Abstract:
This study examines the role of
internal control systems in preventing fraud in public
finance, using the Ministry of Finance (MoF) of Afghanistan
as a case study. It aims to assess how the five components of
internal control such Environment, Risk Assessment, Control
Activities, Information and Communication, and Monitoring
Activities influence fraud prevention within public sector
financial management. The research adopted a case study
design and a deductive approach. A stratified random sampling
technique was used to select 354 employees from various
departments within the Afghanistan Ministry of Finance.
Primary data was collected through structured questionnaires,
and the data was analyzed using descriptive statistics and
multiple regression analysis to test the relationship between
internal control components and fraud prevention.
The
findings reveal that internal control systems collectively
have a significant effect on fraud prevention in public
finance. Among the five components, Control Activities
demonstrated the strongest influence (t = 5.516), indicating
that well-defined policies, approval hierarchies, and
segregation of duties are the most critical factors in
reducing fraudulent practices. The other components—Control
Environment, Risk Assessment, Information and Communication,
and Monitoring Activities—also showed positive but
comparatively lower effects. The regression model was
significant (F = 9.602, p < 0.05), with an adjusted R² of
0.621, indicating that 62% of the variation in fraud
prevention is explained by the five internal control
components. Descriptive analysis further revealed that while
employees acknowledged the importance of internal controls, a
significant proportion expressed uncertainty about their
practical effectiveness, highlighting gaps between formal
policies and actual implementation. The study underscores the
need for the Ministry of Finance to strengthen the practical
implementation of internal controls, particularly by
reinforcing segregation of duties, enhancing internal audit
functions, institutionalizing structured risk assessment
processes, and improving communication and training on fraud
awareness. Management commitment and a transparent
organizational culture are essential to translating formal
controls into effective fraud prevention.
