RESUMO

OBJECTIVES: The feared possible self refers to an imagined version of self that one is afraid of being or becoming. Previous evidence has shown that dysfunctional reasoning (i.e., inferential confusion) is associated with obsessive-compulsive disorder (OCD) symptoms, which is partially mediated by a feared self. However, the evidence is reliant on non-clinical samples and a general measure of the feared self. METHODS: Using a cross-sectional design, the current study attempted to replicate and extend this literature in a sample clinically diagnosed with OCD (n = 350) to assess the pathway from inferential confusion to OCD symptoms when feared self is accounted for as a mediator, particularly the individual dimensions of feared self (i.e., corrupted, culpable, and malformed feared selves). Participants completed a structured clinical interview for DSM-5, as well as measures of inferential confusion (Dysfunctional Reasoning Processes Task), obsessive beliefs, feared self, OCD symptoms, and psychological distress. RESULTS: Inferential confusion directly, and indirectly through the feared corrupted self, affected OCD symptoms, even after adjusting for obsessive beliefs, psychological distress, and comorbidity. However, the feared culpable and malformed selves did not play a role in this pathway. CONCLUSIONS: The study underscores that the feared corrupted self links inferential confusion to OCD symptoms, translating to the need to consider both dysfunctional reasoning processes and this specific feared self in clinical settings when treating OCD. Furthermore, the study provides more support for the inference-based approach (IBA) to OCD.

RESUMO

Research suggests that individuals with obsessive-compulsive and related disorders (OCRDs) with lower insight show a poorer response to cognitive behavioral therapy and might benefit from alternative treatments. However, there are inconsistencies in the literature regarding the definition and measurement of insight. This study endeavored to evaluate the psychometric properties of the Cognitive Obsessional Insight Scale (COGINS), a novel self-report measure of cognitive insight in OCRDs. The sample comprised 166 participants with a diagnosis of obsessive-compulsive disorder or body dysmorphic disorder enrolled in clinical trials. Participants completed the COGINS and a questionnaire battery at baseline and posttreatment. The COGINS demonstrated good internal consistency, test-rest reliability, convergent validity with other OCRD-specific measures of insight, positive associations with OCRD symptomatology, and had a moderating effect on treatment response. The COGINS is a valid and reliable practical tool to measure cognitive insight in OCRDs and might help toward clarifying the role of cognitive insight in this population.

RESUMO

OBJECTIVES: There is a significant relationship between a general feared self and contact contamination concerns in obsessive-compulsive disorder (OCD), especially when the influence of mental contamination is considered a part of this relationship. However, these associations have not been explored in a clinical OCD sample when using each dimension of the multidimensional conceptualization of the feared self as the predictor (i.e., the corrupted, culpable, and malformed feared selves). METHODS: We tested these associations using a cross-sectional design. Specifically, a sample of patients diagnosed with OCD (N = 417) completed a series of self-report measures of OCD symptoms and its related constructs. We also explored these associations with unacceptable thoughts as the outcome, rather than contamination concerns, due to unacceptable thoughts having evidenced strong associations with the feared self and mental contamination. RESULTS: After controlling for relevant cognitive (i.e., obsessive beliefs) and affective (i.e., depressive symptoms) constructs and comorbidity, the corrupted feared self was found to have a direct link, along with an indirect link through mental contamination, with symptoms of contact contamination and unacceptable thoughts. CONCLUSIONS: The fear of being corrupted may be associated with feelings of contamination in the absence of direct contact with a contaminant, which may then predict OCD symptoms of repugnant obsessional thoughts and contact contamination concerns. The corrupted feared self and mental contamination should therefore be targeted in treatments for repugnant obsessions and contamination-related OCD.

RESUMO

The Diagnostic and Statistical Manual 5th ed. defines obsessions in obsessive-compulsive disorder (OCD) as frequent, persistent, intrusive, unwanted thoughts that provoke anxiety and distress and lead to attempts to neutralize them with either thoughts or actions. However, no systematic review has yet evaluated characteristics that are specific to obsessions occurring in OCD. The aim of the current systematic review and meta-analysis was to investigate the specific features of obsessions occurring in OCD by comparing them to both obsessionally and non-obsessionally-themed intrusions in non-clinical and other clinical populations. Based on a registered protocol, 832 records were found, of which 15 were included in the systematic review and meta-analysis, with a total of 1891 participants. Obsessionally-themed intrusions that occur among those with OCD caused more distress, guilt, negative emotion and interference as compared to similarly-themed intrusions that occur within the general population. The distinction between obsessionally-themed intrusions among those with OCD as compared to those occurring in anxiety and depressive disorder primarily revolves around a higher level of persistence, pervasiveness and distress associated with their occurrence. Further, unacceptability, uncontrollability, ego-dystonicity, alienness, guilt, the form of the intrusion, association with the self and lack of any basis in reality also differentiates between obsessions and intrusions occurring in other disorders. Obsessions share many characteristics with thoughts occurring in other disorders and can be distinguished using a combination of characteristics specific to individual disorders.

RESUMO

Specific concerns have been raised for those suffering from obsessive-compulsive disorder (OCD) during the COVID-19 pandemic, particularly those suffering from contamination fear. Investigation in non-clinical and OCD samples have reported an increase in contamination symptoms in association with the severity of the COVID-19 pandemic. In particular, stress related to COVID-19 has been found to be a major predictor of an increase in contamination symptoms. It has also been suggested that these effects may be accounted for by feared-self perceptions, that renders certain individuals more vulnerable to COVID-related stress and its effect on contamination-related symptomatology. We hypothesized that feared self-perceptions would predict COVID-19-related stress and that both feared self-perceptions and COVID-19-related stress would predict contamination symptoms while controlling for age, education and sex. To test this hypothesis, 1137 community participants completed online questionnaires. Path analysis confirmed our hypotheses highlighting the importance of feared self-perceptions during the COVID-19 pandemic in its effect on stress and ensuing symptomatology. Further, women scored higher on questionnaires, but the relationship between feared self-perceptions, COVID-19-related stress and contamination symptoms remained similar. Implications for theory and research are discussed.

RESUMO

BACKGROUND AND OBJECTIVES: Previous research has highlighted the role of dysfunctional reasoning processes (i.e. "inferential confusion") in the development and maintenance of Obsessive-Compulsive Disorder (OCD). Inferential confusion has previously been found to be a unique predictor of OC symptoms and has shown specificity for OCD. However, these findings have primarily relied on a single self-report questionnaire, and only a limited number of experimentations have been conducted to establish the specificity of inferential confusion to OCD with alternate measures. The current paper demonstrates the relationship of inferential confusion with OCD symptoms in clinical samples by using a task-based measure of inferential confusion. METHODS: Sixty-four OCD participants, as well as thirty anxious and thirty-four healthy controls completed the recently developed Dysfunctional Reasoning Processes Task (DRPT) and related measures. Thirty-five OCD participants then completed sixteen sessions of cognitive-behavioural therapy (CBT) and completed the same measures post-treatment. RESULTS: As predicted, dysfunctional reasoning was significantly more elevated for those with OCD relative to control groups. Reduced levels of dysfunctional reasoning during CBT were significantly associated with successful treatment outcome. LIMITATIONS: Clinical implications should be interpreted with caution due to the relatively small sample size. CONCLUSIONS: Our findings support the notion that inferential confusion is an important cognitive factor particularly relevant to OCD that needs to be directly addressed as a mechanism of change in CBT.

RESUMO

Previous research has shown that vulnerable self-themes and feared self-perceptions may play an important role in the development and maintenance of obsessive-compulsive disorder (OCD). In particular, the recently validated Multidimensional Version of the Fear-of-Self Questionnaire (FSQ-MV) has shown strong relationships with OCD symptoms independent of cognitive constructs and negative mood in non-clinical samples. The current study aimed to further evaluate the validity and reliability of a Persian version of the FSQ-MV in OCD patients (N = 300), as well as non-clinical individuals (N = 300). Participants completed a set of scales evaluating feared self-perceptions and OCD-related symptoms/conditions. The results showed that the Persian version of the FSQ-MV replicated the three-factor structure of the original scale in non-clinical and OCD patients. The FSQ-MV and its subscales had excellent reliability. Additionally, the FSQ-MV was significantly associated with related cognitive constructs, as well as OCD symptoms and their severity, in both samples. The feared self, especially the corrupted feared self, was a significant unique predictor of OC symptomology, especially for repugnant obsessions, and OCD severity. The study confirmed the validity and reliability of the Persian version of the FSQ-MV. Moreover, cognitive conceptualizations may benefit from a consideration of the feared self in OCD, which may play an important role in its development, maintenance and severity.

RESUMO

INTRODUCTION: Inference-based cognitive-behavioral therapy (I-CBT) is a specialized psychological treatment for obsessive-compulsive disorder (OCD) without deliberate and prolonged exposure and response prevention (ERP) that focuses on strengthening reality-based reasoning and correcting the dysfunctional reasoning giving rise to erroneous obsessional doubts and ideas. OBJECTIVE: The present study aimed to evaluate the effectiveness of I-CBT through a comparison with appraisal-based cognitive behavioral therapy (A-CBT) and an adapted mindfulness-based stress reduction (MBSR) intervention. METHODS: This was a two-site, parallel-arm randomized controlled trial (RCT) comparing I-CBT with A-CBT. The MBSR intervention acted as a non-specific active control condition. Following formal evaluation, 111 participants diagnosed with OCD were randomly assigned. The principal outcome measure was the Yale-Brown Obsessive-Compulsive Scale. RESULTS: All treatments significantly reduced general OCD severity and specific symptom dimensions without a significant difference between treatments. I-CBT was associated with significant reductions in all symptom dimensions at post-test. Also, I-CBT led to significantly greater improvement in overvalued ideation, as well as significantly higher rates of remission as compared to MBSR at mid-test. CONCLUSIONS: I-CBT and MBSR appear to be effective, alternative treatment options for those with OCD that yield similar outcomes as A-CBT. I-CBT may have an edge in terms of the rapidity by which patients reach remission, its generalizability across symptom dimension, its potentially higher level of acceptability, and effectiveness for overvalued ideation. Future research is needed to assess whether additional alternative treatments options can help to increase the number of people successfully treated.

RESUMO

Cognitive models of obsessive-compulsive disorder (OCD) posit the relevance of the self in OCD, although the nature of this association is still unclear. We aimed to explore actual and feared selves and its association with obsessions and intrusions in a group of OCD patients. A group of 58 patients with OCD identified their most upsetting obsession and intrusion (non-clinical obsession) experienced in the past 3 months. These cognitions were classified as either moral-based or autogenous (obsessions n = 32; intrusions n = 26) or non-moral-based or reactive, depending on their content. Next, patients described their actual self and their feared self, that is, the person they feared being or becoming, and whether they believed these descriptions were associated with their obsessions/intrusions. Results indicate that individuals with OCD described themselves as insecure, anxious and fearful, but also as good and nice. They particularly feared a selfish, aggressive, bad, liar, coward, insecure and arrogant self. Two-thirds of the patients believed that their obsessions said something about their actual self (65.52%) and that their obsessions brought them closer to the person they do not want to be (62.06%). A third of patients believed their intrusions said something about their actual self (actual self: 30.35%; feared self: 25%), which was a significantly lower percentage than for obsessions. These associations existed independent from the content of the obsession and/or intrusion, although patients with obsessions with moral-based contents more often tended to believe that their obsessions brought them closer to the person they do not want to be. Results suggest the relevance of the real and feared selves in the maintenance of obsessions.

RESUMO

The present study aimed to compare a group of patients with obsessive-compulsive disorder (OCD; N = 270) before and during COVID-19 on specific obsessive-compulsive (OC) symptom dimensions and symptom severity. In addition, the study aimed to evaluate the associations of COVID-19-related stress responses with change in OC symptom dimensions and severity of symptoms as the result of the pandemic. Results showed that patients with OCD had higher scores on all OC symptom dimensions and symptom severity during the pandemic as compared to their scores from before the pandemic. Thus, the effect of COVID-19 is not limited to an increase in fears of contamination alone, but occurs across other symptom dimensions, including responsibility for harm, unacceptable thoughts, and symmetry. In addition, regression analyses indicated that COVID-19-related stress responses significantly predicted the observed increase in specific OC symptom dimensions and general severity, after controlling for pre-COVID-19 scores of symptoms and severity. The increase of symptoms as the result of COVID-19 might be best understood in the context of a non-specific stress-related response similar to the effects observed in non-clinical and other clinical populations.

RESUMO

In recent years, cognitive-behavioural models of OCD have increasingly recognized the potential role of feared possible selves in the development and maintenance of OCD, while simultaneously re-examining factors that have historically been linked to self-perceptions in OCD. The current article describes the development and validation of a multidimensional version of the Fear of Self Questionnaire (FSQ-EV) in a non-clinical (N = 626) and clinical OCD sample (N = 79). Principal component analyses in the non-clinical sample revealed three conceptually and factorially distinct components revolving around a feared corrupted possible self, a feared culpable possible self and a feared malformed possible self. The questionnaire showed a strong internal inconsistency, and good divergent and convergent validity, including strong relationships to obsessional symptoms. In particular, the corrupted feared self predicted OCD symptoms independently from depression and other related self-constructs and obsessive beliefs, while also strongly interacting with importance and control of thoughts in the prediction of almost all specific symptoms of OCD. Results are consistent with the notion that self-constructs can be conceptually and empirically distinguished from obsessive beliefs and appraisals with significant potential to improve our understanding of OCD and related disorders.

RESUMO

Obsessive-compulsive disorder (OCD) patients are known to have various functional abnormalities in prefrontal and motor areas. Given the presence of compulsions in many OCD patients, impaired response preparation processes could be a core feature of OCD. Yet, these processes remain understudied from a neurophysiological standpoint. Nineteen OCD patients were matched on age and sex to 19 healthy controls. Continuous EEG was recorded in all participants during a stimulus-response compatibility task. EEG from electrodes C3 and C4 was then averaged into stimulus- and response-locked LRPs. We compared both groups on various LRP measures, such as the LRP onset, the Gratton dip, and the maximum LRP peak. OCD patients showed significantly larger LRP peak than healthy controls, as well as larger Gratton dip. However, there was no group difference regarding LRP onset. Among OCD patients, it seems that motor regions are overactive during response preparation. Such overactivity was found for both incorrect responses that are aborted before execution and responses that are truly executed. These results suggest that regulation of sensorimotor activity should be addressed in the treatment of OCD.

RESUMO

BACKGROUND AND OBJECTIVES: Inferential confusion (IC) entails confusing an imagined possibility with a sensory-based possibility, and acting upon the imagined possibility as if it was real. Although IC was formulated in the context of obsessive-compulsive disorder (OCD), this reasoning bias has shown to be relevant to other obsessive-compulsive spectrum disorders, such as eating disorders (EDs). The goal of this study was to induce IC experimentally in individuals with EDs relative to healthy controls (HC). METHODS: Thirty-six women (ED group, n = 18; HC group, n = 18) were assigned to one of two experimental conditions: in the High IC condition, participants watched ED-themed videos with key sequences missing - provoking a distrust of the senses and lending more space for the imagination, thus triggering IC. In the Low IC condition, participants watched videos without sequences missing. Participants completed measures of IC, negative affect and compulsive behaviors after watching the videos. RESULTS: One-way ANOVA indicated that ED participants assigned to the High IC condition reported a greater urge to engage in compulsive behaviors. ED participants also neutralized more after watching the videos and endorsed higher trait IC. LIMITATIONS: There was no clinical control group. CONCLUSIONS: These findings suggest that individuals with EDs display a greater vulnerability to IC, as they are more prone to compulsive behaviors when IC is triggered. This investigation may foster our understanding of the relationship between EDs and OCD through the examination of cognitive factors that are implicated in both disorders.

RESUMO

OBJECTIVE: Some cognitive models of obsessive-compulsive disorder (OCD) posit that intrusions exist on a continuum with obsessions; others consider that they may be unrelated phenomena that differ in the context where they occur. We aimed to examine and compare, at two different moments, the context of the occurrence of intrusions and obsessions. METHOD: Sixty-eight patients with OCD completed an interview appraising their most upsetting obsession and intrusion. RESULTS: At their onset, the obsessions/intrusions were associated with experiencing negative emotional states and life events, and they were more likely to appear in "inappropriate" contexts. The context of the obsessions/intrusions differed the last time they were experienced. Autogenous obsessions/intrusions occurred more frequently in contexts with an indirect link. CONCLUSIONS: The context distinguishes between intrusions and obsessions, not when they emerge, but when the obsession is already established. The results support that there is a continuum or progression from intrusions to obsessions.

RESUMO

This communication explores unique characteristics of obsessive-compulsive disorder (OCD) in the context of the current coronavirus pandemic. When do irrational fears of contamination as seen in OCD start to diverge from rational fears and behaviors? The current paper argues that the personal meaning attributed to viruses and germs, including their personification as entities that possess human-like characteristics, allows them to threaten and violate an individual's identity. Specifically, it suggests that fears of contamination become obsessional when the threat of viruses and germs becomes personal, not solely in terms of its objective outcomes, but in how these life forms are able to threaten the self as the result of a fear of inner corruption characterizing those with OCD. The person with OCD may act as if, or believe that they are acting upon reality when they fear contagion, but are in effect only acting upon an underlying fear of inner corruption that is confused with reality itself. The current paper concludes with some clinical recommendations on how to treat obsessional fears of contamination in the context of the current pandemic.

RESUMO

The purposes of this research were (1) to analyse the psychometric properties of the Inferential Confusion Questionnaire-Expanded Version (ICQ-EV) in a Spanish population; (2) to explore the role of inferential confusion in obsessive-compulsive disorder (OCD); and (3) to compare the inferential confusion construct in nonclinical and clinical samples. A sample of 342 nonclinical participants and 66 patients with OCD completed the ICQ-EV Spanish adaptation as well as a set of questionnaires. Results confirmed a good fit of the ICQ-EV Spanish version to the original unifactorial structure and excellent internal consistency and test-retest reliability. Moreover, results confirmed that the ICQ-EV predicts Obsessing, Checking, Washing, and Hoarding symptoms, independently of the contribution of dysfunctional beliefs. In addition, OCD patients scored significantly higher on the ICQ-EV than nonclinical participants. The Spanish version of the ICQ-EV is a reliable instrument to assess inferential confusion, and further support is provided for the relevance of the inferential confusion construct in OCD.

RESUMO

Cognitive confidence, a type of metacognition referring to confidence in one's cognitive abilities (e.g., memory, perception, etc.), has been identified as relevant to eating disorders (EDs) using self-report measures. Repeated checking has been found to elicit decreases in perceptual confidence in obsessive compulsive disorder (OCD). The purpose of the present study was to experimentally investigate perceptual confidence, a type of cognitive confidence, in EDs. Specifically, this construct was investigated in the context of body checking, a behaviour with similarities to compulsive checking as observed in OCD. Women with bulimia nervosa (BN; n = 21) and healthy controls (HC; n = 24) participated in the study. There were no group differences with regards to perceptual confidence at baseline F(1, 43) = 0.5, p = 0.48, ηp2 = 0.01, but a significant difference was observed post-checking F(1, 43) = 7.79, p = 0.008, ηp2 = 0.15, which was accounted for by significant decreases in perceptual confidence in the BN group F(1, 43) = 13.31, p < 0.001, ηp2 = 0.24. Similar to compulsive checking in OCD, body checking may paradoxically decrease confidence regarding one's appearance. LEVEL OF EVIDENCE: Level I, experimental study.

RESUMO

The inference-based approach (IBA) is one cognitive model that aims to explain the aetiology and maintenance of obsessive-compulsive disorder (OCD). IBA theory suggests that certain reasoning processes lead an individual with OCD to confuse imagined possibilities with actual probabilities, a process termed inferential confusion. One such reasoning process is inverse reasoning, where hypothetical causes form the basis of conclusions about reality. Recently, we developed a task-based measure of inverse reasoning. In an online sample, we reported significant and positive associations between endorsement of inverse reasoning on this task and OCD symptomatology. We concluded that there was some support for the role of inverse reasoning in OCD but these results required extension using a between-groups design in a clinical sample. Therefore, the present study compared endorsement in inverse reasoning on this task between individuals diagnosed with OCD, anxiety and/or mood disorder (clinical controls), and healthy individuals (healthy controls). Relative to both control groups, the OCD group demonstrated significantly greater endorsement in inverse reasoning on scenarios where OCD relevant concerns were prompted. When non-OCD relevant concerns were involved, the OCD group only evidenced greater endorsement in inverse reasoning relative to the healthy control group. Implications for IBA theory are discussed.

RESUMO

OBJECTIVE: The potential causal and maintaining role of vulnerable self-themes and beliefs about the self in obsessive-compulsive disorder (OCD) have received increasing attention from cognitive-behavioural theorists. This interest was translated into the development of a self-report measurement of the feared self (the fear of who one might be or become), a construct theoretically and empirically pertinent to unwanted thoughts and impulses in OCD (i.e., repugnant obsessions). METHOD: The current study aimed to provide converging evidence on the relevance of the feared self in OCD, by examining whether improvements in symptoms associated with repugnant obsessions (measured on the Vancouver Obsessional Compulsive Inventory [VOCI] obsessions subscale) would be predicted by reduced feared self-perceptions (measured on the Fear-of-Self Questionnaire [FSQ]) in a sample of 93 patients receiving psychotherapy for OCD. RESULTS: Using a series of hierarchical linear regression models, we found that treatment-related reductions on the FSQ significantly and uniquely predicted reductions on the VOCI obsessions subscale and the contamination subscale. CONCLUSIONS: The current study thus replicated previous research suggesting the relevance of the feared possible self in psychological disorders such as OCD, where negative self-perception is a dominant theme. PRACTITIONER POINTS: Current results suggest that changes in feared self-perceptions may be the mechanism through which OCD symptoms improve via therapy. Interventions specifically aimed at changing feared self-perceptions may prove effective in improving cognitive-behavioural treatments for OCD. One limitation of the current study is the lack of behavioural measures of OCD to supplement self-report measures of OCD. Another limitation is that the small number of patients receiving some of the treatments precludes investigations into which treatments may be more effective in altering feared self-perceptions.

RESUMO

Increasingly, cognitive-behavioural models have been considering the role of beliefs about the self in the development and maintenance of obsessive-compulsive disorder (OCD), including sensitive domains of self-concept and feared self-perceptions. This has led to the development of the Fear of Self Questionnaire (FSQ; Aardema et al., ), which has shown strong internal consistency, divergent and convergent validity, and found to be a major predictor of unwanted thoughts and impulses (i.e., repugnant obsessions). The current study aimed to investigate fear of self-perceptions using the FSQ in an OCD sample (n = 144) and related psychological disorders (eating disorders, n = 57; body dysmorphic disorder, n = 33) in comparison to a non-clinical (n = 141) and clinical comparison group (anxiety/depressive disorders, n = 27). Following an exploratory factor analysis of the scale in the OCD sample, the results showed that participants with OCD in general did not score significantly higher on fear of self-perceptions than did the clinical comparison participants. However, consistent with previous findings, fear of self was highly characteristic among OCD patients with unwanted repugnant thoughts and impulses. In addition, fear of self-perceptions were significantly more elevated in those with eating or body dysmorphic disorders relative to the other non-clinical and clinical groups. The construct of a "feared possible self" may be particularly relevant in disorders where negative self-perception is a dominant theme, either involving concerns about one's inner self or concerns related to perceived bodily faults.
