RESUMO
OBJECTIVES: To assess the association between the mental health of caregivers having a psychiatric patient at home and work fatigue, and if this association is moderated by spirituality. METHODS: This case-control study enrolled 600 caregivers (July-September 2019). RESULTS: Stress, anxiety, insomnia and the presence of a psychiatric patient at home were associated with higher levels of physical, mental, and emotional work fatigue. In the case of caregivers who have a psychiatric patient at home, those with low spirituality had more mental and emotional work fatigue. PRACTICAL IMPLICATIONS: Healthcare professionals should enlighten caregivers more on the risks and the consequences of their job, assist them with information on what to expect, and teach them how to normalize feelings that they may face.
