Evaluate anxiety symptoms using the most common and validated scale – based on diagnostic criteria described in DSM-IV.

The GAD-7 is a brief measure of symptoms of anxiety, based on diagnostic criteria described in DSM-IV. It consists of seven questions and is calculated by assigning scores of 0, 1, 2, and 3, to the response categories of “not at all”, “several days”, “more than half the days,” and “nearly every day,” respectively. GAD-7 total score for the seven items ranges from 0 to 21. Scores of 5, 10, and 15 represent cutpoints for mild, moderate, and severe anxiety, respectively.

Though designed primarily as a screening and severity measure for generalized anxiety disorder, the GAD-7 also has moderately good operating characteristics for three other common anxiety disorders – panic disorder, social anxiety disorder, and post-traumatic stress disorder. When screening for anxiety disorders, a recommended cutpoint for further evaluation is a score of 10 or greater.

“Have you documented your use of the ADHD DSM-IV criteria when making a diagnosis of Adult ADHD?”

The Adult ADHD Self-Report Scale (ASRS v1.1) and scoring system were developed in conjunction with the World Health Organization (WHO) and the Workgroup on Adult ADHD.

As a healthcare professional, you can use the ASRS v1.1 as a tool to help screen for adult ADHD patients. Insights gained through this screening may suggest the need for a more in-depth clinician interview. The questions in the ASRS v1.1 are consistent with DSM-IV criteria and address the manifestations of ADHD symptoms in adults. Content of the questionnaire also reflects the importance that DSM-IV places on symptoms, impairments, and history for a correct diagnosis.

The screener takes less than 5 minutes to complete and can provide supplemental information that is critical to the diagnostic process.

“Because of its ease of use, short time to administer, high sensitivity, and moderate specificity, the ASRS-V1.1 is an effective adult ADHD screening to guide further evaluations for ADHD.” (J Am Board Fam Med 2012;25:847–853.)
