开发OAV问卷是为了整合意识改变状态（ASC）的研究。它测量ASC的三个主要维度和一个次要维度，这些维度假设在ASC归纳方法中是不变的。OAV评定量表已经使用了20多年，并在国际上广泛应用于研究领域，但其因子结构从未通过结构方程建模技术进行测试，其心理测量特性也从未在实验诱发ASC的大样本中进行过检验。本研究对裸盖菇素（n = 327）、氯胺酮（n = 162）和MDMA （n = 102）诱导ASC的OAV样本进行了心理测量评估，这些样本来自43项实验研究的汇总数据。采用验证性因子分析、探索性结构方程模型、层次项目聚类（ICLUST）和多指标多原因（MIMIC）模型检验因子结构。即使放宽对非目标因子负荷和残差相关性的零约束，最初提出的模型也不能很好地拟合数据。此外，ICLUST建议“海洋无界”和“幻想重构”因素可以在建构层次的高水平上结合起来。然而，由于这些因素是多维的，我们提取并检查了11个新的低阶因素。MIMIC模型表明，这些因素在药物、环境、问卷版本和性别之间具有高度的测量不变性。新因子具有更好的同质性，令人满意的信度，判别效度和收敛效度，并能很好地区分三种药物组。OAV的原始量表被证明是多维结构。构建了11个新的低阶量表，并证明了它们具有理想的心理测量特性。新的低阶量表很可能更适合于评估药物诱导的ASC。
The OAV questionnaire has been developed to integrate research on altered states of consciousness (ASC). It measures three primary and one secondary dimensions of ASC that are hypothesized to be invariant across ASC induction methods. The OAV rating scale has been in use for more than 20 years and applied internationally in a broad range of research fields, yet its factorial structure has never been tested by structural equation modeling techniques and its psychometric properties have never been examined in large samples of experimentally induced ASC. The present study conducted a psychometric evaluation of the OAV in a sample of psilocybin (n = 327), ketamine (n = 162), and MDMA (n = 102) induced ASC that was obtained by pooling data from 43 experimental studies. The factorial structure was examined by confirmatory factor analysis, exploratory structural equation modeling, hierarchical item clustering (ICLUST), and multiple indicators multiple causes (MIMIC) modeling. The originally proposed model did not fit the data well even if zero-constraints on non-target factor loadings and residual correlations were relaxed. Furthermore, ICLUST suggested that the “oceanic boundlessness” and “visionary restructuralization” factors could be combined on a high level of the construct hierarchy. However, because these factors were multidimensional, we extracted and examined 11 new lower order factors. MIMIC modeling indicated that these factors were highly measurement invariant across drugs, settings, questionnaire versions, and sexes. The new factors were also demonstrated to have improved homogeneities, satisfactory reliabilities, discriminant and convergent validities, and to differentiate well among the three drug groups. The original scales of the OAV were shown to be multidimensional constructs. Eleven new lower order scales were constructed and demonstrated to have desirable psychometric properties. The new lower order scales are most likely better suited to assess drug induced ASC.
