Schizoid personality disorder

Martin Sellbom, Alexander Smith
The Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF; Ben-Porath & Tellegen, 2008 / 2011 ) is frequently used in clinical practice. However, there has been a dearth of literature on how well this instrument can assess symptoms associated with personality disorders (PDs). This investigation examined a range of hypothesized MMPI-2-RF scales in predicting PD symptoms. We evaluated these associations in a sample of 397 university students who had been administered the MMPI-2-RF and the Structured Clinical Interview for DSM-IV Axis II Disorders-Personality Questionnaire (First, Gibbon, Spitzer, Williams, & Benjamin, 1997 )...

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...

Although evidence with respect to its prevalence is mixed, it is clear that fathers perpetrate a serious proportion of filicide. There also seems to be a consensus that paternal filicide has attracted less research attention than its maternal counterpart and is therefore less well understood. National registries are a very rich source of data, but they generally provide limited information about the perpetrator as psychiatric, psychological and behavioral data are often lacking. This paper presents a fully documented case of a paternal filicide...

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...

BACKGROUND: There is consistent evidence about the relationship between smoking and mental health. This study compares the relationship between tobacco use and personality disorders (PDs) in Spanish adults from general and clinical population, taking into account nicotine dependence (ND), and the presence of any mental disorder. METHOD: The sample was made up of 1,079 smokers (519 from general population, 560 from clinical population). PDs were assessed by means of the International Personality Disorder Examination Questionnaire, Module DSM-IV...

Personality disorders (PDs) are commonly found in adults with attention-deficit/hyperactivity disorder (ADHD) and are associated with increased ADHD symptoms and psychosocial impairment. To assess the impact of PDs or personality traits on retention rates in ADHD trials and whether treating ADHD affects the expression of PD, data were analyzed from 2 methylphenidate trials. Assessment of PDs and personality traits included using the Wisconsin Personality Disorders Inventory IV and the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition Personality Disorders...

Though researchers have attended to disorganized attachment in infants and children, they have infrequently focused on the character of disorganized attachment in adults. In this study, we aimed to identify clusters of participants based on attachment levels and styles, seeking to better delineate severity and stylistic differences in disorganized attachment than has been previously articulated. We used a new assessment approach focused on a hierarchy of attachment organization, including secure, insecure (dismissive and preoccupied), rigid-controlling (hostile control and compulsive caregiving), and disorganized (contradictory, impoverished, and unresolved) levels of attachment...

BACKGROUND: Cluster headache (CH) has been associated with certain personality traits and lifestyle features, but there are few studies assessing personality profiles in CH. We aimed to analyze personality traits in patients with CH, and to compare them with those found in migraine. METHODS: We included all consecutive patients with CH attending 5 outpatient offices between January and December 2013. Personality traits were evaluated using the Salamanca screening test, a validated inventory assessing 11 personality traits grouped in 3 clusters...

INTRODUCTION: Aripiprazole, an atypical or second-generation antipsychotic, is usually well tolerated. It is an approved treatment for schizophrenia and mania in bipolar disorder type 1. Unlike the other antipsychotics, it has high affinity agonist properties for dopamine D2 and D3 receptors. It has also 5-HT1A partial agonist and 5-HT2A antagonist properties. Aripiprazole is a first or second line treatment frequently used because it has reduced side effects such as weight gain, sleepiness, dyslipidemia, insulin resistance, hyperprolactinemia and extrapyramidal symptoms...

BACKGROUND: Internet addiction or problematic Internet use is a recent and increasingly recognized disorder which has been consistently associated with many psychiatric disorders, adding to the documented negative consequences of problematic Internet use. However, very few studies have examined the relationship between problematic Internet use and personality traits and none in a French sample. Moreover, those which have evaluated this relationship have mainly been conducted on small samples...

OBJECTIVE: This study investigated the relationship between regional cortical gray matter thinning and symptoms of schizophrenia spectrum personality disorders (PDs) in siblings of patients with childhood-onset schizophrenia (COS). METHOD: A total of 66 siblings of patients with COS were assessed for symptoms of schizophrenia spectrum PDs (avoidant, paranoid, schizoid, schizotypal). Structural magnetic resonance images were obtained at approximately 2-year intervals from the siblings and from 62 healthy volunteers matched for age, sex, ethnicity, and handedness...

Proposed for the Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5) was a five-domain, 25-dimensional trait model that would have constituted a significant part of the diagnostic criteria for each personality disorder. A primary concern with respect to the proposal was that clinicians might find such an approach to be unacceptable. This study provides results from three independent data collections that compared clinicians' clinical utility ratings for each iteration of the DSM-5 dimensional trait assignments, along with an alternative list of traits derived from the Five Factor Form (FFF)...

UNLABELLED: Gender-based violence (GBV) is prevalent and associated with deleterious outcomes including posttraumatic stress disorder, depression, and substance use disorders. Despite substantial comorbidity between these conditions and personality disorders (PDs), few, if any, studies have examined associations between lifetime exposure to GBV and risk for a range of PDs in nationally representative U.S. SAMPLES: The current study addressed this gap in the literature by examining adjusted odds ratios (aORs) and population attributable fractions (PAFs) of 10 PDs by lifetime GBV exposure...

This field trial examines the discriminant validity of five trait domains of the originally proposed research algorithm for diagnosing International Classification of Diseases (ICD)-11 personality disorders. This trial was carried out in South Korea where a total of 124 patients with personality disorder participated in the study. Participants were assessed using originally proposed monothetic trait domains of asocial-schizoid, antisocial-dissocial, anxious-dependent, emotionally unstable and anankastic-obsessional groups of the research algorithm in ICD-11...

BACKGROUND: Anorexia Nervosa (AN) is a psychiatric illness associated with a number of personality disturbances. However, whether these personality characteristics are related to eating disorder symptomatology or emotion regulation is unclear. The aim of this study was to investigate these relationships. RESULTS: Twenty-four individuals with AN and 25 age- and premorbid intelligence-matched controls completed the Personality Diagnostic Questionnaire, and scores were correlated with measures of emotionality and negative mood states, and eating disorder symptomatology...

BACKGROUND: Nonfatal suicidal behaviours (NSB), including suicide ideation, suicide plan and suicide attempt, constitute a serious problem for public healthcare services. Suicide gesture (SG) which refers to self-injurious behaviour with no intent to die, differs from NSB in a variety of important ways. The aim of this study was to investigate demographic and clinical characteristics of NSB and SG to examine whether self-injurers with intent to die differ significantly from self injurers without such intent...

Personality disorder symptomatology (PD-Sx) can result in personal distress and impaired interpersonal functioning, even in the absence of a clinical diagnosis, and is frequently comorbid with psychiatric disorders such as substance use, mood, and anxiety disorders; however, they often remain untreated, and are not taken into account in clinical studies. To investigate brain morphological correlates of PD-Sx, we measured subcortical volume and shape, and cortical thickness/surface area, based on structural magnetic resonance images...
