To determine the clinical and demographic correlates of persistent, remitting, and new-onset impulse control behaviors (ICBs) before and after subthalamic deep brain stimulation (STN-DBS) in Parkinson's disease (PD). We compared the pre- and post-surgical prevalence of ICBs, classified as impulse control disorders (ICD), dopamine dysregulation syndrome (DDS), and punding in 150 consecutive PD STN-DBS-treated patients and determined the association with motor, cognitive, neuropsychological, and neuropsychiatric endpoints...

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)...

Some personal drives correspond to extraordinary social roles. Given that behavioral strategies associated with such drives may conflict with those associated with ordinary roles, they could cause behavioral disorganization. To test whether they do so independent of the factors responsible for full-blown schizotypy and schizophrenia, these drives were assessed in the general population. Two hundred and nine healthy volunteers were individually presented with hundreds of names of social roles in experimental psychology conditions...

Few typological studies address schizotypy in young adults. Schizotypal traits were assessed on 466 college students using the Schizotypal Personality Questionnaire-Brief (SPQ-B). Other measures evaluated personality traits previously associated with schizotypy (borderline, obsessionnal, and autistic traits), psychopathological symptoms (suicidal ideations, depressive and obsessive-compulsive symptoms) and psychosocial functioning. A factor analysis was first performed on SPQ-B results, leading to four factors: negative schizotypy, positive schizotypy, social anxiety, and reference ideas...

Minor physical anomalies (MPAs) are subtle signs of fetal developmental abnormalities that have been considered to be among the most replicated risk markers for schizophrenia-spectrum disorders. However, quantitative approaches are needed to measure craniofacial MPAs. The present study adopted an imaging-based quantitative approach to examine craniofacial MPAs across the spectrum of schizophrenia and affective disorders, to address their sensitivity and specificity. We sampled 31 patients with schizophrenia, 30 of their unaffected relatives, and 30 individuals with schizotypal personality traits, as well as 37 non-schizotypal controls...

The presence of obsessive-compulsive symptoms (OCS) and obsessive-compulsive disorders (OCD) in schizophrenia is frequent, and a new clinical entity has been proposed for those who show the dual diagnosis: the schizo-obsessive disorder. This review scrutinizes the literature across the main academic databases, and provides an update on different aspects of schizo-obsessive spectrum disorders, which include schizophrenia, schizotypal personality disorder (SPD) with OCD, OCD with poor insight, schizophrenia with OCS, and schizophrenia with OCD (schizo-obsessive disorder)...

Social anhedonia, the reduced capacity for social and interpersonal pleasure, often accompanies several forms of psychopathology. The goal of the present study was to validate the Chinese translation of the Anticipatory and Consummatory Interpersonal Pleasure Scale (ACIPS), a promising new tool for the assessment of individual differences in social pleasure. The Chinese versions of the ACIPS, the Temporal Experience of Pleasure Scale (TEPS), and the Schizotypal Personality Questionnaire (SPQ) were administered to 389 nonclinical adults...

INTRODUCTION: The main objective of the study was to explore the factorial structure of the French version of the Schizotypal Personality Questionnaire-Brief (SPQ-B) in a Likert format, in a representative sample of the general population. In addition, differences in the dimensional scores of schizotypy according to gender and age were analyzed. As the study in the general population of schizotypal traits and its determinants has been recently proposed as a way toward the understanding of aetiology and pathophysiology of schizophrenia, consistent self-report tools are crucial to measure psychometric schizotypy...

AIM: To determine characteristics of cognitive insight and its relationship with the severity and dynamics of symptoms in patients with ultra-high risk for schizophrenia during treatment. MATERIAL AND METHODS: The study included 76 young patients with subpsychotic symptoms corresponding to criteria of ultra-high risk for psychosis and 55 healthy subjects. Patients were examined using psychopathological analysis and a battery of psychological tests. RESULTS AND CONCLUSION: Cognitive insight, although not linked to objective indicators of ultra-high risk for schizophrenia, predicts a decline in both total score of SOPS, and in the Positive symptoms subscale during the treatment of patients with personality disorders...

BACKGROUND: A key finding underlying the continuum of psychosis concept is the presence of psychotic-like experiences (PLEs) in healthy subjects. However, it remains uncertain to what extent these experiences are related to the genetic risk for schizophrenia and how far they actually resemble attenuated forms of psychotic symptoms. METHODS: Forty-nine adults with no history of mental illness in first-degree relatives and 59 siblings of patients with schizophrenia were rated on the psychosis section of the Computerized Diagnostic Interview Schedule IV (C DIS-IV) and the Rust Inventory of Schizotypal Cognitions (RISC)...

BACKGROUND: Increased schizotypal traits are observed in a percentage of the general population and in the schizophrenia-spectrum and have been associated with impairments in working memory. In this study we examined the effects of four schizotypal dimensions [Negative (NegS), Paranoid (ParS), Cognitive-Perceptual (CPS), Disorganized (DiS)] on executive working memory (EWM), as mediated by set-shifting, planning and control inhibition. We also examined whether these associations are moderated by family-history of psychosis...

AIM: A clinical high risk (CHR) for psychosis is regarded as the state of being at risk of developing psychosis. However, the rate of transition to psychosis among CHR subjects has been declining over time. We aimed to investigate the effects of the possible causes of the declining transition rate. METHODS: A total of 129 CHR subjects were divided into two groups according to the date of enrollment: the 2005-2009 group and the 2009-2013 group. Baseline demographic and clinical characteristics, including medication prescription, were compared...

BACKGROUND: Cultural and personality factors might contribute to the clinical differences of psychiatric patients all over the world including China. One cultural oriented Chinese Adjective Descriptors of Personality (CADP) designed to measure normal personality traits, might be specifically associated with different personality disorder functioning styles. METHODS: We therefore have invited 201 healthy volunteers and 67 personality disorder patients to undergo CADP, the Parker Personality Measure (PERM), and the Plutchik-van Praag Depression Inventory (PVP) tests...

AIM: Schizoid (ScPD) and Schizotypal (SPD) personality disorders are rare and severe disorders. They are associated with high liability to schizophrenia and present an attenuated form of its negative symptoms, which are considered a putative endophenotype for schizophrenia. The trans-diagnostic study of negative symptoms in non-psychotic populations such as ScPD/SPD might provide useful markers of a negative-symptom domain; however, little is known about their neurobiological substrates...

Mental time travel refers to the ability to recall past events and to imagine possible future events. Schizophrenia (SCZ) patients have problems in remembering specific personal experiences in the past and imagining what will happen in the future. This study aimed to examine episodic past and future thinking in SCZ spectrum disorders including SCZ patients and individuals with schizotypal personality disorder (SPD) proneness who are at risk for developing SCZ. Thirty-two SCZ patients, 30 SPD proneness individuals, and 33 healthy controls participated in the study...

Spontaneous dyskinesia is associated with non-affective psychosis. Few studies investigated dyskinesia in individuals with subclinical psychotic experiences. We examined dyskinesia using instrumental measurements of force variability in 34 individuals with frequent auditory verbal hallucinations but without a clinical psychotic disorder and 31 matched healthy controls. Schizotypy was assessed using the Schizotypal Personality Questionnaire. We found a positive correlation between dyskinesia and schizotypy in the total group...
