Psychosocial Impact of Assistive Devices Scale

A 26-item self-report questionnaire designed to measure the psychosocial impact of an assistive technology device on a person's functional independence, well-being, and quality of life. PIADS assesses three subscales: competence (subjective feelings of competence, productivity, and usefulness), adaptability (willingness to try new things and take advantage of new opportunities), and self-esteem (including security, sense of power, control, and self-confidence). Developed by Jeffrey Jutai and Hélène Day, PIADS is one of the few validated instruments specifically designed for assistive technology evaluation rather than adapted from general usability measures, making it particularly valuable for understanding whether an AT positively affects a user's sense of capability and independence beyond mere task completion.
