The use of a sensory room intervention substantially decreased patients' distress and reduced R/S use and aggressive behaviors. Improvements were also found in patient and staff members' sense of safety. No differences in the quality of staff-patient relationships were found based on sensory room use. An increase in the durations of R/S did occur and was attributed to a few patients who were "high users" of R/S. Considerations for continuous program improvement and research are discussed.
