Discontinuous Measurement Explained + Free Worksheet

Discontinuous measurement occurs when you divide an observation into intervals and take note of whether a behavior happened during some or all of each interval or at the precise time of observation. Collecting discontinuous data is usually simpler for therapists than collecting continuous data, but keep in mind it may lead to more measurement errors.


Whole Interval Recording – Used to assess continuous behaviors that take place throughout a designated interval. This is useful when behaviors happen so frequently that it is difficult to distinguish one occurrence from another.


Partial Interval Recording – Records behavior occurring at any point during the interval and will be recorded as a positive. A negative would only be scored if the behavior was not observed throughout the interval.


Momentary Time Sampling – You will record a positive if the behavior is observed at the end of the interval. If the behavior is observed at any point during the interval, but stops before it ends, you’ll score it as a negative.
