RBT Measurement and Data Collection

Question 1

What is the purpose of data collection in ABA?

Accepted Answer

To make objective decisions about the effectiveness of interventions

Answer

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?

Accepted Answer

Partial interval recording

Answer

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:

Accepted Answer

The number of times a behavior occurs

Answer

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:

Accepted Answer

How long a behavior lasts from start to finish

Answer

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?

Accepted Answer

The time from the onset of a stimulus to the initiation of the response

Answer

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.
