namePhenX - substance - 30D frequency protocol 031301
descriptionMeasurement of respondent's 30-day frequency of use of drugs. 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. If the respondent answered "no" to ever using cocaine, the 30-day question for cocaine is skipped. The source survey asked these questions of respondents aged 12 years and older. However, the PhenX Working Group recommends that these be asked only after the screener question, which is asked only of respondents aged 18 years and older.
