酒精的主观体验是多维度的，并表现出广泛的个体间差异。最近的努力试图建立一个更清晰的理解主观酒精的反应，通过确定核心结构来自多个测量instruments. ESTA本研究的目的是评估这种方法的时间稳定性概念化酒精的主观经验，在连续的酒精管理在同一individuals.MethodsHealthy适度饮酒者（n= 104）完成了六个实验会话，三个用酒精（0.8g/kg），三个用非酒精对照饮料。参与者在饮用饮料之前和之后多次使用标准化问卷报告主观情绪和药物效果。我们探讨了潜在的结构的主观反应，所有的酒精管理使用探索性因素分析，然后测试测量不变性在连续三个管理使用多组验证性因素analysis.ResultsExploratory因素分析对酒精的反应在所有管理产生四个因素代表“积极的情绪”，“镇静”，“刺激/欣快”，和“药物的影响和敦促”。一个验证性的因素分析表明，可接受的tumerural和度量的不变性和温和的标量invariation.ConclusionsIn这项研究中，我们证明了时间的稳定性的基本结构的主观酒精反应来自因子分析。这些研究结果加强了这种方法的效用概念化的主观酒精反应，特别是用于前瞻性和纵向酒精挑战研究有关的主观反应，酒精使用障碍的风险。
RationaleAlcohol subjective experiences are multi-dimensional and demonstrate wide inter-individual variability. Recent efforts have sought to establish a clearer understanding of subjective alcohol responses by identifying core constructs derived from multiple measurement instruments.ObjectiveThe aim of this study was to evaluate the temporal stability of this approach to conceptualizing alcohol subjective experiences across successive alcohol administrations in the same individuals.MethodsHealthy moderate alcohol drinkers (n= 104) completed six experimental sessions each, three with alcohol (0.8 g/kg), and three with a non-alcoholic control beverage. Participants reported subjective mood and drug effects using standardized questionnaires before and at repeated times after beverage consumption. We explored the underlying latent structure of subjective responses for all alcohol administrations using exploratory factor analysis and then tested measurement invariance over the three successive administrations using multi-group confirmatory factor analyses.ResultsExploratory factor analyses on responses to alcohol across all administrations yielded four factors representing “Positive mood,” “Sedation,” “Stimulation/Euphoria,” and “Drug effects and Urges.” A confirmatory factor analysis on the separate administrations indicated acceptable configural and metric invariance and moderate scalar invariance.ConclusionsIn this study, we demonstrate temporal stability of the underlying constructs of subjective alcohol responses derived from factor analysis. These findings strengthen the utility of this approach to conceptualizing subjective alcohol responses especially for use in prospective and longitudinal alcohol challenge studies relating subjective response to alcohol use disorder risk.
