预期影响物质使用的开始和维持。鉴于越来越多的文献致力于处方兴奋剂滥用的增加，对与处方兴奋剂使用相关的预期效应的检查似乎是有必要的。本研究采用修订后的处方兴奋剂期望问卷（PSEQ），并在全国547名参与者中检验其心理测量特性。对46项修订后的问卷（PSEQ-II）进行探索性因素分析，确定了4个因素：认知增强、焦虑与觉醒、社会增强、内疚与依赖。PSEQ-II成功地区分了用户群体（即非用户、娱乐用户、医疗用户、娱乐/医疗用户）。娱乐/医疗使用者的积极期望最强，非使用者的最弱；非使用者的负面预期最强烈，而医疗使用者的负面预期最弱。使用PSEQ-II和对处方兴奋剂相关期望的了解可能有助于预防和治疗处方兴奋剂滥用。
Expectancies influence the initiation and maintenance of substance use. Given the increasing literature devoted to the rise of prescription stimulant misuse, an examination of expectancy effects associated with prescription stimulant use appears warranted. This study employed a revised version of the Prescription Stimulant Expectancy Questionnaire (PSEQ) and examined its psychometric properties in a nationwide sample of 547 participants. An exploratory factor analysis of the 46-item revised questionnaire (PSEQ-II) identified 4 factors: Cognitive Enhancement, Anxiety and Arousal, Social Enhancement, and Guilt and Dependence. The PSEQ-II successfully discriminated among user groups (i.e., nonusers, recreational users, medical users, recreational/medical users). Recreational/medical users held the strongest positive expectancies and nonusers held the weakest; negative expectancies were held most strongly by nonusers and weakest by medical users. Use of the PSEQ-II and knowledge of prescription stimulant-related expectancies may assist in the prevention and treatment of prescription stimulant misuse.
