Free BCAT Behavioral Data Collection Questions and Answers

Question 1

A client screamed 10 times during a 30-minute session on Monday and 10 times during a 60-minute session on Wednesday. To accurately compare the screaming behavior across these two sessions, which measurement should the BCAT report?

Accepted Answer

Rate, because the observation times were different.

Answer

Rate (calculated as frequency divided by time) is the most accurate measure for comparing behavior when the observation periods are of unequal length. A simple frequency count of 10 is misleading because the behavior occurred more intensely (10 times in 30 minutes) on Monday than on Wednesday (10 times in 60 minutes).

Question 2

A supervising BCBA wants to know the total amount of time a client engages in tantrum behavior from its beginning to its end. Which continuous measurement system should the BCAT use to collect this data?

Accepted Answer

Duration

Answer

Duration recording is the appropriate method for measuring the total time that a behavior occurs, from its onset to its offset. Frequency counts how many times, latency measures time from a cue to the response, and IRT measures time between responses.

Question 3

Which of the following is the BEST example of data collection using permanent product recording?

Accepted Answer

Checking a worksheet for the number of correctly solved math problems.

Answer

Permanent product recording involves measuring the tangible outcomes or environmental effects of a behavior after it has occurred. The completed worksheet is a physical 'product' that can be measured, whereas the other options describe direct observation of the behavior as it happens (frequency, duration, and momentary time sampling).

Question 4

A BCAT is using partial interval recording with 1-minute intervals to measure a client's out-of-seat behavior. The client gets out of their seat for 5 seconds during the first interval and for 30 seconds during the second interval. How should the BCAT score these two intervals?

Accepted Answer

Mark both the first and second intervals.

Answer

In partial interval recording, the observer marks the interval if the target behavior occurred at any point during that interval, regardless of its duration. Since the client was out-of-seat during both intervals, both intervals are marked as an occurrence.

Question 5

A technician gives the instruction, "Clap your hands." The technician starts a timer immediately after giving the instruction and stops the timer as soon as the client begins to move their hands to clap. What dimension of behavior is being measured?

Accepted Answer

Latency

Answer

Latency is the measure of time that elapses between an antecedent stimulus (the instruction) and the initiation of the response (starting to clap). Duration would measure how long the clapping lasts, IRT would measure the time between claps, and rate would measure claps per unit of time.
