| The purpose of the study is to investigate accuracy of the Arnold et al. Finger Tapping cut-offs in a new, large sample of "real world" credible and non-credible male and female patients. The purpose of the research is to cross-validate cut-offs for use of the Finger Tapping Test as a performance validity measure. The original cut-offs were published by Arnold et al. (2005) and it is important to cross-validate cut-offs on new populations to show that specificity/sensitivity data are stable and replicable. The data used from the archival data set are finger tapping test scores, age, educational level, gender, ethnicity, diagnosis, compensation-seeking status (whether or not the person is in a lawsuit or attempting to obtain disability), and scores on other performance validity tests used for assigning subjects to credible and noncredible groups. |
