This brief report sought to evaluate the classification statistics of the Advanced Clinical Solutions (ACS) embedded measures of symptom validity in relation to the Word Memory Test (WMT), a well-established standalone measure of effort in a sample of active duty military service members with a history of mild traumatic brain injury. Results demonstrated that relative to the WMT, the ACS embedded measures had adequate specificity, but lacked sensitivity. This result is in agreement with previous studies demonstrating poor sensitivity for embedded effort measures relative to standalone Symptom Validity Tests.
