Research findings into the causes of OCD are reviewed which indicate that the brains of individuals with OCD have different patterns of brain activity than those of people without mental illness or with some other mental illness. Other types of illness that may be linked to OCD are noted, such as Tourette syndrome, trichotillomania, body dysmorphic disorder and hypochondriasis. The use of pharmacotherapy and behavior therapy to treat individuals with OCD is evaluated and a screening test for OCD is presented, along with information on how to get help for OCD. Lists of organizations that can be contacted and related books on the subject are also provided. Case histories of people with OCD are included in the margins of the booklet.

A Dissertation submitted to the Faculty of the Graduate School, Marquette University, in Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy Milwaukee, Wisconsin August, 2011 ABSTRACT OCD AS A DYNAMICAL DISEASE AND THE FAMILIAL CONTEXT OF RITUAL RIGIDITY: A NONLINEAR DYNAMICS PERSPECTIVE Robert W. Bond, Jr., B.S., M.S. Marquette University, 2011 Comparatively few studies of obsessive-compulsive disorder (OCD) have addressed the interpersonal dynamical patterns within families that could exacerbate or quell symptom severity in the ill relatives or hypothesize other roles for familial variables. Furthermore, the extant studies have relied primarily upon linear models. Methodological limitations of linear models, such as assuming that change occurs as the result of unidirectional influences and that the scores obtained for each variable are independent of each other are at variance with temporal, dynamic phenomena and have restricted the empirical investigations of the dynamics of OCD. The current study investigated whether OCD could be considered a dynamical disease such that the complex rhythmic processes that are the norm for living things would be replaced by relatively constant dynamics or by periodic dynamics.

Hood Psychology Ryerson University The purpose of this study was to examine the cognitive and neuropsychological constructs that are conceptually related to poor insight in obsessive-compulsive disorder (OCD). The relationship between dimensions of insight (Brown Assessment of Beliefs Scale; BABS) and cognitive (magical thinking, paranoia/suspiciousness), metacognitive (metacognition, decentering, cognitive flexibility), and neuropsychological indices of cognitive flexibility were examined. Participants with OCD (N = 80) referred for treatment at an outpatient anxiety disorders clinic completed a clinical interview, a brief battery of neuropsychological measures, and a computer-administered questionnaire package assessing the variables of interest.

E-mail: [email protected] ABSTRACT Compulsive behaviors are driven by repetitive urges and typically involve the experience of limited voluntary control over these urges, a diminished ability to delay or inhibit these behaviors, and a tendency to perform repetitive acts in a habitual or stereotyped manner. Compulsivity is not only a central characteristic of obsessive-compulsive disorder (OCD) but is also crucial to addiction. Based on this analogy, OCD has been proposed to be part of the concept of behavioral addiction along with other non-drug-related disorders that share compulsivity, such as pathological gambling, skin-picking, trichotillomania and compulsive eating.

  • Self-Ambivalence in Obsessive-Compulsive Disorder
    Self-Ambivalence in Obsessive-Compulsive Disorder Sunil S Bhar Submitted in total fulfilment of the requirements of the degree of Doctor of Philosophy July, 2004 Produced on acid-free paper Department of Psychology University of Melbourne ii iii Abstract According to the cognitive model, Obsessive-compulsive disorder (OCD) is maintained by various belief factors such as an inflated sense of responsibility, perfectionism and an overestimation about the importance of thoughts. Despite much support for this hypothesis, there is a lack of understanding about the role of self-concept in the maintenance or treatment of OCD. Guidano and Liotti (1983) suggest that individuals who are ambivalent about their self-worth, personal morality and lovability use perfectionistic and obsessive compulsive behaviours to continuously restore self- esteem. This thesis develops a model of OCD that integrates self-ambivalence in the cognitive model of OCD. Specifically, it explored the hypothesis that the OCD symptoms and the belief factors related to the vulnerability of OCD are mechanisms that provide relief from self- ambivalence. It addressed three questions. First, is self-ambivalence related to OCD symptoms and OCD-related beliefs? Second, to what extent is self-ambivalence specific to OCD, compared to other anxiety disorders? Third, to what extent is self-ambivalence important in accounting for response and relapse of OCD to psychological interventions? In order to explore these questions, a questionnaire measuring self- ambivalence was first developed and evaluated. Non clinical and clinical participants were recruited for research. Non-clinical participants (N = 269) comprised undergraduate students (N = 226: mean age = 19.55; SD = 3.27) and community controls (N = 43; mean age = 43.78; SD = 3.92).

Cognitive theories of OCD assume that the interpretation of normal intrusive thoughts leads to the development and maintenance of the disorder. Research that supports the role of beliefs and appraisals in maintaining distress in OCD is based on the supposition that clinical obsessions are comparable to normal intrusive thoughts. This paper reviews research investigating the occurrence of intrusive thoughts in a non-clinical population, in order to assess if these thoughts are comparable to obsessions.

INHIBITION IN OBSESSIVE COMPULSIVE DISORDER 1 Abstract Obsessive compulsive disorder (OCD) is characterized by intrusive, anxiety-provoking obsessions and irresistible compulsions that are performed to relieve anxiety. It is theorized that a deficit in inhibition may play a role in obsessive-compulsive symptomology. Areas of cognitive functioning that are affected by inhibition deficits may lead to obsessions and intrusive thoughts, while behavioral inhibition deficits may lead to compulsions. In the current paper, inhibition is examined in individuals with OCD, how such a deficit affects attention, recall, and response control, and how this relates to the disorder’s symptoms. A better

Fontenelle11,12,13 & Murat Yücel11 Received: 22 January 2018 /Accepted: 27 March 2019 /Published online: 23 April 2019 # The Author(s) 2019 Abstract Compulsive tendencies are a central feature of problematic human behavior and thereby are of great interest to the scientific and clinical community. However, no consensus exists about the precise meaning of ‘compulsivity,’ creatingconfusioninthefieldandhamperingcomparisonacross psychiatric disorders. A vague conceptualization makes compulsivity a moving target encompassing a fluctuating variety of behaviors, which is unlikely to improve the new dimension-based psychiatric or psychopathology approach. This article aims to help progress the definition of what constitutes compulsive behavior, cross-diagnostically, by analyzing different definitions in the psychiatric literature. We searched PubMed for articles in human psychiatric research with ‘compulsive behavior’ or ‘compul- sivity’ in the title that focused on the broader concept of compulsivity—returning 28 articles with nine original definitions. Within the definitions, we separated three types of descriptive elements: phenomenological, observational and explanatory. The elements most applicable, cross-diagnostically, resulted in this definition: Compulsive behavior consists of repetitive acts that are characterized by the feeling that one ‘has to’ perform them while one is aware that these acts are not in line with one’s overall goal. Having a more unified definition for compulsive behavior will make its meaning precise and explicit, and therefore more transferable and testable across clinical and non-clinical populations.

Patients who do not respond to one medication sometimes respond to another. Obviously, putting oneself through this process is uncomfortable and often very depressing, but letting oneself off the hook does not feel like an option. A teacher may fear she is not adequately understood when she speaks and never feels she can explain things perfectly enough. In most cases, individuals with OCD feel driven to engage in compulsive behavior and would rather not have to do these time consuming and many times torturous acts. Compulsive overeating is the inability to control one's amount of nutritional intake, resulting in excessive weight gain. This leads to more ritualistic behavior — the vicious cycle of OCD. About the Author: Stacey Kuhl Wochner. Environment An association between childhood trauma and obsessive-compulsive symptoms has been reported in some studies. It is this heightened sense of responsibility, and need to protect loved ones that often drives the person with OCD to repeat the endless cycle of ritualistic behaviours compulsions. These thoughts have to be pervasive and cause problems in health, occupation, socialization, or other parts of life. The goal of clinical trials is to determine if a new test or treatment works and is safe. Mayo Clinic does not endorse companies or products.
