Screening the elderly in the community for psychiatric disorder

Area of Science:

• Geriatric Medicine
• Psychiatry
• Psychometric Evaluation

Background:

• Screening for mental health conditions in the elderly is crucial for timely intervention.
• The General Health Questionnaire (GHQ) is a widely used screening tool, but its utility in older populations requires validation.

Purpose of the Study:

• To evaluate the 30-item GHQ as a screening instrument for mental health in community-dwelling individuals aged 70 and older.
• To assess the GHQ's sensitivity and specificity in this demographic.
• To determine the GHQ's effectiveness in detecting specific mental health disorders, such as generalized anxiety, and its potential role alongside other cognitive assessments.

Main Methods:

• A community-based study involving individuals aged 70 years and older.
• Administration of the 30-item General Health Questionnaire (GHQ).
• Analysis of GHQ performance metrics, including sensitivity and specificity, and comparison with diagnostic criteria for anxiety disorders and dementia.

Main Results:

• The 30-item GHQ demonstrated acceptable sensitivity (70%) and specificity (84%) for screening mental health issues in individuals aged 70+.
• The GHQ showed limitations in detecting chronic, generalized anxiety disorders in this age group, similar to findings in younger populations.
• The study suggests the GHQ is most effective when used in conjunction with the Mini-Mental State Examination (MMSE) for screening dementia.

Conclusions:

• The 30-item GHQ is a viable screening tool for general mental health in older adults (70+).
• The GHQ's utility for diagnosing generalized anxiety disorders in the elderly is limited.
• Combining the GHQ with the MMSE enhances the screening process for dementia in the elderly population.
