Lifetime nicotine dependence, i.e. the intensity of physical addiction to nicotine in the period of heaviest smoking, was assessed in adult Lifelines participants using the Fagerström Test for Nicotine Dependence (FTND) (section: mental health).
Note that Lifelines also assessed participants' smoking & tobacco use in general.
The Fagerström Tolerance Questionnaire was developed by Karl-Olov Fagerström. This instrument was modified to the Fagerström Test for Nicotine Dependence by Todd Heatherton, et al. in 19911). The FTND is copyrighted by Taylor and Francis Ltd., but may be reproduced without permission, as available from the source reference.
The FTND was designed to provide an ordinal measure of nicotine dependence related to cigarette smoking. In the clinic, the Fagerström test may be used by the physician to document indications for prescribing medication for nicotine withdrawal.
The FTND contains six items that evaluate the quantity of cigarette consumption, the compulsion to use, and dependence (items FTND03-08). Items were scored from 0 to 1 (yes/no items) or from 0 to 3 (multiple-choice items). The scores are summed to yield a total score of 0-10. The higher the total Fagerström score, the more intense is the patient's physical dependence on nicotine.
