Study of Obsessive Compulsive Beliefs: Relationship with Eating Disorders
2011
Background: The relationship between Eating Disorders (ED) and Obsessive Compulsive Disorder (OCD) has been extensively studied in the last few years. However, little effort has been devoted to studying the link between these disorders with regard to their distorted beliefs. Aims: The first objective of the study was to analyze the differences in OCD-related beliefs among ED subtypes and the general population, controlling for age, Body Mass Index, and obsessionality. The second objective was to explore which OCD beliefs explain ED symptomatology. Method: Seventy-nine ED patients without OCD comorbidity, divided into diagnostic subtypes, and 50 community participants completed the Obsessive…
Identification of two novel polymorphisms and a rare deletion variant in the human dopamine D4 receptor gene
1995
We report two novel polymorphisms and a rare deletion variant in the human dopaine D4 receptor gene. The two polymorphisms are characterized by single base pair substitutions, namely a G-->C transversion changing codon 11 from GGG (encoding Gly) to CGG (encoding Arg) and a C-->T transition in position -11 upstream from the start codon. The Arg11 variant occurs at a frequency of about 1% and the C-->T transition at a frequency of about 7% in German control subjects (n = 148). Allele frequencies observed in patients suffering from schizophrenia (n = 256) and bipolar affective disorder (n = 99) were similar. The deletion variant is characterized by a 21 bp deletion affecting codons 36 to 42 co…
Break in volition: a virtual reality study in patients with obsessive-compulsive disorder.
2013
Research in obsessive-compulsive disorder (OCD) produced inconsistent results in demonstrating an association between patients’ symptom severity and their cognitive impairments. The process involved in volition aspects of behavioral syndromes can be extensively analyzed using specific tests developed in virtual environments, more suitable to manipulate rules and possible breaks of the normal task execution with different, confusing or stopping instructions. The study involved thirty participants (15 OCD patients and 15 controls) during task execution and the relative interferences. At this purpose, the virtual version of Multiple Errands Test was used. Virtual reality setting, with a higher…
Cognitive assessment of OCD patients: Neurovr vs neuropsychological test
2014
This study aimed to evaluate the reliability and validity of the Neuro- Virtual Reality as tool for the neuropsychological assessment in OCD patients. We used the neuropsychological battery and a virtual version of the Multiple Errand Test (V-MET), developed using the NeuroVR software, in order to evaluate the executive functions, the ability to plan ahead on complex problem solving tasks in daily life in 30 obsessive compulsive disorder (OCD) patients and 30 healthy controls. The results showed the presence of difficulties of OCD patients: lower levels of divided attention and higher levels of errors; higher mean rank of inefficiencies, interpretation failures and rule breaks and longer ti…
Consequências mal adaptativas de invasões mentais com conteúdos relacionados a transtornos obsessivos, dismórficos, hipocondríacos e alimentares: dif…
2021
Unwanted mental intrusions (UMIs) with contents related to Obsessive-Compulsive Disorder (OCD), Body Dysmorphic Disorder (BDD), Illness Anxiety Disorder (IAD), and Eating Disorders (EDs) are highly prevalent, independently of the cultural and/or social context. Cognitive-behavioral explanations for these disorders postulates that the escalation from common UMIs to clinically relevant symptoms depends on the maladaptive consequences (i.e., emotions, appraisals, and control strategies) of experiencing UMIs. This study examines, from a cross-cultural perspective, the cognitive-behavioral postulates of the maladaptive consequences of having UMIs.Non-clinical 1,473 participants from Europe, the …
Decision Making and Cognitive Behavioral Flexibility in a OCD Sample: a Study in a Virtual Environment
2015
Neuropsychological disorders are common in Obsessive-Compulsive Disorder (OCD) patients. Executive functions, verbal fluency and verbal memory, shifting attention from one aspect of stimuli to others, mental flexibility, engaging in executive planning and decision making, are the most involved cognitive domains. We focus on two aspects of neuropsychological function: decision making and cognitive behavioral flexibility, assessed through a virtual version of the Multiple Errand Test (V-MET), developed using the NeuroVR software.Thirty OCD patients were compared with thirty matched control subjects. The results showed the presence of difficulties in OCD patients with tasks where the goal is n…
Factors associated with non-treatment or delayed treatment seeking in OCD sufferers: a review of the literature.
2013
Obsessive-compulsive disorder (OCD) is a disabling disorder that can be successfully treated. However, a high percentage of sufferers neither ask for nor receive treatment for their symptoms, or they delay seeking treatment. The factors underlying the treatment-seeking behaviour of OCD patients are still not clear. This review includes 12 studies published before April 2014 that analyse the possible variables related to the delayed help-seeking behaviour of OCD patients. Studies showed that individuals who asked for help were more impaired and reported poorer quality of life. Help-seeking behaviour was associated with greater insight, severity, specific obsessive-compulsive symptoms, such a…
La evaluación del perfeccionismo: utilidad de la Escala Multidimensional de Perfeccionismo en población española
2009
La Escala Multidimensional de Perfeccionismo (MPS) de Frost et al. (1990) es uno de los instrumentos con más tradición empírica y mayor influencia en el estudio del perfeccionismo. El objetivo de este trabajo es traducir y validar la MPS para su uso en población española. Para ello, 434 participantes (77% mujeres; edad media: 23,38 años), completaron la versión española de la MPS junto con cuestionarios de obsesividad, trastornos alimentarios, y preocupaciones ansiosas, para evaluar la validez convergente de la MPS. El análisis de componentes principales (varianza explicada: 56%), reveló una estructura de 4 factores en lugar de los 6 originales: Miedo a los errores, Influencias paternas, Ex…
Treatments used for obsessive-compulsive disorder-An international perspective.
2018
Objective The objective of this study was to characterise international trends in the use of psychotropic medication, psychological therapies, and novel therapies used to treat obsessive–compulsive disorder (OCD). Methods Researchers in the field of OCD were invited to contribute summary statistics on the characteristics of their samples. Consistency of summary statistics across countries was evaluated. Results The study surveyed 19 expert centres from 15 countries (Argentina, Australia, Brazil, China, Germany, Greece, India, Italy, Japan, Mexico, Portugal, South Africa, Spain, the United Kingdom, and the United States) providing a total sample of 7,340 participants. Fluoxetine (n = 972; 13…
Can Brief, Daily Training Using a Mobile App Help Change Maladaptive Beliefs? Crossover Randomized Controlled Trial
2019
BackgroundObsessive-compulsive disorder (OCD) is a disabling condition with a wide variety of clinical presentations including contamination fears, fear of harm, and relationship-related obsessions. Cognitive behavioral models of OCD suggest that OC symptoms result from catastrophic misinterpretations of commonly occurring intrusive experiences and associated dysfunctional strategies used to manage them. OCD-related maladaptive beliefs including inflated responsibility, importance and control of thoughts, perfectionism, and intolerance for uncertainty increase the likelihood of such misinterpretations. ObjectiveConsidering accumulating evidence suggesting that mobile health (mHealth) apps b…
