Clawback incentives refer to a framing effect applied to rewards where participants are intended to experience losing the reward via noncompliance rather than accruing it for successful performance of the behavior.
For example, a hypertension management program may credit its participants $200 at the beginning of the month, and reduce or "claw back" the amount by $3 each time the patient does not take their medication. The alternative would be starting the month at zero or the previous ballance and adding $3 each time the patient takes the medication.
