Change scores from 1,472 older adults (average age 78-year-old; 57% female) and 591 younger adults (average age 53-year-old; 46% female) served by APS during the six months showed reduction of harm using posttest minus pretest. Nonetheless, older adult’s financial abuse harm (pretest=2.2, posttest=1.5) was higher than younger adults’ (pretest=1.5, posttest=1.2), while young adults scored higher in harm on all other types of abuse. Effective interventions differ by age group and by type of abuse, and will be discussed in detail. Results demonstrate the importance to consider vulnerable adult’s age and the etiology of abuse before implementing the services needed to effectively address ANE harm.
