Objective: The National Elder Mistreatment Study (NEMS) found that 5.2% of community older adults experienced financial abuse, and 4.6% experienced emotional mistreatment in the past year. Unfortunately, the majority of abuse was not reported to the authorities. This study investigated reasons for non-reporting. Method: In all, 774 NEMS participants were surveyed 8 years later via telephone to assess past-year financial and emotional mistreatment, perpetrator status, and whether any of these episodes were reported to authorities. Results: In total, 87.5% of financial abuse by family, friends, or acquaintances was not reported versus 33% of that perpetrated by strangers; for emotional mistreatment, 89.9% of that perpetrated by family, friends, and acquaintances was not reported, compared with 83.3% by strangers. Reasons for non-reporting of emotional abuse centered largely around with “not wanting publicity” and “not wanting to get the perpetrator in trouble,” while no consistent reason emerged for failure to report stranger-perpetrated mistreatment.
