The purpose of this study is to examine the auditor's dysfunctional behavior mediating the influence of Machiavellian characteristic and time budget pressure on audit behavior.

Determination of the sample was accomplished based on the nonprobability sampling method with saturated sample technique. The research sample was 94 auditors and questionnaires were distributed among them and managed to collect 65 questionnaires. Data analysis was performed using the path analysis model. The results show the auditor's dysfunctional behavior fully mediated the influence of Machiavellian traits on audit quality, while the auditor's dysfunctional behavior mediated the partial effect of time budget pressure on audit quality. The results of this study can be considered for auditors and input for IAPI in improving audit quality by suppressing and avoiding the auditor's dysfunctional behavior due to the influence of Machiavellian characteristic and time budget pressure.
