On the ecological validity of the behavioural assessment of dysexecutive syndrome measure in mild traumatic brain injury

Background A growing concern in neuropsychology is whether neuropsychological test measures (NTMs) can predict functional outcome (i.e. ecological validity). The relationship between neuropsychological tests and return to work (RTW) outcomes following mild traumatic brain injury (mTBI) found that the majority of tests were either weakly or completely unrelated. As such, many have opined that clinical neuropsychology should adopt new tests that relate test performance to real-world functioning, such as the Behavioural Assessment of Dysexecutive Syndrome (BADS). Further investigation into the BADS sensitivity to employment status in a mTBI sample is needed.
