   We car­ried out a sim­i­lar study: Cog­ni­tive and Per­son­al­ity Deter­mi­nants of Post-injury Dri­ving Fit­ness (M. Som­mer et al 2010)
   Pub­lished in Clin­i­cal Neu­ropsy­chol­ogy (Oxford Jour­nals)
   Abstract
   Increas­ingly often, prac­ti­tion­ers in neu­ropsy­cho­log­i­cal reha­bil­i­ta­tion cen­ters are called upon to assess patients’ fit­ness to drive after brain
   injury. There is, there­fore, a need for valid and reli­able psy­cho­me­t­ric test bat­ter­ies that enable unsafe dri­vers to be iden­ti­fied. This arti­cle
   inves­ti­gates the con­tri­bu­tion of five driving-related per­son­al­ity traits to the pre­dic­tion of fit­ness to drive in patients suf­fer­ing from trau­matic
   brain injuries (TBI) or strokes over and above cog­ni­tive abil­ity traits that have already shown to be related to safe dri­ving. A total of 178
   patients suf­fer­ing from either strokes or TBI par­tic­i­pated in this study. All the par­tic­i­pants com­pleted a stan­dard­ized psy­cho­me­t­ric test
   bat­tery and sub­se­quently took a stan­dard­ized dri­ving test. The con­tri­bu­tion of the driving-related abil­ity and per­son­al­ity traits to the pre­dic­tion
   of fit­ness to drive was inves­ti­gated by means of a logis­tic regres­sion analy­sis and an arti­fi­cial neural net­work. The results indi­cate that
   both cog­ni­tive abil­ity and per­son­al­ity fac­tors are impor­tant in pre­dict­ing fit­ness to drive, although cog­ni­tive abil­ity fac­tors con­tribute slightly
   more to the pre­dic­tion of patients’ actual fit­ness to drive than per­son­al­ity fac­tors. Fur­ther­more, even though there are sub­tle dif­fer­ences in the
   pre­dic­tive mod­els obtained for the two sub­sam­ples (stroke and TBI patients), these dif­fer­ences are ade­quately accounted for by a more uni­tary
   model cal­cu­lated by means of an arti­fi­cial neural net­work that is capa­ble of tak­ing account of mod­er­at­ing effects between the pre­dic­tor
   variables.

   Thanks for shar­ing Fritz: Very inter­est­ing study!
