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.

Methods of estimating premorbid functioning.

Clinical neuropsychological assessment frequently requires the comparison of obtained scores against some estimate of premorbid level of functioning, but only recently has significant attention been turned to objective methods to accomplish this objective. Clinical judgment, although useful in some circumstances, is generally insufficient. Other methods of estimating premorbid function include demographic regression formulae, such as the Barona formula, subtest scatter methods, such as that suggested by Lezak, and the use of current scores on tests of presumably spared abilities, such as the National Adult Reading Test (NART).

Use of Wisconsin Card Sorting Test short forms with school-age children.

Short forms of the Wisconsin Card Sorting Test (WCST) have been developed and studied in adult populations, however studies addressing their use in children are lacking. This study compared the full WCST to two short forms in a sample of 174 school-age children who were referred for neuropsychological evaluation. Multiple regression was used to predict standard scores (SSs) on the full WCST.

Presence of post-concussion syndrome symptoms in patients with chronic pain vs mild traumatic brain injury.

Primary Objective: Post-concussion syndrome (PCS) is a controversial diagnosis, in part because many symptoms may be present in other conditions, such as chronic pain (CP). However, direct comparisons between people with CP and mild traumatic brain injury (MTBI) are limited. The purpose of this study was to compare people with CP and MTBI on a measure of PCS symptoms.
