Background: The accurate assessment of cognitive ability requires valid data, particularly among older adults. Non-credible performance, or symptom exaggeration, threatens the validity of neuropsychological assessments in Indonesia.
Purpose: This study aims to examine the diagnostic accuracy of four Performance Validity Tests (PVTs) by comparing healthy older adults and individuals simulating cognitive impairment.
Method: An experimental two-group design was used (N=25). Participants passed rigorous cognitive screening (MoCA > 26) and were randomly assigned to a control (n=12) or experimental (n=13) group. PVTs included NV-MSVT, TMJPI, CIHT, and embedded TMT measures.
Findings: Mann-Whitney U tests showed significant differences (p< .05) between groups, with controls outperforming simulators.

AUC values ranged from .713 to .907, indicating good to excellent accuracy in distinguishing the groups.
Implication: These findings establish a robust empirical foundation for more ethical and valid neuropsychological research in Indonesia, providing culturally relevant cut-offs to mitigate misdiagnosis in clinical practice, advance cross-cultural neuropsychology in Asia, and strengthen administrative and forensic decision-making.
