ANDERSON & B. BANWELL. Neuropsychological Functioning inPediatric Multiple Sclerosis: Preliminary Findings of a ProspectiveInvestigation.Multiple sclerosis (MS) is a relatively rare demyelinating disease, withapproximately 3.5–7.50100,000 persons newly diagnosed with MS eachyear. Pediatric MS is much rarer, as only 3–5% of total diagnoses are madeat 16 years of age or younger. Adult onset MS has been well-studied andsignificant neuropsychological deficits have been documented (e.g., Rao,Leo, Bernardin & Unverzagt, 1991), while the available literature on pe-diatric MS consists of case reports and retrospective case series. In ourprospective investigation, children and adolescents (n 5 10; 9–17 years ofage) with clinically definite MS (time since diagnosis ranging from 2months to 4 years, 9 months) completed a comprehensive neuropsycho-logical battery. Relative to normative samples, the MS group performedsignificantly poorer on some indices from a measure of psychometricintelligence (FSIQ, VIQ, PIQ, VCI), visual motor integration, visual learn-ing and memory, story recall, and spelling. Though these findings aremore widespread than those typically reported in the adult literature, theweaknesses noted are consistent with adult findings. The influence of timesince diagnosis was also explored (, 2 years, n 5 6; . 2 years, n 5 4!.Participants with a longer time since diagnosis performed significantlyworse on some indices from a measure of psychometric intelligence (FSIQ,PIQ, POI), visual perception0construction, reading comprehension, andapplied mathematical knowledge. These findings are more consistent withthose reported in the adult literature, with a clear deficit in visual-spatialprocessing in the face of relatively preserved verbal functioning found forthose participants with a longer time since diagnosis.Correspondence: Peter Anderson, Department of Psychology, Hospital forSick Children, 555 University Avenue, Toronto, Ontario, M5G 1X8 Can-ada. peter.anderson@sickkids.caPoster Session 5/12:00–2:30 p.m.CROSS CULTURALR. CHAN, I. ROBERTSON, & T. MANLY. Cross-Cultural Validationof the Test of Everyday Test of Attention With Confirmatory FactorAnalysis.The Test of Everyday Attention (TEA) was developed in improve uponexisting methods of assessing attentional problems in clinical practice. Itconsists of 8 subtests measuring sustained, selective, and divided atten-tion. Its construction was also designed to mimic everyday activities. How-ever, the construct validity of the TEA has not been fully studied with amore stringent methodology. This study aimed to examine the constructvalidity and its stability across cultures with confirmatory factor analysis(CFA). A sample of 148 healthy UK and 133 Hong Kong Chinese partici-pants were recruited. They were well-matched with gender proportion andeducational level. Three models were tested in the present study: (1) theone from the original proposed underlying attentional contructs (VisualSelection, Sustained Attention, and Switching) (Robertson et al., 1996);(2) the discovered 4-factor structure by exploratory factor analysis (Rob-ertson et al., 1996); and (3) the discovered 4-factor structure by explor-atory factor analysis (Chan et al., 1999). The CFA solutions suggested thatthe 3-factor model provided the best fit for both samples (AGFI 5 0.83,GFI 5 0.91, CFI 5 0.91 for UK sample; AGFI 5 0.85, GFI 5 0.93, andCFI 5 0.90 for HK sample). A direct comparison of chi-squares furtherindicate significant differences among the 3-factor models and the alter-native models ~x2 5 6.54, p 5 0.075 for UK sample, and x2 5 25.3, p 50.001 for HK sample). Therefore, the 3-factor model provides the best fitof attentional components embedded in the TEA and it is consistent andstable across cultures.Correspondence: Raymond Chan, Department of Psychiatry, University ofHong Kong, Pokfulam Road, Hong Kong, China. rckchan@hkucc.hku.hkR.

Verbal Fluency Norms in a Community Population in HongKong.Category fluency tests are important cognitive and clinical neuropsycho-logical assessments, particularly for patients with frontotemporal impair-ments like in schizophrenia and dementia. The lack of local Hong KongChinese norms together with the growth in the number of Hong Kongimmigrants to North America, Canada, and Australia, have increased theneed for well-validated normative data for Hong Kong Chinese. This studyaimed to provide normative data for healthy Cantonese-speaking HongKong Chinese, ranging in age from 16 to 65, on 4 commonly used mea-sures of category fluency—“animal,” “means of transport,” “food,” and“furniture.” A total number of 100 healthy subjects (42 male and 58 fe-males) were recruited in the community. The mean age and educationallevel of the sample was 32 (SD 5 11.76! and 11.31 years (SD 5 3.64!,respectively. The findings indicate that the category “food” and “animal”had the highest mean number of citations (mean 5 21.52, SD 5 7.14 forfood; mean 5 20.07, SD 5 5.84 for animal), whereas the category “furni-ture” and “means of transport” had the lowest mean score (mean 5 14.24,SD 5 4.79 for furniture; mean 5 15, SD 5 3.86 for means of transport).Rankings of frequently cited individual items within each category werealso presented. The implication of applying this western driven measure inHong Kong Chinese and psychiatry research is discussed.Correspondence: Raymond Chan, Department of Psychiatry, the Uni-versity of Hong Kong, Pokfulam Road, Hong Kong, China. rckchan@hkucc.hku.hkL. WALKER, A. SMITH, S. KINNEY, & J. TIBBS. Neuropsycholog-ical Norms for African-Americans.Neuropsychological tests are commonly used to evaluate deficits associ-ated with traumatic brain injury (TBI). TBI produces a variety of cogni-tive and behavioral deficits that can be identified through neuropsychologicaltests, which can assist in the development of specific rehabilitative strat-egies that may facilitate the patient’s ability to function better both occu-pationally and socially. Studies have shown that individuals of lowersocioeconomic status (SES) have a greater likelihood of sustaining a TBI.Further, African-Americans tend to be over-represented at the lower endof the SES. One long-standing issue with standardized testing has been thelack of adequate normative test data for non-European-Americans. Cross-cultural and psychometric psychologists suggest that one method for pro-viding adequate clinical evaluation is to develop separate normative datafor different racial groups as is often done with other demographic factors(i.e., age, gender, etc.). In the current preliminary study, 20 African-American, orthopedic patients were recruited from an acute care orthope-dic hospital unit. Patients with a history of drug0alcohol abuse, psychiatricdisturbance, or neurological illness were not included in the study. Cog-nitive measures were administered 2 to 5 days post-injury involving ori-entation, attention, concentration, speech and language, perceptualprocesses, memory, new learning, and executive functions. Preliminaryresults indicate that African-American participants performed below nor-mative means on some subtests of the Wechsler’s Adult Intelligence Scale–Third Edition (WAIS–III) and at the normative mean on other WAIS–IIIsubtests. A similar pattern was observed on neuropsychological measures.Correspondence: Ayanay Smith, Morehouse College, Department of Psy-chology, 830 Westview Drive, Atlanta, GA 30314. ayanay0616@aol.comE.
