Background:

The Anxiety Symptoms Questionnaire (ASQ) is a brief self-report measure designed for clinical anxiety assessment.
Its utility requires validation across diverse populations, including those with anxiety disorders, depression, and healthy controls.

Purpose of the Study:

To evaluate the reliability and validity of the Anxiety Symptoms Questionnaire (ASQ).
To assess ASQ performance in patients diagnosed with anxiety disorders or depression, non-clinical subjects, and college students.

Main Methods:

Administered ASQ and other anxiety/depression measures to 240 outpatients and 111 non-clinical controls.
Utilized factor analysis, correlation, and logistic regression for reliability and validity assessment.
Assessed test-retest reliability via re-administration of ASQ to a subset after 4 weeks.

Main Results:

Factor analysis confirmed ASQ measures a single underlying dimension of anxiety.
ASQ demonstrated strong internal consistency and test-retest reliability.
ASQ total scores effectively differentiated anxiety disorder patients from controls, outperforming the Hamilton Anxiety Scale.

Conclusions:

The Anxiety Symptoms Questionnaire (ASQ) is a valid and reliable self-report instrument for anxiety assessment.
ASQ is effective for screening and evaluating anxiety symptoms in psychiatric and academic environments.
