How might data be collected for this target response?Partial Interval/Whole Interval recording. I would pop in throughout the day and check to see if data is being collected.
Identify several interventions that might help improve response rates. Place them in order with the least-restrictive at the top so that the interventions may be introduced systematically, adding more restrictive / less favorable interventions after the outcomes of less restrictive options have been measured.

-visual reminder/poster of reminding to collect data
-send out daily/email to collect data
-observe staff collect data during supervision
-write up staff that are not collecting data
