aNDSS factors: Continuity, which taps the regularity of smoking; drive, which captures craving and withdrawal in abstinence; priority, which reflects the behavioral preference of smoking over other reinforcers; stereotypy, which gets at the invariance or the “sameness” of smoking; and tolerance, which measures the reduced sensitivity to smoking's effects (Shiffman and colleagues; ref. 29). Significant correlations are in bold font.
