Careless and inconsistent responding is a common issue with self- reported instruments, observed in approximately 10% of respondents. The purpose of this study was to develop an Inconsistency Responding Scale (IRS) for the Durand Adaptive Psychopathic Traits Question- naire (DAPTQ). First, a derivation sample (N = 525) was used to develop the IRS-DAPTQ, a scale generating a total score from the absolute difference of 12 pairs of items with high intra-correlation. Second, the validity of the IRS-DAPTQ was assessed using human (N = 943) and randomly generated (N = 1000) data. The IRS-DAPTQ successfully differentiated human data from randomly generated data. The IRS-DAPTQ scores showed a negative association with conscientiousness and had higher specificity for a sample of the gen- eral population recruited online than for a sample of undergraduate students. These findings support the usefulness of the IRS-DAPTQ for identifying individuals displaying an inconsistent responding style.
