|Brief Description:||This is a brief 6-item instrument designed to measure nicotine dependence. Items were generated from the Fagerstrom Tolerance Questionnaire (Fagerstrom, 1978; Fagerstrom and Schneider, 1989) and the Nicotine Dependence Syndrome Scale (Shiffman et al., 1995).|
|Target Population:||Adolescents, current smokers, average age 15 years, grades 6-11. The scale was validated using data from the American Legacy Longitudinal Tobacco Use Reduction Study (ALLTURS, N = 4,904).|
|Administrative Issues:||Instrument can be self-administered in a classroom setting.|
|Scoring Information:||Factor analysis indicated that the items form a single factor. Two items with factor loadings < .50 were dropped from the scale, leaving six items.
Scores for two items (How soon after you wake up do you usually smoke your first cigarette [on weekends/on weekdays]?) were averaged. The average for those two items is then summed with scores on the remaining 4 items.
The NDSA has a range of 0 to 16.5.
|Psychometrics:||Internal Consistency: Cronbach's alpha: 0.82.
Validity (correlation coefficients):
Days smoked in the past 30 days: r = 0.66.
Cigarettes smoked per day on days smoked: r = 0.61.
Number of quit attempts: r = 0.10.
Length of quit attempt: r = -0.22.
Correlation with salivary cotinine: r = 0.57a.
|Clinical Utility of Instrument:||This instrument was developed primarily for survey research purposes; clinical utility is limited. Cut-offs for classifying respondents as dependent or not dependent have not been established.|
|Research Applicability:||This instrument adds to a limited literature studying the measurement of nicotine dependence in adolescent populations. It was designed to be a short self-report measure of an adolescent's the level of dependence on a continuous scale. It can be useful for survey research and for evaluating research models of smoking behavior.|
