Background: There are professional expectations for public health nurses to engage in and develop competencies in evidence-informed decision-making (EIDM). The purpose of this research study was to develop and psychometrically test a measure to assess competence in EIDM among public health nurses.
Methods: Guided by the Standards for Educational and Psychological Testing (American Educational Research Association, American Psychological Association, & National Council on Measurement in Education, 2014), a three stage study was employed to develop and psychometrically evaluate the new self-report EIDM Competence Measure: 1) Stage one: a systematic review of existing measures assessing four EIDM competence attributes of knowledge, skills, attitudes/beliefs, and behaviours; 2) Stage two: item development for the EIDM Competence Measure comprised of four subscales (knowledge, skills, attitudes/beliefs, and behaviours); and 3) Stage three: psychometric testing (reliability, validity, acceptability) which included item reduction from an original 40-item to a final 27-item tool.
Results: The EIDM Competence Measure consists of 27 items aligning with a four-factor model of EIDM knowledge, skills, attitudes/beliefs, and behaviours establishing internal structure validity. Cronbach’s alpha for these four factors was 0.96, 0.93, 0.80, and 0.94, respectively.
Significant associations between EIDM competence subscale scores and education, EIDM training/project involvement, and organizational culture established validity based on relationships to other variables. For the original 40-item tool, missing data was minimal as 93% of participants completed all items and mean completion time was 7 minutes and 20 seconds.
Conclusions: The EIDM Competence Measure is a conceptually and psychometrically robust instrument that has potential for use in public health nursing practice. / Dissertation / Doctor of Philosophy (PhD) / Nurses who work in public health have professional expectations to participate in evidence-informed decision-making (EIDM). Because of this, it is important to measure how competent they are in EIDM. The purpose of this study was to develop and test a tool that measures EIDM competence among public health nurses using a three-stage study. The first stage involved reviewing literature on existing tools that measure different components of EIDM competence including EIDM knowledge, skills, attitudes/beliefs, and behaviours among nurses. The second stage involved using existing tool items and developing new items for a new tool named the EIDM Competence Measure. In the third stage, the EIDM Competence Measure was tested to assess its validity, reliability, and acceptability among public health nurses in Ontario. The EIDM Competence Measure was found to have strong validity, reliability, and acceptability, showing that there is potential for its use in public health nursing practice.
