Brief Description: This is a brief 10-item self-report instrument designed to measure smoking behavior across 7 stages. Specifically, items include respondents' self-efficacy and intention to smoke, whether respondent ever smoked, age when smoked one whole cigarette, occurrence of daily smoking, number of days smoked in last 30, and whether a respondent has smoked at least 100 cigarettes.
Target Population: Adolescents, ages 12-18 years
Administrative Issues: This instrument can be administered over the phone.
Scoring Information:

Definition of Categories (also see Susceptibility to Smoking measure)
Committed Never Smoker: Has never smoked a cigarette, even a few puffs, and expresses a strong commitment not to smoke.
Susceptible Never Smoker: Has never smoked a cigarette, even a few puffs, but lacks a strong commitment not to smoke.
Puffer: Has puffed on a cigarette, but denies having smoked a whole cigarette.
Non-Current Experimenter: Reports smoking fewer than 100 cigarettes in lifetime, but has not smoked during the last 30 days.
Current Experimenter: Reports smoking fewer than 100 cigarettes in lifetime, and has smoked during the last 30 days.
Non-Current Established Smoker: Reports smoking at least 100 cigarettes in lifetime, but has not smoked during the last 30 days.
Current Established Smoker: Reports smoking at least 100 cigarettes in lifetime, and has smoked during the last 30 days.

Psychometrics:

Predictive validity (Choi et al, 2001):
<6% Committed Never Smokers progress to Established Smoking over a 3-4 yr period.
˜12% Susceptible Never Smokers and Puffers progress to Establish Smoking over a 3-4 yr period.
Susceptible Never Smokers are 2-3 times more likely to initiate smoking over a 3-4 yr period than are Committed Never Smokers.
˜80% of Current Established Smokers will still be smoking 3-4 yrs later.

Validity data:
Correlations with combined substance use level (tobacco, marijuana, alcohol): Control scale: 0.63, 0.71; Conduct scale: 0.36, 0.54.
Correlation with cigarette smoking: Control scale: 0.56, 0.61; Conduct scale: 0.23, 0.31.

Clinical Utility of Instrument: This instrument can be used to quantify smoking history and current smoking behavior in a standardized way.
Research Applicability: This instrument can be used to quantify smoking history and current smoking behavior in a standardized way.
Copyright, Cost, and Source Issues: No charge for use.
