Nonmedical prescription stimulant (NPS) use is an important problem among university students. The present studies applied the prototype-willingness model (Gibbons, Gerrard & Lane, 2003) to academic-based NPS use and examined the impact of academic versus health information on university students' NPS use cognitions.
Study 1 used the prototype-willingness model to examine cognitions associated with academic-based willingness to use NPS. In Study 2, participants were randomly assigned to a control condition or to read information on the negative academic or negative health effects of NPS use. Beliefs, willingness, and expectation of engaging in future NPS use, prototypes of users, and perceived vulnerability were assessed.
Students without a prescription for stimulants or a diagnosis of attention deficit hyperactivity disorder (ADHD) participated in each study (Ns = 555; 166). Twenty to thirty per cent reported NPS use, primarily for academic reasons. Controlling for past NPS, alcohol, and marijuana use: friends' NPS use, prototypes, perceived vulnerability, and negative health and positive academic beliefs were associated with willingness to use NPS in Study 1. Study 2 demonstrated that participants in the academic-information condition reported the lowest willingness and expectations as well as the least favourable prototypes of NPS users. Participants in the health-information condition reported the highest perceived vulnerability.
These studies highlight: the utility of using a health model framework to examine NPS cognitions, the importance of examining beliefs about the behaviour, and the potential for academic and health information to reduce risky NPS use cognitions.
非医疗处方兴奋剂(NPS)的使用是大学生群体中的一个重要问题。本研究应用原型意愿模型(Gibbons、Gerrard 和 Lane,2003)来研究基于学术目的的 NPS 使用,并检验学术信息与健康信息对大学生 NPS 使用认知的影响。
研究 1 应用原型意愿模型来检验与基于学术目的使用 NPS 的意愿相关的认知。在研究 2 中,参与者被随机分配到对照组或阅读关于 NPS 使用的负面学术或负面健康影响的信息。评估了信念、意愿和预期、未来使用 NPS 的可能性、使用者的原型以及感知脆弱性。
没有处方兴奋剂或注意力缺陷多动障碍(ADHD)诊断的学生参加了每项研究(N=555;166)。20%至 30%的学生报告使用了 NPS,主要是出于学术目的。控制过去使用 NPS、酒精和大麻的情况:朋友使用 NPS、原型、感知脆弱性以及对健康和学术的积极信念与研究 1 中的使用 NPS 的意愿相关。研究 2 表明,接受学术信息的参与者报告的意愿和期望最低,对 NPS 用户的原型评价最不利。接受健康信息的参与者报告的感知脆弱性最高。
这些研究强调:使用健康模型框架来检验 NPS 认知的有效性,检验对行为的信念的重要性,以及学术和健康信息减少风险 NPS 使用认知的潜力。
