What type of interval recording is indicated by 'P'?

Partial interval recording is a type of interval recording method used in behavioral observation and data collection in Applied Behavior Analysis (ABA). This method involves observing whether a specific behavior occurs at any point during predetermined intervals of time. For example, if you are using a 10-minute interval, you would mark the occurrence of the behavior if it happens at least once during those 10 minutes, regardless of how long or how many times the behavior occurs within that timeframe.

This approach is particularly useful for behaviors that are likely to occur frequently or for which you want to understand presence or absence rather than duration. It allows practitioners to gather data on behaviors without requiring continuous observation, thus making it more feasible in various settings.

The use of partial interval recording is beneficial in measuring behaviors that are important to track for treatment and success, providing a simple yes/no measure that practitioners can use to demonstrate progress over time.
