CAGE questionnaire for detection of substance use
The CAGE questionnaire is a widely-used screening tool that was originally developed to detect alcohol abuse, but has been adapted to assess other substance abuse.25,26 The omission of substance abuse from diagnostic consideration can have a major effect on quality of care, because substance abuse can be the underlying cause of other diseases. Therefore, routine administration of this instrument in clinical practice can lead to better understanding and monitoring of patient health.27
Similar to other instruments, CAGE is free and available online.27 It contains 4 simple questions, with 1 point is assigned to each positive answer.
Have you ever:
1. Felt the need to cut down on your drinking or drug use?
2. Have people annoyed you by criticizing your drinking or drug use?
3. Have you felt bad or guilty about your drinking or drug use?
4. Have you ever had a drink or used drugs first thing in the morning to steady your nerves or to get rid of a hangover (eye-opener)?
The simple mnemonic CAGE makes the questions easy to remember and to administer in a clinical setting. CAGE has demonstrated validity, with one study determining that CAGE scores ≥2 had a specificity and sensitivity of 76% and 93%, respectively, for identifying excessive drinking, and a specificity and sensitivity of 77% and 91%, respectively, for identifying alcohol abuse.28
Columbia Suicide Severity Rating Scale (C-SSRS)
C-SSRS was developed by researchers at Columbia University to assess the severity of and track changes over time in suicidal ideation and behavior. C-SSRS is 2 pages and takes only a few minutes to administer; however, it also may be completed as a self-report measure. The questions are phrased for use in an interview format, and clinicians are encouraged to receive training prior to its administration, although specific training in mental health is not required.
The “Lifetime/Recent” version allows practitioners to gather lifetime history of suicidality as well as any recent suicidal ideation and/or behavior, whereas the “Since Last Visit” version of the scale assesses suicidality in patients who have completed at least 1 Lifetime/Recent C-SSRS assessment. A truncated, 6-item “Screener” version is typically used in emergency situations. A risk assessment can be added to either the Full or Screener version to summarize the answers from C-SSRS and document risk and protective factors.29
Several studies have found C-SSRS to be reliable and valid for identifying suicide risk in children and adults.30,31USA Today reported that an individual exhibiting even a single behavior identified by the scale is 8 to 10 times more likely to complete suicide.32 In addition, the C-SSRS has helped reduce the suicide rate 65% in one of the largest providers of community-based behavioral health care in the United States.32
Using scales to augment care
Each of the scales described in this article can easily be incorporated into clinical practice and offers psychiatrists important clinical information that may have been missed or not addressed in the initial clinical interview. This information can be used to follow progression of symptoms and effectiveness of treatment. Although rating scales should never be used alone to establish a diagnosis or clinical treatment plan, they can and should be used to augment information from the clinician’s assessment and follow-up interviews.5
