Aim and Background: This study aimed to explain the structural model of the relationship between metacognitive beliefs and health anxiety among nurses: the mediating role of problem-focused and emotion-focused coping styles.   

Methods and Materials: The present study was descriptive, correlational, and structural equation modeling . The statistical population of this study included 250 nurses from Imam Sadeq Hospital in Delijan and Imam Khomeini Hospital in Mahallat in 1403, of from which 215 nurses were selected using convenience sampling. research instruments included the Salkouskis and Warwick et al. (1989) Health Anxiety Questionnaire, the Wells and Cartwright -Haughton Metacognitive Beliefs Questionnaire (1997), and the Endler and Parker Stress Coping Styles Questionnaire (1990). The obtained data were calculated using SPSS and LISREL software and the structural equation modeling .   

Findings: The results of the analysis showed that the hypothetical model of the research has sufficient fit and that there is an effect between metacognitive beliefs and the mediation of problem-oriented and emotion-oriented coping styles with stress and its components on health anxiety. There is a positive and significant relationship between metacognitive beliefs and emotion-oriented coping style (0.711). Also, the relationship between metacognitive beliefs and health anxiety (0.604) is also positive and significant. Also, the relationship between problem-oriented coping style and health anxiety is positive and significant with a value of 0.604, and the relationship between emotion-oriented coping style and health anxiety is negative and significant with a value of -0.484. It is worth noting that the correlation matrix between variables is significant at the p ≥0.01 level.

Conclusions: The role of anxiety as an important factor in nurses' mental health should be considered as a basis in new studies to identify the prevalence of the main symptoms of anxiety, as well as preventive measures to combat it.
