Client Need: Safe and Effective Care Environment
Cognitive Level: Knowledge
Concept: Evidence-based practice
Difficulty: Easy
Feedback
1 This is correct. Test-retest reliability focuses on the stability of an instrument.
2 This is incorrect. Validity is the accuracy of an instrument, whereas test-retest reliability focuses on the stability of an instrument
3 This is incorrect. Test-retest reliability focuses on the stability of an instrument.
4 This is incorrect. The stability of an instrument is determined by the test-retest reliability.
PTS: 1 CON: Evidence-based practice
5.ANS:3
Chapter: Principles of Measurement
Chapter Learning Objective: 1. Compare and contrast the four types of scales of measurement.
Page: 241
Heading: Ordinal
Integrated Processes: Nursing Process
Client Need: Safe and Effective Care Environment
Cognitive Level: Application
Concept: Evidence-based practice
Difficulty: Easy
Feedback
1 This is incorrect. In addition to having all the characteristics of nominal and ordinal scales, interval levels of measurement have an equal interval size based on an actual unit of measurement.
2 This is incorrect. Categories in ratio scales are different, ordered, and separated by a constant unit of measurement, and ratio scales have an absolute zero.
3 This is correct. A rating scale from severe to low is an ordinal level of measurement. It specifies the order of items without specifying how far apart they are.
4 This is incorrect. Nominal measurements classify subjects into two or more categories, such as more or less. Data simply shows the frequency of the subject.
PTS: 1 CON: Evidence-based practice
6.ANS:3

Page: 245
Heading: Reliability
Integrated Processes: Nursing Process

Cognitive Level: Knowledge
Concept: Evidence-based practice
Difficulty: Easy
Feedback
1 This is incorrect. Test-retest is a type of reliability that tests the consistency of measurements.
2 This is incorrect. Interrater reliability is measured by the degree of agreement among raters.
3 This is correct. Content is not a type of reliability.
4 This is incorrect. Internal consistency is a type of reliability that measures the consistency of the instruments.
PTS: 1 CON: Evidence-based practice
7.ANS:4

Heading: Criterion-Related Validity
Integrated Processes: Nursing Process
Client Need: Safe and Effective Care Environment
Cognitive Level: Knowledge
Concept: Evidence-based practice
Difficulty: Easy
Feedback
1 This is incorrect. Concurrent validity and predictive validity are types of criterion-related validity evidence.
2 This is incorrect. Predictive validity and concurrent validity are types of criterion-related validity evidence.
3 This is incorrect. Internal consistency is a type of reliability measurement.
4 This is correct. Both concurrent validity and predictive validity are types of criterion-related validity evidence.
PTS: 1 CON: Evidence-based practice

Difficulty: Easy
Feedback
1 This is incorrect. Various approaches to measuring aspects of the same thing can be useful.
2 This is correct. Whenever data are collected, some amount of error is always encountered.
3 This is incorrect. Present day behavior predicts future behavior.
4 This is incorrect. Testing and assessment benefit society.

Cognitive Level: Comprehension
Concept: Evidence-based practice
Difficulty: Easy
Feedback
1 This is correct. Test-retest reliability is determined by measuring consistency of scores over time.
2 This is incorrect. Split-half reliability is determined by measuring the consistency of scores obtained from two equivalent halves of the same examination.
3 This is incorrect. Internal consistency reliability is measured by the degree of consistency with which a test measures a single construct/concept.
4 This is incorrect. Interrater reliability is determined by the measure of degree of agreement between two or more scores.
PTS: 1 CON: Evidence-based practice

Cognitive Level: Comprehension
Concept: Evidence-based practice
Difficulty: Moderate
Feedback
1 This is incorrect. Construct validity refers to how well an instrument measures an intended hypothetical concept.
2 This is incorrect. Criterion-related validity refers to how well an instrument measuring a particular concept compares with a criterion, providing more quantitative evidence on the accuracy of the instrument.
3 This is correct. Content validity refers to how well the particular sample of behaviors used to measure a characteristic reflects the entire domain of behaviors that constitutes that characteristic.
4 This is incorrect. Face validity refers to how well a test is subjectively viewed as covering the content it measures.
