Which measurement method is most suitable for recording decreasing behavior?

The most suitable measurement method for recording decreasing behavior is partial interval recording. This method involves dividing the observation period into smaller intervals and recording whether the behavior occurred at any point during each interval. It is particularly effective for identifying trends in behavior, especially when the goal is to reduce the frequency of a behavior.

Partial interval recording is advantageous because it doesn't require continuous observation of the behavior; instead, it allows for each interval to be checked briefly. This can help in determining if there is a noticeable decrease in behavior over time. For behaviors that are being actively targeted for reduction, the partial interval method provides the feedback necessary to assess progress effectively.

Other methods might be less suitable for this purpose. Whole interval recording, for example, requires the behavior to occur during the entire interval to be recorded, which may not capture instances of decreasing behavior effectively if the behavior is infrequent. Momentary time sampling provides only a snapshot of behavior at specific moments, which may not accurately reflect decreasing patterns over time. Continuous measurement tracks every instance of behavior but can be impractical for observing duration trends in decreasing behavior, particularly in environments with many competing stimuli. Thus, partial interval recording uniquely aligns with the goals of monitoring and assessing decreasing behavior.
