Role of quality determinants of the internal audit function in corporate governance effectiveness. Senior management support as moderator: Evidence from Yemeni commercial banks

The purpose of this study was to determine if senior management support (SMSI) in
Yemeni commercial banks mediates the association between internal audit function
(IAF) quality characteristics and improved corporate governance effectiveness (CGE).
Internal auditors, heads of internal audit, chairmen and participants in audit committees, CEOs, and financial management of Yemeni commercial banks were given a list of
questions to answer. 158 full lists were obtained to evaluate after distributing the survey.
For data analysis and hypothesis testing in this work, Smart PLS 3 was used. The study
findings demonstrate a substantial relationship between CGE and IAF competence
and due professional care (CPCI), IAF independence and objectivity (INOI), and IAF
professional ethics (PEI). The outcomes of the study also demonstrate that there is no
relationship between CGE and chief audit executive (CAE) Leadership Style (CLS). In
terms of the moderate variable’s influence, the findings revealed that SMSI positively
changes the link between CLS, CPCI, and corporate governance effectiveness. SMSI,
on the other hand, has no influence on the link between INOI, PEI, and the efficacy
of corporate governance. The findings add to the knowledge on IAF factors affecting
the efficacy of CG and the role of SMSI in changing this relationship in developing
countries such as Yemen.
