    GAD-7 (General Anxiety Disorder-7)

    Measures severity of anxiety.

    When to Use
    Pearls/Pitfalls
    Why Use

    Rapid screening for the presence of a clinically significant anxiety disorder (GAD, PD, SP & PTSD), especially in outpatient settings.

    • The GAD-7 is useful in primary care and mental health settings as a screening tool and symptom severity measure for the four most common anxiety disorders (Generalized Anxiety Disorder, Panic Disorder, Social Phobia and PostTraumatic Stress Disorder).
    • It is 70-90% sensitive and 80-90% specific across disorders / cutoffs (see Evidence section for more).
    • Higher GAD-7 scores correlate with disability and functional impairment (in measures such as work productivity and health care utilization). (Spitzer RL 2006) (Ruiz MA 2011)
    • The last item “How difficult have these problems made it for you to do your work, take care of things at home, or get along with other people?” - although not used in the calculation - is a good indicator of the patient’s global impairment and can be used to track treatment response.

    Objectively determine initial symptoms severity and monitor symptom changes/effect of treatment over time.

    Ask the patient: how often have they been bothered by the following over the past 2 weeks?

    Management

    Scores ≥10: Further assessment (including diagnostic interview and mental status examination) and/or referral to a mental health professional recommended.

    *For Panic Disorder, Social Phobia, & PTSD, cutoff score of 8 may be used for optimal sensitivity/specificity (see Evidence section).

    Critical Actions

    • This tool should be used for screening and monitoring symptom severity and cannot replace a clinical assessment and diagnosis.
    • Do not forget to rule out medical causes of anxiety before diagnosing an anxiety disorder (for example, EKG for arrhythmias, TSH for thyroid disease).
