The accuracy of performance validity tests (PVTs) with culturally diverse populations has increasingly been questioned. High false positive rates have been found in some PVTs in culturally and linguistically diverse individuals within the U.S. and internationally. No study to date has investigated the accuracy of PVTs with Chinese-speaking immigrants (CSI) in the U.S. The current study aimed to evaluate two PVTs, the Test of Memory Malingering (TOMM) and Dot Counting Test (DCT), to determine their accuracy in a community sample of CSI with limited English proficiency. These two measures were used in a simulation design, contrasting 52 participants who were instructed to respond honestly to 22 participants instructed to feign incompetency to stand trial. Results demonstrated the scores of TOMM Trial 1 and Trial 2 were effective in classifying honest responders from simulators, whereas the DCT E-score did not differentiate the groups better than chance. However, false positive rates for the TOMM Trial 1, Trial 2, and the DCT E-score were relatively low. Only one honest responder (1.9%) was classified as exerting insufficient effort in TOMM Trial 1 and DCT E-score, and the TOMM Trial 2 did not misclassify any honest responders. Implications and cautionary statements are provided and discussed.
