Cognitive, mood, and functional evaluations using touchscreen technology.
We describe the design and development of the Cognitive Evaluation Protocol (CEP), a computer software program for evaluating cognitive and functional capacities and mood. The program is self-administered by subjects using touchscreen monitors for input. Stimuli in CEP subtests are randomized to reduce the effects of learning on repeated assessments. Findings demonstrate that a) minimum instruction is required for touchscreen use, even for computer-naive subjects; c) both normative subjects and psychiatric patients respond positively to self-administered evaluations; and c) CEP can be used for within-subject repeated evaluations with minimal distortion of results due to practice effects. The CEP Report Generator provides immediate printed performance results and creates a database for long-term digital storage and information use.
