NURS5366 Principles Of Research In Nursing.

NURS5366 Principles Of Research In Nursing. Question 1 5 / 5 pts 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? numerical pain scale with a range from 0 to 100 patient report of presence or absence of pain pain scale where the participants report their pain as: none, some, intense p. 411 Question 2 5 / 5 pts A researcher performs a series of pilot studies to evaluate whether a measurement tool produces consistent results. This is an evaluation of: Readability Accuracy Reliability Validity Module 3 Quiz: 2202-NURS-5366-401-PRINC OF RESEARCH IN NURSING 3/15 page 370 Question 3 5 / 5 pts A researcher develops a 7-point Likert scale to evaluate feelings of wellbeing in patients who are undergoing chemotherapy. The researcher administers this measure to other, similar patients in several medical centers. This is done in order to: improve the test-retest reliability strengthen the operational definition of the constructs increase interrater reliability Decrease mono-operation bias page 370 Question 4 5 / 5 pts In a pilot study to help train a group of data collectors who will evaluate children’s pain 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? Module 3 Quiz: 2202-NURS-5366-401-PRINC OF RESEARCH IN NURSING 4/15 Internal consistency reliability Test-retest reliability alternate forms reliability Interrater reliability page 372 Question 5 5 / 5 pts A researcher evaluates scores of a paper and pencil instrument with variables at the interval level of data using the Cronbach’s alpha coefficient statistical procedure. This is a test of: internal consistency reliability interrater reliability alternate forms reliability test-retest reliability page 373 Question 6 5 / 5 pts Module 3 Quiz: 2202-NURS-5366-401-PRINC OF RESEARCH IN NURSING 5/15 A researcher administers a scale measuring self-confidence and one measuring self-doubt to a group of subjects and performs a correlational analysis of the results. This is a test of validity from: equivalence convergence contrasting groups divergent validity page 382 Question 7 5 / 5 pts A researcher develops a new instrument to measure coping skills and conducts a pilot study to compare the new tool with an existing tool that measures this concept. This is an example of evidence of validity from: Convergent validity Readability Contrasting groups Divergent vality
