We first compared LTAA to the combined NAC group (a 2 × 2 design with Group and Gender as fixed effects and the four SSS subscales as the dependent variables). The multivariate analysis showed a significant gender effect (Wilkes λ4,93 = 6.16, p < 0.0001; men having greater sensation seeking than women), but no significant group (Wilkes λ4,93 = 1.025, p = 0.399) or group by gender effect (Wilkes λ4,93 = 0.799, p = 0.529).
