The specific objectives were to: evaluate the effect of risk-based auditing on the fraud rate in the University of Calabar; examine the role of forensic auditing in reducing the fraud rate in the University of Calabar; assess the effectiveness of continuous auditing techniques in fraud rate in the University of Calabar; and determine the influence of data analytics on the fraud rate in the University of Calabar. The study adopted a survey research design. The population of this study comprised Bursary staff, totaling eight hundred and thirty (830). The study used simple random sampling and primary sources. The study presented the collected data in tables and percentages. This study used multiple regression analysis. The results revealed thus: there was a negative and significant effect of risk-based auditing on the fraud rate; there was a significant effect of forensic auditing in reducing the fraud rate; there was a positive significant effect of continuous auditing techniques in fraud rate; and there was a significant effect of data analytics on the fraud rate in University of Calabar. The study recommended that organizations should adopt advanced audit techniques such as data analytics and continuous auditing. Regulatory bodies should also enforce compliance with audit standards. Organizations should invest in technology to support modern audit practices.

KEYWORDS: Internal audit techniques, fraud rate, risk-based auditing, forensic auditing, fraud rate, continuous auditing techniques, data analytics.

INTRODUCTION

Fraud has emerged as one of the most persistent challenges confronting organizations across both developed and developing economies. It undermines financial integrity, erodes stakeholder confidence, and organizational sustainability. In Nigeria and other emerging economies, fraud has become particularly alarming because of weak internal controls, regulatory gaps, and increasingly sophisticated fraudulent schemes (Association of Certified Fraud Examiners, 2024). Organizations, especially in the financial sector, are continuously exposed to risks such as asset misappropriation, financial statement fraud, and cyber-related fraud. Internal auditing plays a critical role in mitigating fraud risks by providing independent assurance on the internal control systems. Internal audit techniques include systematic procedures and tools designed to evaluate organizational processes, ensure compliance, detect irregularities, and prevent fraud (Institute of Internal Auditors, 2023). These techniques include risk-based auditing, forensic auditing, continuous auditing, data analytics, and control testing. The relationship between internal audit techniques and fraud rate is therefore of significant academic and practical importance (Figure 1). Effective application of internal audit techniques is expected to reduce the occurrence and impact of fraud, while weak or outdated audit practices may allow fraud to thrive. This study examines how internal audit techniques influence fraud rates, with particular emphasis on their effectiveness in detecting, preventing, and deterring fraudulent activities.

Despite the growing emphasis on corporate governance and internal control systems, fraud remains pervasive across organizations. Reports indicate that organizations lose approximately 5% of their annual revenue to fraud globally (ACFE, 2024). In Nigeria, recurring cases of financial misappropriation, embezzlement, and insider fraud raise concerns about the effectiveness of internal audit mechanisms. One major issue is that many organizations still rely on traditional audit techniques that may not be sufficient to address modern, technology-driven fraud schemes. Additionally, internal auditors may lack the independence, technical expertise, or tools required to detect sophisticated fraud. Weak enforcement of audit recommendations further exacerbates the problem. Moreover, empirical findings remain inconsistent on whether internal audit techniques reduce fraud rates. While some studies suggest that advanced techniques such as forensic auditing and data analytics significantly reduce fraud, others argue that organizational culture and management override play a more dominant role. This gap necessitates a comprehensive examination of how specific internal audit techniques influence fraud rates, particularly in developing economies where institutional frameworks may be weaker.

LITERATURE REVIEW AND HYPOTHESIS DEVELOPMENT

Internal auditing has evolved significantly from its traditional watchdog role into a strategic function that adds value to organizational governance, risk management, and control processes. According to the Institute of Internal Auditors (IIA, 2023), internal auditing is defined as an independent, objective assurance and consulting activity designed to add value and improve an organization’s operations. It helps organizations accomplish their objectives by bringing a systematic, disciplined approach to evaluating and improving the effectiveness of risk management, control, and governance processes. Modern internal auditing goes beyond mere compliance checking to encompass risk-based evaluation, performance auditing, and advisory services. This shift reflects the increasing complexity of business environments and the need for proactive fraud prevention mechanisms (Eulerich et al., 2023). In this regard, internal auditors are expected to anticipate risks, identify vulnerabilities, and recommend corrective actions before fraud occurs.

Fig. 1 Conceptual framework

Risk-based auditing

Forensic auditing

Internal audit techniques refer to the tools, procedures, and methodologies internal auditors use to assess organizational operations and detect irregularities. Traditional techniques include transaction testing, vouching, compliance auditing, and physical verification. While these methods remain relevant, critics often describe them as reactive rather than proactive because they typically detect fraud after it occurs (Arens et al., 2020).

Risk-Based Auditing (RBA)

Risk-based auditing is a proactive approach that focuses audit efforts on areas with the highest risk exposure. It involves identifying, assessing, and prioritizing risks, followed by allocating audit resources accordingly (IIA, 2023). RBA enhances efficiency and effectiveness by ensuring that critical risk areas receive adequate attention. Scholars argue that RBA significantly reduces fraud opportunities by strengthening controls in vulnerable areas (Beck, 2023). However, its effectiveness depends on accurate risk assessment and organizational transparency.

Forensic Auditing

Forensic auditing is a specialized field that combines accounting, auditing, and investigative skills to examine financial information for use in legal proceedings. It focuses on detecting, investigating, and preventing fraud through detailed examination and evidence gathering (Singleton & Singleton, 2010). Forensic auditing techniques include data mining, digital forensics, lifestyle analysis, and fraud risk assessment. These techniques are particularly effective in uncovering complex fraud schemes that may not be detected through conventional auditing.

Continuous Auditing

Continuous auditing uses automated tools to perform audit activities in real time or near real time. It allows for ongoing monitoring of transactions and controls, thereby reducing the time lag between fraud occurrence and detection (Vasarhelyi et al., 2012). Continuous auditing is increasingly relevant in digital environments where transactions occur rapidly and in large volumes. It enhances fraud detection by identifying anomalies as they occur.

Data Analytics in Auditing

Data analytics has emerged as a transformative tool in internal auditing. It involves the use of statistical techniques, algorithms, and software to analyze large datasets and identify patterns, trends, and anomalies (Vasarhelyi, et al., 2012). Audit data analytics improves fraud detection by enabling auditors to examine entire transaction populations rather than relying on sampling. This increases the likelihood of identifying irregularities and reduces audit risk.

Fraud rate

Fraud is defined as any intentional act of deception designed to secure unfair or unlawful gain (ACFE, 2024). It encompasses various forms, including asset misappropriation, corruption, and financial statement fraud. Fraud rate refers to the frequency or incidence of fraud within an organization over a specified period. Researchers often measure it using indicators such as the number of reported fraud cases, financial losses incurred, or the frequency of control breaches. The increasing prevalence of fraud in organizations has been attributed to factors such as weak internal controls, poor corporate governance, economic pressures, and technological advancements (Dorminey et al., 2012).

Internal Audit and fraud prevention

Internal auditing plays a central role in fraud prevention by establishing and maintaining effective internal control systems. According to COSO (Committee of Sponsoring Organizations, 2013), internal control consists of five components: control environment, risk assessment, control activities, information and communication, and monitoring. Internal auditors contribute to fraud prevention by: Evaluating the effectiveness of internal controls, identifying weaknesses and recommending improvements, conducting fraud risk assessments, and promoting ethical behavior and compliance. Research suggests that organizations with strong internal audit functions experience lower fraud rates due to improved oversight and accountability (Bonrath & Eulerich, 2024). Fraud detection involves identifying fraudulent activities after they have occurred. Internal audit techniques such as forensic auditing, data analytics, and surprise audits are particularly effective in detecting fraud. Detection is enhanced by advanced technologies, Continuous monitoring systems, and Whistleblowing mechanisms. However, detection alone is not sufficient; organizations must also focus on prevention to minimize losses. The effectiveness of internal audit in reducing fraud depends largely on its independence and objectivity. Internal auditors must be free from management interference to perform their duties effectively (IIA, 2023). Lack of independence can compromise audit findings and allow fraud to persist. Therefore, organizational structures should ensure that internal auditors report to audit committees rather than management (The Institute of Internal Auditors, 2024).

Internal Audit Techniques and Fraud Rate

The relationship between internal audit techniques and fraud rate is generally inverse. Olowokudejo et al. (2023), in their study of deposit money banks in Nigeria, employed a survey research design and regression analysis to examine the effectiveness of risk-based auditing. Their findings revealed a statistically significant inverse relationship between risk-based auditing and fraud rate. Specifically, banks that prioritized high-risk areas through structured risk assessment frameworks experienced fewer fraud incidents. The study also highlighted that risk-based auditing improves resource allocation efficiency within audit departments, thereby strengthening fraud detection capabilities.

Similarly, Adeyemi and Adeniyi (2024) empirically investigated the role of forensic auditing in mitigating fraud within Nigerian public sector institutions. Using a mixed-method approach combining questionnaire data and case analysis, the study found that forensic auditing techniques—such as digital forensics, financial profiling, and investigative interviewing—significantly reduced fraud occurrence. The authors concluded that forensic auditing not only detects fraud but also deters it by increasing employees' perceived likelihood of detection.

In a related study, Okafor et al. (2022) examined the impact of continuous auditing on fraud prevention in selected manufacturing firms. Using panel data analysis, the study showed that organizations adopting continuous auditing systems experienced a notable decline in fraud rates. The real-time nature of continuous auditing enables prompt identification of anomalies, thereby reducing the window of opportunity for fraudulent activities. However, the study also noted that the effectiveness of continuous auditing depends on the availability of technological infrastructure and skilled personnel.

Kumar and Gupta (2024) explored the role of data analytics in fraud detection within financial institutions in India. Their study employed a quantitative approach using structural equation modeling (SEM) to analyze data collected from audit professionals. The findings indicated that data analytics significantly improves fraud detection accuracy by identifying unusual transaction patterns and outliers. The study emphasized that data-driven audit techniques outperform traditional audit methods in detecting complex and concealed fraud schemes.

Eze (2023) focused on internal control evaluation as a core internal audit technique in Nigerian manufacturing firms. Using correlation and regression analysis, the study found that effective internal control systems are negatively correlated with fraud occurrence. Organizations with strong control environments, regular control testing, and compliance monitoring reported lower fraud rates. The study reinforced the importance of control-based auditing as a foundational tool in fraud prevention.

Expanding beyond Nigeria, Hazaea et al. (2023) investigated the effectiveness of internal audit practices in reducing fraud in Middle Eastern financial institutions. Their findings showed that internal audit independence and the use of advanced audit tools significantly reduce fraud risk. The study also highlighted that organizational support and management commitment are critical factors influencing the effectiveness of internal audit functions.

In South Africa, Mbetha and Moosa (2024) examined the relationship between internal audit quality and fraud detection in public enterprises. The study found that audit quality—measured by auditor competence, independence, and adherence to standards—significantly reduces fraud rates. High-quality internal audit functions were associated with improved fraud detection and reduced financial irregularities.

A study by Chen and Wu (2023). in China investigated the role of technology-enabled auditing in fraud prevention. Using a large dataset from listed companies, the study found that firms utilizing artificial intelligence (AI) and machine learning tools in auditing reported significantly lower fraud incidences. The authors argued that technological integration enhances the predictive and preventive capabilities of internal audit systems.

Furthermore, Musa and Ibrahim (2023) examined the constraints affecting internal audit effectiveness in Nigeria. Their findings revealed that despite the adoption of modern audit techniques, factors such as lack of independence, inadequate funding, and management interference limit internal audit effectiveness in fraud control. This suggests that the mere presence of audit techniques is insufficient; institutional support and governance structures are equally important.

A recent study by Shehu (2025) analyzed the combined effect of multiple internal audit techniques on fraud rate in Nigerian SMEs. Using multiple regression analysis, the study found that combining risk-based auditing, forensic auditing, and data analytics produced a greater reduction in fraud rate than using a single technique. This supports the contingency theory perspective that a multi-faceted approach is more effective in addressing fraud.

In addition, Mbetha and Moosa (2024). investigated the impact of internal audit reporting mechanisms on fraud control. Their findings indicated that timely, transparent reporting improves management response to audit findings, thereby reducing fraud risk. Delays in implementing audit recommendations were found to increase the likelihood of repeated fraudulent activities. From a global perspective, the Association of Certified Fraud Examiners (ACFE, 2024) reported that organizations with proactive internal audit functions detected fraud faster and incurred lower losses compared to those without such systems. The report emphasized that internal audit techniques such as data monitoring, surprise audits, and whistleblowing mechanisms significantly contribute to fraud reduction. Despite these positive findings, some studies present contrasting evidence.

For instance, Olaoye and Adekola (2017). found that internal audit techniques had a limited impact on fraud reduction in organizations with weak corporate governance structures. The study argued that management override of controls often neutralizes the effectiveness of audit procedures. Similarly, Tagang et al. (2024) reported that while data analytics improves fraud detection, its effectiveness is limited by data quality issues and lack of technical expertise among auditors. This highlights the need for capacity building and data governance frameworks. Overall, the empirical literature suggests a strong inverse relationship between internal audit techniques and fraud rate. However, contextual factors such as organizational culture, technological capability, the regulatory environment, and auditor independence influence the effectiveness of these techniques. The literature also indicates a shift from traditional audit methods to more proactive and technology-driven approaches. Based on the review of the literature, the following hypotheses were formulated:

H01: There is no significant effect of risk-based auditing on the fraud rate in the University of Calabar;

H02: There is no significant effect of forensic auditing on reducing the fraud rate in the University of Calabar;

H03: There is no significant effect of continuous auditing techniques on the fraud rate in the University of Calabar;

H04: There is no significant effect of data analytics on fraud rate in the University of Calabar.

Theoretical framework

This study is anchored on several relevant theories that explain fraud occurrence and the role of internal audit.

The Fraud Triangle Theory, developed by Cressey (1953), posits that fraud occurs when three elements are present: pressure, opportunity, and rationalization. Internal audit techniques primarily target the “opportunity” element by strengthening controls and reducing loopholes. The fraud triangle model emerged from observation. Cressey (1953) studied the behavior of 250 criminals serving jail sentences in a United States Cell. Cressey (1953) observed a common characteristic among the inmates and concluded that they engaged in payroll fraud because of unshareable financial problems, opportunities to defraud due to internal control weaknesses, and the ability to defend their criminal actions after committing the crime. Based on these observations, Cressey (1953) hypothesized that three factors must be present for individuals to commit fraud. These factors are pressure, opportunity, and rationalization. According to this theory, “whether the fraud benefited the perpetrator directly or one that benefited a perpetrator’s organization, the three conditions for fraud were always present for fraud to occur”. Consequently, these three factors became the pillars of the fraud triangle theory.

METHODOLOGY

The study adopted a survey research design. The study focused on internal audit techniques and the fraud rate at the University of Calabar. The study population consisted of University of Calabar staff. The study population comprised University staff. The population of this study comprised staff of the Bursary unit (450), Internal Audit (55), Stores (20), Procurement (15), Works (250), Budget (25), and Payroll (15). A total of eight hundred and thirty (830). The study used simple random sampling and primary sources. Taro Yamane formula was used to determine the sample size. The formular is stated thus:

\(\frac{N}{1 + N(e)²}\)

Where

N = Population

1 = Constant

E = tolerable error (0.05)

\[\frac{N}{1 + N(e)²}\]

= \(\frac{830}{1 + 830(0.05)²}\)

= \(\frac{830}{1 + 830(0.0025)}\)

= \(\frac{830}{1 + 2.075}\)

= \(\frac{830}{1.075}\) = 269 \(\cong\) 270

The sample size is two hundred and seventy (270). Of the 270 copies distributed, 265 were correctly filled and returned. The collected data were presented in tables and percentages. This study used multiple regression analysis. For the purpose of this study, the empirical model for this study is specified thus;

The econometric model is stated thus:

FR = b₀ + b₁RBA + b₂FA+ b₃CAT + b₄DA+ Ut _{-----------------------------1}

Where

FR = Fraud rate (measured as the proportion of fraudulent activities)

Internal audit techniques (measured with Risk-based Auditing, Forensic Auditing, Continuous Auditing Techniques, Data analytics)

RBA = Risk-based Auditing

FA = Forensic Auditing

CAT = Continuous Auditing Techniques

DA = Data analytics

From Table 1, the mean values of RBA analysis (17.8585), FA (17.2219), CAT (18.0514), DA (18.5305), and FR (17.0965). The standard deviations of RBA (1.56553), FA (1.37921), CAT (1.69551), DA (1.49565), and FR (1.49095). To assess the relationships among the variables used in this study, the researcher used the Pearson Product-Moment Correlation. The correlations among the variables are presented in Table 2. The results indicated that selected variables were significant at the 1% level, while others were significant at the 5% level. A normality test was conducted to determine whether the dataset followed a normal distribution. Regression analysis requires normally distributed data, with skewness and kurtosis values close to zero. Table 3 presents the normality test results, including computed skewness and kurtosis values for all variables in the study. The results indicated that all variables met the normality condition, as their skewness and kurtosis values fell between -2 and +2 for skewness and -7 and +7 for kurtosis, which are considered acceptable ranges.

Risk-based auditing has positive significant effect on the fraud rate at the University of Calabar. Internal auditing has evolved significantly from its traditional watchdog role into a strategic function that adds value to organizational governance, risk management, and control processes. It helps organizations accomplish their objectives by bringing a systematic, disciplined approach to evaluating and improving the effectiveness of risk management, control, and governance processes. However, effectiveness of internal audit techniques depends on factors such as auditor independence, organizational support, and technological capability. Internal audit techniques play a critical role in reducing fraud rates within organizations.
