Abstract
ObjectivesWe aimed to investigate latent classes of psychotic‐like experiences (PLEs) and self‐disturbances (SD) and to explore mutual overlapping between derived subgroups. Further, our goal was to investigate class membership relationship with an exposure to childhood trauma and different psychopathological factors such as cognitive biases, depression, insomnia, psychiatric diagnosis and lifetime suicidality.MethodsParticipants consist of 3167 non‐clinical adults. We performed two latent class analyses (LCA), for PLEs and SD separately, to identify subgroups of individuals with different profiles on PLEs and SD. Associations between psychopathological factors and latent class membership were examined using multinomial logistic regression analysis.ResultsLCA produced 5 classes within SD and 3 classes within PLEs. Class of the highest endorsement of SD showed 53% overlap with class of the highest endorsement of PLEs. The highest risk of belonging to High Class for both SD and PLEs was associated in particular with depression, cognitive biases and insomnia. Trauma emerged as a significant predictor only for PLEs classes.ConclusionsOur findings confirm that high PLEs and SD co‐occur and are concentrated in a relatively small number of individuals, at least in the general population. Their combination may capture the highest risk of psychosis in the general population.
Highlights
The growing interest and evidence for the hypothesis of the psychosis continuum causes more frequent search for risk factors among people from non-clinical samples
Not much is known about the mutual relationship of psychotic-like experiences (PLEs) and SD and how, taken together, they relate to known psychological risk factors for psychosis
This provides the opportunity to study the mechanisms of psychosis amongst people with a high frequency of PLEs, but who are not afflicted by psychotic disorders
Summary
The growing interest and evidence for the hypothesis of the psychosis continuum causes more frequent search for risk factors among people from non-clinical samples. Recent advances in the field have shown that both PLEs and SD among non-clinical individuals are related to important risk factors including exposures to traumatic-life events (Andorko et al, 2018; Gaweda et al, 2018a), cognitive biases There is a wider phenotype of psychosis in the general population and PLEs are one of its behavioral expressions (van Os, 2016). This provides the opportunity to study the mechanisms of psychosis amongst people with a high frequency of PLEs, but who are not afflicted by psychotic disorders
