Background: With the emergence of Middle East respiratory syndrome (MERS), health care preparedness has received increasing attention, which requires valid tools to assess the knowledge and attitude of health workers, such as nurses, with regard to this disease. Aims: This study aimed to develop and evaluate a knowledge and attitudes questionnaire on MERS coronavirus for Iranian nurses. Methods: A questionnaire was developed based on international and national guidelines and a literature review. Ten nurses were recruited to assess face validity and 11 experts reviewed the instrument to determine the content validity ratio and index. Exploratory factor analysis was then done with a random sample of 155 nurses in Tabriz city, Islamic Republic of Iran. Results: Following determination of face and content validity, 78 items (61 knowledge and 17 attitude) were retained in the final version of the questionnaire. The knowledge scale had an average content validity index of 0.80 and the attitude scale a value of 0.91. In the exploratory factor analysis, five dimensions with eigenvalues > 1 and loading level ≥ 0.4 were extracted for the knowledge scale (46 items) and two for the attitude scale (16 items). The Kuder-Richardson 21 coefficient and intraclass correlation coefficient for the knowledge scale were 0.94 and 0.91 respectively. In the attitude scale, the Cronbach alpha coefficient and intraclass correlation coefficients were 0.82 and 0.89 respectively. Conclusions: The scale developed in this study is reliable and stable and a suitable instrument for evaluating the knowledge and attitude of nurses about MERS-CoV.

Introduction: Occupational stress is one of the most important phenomena in the workplace. Mental health, as an important factor in all personal, social, and occupational life aspects, is one of the areas of interest in mental health. The purpose of this study was to determine the relationship between job stress and mental health among workers of central iron ore in Bafgh City, Iran. Methods: This was a descriptive correlational study. The statistical population included 2400 people (1600 workers and 800 employees) working in central Bafgh iron ore in 2014. The sample size was estimated as 331 using the Morgan and Krejcie table. Approximately, 216 persons were employed in the labor sector and 115 in the employment sector. Data collection tools included the Goldberg general health questionnaire (GHQ) and Depression Anxiety Stress Scales (DASS). The DASS was designed in three parts. The first part included demographic data (7 items). The second section had 28 questions and dealt with the participants' general health status. The third part included 42 questions and was about occupational stress. Later, Spss21 was used and Pearson correlation coefficient and regression tests were run to analyze the data and test the hypotheses. Results: The results showed that mental health was higher in employees, while job stress was higher among the workers. This indicated a significant association between job stress and mental health in both employees and workers. However, regarding the demographic variables, only gender was related to mental health and rest of the demographic variables had no significant relationship with mental health and job stress (5≥participants). Conclusion: Occupational stress was related to mental health in employees and workers; this can affect the level of production and product quality. Furthermore, occupational tress and mental health not only affect the workers and employees, but also expose the society and other people at risk.  Consequently, it is necessary to plan and render different services at the occupation environment to decrease job stress and improve the current situation.

1397 ‫بهار‬ ‫اول،‬ ‫شماره‬ ‫هفتم،‬ ‫دوره‬ ‫هفتم،‬ ‫سال‬ ‫پرستاري‬ ‫مديريت‬ ‫فصلنامه‬ (r=0/315), perceived organizational support (r=0/497) and servant leadership (r=0/382) had a positive and significant relationship with work engagement of nurses. Also the predicted variables significantly could predict 52/9 percent of variance of nurses' work engagement that the share of perceived organizational support was higher than other variables (p≥0/01). Conclusion: In order to findings, it is suggested that all nurse managers and also other health care administrator make supportive atmosphere by applying servant leadership. If programs planned in regard to these objectives would be improved nurses' work engagement.
