The Abrams geriatric self-neglect scale: introduction, validation and psychometric properties.

Area of Science:

• Gerontology
• Psychometrics
• Geriatric Psychiatry

Background:

• Self-neglect is a poorly defined condition in the elderly, leading to adverse health outcomes.
• Limited research exists due to the lack of specific and inclusive measurement tools.
• The Abrams Geriatric Self-Neglect Scale (AGSS) was developed to address this gap.

Purpose of the Study:

• To establish the psychometric properties of the Abrams Geriatric Self-Neglect Scale (AGSS).
• To validate the AGSS as a quantitative instrument for measuring self-neglect in older adults.

Main Methods:

• Analysis of data from a 2007 case-control study involving 71 cognitively intact older self-neglectors.
• Validation of the AGSS against expert consensus criteria and geriatric psychiatrist judgment.
• Examination of scale domain frequencies by source (Subject, Observer, Overall Impression) and estimation of internal consistency.

Main Results:

• The AGSS demonstrated good internal consistency, with Observer responses yielding the highest reliability (alpha/omega: 0.758/0.765).
• Subject and Observer scores showed moderate association (0.578).
• The Observer and Overall Impression subscales showed good classification of self-neglect, while the Subject subscale was fair.

Conclusions:

• The AGSS accurately classifies and quantifies self-neglect when validated against established criteria.
• The scale's multiple information sources (Subject, Observer, Overall Impression) offer flexibility for researchers and clinicians.
• Lower consistency in Subject responses may reflect self-neglectors' tendency to deny symptoms.
