Objective: We investigated: i) the reliability and validity of a Brazilian version of the Community Assessment of Psychic Experiences (CAPE), developed to detect and characterize psychotic experiences in the general population; and ii) the association between psychotic experiences, childhood adversity, and cannabis use in a population-based sample. Methods: We performed factorial analyses and generalized linear models with CAPE scores as the dependent variable in a sample composed of 217 first-episode psychosis patients, 104 unaffected biological siblings, and 319 non-psychotic population-based participants. Results: After removing seven items from its positive dimension and two items from its negative dimension, a 33-item Brazilian version of the CAPE showed acceptable adjustment indices (confirmatory fit index = 0.895; goodness of fit index = 0.822; parsimony goodness of fit index = 0.761; root mean square error of approximation [RMSEA] = 0.055, p [RMSEA ≤ 0.05] = 0.04) and internal consistency in all its dimensions (> 0.70). Childhood adversity was associated with higher scores in all three dimensions, as well as with total score. Lifetime cannabis use was associated with higher scores only in the positive dimension. Conclusion: The proposed Brazilian version of the CAPE corroborates the tridimensional approach for assessing psychosis-proneness, and the frequency and severity of psychotic manifestations are distributed as a spectrum in the general population.

在巴西样本中验证葡萄牙语版本的心理体验社区评估和精神病体验特征

目标：我们调查了：i) 巴西版本的心理体验社区评估 (CAPE) 的可靠性和有效性，该版本旨在检测和表征一般人群的精神病体验；ii) 基于人群的样本中精神病经历、童年逆境和大麻使用之间的关联。方法：我们在由 217 名首发精神病患者、104 名未受影响的生物学兄弟姐妹和 319 名非精神病人群参与者组成的样本中，以 CAPE 评分为因变量进行因子分析和广义线性模型。结果：在从正面维度去除 7 个项目和从负面维度去除两个项目后，33 项巴西版本的 CAPE 显示出可接受的调整指数（验证拟合指数 = 0.895；拟合优度指数 = 0。822; 简约拟合优度指数 = 0.761；近似均方根误差 [RMSEA] = 0.055，p [RMSEA ≤ 0.05] = 0.04) 及其所有维度的内部一致性 (> 0.70)。童年逆境与所有三个维度以及总分的得分较高有关。终生使用大麻仅在积极方面与更高的分数相关。结论：拟议的巴西版 CAPE 证实了评估精神病倾向的立体方法，精神病表现的频率和严重程度在一般人群中以频谱的形式分布。童年逆境与所有三个维度以及总分的得分较高有关。终生使用大麻仅在积极方面与更高的分数相关。结论：拟议的巴西版 CAPE 证实了评估精神病倾向的立体方法，精神病表现的频率和严重程度在一般人群中以频谱的形式分布。童年逆境与所有三个维度以及总分的得分较高有关。终生使用大麻仅在积极方面与更高的分数相关。结论：拟议的巴西版 CAPE 证实了评估精神病倾向的立体方法，精神病表现的频率和严重程度在一般人群中以频谱的形式分布。
