Abstract :

Keywords: Minor head injury; Concussion; Forensic neuropsychology; Assessment; Malingering Abstract The identification and management of persistent post-concussion symptoms (PPCS) is reliant on the accurate and valid reporting of symptoms. To assist with the evaluation of validity, symptom validity indicators (SVIs) are used. This study explored the utility of the newly developed modified Rivermead Post-concussion Symptoms Questionnaire (RPQ), which embeds an SVI into the RPQ (mRPQ). Ninety-four participants completed the mRPQ two existing SVIs (the Validity-10 [Val-10] and the Mild Brain Injury Atypical Symptoms [mBIAS] scale) two performance validity tests (the Test of Memory Malingering [TOMM] and Warrington's Memory Recognition Test [WMRT]) and, a post-experimental questionnaire. This study utilized a simulation design, with participants randomly allocated to one of two conditions: mTBI Simulator (MS, n=47) or Biased mTBI Simulator (BMS, n=47). The BMS group received an additional biasing instruction to motivate distorted responding for a forensic assessment context. The validity measures were highly intercorrelated, as were the PPCS scores (p Author Affiliation: (1) School of Psychology and Counselling, Faculty of Health, Queensland University of Technology, Kelvin Grove Campus, O Block B Wing Victoria Park Road, Kelvin Grove, 4059, Brisbane, Australia (2) Australian Centre for Health Law Research, Queensland University of Technology, Brisbane, Australia (3) School of Psychology and Counselling, Queensland University of Technology, Brisbane, Australia (a) Article History: Registration Date: 07/01/2021 Received Date: 04/09/2021 Accepted Date: 06/30/2021 Online Date: 07/17/2021 Byline:
