Geriatric Depression Scale as a community screening instrument for elderly Chinese immigrants

Area of Science:

• Geriatric Psychiatry
• Cross-cultural Psychology
• Mental Health Screening

Background:

• Depression is a significant mental health concern in elderly populations, particularly among Chinese-American immigrants.
• Existing screening tools may require cultural adaptation for diverse demographic groups.

Purpose of the Study:

• To develop and validate a culturally appropriate Chinese version of the Geriatric Depression Scale Short Form (GDS-SF).
• To establish a reliable and accessible screening tool for depression in elderly Chinese immigrants.

Main Methods:

• Development of a Chinese-language Geriatric Depression Scale (GDS-LF and GDS-SF).
• Internal consistency analysis of the GDS-LF and initial GDS-SF.
• Factor analysis to revise the GDS-SF for improved psychometric properties.

Main Results:

• The original Chinese GDS-LF demonstrated high internal consistency.
• The initial Chinese GDS-SF lacked sufficient internal consistency.
• A revised Chinese GDS-SF, developed through factor analysis, exhibited strong internal consistency.

Conclusions:

• The revised Chinese GDS-SF is a psychometrically sound and user-friendly instrument.
• This validated scale is suitable for community-based depression screening among elderly Chinese immigrants.
• The study highlights the importance of culturally adapted mental health assessment tools.
