Add to My Toolkit
Description

Measurement of respondent’s 30-day frequency of use of drugs.

Specific Instructions

The Working Group acknowledges that the following question may gather sensitive information relating to the use of substances or illegal conduct. If the information is released, it might be damaging to an individual’s employability, lead to social stigmatization, or result in other consequences.

For information on obtaining a Certificate of Confidentiality, which helps researchers protect the privacy of human research participants, please go to the National Human Genome Research Institute’s Institutional Review Board website.

Respondents are asked the 30-day frequency question only if they answered "yes" to a drug in the Substances - Lifetime Use measure. For example, if a respondent said he or she had ever used marijuana, he or she will be asked the 30-day question for marijuana. Investigators should refer back to the substance(s) indicated in the Substances - Lifetime Use measure when asking the below question. The drug categories are provided below:

  1. Sedatives or tranquilizers
  2. Painkillers
  3. Marijuana
  4. Cocaine or crack
  5. Stimulants
  6. Club drugs
  7. Hallucinogens
  8. Inhalants or solvents
  9. Heroin
  10. OTHER

Respondents can refer to the National Epidemiologic Survey on Alcohol and Related Conditions-III (NESARC-III) flashcard that provides examples of each.
