The Fagerstrom Test for Nicotine Dependence was designed to provide an ordinal measure of nicotine dependence related to cigarette smoking. It contains six items that evaluate the quantity of cigarette consumption, the compulsion to use, and dependence. It is useful as a screen for nicotine dependence and as a severity rating that can be used for treatment planning and prognostic judgments.
The Modified Fagerstrom Tolerance Questionnaire (mFTQ; Prokhorov et al., 1998) is an adapted version of a scale originally designed to assess behavioral indicators of physical dependence on nicotine among adult smokers (FTQ). It includes a modified set of adult symptoms for adolescents to address graded levels of smoking behavior, avoidance of the physiological effects of nicotine deprivation, and perceived difficulty refraining when prevented from smoking. It has been shown to predict continued smoking, quantity and frequencey of tobacco use, and shorter periods of abstinence from smoking over time.
The FTND is sometimes also called the FTCD -- Fagerstrom Test for Cigarette Dependence.
