Which method would you use to understand how frequently a behavior occurs?

Using a frequency count is the most effective method for understanding how frequently a behavior occurs. This approach involves tallying the number of times a specific behavior takes place within a defined observation period. It provides clear and quantifiable data that reflects the actual occurrences of the behavior, allowing therapists to identify patterns or changes over time.

In contrast, interval time sampling captures whether a behavior occurs within specific time intervals, but it does not provide exact numbers for how many times the behavior happens. Duration recording focuses on measuring how long a behavior lasts rather than its frequency. Planned activity check involves observing groups and noting participation levels, which does not specifically target the frequency of an individual behavior. Each of these other methods serves different purposes but does not directly measure the frequency of behaviors as effectively as a frequency count does.
