol Use Disorders Identification Test (AUDIT) is the gold standard in assessing harmful alcohol intake, which is responsible for substantial morbidity and mortality. The goal of this study is to evaluate the psychometric properties and factor structure of an Ecuadorian adaptation of a Spanish translation of the AUDIT in a large sample of college students in Ecuador. A total of 7905 students, including 46.26% males, and 53.75% females, from 11 universities in Ecuador, were surveyed. The questionnaire was tested for two- and three-factor structures, reliability, and correlations with other health related measures. The Kaiser-Meyer-Olkin test for sampling adequacy was satisfactory (.0885), and Bartlett´s test for sphericity was significant (p < .001). Although both models showed a good fit to the data, the two-factor model was preferred based on the high correlations between the factors 2 and 3 within the three-factor model (.86 for the total sample, .77 for females, and .91 for males). The reliability for the two-factor model was good, as indicated by Cronbach´s α = .806 (factor I) and .716 (factor II) for the total sample, .808 (factor I) and .667 (factor II) for females, and .787 (factor I) and .728 (factor II) for males. Additionally, the AUDIT scores positively correlated with several health-related measures: stress, psychological inflexibility, loneliness and depression/anxiety symptomatology. The Ecuadorian adaptation of the Spanish version of the AUDIT has good reliability, and internal consistency and correlates with other health related measures, proving to be a reliable tool that can be used by researchers and clinicians to screen hazardous alcohol intake in college students.

Background: Although the use of technology is a trend, since the COVID-19 pandemic, its use has been exacerbated, especially in educational processes, causing techno-stress among teachers. Purpose: In order to contribute to the lack of validated and adapted instruments in Latin America, this study aimed to analyze the psychometric properties and factorial structure of the Spanish version of the technostress scale in a large sample of Ecuadorian teachers. Methods: A non-probabilistic intentional sample of 2850 teachers (mean age 40 years, SD= 9.65; 65% female) from various schools throughout the Ecuadorian territory was surveyed online using a cross-sectional design. Data analysis included exploratory (EFA) and confirmatory factor analysis (CFA), factorial invariance, assessment of internal consistency, sex differences in technostress scale scores and convergent validity. Results: The EFA yielded a structure of four factors: skepticism, fatigue, anxiety and inefficiency. Through CFA, the hierarchical model that included a general factor and four nested factors had a better fit, and that model remained invariant across sex, age and public and private institutions. Total omega value (ω) was 0.962 for the total scale and hierarchical omega values (ωh) were 0.886 for the general factor, as well as 0.30, 0.22, 0.12 and 0.21 for the respective nested factors (skepticism, fatigue, anxiety and inefficiency). Moreover, the Resources, Experiences, Demands for Information and Communication Technologies (RED/TIC) scores were significantly higher among women, although effect sizes of comparison of those sex differences were very small. Finally, the RED/TIC scores correlated with the Depression, Anxiety and Stress Scale (DASS-21). Conclusion: The RED/TIC scale has adequate psychometric properties in primary and high school teachers, and its use in that population is supported, which provides a valuable tool for the evaluation and detection of technostress in teachers and facilitates the investigation of this multifactorial phenomenon in Latin America.

La gran demanda, el fácil acceso y el tiempo de dedicación a los videojuegos por parte de los adolescentes han causado consecuencias no beneficiosas por su uso excesivo, convirtiéndose en un problema social, por esta razón resulta pertinente conocer su prevalencia en el contexto ecuatoriano, además de explorar su relación con algunas variables sociodemográficas. La presente investigación comprende un estudio no experimental, ex-post-facto, comparativo y transversal, realizado en una muestra de 3.178 estudiantes de secundaria de 76 instituciones educativas del Ecuador, de los cuales el 52,8% fueron hombres y el 47,2% mujeres, entre 14 y 17 años (15,62±0,80). Los resultados arrojaron una prevalencia baja de uso problemático de videojuegos (1,13%), los adolescentes hombre y que residían en zonas urbanas tuvieron una mayor probabilidad de presentar un mayor uso problemático de videojuegos. La edad, el tipo de institución educativa y el tipo de familia no se relacionaron con el uso problemático de videojuegos. Estos hallazgos respaldan la necesidad de generar intervenciones eficaces que atienda la demanda de usuarios que presenten una mayor tendencia a usar dispositivos de videojuegos de manera excesiva.

El objetivo de la presente investigación fue verificar la influencia de factores individuales como la edad, el sexo, el nivel socioeconómico, y factores protectores como la resiliencia, la autoeficacia generalizada y el apoyo social percibido sobre los estilos de vida saludable, en personas con riesgo cardiovascular, además de sus posibles interacciones. Se utilizó una muestra de 290 personas, compuesta por 140 hombres y 150 mujeres, con edades comprendidas entre 35 y 65 años. A través de un análisis de ruta, se obtuvo que las variables con mayor predicción sobre el estilo de vida saludable fueron el apoyo social percibido, específicamente de amigos, y la resiliencia. Así mismo, se encontró que la autoeficacia influye significativamente sobre la resiliencia, y el apoyo social percibido es un predictor relevante para la primera. En conclusión, el estilo de vida saludable se puede predecir en gran medida por variables de contenido psicológico, de forma directa e indirecta. Además, puede verse diferenciado dependiendo de la dimensión específica de la variable predicha y el número de variables que se relacionen en conjunto.
