Based on the search results, the performance increase associated with the Hawthorne Effect varies across different studies and contexts. Here are some key findings on the percentage increases reported:
General productivity increase: Data compiled by Levitt & List showed roughly a 10% per year increase in productivity in the groups following the start of the Illumination Studies, regardless of whether they were part of the control or the experimental group1.
Hand hygiene compliance:
In one study, antiseptic hand rub (AHR) compliance increased from 29% to 45% during the overt observation period, which is approximately a 55% increase34.
Another study found that hand sanitizer use increased from 1.48 dispensations per hour to 3.75 dispensations when the sanitizer station was visible to an auditor, representing a 153% increase4.
Antibiotic prescribing: Inappropriate antibiotic prescribing for viral cases was 29% lower when physicians were observed (46% vs. 17%), representing a 63% reduction24.
Patient-reported quality of care: Increased by 13% with direct observation3.
Paramedic reporting: The rate of incomplete paramedic reports declined by 20% after announcement of an upcoming quality-improvement audit4.
Educational research: Clark and Sugrue reported that uncontrolled novelty effects cause on average a 30% of a standard deviation rise (equivalent to a 50–63% score rise) in educational settings, with the effect decaying over time5.
It's important to note that the magnitude of the Hawthorne Effect can vary significantly depending on the specific context, type of behavior being observed, and duration of the study. Some studies found smaller or no effects, while others reported larger increases.
