Objective: This study examined the effects of nomophobic behaviors of surgical nurses on time management and psychological well-being. Background: Addicted use of smartphones in the working environment is a social disease defined as nomophobia. Methods: This is a descriptive and cross-sectional study. This study was conducted between December 2018 and March 2019 at a university hospital located in Turkey. 314 nurses who met the inclusion criteria formed the sample of the study. Results: A statistically significant relationship was found between the sub-dimensions of the Nomophobia Scale and psychological well-being (p < .05). The stepwise regression analysis, which was conducted to examine the effects of independent variables on the sub-dimensions of the scales, showed statistically significant correlations. Conclusions: Nomophobia prevents patients from communicating effectively with health professionals, leads to misunderstandings and reduces the amount of work per unit time and the quality of work.
