Generalized Anxiety Disorder 7


somatization

The GAD-7 is commonly used as a measure of general anxiety symptoms across various settings and populations.

What is the GAD-7?

The GAD-7 is a seven-question self-report scale that asks participants to rate their level of anxiety over the past two weeks using the following responses: 0 = Not at all, 1 = Several days, 2 = More than half the days, 3 = Nearly every day. The total score is the sum of the seven questions.

How are scores determined?

Scores are determined by adding up all seven responses and dividing by 7 (the number of questions) which gives you your average score for those two weeks. The cutoff points for clinical anxiety disorders range from an average total score between 10–15 on the GAD-7 scale.

What does this questionnaire measure?

The GAD-7 is a measure of anxiety symptoms, but it was derived from the DSM-IV criteria for diagnoses related to Generalized Anxiety Disorder (GAD). The questionnaire is valid and reliable in different populations and settings. It has also been shown to be effective as a screening tool for anxiety disorders.

Are there any factors that might affect the GAD-7 results?

Although it is not clear, some researchers suggest that cultural factors may contribute to differences in how individuals respond to the questionnaire. However, this is not true across all studies and researchers.

The GAD-7 should not be used as a diagnostic tool. It can only be used to screen for symptoms of anxiety and other related disorders.

How long does it take to administer?

The GAD-7 takes about five minutes to complete. If the participant requires more clarification on what each question means, as is the case in many studies, it can take up to 15 minutes.

The GAD-7 is a self-report questionnaire so the test must be administered in a private setting and participants should not have access to notes or any other materials while completing the survey.

What are some strengths and limitations of the GAD-7?

Strength: It is quick, simple to score, and easy to use. In addition, it is a valid and reliable measure.

Limitations: Although it is an effective screening tool for anxiety disorders, the GAD-7 should not be used as a diagnostic tool. It can only be used to screen for symptoms of anxiety and other related disorders.

How is the GAD-7 scored?

To score the GAD-7, add up all seven questions and divide that number by 7 (the number of questions) which gives you your average score for those two weeks.

GAD-7 Clinical Scoring:

10 – 14 = Mild Anxiety (symptoms of anxiety present, but minimal impact on daily life)

15+ = Moderate to Severe Anxiety (symptoms of anxiety are impacting daily life and/or maybe indicative of a clinical disorder)

GAD-7 Non-Clinical Scoring:

0 – 9 = No or Minimal Anxiety (no symptoms of anxiety present)

10 – 14 = Mild Anxiety (symptoms of anxiety may be present, but minimal impact on daily life)

15+ = Moderate to Severe Anxiety (symptoms of anxiety are impacting daily life and/or maybe indicative of a clinical disorder)
