RBT RBT Task List 2nd Edition Measurement and Data 5 — Questions and Answers
Question 1: Which of the following best describes the purpose of graphing behavioral data in ABA?
- To satisfy legal documentation requirements only
- To visually display data for ongoing decision-making about treatment (Correct answer)
- To replace the need for written session notes
- To compare a client's performance to national norms
Correct answer: To visually display data for ongoing decision-making about treatment
Graphs provide a visual display of behavior over time, allowing supervisors and RBTs to make informed, data-based treatment decisions.
Question 2: An RBT is instructed to collect data using a permanent product recording method. Which of the following would be an appropriate target for this approach?
- Number of times a client yells during lunch
- Number of worksheets completed correctly (Correct answer)
- Time spent engaged in stereotypy
- Latency to comply with a verbal instruction
Correct answer: Number of worksheets completed correctly
Permanent product recording involves measuring tangible outputs (e.g., completed worksheets) that remain after the behavior has occurred.
Question 3: During a session, a client's problem behavior occurs 0 times. The RBT should:
- Skip data collection since there is nothing to record
- Record zero occurrences on the data sheet (Correct answer)
- Estimate behavior based on previous sessions
- Notify the BCBA that the behavior was not measureable
Correct answer: Record zero occurrences on the data sheet
Zero occurrences are meaningful data points that must be recorded, as they reflect a genuine absence of the target behavior.
Question 4: A supervisor reviews an RBT's data and notices the graph shows a clear upward trend in problem behavior over two weeks. What does this trend suggest?
- The treatment is effectively reducing the behavior
- The behavior is increasing and the current intervention may need adjustment (Correct answer)
- The data collection method is unreliable
- The client has reached their behavioral goals
Correct answer: The behavior is increasing and the current intervention may need adjustment
An upward trend in problem behavior over time indicates the intervention is not working as intended and a program modification may be needed.
Question 5: Which of the following is an example of a continuous measurement procedure?
- Momentary time sampling every 10 minutes
- Partial interval recording in 30-second intervals
- Frequency count of every instance of a behavior across the full session (Correct answer)
- Spot-checking behavior at random times
Correct answer: Frequency count of every instance of a behavior across the full session
Continuous measurement (e.g., frequency counting every instance) captures all occurrences of a behavior throughout the entire observation period.
Question 6: An RBT is unsure whether she is implementing data collection procedures correctly. What is the most appropriate action?
- Continue collecting data and hope results look correct
- Ask a fellow RBT to verify her technique without notifying the BCBA
- Consult the BCBA supervisor for clarification and additional training (Correct answer)
- Modify the data collection method independently to simplify it
Correct answer: Consult the BCBA supervisor for clarification and additional training
RBTs must seek guidance from their BCBA supervisor when uncertain about procedures to ensure data integrity and treatment fidelity.
Question 7: Inter-response time (IRT) measures the:
- Total duration of a behavior across a session
- Time between the end of one response and the beginning of the next (Correct answer)
- Number of responses per unit of time
- Time from a stimulus to the onset of a response
Correct answer: Time between the end of one response and the beginning of the next
IRT is the elapsed time between the end of one response instance and the start of the next, reflecting how frequently behaviors are 'spaced.'
