To investigate the relationship between personality, club-drug use and high-risk drug-related behaviour, 360 club-drug users and 303 non-drug users in Hong Kong were assessed on measures of two impulsivity dimensions, reward drive and rash impulsivity, and a related trait of punishment sensitivity. The most frequently used drugs were ketamine, ecstasy, and cannabis, with the majority of participants using two or more drugs on any one occasion. Club-drug users were more rash-impulsive and reward-driven, and less punishment-sensitive than non-drug users (p<0.001). Rash impulsivity, but not reward drive or punishment sensitivity, was significantly (p<0.001) associated with risky drug-related behaviour. There was no association between any personality traits and preferred drug. These findings suggest that, while those who use club drugs are generally more impulsive and less punishment-sensitive, some discrete facets of impulsivity are associated with differing patterns of drug-use behaviour.
为了研究人格、俱乐部药物使用与高风险药物相关行为之间的关系，对香港的360名俱乐部药物使用者和303名非药物使用者进行了评估，测量了两个冲动维度，即奖励驱动和鲁莽冲动，以及一个相关特征惩罚敏感性。最常使用的药物是氯胺酮、摇头丸和大麻，大多数参与者在任何一次使用两种或更多药物。与非药物使用者相比，俱乐部药物使用者更鲁莽冲动、受奖励驱动，且惩罚敏感性更低（p<0.001）。鲁莽冲动而非奖励驱动或惩罚敏感性与高风险药物相关行为显著相关（p<0.001）。任何人格特质与偏好药物之间均无关联。这些发现表明，虽然使用俱乐部药物的人通常更冲动且惩罚敏感性更低，但冲动的一些离散方面与不同的药物使用行为模式相关。
