• • interobserver agreement

• • observer reactivity

• • observer expectation

• • inadequate observer training

• What is not an indicator of trustworthy measurement?

• • Accuracy

• • Repeatability

• • Validity

• • Reliability

Dr Jane assessed her client, a child age 8, using the SIT, a relatively new test that measures stress indicators. In a meta-analysis, the test was found to be accurate and reliable when used in a population of age 4-17, but has questionable validity. What is the implication on Jane’s assessment results?

• The test is not suitable for her client’s age.

• The test will not yield consistent results.

• The test does not truly measure stress indicators, but something else.

• The results is consistent but it will not be accurate.

If a BCBA wants to reduce internal threats to measurement validity, what should they do?

• • Operationalize behaviors to be measured

• • Construct and adhere to a strict schedule of observations

• • Identify the correct dimensions of behavior to be measured

• • All of these

What is NOT a threat to accuracy and reliability of measurements?

• Poorly designed measurement systems

• Inadequate observer training

• Unintended influence on observers

• Dividing observations into intervals

Researchers can use multiple indices to assess the quality of their data when using IOA.F: Researchers can use multiple indices to assess the quality of their data when using IOA.

• True

• False
