Introduction: All medical professionals are exposed to a large amount of stressful situations in their daily work. Previous research has shown that especially high levels of stress are exposed to medical staff in the outhospital emergency service, employees of the hospital emergency service and employees in intensive care units. The emergence of the COVID 19 pandemic, in addition to causing increased levels of stress among health professionals due to concern for the health of their own family members, also causes a certain level of concern and anxiety for their family members themselves. The aim of the study was to determine the impact of the COVID 19 pandemic on emotional, cognitive and behavioral reactions to stress and quality of life in family members of ZZHM employees in Karlovac County during the COVID19 pandemic. Methods: A total of 114 subjects participated in the study. The survey was conducted through an online questionnaire among family members of health professionals living with them in a joint household. Respondents completed a questionnaire consisting of a demographic questionnaire, a questionnaire related to COVID-19, a questionnaire on stress determinants that may be affected by constant contact with a family member / partner working with COVID-19 patients, and a quality questionnaire. of life - MANSA questionnaire Results: 40.4% of respondents do not feel fear for their own health at all due to contact with a family member / partner working with patients with COVID 19. No statistically significant difference was found in emotional responses to stress in respondents by gender, age, education level and family connection with an employee of ZZHM. Employees showed the lowest degree of fear for their own health. Subjects who survived COVID 19 and had a statistically significantly higher level of difficulty concentrating. All respondents in the research are mostly satisfied with the quality of life. Respondents who have no fear of COVID infection at all are more satisfied with their lives on all parts of the questionnaire. Conclusion: In addition to the need to identify signs of stress in health care workers in time, it is necessary to provide the necessary support to their families. The findings of this study need to be viewed with a dose of limitation due to the size and structure of the subjects, but this study can serve as an example for further research on stress and emotional change in healthcare families regardless of the COVID 19 pandemic .
