We aimed to perform a cluster analysis to investigate the group structure of a combination of psychotic-like experiences (PLEs) and self-disturbances in a non-clinical sample. Non-clinical adults (n = 677) were assessed with the Community Assessment of Psychic Experiences (CAPE), the Davos Assessment of Cognitive Biases Scale (DACOBS) and the Inventory of Psychotic-Like Anomalous Self-Experiences (IPASE). Cluster analysis was conducted based on the positive and negative dimension of CAPE and a total score of IPASE. Four distinct groups were revealed by the cluster analysis. The High Profile group had the highest means, and the Low Profile had the lowest scores of positive and negative subscales of the CAPE and IPASE. The Positive Profile group had a significantly higher level of self-disturbances (in 'Cognition', 'Consciousnesses and 'Somatization' dimensions) from participants with the 'Negative Profile'. The High Profile group had more cognitive biases (i.e., inadequate cognitive inference about internal and external events) related to psychosis as assessed with DACOBS, had the highest means on each IPASE subscale and had a higher level of emotional distress. A combination of high level of PLEs and self-disturbances may capture the highest risk of psychosis in the general population associated with cognitive biases characteristic for psychosis.
我们旨在进行聚类分析，以调查非临床样本中精神病样体验（PLEs）和自我困扰的组合的群体结构。非临床成年人（n=677）接受了心理体验社区评估（CAPE）、认知偏差评估量表（DACOBS）和精神病样异常自我体验清单（IPASE）的评估。聚类分析基于 CAPE 的阳性和阴性维度以及 IPASE 的总分进行。聚类分析揭示了四个不同的群体。高特征组的平均值最高，低特征组的 CAPE 和 IPASE 的阳性和阴性分量表的得分最低。阳性特征组的自我困扰程度（在“认知”、“意识”和“躯体化”维度）显著高于“负面特征”组的参与者。高特征组的认知偏差（即对内部和外部事件的不适当认知推断）与 DACOBS 评估的精神病有关，在每个 IPASE 分量表上的平均值最高，并且情绪困扰程度更高。高水平的 PLEs 和自我困扰的组合可能会捕捉到与精神病特征相关的认知偏差相关的一般人群中最高的精神病风险。
