Schizophrenia has generally been viewed as having a unique preschizophrenia personality or destructive to the personality post-onset. This view is reflected in the scarcity of studies of personality in schizophrenia with the exception of schizotypal personality considered by many as an endophenotype of schizophrenia. What is missing is the study of personality as independent of schizophrenia and as a potential source of schizophrenia heterogeneity. In this study we examine sex versus gender as an initial effort to introduce personality as a normal variant that influences how schizophrenia is expressed...

This study evaluated how change in posttraumatic stress disorder (PTSD) symptoms was associated with residualized change in comorbid personality disorder (PD) features and vice versa over the course of 5-10 years. The sample was comprised of 79 female rape survivors who met criteria for PTSD and who were a part of a larger study examining the effects of trauma-focused therapy. PTSD was assessed with the fourth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) version of the Clinician-Administered PTSD Scale [CAPS-IV (1)] and PD features were assessed with the DSM-IV dimensional PD scales on the Schedule for Non-adaptive and Adaptive Personality [SNAP (2)]...

BACKGROUND: Schizotypal personality disorder (SPD) is linked to schizophrenia in terms of shared genetics, biological markers and phenomenological characteristics. In the current study, we aimed to determine whether the previously reported altered functional connectivity (FC) with precuneus in patients with schizophrenia could be extended to individuals with SPD. METHODS: Twenty subjects with SPD and 19 healthy controls were recruited from 4461 freshmen at a university in Shanghai and received a resting-state scan of MRI...

Prospective evaluation of youths with early psychotic-like experiences can enrich our knowledge of clinical, biobehavioral and environmental risk and protective factors associated with the development of psychotic disorders. We aimed to investigate the predictors of persistence or worsening of psychosis spectrum features among US youth through the first large systematic study to evaluate subclinical symptoms in the community. Based on Time 1 screen of 9,498 youth (age 8-21) from the Philadelphia Neurodevelopmental Cohort, a subsample of participants was enrolled based on the presence (N=249) or absence (N=254) of baseline psychosis spectrum symptoms, prior participation in neuroimaging, and current neuroimaging eligibility...

Identifying endophenotypes of schizophrenia is of critical importance and has profound implications on clinical practice. Here we propose an innovative approach to clarify the mechanims through which temperament and character deviance relates to risk for schizophrenia and predict long-term treatment outcomes. We recruited 61 antipsychotic naïve subjects with chronic schizophrenia, 99 unaffected relatives, and 68 healthy controls from rural communities in the Central Andes. Diagnosis was ascertained with the Schedules of Clinical Assessment in Neuropsychiatry; parkinsonian motor impairment was measured with the Unified Parkinson's Disease Rating Scale; mesencephalic parenchyma was evaluated with transcranial ultrasound; and personality traits were assessed using the Temperament and Character Inventory...

Impaired social functioning is a hallmark of major psychiatric disorders. The purpose of this study was to detect a disorder-specific factor of social dysfunction among patients with major psychiatric disorders (PSY), including schizophrenia (SCZ), bipolar disorder (BIP) and major depressive disorder (MDD). Social functioning was assessed in patients with SCZ (n=80), BIP (n=27) or MDD (n=29) and healthy controls (HC, n=68) using the Social Functioning Scale (SFS). Compared to HC, the SCZ, BIP and MDD patient groups showed lower total SFS scores...

Unusual interaction behaviors and perceptual aberrations, like those occurring in schizotypy and schizophrenia, may in part originate from impaired remapping of environmental stimuli in the body space. Such remapping is contributed by the integration of tactile and proprioceptive information about current body posture with other exteroceptive spatial information. Surprisingly, no study has investigated whether alterations in such remapping occur in psychosis-prone individuals. Four hundred eleven students were screened with respect to schizotypal traits using the Schizotypal Personality Questionnaire...

We investigated stability and change in personality disorder (PD) symptoms and whether depression severity, comorbid clinical psychiatric disorders, and social support predict changes in personality pathology among adolescent outpatients. The 1-year outcome of PD symptoms among consecutive adolescent psychiatric outpatients with depressive disorders (N = 189) was investigated with symptom count of depression, comorbid psychiatric disorders, and perceived social support as predictors. An overall decrease in PD symptoms in most PD categories was observed...

Objective: It is unclear why some individuals reporting psychotic experiences have balanced lives while others go on to develop mental health problems. The objective of this study was to test if the personality traits of harm avoidance, self-directedness, and self-transcendence can be used as criteria to differentiate healthy from unhealthy schizotypal individuals. Methods: We interviewed 115 participants who reported a high frequency of psychotic experiences. The instruments used were the Temperament and Character Inventory (140), Structured Clinical Interview for DSM-IV, and the Oxford-Liverpool Inventory of Feelings and Experiences...

Increased cytokines and kynurenic acid (KYNA) levels in cerebrospinal fluid (CSF) have been reported in patients with schizophrenia and bipolar disorder. The aim of the present study was to investigate cytokines and kynurenines in the CSF of twin pairs discordant for schizophrenia or bipolar disorder and to study these CSF markers in relation to psychotic symptoms and personality traits. CSF levels of tryptophan (TRP), KYNA, quinolinic acid (QUIN), interleukin (IL)-6, IL-8 and tumor necrosis factor-alpha (TNF-α) were analyzed in 23 twins with schizophrenia or bipolar disorder, and in their not affected co-twins...

Associations between schizotypal traits and genes coding for inflammation markers (Creactive protein and TNF-α) were studied in 222 healthy men who completed the Schizotypal Personality Questionnaire (SPQ-74). CRP -717A>G and TNFα -308 G>A polymorphisms were genotyped. Carriers of low-active allele G of the CRP gene differed from subjects with genotype AA by a trend toward more manifest schizotypal traits in general and scores on the Interpersonal factor, which corresponds to negative syndrome in schizophrenia, and Constricted affect and Odd behavior scales...

PURPOSE OF REVIEW: This review summarizes recent executive functions research to better delineate the nosology of personality disorders. RECENT FINDINGS: This review indicates that there are consistent impairments in executive functioning in people with personality disorders as compared with matched controls. Only five disorders were considered: borderline, obsessive-compulsive, antisocial, narcissistic, and schizotypal. Significant deficits are observed in decision-making, working memory, inhibition, and flexibility...

Striatal abnormalities play a crucial role in the pathophysiology of schizophrenia. Growing evidence suggests an association between aberrant striatal activity during reward anticipation and symptom dimensions in schizophrenia. However, it is not clear whether this holds across the psychosis continuum. The aim of the present study was to investigate alterations of ventral striatal activation during reward anticipation and its relationship to symptom expression in persons with schizotypal personality traits (SPT) and first-episode psychosis...

Individuals with a personality disorder (PD) tend to experience more negative life events (NLEs) than positive life events (PLEs). In community samples, the Five Factor Model of personality (FFM) predicts both positive and negative life events. The present research examined whether FFM normal personality traits were associated with positive and negative life events among individuals with 1 of 4 PDs: avoidant, borderline, schizotypal, and obsessive-compulsive, and tested whether associations between the FFM of personality and PLEs and NLEs were similar across the 4 PD groups and a control group...

PURPOSE OF REVIEW: This article aims to examine the relationships between obsessive-compulsive disorder (OCD) and personality disturbance, with a particular focus on the diagnostic, aetiological and treatment implications of these relationships. RECENT FINDINGS: Personality disorders are common in OCD. They interact in various ways and in accordance with a number of the proposed models. The relationship between OCD and obsessive-compulsive personality disorder is the most important, but it can be conceptualised in different ways and may vary from one person to another...

The main goal of the present study was to test the measurement equivalence of the Schizotypal Personality Questionnaire - Brief Revised (SPQ-BR) scores in a large sample of Spanish and American non-clinical young adults. The sample was made up of 5,625 young adults (M = 19.65 years; SD = 2.53; 38.5% males). Study of the internal structure, using confirmatory factor analysis (CFA), revealed that SPQ-BR items were grouped in a theoretical internal structure of nine first-order factors. Moreover, three or four second-order factor and bifactor models showed adequate goodness-of-fit indices...

The purpose of the present study was to compare the cognitive and perceptual aberration scales from the Five-Factor Schizotypal Inventory (FFSI; Edmundson, Lynam, Miller, Gore, & Widiger, 2011) and the Personality Inventory for DSM-5 (Krueger, Derringer, Markon, Watson, & Skodol, 2012), as well as to address more generally the validity of the FFSI as a measure of both schizotypal personality traits and the FFM. Two independent samples were obtained, including 259 college students (55 of whom were preselected with elevated scores on a measure of schizotypal personality disorder [STPD]) and 346 adult MTurk participants (43% of whom had been or were currently in mental health treatment)...
