Branded App Usability: Speed

What it measures

Three items measure how quickly and responsively a branded mobile app processes user inputs and delivers information. This scale is one of five subscales developed by Baek and Yoo (2018) as part of a comprehensive branded app usability instrument. AVE was .70; convergent, discriminant, and nomological validity were supported.

Response format

Scale items

• The branded mobile app is very fast in responding to my feedback.
• The branded mobile app processes my input very quickly.
• I am able to obtain the information from the branded mobile app without any delay.
