It is widely agreed that obsessive-compulsive disorder involves irrationality. But where in the complex of states and processes that constitutes OCD should this irrationality be located? A pervasive assumption in both the psychiatric and philosophical literature is that the seat of irrationality is located in the obsessive thoughts characteristic of OCD. Building on a puzzle about insight into OCD (Taylor 2022), we challenge this pervasive assumption, and argue instead that the irrationality of OCD is located in the emotions (...) that are characteristic of OCD, such as anxiety or fear. In particular, we propose to understand the irrationality of OCD as a matter of harboring recalcitrant emotions. We argue that this account not only solves the puzzle about insight, but also makes better sense of how OCD sufferers experience and describe their condition and helps explain some otherwise puzzling features of compulsive behavior.

An influential model holds that obsessive–compulsive disorder is caused by distinctive personality traits and belief biases. But a substantial number of sufferers do not manifest these traits. I propose a predictive coding account of the disorder, which explains both the symptoms and the cognitive traits. On this account, OCD centrally involves heightened and dysfunctionally focused attention to normally unattended sensory and motor representations. As these representations have contents that predict catastrophic outcomes, patients are disposed to engage in (...) behaviors and mental rituals designed to forestall these outcomes or to produce more precise information. The same representations also cause the cognitive traits characteristic of sufferers. (shrink)

Obsessive-compulsive disorder (OCD) is considered to be one of the more common serious mental disorders, with a prevalence rate of about 1% (Heyman et al. 2006). It is characterized by obsessions, or compulsions, or both. According to the DSM-IV (American Psychiatric Association 1994), obsessions are “recurrent and persistent thoughts, impulses, or images that are experienced at some time during the disturbance, as intrusive and inappropriate and that cause marked anxiety or distress.” Compulsions, on the other hand, are repetitive (...) behaviors (e.g., hand washing, ordering, checking) or “mental acts that the person feels driven to perform in response to an obsession, or according to rules that must be applied ..

Obsessive-Compulsive Disorder and Uncertainty examines the intrapsychic features of the self as it presents within OCD compulsive doubting. Moshe Marcus and Steven Tuber suggest a phenomenological framework through which to consider the interplay between the cognitive as well as affective components required to make judgments.

In this article we examine obsessive compulsive disorder (OCD). We examine and reject two existing models of this disorder: the Dysfunctional Belief Model and the Inference‐Based Approach. Instead, we propose that the main distinctive characteristic of OCD is a hyperactive sub‐personal signal of being in error, experienced by the individual as uncertainty about his or her intentional actions (including mental actions). This signalling interacts with the anxiety sensitivities of the individual to trigger conscious checking processes, including speculations (...) about possible harms. We examine the implications of this model for the individual's capacity to control his or her thoughts. (shrink)

The history of mental illnesses is as old as human history. Mental disorders are affected by changing social and cultural factors during the historical process, and have been conceptually restructured and their definitions and classifications have been changed. The evolution of obssessive-compulsive disorders with roots as old as human history into modern concepts took place in the 19th century. The first scientific views on the spiritual origin of OCD belong to S. Freud. Freud observed that mental causes in OCD (...) are different from other mental disorders, and he examined obsession as a separate and specific disorder. Over time, it has been understood that OCD is a very common disorder. The American Psychiatric Association (APA) has classified OCD under an independent title in the latest version of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) by removing it from the category of anxiety disorders. OCD is a mental disorder caused by mental actions such as obsessive thoughts (obsessions) and / or repetitive and compulsive behaviors (compulsion). The patient is often aware that such thoughts and behaviors are irrational and absurd. For this reason, he tries to get away obsessive thoughts that he finds contrary to his beliefs, opinions, moral values and logic from his mind. However, as he tries, obsessive thoughts become more and more frequent and create a great anxiety in the person. This time, the patient resorts to compulsions to alleviate the anxiety he feels or to get rid of it completely. As his compulsions repeat, his anxiety increases and he goes into a vicious circle. There are many symptom subgroups of OCD that seriously worsen the quality of life of the individual. One of these, and even the most overwhelming, is religious obsessions. It has been thought that there has been a relationship between religion and OCD for a long time in the psychology literature, and some remarkable studies have been conducted to clarify this relationship. Although there are many research findings showing that religion is an indispensable element in the protection of the mental health integrity of the individual, some forms of religious understanding and some experiences gained as a result of religious experiences may affect the concerns about OCD. This stage of religiosity is closely related to some sub-symptom groups of OCD. The explanations of the founder of the psychoanalytic method, Freud psychoanalytic method, and his followers made a great contribution to the understanding of OCD. However, since the psychoanalytic method exhibits a theoretically reductionist approach to religion, it is possible that the individual's devotion to religion is initially evaluated as a pathology or at least an important obstacle to insight. Today, cognitive behavioral psychotherapies are considered the most effective psychological treatment method for OCD, but their success rates in the treatment of religious OCD are low. Since religious OCD concerns often involve spiritual issues rather than concrete repeatable situations, behavioral methods can be quite difficult to apply in the treatment of religious OCD. Therefore, traditional psychotherapy approaches, even if they are not openly against religions, are insufficient to relieve the suffering in the lives of individuals with religious obsessions, as they generally neglect the religious dimension. Due to the vacuum that arises from restricting spiritual treatments to secular approaches, religious patients are threatened by the illegal practices of people who abuse religious feelings. Clinically, religious obsessions are more worrying and overwhelming. Therefore, their treatment is more difficult than others. Selective approaches that use different scientific disciplines together in the treatment of OCD and can stretch around religious beliefs and values can create more effective treatment models. Thus, the success rate in the treatment of religious OCD can be carried to higher levels thanks to the appropriate cooperation of the disciplines of medicine, psychology and theology. There is a rich religious cultural heritage that can support this collaboration in terms of theological disciplines. As an example, Abū Zayd al-Balkhī (d. 322/934), in his Maṣāliḥ al-abdān wa-l-anfus, probably made a clear distinction between neuroses and psychosis and classified neurotic disorders for the first time about ten centuries before Freud. In this study, the importance of approaching to religious obsessions as both a psychological disorder and a theological problem is emphasized. For this reason, cooperation of psychiatric and psychological approaches with spiritual counseling and guidance is recommended in the treatment of religious OCD. The difficulty in distinguishing whether the symptoms seen in a religious person are normal, natural religious thoughts and behaviors of religious life or abnormal appearances in the religious guise necessitates this interdisciplinary cooperation.

People suffering from Obsessive-Compulsive Disorder (OCD) do things they do not want to do, and/or they think things they do not want to think. In about 10 percent of OCD patients, none of the available treatment options is effective. A small group of these patients is currently being treated with deep brain stimulation (DBS). Deep brain stimulation involves the implantation of electrodes in the brain. These electrodes give a continuous electrical pulse to the brain area in which they (...) are implanted. It turns out that patients may experience profound changes as a result of DBS treatment. It is not just the symptoms that change; patients rather seem to experience a different way of being in the world. These global effects are insufficiently captured by traditional psychiatric scales, which mainly consist of behavioural measures of the severity of the symptoms. In this article we aim to capture the changes in the patients’ phenomenology and make sense of the broad range of changes they report. For that we introduce an enactive, affordance-based model that fleshes out the dynamic interactions between person and world in four aspects. The first aspect is the patients’ experience of the world. We propose to specify the patients’ world in terms of a field of affordances, with the three dimensions of broadness of scope (‘width’ of the field), temporal horizon (‘depth’), and relevance of the perceived affordances (‘height’). The second aspect is the person-side of the interaction, that is, the patients’ self-experience, notably their moods and feelings. Thirdly, we point to the different characteristics of the way in which patients relate to the world. And lastly, the existential stance refers to the stance that patients take towards the changes they experience: the second-order evaluative relation to their interactions and themselves. With our model we intend to specify the notion of being in the world in order to do justice to the phenomenological effects of DBS treatment. (shrink)

Deep Brain Stimulation (DBS) is a relatively new, experimental treatment for patients suffering from treatment-refractory Obsessive Compulsive Disorder (OCD). The effects of treatment are typically assessed with psychopathological scales that measure the amount of symptoms. However, clinical experience indicates that the effects of DBS are not limited to symptoms only: patients for instance report changes in perception, feeling stronger and more confident, and doing things unreflectively. Our aim is to get a better overview of the whole variety of (...) changes that OCD patients experience during DBS treatment. For that purpose we conducted in-depth, semi-structured interviews with 18 OCD patients. In this paper, we present the results from this qualitative study.We list the changes grouped in four domains: with regard to (a) person, (b) (social) world, (c)characteristics of person-world interactions, and (d) existential stance. We subsequently provide an interpretation of these results. In particular, we suggest that many of these changes can be seen as different expressions of the same process; namely that the experience of anxiety and tension gives way to an increased basic trust and increased reliance on one’s abilities. We then discuss the clinical implications of our findings, especially with regard to properly informing patients of what they can expect from treatment, the usefulness of including CBT in treatment, and the limitations of current measures of treatment success. We end by making several concrete suggestions for further research. (shrink)

Hoarding disorder is a psychiatric condition characterized by difficulty discarding items and accumulation of clutter. Although studies have established the negative impact of HD and compulsive hoarding behavior, fewer have examined the impact on quality of life of hoarding behavior independent of obsessive–compulsive disorder. Moreover, specific aspects of QoL such as success in work/academics or satisfaction with interpersonal relationships have not been well-investigated. In this study, we examined, in a sample of 2100 adult participants obtained from (...) Amazon Mechanical Turk, the relationships between hoarding, OCD, and depression symptomatology and four QoL domains derived from a factor analysis of the Quality of Life Inventory. We performed linear regressions to examine associations between psychiatric symptomatology and QoL domains and then conducted mediation analyses to investigate the role of depressive symptomatology in the identified relationships. We found that while hoarding and obsessive–compulsive symptoms were both negatively associated with QoL, they were associated with different domains [hoarding was significantly associated, and was less strongly associated with success or enrichment. Mediation analyses confirmed the role of depression as a complete mediator of hoarding’s effect on total, environment, and family QoL, and as a partial mediator of hoarding’s effect on success and enrichment QoL. Further examination of the relationship between hoarding symptoms and QoL in those with mild, moderate, and severe depression indicated that in those with more severe depression, hoarding was associated with improved QoL, indicating a possible buffering or compensatory effect. The findings suggest a differential impact of hoarding and obsessive–compulsive symptoms on QoL and emphasize the importance of considering co-morbid depressive symptoms in designing more targeted interventions. Future studies should continue to investigate these complex relationships, given the high co-morbidity of hoarding and depression. (shrink)

The dominant philosophical conceptions of obsessive-compulsive behavior present its subject as having a deficiency, usually characterized as volitional, due to which she lacks control and choice in acting. Compulsions (mental or physical) tend to be treated in isolation from the obsessive thoughts that give rise to them. I offer a different picture of compulsive action, one that is, I believe, more faithful to clinical reality. The clue to (most) obsessive-compulsive behavior seems to be the way obsessive thoughts, (...) which are grounded in an irrational cognitive style in matters of risk, danger, and responsibility, motivate compulsions through bizarre means–end reasoning. I show that the patient with obsessive-compulsive disorder (OCD) is not weak and passive with regard to the compulsive act; rather, the act is voluntary and regarded by the patient as an instrument of control. I also defend the idea that OCD-related cognitions are either beliefs or mental states with relevantly similar functional roles. (shrink)

Obsessive-compulsive disorder (OCD) is a deeply enigmatic psychiatric condition associated with immense suffering worldwide. Efficacious therapies for OCD, like exposure and response prevention (ERP) are sometimes poorly tolerated by patients. As many as 25 percent of patients refuse to initiate ERP mainly because they are too anxious to follow exposure procedures. Accordingly, we proposed a simple and tolerable (immersive yet indirect) low-cost technique for treating OCD that we call “multisensory stimulation therapy.” This method involves contaminating a rubber hand (...) during the so-called “rubber hand illusion” (RHI) in which tactile sensations may be perceived as arising from a fake hand. Notably, Jalal and Ramachandran (2015), showed that such fake hand contamination during the RHI provokes powerful disgust reactions in healthy volunteers. In the current study, we explored the therapeutic potential of this novel approach. OCD patients (n = 29) watched as their hidden real hand was being stroked together with a visible fake hand; either synchronously (inducing the RHI) (i.e., the experimental condition; n = 16) or asynchronously (i.e., the control condition; n = 13). After 5 minutes of tactile stimulation, the rubber hand was contaminated with fake feces, simulating conventional exposure therapy. Intriguingly, results suggested sensory assimilation of contamination sensations into the body image via the RHI: patients undergoing synchronous stimulation did not report greater contamination sensations when the fake hand was initially contaminated relative to asynchronous stroking. But contrary to expectations, they did so after the rubber hand had been contaminated for 5 minutes; as assessed via disgust facial expressions (a secondary outcome) and in vivo exposure (upon discontinuing the illusion). Further to our surprise, synchronous and asynchronous stroking induced an equally vivid and fast emerging illusion, which helps explain why both conditions initially (5 minutes after initiating tactile stimulation) provoked contamination reactions of equal magnitude. This study is the first to suggest heightened malleability of body image in OCD. Importantly, it may pave the way for a tolerable technique for the treatment of OCD—highly suitable for poorly resourced and emergency settings, including low-income and developing countries with minimal access to high-tech solutions like virtual reality.

This article discusses a puzzle arising from the phenomenon of insight in obsessive–compulsive disorder. “Insight” refers to an awareness or understanding of obsessive thoughts as false or irrational. I argue that a natural and plausible way of characterizing insight in OCD conflicts with several different possible explanations of the epistemic attitude underlying insight‐directed obsessive thought. After laying out the puzzle for five proposed explanations of obsessive thought and then discussing several possible ways that the puzzle might be avoided, (...) I close the article by arguing that we can avoid the puzzle by adopting a new positive view of insight‐directed obsessive thought. (shrink)

How does doubt come about? What are the mechanisms responsible for our inclinations to reassess propositions and collect further evidence to support or reject them? In this paper, I approach this question by focusing on what might be considered a distorting mirror of unreasonable doubt, namely the pathological doubt of patients with obsessive–compulsive disorder (OCD). Individuals with OCD exhibit a form of persistent doubting, indecisiveness, and over-cautiousness at pathological levels (Rasmussen and Eisen in Psychiatr Clin 15(4):743–758, 1992; Reed (...) in Obsessional experience and compulsive behaviour: a cognitive-structural approach, Academic Press, Cambridge, 1985; Tolin et al. in Cogn Ther Res 27(6):657–669, 2003). I argue that the failure in OCD is of an affective nature, involving both excessive epistemic anxiety and hyperactive feelings of uncertainty. I further argue that our adaptive disposition to inquire about the right matters—that is, about propositions which are both epistemically risky and imply harmful possibilities—might depend on these affective mechanisms.

Progress in psychiatry depends on accurate definitions of disorders. As long as there are no known biologic markers available that are highly specific for a particular psychiatric disorder, clinical practice as well as scientific research is forced to appeal to clinical symptoms. Currently, the nosology of obsessive-compulsive disorder is being reconsidered in view of the publication of DSM-V. Since our diagnostic entities are often simplifications of the complicated clinical profile of patients, definitions of psychiatric disorders are imprecise (...) and always indeterminate. This urges researchers and clinicians to constantly think and rethink well-established definitions that in psychiatry are at risk of being fossilised. In this paper, we offer an alternative view to the current definition of obsessive-compulsive disorder from a phenomenological perspective.TranslationThis article is translated from Dutch, originally published in [Handbook Obsessive-compulsive disorders, Damiaan Denys, Femke de Geus (Eds.), (2007).

The United States Food and Drug Administration's recent approval of the commercial use of Deep Brain Stimulation (DBS) as a treatment for Obsessive Compulsive Disorder (OCD) will be discussed within the context of the existing USA regulatory framework. The purpose will be to illustrate the current lack of regulation and oversight of the DBS market, which has resulted in the violation of basic ethical norms. The discussion will focus on: 1) the lack of available evidence on procedural safety (...) and efficacy, 2) the numerous conflicts of interest held by research investigators, and 3) the ambiguity of both aforementioned categories due to an inherent lack of transparency in the research. It is argued that in order to address these issues, ethical analyses of DBS for psychiatric disorders must include the role of the industry forces that have become the primary impetus for this research. As such, DBS for OCD serves as an important case example in studies of neurotechnology and innovative surgery. (shrink)

According to the traditional Western concept of freedom, the ability to exercise free will depends on the availability of options and the possibility to consciously decide which one to choose. Since neuroscientific research increasingly shows the limits of what we in fact consciously control, it seems that our belief in free will and hence in personal autonomy is in trouble. -/- A closer look at the phenomenology of Obsessive-Compulsive Disorder (OCD) gives us reason to doubt the traditional concept (...) of freedom in terms of conscious control. Patients suffering from OCD experience themselves as unfree. The question is whether their lack of freedom is due to a lack of will power. Do they have too little conscious control over their thoughts and actions? Or could it be the opposite: are they exerting too much conscious control over their thoughts and actions? -/- In this chapter, we will argue that OCD patients testify to the general condition that exercising an increased conscious control over actions can in fact diminish the sense of agency rather than increase the experience of freedom. The experiences of these patients show that the traditional conception of freedom in terms of ‘free will’ has major shortcomings. There is an alternative, however, to be found in the work of Hannah Arendt. She advocates a conception of freedom as freedom in action. Combined with phenomenological insights on action, Arendt’s account of freedom helps us to get a more adequate understanding of the role of deliberation in the experience of freedom. We argue that the experience of freedom depends on the right balance between deliberate control and unreflective actions. (shrink)

Emotions might contribute to our being rational cognitive agents. Anxiety – and more specifically epistemic anxiety – provides an especially interesting case study into the role of emotion for adaptive cognition. In this paper, I aim at clarifying the epistemic contribution of anxiety, and the role that ill-calibrated anxiety might play in maladaptive epistemic activities which can be observed in psychopathology. In particular, I argue that this emotion contributes to our ability to adapt our cognitive efforts to how we represent (...) the practical factors relevant to the task at hand, by sig- naling the need for increased cognitive processing and evidence gathering in high- stakes situations. I hypothesize that dysfunctional or ill-calibrated epistemic anxiety might play an important role in the motivation driving persons with obsessive- compulsive disorder (OCD) to invest high amounts of cognitive resources into the resolution of apparently simple and innocuous questions. As I argue, OCD might be conceived as a case in which epistemic anxiety is inappropriately elicited, represent- ing these as high-stakes questions, and inadequately signaling a need for cognition. In this paper, I thus make use of the concept of (epistemic) anxiety as developed in the philosophy of emotion and in epistemology, to propose an account of the role of anxiety in the pathological doubt that is central to obsessive-compulsive disorder.

Obsessive compulsive disorder is a debilitating psychiatric condition where people become obsessed by remotely possible harm, error, bad luck, and compulsively repeat mental or behavioural rituals to neutralize these possibilities. This tendency to draw inferences on the basis of remote rather than more likely possibilities is termed 'inferential confusion' and can lead to immersion in possible worlds accompanied by feelings of dissociation between: knowing and doing, imagination and reality, and authentic and inauthentic self. These dissociation experiences in OCD (...) may inform us on the relational 'possibilistic' nature of consciousness. In a relational model of consciousness, the boundaries of consciousness are located between the person and the world, and shift according to the 'aboutness' of self-world interaction. A key element of 'aboutness' is projecting into the future to what is 'about to be', so sense of reality is constructed through a consensus about what could be, operationalized as a personal possibility distribution. Experiences such as derealization and depersonalization occur in OCD when there is a clash between personally possible worlds and the person ends up living in simultaneously a possible and an impossible world. Recognizing this confusion may be a key to alleviating dissociative symptoms. (shrink)

In this paper, I will provide a phenomenological analysis of somatic obsessions at times present in obsessive–compulsive disorder. I will compare two different types of bodily obsessions, which have a different neurological-physiological underpinning: anguishing awareness of one’s own heartbeat and of one’s own breathing. In addition, I will contrast these two with how one experiences one’s own liver. I will use the concepts "tactility obsessions” and "motility obsessions”, which I have coined for the purpose of this comparison. In (...) other words, these are obsessions concerning the felt sense of one’s autonomous organs and obsessions concerning one’s ability to voluntarily move. Ultimately, I claim that the core lived experience in somatic obsessive–compulsive disorder should not only be understood as having to do with intruding and "distorted thoughts” concerning bodily processes, but could also be understood as having to do with a felt sense of our organs interrupting and intruding our daily lives.

The current work takes a phenomenological approach to investigating the role of guilt in a sample of persons diagnosed with Obsessive-Compulsive Disorder . The role of guilt in OCD has been frequently noted in the literature, although infrequently studied as a factor in its own right. Typically, those studying OCD have found positive correlations between questionnaire measures of guilt and self-reported symptoms of OCD. Those working with sufferers have also found that OC clients in therapy report feelings of (...) guilt with respect to their symptoms. The present work investigates, in a qualitative way, the meaning of guilt for those with OCD. The presumed role of guilt is examined descriptively, with an eye to developing a more complete understanding of the relationship between feelings of guilt and OC symptoms in a sample of sufferers. Nine participants were recruited, and were interviewed using an unstructured approach. In terms of analysis, emphasis was placed on understanding the experience of guilt and OC symptoms as both were lived by sufferers, with a focus on the personal significance of guilt for study participants. Fifteen descriptive guilt/OCD themes were derived from interviews across the nine participants. Themes revealed a variety of connections that sufferers made between feelings of guilt and symptoms of OCD. A common description of the experience was also derived. The results suggest that the role of guilt in OCD is highly interpersonal in nature, and that feelings of guilt may precede, motivate, as well as be a consequence of, OC symptoms. The role of guilt for any given sufferer may also be highly idiosyncratic. (shrink)

Background:The belief that we can control our thoughts is not inevitably adaptive, particularly when it fuels mental control activities that have ironic unintended consequences. The conviction that the mind can and should be controlled can prompt people to suppress unwanted thoughts, and so can set the stage for the intrusive return of those very thoughts. An important question is whether or not these beliefs about the control of thoughts can be reduced experimentally. One possibility is that behavioral experiments aimed at (...) revealing the ironic return of suppressed thoughts might create a lesson that could reduce unrealistic beliefs about the control of thoughts. Aims: The present research assessed the influence of the thought suppression demonstration on beliefs about the control of thoughts in a non-clinical sample, and among individuals with obsessive-compulsive disorder (OCD). Method: In Study 1, we assessed the effect of the thought suppression demonstration on beliefs about the control of thoughts among low and high obsessive individuals in the non-clinical population (N= 62). In Study 2, we conducted a similar study with individuals with OCD (N= 29). Results: Results suggest that high obsessive individuals in the non-clinical population are able to learn the futility of suppression through.. (shrink)

Anorexia nervosa and obsessive–compulsive disorder are commonly reported to co-occur and present with overlapping symptomatology. Executive functioning difficulties have been implicated in both mental health conditions. However, studies directly comparing these functions in AN and OCD are extremely limited.

We outline the similarities and differences in behavioral and neuroimaging findings between AN and OCD, focusing on (...) set shifting, working memory, response inhibition, and response monitoring. This review aims to facilitate understanding of transdiagnostic correlates of executive functioning and highlights important considerations for future research. We also discuss the importance of examining both behavioral and neural markers when studying transdiagnostic correlates of executive functions. (shrink)

Why do thoughts involving harm and damage trigger guilt in certain individuals and not in others? The significance of this question comes into view when considering the medical and psychological literature on patients with obsessive-compulsive disorder (OCD). Patients with OCD feel guilt in response to having certain recurring, negative thoughts whose content evoke scenarios of harm and damage. This, however—at least in most readings of what those thoughts consist of—is puzzling. The transition from having a thought about being (...) the source of harm popping up in one’s mind to feeling guilty is not straightforward, and it calls for explanation. Indeed, OCD appears to challenge a traditional picture of what guilt is all about... (shrink)

Numerous sex differences in obsessive-compulsive disorder (OCD) instantiations are likely universal, as the associated evolutionary threats and concerns onto which they map were differentially important to the two sexes. Hence, although some ritualized behaviors or thoughts are indeed culture-specific, others are both culturally and temporally invariant as they are rooted in universal Darwinian etiologies (e.g., the sex differences in OCD symptomatology posited here).

Objective: This study aimed to explore the relationship among cognitive fusion, experiential avoidance, and obsessive–compulsive symptoms in patients with obsessive–compulsive disorder.Methods: A total of 118 outpatient and inpatient patients with OCD and 109 healthy participants, gender- and age-matched, were selected using cognitive fusion questionnaire, acceptance and action questionnaire−2nd edition, Yale–Brown scale for obsessive–compulsive symptoms, Hamilton anxiety scale, and Hamilton depression scale for questionnaire testing and data analysis.Results: The levels of cognitive fusion and experiential avoidance in the (...) OCD group were significantly higher than those in the healthy control group. Regression analysis results showed that, in predicting the total score of obsessive–compulsive symptoms, AAQ-II and CFQ entered the equation, which explained 17.1% variance. In predicting anxiety, only AAQ-II entered the equation, which explained 13% variance. In the prediction of depression, AAQ-II entered the equation, which explained 17.7% variance.Conclusion: Cognitive fusion and experiential avoidance may be important factors for the maintenance of OCD, and experiential avoidance can positively predict the anxiety and depression of OCD patients.

A central methodological innovation in cognitive science has been the development of connectionist or neural network models of psychological phenomena. These models may also comprise a theoretically integrative and methodologically rigorous approach to psychiatric phenomena. In this paper we employ connectionist theory to conceptualize obsessive-compulsive disorder . We discuss salient phenomenological and neurobiological findings of the illness, and then reformulate these using neural network models. Several features and mechanisms of OCD may be explicated in terms of disordered networks. (...) Neural network modeling appears to constitute a novel and potentially fertile approach to psychiatric disorders such as OCD. (shrink)

Deep brain stimulation — a novel surgical procedure — is emerging as a treatment of last resort for people diagnosed with neuropsychiatric disorders such as severe obsessive-compulsive disorder. The US Food and Drug Administration granted a so-called humanitarian device exemption to allow patients to access this intervention, thereby removing the requirement for a clinical trial of the appropriate size and statistical power. Bypassing the rigors of such trials puts patients at risk, limits opportunities for scientific discovery, and gives (...) device manufacturers unique marketing opportunities. We argue that Congress and federal regulators should revisit the humanitarian device exemption to ensure that it is not used to sidestep careful research that can offer valuable data with appropriate patient safeguards.

Focal brain metabolic effects detected by proton magnetic resonance spectroscopy (MRS) in obsessive-compulsive disorder (OCD) represent prospective indices of clinical status and guides to treatment design. Sampling bilateral pregenual anterior cingulate cortex (pACC), anterior middle cingulate cortex (aMCC), and thalamus in 40 adult patients and 16 healthy controls, we examined relationships of the neurometabolites glutamate+glutamine (Glx), creatine+phosphocreatine (Cr), and choline-compounds (Cho) with OCD diagnosis and multiple symptom types. The latter included OC core symptoms (Yale-Brown Obsessive-Compulsive Scale - (...) YBOCS), depressive symptoms (Montgomery-Åsberg Depression Rating Scale - MADRS), and general functioning (Global Assessment Scale - GAS). pACC Glx was 9.7% higher in patients than controls. Within patients, Cr and Cho correlated negatively with YBOCS and MADRS, while Cr correlated positively with the GAS. In aMCC, Cr and Cho correlated negatively with MADRS, while Cr in thalamus correlated positively with GAS. These findings present moderate support for glutamatergic and cingulocentric perspectives on OCD. Based on our prior metabolic model of OCD, we offer one possible interpretation of these group and correlational effects as consequences of a corticothalamic state of elevated glutamatergic receptor activity alongside below-normal glutamatergic transporter activity.

Fear to contamination is an easy-to-provoke, intense, hard-to-control, and extraordinarily persistent fear. A worsening of preexisting psychiatric disorders was observed during the COVID-19 outbreak, and several studies suggest that those with obsessive–compulsive disorder may be more affected than any other group of people. In the face of worsening OCD symptoms, there is a need for mental health professionals to provide the support needed not only to treat patients who still report symptoms, but also to improve relapse prevention. In (...) this line, it is recommended to improve alternative strategies such as online consultations and digital psychiatry. The aim of this study is to develop augmented reality stimuli that are clinically relevant for patients with cleaning OCD and assess their efficiency to obtain emotionally significant responses. Four AR stimuli were developed: a plastic bag full of garbage, a piece of bread with mold, a dirty sports shoe, and a piece of rotten meat. All stimuli were shown to a clinical group and a control group. Relevant results were the design of the AR stimuli. These stimuli were validated with the statistical difference in perceived anxiety in the meat stimuli between the clinical and control groups. Nevertheless, when looking at effect sizes, all stimuli present effect sizes from small to large, with both shoe and bread between small and medium effect sizes. These results are a valuable support for the clinical use of these AR stimuli in the treatment of cleaning OCD. (shrink)

Psychologists and cultural historians typically have argued that early modern theologians such as Martin Luther, John Bunyan, and Ignatius Loyola exhibited behavior that the Diagnostic and Statistical Manual of Mental Disorders (DSM IV) classifies as a subtype of obsessive-compulsive disorder termed “religious scrupulosity.” This essay argues that, although early modern theologians do manifest scrupulosity, such religiosity was a culturally acceptable, even recommended component of spiritual progress, a necessary means of receiving an unmerited bestowal of God’s grace. The larger (...) aim of the essay is to point out some of the limitations of current DSM criteria when attempting retrospectively to diagnose historical figures with mental pathology. (shrink)
