Previous research stresses that system justifying belief can weaken corruption perception, by this possibly fostering unjust behaviors. However, general results of the effect of general system justification on corruption are ambiguous, indicating also a lessening impact. We conducted a line of studies trying to elucidate these circumstances by testing the effect of general system justification on corruption perception and intention. In addition, we explored institutional trust as a possible mediator in this process. For this purpose, we conducted three studies. The first two studies examined the association between general system justification and corruption. In Study 1, a correlational design was run using questionnaires to assess the relation between general system justification and corruption perception as well as corruption intention. In Study 2, an experimental design was conducted manipulating general system justification via exposure to high or low system threat condition, then measuring its effect on corruption perception and corrupt intention. In Study 3, two sub-studies using correlational and experimental designs were run to explore the mediating role of institutional trust, respectively. Results replicated former studies showing that general system justification is negatively associated with corruption perception. However, they also showed a negative correlation with corrupt intention. Furthermore, they showed that institutional trust mediated the relation between general system justification and corruption. We suggest to consider these findings to further elucidate the psychological basis underlying different effects of general system justification on human behaviors.
The present set of studies aimed to explore the effect of self-esteem on corrupt intention and the mediating role of materialism in generating this effect. In Study 1, we used questionnaires to investigate the correlation among self-esteem, materialism, and corrupt intention. In Study 2, we manipulated self-esteem to explore the causal effect of self-esteem on materialism and corrupt intention. In Study 3, we manipulated materialism to examine whether inducing materialism can reduce the relationship between self-esteem and corrupt intention. The three studies converged to show that increased self-esteem caused a low level of materialism, which in turn decreased corrupt intention. The theoretical and practical implications of the results are discussed.
Introduction: Despite the growing body of cross-sectional research linking sleep problems and school burnout, hardly any research has investigated the longitudinal relationship between these two constructs. The aim of this study was to examine the bidirectional association between sleep problems and school burnout in middle school students. Methods: A prospective design was used incorporating four time points (approximately 6-month interval). The participants were 1226 (50.3% girls) middle school students from 4 public schools who were in 7th grade at baseline. On average, participants were approximately 12.5 years old at the beginning of the study (M age = 12.73, SD = 0.68). All participants completed selfreport measures in classrooms during regular school hours. The data were analyzed using a crosslagged structural equation model. We also examined the stability of sleep problems and school burnout in time, and investigated the moderating role of gender. Results: The results indicated there is a moderate stability for both sleep problems and school burnout, and those students with sleep problems were more likely to develop school burnout, and vice versa. Gender did not moderate the bidirectional relationship. Conclusions: These results suggest that future studies should investigate whether implementing intervention for sleep problems can decrease the occurrence of school burnout and whether interventions targeting school burnout can improve sleep problems.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
