Abstract:
Purpose: The aim of this study was to develop and pilot-test a Web usability questionnaire specifically designed for use by older adults (the Perceived Health Web Site Usability Questionnaire [PHWSUQ]). Background: With an increasing number of older adult online users, the Internet has become recognized as an efficient medium to disseminate health information to these individuals. Usability of health Web sites is particularly important for older adults who have unique design needs. Although several Web usability questionnaires have been developed for younger adults, there is a lack of such measure for older adults. Methods (Design, Participants, Setting, Data Collection, Analytic approach): The PHWSUQ was developed based on an extensive review of the literature and consultation with usability experts and older adult online users. The preliminary psychometric aspects of the measure were assessed in a study that examined usability of three health Web sites. This usability study employed heuristic evaluations by usability experts and user tests (including the PHWSUQ) by ten older adult online users. The reliability of the PHWSUQ was assessed by estimating the internal consistency. The construct validity of the measure was examined by comparing the scores from the PHWSUQ with the findings from the heuristic evaluations. Results: The final version of the PHWSUQ included 12 items that assessed three usability attributes (Satisfaction, Ease-of-Use, and Usefulness), using a 7-point Likert scale. The alpha coefficients of each subscale and the overall scale of the PHWSUQ ranged from .64 to .93. The findings from the heuristic evaluations concurred with the scores from the PHWSUQ. Conclusions and Implications: The findings provided some evidence of internal consistency and construct validity for the PHWSUQ that was developed for older adults. The major limitation of this study was its small sample size. Further psychometric testing is needed with larger samples on additional health Web sties.
