RBT Measurement and Data Collection 1 — Questions and Answers
Question 1: What is the purpose of data collection in ABA?
- To fill out paperwork for insurance
- To make objective decisions about the effectiveness of interventions (Correct answer)
- To keep the RBT busy between trials
- To compare clients to each other
Correct answer: To make objective decisions about the effectiveness of interventions
Data collection in ABA serves to provide objective, quantifiable evidence about the effectiveness of interventions. It allows the BCBA and treatment team to make data-based decisions about whether to continue, modify, or discontinue programs.
Question 2: Which measurement procedure records whether a behavior occurred at any point during a specified interval?
- Whole interval recording
- Partial interval recording (Correct answer)
- Momentary time sampling
- Frequency recording
Correct answer: Partial interval recording
Partial interval recording involves dividing the observation period into equal intervals and recording whether the behavior occurred at any point during each interval. If the behavior occurs at all during the interval, it is scored as occurring.
Question 3: Frequency recording measures:
- How long a behavior lasts
- The number of times a behavior occurs (Correct answer)
- The time between occurrences of a behavior
- Whether a behavior occurs at a specific moment
Correct answer: The number of times a behavior occurs
Frequency (or event) recording counts the number of times a behavior occurs during an observation period. It is best used for behaviors that have a clear beginning and end (discrete behaviors) and that do not occur at extremely high rates.
Question 4: Duration recording is most appropriate for measuring:
- How many times a behavior occurs
- How long a behavior lasts from start to finish (Correct answer)
- The time between the SD and the response
- The percentage of correct trials
Correct answer: How long a behavior lasts from start to finish
Duration recording measures the total amount of time a behavior lasts from onset to offset. It is most appropriate when the concern is how long a behavior continues, such as time spent on task, duration of tantrums, or time engaged in play.
Question 5: What does latency measure?
- The number of times a behavior occurs
- The time from the onset of a stimulus to the initiation of the response (Correct answer)
- The total time a behavior lasts
- The percentage of intervals in which a behavior occurs
Correct answer: The time from the onset of a stimulus to the initiation of the response
Latency is the measure of time from the presentation of a stimulus (such as an instruction) to the onset of the response. For example, measuring how long it takes a student to begin working after the teacher gives an instruction.
Question 6: An RBT is asked to record whether a behavior is occurring at the exact moment the interval ends. This is:
- Partial interval recording
- Whole interval recording
- Momentary time sampling (Correct answer)
- Frequency recording
Correct answer: Momentary time sampling
Momentary time sampling involves observing and recording whether a behavior is occurring at the precise moment the interval ends (or a timer goes off). It provides a snapshot of behavior at specific moments rather than continuous observation.
