Description

The Cambridge Mental Disorders of the Elderly Examination (CAMDEX-28) is a tool designed to assess mental disorders and cognitive impairments in elderly individuals. The CAMDEX-28 includes 28 questions that cover various aspects of mental health and memory disorders, such as depression, dementia, and other cognitive dysfunctions.

Data Analysis and Usage

The analysis of data from the CAMDEX-28 involves quantitative and qualitative techniques to evaluate mental disorders and cognitive functions in elderly individuals. Key analysis processes include:
Means and Standard Deviations: Calculation of means and standard deviations for each question or for the subscales of the scale.
Reliability: Assessment of the internal consistency of the tool through the Cronbach’s alpha coefficient to ensure the reliability of the results.
Correlation Examination: Examination of correlations between responses to various questions or subscales to understand relationships between different aspects of mental disorders.
Factor Identification: Use of factor analyses to identify key factors contributing to mental disorders, if necessary.

Purpose

The main purpose of the CAMDEX-28 is to provide a reliable tool for assessing mental disorders and cognitive impairments in elderly individuals. It is used for:
Research Purposes: Studying the relationship between mental disorders and other variables, as well as their impact on the daily lives of elderly individuals.
Clinical Assessment: Evaluating the mental health of elderly individuals and designing interventions to support them.
Diagnostic Purposes: Assisting in the diagnosis of mental disorders such as depression and dementia.

Calibration

The calibration of the CAMDEX-28 involves analyzing the data obtained from using the scale:
Internal Consistency Assessment: Calculation of the tool’s reliability using Cronbach’s alpha to ensure the consistency of responses.
Comparative Analysis: Comparison of results with data from other relevant studies to confirm the validity and reliability of the tool.
