Neuropsychologists' practice patterns in assessing premorbid intelligence.

The current study surveyed practicing neuropsychologists about the methods they use to estimate premorbid levels of function, and their prior training with these methods. Doctoral level psychologists, who are members of the National Academy of Neuropsychology, were sent a questionnaire developed by the authors to assess these variables. Findings suggest that there is relatively little use of strategies specifically designed to assess premorbid ability. Demographics and training were not associated with methods used. Over one third of the respondents indicated that they believed their formal training had not been adequate in helping them to address this issue.
