Schizoid personality disorder

INTRODUCTION: While the attention to personality disorders (PD) and childhood maltreatment (CM) has grown in recent years, there remains limited understanding of the prevalence and distinctions of PD and CM in clinical populations of Chinese adolescents in comparison to adults. METHODS: A total of 1,417 participants were consecutively sampled from patients diagnosed with either psychotic or non-psychotic disorders in the psychiatric and psycho-counseling clinics at Shanghai Mental Health Center...

Schizoid personality pathology is among the most debilitating and enigmatic forms of personality pathology. Some have suggested that a potential etiological influence on schizoid pathology is trauma. Thus far, research on the association between trauma and schizoid pathology has focused primarily on type of trauma (e.g., abuse vs. neglect during childhood) rather than who perpetrated the trauma. This contrasts with recent research on trauma perpetrated by someone upon whom the survivor relies and/or trusts (i...

Mental disorders with body-centered symptoms, such as somatic, eating, and body dysmorphic disorders, present difficulties in psychotherapy because psychological suffering is manifested in the body rather than expressed verbally. The present study illustrates a single case multi-method investigation sensitive to detecting characteristic change manifestations in the treatment of these disorders. We investigated a treatment of a patient with body dysmorphic disorder. Computerized linguistic measures were applied to 86 sessions to assess changes in symbolic processing; out of the 86 sessions, 40 were analyzed to calculate the proportion of speech focused on bodily symptoms versus on relationships...

The present case report describes a 19-year-old male patient whose main symptoms were emotional coldness, absence of close relationships, difficulty experiencing pleasure with other people, and lack of motivation to work or to continue his studies. A schizoid personality disorder was diagnosed as a product of early maladaptive patterns such as inhibition, emotional deprivation, social isolation, and inadequacy. Likewise, a rigid and fragmented family context was evidenced, with an affective absence of parents and a focus on strict behavioral rules...

BACKGROUND: Evidence suggests that there is substantial comorbidity between fibromyalgia and Axis II pathology (i.e., personality disorders-PDs). The aim of the current study was to find out the exact cluster (A, B, C) of PDs or traits that are more prominent in FM and may be predictors of FM diagnosis. METHODS: Data from 86 subjects (53 with FM and 33 controls without FM) were analyzed in an observational, cross-sectional, comparative study in a neurological setting...

OBJECTIVE: To study behavioral phenomena of depressive disorders in adolescence. MATERIAL AND METHODS: Ninety-five patients, aged 12 to 17 years, with a mixed disorder of emotions and behavior without cognitive impairment and psychotic disorders were examined. Clinical-psychopathological, clinical-follow-up methods, Beck scales, the Spielberger-Khanin scale, Zung and PDO questionnaires, statistical analysis were used. RESULTS: The structure of this syndrome included affective disorders: low mood ( n =84 88...

Avoidant personality disorder was introduced in DSM-III (American Psychiatric Association [APA], 1980), and debate persists regarding the utility of having two separate variants of the "detached personality." The present study addressed this issue through ratings of open-ended self-descriptions provided by community adults with high scores on schizoid versus avoidant personality traits ( N  = 229). The self-concept of individuals with avoidant personality style reflected a lack of positive self-regard and low self-efficacy/agency...

The current study sought to provide evidence for a measure of schizoid personality disorder (SZD PD) traits using the Five-Factor Model framework of personality. In the first study, undergraduate participants ( n = 496) completed the Five-Factor Schizoid Inventory (FFZI) and other self-report measures. The first half of the sample was used to develop the FFZI, while the second half was used to validate it. The FFZI demonstrated excellent internal consistency, convergent validity with measures of SZD PD and hypothesized IPIP-NEO facets, and discriminant validity with other PDs and non-hypothesized IPIP-NEO facets...

Schizophrenia stands as one of the most studied and storied disorders in the history of clinical psychology; however, it remains a nexus of conflicting and competing conceptualizations. Patients endure great stigma, poor treatment outcomes, and condemnatory prognosis. Current conceptualizations suffer from unstable categorical borders, heterogeneity in presentation, outcome and etiology, and holes in etiological models. Taken in aggregate, research and clinical experience indicate that the class of psychopathologies oriented toward schizophrenia are best understood as spectra of phenomenological, cognitive, and behavioral modalities...

Recent diagnostic developments suggest that paranoia is a transdiagnostic characteristic common to several personality disorders rather than a personality disorder per se. Nonetheless, empirical literature fails to provide comprehensive and univocal findings on whether and how paranoid presentations relate to different personality disorders. In the present scoping review, we map the empirical literature on paranoid presentations in personality disorders, considering the entire spectrum of paranoid manifestations (i...

This study evaluated the potential of ChatGPT, a large language model, to generate mentalizing-like abilities that are tailored to a specific personality structure and/or psychopathology. Mentalization is the ability to understand and interpret one's own and others' mental states, including thoughts, feelings, and intentions. Borderline Personality Disorder (BPD) and Schizoid Personality Disorder (SPD) are characterized by distinct patterns of emotional regulation. Individuals with BPD tend to experience intense and unstable emotions, while individuals with SPD tend to experience flattened or detached emotions...

Introduction: Inpatients with self-harm behavior utilize a high proportion of health care resources, and determining their suicide risk may be challenging. This study examines how maladaptive personality traits in people who self-harm are associated with suicide intent severity. Methods: This was a 5-month cross-sectional study. The International Personality Disorders Examination (IPDE) ICD-10 questionnaire, Beck's Suicide Intent Scale (SIS), and the Depression Anxiety Stress Scale (DASS) 21 were administered...

OBJECTIVE: The schema mode model offers a new conceptualisation of complex dissociative disorders (CDD) as it explains shifts between identities as shifts between schema modes. Furthermore, in this model CDD is conceived as personality pathology, incorporating core features of personality disorders. This study tested the assumptions of this schema mode model of CDD. METHOD: Questionnaires measuring personality disorder traits, schemas, schema modes and coping styles were filled out by patients with CDD, borderline personality disorder and avoidant personality disorder (N = 210), and their scores on the various constructs were compared...

Schizophrenia has been associated with premorbid poor educational performance and low educational attainment (EA). However, some studies have found positive associations between psychotic disorders and excellent scholastic performance. In the present study, we examined the association between EA and several clinical and nonclinical characteristics in psychiatric patients diagnosed with psychotic or bipolar disorders. Data were obtained from the files of 1132 patients who entered a major Mexico City psychiatric hospital during the years 2009-2010 for the treatment of psychotic symptoms and who were subsequently diagnosed with schizophrenia, bipolar, schizoaffective, or another psychotic disorder...

BACKGROUND: The present study evaluates personality traits in adult patients with cystic fibrosis (CF) and correlates these results with health-related quality of life (HRQoL) and other clinical parameters indicative of disease severity. METHODS: Seventy adults completed the Cystic Fibrosis Questionnaire-Revised (CFQ-R 14+), a CF-specific measure of HRQoL, and a self-administered questionnaire about personality traits and disorders. Mean subscale scores and the prevalence of extreme personality traits on the `Persönlichkeits-Stil- und Störungs-Inventar (PSSI)´ were compared to the norming sample...

The aim of this systematic review and meta-analysis was to investigate the diagnostic, the dimensional mean-level, and rank-order stability of personality disorders (PDs) and PD criteria over time. EMBASE, PsycInfo, PubMed, and Web of Science were searched for peer-reviewed studies published in either English, German, or French between the first publication of the third edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-III) in 1980 and December 20, 2022. Inclusion criteria were a prospective longitudinal study design, assessing the stability of PDs or PD criteria over at least two measurement occasions at least one month apart, and using the same assessment at baseline and follow-up...

INTRODUCTION: Cluster headache (CH) is usually comorbid to mood spectrum disorders, but the psychopathological aspects are poorly explored. We aimed at identifying discrete profiles of personality traits and their association with clinical features. METHODS: Based on the personality scales of the Millon Clinical Multiaxial Inventory-III, principal component analysis (PCA) identified psychological patterns of functioning of 56 CH patients. PCA outcomes were used for hierarchical cluster analysis (HCA) for sub-groups classification...

On September 27, 1922, Ernst Rüdin gave an address to the Annual Conference of the German Society of Genetics entitled "Regarding the Heredity of Mental Disturbances." Published in a 37-page article, Rüdin reviewed the progress in the field of Mendelian psychiatric genetics, then hardly more than a decade old. Topics included (a) the status of Mendelian analyses of dementia praecox and manic-depressive insanity which had expanded to include two and three locus and early polygenic models and sometimes included, respectively, schizoid and cyclothymic personalities; (b) a critique of theories for the explanation of co-occurrence of different psychiatric disorders within families; and (c) a sharp methodologic critique of Davenport and Rosanoff's contemporary work which emphasized Rüdin's commitment to careful, expert phenotyping, a primary focus on well-validated psychiatric disorders and not broad spectra of putatively inter-related conditions, and an emphasis on rigorous statistical modeling as seen in his continued collaboration with Wilhelm Weinberg...

AIM: Interpersonal sensitivity and mistrust are the main characteristics of cluster A personality disorders (CAPD) which might be due to the high accessibility to negative suggestions from environments. Yet the exact associations between hypnotic suggestibility and their personality disorder functioning styles remain unclear. METHODS: We invited 36 patients with CAPD and 115 healthy volunteers to undergo the Stanford Hypnotic Susceptibility Scale: Form C (SHSS:C) and Parker Personality Measure (PERM)...

BACKGROUND: Sex-related disturbance including sexual dreams contributes to psychiatric disorders, but whether personality disorder functioning styles are linked with sexual dreams especially in frequent dreamers remains unsettled SUBJECTS AND METHODS: One hundred and seventy one healthy volunteers (controls) and 81 frequent sexual dreamers (fsDreamers) were invited to answer the Sexual Dream Experience Questionnaire (SDEQ) and the Parker Personality Measure (PERM). RESULTS: Compared to controls, fsDreamers scored significantly higher on SDEQ Joyfulness, Familiarity, Bizarreness and the annual frequency, and on all PERM styles except Schizoid and Obsessive-Compulsive...
