Exam 14: Rigour in Research

A nurse researcher describes an instrument that produces the same result when it is administered to the same participants under similar conditions on two or more occasions as possessing what?

Which type of validity is demonstrated by administering a test in which all items relate to wound care,and then evaluating student performance in caring for patients with wounds in the clinical setting?

Which measures used to test reliability are specific for equivalence?

The inter-rater reliability of a new instrument is established as 48%.What is the correct interpretation of this finding?

Which type of reliability exists when consistency of observation,measured by a correlation coefficient,is noted between two or more research assistants who record their observations of an event at the same time?

A nurse researcher critiques a phenomenological study for fittingness.The researcher will examine the study to see whether the study included which of these elements?

An ear temperature probe that consistently reports body temperature at a degree lower than the patient's actual temperature has what type of reliability or validity problem?

Testing of a new instrument demonstrates that it has a high degree of internal consistency.What does this indicate to the nurse researcher?

Which of the following types of validity is the most difficult to establish?

A researcher developed a fatigue scale in an attempt to distinguish depression from fatigue in patients receiving radiation therapy for cancer.The researcher administered the new fatigue scale along with established instruments that measure depression.The fatigue scores were found to be negatively related to the indicators of depression.How should this information be interpreted?

What type of validity is demonstrated in measuring the cognitive knowledge of wound care by (1)administering a test in which all the items relate to wound care and (2)evaluating students' performance in caring for patients with wounds in the clinical setting?

A researcher who is developing a new instrument to measure pain has been told by experts and patients that the instrument has face validity.What should be the researcher's next step?

A nurse researcher administered a test anxiety questionnaire to a group of nursing students before they attended a test anxiety workshop and then administered a different questionnaire to the same nurses immediately following the workshop.This is indicative of which type of reliability?

A nurse investigator administers an Alcoholic Health Risk Appraisal instrument to participants attending an Alcoholics Anonymous meeting and to participants who belong to a religious sect known for its members' abstinence from alcohol.Which type of validity is this investigator attempting to establish?

Which type of validity is most difficult to establish?

A nurse researcher describes an instrument that is administered repeatedly and obtains the same results as having what?

A researcher developed an instrument to measure self-esteem and administered it to a group of individuals who were intravenous substance abusers and to a group of people who were not,expecting to see significant differences in scores between the two groups.How should this method of establishing construct validity be categorized?

When using the item-to-total correlation in testing an instrument that consisted of 25 items for homogeneity,8 items were found to have a low correlation to the total.How should the researcher use this information?

What is the method or format of Cronbach's alpha coefficient as a test for reliability?

The nurse researcher notes that test-retest correlations were r = 0.79 when given over 4-week intervals.This is interpreted to indicate what?
