Abstract
Objective: With the proliferation of telehealth and online neuropsychological assessment, a question is raised to whether the results of such measures are comparable to those used in person. Thus, this study aimed to compare the performance of an online adaptation of the Portland Digit Recognition Test (PDRT) at detecting simulators of traumatic brain injury (TBI) to that of the in-person PDRT when TBI patients are utilized.
Methods: 400 participants were randomly assigned to the simulated malingerers’ or the control group and completed an online adaptation of the PDRT. The malingerers’ group was instructed to perform as if they have a TBI. Sensitivity and specificity using the suggest cutoff score for the online PDRT were compared to in-person PDRT scores from published studies using the original suggested cutoffs.
Results: ROC analysis of online PDRT scores used during this study demonstrated a sensitivity of 94% and specificity of 95%. When compared to in-person studies that used samples of TBI patients (e.g. Greve and Bianchini, 2006; Greve et al., 2008; Bianchini et al., 2001), the online version of the PDRT consistently had higher sensitivity but not higher specificity.
Conclusions: This study has helped demonstrate the validity of an online version of the PDRT for detection of malingering. When compared to the sensitivity and specificity of in-person PDRT scores, the online version consistently had higher sensitivity and lower specificity. Additional research and comparisons are needed to further validate the online version of the PDRT for malingering detection.
