Assessing Delirium Severity in Dementia: Item Development and Psychometric Validation for a Delirium Severity
Journal of Gerontological Nursing
|August 28, 2024
Summary
Researchers developed 21 items to measure delirium severity in Alzheimer's disease and related dementias (ADRD) patients. This new tool aims to improve clinical assessment and care for ADRD individuals experiencing delirium.
Area of Science:
- Gerontology
- Neurology
- Nursing
Background:
- Delirium severity measurement is crucial for Alzheimer's disease and related dementias (ADRD) patients.
- Currently, no validated instrument exists for this purpose.
Purpose of the Study:
- To generate items for a validated instrument to measure delirium severity in ADRD patients.
- To address the unmet need for a standardized assessment tool.
Main Methods:
- An interdisciplinary expert panel developed items assessing seven domains and 21 subdomains of delirium severity.
- Input was gathered from nursing experts regarding item development and relevance.
Main Results:
- Consensus was reached on 21 items, specifying optimal respondents and look-back periods.
- Nursing experts highlighted the importance of staff education and caregiver information gathering.
Conclusions:
- Developing nuanced items is key for measuring delirium severity in ADRD.
- Engaging nurses is essential for the tool's adoption and clinical relevance.

Dementia is a collective term for cognitive disorders primarily affecting memory, thinking, and reasoning. It is not a specific disease but a syndrome, with Alzheimer's disease being the most common cause, accounting for approximately 60-80% of cases. Other types include vascular dementia, Lewy body dementia, and frontotemporal dementia. Dementia affects millions worldwide, particularly older adults, though it is not a normal part of aging.

Self-report inventories are objective personality assessments that use multiple-choice items or numbered scales, typically ranging from 1 (strongly disagree) to 5 (strongly agree). They are often called Likert scales after Rensis Likert. These inventories are widely used due to their ease of administration and cost-effectiveness. One of the most prominent examples is the Minnesota Multiphasic Personality Inventory (MMPI), initially developed in the 1940s to assess abnormal personality traits.
