Answer 2

1. Practicality

2. Psychometric properties

Question 3

Practicality is ______? What influence that ? (5)

Answer 3

Usability of the test

1. Medical permission or supervision required and available
2. Time needed to administer and score the test
3. Personnel and expertise needed to administer the test
4. Level of fatigue to participant per test
5. Is the test meaningful to your participants

Question 4

Psychometric properties (4)

Answer 4

1. Reliability
2. Validity
3. Discrimination power
4. Performance standards

Question 5

Reliability (5)

Inter-rater reliability (1)

Answer 5

1. Refers to the degree that two test scores are similar under identical conditions
2. Test will then be free of measurment error
3. Referred to as test re-test-reliability
4. Should be more 0.8
5. Must originates from published protocol
6. When scores obtain from multiple tester are very similar (high correlation)

Question 6

Validity (2)
Criterion-related validity (2)
Content validity (2)
Predictive validity (2)

Answer 6

1. refers to the test having show to measure what it is intended to measure.
   2 Mot important characteristic of any test
2. Evaluates a test’s validity by comparing its scores with other scores already found to be valid
3. Acceptable when correlation is more 0.7
4. Degree to which a test measure the domain of interest
5. Determined by experts in the filed
6. Ability of a test to predict the futur outcome of the test
7. Research date must show a strong statistical prediction to the futur outcome

Question 7

Discrimination Power (2)

Answer 7

1. Ability of the test to detect changes in performance over time
2. Should have minimum floor and ceiling effects

Question 8

Performance standards (2)

Answer 8

Interpretation of the scores (provide feedback to participants

1. Norm-referenced standards: Evaluates by comparing others to the same gender & age
2. Criterion-referenced standard: Evaluates performance in relation to a particular reference point of specific goal such as fitness to climb stairs or to remain functionally independent.

Question 9

5 good reason for using the SFT

Answer 9

1. Meets psychometric properties
2. Is convenient and practical in terms of equipment, training space and time requirements.
3. Has norms-referenced standards for the interpretability of test results
4. Allow OA to perform task safely without need of medical release.
5. Evaluates a wide range of physical activities and function.

Question 10

Fullerton advanced balance scale has high: ? (4)

Answer 10

1. Predictive validity
2. test-re-test-reliability
3. intra & interrater reliability
4. content validity

Question 11

Interpreting test result of the SFT for
Performance norms:? (2)
Criterion standard:? (2)

Answer 11

PN

• Norms based on over 7000 community dwelling OA between 60 and 94 y/o
• “Normal” defined as the middle 50% of the population

CS

• Scores compared to a threshold score
• Can be used to identify participants at risk for mobility problem, falls, or disability
