The Organic Brain Syndrome (OBS) scale: a systematic review

Area of Science:

• Geriatric Medicine
• Neuropsychology
• Psychometrics

Background:

• The Organic Brain Syndrome (OBS) Scale was designed to evaluate disturbances in awareness, orientation, and emotional/behavioral symptoms in elderly patients with organic mental diseases.
• These conditions include delirium, dementia, and other neurocognitive disorders.

Purpose of the Study:

• To systematically examine the Organic Brain Syndrome (OBS) Scale based on the Scientific Advisory Committee (SAC) criteria.
• To assess the scale's relevance and suitability for diverse clinical settings.

Main Methods:

• A systematic literature search and analysis of 30 papers concerning the OBS Scale were conducted.
• The evaluation adhered to the eight criteria and guidelines set forth by the SAC.

Main Results:

• The OBS Scale demonstrates strengths in conceptual and measurement models, reliability, validity, responsiveness, interpretability, and administrative aspects.
• Areas identified for further evaluation include specific reliability measures and cross-cultural/linguistic adaptations.

Conclusions:

• The OBS Scale is a clinically valuable tool for describing and monitoring patients with acute confusional states and dementia.
• Additional research is warranted to support its wider use and adaptation for various populations.
