At the end of the study, their personal factors of ease of use and usefulness of the system were asked using a 5-point Likert scale, with higher numbers corresponding to more positive ratings.
There was substantial variation of opinion about their EHR system and expectations of the ease of use and usefulness of the GEM (Table 3).
The results showed a significant, positive impact of the perceived "ease of use" and "usefulness" of the survey app as the technological medium of data collection on the participants' "satisfaction" and "intention" to continue participating in the corresponding survey.
That is, the experience of using a technology now directly influences the perception of the ease of use and usefulness of the technology, which consequently affects the intention to continue using it.
In addition, according to the results of the questionnaire, most of the participants perceived the ease of use and usefulness of the proposed system.
The aim of this stage of the project was to test the acceptability, ease of use, and usefulness of the intervention for the target population.
This questionnaire consisted of five-point Likert-type scales to gauge: (1) the perceived values related to HIT and patient care within the practice; (2) the perceived ease of use and usefulness of the practice's existing EHR system; (3) the awareness of the GEM intervention, and; (4) the expected ease of use and usefulness of the GEM.
Taken together, user-intuitive interface signs are critical for improving both ease of use and usefulness of a web application.
The instruments used in this study include questionnaires on self-regulation, self-efficacy for English and mobile devices, perceived ease of use and usefulness of the system, and an achievement test on the plants.
In 2000, Lederer, Maupin, Sena, and Zhuang [13] conduct an e-mail survey sent to 163 participants to express their opinions about ease of use and usefulness of websites.
