What is required for whole interval recording (WIR)?

Whole interval recording (WIR) is a data collection method used to measure the occurrence of a behavior during a specified time interval. For WIR to be considered successful, the behavior in question must occur throughout the entire duration of the interval. This means that if the behavior is observed at any point within the time frame, it would not be counted unless it occurs continuously for the entire interval.

This method is particularly useful for certain behaviors where the goal is to promote engagement or sustained behavior over time, such as social interactions or participation in an activity. In WIR, if the behavior does not last for the full interval, it will not be recorded, emphasizing the importance of continuous occurrence during the entire observation period.

The requirement for whole interval recording is instrumental in assessing behaviors that are expected to be sustained, as opposed to those that may spike infrequently or occur sporadically. Understanding this concept is crucial for accurately collecting data that reflects the desired functional or educational outcomes in behavioral assessments.
