| Summary: | 碩士 === 中原大學 === 心理學研究所 === 99 === Research background & aim: To comprehensively understand the impact of chronic fatigue and work locus of control on work effectiveness, so the study has two purposes. First, investigating whether or not chronic fatigue and accompanying symptoms have negative effect on work effectiveness, such as reducing positive work performances, or increasing negative work performances；second, examining the moderating effect of work locus of control on chronic fatigue and work effectiveness.
Methods: Participants were 246 full-time workers. All participants completed paper questionnaires including the demographic data, Checklist Individual Strength, CDC symptom inventory for assessment of chronic fatigue syndrome, Medical Outcomes Survey Short Form-36, Work Locus of Control Scale, Cynicism Scale, Organizational Commitment Scale, Organizational Citizen Behavior Scale, and Organizational Withdrawal Scale . All data were statistically analyzed using descriptive statistics, t-test, ANOVA, Pearson’s correlation test, and multiple hierarchical regression analysis.
Results: Multiple regressions showed that chronic fatigue is statistically significant negative predictors of work effectiveness. When workers experienced chronic fatigue, it would reduce their positive attitude and behavior at work, and increase negative work attitude and behavior. The interaction of chronic fatigue and work locus of control has different outcome to work attitudes and behavior.
Discussion: Chronic fatigue not only negatively influence daily life and work to individuals, but also is a secondary stressor, and will form a vicious circle to a worse consequence. To prevent this bad result, organizations should provide more support and resources to workers coping with work stress. And to chronic fatigued workers, CBT is an effective intervention to improve the influence of chronic fatigue.
