The oxytocin receptor (OXTR) is a potential candidate in the pathophysiology of obsessive-compulsive disorder (OCD). The present study investigated the association between common single-nucleotide polymorphism (SNPs) of the OXTR gene and the affected status of OCD or distinct clinical subtypes of OCD including the age at onset and symptom dimensions. Ten SNPs of OXTR were examined in 615 patients with OCD and 581 healthy controls. Single-marker and haplotype-based association analyses were conducted. While OXTR variants were not associated with the affected status of OCD or its clinical symptom dimensions, rs2268493 (p=0...

BACKGROUND: Obsessive-compulsive disorder (OCD) is a condition which can have major effects on the life of both the sufferer and their family members. Previous research has shown that the impact of illness on family members is related to their conceptualisation of the illness. In the present study we used qualitative methods to explore illness perceptions in family members of people with OCD. METHOD: Fourteen family members of people meeting diagnostic criteria for OCD within the previous year took part in a semi-structured interview...

Obsessive compulsive disorder (OCD) is associated with a moderate degree of underperformance on cognitive tests, including deficient processing speed. However, despite little research focusing on Intelligence Quotient (IQ) in OCD, it has long been speculated that the disorder is associated with elevated intellectual capacity. The present meta-analytic study was, therefore, conducted to quantitatively summarize the literature on IQ in OCD systematically. We identified 98 studies containing IQ data among individuals with OCD and non-psychiatric comparison groups, and computed 108 effect sizes for Verbal IQ (VIQ, n = 55), Performance IQ (PIQ, n = 13), and Full Scale IQ (FSIQ, n = 40)...

The clinical surveillance and active management of Tourette syndrome (TS) and other primary chronic tic disorders cannot be limited to tics, as these patients manifest a spectrum of sensory-, behavioral-, cognitive-, and sleep-related problems that have a major impact on their functioning and quality of life, influencing enormously clinical decision making on a routine basis. The sensory phenomena of primary tic disorders consist of premonitory urges and heightened sensitivity to external somatosensory and interoceptive stimuli...

Obsessive-compulsive disorder (OCD) is a common psychiatric disorder with a lifetime prevalence of 2-3%. Recently, brain activity in the resting state is gathering attention for exploring altered functional connectivity in psychiatric disorders. Although previous resting-state functional magnetic resonance imaging studies investigated the neurobiological abnormalities of patients with OCD, there are concerns that should be addressed. One concern is the validity of the hypothesis employed. Most studies used seed-based analysis of the fronto-striatal circuit, despite the potential for abnormalities in other regions...

Obsessive-compulsive disorder (OCD) is a chronic disabling disorder characterized by recurrent obsessions and uncontrolled compulsions. Recent research on anxiety disorders suggests that manual-guided short-term psychodynamic therapy (STPP) may be a promising approach. Building on this, a model of STPP for OCD was developed based on Luborsky's supportive-expressive (SE) therapy. Treatment consists of 12 modules, which include the characteristic elements of SE therapy, that is, a focus on the Core Conflictual Relationship Theme (CCRT) associated with OCD symptoms and on establishing a secure alliance...

The aim of this study was to investigate a new measure, the Wetterneck-Hart OCD Screener (WHOS), as a self-report screening tool for obsessive-compulsive disorder (OCD). The authors examined relationships between the WHOS and severity scores of OCD measures taken via three methods of data collection: online, at OCD consumer conferences, and from an intensive, residential OCD program. Severity measures included the Yale-Brown Obsessive-Compulsive Scale-Self Report (Y-BOCS-SR), the Dimensional Obsessive-Compulsive Scale (DOCS), and the Obsessive-Compulsive Inventory-Revised (OCI-R)...

The current literature provides substantial evidence of brain alterations associated with obsessive-compulsive disorder (OCD) symptoms (eg, checking, cleaning/decontamination, counting compulsions; harm or sexual, symmetry/exactness obsessions), and emotional problems (eg, defensive/appetitive emotional imbalance, disgust, guilt, shame, and fear learning/extinction) and cognitive impairments associated with this disorder (eg, inhibitory control, working memory, cognitive flexibility). Building on this evidence, new clinical trials can now target specific brain regions/networks...

BACKGROUND: Error monitoring, cognitive control and motor inhibition control are proposed as cognitive alterations disrupted in obsessive-compulsive disorder (OCD). OCD has also been associated with an increased sensitivity to social evaluations. The effect of a social simulation over electrophysiological indices of cognitive alterations in OCD was examined. METHODS: A case-control cross-sectional study measuring event-related potentials (ERP) for error monitoring (Error-Related Negativity), cognitive control (N2) and motor control (LRP) was conducted...

BACKGROUND: Default mode network (DMN), central executive network (CEN) and salience network (SN) are the three most important intrinsic networks of the human brain. Recent studies emphasized the importance of the "triple-network model" which illustrated the interactions within and between DMN, CEN and SN in the pathophysiology of psychiatric disorders. However, previous studies of obsessive-compulsive disorder (OCD) just explored the altered connectivity within these networks while neglected the coupling between them...

Global field synchronization (GFS) quantifies the synchronization level of brain oscillations. The GFS method has been introduced to measure functional synchronization of EEG data in the frequency domain. GFS also detects phase interactions between EEG signals acquired from all of the electrodes. If a considerable amount of local brain neurons has the same phase, these neurons appear to interact with each other. EEG data were received from 17 obsessive-compulsive disorder (OCD) patients and 17 healthy controls (HC)...

Studies have suggested that stigma resistance plays an important role in the recovery from mental illness. However, there has been limited research in Asian countries that has examined the benefits of stigma resistance among the mentally ill in Asian populations. Hence, this study aimed to assess the prevalence of stigma resistance and establish the socio-demographic correlates of stigma resistance, as well as its association with internalised stigma and psychosocial outcomes among a multi-ethnic population of 280 outpatients with obsessive compulsive disorder (OCD), schizophrenia, depressive disorders and anxiety disorders in Singapore...

BACKGROUND: Research on the utility of structured interviews in assessing OCD is scarce, and even more so, in its use for OCD in African Americans. The purpose of this study was to examine the utility of the Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I) in detecting OCD in African Americans when used by well-trained, culturally competent clinicians. METHODS: Seventy-four African American adults with OCD were assessed with the SCID-I and additional measures of OCD...

OBJECTIVE: Exposure and response prevention (ERP) is an effective treatment for individuals with obsessive-compulsive disorder (OCD), yet a substantial number of individuals with OCD do not fully respond to this intervention. Based on emerging experimental and clinical research on acceptance, this study sought to explore whether willingness to experience unpleasant thoughts, emotions, and bodily sensations during ERP was associated with improved treatment response. METHODS: Two hundred eighty-eight adults with OCD receiving residential ERP provided self-rated willingness and other exposure-related variables during each daily coached ERP session...

Pathological fear and anxiety regarding food, eating, weight and body shape are at the core of eating disorder (ED) psychopathology. To manage anxiety, patients develop complicated repertoires of ritualistic and repetitive behaviours, which can lead to total functional impairment. Yet the cognitive processes underlying anxiety, fear, and anxiety-driven behaviours in EDs remain poorly understood. Intolerance of Uncertainty (IU) is defined as a tendency to react negatively on an emotional, cognitive, and behavioural level to uncertain situations and events...

BACKGROUND: serotonin reuptake inhibitors (SRIs) and cognitive-behavioral psychotherapy (CBT) are first-line treatments for obsessive-compulsive disorder (OCD). Since response is often inadequate, in recent years researchers investigated whether combining CBT and SRIs, either ab initio or sequentially, results in a greater reduction of obsessive-compulsive symptoms. OBJECTIVE: the aims of the present paper are to assess if combination treatment seems adding benefits as compared to either monotherapy alone and if sequential strategies may be effective in converting partial or non responders to a first-line treatment into responders...

BACKGROUND: Depression and anxiety are routinely screened as part of perinatal care. However, other Axis 1 disorders and specific anxiety disorders are less likely to be screened or assessed as part of obstetric care. The objective of this study was to determine whether the Psychiatric Diagnostic Screening Questionnaire (PDSQ) is a potentially useful tool to screen for psychiatric conditions in pregnant and postpartum women in a community setting. METHODS: We compared the prevalence of DSM Axis I disorders obtained on the PDSQ with: (1) the prevalence of these disorders reported in previous studies of pregnant and postpartum women, and (2) scores obtained on the Edinburgh Postpartum Depression Scale (EPDS) and the Symptom Checklist-90-Revised (SCL-90R) anxiety scale...

Experimental research has shown that conditioned disgust is resistant to extinction, which may account for the slower habituation to disgust relative to fear in contamination-based obsessive-compulsive disorder (OCD). However, few studies have examined the efficacy of interventions that may attenuate conditioned disgust responses. Studies of cognitive reappraisal have demonstrated that reinterpreting a stimulus can alter emotional responding. This technique is based on cognitive theories which suggest that anxiety disorders arise from biased cognitions; therefore, changing a person's thoughts will elicit durable changes in emotional responses...

Illness anxiety and OCD symptoms appear to overlap in their presentation as well as in other conceptually important ways (e.g., dysfunctional cognitions). Little research, however, has directly examined these putative relationships. The present study examined the extent to which illness anxiety symptoms were associated with OCD symptom dimensions and relevant cognitive factors in a large treatment-seeking sample of patients with OCD. Patients completed a battery of self-report measures of OCD and health anxiety symptoms and related cognitive biases...

BACKGROUND: The Obsessive-Compulsive Treatment Efficacy randomised controlled Trial emerged from a research recommendation in National Institute for Health and Care Excellence obsessive-compulsive disorder (OCD) guidelines, which specified the need to evaluate cognitive-behavioural therapy (CBT) treatment intensity formats. OBJECTIVES: To determine the clinical effectiveness and cost-effectiveness of two low-intensity CBT interventions [supported computerised cognitive-behavioural therapy (cCBT) and guided self-help]: (1) compared with waiting list for high-intensity CBT in adults with OCD at 3 months; and (2) plus high-intensity CBT compared with waiting list plus high-intensity CBT in adults with OCD at 12 months...
