In order to measure social cognitive constructs in the oral hygiene domain, questionnaires containing self-efficacy and outcome expectation items were developed. Items were generated to measure personal beliefs in brushing and flossing ability under a variety of circumstances, and expected outcomes from performing oral hygiene behaviors that might be positive, negative, primary and secondary. In the first study, factor scales were developed on the basis of the responses from 90 subjects awaiting dental treatment. Principal components analyses with varimax rotation revealed two self-efficacy and four outcome expectations dimensions that explained 73% and 51% of the variance, respectively. A second study that utilized 103 government employees was conducted to evaluate the psychometric properties of the questionnaires. All scales demonstrated good internal consistency and test-retest stability. Correlations with extra test measures provided preliminary evidence for the validity of the instruments.
In this pilot study, the use of scribes resulted in an increased number of patients seen per hour per physician. Because this was a small study at a single centre, further research on the effects of scribes in Canada is warranted.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
