Furthermore, it was discovered that a healthier lifestyle had a greater impact on lowering chronic fatigue (&beta; = -0.393, p < 0.001). An acceptable fit was shown by the model fit indices (SRMR = 0.080, NFI = 0.928, R²= 0.42). Furthermore, the moderating effect of a healthy lifestyle was validated, showing that increased participation in healthy behaviors lessened the effect of emotional exhaustion on chronic fatigue.</span></span></span></span></span><br> <span style="font-size:11pt"><span style="line-height:115%"><b><span style="font-size:10.0pt"><span style="line-height:115%"><span style="letter-spacing:-.1pt">Conclusion:</span></span></span></b><span style="font-size:10.0pt"><span style="line-height:115%"><span style="letter-spacing:-.1pt"> The results showed that a health-promoting lifestyle can play a moderating role in the relationship between emotional exhaustion and chronic fatigue in nurses; therefore, paying attention to factors affecting the increase in a health-promoting lifestyle can be considered in improving the conditions of nurses who are exposed to burnout and chronic fatigue and improve their performance.</span></span></span></span></span></span><br> &nbsp; Emotional exhaustion, Chronic fatigue, Health-promoting lifestyle, Nurses. 1615 1624 http://sbrh.ssu.ac.ir/browse.php?a_code=A-10-98-3&slc_lang=en&sid=1 Amin Barazandeh aminbar.psy@gmail.com No Department of Psychology, Faculty of Educational Sciences and Psychology, Islamic Azad University, Isfahan Branch (Khorasgan), Isfahan, Iran Maedeh khorasani khorasani766@gmail.com No Department of Psychology, Faculty of Educational Sciences and Psychology, Islamic Azad University, Isfahan Branch (Khorasgan), Isfahan, Iran Molouk Tahmasebi tahmasebi.molouk@yahoo.com No Department of Human Resources, Faculty of Educational Sciences and Psychology, University of Isfahan, Isfahan, Iran Mohammadhadi Farahzadi h.farahzadi@ssu.ac.ir 0000-0003-1905-6891 Yes Department of psychiatry, Research center of addiction and behavioral sciences, Shahid Sadoughi, University of medical sciences, Yazd, Iran Sara Fazeli 0009-0002-8008-1340 No Faculty of Educational Sciences and Psychology, Department of Clinical Psychology, Alzahra University, Tehran, Iran
