OBJECTIVE: This study aimed to develop and validate the Distress Tolerance Scale-Short Form (DTS-SF), a modification of the original Distress Tolerance Scale, in a severe/complex sample of individuals with obsessive compulsive disorder (OCD). Currently, there are multiple self-report measurements of distress tolerance (DT), highlighting the need for a more refined measure. METHOD: Participants included 222 individuals with a primary diagnosis of OCD (57% male, average age = 31) seeking intensive/residential treatment...

Gambling disorder affects approximately 1.1-3.5% of the population, with the rates being higher in young adults. Despite this high prevalence, little is known regarding which pathological gamblers decide to seek treatment. This study sought to examine the differences in three groups of pathological gamblers: those who did not seek treatment (n = 94), those who sought therapy (n = 106) and those who sought medication therapy (n = 680). All subjects were assessed on a variety of measures including demographics, family history, gambling history, comorbid psychiatric disorders and an assortment of clinical variables such as the Quality of Life Inventory, Hamilton Depression and Anxiety Rating Scales, Yale Brown Obsessive Compulsive Scale for Pathologic Gambling (PG-YBOCS), Barratt Impulsiveness Scale, Eysenck Impulsiveness Questionnaire and select cognitive tasks...

The association between obsessive-compulsive disorder (OCD) and Tourette's/chronic tic disorders (TD/CTD) with autoimmune diseases (ADs) is uncertain. In this nationwide study, we sought to clarify the patterns of comorbidity and familial clustering of a broad range of ADs in individuals with OCD, individuals with TD/CTD and their biological relatives. From a birth cohort of 7 465 455 individuals born in Sweden between 1940 and 2007, we identified 30 082 OCD and 7279 TD/CTD cases in the National Patient Register and followed them up to 31 December 2013...

BACKGROUND: Ethological methods used to analyze human obsessive-compulsive disorder (OCD) rituals demonstrated excess of unnecessary repetitions as well as irrelevant, idiosyncratic acts (additions) compared to normal activity. A question that still remains is whether these well-known repetitions and additions are manifested in behaviors unrelated to the OCD rituals. Our objectives were to: (1) assess whether OCD-related repetitions and additions as found in previous studies also affect the patients' activity of filling out questionnaires and (2) evaluate the specificity of these behaviors to OCD as opposed to other anxiety disorders and healthy controls...

These case reports focus on a rapid treatment for persistent complex bereavement disorder and posttraumatic stress disorder (PTSD), which appears to activate the mirror neuron network. Simulated reattachment is a technique which has been found to repair phantom limb pain in just a few sessions. The same neuroplasticity that accomplishes phantom pain relief has been found to occur in the treatment of complicated grief and PTSD using similar methods. The simulated reattachment for the client in Case one was found to significantly reduce the symptoms of both complicated grief and obsessive-compulsive disorder (OCD) within one session...

People with obsessive-compulsive disorder [OCD] frequently suffer from depression, a comorbidity associated with greater symptom severity and suicide risk. We examined the associations between OCD and depression symptoms in 87 adolescents with primary OCD. We computed an association network, a graphical LASSO, and a directed acyclic graph (DAG) to model symptom interactions. Models showed OCD and depression as separate syndromes linked by bridge symptoms. Bridges between the two disorders emerged between obsessional problems in the OCD syndrome, and guilt, concentration problems, and sadness in the depression syndrome...

The retrospective and subjective nature of clinical interviews is an important shortcoming of current psychiatric diagnosis. Consequently, there is a clear need for objective and standardized tools. Virtual reality (VR) can be used to achieve controlled symptom provocation, which allows direct assessment for the clinician. We developed a video VR game to provoke and assess obsessive-compulsive disorder (OCD) symptoms in a standardized and controlled environment. The first objective was to evaluate if the VR game is capable of provoking symptoms in OCD patients as opposed to healthy controls...

The purpose of this study was to evaluate the impact of changes in perceptions about patient volume and severity of clinical presentations in university counseling centers (UCCS) on burnout. It was hypothesized that perceptions of increased workload and severity of conditions treated would be positively correlated with burnout. It was also hypothesized that self-reported use of evidence-based practice (EBP) would be negatively correlated with burnout. Counseling center clinicians (n = 80) completed the Copenhagen Burnout Inventory (CBI), the Evidence-Based Practice Attitudes Scale (EPBAS), and reported on factors that have been shown to impact burnout...

BACKGROUND: Obsessive-compulsive disorder (OCD) symptoms within the context of a bipolar disorder (BD) have been described since the 19th century. Interestingly, the existence of a relevant overlap between the aforementioned psychiatric syndromes has been confirmed by a number of recent epidemiological and family studies. AIMS: The aim of the present paper is to review the clinical features and the therapeutic implications of the OCD-BD comorbidity. DISCUSSION: In the last two decades, the frequent association between OCD and BD has been earning a growing interest given its relevant nosological and therapeutic implications...

BACKGROUND: In the last decades the pharmacological treatment of obsessive-compulsive disorder (OCD) has been significantly promoted by the effectiveness of selective serotonin (5-HT) reuptake inhibitors (SSRIs) and the subsequent development of the 5-HT hypothesis of OCD. However, since a large majority of patients (between 40% and 60 %) do not respond to SSRIs or strategies based on the modulation of the 5-HT system, it is now essential to search for other possible therapeutic targets...

Little is known about the natural history of children with pediatric autoimmune neuropsychiatric disorder associated with streptococcal infections (PANDAS). This study prospectively followed 33 children with PANDAS for up to 4.8 years (mean 3.3 ± 0.7 years) after enrollment in a 24-week randomized, double-blind, placebo-controlled trial of intravenous immunoglobulin (IVIG) (N = 35). Fourteen of eighteen children randomized to placebo received open label IVIG 6 weeks after the blinded infusion, so follow-up results reported below largely reflect outcomes in a population of children who received at least one dose of IVIG...

OBJECTIVE: Emotion regulation difficulties are implicated in psychological disorders but their role in obsessive-compulsive disorder (OCD) is unclear. Two studies examining these difficulties in OCD are presented. METHOD: A community sample (Study 1; n = 306) and a clinical OCD sample (Study 2; n = 59) completed the Difficulties in Emotion Regulation Scale (DERS) and measures of depression, anxiety, and OCD. In Study 2, the OCD sample was compared to a matched control group (n = 59, selected from Study 1)...

BACKGROUND: Pediatric autoimmune neuropsychiatric disorders associated with streptococcal infections (PANDAS) are immune-mediated diseases characterized by obsessive-compulsive symptoms and/or tics triggered by group A Streptococcus infections. Despite the well-known action of 25-hydroxyvitamin D [25(OH)D] on different conditions driven by systemic inflammation, there are no data about the 25(OH)D status in patients with PANDAS. AIMS: To evaluate plasma 25(OH)D levels in a large cohort of children and adolescents with PANDAS and comparing the results with healthy controls...

Aberrant cortical-striatal-thalamic-cortical circuits have been implicated in the pathophysiology of obsessive-compulsive disorder (OCD). However, the neurobiological basis of OCD remains unclear. We compared patterns of functional connectivity in patients with OCD and in healthy controls using resting-state magnetoencephalography (MEG). Participants comprised 24 patients with OCD (21 men, 3 women) and 22 age- and sex-matched healthy controls (19 men, 3 women). Resting-state measurements were obtained over a 6-min period using a 152-channel whole-head MEG system...

Davide Bossoli, Matteo Bottai
Dependent data arise frequently in applied research and several approaches to adjusting for the dependence among observations have been proposed in quantile regression. Cluster bootstrap is generally inefficient and computationally demanding, especially when the number of clusters is large. When the primary interest is on marginal quantiles, estimating equations have been proposed that estimate a working correlation matrix from the regression residuals' sign. However, the Pearson's correlation coefficient is an inadequate measure of dependence between binary variables because its range depends on their marginal probabilities...
