RBT RBT Measurement and Data Collection 4

Question 1

A client engages in self-injurious behavior (SIB) that occurs in rapid bursts making it impossible to count each instance individually. Which measurement system is MOST appropriate?

Accepted Answer

Partial interval recording

Answer

Partial interval recording is best for behaviors occurring in rapid bursts that are difficult to count individually, as it captures whether the behavior occurred at any point during each interval.

Question 2

During a 30-minute session, a client's appropriate play behavior was observed during 18 of 30 intervals using whole interval recording. What is the percentage of intervals?

Accepted Answer

60%

Answer

Percentage = (intervals with behavior / total intervals) × 100 = (18/30) × 100 = 60%.

Question 3

An RBT is using momentary time sampling with 1-minute intervals over a 10-minute observation. The client is on-task at the moment of observation in 6 of 10 intervals. What does this tell us?

Accepted Answer

The client was on-task at 60% of the sampled time points

Answer

Momentary time sampling only reflects what is happening at the exact moment of observation, not the total duration of the behavior.

Question 4

Which data collection method would BEST capture the number of words spoken by a client during a language intervention session?

Accepted Answer

Frequency recording

Answer

Frequency recording counts the number of discrete occurrences, making it ideal for tallying individual words spoken.

Question 5

An RBT records the time from when an instruction is given to when the client begins the response. This is called:

Accepted Answer

Latency recording

Answer

Latency recording measures the time elapsed between the presentation of a stimulus (instruction) and the initiation of the response.
