The Content and Construct Development of CGMs Device Adoption Model

摘要

The authors formed an instrument to facilitate the intention of wearable continuous glucose monitoring device adoption in smart healthcare system. Initial survey items were reviewed by five content experts for construct-fit and readability. Here, seven factors were identified from various researches to build up an adoption model of wearable Continuous Glucose Monitoring System. This research planned to develop and validate an adoption model for wearable CGMs device adoption. At this point, for eight constructs total 33 numbers of items were assessed by five academic experts related to information system department and finally, we selected 31 items for measurement. Meeting session was conducted with the experts in this study for content validation process. For the analysis content experts' unity, two quantitative approaches named Content Validity Ratio (CVR) and Content Validity Index (CVI) were performed. From 33 items, 31 were selected finally, as the CVR critical value is followed by 0.75 (N=5) and 2 items were rejected. In attendance, we also did some change in structure of the items as per the expert comments. After that, obtained items were calculated using CVI. The acceptable final value of CVI is 0.80. Face validation process was also applied to the items of the constructs by the experts as well. This instrument is possible to be prospective for the measurement of adoption model especially for wearable CGMs device in smart healthcare.
