Protocol 2: Tobacco - Smoking Status (Adult Protocol)   #030602
Protocol Release Date   

February 6, 2009

Description of Protocol   

Measurement to determine respondent’s smoking status.

Specific Instructions   

The respondents will answer a question about whether he or she has smoked at least 100 cigarettes (approximately five packs of cigarettes) in his or her lifetime. If he or she indicates that he or she has smoked at least 100 cigarettes, the respondent is queried about whether he or she now smokes every day or some days, or whether he or she is a former smoker. Lastly, if the respondent is a Current Some-Day or Former Smoker, the respondent is asked if he or she has ever smoked every day for at least 6 months.

Protocol Text   

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

Note to interviewer: Based on responses provided to earlier questions, the respondent may also be asked Questions 2, 3, and 4 (see interviewer notes before these questions).


1. Have you smoked at least 100 cigarettes in your entire life?
(Note to interviewer: 100 CIGARETTES = APPROXIMATELY 5 PACKS)

If Question 1 is "Yes" then respondent is asked:

2. Do you now smoke cigarettes every day, some days, or not at all?

Every day

If Question 1 is "Yes" and Question 2 is "Some days" (Current Some-Day Smoker) or if Question 1 is "Yes" and Question 2 is "Not at all" (Former Smoker), then respondent is asked:

3. Have you EVER smoked cigarettes EVERY DAY for at least 6 months?

Interpreting responses to assess smoking status of adults:
  • If answer to Question 1 is "No," then respondent is a "Never Smoker."

  • If answer to Question 1 is "Yes" and answer to Question 2 is "Every day," then respondent is a "Current Every-Day Smoker."

  • If answer to Question 1 is "Yes" and answer to Question 2 is "Some days," then respondent is a "Current Some-Day Smoker."

  • If answer to Question 1 is "Yes" and answer to Question 2 is "Not at all," then respondent is a "Former Smoker."

  • Question 3 allows further classification of Current Some-Day and Former Smokers into those who smoked every day in the past from those who have not done so. The former would be indicating heavier past exposure.

Selection Rationale   

The Tobacco Use Supplement to the Current Population Survey (TUS-CPS) is an adult-focused survey, and its questions are comparable to the CDC’s National Center for Health Statistics - National Health Interview Survey (NHIS) and National Health and Nutrition Examination Survey (NHANES) and NCI’s Health Information National Trends Survey (HINTS).

Language of Source

English, Available in other languages

Participant from Source

≥18 years of age*

* If the study population consists of adolescents and young adults (12-24 years) with the intention of studying onset of risky behaviors, the investigator may wish to use the adolescent profile. If the study population primarily consists of adults (≥18 years), emphasizing established smoking and/or cessation, the investigator should use the adult profile.

Personnel and Training Required   

Interviewer must be trained and found to be competent to conduct personal interviews with individuals from the general population. The interviewer should be trained to prompt respondents further if a "don’t know" response is provided.

Equipment Needs   

While the source instrument was developed to be administered by computer, the PhenX Working Group acknowledges these questions can be administered in a noncomputerized format.
