A potential caveat to our findings is the possibility that our modification of the SSS (removal of all items directly addressing drug or alcohol use) decreased the Scale’s sensitivity to detect differences between LTAA and NAC that do, in fact, exist. We reject this possibility for two reasons. First, our modified SSS was sensitive enough to detect increased sensation seeking in TxN compared to both NAC and LTAA. Second, the modified scales are more than sensitive enough to detect the higher sensation seeking scores in men versus women. In the literature cited in the introduction (Andrucci, Archer et al. 1989; Earleywine and Finn 1991; Conrod, Castellanos et al. 2008; Croissant, Demmel et al. 2008), gender differences on the SSS are of comparable or less magnitude than are differences between alcoholics and non-alcoholics.
