Public Health

Background:

Elder abuse is a significant public health concern affecting vulnerable populations.
Accurate screening tools are crucial for early identification and intervention.
Previous research has explored various methods for detecting elder abuse.

Purpose of the Study:

To identify reliable and valid questions for detecting elder abuse.
To assess the effectiveness of existing self-report elder abuse screens in a high-risk elderly population.
To describe challenges in completing and interpreting these screens among those with high needs.

Main Methods:

A study involving elders referred to social workers in a community agency.
49 out of 70 approached elders participated.
Telephone questionnaires were administered, with 32 completing a duplicate assessment.

Main Results:

42% of participants were judged to be abused, with 17% having abuse reported and 6% substantiated.
Existing elder abuse screen instruments were not predictive of assessed or reported abuse.
Two specific questions regarding harm and property taking showed significant differences in the abused group.

Conclusions:

Current screening instruments were ineffective in differentiating between abused and non-abused elders in this high-need group.
There is a critical need for improved assessment tools to accurately identify elder abuse.
Findings highlight the limitations of current screens in community-dwelling, high-need elderly individuals.
