Abstract

Several studies have used a network analysis to recognize the dynamics and determinants of psychotic-like experiences (PLEs) in community samples. Their synthesis has not been provided so far. A systematic review of studies using a network analysis to assess the dynamics of PLEs in community samples was performed. Altogether, 27 studies were included. The overall percentage ranks of centrality metrics for PLEs were 23.5% for strength (20 studies), 26.0% for betweenness (5 studies), 29.7% for closeness (6 studies), 26.9% for expected influence (7 studies), and 29.1% for bridge expected influence (3 studies). Included studies covered three topics: phenomenology of PLEs and associated symptom domains (14 studies), exposure to stress and PLEs (7 studies), and PLEs with respect to suicide-related outcomes (6 studies). Several other symptom domains were directly connected to PLEs. A total of 6 studies investigated PLEs with respect to childhood trauma (CT) history. These studies demonstrated that PLEs are directly connected to CT history (4 studies) or a cumulative measure of environmental exposures (1 study). Moreover, CT was found to moderate the association of PLEs with other symptom domains (1 study). Two studies that revealed direct connections of CT with PLEs also found potential mediating effects of cognitive biases and general psychopathology. PLEs were also directly connected to suicide-related outcomes across all studies included within this topic. The findings imply that PLEs are transdiagnostic phenomena that do not represent the most central domain of psychopathology in community samples. Their occurrence might be associated with CT and suicide risk.

使用网络分析来评估社区样本中类似精神病体验的动态研究的系统回顾。
一些研究使用网络分析来识别社区样本中类精神病经历(ple)的动态和决定因素。到目前为止,还没有提供它们的合成方法。对利用网络分析评估社区样本中生物多样性动态的研究进行了系统回顾。总共纳入了27项研究。强度(20项研究)为23.5%,中间性(5项研究)为26.0%,接近性(6项研究)为29.7%,预期影响(7项研究)为26.9%,桥梁预期影响(3项研究)为29.1%。纳入的研究涵盖了三个主题:ple的现象学和相关症状域(14项研究),暴露于压力和ple(7项研究),以及ple与自杀相关结果(6项研究)。其他几个症状域与ple直接相关。共有6项研究调查了ple与儿童创伤(CT)史的关系。这些研究表明,ple与CT病史(4项研究)或环境暴露的累积测量(1项研究)直接相关。此外,CT被发现可以缓和ple与其他症状域的关联(1项研究)。两项研究揭示了CT与ple的直接联系,也发现了认知偏差和一般精神病理学的潜在中介作用。在本主题的所有研究中,ple也与自杀相关的结果直接相关。研究结果表明,ple是一种跨诊断现象,并不代表社区样本中精神病理学的最核心领域。它们的发生可能与CT和自杀风险有关。
