The present study examines the association between the ceremonial use of ayahuasca-a decoction combining the Banistereopsis caapi vine and N,N-Dimethyltryptamine-containing plants-and changes in personality traits as conceived by the Five-Factor model (FFM). We also examine the degree to which demographic characteristics, baseline personality, and acute post-ayahuasca experiences affect personality change. Participants recruited from three ayahuasca healing and spiritual centers in South and Central America (N = 256) completed self-report measures of personality at three timepoints (Baseline, Post, 3-month Follow-up). Informant-report measures of the FFM were also obtained (N = 110). Linear mixed models were used to examine changes in personality and the moderation of those changes by covariates. The most pronounced change was a reduction in Neuroticism dz = - 1.00; dz = - .85; dz = - .62), reflected in self- and informant-report data. Moderation of personality change by baseline personality, acute experiences, and purgative experiences was also observed.
本研究考察了仪式上使用 ayahuasca（一种由 Banistereopsis caapi 藤和含有 N,N-二甲基色胺的植物混合而成的汤剂）与五因素模型（FFM）所构想的人格特质变化之间的关联。我们还研究了人口统计学特征、基线人格和急性 ayahuasca 后体验对人格变化的影响程度。参与者来自南美洲和中美洲的三个 ayahuasca 治疗和精神中心（N=256），在三个时间点（基线、后测和 3 个月随访）完成了人格的自我报告测量。还获得了 FFM 的知情者报告测量（N=110）。线性混合模型用于检查人格变化以及协变量对这些变化的调节作用。最明显的变化是神经质降低，dz=−1.00；dz=−0.85；dz=−0.62），自我报告和知情者报告的数据都反映了这一点。还观察到基线人格、急性体验和净化体验对人格变化的调节作用。
