A Tablet-PC-Based Cancellation Test Assessing Executive Functions in Older Adults

Objective To examine older adults' performance on a newly developed tablet-PC-based cancellation test (e-CT) and to study its psychometric properties. Methods 94 older adults with normal cognitive functioning were recruited. The effects of age, education, sex, and experience with computer-based...

Description
Summary:Objective To examine older adults' performance on a newly developed tablet-PC-based cancellation test (e-CT) and to study its psychometric properties. Methods 94 older adults with normal cognitive functioning were recruited. The effects of age, education, sex, and experience with computer-based devices on the e-CT were examined. Construct validity was tested by correlating the e-CT with established measures of executive functions (EF) and episodic memory. Correlation coefficients were used to assess short-term test–retest reliablity. Results The mean age of participants was 74.6 (SD: 7.3) years and 78% were women. Sixty-nine percent had higher education level (> high school) and 76% used computer-based devices daily. The correct cancellations (CC) on the e-CT ranged from 18 to 56, with a mean (SD) of 40.3 (5.7). The CC was inversely correlated with advancing age (rs  = −0.59, N = 94, p
