Nelson,L., & Do, T. Using the MMPI-2 in Patients with Multiple Sclerosis.
This is a first-everstudy applyingGass’ neurocorrectionprocedureto the MMPI-2 in a sampleof patientswith MultipleSclerosis.Fifty subjectsparticipatedin this study.Conditions included Chronic-Progressiveand Relapsing-Remitting.Other tests were used as criterionmeasuresagainstwhichresultsbasedon the standardand neurocorrectedversionof theMMPI-2werecompared.ThesetestsincludedtheNeuropsychologyBehaviorandAffect Profile,designedto be completedby a relativerespondentaboutthe patient,and a modified version of the MMPI-2 DepressionScale, designed to be also completedby a relative respondent.Resultssupportedconcurrentvalidityof the MMPI-2DepressionScale, across both patient and relative respondents.Results further demonstratedsignificantdecreases acrossthreemajorMMPI-2Scales(Scales2, 7, and 8) in termsof T-scoreswhenthe testwas neurocorrectedusingGass’procedure.Neurocorrectedresultswerewithinnormallimits.Age effectswere also examined,supportingdecreaseddepressionin older subjects.The importance of consideringa neurocorrectionapproachin populationswhere neurologicalconditions includehigh base rates of physicalsymptomswas stressed.In these cases, using the MMPI-2may producefalse-positiveindicationsof pathologicalemotionalfunctioning. Nelson,L., Satz, P., Drebing,C., & Uchiyama,C. Personali@ Change Following Head Trauma: A Test Validity Study.
This studyrepresentsthe first attemptto cross-validateand report on the Neuropsychology BehaviorandAffectProfile(NBAP)usingclosedhead injury(CHI)participants.TheNBAP is designedto measureemotionalfunctioningbeforeand followinga brain event.Two CHI samples, differing primarily by method of ascertainment,were compared to a group of normal controls. Results provided support for concurrentand predictivevalidity of this measure of emotional functioningacross both CHI samples. A relatively new finding emergedwhich suggestedsignificantlyhigherlevelsof premorbidemotionalfunctioningin clinic-referredCHI patients comparedto CHI individualsnot seeking treatment (strictly researchparticipants).The possibilityof exaggeratedemotionallevelsin CHI clinicpatients was raised. Ogden,M. L., Lacritz,L. H., & Cullum,C. M. Qualitative Assessment of Semantic and Phonemic Fluency in Aging and Dementia.
Clinicalinterpretationof verbalfluencyperformancehas typicallyrelied more on quantitative than qualitativeanalyses,using total number of words generatedin a specifiedtime intervalto evaluatepatients’performances.This studyexaminedthe trends and diagnostic utilityof a qualitativescoringtechniquefor semantic(Animal)and phonemic(FAS)fluency tasksin patientswithAlzheimer’sDisease(AD;N = 82) and Parkinson’sDisease(PD;N = 64), as well as in a group of healthy elderly controls (ENC; N = 65). The groups were comparedon three componentsof generativenamingas originallydefinedby Troyeret al. (1997):(1) numberof wordsproduced,(2) clustering(i.e., ratio of wordsgeneratedwithin subcategories),and (3) switching(i.e.,frequencyof shiftsbetweenclusters).In termsof total number of words produced,controlswere superiorto the patient groups on both fluency
