A recent effort to improve the psychometric properties of the Fagerström Tolerance Questionnaire (FTQ) resulted in the revised Fagerström Test for Nicotine Dependence (FTND). We endeavored to replicate and extend findings suggesting the superiority of the FTND by examining the psychometric properties of both instruments, as well as their relationship to self-report and biochemical variables associated with nicotine dependence in 110 smoking clinic participants. Results verified that the FTND represents a modest improvement over the FTQ, however, the need for continued development of self-report measures of nicotine dependence is noted.
