Evaluating a Digital Visual Perception Assessment Interface: User Performance, Usability, and Group Differences

Appropriate assessment content and a user-friendly interface are crucial for digital cognitive assessments. This study evaluated the Cognitive Assessment for Mobile Visual Perception (CA-MVP), a digital adaptation of visual perception tasks derived from the Dynamic Loewenstein Occupational Therapy Cognitive Assessment. Ninety-four healthy adults were categorized by age (young, middle-aged, and older) and educational level (low, medium, and high). Participants completed the conventional assessment first and CA-MVP one week later. Results showed good agreement between formats for total scores and moderate agreement for total completion time. Total scores did not differ significantly between formats, whereas completion time was significantly shorter in the digital format, although this may partly reflect fixed-order practice effects. CA-MVP demonstrated good usability. Task scores varied by age and education, completion times varied by age, and usability varied by age group. These findings have important design implications for improving assessment content and interface design in future digital adaptations.
