RBT Task List 2nd Edition Measurement and Data Flashcards

Which measurement method records whether a behavior occurred at least once during each interval, regardless of how many times it occurred?

Answer: Partial interval recording

Partial interval recording scores an interval as positive if the behavior occurs at any point during that interval, even once.

An RBT measures how long it takes a student to begin a task after an instruction is delivered. This is a measure of:

Answer: Latency

Latency is the time elapsed between the onset of a stimulus (instruction) and the beginning of the response.

A client engages in hand-flapping. An RBT records every instance of the behavior each minute. This is an example of:

Answer: Frequency (event) recording

Frequency (event) recording tallies each individual occurrence of the behavior within an observation period.

Which measurement method is most appropriate for behaviors that are very high-rate or that do not have a clear beginning and end?

Answer: Time sampling (partial interval or MTS)

Time sampling procedures are designed for continuous or high-rate behaviors because recording each discrete occurrence would be impractical.

Two RBTs simultaneously and independently observe the same client and record the same behavior. They compare their data afterward to assess consistency. This is called:

Answer: Interobserver agreement (IOA)

IOA (interobserver agreement) measures the degree of consistency between two independent observers recording the same behavior.

Momentary time sampling (MTS) records whether a behavior is occurring:

Answer: Only at the exact moment the interval ends

MTS records behavior only at the precise moment the interval ends (or begins), not throughout the interval.

An RBT records the time from when a tantrum begins to when it ends for each occurrence. This is an example of:

Answer: Duration recording

Duration recording captures how long a behavior lasts from onset to offset.
