RBT RBT Measurement and Data Collection 5 — Questions and Answers
Question 1: When graphing behavioral data, an RBT draws a vertical dashed line on the graph. This line most likely represents:
- A change in the target behavior definition
- A phase change or condition change (Correct answer)
- The client's goal line
- An error in data recording
Correct answer: A phase change or condition change
A vertical dashed line on a behavior graph indicates a phase change, such as moving from baseline to intervention.
Question 2: An RBT is instructed to collect data using a 10-second partial interval system during a 5-minute session. How many total intervals will be recorded?
- 10
- 30 (Correct answer)
- 50
- 300
Correct answer: 30
5 minutes = 300 seconds ÷ 10 seconds per interval = 30 total intervals.
Question 3: Which measurement dimension is MOST useful when the goal is to reduce the amount of time a client engages in stereotypic rocking?
- Frequency
- Latency
- Duration (Correct answer)
- Magnitude
Correct answer: Duration
Duration recording measures how long a behavior lasts, making it the most appropriate dimension when the goal is to reduce the total time spent engaging in a behavior.
Question 4: Two RBTs independently observe the same session and record frequency data for aggression. RBT A records 10 instances and RBT B records 8. What is the IOA percentage?
- 20%
- 80% (Correct answer)
- 90%
- 100%
Correct answer: 80%
For frequency IOA, divide the smaller count by the larger count: 8/10 × 100 = 80%.
Question 5: A client's behavior data shows a decreasing trend over several sessions during intervention. This pattern suggests the intervention:
- Is not working for a behavior targeted for reduction
- May be effectively reducing the target behavior (Correct answer)
- Should be immediately discontinued
- Needs a higher magnitude consequence
Correct answer: May be effectively reducing the target behavior
A decreasing data trend during intervention for a behavior targeted for reduction suggests the treatment is having a positive effect.
Question 6: When an RBT's presence changes how a client behaves during an observation, this is referred to as:
- Observer drift
- Reactivity (Correct answer)
- Social desirability bias
- Measurement error
Correct answer: Reactivity
Reactivity occurs when the presence of an observer influences the behavior being observed, potentially compromising data accuracy.
Question 7: Which of the following is an example of a permanent product recording?
- Recording each time a student raises their hand during class
- Counting the number of math problems completed correctly on a worksheet (Correct answer)
- Using a stopwatch to time how long a client stays seated
- Marking a data sheet each time a client hits a peer
Correct answer: Counting the number of math problems completed correctly on a worksheet
Permanent product recording involves measuring the tangible outcomes or results of behavior, such as completed worksheets, rather than the behavior itself as it occurs.
