Our objective was to compare scores on a smoking questionnaire to a diagnosis of cigarette smoking. As part of follow‐ups in studies of ADHD, we assessed for cigarette smoking using structured interviews and the modified Fagerström Tolerance Questionnaire (mFTQ). Data were obtained from 162 subjects (mean = 19.2 yrs). ROC analysis and kappa coefficients revealed that a cutoff score of 3 on the mFTQ showed the strongest agreement with a full diagnosis of cigarette smoking (kappa = 0.68). Clinicians and researchers using the mFTQ in adolescents and young adults should consider a cutoff score of 3 to be indicative of cigarette smoking.
