Abstract
Background:Human reliability assessment consists ofusing quantitative and qualitative methods to predict human contribution to the occurrence of error;so, using reliability assessment techniques is necessary to prevent and limit the consequences of errors in sensitive work environments.Healthcare considers as the high-risk areas.With due attention to the high rates of cesarean section in Iran, this study aimed at evaluating human reliability during this operation.
Materials and Methods:This was a qualitative-descriptive study which was performed as a cross-sectional one using the EMEA technique. At first, the process of operation was divided in to tasks and sub-tasks using the method of hierarchical task analysis. Then, according to the EMEA instructions, the work sheet was completed for all personnel in the operating room.
Results: A total of 126 errors, including 40 errors (31.75%) related to circular nurse activities, 34 errors (26.98%) related to anesthesia activities, 33 errors (26.19%) related to scrub nurse activities and 19 errors (15.08%) related to the activities of the surgeon, were identified.In general, skill-based errors (51.59%) and judgment-based errors (1.59%) were the highest and the lowest amount, respectively.
Conclusion:According to the study results, among three working groups, skill-based errors forcircularand scrub nurses and anesthesiology expert with the most frequency, and knowledge-based errorsfor surgeon tasks, with the highest frequency should be considered as priorities tocontrol errors.

Abstract
Background: Performance appraisal and quality evaluation of the services provided will achieve the organizational goals and improve the level of staff capability. In order to evaluate accurately and efficiently, we need to use standard indices, to compare the quality and quantity of work with standards, to know the current conditions and to solve its problems
Methods: This study is an applied study. This was done through a combined method of reviewing the texts and consensus of experts. Initially, the literature review and emergency evaluation indices were extracted, then the duplicate indices were removed and similar indices were merged, then weighted experts and questionnaires were compiled with the indices. Content validity, Cronbach's alpha coefficient and test-retest were used to assess the validity, internal consistency and reproducibility of the questionnaire, respectively. Data were analyzed using Excel and SPSS 20 software.
Finding: Final questionnaire with 105 questions in 8 areas including management and leadership (15); human resources (22); physical space and facilities (18); medicine and medical equipment (6); guidelines and policies (17); patient-centered (10); documentation of patient records (5); quality and time indices in the emergency department (12). The results showed that the final questionnaire was reliable (0.89) and repeatable (ICC = 0.98).
Conclusion: The Hospital Emergency Performance Assessment Questionnaire is a valid and reliable instrument and can be used to evaluate the performance of hospital emergency services.

Abstract
Background and Objectives: the purpose of this study was to assess the validity and reliability of the Yas Job Satisfaction Questionnaire in order to develop a useful tool for measuring and evaluating job satisfaction among Yas Hospital Complex staff.
Materials and Methods: Face validity, content validity ratio, and content validity index were used to evaluate the questionnaire's validity and reliability. Cronbach's alpha and the halving technique were used among 150 medical personnel in this cross-sectional study The key elements of the final questionnaire were four dimensions of leadership style, job nature, reward system, performance appraisal, and organizational climate.To report the mean of quantitative variables at different levels, qualitative factors were evaluated and analyzed using analysis of variance (ANOVA).
Results: There were 111 females and 39 males among the 150 participants. The content validity ratio and content validity index were both acceptable.Cronbach's alpha method reported a reliability of 0.92 for the questionnaire, indicating that the internal reliability is acceptable.The lowest level of satisfaction was in the leadership style dimension, with an average of 10.53 4.91, while the highest level of satisfaction was in the job nature dimension, with an average of 21.24 7.05.
Conclusion: The Yas Job Satisfaction Questionnaire has acceptable validity and reliability to assess the level of job satisfaction among medical staff, according to the findings of this study. Furthermore, job satisfaction was moderate in most of the dimentions surveyed.

Abstract
Background and purpose: Assessing job satisfaction within any organization is essential due to its impact on productivity and overall effectiveness. This study aimed to evaluate the validity and reliability of the Persian version of Spector's Job Satisfaction Questionnaire among employees of emergency medical centers.
Methods: This descriptive-analytical study was conducted among 270 employees of emergency medical centers in Ahvaz between February 2021 and June 2021. Data collection was performed using a census method and Spector's Job Satisfaction Questionnaire. Face validity, content validity, and translation accuracy of the questionnaire were reviewed by experts. Convergent and divergent validity and reliability were assessed using factor loadings, average variance extracted (AVE), reciprocal factor loadings, Cronbach's alpha, and composite reliability in SMART-PLS 3 software.
Results: The face validity, content validity, and translation accuracy of the questionnaire were confirmed by experts to suit the Iranian context. All item factor loadings and the AVE index for all constructs exceeded 0.4. The AVE index for the entire questionnaire was 0.523. Examination of reciprocal factor loadings confirmed divergent validity. Cronbach's alpha and composite reliability indices for all constructs were above 0.7. The Cronbach's alpha coefficient and composite reliability for the entire questionnaire were 0.83 and 0.88, respectively.
Conclusion: The validity and reliability of this questionnaire, as adjusted for the Iranian population, were confirmed to be high. Therefore, this questionnaire can be effectively used to evaluate job satisfaction among employees in various organizations, particularly in healthcare organizations and centers.
