Reliability and validity of the Glover-Nilsson smoking behavioral questionnaire

OBJECTIVES To establish reliability/validity of the Glover-Nilsson Smoking Behavioral Questionnaire (GN-SBQ). METHODS The GN-SBQ and the Fagerstrom Test for Nicotine Dependence (FTND) were completed by 100 smokers. The number of cigarettes smoked, smoking duration, and craving were obtained. RESULTS The GN-SBQ was internally consistent (Cronbach α = .82), temporally stable (r = .86), and uncorrelated with FTND. There was a significant main effect for craving, F(3, 73) = 14.68, p < .001; and the GN-SBQ was a significant predictor of craving levels (β = .476, p < .001). CONCLUSIONS The GN-SBQ shows promise as a tool for distinguishing behavioral from physical nicotine dependence.
