Domain A Study Guide: Data Collection & Graphing
If you're looking to master the RBT concepts, Domain A is where it starts. Accurate data collection is mandatory in this line of work. With proper graphing and charting, you can efficiently detect behavioural patterns. Furthermore, it allows the supervisor to make critical decisions by steadily reviewing the client's status and progress. They can then implement appropriate interventions to negate the problematic behavioural patterns.
Here's an overview of all the Domain A sections you'll need to prepare for the RBT exam in accordance with the RBT 3rd Edition Task List:
A.1 Implement Continuous Measurement Procedures
The goal of continuous measurement is to record every relevant behaviour within the provided observation timeframe to build a behavioural dataset.
| Key Concepts | Definition | Example | Significance |
|---|---|---|---|
| Frequency | The number of times a behaviour takes place. | A patient uses slang 5 times. Frequency of behaviour = 5 | Suitable for behaviour that has a clear beginning and an end; possible to count separately. |
| Rate | Frequency in relation to time. | A patient uses slang 5 times in 10 minutes. Rate = frequency/time = 5/10 = 0.5 per minute | Best to compare the behaviour in different sessions. |
| Duration | The amount of time that a behaviour lasts. | A patient has a tantrum from 10.30 am to 10.45 am. Duration = 15 minutes. | Notes the length of each behaviour. |
| Latency | The difference between the time of instruction and the time of response. | An RBT says "Put down the remote". The patient does it 5 seconds later. Latency = 5 seconds. | Useful in determining response time throughout sessions. |
| IRT (Inter Response Time) | The elapsed time between two consecutive behaviours. | A patient throws the remote at 10.01 and then again at 10.09. IRT = 8 minutes. | Useful in identifying repetitive behaviour. |
A.2 Implement Discontinuous Measurement Procedures
Discontinuous measurement focuses on sampling data periodically rather than recording every instance of behaviour.
| Key Concepts | Definition | Example | Significance |
|---|---|---|---|
| Partial Interval Recording | The behaviour occurs at least once during the interval. | The target behaviour occurs for 5 seconds within a 30-second interval. | Identifies the interval as an occurring one. |
| Whole Interval Recording | The behaviour occurs prominently throughout the interval. | The target behaviour occurs for 25-30 seconds within a 30-second interval. | Identifies the interval as a non-occurring one. |
| Momentary Time Sampling | The instructor chooses to observe and record a target behaviour instantaneously. | The instructor checks for and records a behaviour every 10 minutes. Behaviour is only recorded if it takes place at the exact time. | Realistic approach when behaviour isn't continuous. |
A.3 Implement Permanent Product Recording Procedures
The RBT observes and measures the outcome of the behaviour rather than the behaviour itself. It's used when the behaviour leaves behind practical, observable, and measurable outcomes.
For instance, a learner is asked to write the names of 20 animals. Here, the completed worksheet is an instance of a permanent product.
Note: Permanent product recording is only applied in the absence of both continuous and discontinuous measurement procedures. It measures the result of the behaviour, and not the behaviour directly.
A.4 Enter Data and Update Graphs
By turning raw data into essential graphs and charts, RBTs can easily identify behavioural patterns and monitor patient progress.
A reporter must not —
- alter or round up data
- Enter incorrect data
- delay the process
A.5 Describe Behaviour In Observable and Measurable Terms
Observable and measurable terms refer to reporting the incident 'as is', without the use of prejudice, emotion, or personal assumptions.
For instance, instead of saying 'The patient was enraged', the behaviour can be described measurably as 'The patient yelled and slammed the doors twice'.
A.6 Calculate & Summarise Data
| Key Concepts | Definition | Example | Significance |
|---|---|---|---|
| Percentage | Number of correct responses divided by Total Opportunities × 100 | A patient provides 15 correct responses out of 20. Percentage = 15÷20 × 100 = 75% | Allows easy calculation of raw data. |
| Mean | The average duration of a target behaviour. | A child cries for 2, 4, and 6 minutes consecutively. Mean time of crying = (2+4+6)/3 = 12/3 = 4 minutes. | Helps to summarise data for better evaluation. |
A.7 Identify Trends in Graphed Data
Trends refer to the direction of data over time. Usually, there are three types of trends: increasing, decreasing, and stable.
In graphed data, an increasing trend indicates that the data move upward over time. In a decreasing trend, it moves downward. And in a stable trend, the data, i.e., the observable behaviour, remains fairly consistent.
A.8 Risks of Unreliable Data and Poor Procedural Fidelity
Procedural fidelity refers to the implementation of intervention procedures exactly as instructed. It facilitates the collection of reliable and consistent data.
