The Generalized Anxiety Disorder 7-item scale (GAD-7) is a widely used self-administered diagnostic tool designed to screen for and assess the severity of generalized anxiety disorder (GAD). [1] Comprising seven items, the GAD-7 measures the frequency of anxiety symptoms over the past two weeks, with respondents rating each item on a scale from ...
GAD-7: Content validity: Good Covers seven of the core symptoms for generalized anxiety disorder. [32] Construct validity (e.g., predictive, concurrent, convergent, and discriminant validity) Good Scores correlate with the Beck Anxiety Inventory (r= .72) and the anxiety subscale of the SCL-90 (r=.74). [2] Discriminative validity Too excellent
Using a cut-off of 8 the GAD-7 has a sensitivity of 92% and specificity of 76% for diagnosis generalized anxiety disorder. The following cut-offs correlate with level of anxiety severity: Score 0-4: Minimal Anxiety; Score 5-9: Mild Anxiety; Score 10-14: Moderate Anxiety; Score greater than 15: Severe Anxiety
The GAD-7 is a seven-item anxiety screening instrument developed in 2006 with a similar format to that of the PHQ-9. [20] Total scores range from 0 to 21 with scores of 5, 10, and 15 indicating mild, moderate, and severe anxiety. Unlike the PHQ-9, clinicians use the GAD-7 to assess the severity of anxiety only.
This calculation will yield a comprehensive score in the range of 0 to 56. It has been predetermined that the results of the evaluation can be interpreted as follows. A score of 17 or less indicates mild anxiety severity. A score from 18 to 24 indicates mild to moderate anxiety severity.
Though support exists for using the BAI with high-school students and psychiatric inpatient samples of ages 14 to 18 years, [26] the recently developed diagnostic tool, Beck Youth Inventories, Second Edition, contains an anxiety inventory of 20 questions specifically designed for children and adolescents ages 7 to 18 years old.
The study also showed high internal consistency and high test-retest reliability. The self-report version of the Scale has been extensively tested on the Spanish population, with results high in validity and reliability. They also found significant differences in the scores for some sub-scales (total fear) between males and females. [20]
The Screen for Child Anxiety Related Emotional Disorders (SCARED) is a self-report screening questionnaire for anxiety disorders developed in 1997. [1] The SCARED is intended for youth, 9–18 years old, [1] and their parents to complete in about 10 minutes. [2]
