A group of researchers developing an instrument to measure hope performed a test-retest on the  instrument with an interval of 5 days.  This testing resulted in a correlation coefficient of 0.38.  How should  the nurse interpret these findings?  ~ Instrument is unstable; low reliability A nurse researcher is critically appraising a research report and asks the question, “is a rationale given for  why a particular instrument or methods was selected?”  Which data-collection methods and procedures  would this question evaluate?  ~ Physiologic measurement A nurse researcher is seeking evidence about efficacy of pressure-reduction surfaces on development of  pressure ulcers in surgical patients.  Which database is most likely to yield the highest-level evidence?  Cochrane Review A nurse researcher writes an article for a professional journal based on his previously conducted research  on variables that predict obesity in children.  This research activity is described as research:  Dissemination Be careful because the reason I missed this is because there are 2 questions alike.  How can a nurse researcher assess the degree to which individual items on a scale cluster together  around multiple dimensions?  ~ Factor analysis How should a nurse researcher describe an instrument that is administered repeatedly and obtain the  same results?  ~ Indicative of reliability How should a research consumer evaluate the following statement in such a report?  “A positive  correlation was found between the variables of self-reported sleep adequacy and performance on the  driving simulator (r=0.21), although the correlation did not reach statistical significance.  ~ The  relationship between the variables is too weak to have practical application. How should researchers and reviewers accept statistical significance?
