ABA Behavioral Evaluation & Data Collection 2

Question 1

A BCBA wants to measure the duration of a client's tantrum behavior. Which data collection method is most appropriate?

Accepted Answer

Duration recording

Answer

Duration recording measures the total time a behavior occurs from onset to offset, making it ideal for tantrum behavior.

Question 2

When conducting a structured ABC observation, which component represents the antecedent?

Accepted Answer

The event or stimulus that precedes the behavior

Answer

The antecedent is the environmental event or stimulus that occurs immediately before the target behavior.

Question 3

Which reliability measure is most appropriate when evaluating interobserver agreement for duration data?

Accepted Answer

Duration IOA (smaller/larger ratio)

Answer

Duration IOA calculates agreement by dividing the smaller duration by the larger duration for each observation period.

Question 4

A behavior analyst uses 10-second partial interval recording. Which of the following is true about this method?

Accepted Answer

It tends to overestimate the true frequency of behavior

Answer

Partial interval recording scores an interval as positive if the behavior occurs at any point, which tends to overestimate the actual prevalence.

Question 5

A clinician tracks how long it takes a child to begin a task after an instruction is given. This measurement is called:

Accepted Answer

Latency

Answer

Latency measures the time elapsed between the onset of a stimulus (instruction) and the initiation of the target behavior.
