The validity and applicability of the Chinese version of the Quebec User Evaluation of Satisfaction With Assistive Technology for people with spinal cord injury.
The Quebec User Evaluation With Assistive Technology (Version 2.0; QUEST 2.0) has become an important outcome assessment to capture user satisfaction in the field of assistive technology. The purpose of this study is to investigate the psychometric properties of the Chinese version of the QUEST 2.0 (C-QUEST) in terms of content and substantive and factor validity and to explore its applicability on user satisfaction on mobility and equipment among Chinese people with spinal cord injury. A group of six expert members were invited to evaluate the content validity and translation quality of the 12-item C-QUEST. The revised version, along with the brief version of the World Health Organization Quality of Life Questionnaire (WHOQOL-BREF [HK]), was administered on user satisfaction of people with spinal cord injury in the community. The content validity and item performance were evaluated to be satisfactory. Exploratory factor analysis with varimax rotation agreed with the bidimensional structure of Device and Services in the construct of user satisfaction (61.06% variance explained). Items in WHOQOL-BREF (HK) were shown to have positive and moderate correlations with C-QUEST Device items (r = .412-.567, p < .05) but no significant associations with the Services items (p > .05). The 12-item C-QUEST was shown to be a valid and relevant instrument to capture the user satisfaction among Chinese people with spinal cord injury in the context of mobility and seating equipment.
