Summary
A new classification instrument reliably categorizes spontaneous cognitive complaints in elderly patients. This tool aids in understanding the risks associated with these memory concerns.
Area of Science:
- Gerontology
- Cognitive Science
- Medical Informatics
Background:
- Spontaneously reported cognitive complaints lack a classification system, hindering risk assessment.
- Understanding these complaints is crucial for elderly patient care.
Purpose of the Study:
- To develop and validate a practical instrument for classifying spontaneous cognitive complaints.
- To assess the reliability and utility of this new classification system.
Main Methods:
- A modified Delphi technique was used to create a classification system.
- 180 elderly patients provided free reports of cognitive difficulties.
- Three observers classified complaints, with inter-observer agreement assessed using the κ statistic.
Main Results:
- 493 spontaneous complaints were reported by 180 patients.
- The classification instrument achieved high reliability (κ statistic 0.79-0.97).
- Spontaneously reported complaints offered complementary data to the Memory Complaint Questionnaire (MAC-Q).
Conclusions:
- The developed instrument is a practical and reliable tool for classifying spontaneous cognitive complaints.
- Further research is needed to explore the clinical utility of this classification approach.

01:22Self-Report Tests of Personality
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.
01:17Classification of Illness
The meaning of illness is individualized to each person who experiences an alteration in health. In contrast, disease is a medical term indicating a pathological change in the structure and function of the body or mind. It is a condition that has specific symptoms and boundaries.
An illness is a response to a disease in which the person's level of functioning is changed compared with a previous level. The general classification of illness includes acute and chronic.

01:27Diagnostic and Statistical Manual of Mental Disorders (DSM)
The Diagnostic and Statistical Manual of Mental Disorders (DSM) serves as the primary classification system for mental health disorders, providing standardized diagnostic criteria for clinicians and researchers. First published by the American Psychiatric Association (APA) in 1952, the DSM has undergone several revisions to reflect evolving psychiatric understanding. The fifth edition, DSM-5, released in 2013, introduced key updates that expanded diagnostic categories and modified diagnostic...
