Module 3 Quiz NURS 5366 Principles of Research in Nursing Score: 100 out of 100 A researcher is studying the effect of hypnosis on pain experienced during dental procedures. The researcher's study has two groups: those who receive hypnosis during the procedure and those who receive no hypnosis. If the researcher plans to use a t -test for the statistical analysis, which would be the best way to measure pain for this study? - Ans numerical pain scale with a range from 0 to 100 A researcher performs a se ries of pilot studies to evaluate whether a measurement tool produces consistent results. This is an evaluation of: - Ans Reliability A researcher develops a 7 -point Likert scale to evaluate feelings of well -being in patients who are undergoing chemothera py. The researcher administers this measure to other, similar patients in several medical centers. This is done in order to: - Ans improve the test -retest reliability In a pilot study to help train a group of data collectors who will evaluate children's p ain using a FACES rating scale, the researcher examines the reliability of the scores of each data collector. This is an example of which type of reliability measure? - Ans Interrater reliability A researcher evaluates scores of a paper and pencil instrum ent with variables at the interval level of data using the Cronbach's alpha coefficient statistical procedure. This is a test of: - Ans internal consistency reliability A researcher administers a scale measuring self -confidence and one measuring self -
doub t to a group of subjects and performs a correlational analysis of the results. This is a test of validity from: - Ans divergent validity A researcher develops a new instrument to measure coping skills and conducts a pilot study to compare the new tool wit h an existing tool that measures this concept. This is an example of evidence of validity from: - Ans Convergent validity A researcher evaluates whether a tool addresses the major elements of the construct being studied. This helps to ensure: - Ans content validity A researcher studying depression in relation to five predictor variables decides to include five more variables in the study because the literature reveals that they may also be involved in depression. Consequently, the researcher will do which of the following? - Ans Use a larger sample size.
