Obsessive-compulsive personality disorder (OCPD) has been subject to numerous definition and classification changes, which has contributed to difficulties in reliable measurement of the disorder. Consequently, OCPD measures have yielded poor validity and inconsistent prevalence estimates. Reliable and valid measures of OCPD are needed. The aim of the current study was to examine the factor structure and psychometric properties of the Pathological Obsessive Compulsive Personality Scale (POPS). Participants (N = 571 undergraduates) completed a series of self-report measures online, including the POPS...

Because stability over time is central to the definition of personality disorder, aim of the current study was to determine the stability of the Pregnancy Obsessive-Compulsive Personality Disorder (OCPD) Symptoms Checklist (N = 199 women). Strong positive correlations between assessments at 32 weeks of pregnancy and 2 and 3-3.5 years after childbirth were found (r between .62-.72), and the group mean score did not change over time. The Pregnancy OCPD Symptoms Checklist assesses stable, trait-like symptoms of OCPD...

In this work we developed new antibacterial composite materials using polydopamine (PDA) to trigger the deposition of silver nanoparticles (AgNPs) onto calcium phosphates, namely octacalcium phosphate (OCP) and α-tricalcium phosphate (αTCP). Functionalization of OCP and αTCP with a self-polymerized polydopamine layer was obtained by soaking the calcium phosphates in dopamine solution. The PDA surface of functionalized calcium phosphates (OCPd and αTCPd) promoted the deposition of AgNPs by reducing silver ions when soaked in a silver nitrate solution...

OBJECTIVE: Obsessive-compulsive personality disorder (OCPD) is formally operationalized in Section II of the DSM-5 by a heterogeneous collection of 8 categorical criteria. Section III contains an alternative model operationalizing personality disorders via dimensional personality traits and associated impairment. The extent to which the personality traits used to define OCPD in Section III correspond with the Section II operationalization of the disorder is contested. The current study aims to contribute to the evidence base necessary to solidify the optimal trait profile for this disorder via a more fine-tuned examination of OCPD...

In recent years, sparse representation based classification (SRC) is one of the most successful methods and has been shown impressive performance in various classification tasks. However, when the training data has a different distribution than the testing data, the learned sparse representation may not be optimal, and the performance of SRC will be degraded significantly. To address this problem, in this paper, we propose an optimal couple projections for domain-adaptive sparse representation-based classification (OCPD-SRC) method, in which the discriminative features of data in the two domains are simultaneously learned with the dictionary that can succinctly represent the training and testing data in the projected space...

Oxidation products of the poly-unsaturated fatty acids (PUFAs) arachidonic acid, α-linolenic acid and docosahexaenoic acid are bioactive in plants and animals as shown for the cyclopentenones prostaglandin 15d-PGJ2 and PGA2, cis-(+)-12-oxophytodienoic acid (12-OPDA), and 14-A-4 neuroprostane. In this study an inexpensive and simple enzymatic multi-step one-pot synthesis is presented for 12-OPDA, which is derived from α-linolenic acid, and the analogous docosahexaenoic acid (DHA)-derived cyclopentenone [(4Z,7Z,10Z)-12-[[-(1S,5S)-4-oxo-5-(2Z)-pent-2-en-1yl]-cyclopent-2-en-1yl] dodeca-4,7,10-trienoic acid, OCPD]...

BACKGROUND: Internet use is pervasive in many cultures. Little is known about the impact of obsessive-compulsive personality disorder (OCPD) symptoms on impulsive and compulsive psychopathologies in people who use the Internet. METHODS: Adult Internet users (N = 1,323) completed an online questionnaire quantifying OCPD symptoms, likely occurrence of select mental disorders (obsessive-compulsive disorder, attention-deficit/hyperactivity disorder [ADHD], problematic Internet use, generalized anxiety disorder), and personality questionnaires of impulsivity and compulsivity...

BACKGROUND: DSM-5 includes two conceptualizations of personality disorders (PDs). The classification in Section II is identical to the one found in DSM-IV, and includes 10 categorical PDs. The Alternative Model (Section III) includes criteria for dimensional measures of maladaptive personality traits organized into five domains. The degree to which the two conceptualizations reflect the same etiological factors is not known. METHODS: We use data from a large population-based sample of adult twins from the Norwegian Institute of Public Health Twin Panel on interview-based DSM-IV PDs and a short self-report inventory that indexes the five domains of the DSM-5 Alternative Model plus a domain explicitly targeting compulsivity...

INTRODUCTION: Obsessive-compulsive personality disorder (OCPD) has a pervasive pattern of preoccupation with orderliness, perfection, and mental and interpersonal control at the expense of flexibility, openness, and efficiency. The aims of the present study were to explore the relationship between OCPD and psychological stress and psychological tests. METHODS: We evaluated 63 OCPD patients and 107 healthy controls (HCs). We collected saliva samples from patients and controls before and after a social stress procedure, the Trier Social Stress Test (TSST), to measure the concentrations of salivary alpha-amylase (sAA) and salivary cortisol...

The current study examined the extent to which the trait-based operationalization of obsessive-compulsive personality disorder (OCPD) in Section III of the DSM-5 describes the same construct as the one described in Section II. A community sample of 313 adults completed a series of personality inventories indexing the DSM-5 Sections II and III diagnostic criteria for OCPD, in addition to a measure of functional impairment modelled after the criteria in Section III. Results indicated that latent constructs representing Section II and Section III OCPD overlapped substantially (r = ...

This study examined the association between self-reported obsessive-compulsive spectrum symptomatology and cognitive performance in a sample of patients with traumatic brain injury (TBI). Twenty-four adults with a moderate-severe TBI accessing a community brain injury rehabilitation service were recruited. Age ranged between 19 and 69 years. Participants completed a battery of neuropsychological tasks assessing memory, executive functioning, and speed of information processing. Self-report questionnaires assessing obsessive-compulsive (OC) symptoms and obsessive-compulsive personality disorder (OCPD) traits were also completed...

Obsessive-compulsive personality disorder (OCPD) is one of the most prevalent personality disorders, yet it remains an understudied phenomenon. Experiential avoidance (EA) has been investigated as a factor relevant in many forms of psychopathology, including borderline personality disorder. To date however, no study has yet investigated whether EA might also be relevant to OCPD. We administered a measure of EA and a multidimensional OCPD measure (assessing 5 OCPD trait dimensions and overall severity) to a large community sample (N = 571) as well as a group of individuals with self-identified OCPD features (N = 53)...

Obsessive-compulsive personality (OCPD) disorder is characterized by a pattern of excessive self-control, perfectionism and behavioral and cognitive rigidity. Despite the fact that OCPD is the most common personality disorder in the general population, published studies looking at the brain correlates of this disorder are practically nonexistent. The main goal of this study was to analyze the presence of brain alterations in OCPD when compared to healthy controls, specifically at the level of the Default Mode Network (DMN)...

Visual performance is considered as commanding modality in human perception. We tested whether Obsessive-compulsive personality disorder (OCPD) people do differently in visual performance tasks than people without OCPD. One hundred ten students of Ferdowsi University of Mashhad and non-student participants were tested by Structured Clinical Interview for DSM-IV Axis II Personality Disorders (SCID-II), among whom 18 (mean age = 29.55; SD = 5.26; 84% female) met the criteria for OCPD classification; controls were 20 persons (mean age = 27...

This study examined the validity of newly developed disorder-specific impairment scales (IS), modeled on the Level of Personality Functioning Scale, for obsessive-compulsive (OCPD) and avoidant (AvPD) personality disorders. The IS focused on content validity (items directly reflected the disorder-specific impairments listed in DSM-5 Section III) and severity of impairment. A community sample of 313 adults completed personality inventories indexing the DSM-5 Sections II and III diagnostic criteria for OCPD and AvPD, as well as measures of impairment in the domains of self- and interpersonal functioning...

Obsessive Compulsive Disorder (OCD) is a disorder with heterogeneous clinical presentations. To advance our understanding of this heterogeneity we investigated the prevalence and clinical features associated with incompleteness (INC), a putative underlying core feature of OCD. We predicted INC would be prominent in individuals with OCD and associated with greater severity and impairment. We examined the impact of INC in 307 adults with primary OCD. Participants with clinically significant INC (22.8% of the sample) had significantly greater OCD severity, greater rates of comorbidity, poorer ratings of functioning, lower quality of life, and higher rates of unemployment and disability...
