Scholarcy highlights

  • The influence of demographic variables on cognitive test performance has proved crucial to the reliability and validity of clinical neuropsychology assessment, and screening for cognitive impairment relies heavily on the reliability of the available normative database with which to compare a client’s test performance
  • An initial treatment of the data investigated the influence of demographic variables, age, gender, and education on various measures derived from the TMT
  • A series of standard multiple regression analyses examined whether demographic variables significantly influenced performance on TMT-A and TMT-B and whether these variables affected the difference and ratio scores
  • In relation to the baseline measures of the TMT, the results of the present study support previous findings regarding the influence of demographic variables on performance of the TMT
  • Age accounted for a significant amount of variance in performance for both TMT-A and TMT-B in our healthy older adult sample
  • It would appear that the influence was limited to psychomotor speed, as only TMT-A performance was significantly predicted by gender
  • Given this finding we have provided normative data tables for all common clinical indices of the TMT, adjusting for age and education, for a large sample of healthy older adults
