Symptom Questionnaire anxiety and depression scales: reliability and validity

Area of Science:

• Gerontology
• Psychological Assessment
• Clinical Psychology

Background:

• Existing psychological state measures are often developed for younger populations.
• This limits the availability of valid and reliable instruments for assessing elders.
• Geriatric populations require specialized assessment tools for accurate mental health evaluation.

Purpose of the Study:

• To evaluate the reliability and validity of the Symptom Questionnaire's anxiety and depression scales for use in an elderly population.
• To determine if a shortened version of the Symptom Questionnaire is suitable for geriatric assessment.
• To address the challenge of selecting appropriate psychological measures for older adults.

Main Methods:

• The study focused on elders hospitalized with an acute episode of a chronic condition.
• Reliability and validity of the Symptom Questionnaire's anxiety and depression scales were assessed.
• A short version of the Symptom Questionnaire was compared to the full instrument.

Main Results:

• The short version of the Symptom Questionnaire, comprising the depression and anxiety scales, demonstrated good reliability and validity in elders.
• Findings indicate the shortened instrument is a suitable measure for this demographic.
• Minimal differences were observed between data collected using the short and full versions.

Conclusions:

• A condensed Symptom Questionnaire is a reliable and valid tool for assessing anxiety and depression in hospitalized elders.
• This shortened measure provides a practical and effective option for geriatric psychological assessment.
• The findings support the use of this instrument in clinical settings for older adults.
