目的应用项目反应理论(IRT)和多指标-多原因(MIMIC)方法对迷幻剂使用障碍(HUDS)诊断问题、不同项目功能(DIF)诊断问题和潜在性HUD预测因素的项目级心理测量学特性进行评估。方法研究数据来源于2004-2006年全国药物使用与健康调查。分析基于过去一年中年龄在12-17岁之间的1548名迷幻剂使用者。药物的使用和症状通过音频计算机辅助的自我访谈方法进行评估。结果使用和依赖的标准被经验地排列成一个严重程度的单一连续体。所有滥用标准都显示了IRT定义的HUD连续体的中到高度严重程度，而依赖标准涵盖了从最低(耐受性和花费的时间)到最高(服用更多药物和无法减少)严重程度的更大范围。迷幻剂使用者的年龄、性别、种族/民族和摇头丸使用状况表明存在DIF。对DIF进行调整后，摇头丸使用者(与非摇头丸迷幻剂使用者相比)、女性(与男性相比)和白人(与西班牙裔美国人相比)表现出更高的HUD几率。结论从经验上讲，迷幻剂滥用和依赖的症状并不反映青少年中的两种独立情况。应进一步审查与女孩和白人使用迷幻剂有关的趋势和问题，以便为设计有效的、适合性别和文化敏感的预防方案提供信息。
AIMThis study applied both item response theory (IRT) and multiple indicators–multiple causes (MIMIC) methods to evaluate item-level psychometric properties of diagnostic questions for hallucinogen use disorders (HUDs), differential item functioning (DIF), and predictors of latent HUD.METHODSData were drawn from 2004–2006 National Surveys on Drug Use and Health. Analyses were based on 1548 past-year hallucinogen users aged 12–17years. Substance use and symptoms were assessed by audio computer-assisted self-interviewing methods.RESULTSAbuse and dependence criteria empirically were arrayed along a single continuum of severity. All abuse criteria indicated middle-to-high severity on the IRT-defined HUD continuum, while dependence criteria captured a wider range from the lowest (tolerance and time spent) to the highest (taking larger amounts and inability to cut down) severity levels. There was indication of DIF by hallucinogen users' age, gender, race/ethnicity, and ecstasy use status. Adjusting for DIF, ecstasy users (vs. non-ecstasy hallucinogen users), females (vs. males), and whites (vs. Hispanics) exhibited increased odds of HUD.CONCLUSIONSSymptoms of hallucinogen abuse and dependence empirically do not reflect two discrete conditions in adolescents. Trends and problems related to hallucinogen use among girls and whites should be examined further to inform the designs of effective gender-appropriate and culturally sensitive prevention programs.
