The present study investigates the effect of audit report quality on user behavior. The purpose of this study is to investigate the effect of reporting, legal and language structure of audit reports on user behavior. The present study is an applied research in which descriptive-correlation is used as a methodology. Additionally, data collection is by Delphi method. Audit reports were qualitatively evaluated based on a researcher-made checklist. Finally, to measure the behavior of users of audit reports, both the information inferred from financial reports and data of the returns obtained by investors were used. The structure of audit reports is studied based on the requirements of audit reporting standards, the legal structure is studied based on the provisions of the laws governing the duties of auditors and statutory auditor, and the language structure is studied based on the tone and explicitness of audit reports. Findings show a correlation between user behavior and audit reporting standards and language structure (tone and explicitness). Furthermore, findings show that not only institute’s ranking in both securities and exchange organization and association of certified public accountants, but also audits experience, do not effect user behavior. Meanwhile, audit report quality ranking and score is positively related with user behavior. In conclusion, these assumptions confirm the concept of substance over form in audit reports.

The present study was conducted to analyze the Scientific Collaboration Networks and visualization the science map of papers on the subject of audit fees published in the journals approved by the MSRT. This research is of applied type and has been done by using co-occurrence analysis of words (network analysis,Co-Word,and Co-authorship). The research community is formed by245papers published from 2003-2022, which were analyzed and visualized using VOSviewer, Ucinet, and BibExcel software. The results showed that between 2019&2021, with the publication of108papers(44%),there was a revolution in the publication of audit fees research in Iran, and the scientific journal of professional audit research, with23%of published papers on this topic, had the greatest tendency to audit fees. The writing confusion and diversity in the Persian language have led to the use of49written and semantic equivalents for audit fees in previous researches, which warns of the necessity of its optimization by journals and researchers. Co-Word analysis indicates that998keywords are used in the articles, after audit fees(193),the most frequent words are audit quality(34),audit risk(21),and abnormal audit fee(21). The keywords audit quality and audit risk with 24&20co-occurrences had the highest co-occurrence with audit fees. The analysis of co-authorship shows the existence of643authorship roles in papers on the topic of audit fees,and Ali Vaez and Vali Khodadadi with11&10papers published,and the ShahidChamran University and Ferdowsi University with68&44 repetitions of organizational affiliation among authors can be considered as the most specialized researchers and organizations among others. There was the most co-writing between Mostafa Abdi and Mahdi Kazemi with5duo collaborations.

Various factors affect the auditor's professional judgment and decision-making. One of these factors is the auditor's narcissism. Given to role of auditor's judgment and decision-making in audit quality and the impact of auditors' psychological characteristics on their judgment, the purpose of this research is to investigate the role of auditor's narcissism on unqualified audit opinion. The current research is of applied type and has been carried out with a descriptive-correlation methodology and the research data has been collected using the statistical population including 134 companies listed to the Tehran Stock Exchange for the period of 2009 to 2019.We use multivariable binary logistic regression for data statistical analysis The results of this study show that the auditor's narcissism has a positive and significant relationship with the unqualified audit opinion. Also, the type of auditor and the percentage of shares owned by the major shareholder have a positive and significant relationship with the probability of issuing an unqualified audit opinion. If we assume that unqualified audit report is due to the acceptance of the amendments imposed by the auditor on client; This shows that the auditor's narcissism has a positive effect on audit quality.

The purpose of this study is to investigate the effect of reducing the supervisory mechanism on the relationship between auditors' unusual fees and fraud in financial statements. The current research is applied and from the methodological point of view, the correlation is causal type (post-event). The statistical population of the research is all the companies admitted to the Tehran Stock Exchange and using the systematic elimination sampling method, 90 companies were selected as the research sample and were examined in the 10-year period between 2012 and 2021. Finally, the final research hypotheses were tested using Logistic Regression and Eviuse software. The results of the research hypothesis test showed that there is a direct relationship between the auditor's unusual fees and fraud in the financial statements, and also the reduction of the supervisory mechanism (weakness of internal control) aggravates this relationship. The results of the research hypothesis test showed that there is a direct relationship between the auditor's unusual fees and fraud in the financial statements, and also the reduction of the supervisory mechanism (weakness of internal control) aggravates this relationship.

The purpose of this study is framework of auditors' analytical thinking patterns and its systematic drawing in the context of the current functions of the auditing profession. This study is considered to be exploratory and analytically mixed method. Because due to the lack of a coherent framework regarding auditors' analytical thinking patterns in judgment, this study identified the themes of the study through interviews and coding through thematic analysis. Then, using fuzzy Delphi analysis, the reliability of the identified dimensions was analyzed, and finally, in the quantitative part, systemic representation analysis was used to explain the identified organizing themes in the context of the current functions of the auditing profession. In this study, according to the theoretical saturation point in thematic analysis, 12 accounting and auditing experts participated, and in the quantitative part, 22 auditing partners with experience and specialized knowledge participated. The results of the study in the qualitative part during the 12 interviews conducted indicate the existence of 3 overarching themes, 6 organizing themes and 35 basic themes. On the other hand, the results of the system representation as a quantitative analysis showed that the critical thinking method is considered the most stimulating model of the auditors' analytical thinking, which can bring the result of the pragmatist analytical thinking method in the context of the professional auditing functions.

The purpose of this research is to investigate the association between the audit committee’s oversight of the internal audit function (IAF) and the nature of IAF activities. In this paper, it is assumed that regarding the role of the audit committee in preventing financial misstatements leads to an increase in the focus of IAF on internal controls. Based on the survey of 140 Chief Audit Executives (CAE) of Tehran Stock Exchange listed companies in 2020, research variables have been measured. A regression model is used to test the research hypothesis. Based on the opinions of CAEs participating in this research, the results show that the audit committee’s oversight of the internal audit function leads the IAF toward a more internal-controls-oriented focus. Also, the size of the company, financial leverage, ratio of inventories and the significant weakness in internal controls have a positive and significant effect on the IAF internal-controls-oriented focus. Finally, the results show that the sales growth rate and operating cash flow do not have a significant effect on the IAF internal-controls-oriented focus.
