This study aimed to adapt and show evidence of validity for the Ecuadorian version of the Burnout Assessment Tool (BAT) considering only its “core” dimensions. The adaptation process included its translation and back translation. For content validation, expert reviews and focus groups were carried out. A confirmatory factor analysis was used to identify the psychometric properties and dimensionality of the scale. The reliability of the scale was assessed through the alpha, omega and composite reliability indices. To carry out the study, the questionnaire was applied to a sample of workers with a high level of education in Ecuador. In total, 2237 respondents were considered in the analysis. The results showed that the hierarchical model for BAT-23 and its short version, the BAT-12 scale, is the most adequate structure for analysis of the construct in the Ecuadorian context. The reliability of the general factor of burnout and its dimensions, evaluated by composite reliability, omega and Cronbach’s alpha, showed satisfactory indices. The findings obtained provide support for the reliability and validity of the Burnout Assessment Tool for the Ecuadorian context.

Companies are increasingly adopting practices aimed at fostering intrapreneurial initiatives to ensure their survival, seize opportunities, and combat threats. This paper analyzes the effect of employee perceptions of high-performance work systems on intrapreneurial behavior, with potential mediation by knowledge management processes. It also analyzes possible moderation by human resource management (HRM) strength. Hypotheses were tested using partial least squares path modeling (PLS-PM) in Smart PLS 3.3. The analysis was conducted for a sample of 1,885 knowledge-intensive employees working in three banks in Ecuador. The results show that innovative behavior can be enhanced by implementing high-performance work systems. These systems promote sound knowledge management processes. These findings are relevant because they offer guidance to help practitioners promote intrapreneurship. They highlight the importance of high-performance work systems that enhance knowledge management processes, particularly knowledge sharing. The results also show that HRM strength moderates the relationships between high-performance work systems and intrapreneurial behavior and between knowledge management and intrapreneurial behavior. However, in the second of these relationships, the effect is the opposite of what is to be expected. This finding may indicate a need to consider this variable at the group, department, or even organizational level under a multilevel analysis approach.

En el estudio del engagement académico se han desarrollado diversas medidas en función de las teorías o perspectivas que dan soporte a dicho concepto; en consonancia con lo anterior, el presente artículo tiene como objetivo analizar las propiedades psicométricas de una escala de engagement académico, con base en una muestra de 102 estudiantes pertenecientes a una institución de educación superior en Ecuador. El cuestionario empleado fue la versión española de la Utrecht Work Engagement Scale (UWES-S 9). Se analizó la estructura factorial de la escala con el método de estimación robusta. Los resultados obtenidos muestran que el modelo de dos factores presenta mejores índices de ajuste que el de uno y tres factores, por lo que se concluye que la estructura de dos factores es la más apropiada. De igual forma, los resultados llevan a concluir que la escala UWES-S 9 puede ser utilizada para estudiar el engagement en el contexto ecuatoriano.

El propósito de este estudio fue determinar si la intención de emprendimiento, con base en el modelo de comportamiento planeado de Ajzen (1991), puede predecirse con base en la propensión al riesgo, el locus de control interno y las habilidades de liderazgo. Asimismo, se identificaron variables sociodemográficas asociadas a tal intención. Se aplicó una batería de instrumentos estandarizados y confiables a 1493 estudiantes universitarios de áreas empresariales en cinco países latinoamericanos. De acuerdo con los resultados, la intención de emprendimiento puede predecirse significativamente con las variables estudiadas. De igual forma, se confirmó la incidencia de los antecedentes familiares en tal intención lo cual ha sido reportado en varios estudios. Contrario a lo hallado en otros estudios, no se encontraron diferencias por género en la intención de emprendimiento. Se discuten estos hallazgos.
