Studies investigating risk-related behavior in relation to new psychoactive substance (NPS) use are sparse. The current study investigated characteristics of NPS users by comparing risk-related behavior of NPS users to that of illicit drugs (ID) users and licit substances users and non-users (NLC) users.
In this cross-sectional study we included 528 individuals across an age range of 18-72years. Using a web-based questionnaire we collected self-report data on substance use, sensation seeking, impulsivity, peer substance use and risk perception of substance use.
NPS and ID users had a higher level of sensation seeking compared to NLC users (NPS users: p<0.001; ID users: p<0.001). NPS users (p<0.001), but not ID users (p=0.16), had increased levels of impulsivity compared to NLC users. NPS users had significantly higher scores for sensation seeking (F=51.52, p<0.001) and impulsivity (F=6.15, p=0.01) compared to ID users. Additionally, NPS users had significantly more peers who use substances compared to ID and NLC users. Also, NPS and ID users had lower risk perception for most substances than NLC users. NPS users had lower risk perception for most substances than ID users.
The findings highlight that NPS users show substantial more risk-related behavior than both ID and NLC users. Therefore, NPS users might be considered as a distinctive group of substance users that need another approach in terms of prevention.
关于新精神活性物质（NPS）使用相关风险行为的研究较少。本研究通过比较NPS使用者与非法药物（ID）使用者、合法物质使用者及非使用者（NLC）的风险相关行为，调查了NPS使用者的特征。
在这项横断面研究中，我们纳入了528名年龄在18至72岁之间的个体。通过基于网络的问卷，我们收集了关于物质使用、感觉寻求、冲动性、同伴物质使用及物质使用风险认知的自我报告数据。
与NLC使用者相比，NPS和ID使用者的感觉寻求水平更高（NPS使用者：p<0.001；ID使用者：p<0.001）。与NLC使用者相比，NPS使用者的冲动性水平有所增加（p<0.001），但ID使用者没有（p=0.16）。与ID使用者相比，NPS使用者在感觉寻求（F=51.52，p<0.001）和冲动性（F=6.15，p=0.01）方面的得分显著更高。此外，与ID和NLC使用者相比，NPS使用者有更多使用物质的同伴。而且，与NLC使用者相比，NPS和ID使用者对大多数物质的风险认知较低。与ID使用者相比，NPS使用者对大多数物质的风险认知较低。
研究结果表明，NPS使用者表现出比ID和NLC使用者更多的风险相关行为。因此，NPS使用者可能被视为一类独特的物质使用者群体，在预防方面需要采取不同的方法。
