Factorial structure of the Hungarian version of Oxford-Liverpool Inventory of Feelings and Experiences and its applicability on the schizophrenia-schizotypy continuum

The aim of our study was to test the original four factor structure of Oxford-Liverpool Inventory of Feelings and Experiences (O-LIFE) short version (Mason et al., 2005) on a healthy sample (Study 1). Our further aim was to examine if positive, negative and disorganised symptoms of schizophrenia are positively correlated with schizotypy dimensions in patients with schizophrenia spectrum disorders, as well as the difference of patients and matched healthy controls regarding schizotypy (Study 2). In Study 1 the Hungarian translation of O-LIFE short version was administered to an undergraduate sample (N=406). In Study 2 Scales for Assessment of Negative Symptoms (SANS, Andreasen, 1983), Scales for Assessment of Positive Symptoms (SAPS, Andreasen, 1983) and O-LIFE short version were administered to inpatients (N=65) and outpatients (N=37) with a schizophrenia spectrum diagnosis as well as matched controls (N=29). Factor analysis supported the four-factor model yielding positive, negative and disorganised schizotypy, as well as impulsivity factors. SAPS was found to correlate positively with positive schizotypy (r=.338 p<.001), SANS was found to correlate positively with negative schizotypy (r=.231, p<.05). No correlation was found between disorganised symptoms and Cognitive Disorganisation. Controls differed from patients on each dimensions of schizotypy.

The measurement invariance of schizotypy in Europe

The short version of the Oxford-Liverpool Inventory of Feelings and Experiences (sO-LIFE) is a widely used measure assessing schizotypy. There is limited information, however, on how sO-LIFE scores compare across different countries. The main goal of the present study is to test the measurement invariance of the sO-LIFE scores in a large sample of non-clinical adolescents and young adults from four European countries (UK, Switzerland, Italy, and Spain). The scores were obtained from validated versions of the sO-LIFE in their respective languages. The sample comprised 4190 participants (M=20.87 years; SD=3.71 years). The study of the internal structure, using confirmatory factor analysis, revealed that both three (i.e., positive schizotypy, cognitive disorganisation, and introvertive anhedonia) and four-factor (i.e., positive schizotypy, cognitive disorganisation, introvertive anhedonia, and impulsive nonconformity) models fitted the data moderately well. Multi-group confirmatory factor analysis showed that the three-factor model had partial strong measurement invariance across countries. Eight items were non-invariant across samples. Significant statistical differences in the mean scores of the s-OLIFE were found by country. Reliability scores, estimated with Ordinal alpha ranged from 0.75 to 0.87. Using the Item Response Theory framework, the sO-LIFE provides more accuracy information at the medium and high end of the latent trait. The current results show further evidence in support of the psychometric proprieties of the sO-LIFE, provide new information about the cross-cultural equivalence of schizotypy and support the use of this measure to screen for psychotic-like features and liability to psychosis in general population samples from different European countries.

The Oxford–Liverpool Inventory of Feelings and Experiences short version: Further validation

The main goal of the present study was to examine the dimensional structure and gather new sources of validity evidence of the Oxford–Liverpool Inventory of Feelings and Experiences short version (sO-LIFE) in a large sample of young adults. The sample was made up of 1002 college students (M=21.11years; SD=3.92). The study of the internal structure, using confirmatory factor analysis, revealed that both three and four-factor solutions fitted well to the data. Furthermore, new measurement models, such us Exploratory Structural Equation Modelling (ESEM), showed that the hypothetical three-factor model displayed better goodness-of-fit indices than the other competing models tested. Multi-group ESEM showed that the three-factor model had partially strong measurement invariance across gender. The reliability of the scores ranged from 0.78 to 0.87. The sO-LIFE scores showed good convergent and discriminant validity with other measures of schizotypal personality traits and hedonic capacity. These results provide new information about the factor structure of schizotypy in non-clinical samples and support the use of sO-LIFE as a measure of schizotypy in nonclinical samples.

Schizotypal Traits are Associated with Poorer Executive Functioning in Healthy Adults.

Previous research has shown mild forms of the neurocognitive impairments seen in schizophrenia among healthy individuals exhibiting high schizotypal traits. This study aimed to explore associations between schizotypy and cognitive performance in an adult community sample. Ninety-five females and 79 males completed the Oxford–Liverpool Inventory of Feelings and Experiences (O-LIFE), which measures four separable aspects of schizotypy: cognitive disorganization, unusual experiences, introvertive anhedonia, and impulsive non-conformity. Subsequently, participants were administered a neurocognitive battery incorporating measures of executive skills including inhibition, cognitive flexibility, reasoning, and problem solving along with measures of attention and processing speed and both verbal and spatial working memory. In line with predictions, the current study found that higher scores on the subscales of unusual experiences, cognitive disorganization, and impulsive non-conformity related to worse performance on a measure of inhibition. Additionally, as introvertive anhedonia increased, both attention and processing speed and reasoning and problem-solving performance became more impaired. In conclusion, this study extends schizotypy literature by examining the subscales of the O-LIFE, and enables inferences to be drawn in relation to cognitive impairment in schizophrenia.

Psychotropic drugs and personality changes: A case of lithium.

The effect of psychopharmacological treatment on personality has been mostly studied with antidepressant drugs. Previously, we demonstrated an association between long-term lithium response and affective temperaments measured by the Temperament Scale of Memphis, Pisa, Paris and San Diego-Autoquestionnaire (TEMPS-A), and schizotypic traits, measured by the Oxford-Liverpool Inventory of Feelings and Experiences (O-LIFE). Therefore, we were interested whether long-term lithium treatment per se may influence personality traits measured by these scales. The study was performed on 40 patients with bipolar mood disorder (16 male, 24 female) with a mean age of 46 ± 10 years, either hospitalized or attending the outpatient clinic, Department of Adult Psychiatry, Poznan University of Medical Sciences. Among them, twenty patients (8 male, 12 female) have received lithium for 10-33 years, and twenty (8 male, 12 female) have never been exposed to lithium and have been given other mood-stabilizing drugs. Each patient, had the assessment made by the TEMPS-A and O-LIFE, during euthymic state. Patients on long-term lithium treatment were significantly older and had longer duration of bipolar illness compared with non-lithium patients. Lithium-treated patients obtained significantly lower scores of cyclothymic and irritable temperaments on the TEMPS-A, and of unusual experiences, cognitive disorganization and impulsive nonconformity on the O-LIFE. It is hypothesized that the differences in personality, revealed by the TEMPS-A and O-LIFE scales, are related to the long-term treatment with lithium. The decrease in cyclothymic temperament and in cognitive disorganization trait were previously shown to be associated with the therapeutic effect of lithium.

Neural correlates of creative thinking and schizotypy

Empirical studies indicate a link between creativity and schizotypal personality traits, where individuals who score highly on schizotypy measures also display greater levels of creative behaviour. However, the exact nature of this relationship is not yet clear, with only a few studies examining this association using neuroimaging methods. In the present study, the neural substrates of creative thinking were assessed with a drawing task paradigm in healthy individuals using fMRI. These regions were then statistically correlated with the participants’ level of schizotypy as measured by the Oxford–Liverpool Inventory of Feelings and Experiences (O-LIFE), which is a questionnaire consisting of four dimensions. Neural activations associated with the creativity task were observed in bilateral inferior temporal gyri, left insula, left parietal lobule, right angular gyrus, as well as regions in the prefrontal cortex. This widespread pattern of activation suggests that creative thinking utilises multiple neurocognitive networks, with creative production being the result of collaboration between these regions. Furthermore, the correlational analyses found the Unusual Experiences factor of the O-LIFE to be the most common dimension associated with these areas, followed by the Impulsive Nonconformity dimension. These correlations were negative, indicating that individuals who scored the highest in these factors displayed the least amount of activation when performing the creative task. This is in line with the idea that ‘less is more’ for creativity, where the deactivation of specific cortical areas may facilitate creativity. Thus, these findings contribute to the evidence of a common neural basis between creativity and schizotypy.

Hemispheric language asymmetry in first episode psychosis and schizotypy: the role of cannabis consumption and cognitive disorganization.

Cannabis use has been related to an elevated psychosis risk and attenuated cognitive functioning. Cannabis-related cognitive impairments are also observed in populations along the psychosis dimension. We here investigated whether a potential behavioral marker of the psychosis dimension (attenuated functional hemispheric asymmetry) is even further attenuated in individuals using cannabis (CU) vs those not using cannabis (nCU). We tested 29 patients with first-episode psychosis (FEP; 11 CU) and 90 healthy controls (38 CU) on lateralized lexical decisions assessing left-hemisphere language dominance. In patients, psychotic symptoms were assessed by Positive & Negative Symptom Scale (PANSS). In controls, self-reported schizotypy was assessed (The Oxford-Liverpool Inventory of Feelings and Experiences: O-LIFE). Results indicated that nCU FEP patients had a relative reduced hemispheric asymmetry, as did controls with increasing cognitive disorganization (CogDis) scores, in particular when belonging to the group of nCU controls. Positive, disorganized and negative PANSS scores in patients and negative and positive schizotypy in controls were unrelated to hemispheric asymmetry. These findings suggest that cannabis use potentially balances rather than exacerbates uncommon hemispheric laterality patterns. Moreover, in healthy populations, the potential stabilization of typical hemispheric asymmetry in CU might be most relevant to individuals with elevated CogDis. We discuss the potential beneficial and harmful effects of cannabis use along the psychosis dimension together with propositions for future studies that should account for the mediating role of additional substances (eg nicotine), cannabis composition (eg cannabidiol content), and individual differences (eg physical health, or absence of significant polysubstance use).

Schizotypy and impaired basic face recognition? Another non-confirmatory study.

Although schizotypy has been found to be reliably associated with a reduced recognition of facial affect, the few studies that have tested the association between basic face recognition abilities and schizotypy have found mixed results. This study formally tested the association in a large non-clinical sample with established neurological measures of face recognition. Two hundred and twenty-seven participants completed the Oxford-Liverpool Inventory of Feelings and Experiences schizotypy scale and completed the Famous Faces Test and the Cardiff Repeated Recognition Test for Faces. No association between any schizotypal dimension and performance on either of the facial recognition and learning tests was found. The null results can be accepted with a high degree of confidence. Further additional evidence is provided for a lack of association between schizotypy and basic face recognition deficits.

Neurophysiological correlates of configural face processing in schizotypy.

Background: Face processing impairment in schizophrenia appears to be underpinned by poor configural (as opposed to feature-based) processing; however, few studies have sought to characterize this impairment electrophysiologically. Given the sensitivity of event-related potentials to antipsychotic medications, and the potential for neurophysiological abnormalities to serve as vulnerability markers for schizophrenia, a handful of studies have investigated early visual P100 and face-selective N170 in “at risk” populations. However, this is the first known neurophysiological investigation of configural face processing in a non-clinical schizotypal sample.Methods: Using stimuli designed to engage configural processing in face perception (upright and inverted Mooney and photographic faces), P100 and N170 components were recorded in healthy individuals characterized by high (N = 14) and low (N = 14) schizotypal traits according to the Oxford–Liverpool Inventory of Feelings and Experiences.Results: High schizotypes showed significantly reduced N170 amplitudes to inverted photographic faces. Typical N170 latency and amplitude inversion effects (delayed and enhanced N170 to inverted relative to upright photographic faces, and enhanced amplitude to upright versus inverted Mooney faces), were demonstrated by low, but not high, schizotypes. No group differences were shown for P100 analyses.Conclusions: The findings suggest that neurophysiological deficits in processing facial configurations (N170) are apparent in schizotypy, while the early sensory processing (P100) of faces appears intact. This work adds to the mounting evidence for analogous neural processing anomalies at the healthy end of the psychosis continuum.

Psychotic traits in comedians

The popular belief that creativity is associated with madness has increasingly become the focus of research for many psychologists and psychiatrists. However, despite being prime examples of creative thinking, comedy and humour have been largely neglected. To test the hypothesis that comedians would resemble other creative individuals in showing a higher level of psychotic characteristics related to both schizophrenia and manic depression. A group of comedians (n = 500+) and a control sample of actors (n = 350+) completed an online questionnaire containing the short version of the Oxford-Liverpool Inventory of Feelings and Experiences (O-LIFE), with scales measuring four dimensions of psychotic traits. Scores were compared with general population norms. Comedians scored significantly above O-LIFE norms on all four scales. Actors also differed from the norms but on only three of the scales. Most striking was the comedians' high score on both introverted anhedonia and extraverted impulsiveness. This unusual personality structure may help to explain the facility for comedic performance.

Molecular biology of the fully-dimensional schizotypy-model

Schizotypy constitutes a useful model for the study of schizophreniform traits in healthy individuals, as it circumnavigates many confounders found in schizophrenia-patients. To examine molecular-biological indicators of the fully-dimensional schizotypy-model, the German version of the Oxford-Liverpool Inventory of Feelings and Experiences (O-LIFE) was examined regarding its associations with select relevant genetic polymorphisms. We present a number of influences of dopaminergic as well as non-dopaminergic genetic variants on sub-facets of schizotypy, whereof all can be interpreted in line with the current dopamine-hypothesis of psychosis in schizophrenia. Additionally, we examined correlations between schizotypy-dimensions and expression-levels of potentially relevant genes in the peripheral blood of healthy males. Preliminary analyses show significant correlations between the O-LIFE subscales and the expression of genes involved, i.a., in dopamine-regulation. Our findings indicate that schizotypy and schizophrenia share commonalities on the molecular-biological level. We therefore suggest the fully-dimensional schizotypy-model be further evaluated regarding its biological foundations.

Further evidence for high rates of schizophrenia in 22q11.2 deletion syndrome

22q11.2 deletion syndrome (22q11.2DS) is associated with high rates of psychotic disorder, particularly schizophrenia. The deletion is considered to be a biological model for understanding this debilitating psychiatric disorder. It is unclear whether the psychotic manifestations in 22q11.2DS are similar to those in schizophrenia patients without the deletion. Catechol-O-methyltransferase (COMT), a positional candidate gene for schizophrenia, resides within the 22q11.2 region. It remains unknown whether hemizygosity for this gene is associated with risk of psychotic disorder. This study includes 83 adults with 22q11.2DS, 90 non-deleted individuals with schizophrenia, and 316 normal controls. Psychopathology was assessed using the Schedules for Clinical Assessment in Neuropsychiatry, the Schedules for the Assessment of Positive and Negative Symptoms and the Global Assessment Scale. Schizotypy was assessed with the Kings Schizotypy Questionnaire and Oxford Liverpool Inventory of Feelings and Emotions. IQ estimates were also obtained. Adults with 22q11.2DS were genotyped for a number of COMT polymorphisms as well as the Ashkenazi risk haplotype.This study confirms high rates of psychotic disorder (29%) in individuals with 22q11.2DS of which the majority had schizophrenia (22%). There does not appear to be a differential expression of schizophrenic symptom clusters in 22q11.2DS in relation to sporadic schizophrenia, though schizophrenia in 22q11.2DS seems to be less severe in terms of global assessment scores. Psychosis proneness seems to be of genetic origin in 22q11.2DS as individuals with 22q11.2DS without schizophrenia had higher schizotypy scores than normal controls. Finally, COMT was not associated with schizophrenia status or schizotypy.

The Oxford-Liverpool Inventory of Feelings and Experiences (O-LIFE) schizotypy scale in psychiatry

The aim of this paper is to describe a schizotypy scale, the Oxford-Liverpool Inventory of Feelings and Experiences (O-LIFE), and its use in psychiatry. Schizotypy is a biologically determined personality phenomenon. Schizotypal disorder, as a diagnostic category in contemporary psychiatric classifications, has been included in schizophrenia spectrum disorders. This may reflect similarities in neurobiological and neuropsychological features between persons with schizotypy and patients with schizophrenia. However, schizotypal traits are also more marked in bipolar disorder (BD) compared with those in healthy subjects. The O-LIFE was created by Claridge and his co-workers and consists of four dimensions: unusual experiences, cognitive disorganisation, introvertive anhedonia and impulsive nonconformity. Studies using O-LIFE in psychiatry, demonstrated a number of associations between the dimensions of the O-LIFE and the clinical features of schizophrenia, in mood disorders and in healthy persons. In patients with BD treated with lithium carbonate, worse effects of lithium were observed in subjects with high scores on the O-LIFE dimensions (particularly cognitive disorganisation). Recently, some molecular-genetic associations have also been shown between O-LIFE dimensions and polymorphisms of the dopaminergic system and circadian rhythm genes.

An investigation of a novel transdiagnostic model of delusions in a group with positive schizotypal symptoms

IntroductionAlthough several theories of delusions have been put forward, most do not offer a comprehensive diagnosis-independent explanation of delusion aetiology. This study used a non-clinical sample to provide empirical support for a novel transdiagnostic model of delusions that implicates aberrant semantic memory and emotion perception processes as key factors in delusion formation and maintenance. It was hypothesised that among a non-clinical sample, people high in schizotypy would demonstrate differences in semantic memory and emotion perception, relative to people low in schizotypy.MethodsUsing the Cognitive Disorganisation subscale of the Oxford-Liverpool Inventory of Feelings and Experiences, 41 healthy participants were separated into high and low schizotypy groups and completed facial emotion perception and semantic priming tasks.ResultsAs expected, participants in the high schizotypy group demonstrated different performance on the semantic priming task and reduced facial affect accuracy for the emotion anger, and reaction time differences to fearful faces.ConclusionThese findings suggest that such processes may be involved in the development of the sorts of unusual beliefs which underlie delusions. Investigation of how emotion perception and semantic memory may interrelate in the aetiology of delusions would be of value in furthering our understanding of their role in delusion formation.

Latent profile analysis of healthy schizotypy within the extended psychosis phenotype

Converging evidence suggests that psychosis exists on a continuum, and that even mentally “healthy” individuals may experience subclinical psychotic experiences. However, little research has examined the subjective and psychological well-being of individuals in the putatively healthy end of the continuum. This study explored the latent profile structure of schizotypy in a non-clinical sample and compared subjective and psychological well-being across schizotypy profiles. Latent profile analysis was conducted on participants' responses (N=420) to the Oxford-Liverpool Inventory of Feelings and Experiences. Six latent profiles emerged: Low Schizotypy, Average, High Schizotypy, High Unusual Experiences (UE), High Introvertive Anhedonia, and High Introvertive Anhedonia/Cognitive Disorganization. Individuals in the profile characterized by high UE without negative, disorganized or impulsive features tended to endorse similar levels of well-being as the Average and Low Schizotypy profiles. With some exceptions, all three profiles also demonstrated significantly greater subjective and psychological well-being when compared to negative/disorganized schizotypy profiles. The UE profile most closely aligns with previous conceptualizations of “healthy schizotypy.” Future research should investigate how individuals in this profile make sense of unusual or ambiguous experiences that may lead to distress in clinical populations.

Investigating word associations in a schizotypy sample: Contrasting implicit and explicit processing

IntroductionSchizotypy is a useful schizophrenia analogue that controls for confounding factors such as medication and general intellectual decline. In the current study this analogue approach was used to examine implicit/explicit and direct/indirect semantic memory function. This is the first study to examine both implicit and explicit semantic access in the same schizotypy sample.MethodsParticipants completed four semantic tasks: (1) implicit indirect priming, (2) implicit direct priming, (3) explicit object (indirect) task, and (4) explicit association (direct) task. The schizophrenia literature suggests that semantic impairments are associated with thought disorder. As such, participants were divided into low (n=18) and high (n=18) schizotypy groups based on their responses to a thought disorder subscale of the Oxford Liverpool Inventory of Feelings and Experiences (O-Life) scale.ResultsIn terms of implicit performance, the high schizotypy group demonstrated increased direct priming but nonsignificant indirect priming. The low schizotypy group demonstrated no significant difference in direct and indirect priming. Performance on the explicit tasks was equivalent between the two groups for direct stimuli. On the indirect explicit task, high schizotypy was associated with an increase in errors.ConclusionsIncreased direct priming in high schizotypy is equivalent to that seen in schizophrenia, which has been interpreted as increased spreading of activation. Abnormal performance using the indirect stimuli was found across implicit and explicit versions. The relevance of these findings to schizophrenia are discussed.

An investigation of schizotypy in injecting amphetamine users

A fully dimensional view of psychiatric disorder conceptualises schizotypy as both a continuous personality trait and an underlying vulnerability to the development of psychotic illness. Such a model would predict that the structure of schizotypal traits would closely parallel the structure of schizophrenia or psychosis. This was investigated in injecting amphetamine users (N=322), a clinical population who have high rates of acute psychotic episodes and subclinical schizotypal experiences. Schizotypy was assessed using the Oxford-Liverpool Inventory of Feelings and Experiences (O-LIFE), and psychotic symptoms were assessed using the Brief Psychiatric Rating Scale (BPRS). Using confirmatory factor analysis, O-LIFE subscale scores were mapped onto latent variables with their more clinical counterparts from the BPRS. A four-factor model comprising positive schizotypy, disorganisation, negative schizotypy, and disinhibition provided the best model fit, consistent with prior research into the structure of schizotypy. The model provided a good fit to the data, lending support to the theory that schizotypy and psychotic symptoms map onto common underlying dimensions.

P.4.010 Association of personality features with lithium prophylactic response

Schizotypy is a multidimensional construct indexing psychometric risk for schizophrenia. This study investigated the factor structure and clinical associations of the Oxford-Liverpool Inventory of Feelings and Experiences (O-LIFE) short scales, assessed at follow-up in an originally help-seeking sample identified as ultra-high risk for psychosis.Participants were 228 help-seeking individuals identified as ultra-high risk for psychosis between 2 and 14 years previously (mean, 7.09; SD, 3.17; median, 6.41). The 43-item O-LIFE short scales (Unusual Experiences, Introvertive Anhedonia, Cognitive Disorganization, Impulsive Nonconformity) and indices of depression, anxiety, positive and negative psychotic symptoms, functioning, and quality of life were administered at follow-up. Structural equation modeling was used.Impulsive Nonconformity was shown to be an unstable factor and was excluded. A 3-factor model of Unusual Experiences, Cognitive Disorganization, and Introvertive Anhedonia was found to be the best description of the data, compared with a 1-factor model. Unusual Experiences factor was associated with positive psychotic symptoms; Cognitive Disorganization was associated with depression and anxiety; and Introvertive Anhedonia was associated with positive and negative psychotic symptoms, quality of life, and functioning.The Impulsive Nonconformity factor of the O-LIFE short scales should be interpreted with caution. A well-fitting 3-factor model provides support for a dimensional structure in schizotypy that is similar to that of schizophrenia. Separate dimensions were differentially associated with psychopathology, functioning, and quality of life. The interpersonal dimension of schizotypy was the only dimension associated with poorer functioning and quality of life and may be a sensitive indicator of need for care.

Inferring about individual drug and schizotypy effects on cognitive functioning in polydrug using mephedrone users before and after clubbing

Mephedrone has been recently made illegal in Europe, but little empirical evidence is available on its impact on human cognitive functions. We investigated acute and chronic effects of mephedrone consumption on drug-sensitive cognitive measures, while also accounting for the influence of associated additional drug use and personality features. Twenty-six volunteers from the general population performed tasks measuring verbal learning, verbal fluency and cognitive flexibility before and after a potential drug-taking situation (pre-clubbing and post-clubbing at dance clubs, respectively). Participants also provided information on chronic and recent drug use, schizotypal (Oxford-Liverpool Inventory of Feelings and Experiences) and depressive symptoms (Beck Depression Inventory), sleep pattern and premorbid IQ. We found that (i) mephedrone users performed worse than non-users pre-clubbing and deteriorated from the pre-clubbing to the post-clubbing assessment; (ii) pre-clubbing cannabis and amphetamine (not mephedrone) use predicted relative cognitive attenuations; (iii) post-clubbing, depression scores predicted relative cognitive attenuations; and (iv) schizotypy was largely unrelated to cognitive functioning, apart from a negative relationship between cognitive disorganisation and verbal fluency. Results suggest that polydrug use and depressive symptoms in the general population negatively affect cognition. For schizotypy, only elevated cognitive disorganisation showed potential links to a pathological cognitive profile previously reported along the psychosis dimension.

Impact of Adverse Life Events on Individuals With Low and High Schizotypy in a Nonpatient Sample

The aims of this study were to gain a better understanding of adverse life events connected with the development of schizotypal personality traits and, also, to examine whether subclinical schizotypy has a relationship with vulnerability to traumatic intrusions and avoidance. In a cross-sectional design, 198 undergraduate students completed the Oxford-Liverpool Inventory of Feelings and Experiences (O-LIFE), the Impact of Event Scale (IES), and Paykel's Life Events Scale, together with other relevant scales. The number of adverse life events was significantly related to overall schizotypy measured by O-LIFE scores and positive schizotypy measured by the Unusual Experiences (UnEx) subscale. The subjective severity of life events was significantly related to Cognitive Disorganization (CogDis). Measures of positive schizotypy (UnEx and CogDis) were significantly related to the scores on the IES and on the intrusion and avoidance subscales, too. Adverse life events are associated with schizotypal personality traits, which contribute to a tendency for traumatic intrusions, even in a nonpatient sample.
