Psychotic-like experiences (PLE) are sub-threshold, non-clinical forms of psychosis which can place an individual at greater risk of development of a psychotic disorder. Subtypes of PLE have also been shown to exist (bizarre experiences, persecutory ideation, perceptual abnormalities and magical thinking). Perceived stress relates to how two individuals may deal with the same objectively stressful event in different ways. The objective of our study was to investigate the extent to which perceived stress is associated with PLE in a community sample of adolescents, whether certain subtypes of PLE correlate more with perceived stress than others and to explore the role of depression with these associations.
A total of 655 students completed the community assessment of psychic experiences (CAPE) and perceived stress scale (PSS). Pearson's correlation was used to investigate the relationship between PSS and CAPE and also between perceived stress and the four subtypes of PLE. Regression then explored the effect of perceived stress on PLE when accounting for depressive symptomatology.
Positive correlation was found between PSS and total CAPE (r = 0.405, P = 0.000). Positive significant correlation was also found between PSS and each subtype of PLE, with persecutory ideation correlating the strongest and magical thinking the least. Perceived stress was significantly associated with PLE even after adjusting for depression.
We recommend that more regular screening of perceived stress in adolescent populations could lead to earlier recognition of PLE. Early treatment has shown to reduce rates of transition to psychosis, and so could benefit our adolescent community in the future.
类精神病体验（PLE）是阈下的、非临床形式的精神病，可使个体处于发展为精神病障碍的更高风险中。PLE 也存在亚型（奇异体验、被害妄想、知觉异常和神奇思维）。感知到的压力与两个人如何以不同的方式应对相同的客观压力事件有关。我们研究的目的是调查感知压力与青少年社区样本中的 PLE 之间的关联程度，特定的 PLE 亚型是否比其他亚型与感知压力更相关，并探讨抑郁与这些关联的关系。
共有 655 名学生完成了心理体验社区评估（CAPE）和感知压力量表（PSS）。Pearson 相关用于调查 PSS 和 CAPE 之间以及感知压力和 PLE 的四个亚型之间的关系。然后回归探索在考虑抑郁症状的情况下，感知压力对 PLE 的影响。
发现 PSS 与总 CAPE 之间呈正相关（r = 0.405，P = 0.000）。PSS 与 PLE 的每种亚型之间也发现了正显著相关，其中被害妄想的相关性最强，神奇思维的相关性最弱。即使在调整抑郁症状后，感知压力仍与 PLE 显著相关。
我们建议，在青少年人群中更频繁地筛查感知压力，可能会更早地发现 PLE。早期治疗已显示可降低向精神病过渡的比率，因此将来可能会使我们的青少年社区受益。
