Cybercrime-related attitudes among university students may reflect the interplay of personal morality, civic attachment, and social influence. This study examined the relationships among moral values, patriotism, peer pressure, and resistance to cybercrime-related attitudes among undergraduates in South-West Nigeria. A cross-sectional correlational design was adopted, and data were obtained from 347 undergraduates in tertiary institutions across Lagos, Ogun, and Oyo States using a multistage sampling procedure. The study examined the direct relationships among the variables, the indirect roles of patriotism and peer pressure, and the moderating role of gender. Moral values and patriotism were associated with greater resistance to cybercrime-related attitudes, whereas peer pressure was associated with lower resistance. Patriotism did not mediate the relationship between moral values and resistance, whereas peer pressure showed a significant indirect effect. Gender did not moderate the relationship between moral values and resistance. The findings indicate that resistance to cybercrime-related attitudes involves distinct but intersecting moral, civic, and interpersonal processes. The study contributes to cyberpsychological research by examining civic attachment alongside moral values and peer influence in understanding cybercrime-related attitudes among Nigerian undergraduates. The findings further suggest that university-based cybercrime prevention should combine moral and digital citizenship education with peer-norm interventions that challenge the social normalisation of cybercrime.
