Objectives There is growing evidence that delusional-like experiences (DLE) are associated with common mental disorders. In particular, a National Mental Health Survey conducted in Australia during 2007 reported an association between DLE and both anxiety disorder and major depressive disorder (MDD). However, the previous study did not examine this association with respect to subtypes of anxiety disorder nor with severity of MDD. The aim of this study was to examine the associations between DLE… 
Delusion-like experiences in older people with anxiety disorders
TLDR
In this cross-sectional study, self-reported delusion-like experiences occurred at increased prevalence among community-residing older persons with anxiety disorder.
Service Use for Mental Health Problems in People with Delusional-Like Experiences: A Nationwide Population Based Survey
TLDR
DLEs are common in the general population, and individuals with DLEs have an increased rate of accessing services for their mental health needs, and Individuals endorsing both DLETs and increased help-seeking may identify a group of vulnerable people who have increased risk of developing psychotic illnesses later in life.
A study in the general population about sadness to disentangle the continuum from well-being to depressive disorders.
TLDR
Sadness validates the depressive continuum hypothesis, since it is more frequent in the general population than MDD itself and at the same time shares with MDD the same sociodemographic and clinical correlates.
Psychotic experiences in the context of mood and anxiety disorders and their associations with health outcomes among people of color in the United States.
TLDR
Mental health practitioners serving people of color who have mood/anxiety disorders should routinely screen for psychotic experiences, which may suggest health problems and disabilities that warrant integrated healthcare.
The co-occurrence of common mental and physical disorders within Australian families: A national population-based study
TLDR
Those who had a CIDI diagnosis of major depressive disorders, anxiety disorders, or drug or alcohol abuse/dependence were significantly more likely to have first-degree relatives with the same diagnosis as the respondent.
Risk and functional significance of psychotic experiences among individuals with depression in 44 low- and middle-income countries
TLDR
Having coexisting PEs and depression was associated with a higher risk for observable illness behavior and a significant decline in health status in the cognition, interpersonal activities and sleep/energy domains, compared with those with depression alone.
Psychotic Experiences in the General Population: A Cross-National Analysis Based on 31,261 Respondents From 18 Countries.
TLDR
The epidemiologic features of PEs are more nuanced than previously thought and research is needed that focuses on similarities and differences in the predictors of the onset, course, and consequences of distinct PEs.
Self-reported psychosis-like experiences in patients with mood disorders
TLDR
Several, state- and trait-related factors may underlie self-reported PEs among mood disorder patients, including cognitive-perceptual distortions of SPD; distrustfulness, identity disturbance, dissociative and affective symptoms of BPD; and cognitive biases related to depressive or manic symptoms.
Features of borderline personality disorder as a mediator of the relation between childhood traumatic experiences and psychosis-like experiences in patients with mood disorder
TLDR
Self-reported cognitive-perceptual symptoms of BPD fully mediate, while affective, behavioural and interpersonal symptoms only partially mediate the relationships between CEs and PEs.
The Bidirectional Associations Between Psychotic Experiences and DSM-IV Mental Disorders.
TLDR
Data show that most mental disorders are associated with an elevated risk of subsequent psychotic experiences, and further investigation of the underlying factors accounting for these time-order relationships may shed light on the etiology of psychotic experiences.

TLDR
While DLE have traditionally been associated with psychotic disorders, the results suggest that they are associated with non-specific psychological distress in otherwise-well individuals.
The Association between Physical Health and Delusional-Like Experiences: A General Population Study
TLDR
Delusional-like experiences are common in the Australian community, and are associated with selected chronic physical disorders and with impaired hearing, and the direction of causality between these variables warrants closer research scrutiny.

TLDR
The association between family history of a wide range of mental disorders and DLE in an Australian general population survey suggests that familial factors associated with DLE may be shared with aWide range of common mental disorders.
Psychotic-like experiences in major depression and anxiety disorders: a population-based survey in young adults.
TLDR
While psychotic-like experiences are usually associated with psychotic disorders, individuals with depression and anxiety are also more likely to report these symptoms compared with well individuals.
Correlates of Delusion-Like Experiences in a Non-Psychotic Community Sample
TLDR
The association with a family history of mental disorders provides clues to the mechanisms underlying the profile of delusion-like experience in non-psychotic individuals.
Psychotic-like experiences and correlation with distress and depressive symptoms in a community sample of adolescents and young adults
TLDR
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.
Psychotic-like experiences in the general community: the correlates of CIDI psychosis screen items in an Australian sample
TLDR
Many of the correlates of endorsement of psychosis-screen items are also associated with psychosis, and unravelling the factors that contribute to this broader non-clinical phenotype will aid the understanding of psychosis.
The association between delusional-like experiences and suicidal thoughts and behaviour
TLDR
DLEs are common in the general population and appear to be independently associated with suicidal thoughts and behaviour, and may provide a marker of vulnerability to suicide, and thus could be of value in future suicide prevention research.
Association between psychotic experiences and depression in a clinical sample over 6 months
TLDR
Depression was assessed as a continuous measure using the Mood and Anxiety Symptom Questionnaire (MASQ) and categorically according to DSM-IV diagnosis of mood disorder and PLEs reduced in conjunction with an improvement in depression level and with remission of diagnosis of Mood disorder.
The association between delusional-like experiences, and tobacco, alcohol or cannabis use: a nationwide population-based survey
TLDR
The findings linking alcohol and tobacco use and DLE suggest that the influence of these substances on psychosis-related outcomes warrants closer scrutiny in longitudinal prospective studies.
