Usability Test of eHealth Promotion @HKIEd—A Community of Practice Platform to Promote Healthy Lifestyles

Abstract

Community of Practice (CoP) has been proved as an effective means for co-creation of knowledge. It is not yet widely used in health promotion, not to mention to utilize technological environment such as Web 2.0 to add value to the CoP. Under this study, an eHealth promotion @HKIEd, a CoP platform to promote healthy lifestyles was designed and constructed. It helped facilitate the CoP to share useful health information, locate expertise, promote health related events, communicate health updates effectively, co-construct shared repertoire of knowledge and build shared best practice on effective health promotion which was not limited to time, space and distance. Usability test was conducted to evaluate user acceptance of the eHealth promotion CoP platform using the Computer System Usability Questionnaire. A random sample of eighty-three active participants was recruited. Fifty females and thirty-three males with mean (S.D.) aged 21.1 were asked to evaluate the e-platform. The average scores of each domain were calculated with the corresponding means of the average scores of System Use , Information Quality and Interface Quality being 2.69, 2.83 and 2.74 respectively. The overall usability was 2.48 and the eHealth promotion @HKIEd demonstrated a high usability. It will provide a promising way to disseminate information for the public in health awareness promotion.
