BACKGROUND Generalized anxiety disorder (GAD) is one of the most common mental disorders; however, there is no brief clinical measure for assessing GAD. [...] Key MethodMETHODS A criterion-standard study was performed in 15 primary care clinics in the United States from November 2004 through June 2005. Of a total of 2740 adult patients completing a study questionnaire, 965 patients had a telephone interview with a mental health professional within 1 week.Expand
Validity of the Generalized Anxiety Disorder-7 scale in an acute psychiatric sample.
TLDR
The GAD-7 Scale appears to be a valid measure of generalized anxiety symptoms in this sample, on the basis of good internal consistency, convergent validity and sensitivity to change, but does not perform well as a screener for GAD.

TLDR
The GAD-7 is associated with acceptable specificity and sensitivity for detecting clinically significant anxiety symptoms and may be more efficient than the PARS.

Psychometric Comparison of the Generalized Anxiety Disorder Scale-7 and the Penn State Worry Questionnaire for Measuring Response during Treatment of Generalised Anxiety Disorder
TLDR
Both measures were sensitive to change, although the GAD-7 appeared to be more sensitive and may, therefore, confer some advantages in clinical work.
The 7-item generalized anxiety disorder scale as a tool for measuring generalized anxiety in multiple sclerosis.
TLDR
Findings support the reliability and internal validity of the GAD-7 for use in MS and suggest the need for further anxiety research.

The PHQ-9: validity of a brief depression severity measure.
TLDR
In addition to making criteria-based diagnoses of depressive disorders, the PHQ-9 is also a reliable and valid measure of depression severity, which makes it a useful clinical and research tool.
A self-report scale to help make psychiatric diagnoses: the Psychiatric Diagnostic Screening Questionnaire.
TLDR
The results indicate that most of the PDSQ subscales were able to achieve the goal of good sensitivity, high negative predictive value, and high positive and negative predictive values, so that most noncases on the measure are indeed noncases.
Prevalence of mental disorders in primary care. Implications for screening.
TLDR
Patients returning for follow-up care and, to a lesser extent, those with chronic medical problems appear to be at increased risk of having a mental disorder.
Validation and utility of a self-report version of PRIME-MD: the PHQ primary care study. Primary Care Evaluation of Mental Disorders. Patient Health Questionnaire.
TLDR
The study suggests that the PHQ has diagnostic validity comparable to the original clinician-administered PRIME-MD, and is more efficient to use.
DSM-III-R generalized anxiety disorder in the National Comorbidity Survey.
TLDR
Although lifetime GAD is highly comorbid, the proportion of current GAD that is not accompanied by any other current diagnosis is high enough to indicate that GAD should be considered an independent disorder rather than exclusively a residual or prodrome of other disorders.
Diagnosing ICD-10 Depressive Episodes: Superior Criterion Validity of the Patient Health Questionnaire
TLDR
This is the first comparative study to demonstrate the diagnostic advantage of a particular depression-screening instrument using the ICD-10 diagnostic criteria, and the superior criterion validity of the PHQ is likely attributable to its closer representation of the current concept of depressive disorders.
Rethinking the duration requirement for generalized anxiety disorder: evidence from the National Comorbidity Survey Replication.
TLDR
A large number of people suffer from a GAD-like syndrome with episodes of < 6 months duration and little basis for excluding these people from a diagnosis is found in the associations examined here.
Mental disorders and disability among patients in a primary care group practice.
TLDR
Primary care patients with more than one mental disorder are common and highly disabled, and only patients with major depressive disorder, bipolar disorder, phobias, and substance use disorders had significantly increased disability, as measured by the Sheehan Disability Scale.
Primary care perspectives on generalized anxiety disorder.
TLDR
The collaborative care approach is designed to overcome barriers to effective treatment for generalized anxiety disorder, and the patient is provided with additional educational materials, physicians are supported by physician extenders who provide case-based feedback, follow-up, extra visits, and telephone calls to patients.
