Quebec User Evaluation of Satisfaction with Assistive Technology (QUEST 2.0)

A 12-item questionnaire measuring satisfaction with an assistive technology device and related services.

By Claire White

What it measures

The QUEST 2.0 asks users to rate 12 aspects of their assistive technology experience: eight that concern the device itself (dimensions, weight, ease of adjustment, safety, durability, simplicity of use, comfort, and effectiveness), and four that concern services received (delivery, repairs and servicing, professional services, and follow-up). Users then identify the 3 most important items to them.

What the result tells you

Mean scores per subscale (device and service) and overall (1 to 5) indicate satisfaction level. Lower scores identify specific device features or service aspects that need improvement. The QUEST is used in BCI and AAC research to evaluate user acceptance and guide iterative design. It is applicable to people with locked-in syndrome evaluating communication devices.
