TLDR
It is suggested that infrequent psychotic-like experiences are unlikely to be a specific risk factor for onset of a psychotic disorder in community samples, and may represent expressions of underlying vulnerability to psychotic disorder, but Magical Thinking may be a normal personality variant.Abstract:
Objective: Studies conducted in community samples suggest that psychotic-like experiences are common in the general population, leading to suggestions that they are either variations of normal personality or are different expressions of underlying vulnerability to psychotic disorder. Different types of psychotic symptoms may exist, some being normal variants and some having implications for mental health and functioning. The aim of the present study was to determine if different subtypes of psychotic-like experiences could be identified in a community sample of adolescents and to investigate if particular subtypes were more likely to be associated with psychosocial difficulties, that is, distress, depression and poor functioning, than other subtypes.Method: Eight hundred and seventy-five Year 10 students from 34 schools participated in a cross-sectional survey that measured psychotic-like experiences using the Community Assessment of Psychic Experiences; depression using the Centre for Epidemiologic Studi...read more

TL;DR: Compelling support is found for the phenomenological and temporal continuity between PE and psychotic disorder and for the fundamental proposition that this relationship is probabilistic.

TL;DR: The ARMS patients are characterized by high prevalence of anxiety and depressive disorders in addition to their attenuated psychotic symptoms, which may reflect core emotional dysregulation processes and delusional mood in prodromal psychosis.

TL;DR: The ultra high-risk patients are at long-term risk for psychotic disorder, with the highest risk within the first 2 years of entry into the service, but individuals continued to be at risk up to 10 years after initial referral.

TL;DR: Different subtypes of PLEs seem to have different psychopathological meaning and may therefore indicate different levels of risk of severe psychiatric disorders, which suggests it is misleading to define PSEs as a homogenous entity.
