Description

The MOOD DISORDER QUESTIONNAIRE (MDQ) is a self-report tool used to assess the likelihood of bipolar disorder. It consists of a series of questions that explore mood symptoms, as well as the frequency and duration of manic or hypomanic episodes.

Data Analysis and Use

Data analysis from the MDQ includes:

Scoring: Participants respond to questions that are scored, with results indicating the likelihood of bipolar disorder.

Statistical Analysis: Descriptive statistics are used to evaluate results, along with comparative analyses between different populations.

Validation: The MDQ is compared with other diagnostic scales to confirm its reliability.

Objective

The objective of the MDQ is to identify individuals who may suffer from bipolar disorder, providing a tool that can be used for diagnosis and guiding treatment.

Calibration

The calibration of the MDQ includes the process of adjusting the tool for use in various populations. This involves:

Cross-Cultural Studies: Testing the MDQ in different cultural and social populations.

Reliability Assessment: Using Cronbach’s alpha to evaluate the internal consistency of the questions.

Validity Testing: Examining the MDQ’s ability to detect the actual presence of bipolar symptoms.
