Schizoid personality disorder

Schizophrenia-spectrum psychopathology appears best understood as being expressed across a continuum of clinical and subclinical symptoms and impairment referred to as schizotypy. This brief report describes a comprehensive replication study examining the associations of positive, negative, and disorganized schizotypy with interview ratings of impairment, psychopathology, and personality pathology in a sample of 161 young adults. Consistent with past studies, positive, negative, and disorganized schizotypy had distinct and hypothesized associations with symptoms and impairment...

METHODS: In this descriptive-correlational study conducted in 2021, 160 patients with type 2 diabetes referred to the diabetes clinic of Imam Khomeini Educational and Medical Center in Ardabil were selected by convenience sampling method...

OBJECTIVE: The neurophysiological objectification of intranosological differentiation of main clusters (schizoid/paranoid and hysterical/emotionally unstable) within the typology of personality disorders (PD), as well as the differentiation of schizoid/paranoid PD and schizophrenia. MATERIAL AND METHODS: Two groups of patients with PD participated in the study: PD1 - with schizoid/paranoid pattern ( n =16), and PD2 - with hysterical/emotionally unstable pattern ( n =18)...

OBJECTIVES: The International Classification of Diseases , 11th edition includes a new personality disorder diagnosis, in light of growing concerns of the categorical personality disorder diagnoses. The purpose of the current study was to examine the reliability and validity of the severity dimension of the new International Classification of Diseases , 11th edition diagnosis, through multi-method assessment. METHOD: In a community mental health sample ( n = 311), we examined the interrater reliability of the severity diagnosis and evaluated the diagnosis against self-report measures of dimensional personality pathology and psychopathology constructs and traditional categorical and informant-report measures...

Introduction: Sex differences in the frequency and severity of personality disorders (PDs) have been widely reported in Western countries. However, limited literature suggests a similar sex distribution in the Chinese clinical population. This study investigated sex differences in self-reported and interviewed patients with PDs in a clinical population in China. Materials and methods: The participants were 1,389 consecutive outpatients with a mean age of 30.5 years, including 634 (45...

Vaccines are crucial to ending the COVID-19 pandemic. An mRNA-based COVID-19 vaccine can cause mild to moderate side effects. A number of cases of cardiac, gastrointestinal, and psychiatric side effects have been reported as rare side effects associated with the COVID-19 vaccine. This article presents a patient, who after the second injection of the mRNA-based COVID-19 vaccine, immediately developed anxiety, nonspecific fear, and insomnia as the prodromal phase of psychosis. Starting from the second week, the patient manifested delusions of persecution, delusions of influence, thoughts insertion, and delusional behaviour, culminating in the suicide attempt...

MATERIAL AND METHODS: One hundred and twenty-one patients with nosogenic reactions associated with CHF were examined. Somatic, clinical-psychopathological and psychometric examinations were used. RESULTS: Three types of nosogenic reactions in CHF have been identifiedSignificantly more frequent were dissociative reactions (76 (62...

This study aimed to investigate parents' PDs that could be associated with children and adolescents' EDs. We studied association of parental PDs with offspring EDs in age group 6-18 years in a nationally representative sample of Iranians with 27,111 children and adolescents and their parents. We used a multistage random cluster sampling method. We used Millon Clinical Multiaxial Inventory-Third Edition and Persian present and lifetime version of Kiddie Schedule for Affective Disorders and Schizophrenia to measure parental PDs and children and adolescents' EDs, respectively...

Schizophrenia is a chronic psychiatric disorder that classically presents with distortions of thought, behavior, and perceptions that are often misdiagnosed. One difficulty in diagnosing schizophrenia is due to its phenotypically heterogeneous condition that can be precipitated by a combination of genetic, epigenetic, and environmental factors. The prevalence of schizophrenia is roughly 1%, but it is often misdiagnosed. Possible differential diagnoses include depression or bipolar disorder with psychosis, psychosis due to a medical condition, schizotypal and schizoid personality disorders, and neurocognitive disorders...

Personality disorders can lead to difficult social or occupational functional processes rooted in chronic maladaptive thoughts, feelings, and behaviors. This study aimed to investigate factors of personality disorder in prisoners from the central prison of Sanandaj, Iran. We conducted a cross-sectional study, which included all prisoners in the central prison of Sanandaj, Iran. The study sample includes 343 prisoners, of which 329 were male, and 14 were female, selected by randomized multistage sampling method...

The current investigation asseses the relationship between DSM personality disorders (PDs) and PCL psychopathy in a community study: the Cambridge Study in Delinquent Development (CSDD). The children (Generation 3) of the original CSDD males (Generation 2) were assessed for PDs and psychopathy in early adulthood. Generation 3 consisted of both males ( n  = 291) and females ( n  = 260) and allowed for analyses separately for each gender. Cluster B PDs showed the strongest relationships with psychopathy, especially Borderline and Antisocial PD...

Background: With the implementation of the 11th edition of the International Classification of Diseases (ICD-11) in early 2022, there will be a radical change in the framework and process for diagnosing personality disorders (PDs), indicating a transition from the categorical to the dimensional model. Despite increasing evidence that PDs are not as stable as previously assumed, the long-term stability of PDs remains under major debate. The aim of the current paper was to investigate the categorical and dimensional mean-level and rank-order stability of PDs from adolescence into young adulthood in a high-risk sample...

Objective: School refusal (SR) in adolescence represents an important risk factor associated with adverse consequences. Although many clinical features of adolescents presenting with SR have been studied, the relationship between SR and personality styles-specifically in the help-seeking population-remains unclear. The present study aimed at investigating differences in personality style, adaptive functioning, and symptomology between Italian help-seeking adolescents who refused (SRa) and did not refuse (non-SRa) to attend school, to provide preliminary evidence of personality patterns in adolescent help-seekers presenting with SR...

OBJECTIVE: This study looked at the bright and dark-side personality profile of distressed and potentially derailing doctors (82% male). The derailing doctors were on average 48.75 years old, and from many specialities, in particular, general practice and surgery. METHOD: In all, a group of 77 derailing British doctors, and a control group of 357 doctors completed a valid multi-dimensional test of bright-side (normal) personality (NEO-PI-R) and one of dysfunctional interpersonal themes (sub-clinical personality disorders) (HDS: Hogan Development Survey)...

This essay provides the historical context and key findings of one of the largest fieldwork-based family studies ever done in the history of psychiatric genetics conducted in Berlin by Franz Kallmann from 1929 to 1933. It included over 1,000 schizophrenic probands and 12,500 of their relatives including siblings, offspring, nieces/nephews and grandchildren. The work was analyzed in close collaboration with Rüdin, Schulz, and Luxenburger in Munich. Born of Jewish parents, Kallmann had to leave Germany in 1936, completing and publishing the monograph in the United States in 1938...

BACKGROUND: Schizophrenia (SCH) and bipolar disorder (BD) have both shared and unique genetic risk factors and clinical characteristics. The aim of the present study was to identify potential risk factors significantly associated with SCH, relative to a BD reference group. METHODS: Data were obtained from medical records of patients that entered a major Mexico City hospital during 2009-2010 presenting psychotic symptoms (n = 1132; 830 cases of SCH, 302 cases of BD; 714 men and 418 women)...

Schizoid personality disorder (SZPD) is a Cluster A personality disorder whose essential feature is a lifelong pattern of detachment from social relationships and a restricted range of emotional expression. Although SZPD has been in every edition of the Diagnostic and Statistical Manual of Mental Disorders, empirical research on this disorder is actually limited, due to the fact that SZPD is rarely encountered in clinical settings. In fact, individuals with SZPD rarely present for treatment, as their isolation is often ego-syntonic; therefore, the prevalence of SZPD is not clearly established...

Risk of suicidal behaviour (SB) in schizophrenia spectrum disorders (SSD) is a major concern, particularly in early stages of the illness, when suicide accounts for a high number of premature deaths. Although some risk factors for SB in SSD are well understood, the extent to which personality traits may affect this risk remains unclear, which may have implications for prevention. We conducted a systematic review of previous studies indexed in MEDLINE, PsycINFO and Embase examining the relationship between personality traits and SB in samples of patients with SSD...

The assessment of schizotypy and schizophrenia-spectrum psychopathology has historically been adversely impacted by multiple forms of measurement bias, including racial bias. The Multidimensional Schizotypy Scale (MSS) was developed using modern scale construction methods to minimize measurement bias in the assessment of schizotypic traits. However, studies have not examined the validity of the measurement across different racial groups. The present study examined whether the associations of MSS positive, negative, and disorganized schizotypy subscales with interview-assessed ratings of functioning, schizophrenia-spectrum personality traits, and depressive disorders were generally comparable across nonclinically ascertained samples of Black (n = 46), Asian (n = 87), and White (n = 116) young adults...
