This study examined the factorial and criterion validity of the Community Assessment of Psychic Experiences (CAPE). We compared the validity of the original three-dimensional model and a recently proposed multidimensional model, in which positive symptoms are subdivided into the subfactors hallucinations, bizarre experiences, paranoia, grandiosity and magical thinking and negative symptoms are subdivided into social withdrawal, affective flattening and avolition.
Eleven community (n=934) and three patient samples (n=112) were combined and the proposed models were tested using confirmatory factor analysis. Criterion validity was calculated based on self-report measures for depression and paranoia as well as observer-based ratings for positive and negative symptoms.
The multidimensional model showed better relative quality (AIC, BIC) than the original three-dimensional model of the CAPE, but both models showed acceptable absolute model-fit (RMSEA, SRMR). The criterion validity was good for the positive symptom scales and negative symptom subfactors social withdrawal and affective flattening.
Factorial validity was found for the three-dimensional and multidimensional model for the CAPE. The multidimensional model, however, shows better comparative fit and promising results in regard to criterion validity. Thus, we recommend a hierarchical multidimensional structure of positive and negative symptoms for future use of the CAPE.
本研究检验了精神体验社区评估量表（CAPE）的因子效度和效标效度。我们比较了原始三维模型与最近提出的多维模型的效度，在多维模型中，阳性症状被细分为幻觉、怪异体验、偏执、夸大观念和神奇思维等子因子，阴性症状被细分为社交退缩、情感平淡和意志缺乏。
合并了11个社区样本（n = 934）和3个患者样本（n = 112），并使用验证性因子分析对提出的模型进行检验。效标效度基于抑郁和偏执的自我报告测量以及基于观察者的阳性和阴性症状评分来计算。
多维模型显示出比CAPE原始三维模型更好的相对质量（AIC、BIC），但两个模型都显示出可接受的绝对模型拟合度（RMSEA、SRMR）。阳性症状量表以及阴性症状子因子社交退缩和情感平淡的效标效度良好。
发现CAPE的三维模型和多维模型具有因子效度。然而，多维模型在比较拟合方面表现更好，并且在效标效度方面有很有前景的结果。因此，我们建议未来使用CAPE时采用阳性和阴性症状的分层多维结构。
