Creating and Validating a Questionnaire for Assessing Dentists’ Self-Perception on Oral Healthcare Management—A Pilot Study

Abstract

Background and Objectives: Questionnaires designed to test knowledge and self-perception can be valuable tools for diagnosing a dentist’s understanding of the management and administration of a practice. The objective of this study was to create and authenticate a questionnaire for assessing dentists’ self-perception on oral healthcare management developed from discussions with experts in this field. Material and Methods: In order to create and verify a questionnaire survey, a cross-sectional, descriptive, and analytical study was carried out. Participants’ personal information and 31 statements across four categories made up the final questionnaire form. The answers to the questionnaire were in the form of a Likert scale. After refining the initial version, a total of 36 interviews were conducted at dental offices to verify the validity. For the Exploratory Factor Analysis (EFA), we used the Kaiser–Meyer–Olkin (KMO) index, the Bartlett sphericity test, and also Cronbach alpha coefficient for the validity of the questionnaire. Results: The accuracy of the instrument was measured by intrarater and interrater reliability. For the EFA, all the communalities exceeded the threshold of 0.05. With a Cronbach’s alpha coefficient of 0.898, the questionnaire has sufficient internal consistency. Conclusions: The questionnaire demonstrates robust reliability and validity, thereby affirming its suitability for its intended purpose.

Construction and Ranking of Usability Indicators for Medical Websites Based on Website User Experience

“…If the loading difference between two items on the same factor was less than 0.05, one of the items was removed and the analysis was re-run. Items associated with a factor with a communality of less than 0.4 or a maximum loading of less than 0.35 were also excluded [87]. After multiple rounds of selection and rotation, four common factors with eigenvalues greater than 1 were ultimately identified, and 24 indicators related to the usability of medical websites were retained.…”
