The video provides a tutorial on continuous measurement in applied behaviour analysis (ABA). It covers various types of continuous measurements. Imagine you are a behaviour analyst working with a child named Alex, who has difficulty staying seated during the class. You decide to use continuous measurement to track Alex’s behaviour and implement interventions.
Types of continuous Measurement:
- Frequency: Counting the number of times a behaviour occurs. Example- you note every time Alex gets out of their seat during a 1 hour class. If Alex gets up 10 times, the frequency is 10.
- Rate: Frequency divided by time, showing how often a behaviour occurs per unit of time. Example- If Alex gets up 10 times during 1 hour class, the rate is 10 times per hour.
- Duration: Measuring how long a behaviour lasts. Example- you record the total amount of time Alex spends out of his seat. If Alex gets up 10 times and each time lasts 1 minute, the total duration is 10 minutes.
- Inter- Response Time (IRT): Time between two consecutive instances of a behaviour. Example- If Alex gets up 10:05 AM and again at 10:10 AM, the IRT is 5 minutes.
- Trials to Criterion: Number of trials to achieve a set criterion. Example- you set a goal for Alex to stay seated for at least 30 minutes. It takes 5 days of practice (or trials) for Alex to reach this goal.
- Percent of Occurrence: Percentage of times a behaviour occurs out of a number of trials. Example- If you observe 20 instances during the week and Alex stays seated 15 times, the percept of occurrence is 15/20 x 100= 75%
The video is aimed at Registered Behaviour Technicians (RBTs) and Board Certified Behaviour Analysts (BCBAs) preparing for their exams. It includes definitions, examples, and practice questions to help viewers understand and apply these concepts.
