Participants were 57 patients (16 men) and 57 non-patient controls (16 men). https://doi.org/10.1371/journal.pone.0030586.g001. 0000005739 00000 n Heart rate varies in association with spontaneous breathing, and the degree of this variability, measured as RSA, reflects the influence of a vagal brake on the cardiac pacemaker, inhibiting the heart from beating at its intrinsically higher rate [15]. All participants were prescreened as in Experiment 1. Participants were asked to refrain from coffee and other stimulants for at least 2 hours prior to the study. When Reed analyzed the phenomenology of compulsive experiences in OCD, he found that the most common experience reported was an inability to stop—for instance, “I can't move on because I can't convince myself that I've finished what I'm doing” [14] (p.127). After a description of the study to the participants, written informed consent was obtained. Second, complementing the emphasis in CBT on obsessive thoughts in OCD, the perspective advanced here highlights the role of compulsive behavior. A limitation of Experiment 1 is that it considered only one subtype of OCD, namely, washers. �u���2I�0T���J��i ���R,.��� �dQc㴴 0000026373 00000 n %PDF-1.5 %���� The non-patient control participants were recruited to match the age and gender distributions of the patients, but they reported no known mental disorders. A state dominated by parasympathetic influence facilitates social behavior in circumstances that are safe from danger, whereas a state dominated by sympathetic influence facilitates fight-or-flight behavior in circumstances that present imminent danger. The results for actual wash duration and satisfaction clarify the overall picture. IOCDF noted that the feeling is unwanted, overwhelming, and includes intense anxiety which can be very 0000001896 00000 n Yes This finding supports our hypothesis that OCD stems from a reduced ability of security-related behavior to terminate motivation evoked by potential danger. Some studies have found a link between trauma in childhood and OCD. For more information about PLOS Subject Areas, click 0000012496 00000 n Yet the OCD patients reported that they did not feel as satisfied as controls that they had washed enough, suggesting incomplete deactivation of security motivation. Department of Psychology, University of Waterloo, Waterloo, Ontario, Canada, Affiliation 0000012608 00000 n 0000028266 00000 n Interestingly, after the free wash, when all participants had had the opportunity to wash as long as they wished, the difference between groups became smaller and not statistically significant, a result we interpret in the general discussion. This type of cognitive control mechanism is evaluated by tests such as stop-signal inhibition task, go/no-go task, delay-aversion/delay-discounting task, and the 5-choice serial reaction time task, each paradigm tapping different components of the inhibitory control process [54], [56], [62], [63], [64], [65], [66]. A contrasting explanation posits that underlying OCD is a dysfunction of termination—a stopping problem—in which there is failure of the normal process of termination of such security-related thoughts and actions. 0000003490 00000 n 0000003414 00000 n The participant remained seated throughout the experiment and was able to reach the sink at the required times by simply rotating the chair. 0000008451 00000 n The rationale for using RSA stems from polyvagal theory [15], which posits a hierarchy of states of parasympathetic-sympathetic functioning. Affiliation Three of the mixed/no treatment patients also showed symptom reductions, although the researchers caution that they can’t attribute the improvements solely to RDx. e30586. The most important data in this experiment are the RSA values at three times of measurement: after contact with the stimulus (diapers or Styrofoam), after the fixed 30-second wash, and after the subsequent free wash. For each participant, these RSA values were subtracted from baseline RSA, so that higher scores represent higher levels of SMS activation. 0000028826 00000 n Error bars represent 1 SE. 0000034449 00000 n 0000021089 00000 n The funders had no role in study design, data collection and analysis, decision to publish, or preparation of the manuscript. The subsequent 2-min resting period with eyes closed allowed the collection of the final sample of RSA data. Consistent with the results for RSA, there were no significant differences between OCD patients and controls in their feelings of contamination immediately after contact with either dry or wet diapers; both groups rated their feeling of contamination similarly high. OCD Action believes that research plays a vital role in improving the quality of treatment available for people with OCD. No, Is the Subject Area "Hand washing" applicable to this article?

Wrote the paper: ALH EZW MVA LAS HS. 8. They lend support to the security-motivation theory of OCD (Szechtman & Woody, 2004) and have important implications both for research into the biological mechanisms underlying OCD and for the development of new treatment approaches. However, the design of Experiment 1 did not allow us to evaluate the specificity of this stopping deficit. Mail: National Institute of Mental Health Office of Science Policy, Planning, and Communications 6001 Executive Boulevard, Room 6200, MSC 9663 Bethesda, MD 20892-9663 The basic idea would be to develop techniques to teach, or compensate for the weakness of, the security-satiety or stop signal. A consistent finding in brain imaging studies of OCD has been hyperactivity in the orbitofrontal-basal-ganglia circuit [67], [68], [69], suggesting that the OCD symptoms reflect pathology of over-activation in this network. However, there was no significant difference between the OCD patients and the controls in this initial SMS response. To provide an analogy, gastric loading with water rather than food can suppress hunger albeit briefly compared to a nutrient meal, and consequently the motivation to eat will emerge more quickly due to the absence of delayed metabolic inhibitory factors. 0000055973 00000 n 0000011849 00000 n Three levels of stimuli were designed to differ in the level of implied threat of contamination via germs or disease. In contrast, our theoretical model of the “stop” signal is aligned more with the motivational construct of “satiety,” and considers how the course of behavior aroused by a particular motivation comes to its normal end upon attainment of the goal object. Accordingly, possible brain regions of hypoactivity in OCD are neural sites elaborating proprioceptive feedback from the performance of species-typical security-related motor actions. here. The significant effect involving Group was the two-way interaction of Group and Time of Measurement, F(2, 105) = 12.48, p<.001, partial eta-squared = .19, reflecting the general tendency for feelings of contamination to drop after washing significantly less for OCD patients than for control participants. �E�8���5E��)����y�yy�|�|`�#����G�S��. While the growth of the treatment literature for OCD has been impressive since Meyer (1966) first employed ERP with two clients with the condition, there are a number of important limitations in our knowledge of treatment. This does not alter the authors' adherence to all the PLoS ONE policies on sharing data and materials. The present results are consistent with the work of other researchers investigating the idea that OCD stems from a stopping deficit of some kind [37], [38], [39], [40], [41], [42], [43], [44], [45], [46], [47], [48], [49]. OCD symptom severity was confirmed using the Padua-R: All patients had total scores of at least 39, checking subscale scores of at least 20, and a higher score on the checking subscale than on the contamination subscale. 0000010716 00000 n Error bars represent 1 SE. Research into potential OCD biomarkers, such as genes or neurocognitive changes, may provide new scope for optimizing treatment for individual patients on a more personalized basis. No, Is the Subject Area "Diagnostic medicine" applicable to this article? However, rather than conceptualizing OCD in terms of a general underlying cognitive disability to achieve closure, as Reed did, we posited that OCD results from the breakdown of a specific satiety-like mechanism by which engagement in security-related behavior normally shuts down the security motivation system. In the analysis of RSA, there were two statistically significant interactions with Group (OCD patients vs. controls): the three-way interaction of Group, Stimulus, and Time of Measurement, F(4, 210) = 4.48, p<.01, partial eta-squared = .08; and the two-way interaction of Group and Time of Measurement, F(2, 104) = 23.11, p<.001, partial eta-squared = .31. Why do OCD patients tend to have difficulty with only a particular domain of security concerns, but not all? The patients were recruited through the McMaster University Medical Centre (Hamilton Health Sciences) (33 participants) or advertisements in the general community (24 participants). Analyzed the data: ALH EZW MVA LAS HS. 0000004354 00000 n Building on the work of Reed [13], [14], we argued that characterizing OCD as a pathology of stopping better captures the behavioral profile of the disorder [3], [4]. For the purpose of this analysis only, 4 OCD patients were excluded because they were taking a combination of both antidepressant medication and clonazepam. H�\��j�0��~ Our finding that OCD is not characterized by heightened initial sensitivity to potential threat is consistent with findings from other studies (e.g., [24], [25], [26], [27]). 0000058005 00000 n At this time, the second 2-min period of RSA data was collected. Discover a faster, simpler path to publishing in a high-quality journal. Hence, it would make sense to search for brain regions of hypoactivity in OCD, which may reflect dysfunctional negative-feedback, stopping pathways. Hence, it is the actual performance of security-related behavior which signals goal-attainment and generates the negative feedback for terminating security motivation activity. 0000006697 00000 n 0000024235 00000 n 0000004919 00000 n Yes H�\�ݎ�@�{��/g.&]]5$��ѝċ�ɺ� �K�"A������$K����Ri:�춻��\�c�4�8�c׷c�^nc�!��>+J�v��Ϳ͹�g����cן���������0����On�V+��cz��z�V����i/�6���K���į�]9�b�K�C�ı�O1[.ұr��t��ط�ݷ����O=f��Kzx�PM�f����*���. However, individual suffering, functional impairments as well as the direct and indirect costs associated with the disease remain substantial. In summary, OCD can be characterized either as a problem of starting (hypersensitivity to potential threat stimuli) or as a problem of stopping (dysfunction of a satiety-like, negative feedback mechanism). Although compulsive responses are blocked in ERP treatment, recent research indicates that this is not necessary for treatment success; indeed, the opposite possibility, response intensification, may be as effective [72]. 0000003622 00000 n At the end of the study, all participants completed the Padua-R. These results are the first to show that OCD is characterized by a reduced ability of security-related behavior to terminate motivation evoked by potential danger, rather than a heightened initial sensitivity to potential threat. 0000008354 00000 n Participants were 13 patients (4 men) and 15 non-patient controls (5 men). Family FactorsB. For each participant, a data file of interbeat intervals was analyzed to determine the RSA index of vagal tone, using the software CardioEdit and CardioBatch, according to the protocol developed by Porges and colleagues [15], [20]. The results of these experiments show that OCD reflects impairment in the ability of security-related behavior to terminate motivation evoked by potential danger, rather than a heightened initial sensitivity to potential threat. The research reviewed in this article highlights several important dimensions of how to conceptualize and execute treatment for OCD. The Padua-R [19] was used to evaluate OCD symptom severity: All patients had total scores of at least 29, contamination subscale scores of at least 14, and a higher score on the contamination subscale than on the checking subscale. This potential-threat state of autonomic function can be monitored by its characteristic effect on heart-rate variability. All patient participants had a primary diagnosis of OCD, with washing compulsions as the predominant symptom. Next, participants engaged in a prescribed 30-second period of hand washing. There are important implications of the present results for research into the biological mechanisms that underlie OCD. Removal of this brake makes the heart's inter-beat interval less modulated and hence more regular, yielding decreased RSA amplitude (measured in ln msec2), which thus indicates a shift from a safe toward a potential-threat autonomic state. 0000003269 00000 n 0000012382 00000 n As in Experiment 1, the patients were recruited through the McMaster University Medical Centre, (Hamilton Health Sciences) (5 participants) or advertisements in the general community (8 participants).

An initial 2-min, eyes-closed resting period allowed the collection of the baseline RSA. OCD research papers: point 2. Specifically, they were told, “You have 30 seconds to wash, so if you are still washing after 30 seconds, I will ask you to stop.” A subsequent 2-min resting period with eyes closed allowed the collection of the third sample of RSA data. Hence, we suggest, RSA change indexes the immediate component of the stop signal, while subjective satisfaction tracks the delayed or longer-lasting component of the stop mechanism. The experimenter attached ECG electrodes and familiarized participants with operation of the automatic faucet and the procedure for hand washing. Hence, Experiment 2 examines whether similar findings characterize OCD patients with checking compulsions. CiteScore: 2.2 ℹ CiteScore: 2019: 2.2 CiteScore measures the average citations received per peer-reviewed document published in this title. 0000002870 00000 n Accordingly, Szechtman and Woody [3] proposed that OCD is a dysfunction of a biologically primal motivational system that normally helps to protect organisms from potential dangers like disease and attack by predators. 0000003186 00000 n Such a supposition follows from the fact that the structure of security motivation is open-ended in that the external environment does not possess signals of goal-attainment—stimuli indicating that there is no potential danger. Thus, the corrective behavior of washing appears to be just as effective in alleviating SMS activation for OCD checkers as it is for controls. This approach of citation analysis provides an opportunity to retrieve the classic articles on OCD, and describes the trends in OCD research. More research is needed to understand this relationship better. The paradigm used in this experiment was developed previously in a series of studies with non-patient participants [16]. The lowest level of threat was clean Styrofoam beads; the middle level was clean, dry diapers; and the highest level was wetted diapers. These citation classics provide an important insight into the historical developments, like the role of serotonin and caudate in OCD. Click through the PLOS taxonomy to find articles in your field. A second major finding from the present research is that the stopping impairment in OCD appears to be specific to the potential threats involved in the patient's symptoms, helping to explain why the disorder takes the form of relatively distinct symptom clusters. 0000027006 00000 n The corresponding MANCOVA of satisfaction yielded the same two significant effects: for Group×Simulus×Time, F(2, 106) = 3.13, p<.05, partial eta-squared = .06; and for Group×Time, F(1, 106) = 30.01, p<.001, partial eta-squared = .22. Further details of the participants are provided in Table 1. OCD causes the patient’s social life to decrease or otherwise harms it. The neural origin of these stopping pathways is likely in the brainstem, as elaborated elsewhere [3], [4]. Further, RSA change is a relatively pure index of vagal brake removal, unlike heart rate which is also affected by other vagal and sympathetic factors. An unanticipated and intriguing finding from Experiment 1 with OCD washers was that after the free wash, when patients had washed as long as desired, the autonomic index of SMS activity (RSA change) indicated a deactivation of security motivation (consistent with their stopping of hand-washing). Thus, OCD patients repeat these behaviors in an attempt to overcome their weak internal stop signal, which explains why “too much is not enough.” Leahy [71] has integrated this kind of explanation successfully into a CBT-based treatment protocol. Background In obsessive-compulsive disorder (OCD), individuals feel compelled to repeatedly perform security-related behaviors, even though these behaviours seem excessive and unwarranted to them. t���@P�i���;�.��a���0�csL�� ;�$����``[�}�8�V�����ac� �!/�&�^�e���e�D�Y�.

Crucially, such “stop” tests examine if a deficit exists in the normal frontal mechanisms that can interrupt, cancel, or withhold, on-going or intended motor actions [56], [63]. The leftmost panel of Figure 3 shows the relevant adjusted means, which are clearly virtually identical for the checking OCD patients and the non-patient controls. One explanation posits that there is a dysfunction of activation—a starting problem—in which there is pathological intensity of excitation of the system by stimuli suggesting potential danger. To illustrate, the behavioral act of eating brings hunger motivation to an end, but the mechanisms that ultimately arrest further eating and suppress hunger motivation are complex and distinct. The articles in this section were written by mental health professionals and researchers who are experts in OCD and related disorders. Family and Genetics: Twin and family studies have found that people with direct relatives (parent, sibling, or child) who have OCD are at a higher risk for developing OCD themselves. The Brain & Behavior Research Foundation has awarded more than $5 million to obsessive-compulsive disorder (OCD) Research since 1987. According to this account, in OCD, threat concerns would be too readily or too intensely triggered by stimuli [12]. In two experiments, 70 patients with OCD (57 with washing compulsions, 13 with checking compulsions) and 72 controls were exposed to contamination cues—immersing a hand in wet diapers —and later allowed to wash their hands, first limited to 30 s and then for as long as desired. ComorbidityII. 0000009519 00000 n Participants were then instructed to remove their hand from the bin, hold it motionless in their lap (to avoid movement artifacts), and focus attention on it with eyes closed.

PLOS ONE promises fair, rigorous peer review, For each of the two diaper conditions, seven of the diapers were piled in a hospital wastebin labeled Pediatrics; in the Styrofoam-beads condition, a similar but unlabeled container was used. Looking first at the after-contact time-of-measurement for each of the stimulus conditions, it was evident that for both the OCD patients and the control participants, contact with diapers elicited much greater activation than contact with Styrofoam. Moreover, we propose that a deficiency of the delayed components makes OCD patients particularly susceptible to re-activation by potential threat. 2016-2019) to peer-reviewed documents (articles, reviews, conference papers, data papers and book chapters) published in the same four calendar years, divided by … Importantly, this stop mechanism is distinctly different from the type of stop mechanisms proposed by several other investigators as impaired in OCD [51], [52], [53], [54], [55] and impulsivity [54], [56], [57], [58], [59], [60], [61]. This finding is inconsistent with the hypothesis, proposed by some theorists [12], that OCD stems from heightened sensitivity to activation by potential threats. 0000077054 00000 n Participants washed their hands at a sink fitted with an automatic, motion-activated faucet that was preset to deliver a consistent flow of warm water (at about 25°C).
