Evidence for reliability and validity of attentional function evaluation using the ipad application “Touch the Numbers”

Abstract

Abstract: Objective: We have examined the reliability and validity of ipad application “Touch the Numbers”. Subjects: This study enrolled 34 healthy adult. Methods: An Intraclass correlation coefficient ICC (1, 1), as determined from the reproducibility of the Touch the Numbers, and Minimal Detectable Change were used to investigate the reliability. Additionally, a Pearsonʼs correlation coefficient, as determined from the association with TMT-A, was used to investigate the validity. Results: The ICC of the Touch the Numbers was high (0.66 [0.42-0.81]). A significant correlation was found between the TMTA and Touch the Numbers (r=0.57, p<0.01). Conclusions: Touch the Numbers was suggested to be applicable as a note function tests.
