The mediating role of work-family conflict in the relationship between organizational justice and work-related stress / Rol mediador del conflicto trabajo-familia en la relación entre justicia organizacional y estrés laboral

Abstract Although the effects of overall organizational justice on perceptions of work-related stress have been demonstrated in previous studies, the mechanisms underlying this relationship are not explicit. Current research suggests that supervisors who are perceived as fair enhance employees' ability to balance their work and family roles, positively impacting their stress levels. The aim of this research is to examine the mediating role of work-family conflict in the relationship between perceptions of overall organizational justice and work-related stress in a Latin-American work context; also analyze gender differences in work-family/work-family conflict. 129 workers belonging to a Chilean public institution participated and answered a self-report questionnaire. Analyses were done using bivariate correlations of Pearson, Tau-b of Kendall, Student t-test and structural equation modeling. The results showed the existence of a significant negative correlation between perceptions of overall organizational justice and work-related stress. Furthermore, this relationship was partially mediated by work-family conflict, which means, perceptions of organizational justice were directly and indirectly associated with work-related stress, through work-family conflict. With respect to the gender variable and the work-family, no significant differences were found. This study contributes empirical evidence regarding the importance of perceptions of overall organizational justice and the work-family conflict on work-related stress, and the results obtained guide the diagnosis and the design of more specific models of prevention and intervention from the perspective of occupational health psychology.

Resumen Si bien los efectos de las percepciones de justicia organizacional global sobre las percepciones de estrés laboral han sido demostrados en estudios previos, los mecanismos que subyacen a esta relación no resultan explícitos. La investigación actual plantea que las jefaturas percibidas como más justas potencian la capacidad del trabajador para conciliar sus roles laborales y familiares, impactando positivamente sus niveles de estrés. El objetivo de este estudio es analizar, en un contexto laboral latinoamericano, el rol mediador del conflicto trabajo-familia en la relación entre las percepciones de justicia organizacional global y estrés laboral; y analizar diferencias entre hombres y mujeres respecto al conflicto trabajo-familia. Participaron 129 trabajadores pertenecientes a una institución pública chilena, quienes contestaron un cuestionario de autoreporte. Se efectuaron correlaciones bivariadas de Pearson, Tau-b de Kendall, prueba t de Student y modelamiento de ecuaciones estructurales. Los resultados mostraron la existencia de una correlación negativa y significativa entre las percepciones de justicia organizacional global y el estrés laboral. Además, esta relación estuvo mediada parcialmente por el conflicto trabajo-familia, es decir, las percepciones de justicia organizacional se asociaron de manera directa e indirecta al estrés laboral, a través del conflicto trabajo-familia. Respecto de la variable género y el conflict trabajo-familia, no se encontraron diferencias significativas. Este estudio aporta evidencia empírica sobre la importancia de las percepciones de justicia organizacional global, y sus resultados orientan el diagnóstico y la elaboración de modelos de prevención e intervención más específicos desde el campo de la psicología de la salud ocupacional.

The Relationship between Depression, Attention Deficit/Hyperactivity Disorder, and Internet Gaming Disorder Through Mediation Model

OBJECTIVES: Internet gaming disorder (IGD) is associated with attention deficit/hyperactivity disorder (ADHD) or depression etc. We tried to examine the mediating effects of depression in the relationship between ADHD and IGD.METHODS: This study was conducted on 2000 people who participated in on-line survey among 14–39 year-old men and women in 2017. And we clarified the relationship among IGD, ADHD, and depression and tested the mediation model. The mean and standard deviation of the main variables were calculated and correlation analysis was performed to confirm the relationship among the main variables. In order to test the mediating effect of depression on the relationship between ADHD and IGD, the structural equation model was implemented using AMOS 21 (IBM).RESULTS: There were significant correlations among the variables; IGD, ADHD and depression. Depression had a mediating effect 0.23 (95% confidence interval : 0.17–0.28) in the relationship between IGD and ADHD.CONCLUSIONS: This study showed that depression can mediate ADHD and IGD. Therefore, the evaluation and management of depression and ADHD should be included in the diagnosis and treatment of IGD.
