General Anxiety Disorder (GAD-7)
Measure severity of anxiety
Creador
Dr. Robert L. Spitzer, MDInstrucciones
The GAD-7 is a screening tool used by health practitioners to determine initial symptom severity and monitor effect of treatment over time and does not replace a clinical assessment and diagnosis.
Ask: How often have you been bothered by the following over the past 2 weeks?
Introduction
Generalized anxiety disorder (GAD) and panic disorder (PD) are among the most common mental disorders in the United States (Locke, Kirst & Shultz, 2015). The Generalized Anxiety Disorder-7 (GAD-7) is a validated diagnostic tool and a symptom severity assessment scale that assists clinicians, typically primary care and mental health settings, with rapid screening for the presence of a clinically significant anxiety disorder, such as GAD, PD, social phobia (SP) & post-traumatic stress disorder (PTSD). GAD-7 can objectively determine initial symptom severity and monitor symptom changes and the effect of treatment over time. Studies suggest 70-90% sensitivity and 80-90% specificity across anxiety disorders. Higher GAD-7 scores correlate with disability and functional impairment in measures to include work productivity and health care utilization (Spitzer, 2006 & Ruiz, 2011). The scale was originally developed and validated based on the DSM-IV criteria. However, since the publication of the DSM-V criteria, the scale remains clinically useful because the differences in GAD diagnostic criteria are minimal.
The Generalized Anxiety Disorder-7 (GAD-7) is a validated diagnostic tool and a symptom severity assessment scale that assists clinicians, typically primary care and mental health settings, with rapid screening for the presence of a clinically significant anxiety disorder, such as GAD, PD, social phobia (SP) & post-traumatic stress disorder (PTSD). GAD-7 is a 7-question assessment. A range of 0-3 points are assigned to each answer. The 8th question assesses global impairment and is not counted in the score (max score of 21 points).
Scoring & Recommendations
The first 7 questions will answer with one of the following:
Answer | Points |
Not at all | 0 |
Several days | 1 |
More than half the days | 2 |
Nearly every day | 3 |
Result | Recommendation | Score |
No anxiety disorder | N/A | < 5 points |
Mild anxiety disorder | Monitor | 5-9 points |
Studies suggest a score ≥ 8 in suspected Panic Disorder, Social Phobia or PTSD may be a moderate anxiety disorder | Need for further evaluation and referral for possible clinically significant condition. | 8-9 points |
Moderate anxiety disorder | Need for further evaluation and referral for possible clinically significant condition. | 10-14 points |
Severe anxiety disorder | Need for further evaluation and referral for possible clinically significant condition. Active treatment is likely warranted. | > 15 points |
Additional Considerations
The PRO-MIS Emotional Distress - Anxiety - Short Form for Adults and the Severity Measure for Generalized Anxiety Disorder - Adult can aid clinical evaluation of generalized anxiety disorders and monitor treatment effectiveness.
The Severity Measure for Panic Disorder - Adult is an assessment scale that can complement the clinical assessment of patients with panic disorder.
In a suspected anxiety disorder, medical conditions with similar presentations ought to be excluded, such as:
Endocrine conditions: Hyperthyroidism, pheochromocytoma, hyperparathyroidism
Cardiopulmonary conditions: Arrhythmia, obstructive pulmonary diseases
Neurologic diseases: Temporal lobe epilepsy, TIA
Other psychiatric disorders: Major depressive disorder, bipolar disorder, other anxiety disorders
Substance abuse withdrawal
Medications: Common ones include albuterol, levothyroxine, decongestants
Lifestyles recommendations that may reduce anxiety-related symptoms include:
Identifying and removing possible triggers
Caffeine: Consider increase sensitivity to caffeine (slow metabolizer) due to genetic polymorphisms in adenosine receptors.
Stimulants: Can include medications, supplements or caffeine products ingested in the evening.
Nicotine
Dietary triggers: Consider mold sensitivity from food or the environment. Foods such as coffee, peanuts and grains can have high levels of mold. Many other food sensitivities or allergies can also play a role. A food journal and an elimination diet may help sort this out.
Stress
Improving sleep quality and quantity
Physical activity
Therapeutic modalities that may reduce anxiety-related symptoms include:
Psychotherapy
Cognitive behavioral therapy
Relaxation therapies
Meditation
Mindfulness-based stress reduction and breathing techniques
Complementary and alternative medicine
Botanicals and supplements (See table 6)
Massage
Sound therapy
Aromatherapy
