The journey is just as important as the destination—Digital neuropsychological assessment provides performance stability measures in patients with acquired brain injury
Fig 1
The development of the performance stability measures.
The development (in this example the Stroop, condition 3) is illustrated for one patient in four steps: (1) The “time between responses” (in seconds) is depicted on the vertical axis, with the orange dots reflecting the time between responses for one patient. The words (100 words in total) are depicted on the horizontal axis. The blue line is the average time of the healthy controls (n = 91) with a 95%CI (light blue shade); (2) In the Stroop, we computed 10 time bins of 10 words each. The standard error was calculated per time bin; (3) Here, the 10 time bins are depicted on the horizontal axis, and the standard error on the vertical axis. The orange line represents the standard error per time bin for one patient. (4) The number of time bins in which the standard error of a patient fell above normal range (e.g., 7 out of 10 bins) was computed into a proportion score (e.g., .7).
