About Anxiety Disorder Diagnostic Questionnaire (ADDQ)
The Anxiety Disorder Diagnostic Questionnaire (ADDQ) is a structured self-report tool developed to aid in the diagnosis of anxiety disorders. Created by Norton and Robinson in 2010, the ADDQ is designed to assess a range of anxiety symptoms and provide a reliable diagnostic framework for clinicians and researchers.
Purpose of the Tool
The ADDQ serves multiple purposes:
- To help identify and differentiate various anxiety disorders in clinical and research settings.
- To standardize the assessment of anxiety symptoms, making it easier to diagnose specific anxiety disorders.
- To facilitate effective treatment planning by providing a clear symptom profile of anxiety disorders.
Description of Tool
Anxiety disorders are a leading cause of mental health concerns globally, often requiring structured and accurate tools for diagnosis and assessment. The Anxiety Disorder Diagnostic Questionnaire was developed to fill a gap in available diagnostic tools by providing a comprehensive yet simple self-report format that can quickly identify the presence and severity of anxiety symptoms. Norton and Robinson’s work in 2010 focused on creating a reliable measure specifically suited to differentiating anxiety subtypes, such as generalized anxiety disorder, panic disorder, and social anxiety disorder.
The ADDQ consists of a series of questions covering symptoms associated with different types of anxiety disorders. Respondents rate the frequency and severity of their symptoms, with each response contributing to an overall score that aids in identifying specific anxiety disorders. The structured nature of the ADDQ allows it to pinpoint specific diagnostic criteria for multiple anxiety disorders, which assists clinicians in forming precise diagnoses and treatment plans.
Psychometric Properties
- Reliability: The ADDQ has demonstrated high internal consistency and strong test-retest reliability, indicating it is a stable and dependable measure for anxiety assessment.
- Validity: Validity studies show the ADDQ accurately distinguishes between individuals with and without anxiety disorders. It is also correlated with other widely accepted anxiety measures, confirming its concurrent and construct validity.
Age Group
The ADDQ is intended for adults aged 18 and above, and it is particularly valuable in clinical settings where detailed assessment of anxiety symptoms is required for diagnosis and treatment planning.
