Abstract
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.

Clinical outcomes of deep brain stimulation for obsessive-compulsive disorder: Insight as a predictor of symptom changes. Psychiatry Clin Neurosci 2024; 78:131-141. [PMID: 37984432 PMCID: PMC10952286 DOI: 10.1111/pcn.13619] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/03/2023] [Revised: 10/18/2023] [Accepted: 11/11/2023] [Indexed: 11/22/2023]
Abstract
AIM Deep brain stimulation (DBS) is a safe and effective treatment option for people with refractory obsessive-compulsive disorder (OCD). Yet our understanding of predictors of response and prognostic factors remains rudimentary, and long-term comprehensive follow-ups are lacking. We aim to investigate the efficacy of DBS therapy for OCD patients, and predictors of clinical response. METHODS Eight OCD participants underwent DBS stimulation of the nucleus accumbens (NAc) in an open-label longitudinal trial, duration of follow-up varied between 9 months and 7 years. Post-operative care involved comprehensive fine tuning of stimulation parameters and adjunct multidisciplinary therapy. RESULTS Six participants achieved clinical response (35% improvement in obsessions and compulsions on the Yale Brown Obsessive Compulsive Scale (YBOCS)) within 6-9 weeks, response was maintained at last follow up. On average, the YBOCS improved by 45% at last follow up. Mixed linear modeling elucidated directionality of symptom changes: insight into symptoms strongly predicted (P = 0.008) changes in symptom severity during DBS therapy, likely driven by initial changes in depression and anxiety. Precise localization of DBS leads demonstrated that responders most often had their leads (and active contacts) placed dorsal compared to non-responders, relative to the Nac. CONCLUSION The clinical efficacy of DBS for OCD is demonstrated, and mediators of changes in symptoms are proposed. The symptom improvements within this cohort should be seen within the context of the adjunct psychological and biopsychosocial care that implemented a shared decision-making approach, with flexible iterative DBS programming. Further research should explore the utility of insight as a clinical correlate of response. The trial was prospectively registered with the ANZCTR (ACTRN12612001142820).

Abstract
Disruption of conscious access contributes to the advent of psychotic symptoms in schizophrenia but could also explain lack of insight in other psychiatric disorders. In this study, we explored how insight and psychotic symptoms related to disruption of consciousness. We explored consciousness in patients with schizophrenia, patients with obsessive-compulsive disorder (OCD) with good vs. poor insight and matched controls. Participants underwent clinical assessments and performed a visual masking task allowing us to measure individual consciousness threshold. We used a principal component analysis to reduce symptom dimensionality and explored how consciousness measures related to symptomatology. We found that clinical dimensions could be well summarized by a restricted set of principal components which also correlated with the extent of consciousness disruption. More specifically, positive symptoms were associated with impaired conscious access in patients with schizophrenia whereas the level of insight delineated two subtypes of OCD patients, those with poor insight who had consciousness impairments similar to patients with schizophrenia, and those with good insight who resemble healthy controls. Our study provides new insights about consciousness disruption in psychiatric disorders, showing that it relates to positive symptoms in schizophrenia and with insight in OCD. In OCD, it revealed a distinct subgroup sharing neuropathological features with schizophrenia. Our findings refine the mapping between symptoms and cognition, paving the way for a better treatment selection.

Abstract
OBJECTIVE Describe and compare the clinical profile of schizophrenic patients with and without obsessive-compulsive symptoms and obsessive-compulsive disorder (OCD) patients. METHODS A descriptive and analytical cross-sectional study was carried out at the psychiatry department of Hassan II University Hospital in Fez over 12 months to compare three groups of patients: "schizo-obsessive" (n=32), "schizophrenia" (n=34), and "OCD" (n=46). All participants (n=112) were assessed using the mini-international neuropsychiatric interview (MINI), the Yale-Brown obsessive-compulsive scale (Y-BOCS), the Brown assessment of beliefs scale (BABS), the Hamilton anxiety rating scale (HAM-A), the Beck's depression inventory (BDI-II), the positive and negative syndrome scale (PANSS), and the clinical global impressions-severity scale (CGI-S). RESULTS The "schizo-obsessive" group differed from the "schizophrenia" group in: more severe psychotic symptoms (mean=64.16±17.049, P<0.001), higher anxiety (mean=8.87±5,655, P<0.001) and depression (mean=7.50±5.989, P<0.001) scores, more prevalent suicide attempts (46.9%), higher illness severity score (mean=5.13±1.157, P=0.02), and more professional disinsertion (78.1%). The "schizo-obsessive" group (mean= 14.47±3.388) had significantly poor insight (P<0.001) compared to the "OCD" group (mean= 8.35±4.542). There were similarities in the obsessive and compulsive themes between the "schizo-obsessive" and the "OCD" groups, with no significant difference of severity (P=0.26). CONCLUSION A careful assessment of obsessive symptomatology is essential in schizophrenia for better patient management and prognosis.

Abstract
Obsessive-compulsive disorder (OCD) is a chronic disabling disease with often unsatisfactory therapeutic outcomes. The fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) has broadened the diagnostic criteria for OCD, acknowledging that some OCD patients may lack insight into their symptoms. Previous studies have demonstrated that insight can impact therapeutic efficacy and prognosis, underscoring its importance in the treatment of mental disorders, including OCD. In recent years, there has been a growing interest in understanding the influence of insight on mental disorders, leading to advancements in related research. However, to the best of our knowledge, there is dearth of comprehensive reviews on the topic of insight in OCD. In this review article, we aim to fill this gap by providing a concise overview of the concept of insight and its multifaceted role in clinical characteristics, neuroimaging mechanisms, and treatment for OCD.

Abstract
BACKGROUND Poor insight in obsessive-compulsive disorder (OCD) is associated with higher symptom severity, more comorbidities, and worse response to treatment. This study aimed to elucidate underlying mechanisms of poor insight in OCD by exploring its neurobiological correlates. METHODS Using a symptom provocation task during functional magnetic resonance imaging, we compared brain activation of patients with poor insight (n = 19; 14 female, 5 male), good/fair insight (n = 63; 31 female, 32 male), and healthy control participants (n = 42; 22 female, 20 male) using a Bayesian region-of-interest and a general linear model whole-brain approach. Insight was assessed using the Overvalued Ideas Scale. RESULTS Compared with patients with good/fair insight and healthy control participants, patients with OCD and poor insight showed widespread lower task-related activation in frontal areas (subgenual anterior cingulate cortex, ventromedial prefrontal cortex, dorsolateral prefrontal cortex, ventrolateral prefrontal cortex, supplementary motor area, precentral gyrus), parietal areas (posterior parietal cortex, precuneus), and the middle temporal gyrus and insula. Results were not driven by interindividual differences in OCD symptom severity, medication usage, age of disorder onset, or state distress levels. CONCLUSIONS During symptom provocation, patients with OCD and poor insight show altered activation in brain circuits that are involved in emotional processing, sensory processing, and cognitive control. Future research should focus on longitudinal correlates of insight and/or use tasks that probe emotional and sensory processing and cognitive control.

Abstract
Objective Patients with obsessive-compulsive disorder (OCD) and poor insight show higher symptom severity, lower quality of life (QoL), and a reduced treatment response compared to patients with good insight. Little is known about changes in insight. This study explored the course of insight and its association with OCD severity and QoL among 253 patients with OCD participating in the prospective naturalistic Netherlands Obsessive Compulsive Disorder Association (NOCDA) Study. Results In 70% of the participants with available insight data, the level of insight changed during the four-year course. Insight was most variable in participants with poor insight. Improvement of insight scores was statistically significantly associated with improvement of Y-BOCS scores (r = 0.19), but not with changes in QoL scores. Change in insight in the first 2 years was not statistically significantly predictive of OCD severity or QoL at four-year follow-up. Conclusion These findings suggest that patients' levels of insight may change during the natural four-year course of OCD and that improvement in the level of insight have a positive association with improvement in OCD severity.

Abstract
Individuals with mental disorders possess varying levels of clinical insight-the degree to which one understands that they are afflicted with a mental disorder and that their symptoms are manifestations of this psychopathology. Although clinical insight in OCD is thought to play an especially important role in determining various clinical characteristics and treatment outcomes, insight has not been sufficiently addressed developmentally, the importance of which this review will elucidate. Findings from this review suggest that clinical insight is typically associated with more complex cases and worse treatment outcomes across the life course, and also reveal nuances between pediatric and adult OCD cases with low insight. Implications of these findings, future research directions, and recommendations for the field are discussed.

Abstract
Obsessive-compulsive disorder (OCD) is a chronic psychiatric condition characterized by the presence of obsessions, compulsions, or both. Historically OCD was associated with good insight. However, there are more categories to the degrees of insight in OCD patients, namely good, fair, poor, absent, or delusional beliefs. It is also important to note that insight can fluctuate circumstantially. We describe a rare case of first-episode psychosis of undetermined cause presenting with suicidal ideation. After continued treatment, it was discovered to be previously undiagnosed OCD with poor insight.

Abstract
Serotonin reuptake inhibitor (SRI) medications are well established as first-line pharmacotherapeutic treatment for Obsessive-Compulsive Disorder (OCD). However, despite the excellent safety profile and demonstrated efficacy of these medications, a substantial proportion of individuals with OCD fail to attain sufficient benefit from SRIs. In this narrative review, we discuss clinical features of OCD that have been associated with poorer response to SRIs, and we present pharmacotherapeutic interventions that have been explored as augmenting or alternative treatments for treatment-resistant OCD. We additionally highlight non-SRI interventions for OCD that are currently under investigation. Pharmacotherapeutic interventions were identified via expert consensus. To assess the evidence base for individual pharmacotherapies, targeted searches for relevant English-language publications were performed on standard biomedical research databases, including MEDLINE. Information relevant to ongoing registered clinical trials in OCD was obtained by search of ClinicalTrials.gov. Pharmacotherapies are grouped for review in accordance with the general principles of Neuroscience-based Nomenclature (NbN). Clinical features of OCD that may suggest poorer response to SRI treatment include early age of onset, severity of illness, duration of untreated illness, and the presence of symmetry/ordering or hoarding-related symptoms. Based on evolving pathophysiologic models of OCD, diverse agents engaging serotonin, dopamine, norepinephrine, glutamate, and anti-inflammatory pathways have been explored as alternative or adjunctive therapies for treatment-resistant OCD and have at least preliminary evidence of efficacy. Medications with dopamine antagonist activity remain the most robustly evidence-based of augmenting interventions, yet dopamine antagonists benefit only a minority of those who try them and carry elevated risks of adverse effects. Interventions targeting glutamatergic and anti-inflammatory pathways are less well evidenced, but may offer more favorable benefit to risk profiles. Ongoing research should explore whether specific interventions may benefit individuals with particular features of treatment-resistant OCD.

Abstract
Insight impairment contributes significantly to morbidity in psychiatric disorders. The neurologic concept of anosognosia, reflecting deficits in metacognitive awareness of illness, is increasingly understood as relevant to psychopathology, but has been little explored in psychiatric disorders other than schizophrenia. We explored anosognosia as an aspect of insight impairment in n = 71 individuals with DSM-5 hoarding disorder. We used a standardized clutter severity measure to assess whether individuals with hoarding disorder underreport home clutter levels relative to independent examiners. We then explored whether underreporting, as a proxy for anosognosia, is predicted by clinical or neurocognitive behavioral measures. We found that individuals with hoarding disorder underreport their clutter, and that underreporting is predicted by objective severity of clutter. In an n = 53 subset of participants, we found that underreporting is predicted by altered performance on tests of cognitive control and inhibition, specifically Go/No-Go and Stroop tests. The relation of underreporting to objective clutter, the cardinal symptom of hoarding disorder, suggests that anosognosia may reflect core pathophysiology of the disorder. The neurocognitive predictors of clutter underreporting suggest that anosognosia in hoarding disorder shares a neural basis with metacognitive awareness deficits in other neuropsychiatric disorders and that executive anosognosia may be a transdiagnostic manifestation of psychopathology.

Abstract
The aim was to compare insight levels into obsessive-compulsive symptoms (OCS), and metacognitions of patients with obsessive-compulsive disorder (OCD) and with schizophrenia with comorbid OCD (SZ-OCD). Thirty OCD patients and 30 SZ-OCD patients were evaluated; no significant difference was found between the groups in the Brown Assessment of Beliefs Scale (BABS) and the Metacognition Questionnaire-30 (MCQ-30). When all patients were divided into two groups regardless of the presence or absence of schizophrenia as "good insight" and "poor or no insight," the MCQ-30 total score was found to be higher in the "poor or no insight" group and showed a significant but moderate positive correlation with the BABS score. This study supports that the level of insight into OCS in SZ-OCD is not significantly different from patients with OCD. Metacognitions differ not according to the distinction between OCD and SZ-OCD but according to the level of insight in whole OCD sample.

Abstract
BACKGROUND Previous studies examining potential relationships of impaired insight with severity obsessive-compulsive (O-C) symptoms and depressive symptoms in patients diagnosed with obsessive-compulsive disorder (OCD) have produced mixed results. Here, we examined differences in these clinical characteristics and their changes after treatment in adult patients with OCD who have poor insight (OCD-PI) versus in those who have good insight (OCD-GI). METHODS Fifty-nine full-text articles were screened for eligibility with 20 studies ultimately being included in the present meta-analysis. RESULTS The OCD-PI and OCD-GI groups differed from each other with respect to O-C symptom (p < 0.001, g > 0.7) and depressive symptom (p < 0.001, g = 0.614) severity. Significant and moderate correlations were observed between insight and treatment outcomes (O-C symptoms, r = 0.33; depressive symptoms, r = 0.47). Exploratory meta-regression showed that methodological factors influenced the magnitudes of inter-group O-C symptom differences. CONCLUSIONS The current meta-analysis indicates that poorer insight is associated with more severe O-C and depression, and less improvement of symptoms in patients with OCD. Insight impairment may be a critical and core OCD-related deficit.

Abstract
BACKGROUND AND HYPOTHESIS Impaired insight into the illness and its consequences is associated with poor outcomes in schizophrenia. While transcranial direct current stimulation (tDCS) may represent a potentially effective treatment strategy to relieve various symptoms of schizophrenia, its impact on insight remains unclear. To investigate whether tDCS would modulate insight in patients with schizophrenia, we undertook a meta-analysis based on results from previous RCTs that investigated the clinical efficacy of tDCS. We hypothesize that repeated sessions of tDCS will be associated with insight improvement among patients. STUDY DESIGN PubMed and ScienceDirect databases were systematically searched to identify RCTs that delivered at least 10 tDCS sessions in patients with schizophrenia. The primary outcome was the change in insight score, assessed by the Positive and Negative Syndrome Scale (PANSS) item G12 following active tDCS sessions as opposed to sham stimulation. Effect sizes were calculated for all studies and pooled using a random-effects model. Meta-regression and subgroup analyses were conducted. STUDY RESULTS Thirteen studies (587 patients with schizophrenia) were included. A significant pooled effect size (g) of -0.46 (95% CI [-0.78; -0.14]) in favor of active tDCS was observed. Age and G12 score at baseline were identified as significant moderators, while change in total PANSS score was not significant. CONCLUSIONS Ten sessions of active tDCS with either frontotemporoparietal or bifrontal montage may improve insight into the illness in patients with schizophrenia. The effect of this treatment could contribute to the beneficial outcomes observed in patients following stimulation.

Abstract
There is little doubt that schizophrenia (SZ) and obsessive-compulsive disorder (OCD) are among the most severe disorders to impact humanity. They are both common, significantly disabling and have the tendency to strike during critical developmental periods in a young person's life. Schizophrenia affects approximately 1% of the global population and OCD has a lifetime prevalence of between 2% and 3% in the general population. The comorbidities in both SZ and OCD are common and frequently diagnosed, and research has generally found that comorbidities are associated with conditions that are more complex to diagnose and treat, and often result in less favorable prognoses. We review the research that has taken place regarding the co-occurrence of SZ and OCD, discuss it's theoretical conceptulization and clinical differentiation and diagnosis. We then propose recommendations for the best practice of cognitive behavioral therapy in this difficult population, as well as areas that need exploration for future research.

Understanding why people with OCD do what they do, and why other people get involved: supporting people with OCD and loved ones to move from safety-seeking behaviours to approach-supporting behaviours.

Abstract
Abstract
The distress inherent in obsessive compulsive disorder (OCD) can often lead to partners, family members and friends becoming entangled with the OCD in terms of being drawn into performing certain behaviours to try and reduce the distress of their loved one. In the past this has often been referred to somewhat pejoratively as collusion, or more neutrally as accommodation. In this paper we emphasise that this is usually a natural human response to seeing a loved one in distress and wanting to help. This paper provides detailed clinical guidance on how to understand this involvement and how to include others in the treatment of OCD along with practical tips and hints around potential blocks that may require troubleshooting. It also details the relatively recently introduced concept of approach-supporting behaviours, and provides guidance on how to distinguish these from safety-seeking behaviours. The ‘special case’ of reassurance seeking is also discussed.
Key learning aims
(1)
To illustrate the importance of understanding the person’s OCD beliefs ‘from the inside’ including the internal logic that leads to specific behaviours.
(2)
To understand the ways that key individuals in the lives of people with OCD can become entangled with the OCD (through the best of intentions) and to provide practical clinical guidance for CBT therapists around how to engage and work with these individuals in the lives of people with OCD.
(3)
To explain and delineate the idea of approach-supporting behaviours, distinguishing these from safety-seeking behaviours.
(4)
To distinguish the interpersonal component of reassurance from the neutralisation component and provide guidance on how we can help family members to replace reassurance with something that is equally or more supportive whilst not maintaining the OCD.

Abstract
Obsessive-compulsive symptoms are frequent in schizophrenia-spectrum disorders and often cause differential diagnostic challenges, especially in first-contact patients. Drawing upon phenomenology of cognition, we critically review classic and contemporary psychopathological notions of obsessive-compulsive phenomena and discuss their relevance for differential diagnosis between obsessive-compulsive disorder (OCD) and schizophrenia-spectrum disorders. The classic psychopathological literature defines true obsession as intrusions with intact resistance and insight and regards these features as essential to the diagnosis of OCD. In schizophrenia, the classic literature describes pseudo-obsessive-compulsive phenomena characterized by lack of resistance and an affinity with other symptoms such as thought disorder and catatonia. By contrast, the notions of obsession and compulsion are broader and conceptually vague in current diagnostic systems and research instruments. Here, these phenomena overlap with delusions as well as various subjective and behavioral anomalies, which we discuss in detail. Furthermore, we examine a link between obsessive-compulsive phenomena and disturbances of basic structures of experience in schizophrenia-spectrum disorders addressed in contemporary psychopathological research. We suggest that these experiential alterations have relevance for differential diagnosis and early detection in this complex symptom domain.

Abstract
BACKGROUND Studies investigating obsessive-compulsive disorder from an ethological approach have highlighted a specific motor pattern of compulsive rituals with respect to corresponding ordinary behaviors. Particularly, compulsive motor profile is built through the repetition of acts, with prevalence of nonfunctional ones and redirection of attention to its basic structural units. These formal features would characterize ritual behavior throughout evolution, from nonhuman animals to human cultures. However, no study to date has investigated a possible relationship between such motor profile and underlying psychopathology. Therefore, the first objective of the study was to confirm previous findings on a larger sample size of obsessive patients; the second objective was to elucidate whether motor profile might be associated with obsessive-compulsive psychopathology and/or prepsychotic symptoms of schizophrenia. METHODS Twenty-one obsessive-compulsive outpatients provided a videotape of their rituals. An equal number of healthy controls, matched for sex and age, were registered for corresponding ordinary acts. Obsessive patients were administered the Yale-Brown Obsessive-Compulsive Scale, the Brown Assessment of Beliefs Scale, the Hamilton Rating Scale for Depression, and the Frankfurt Complaint Questionnaire. RESULTS The results of the present study confirm that ritual compulsions present a specific motor structure characterized by repetition of both functional and nonfunctional acts and their longer duration. Such a motor pattern is independent from obsessive-compulsive psychopathology, whereas it results specifically associated with prepsychotic symptoms of schizophrenia. CONCLUSIONS We argue that this association may reflect the adaptive significance of ritual behavior across evolution, that is, its homeostatic function in conditions of unpredictability.

Abstract
BACKGROUND Medications currently recommended for the treatment of Obsessive-Compulsive Disorder (OCD) usually decrease the severity of the symptoms by 20-30%; however, 40-60% of OCD patients do not achieve a satisfactory response. Our main objective was to investigate the effectiveness of memantine, a non-competitive N-Methyl-D-aspartate (NMDA) receptor antagonist, as an adjunct therapy to sertraline, a selective serotonin reuptake inhibitor (SSRI), to improve severity of symptoms and executive function among patients with obsessive-compulsive disorder. METHODS Seventy patients with OCD according to the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) criteria, and a Yale-Brown obsessive compulsive scale (Y-BOCS) score of more than 21 were recruited to the study. They received sertraline (100 mg daily initially followed by 200 mg daily after week 4) and either memantine (10 mg twice daily) or placebo in a placebo controlled, double-blinded, parallel-group, clinical trial of 12 weeks. The primary outcome was OCD symptoms measured by the Y-BOCS. Moreover, executive function of participants was measured by the Wisconsin Card Sorting Test (WCST). RESULTS The total score, and obsession and compulsion subscales of Y-BOCS significantly dropped in both groups with no significant difference between the two groups. However, memantine group showed a greater response in the number of completed categories subscale of the WCST (p value<0.001). We did not observe any major adverse effects in any of the groups. CONCLUSION Memantine has an acceptable safety and tolerability in patients with OCD and might have a positive effect on their executive function. Nevertheless, the current results don`t support the efficacy of memantine as an adjunctive agent to sertraline for symptoms in patients with OCD. TRIAL REGISTRATION The trial was registered at the Iranian Registry of Clinical Trials on 04/10/2019 ( www.irct.ir ; IRCT ID: IRCT20170123032145N4).

Abstract
Insight is considered a multidimensional concept and, in the context of obsessive-compulsive disorder (OCD), impairment in insight has been widely reported to be associated with severity and other clinical and sociodemographic variables. However, the studies concerning insight in OCD have produced heterogenous data as a result of the scales used to measure insight. To overcome this heterogeneity, the study presented here used 4 different widely used and validated insight scales. The objective was to evaluate various aspects of insight using these scales to identify the relationships between different aspects of insight and clinical and sociodemographic variables to assess which scale or scales might possess greater efficiency in clinical practice. For this purpose, a descriptive, observational, and cross-sectional study of 81 patients in treatment in a mental health center was conducted. Patients were evaluated using the Brown Assessment of Beliefs Scale, the Overvalued Ideas Scale, the Scale of Unawareness of Mental Disorders, the Yale-Brown Obsessive Compulsive Scale, the Clinical Global Impressions Scale, the Global Assessment of Functioning Scale, and the Rey-Osterrieth Complex Figure Test. The results reported significant relationships between insight and scores on the Yale-Brown Obsessive Compulsive Scale (Thoughts, Compulsions, and Total scales), Clinical Global Impressions Scale, and the Global Assessment of Functioning Scale, and significant differences with regard to sex, level of education, working status, and course of the disorder. A correlation analysis was conducted to assess the relationships among the 4 insight scales. The results of this analysis suggest that the scales that measure insight in a multidimensional way (Brown Assessment of Beliefs Scale and Overvalued Ideas Scale) provide more information about the severity of the disorder in patients with OCD.

Abstract
PURPOSE Insight is currently considered to be responsible for 20% to 40% of the cases of ineffective obsessive-compulsive disorder (OCD) treatment. As 15% to 36% of patients with OCD have reduced insight, we aimed to identify some of the clinical determinants of insight in OCD. RESULTS Our sample consisted of 57 OCD patients, of which 34 men (59%) and 23 women (41%). All individuals completed a two-phase interview consisting of a clinical assessment, emotional awareness evaluation and insight measurement, using the Brown Assessment of Beliefs Scale (BABS). The insight score correlated significantly with negative emotion recognition (p < 0.0001) and empathic concern (p = 0.003). MAJOR CONCLUSIONS Our results support the hypothesis that insight in OCD is related to emotional awareness, specifically emotion recognition and empathic concern. Future research should investigate the extent to which poor insight and impaired emotional awareness can be modified by psychological or pharmacological therapies and whether this will enhance treatment response.

Abstract
Obsessive-compulsive disorder (OCD) is a chronic and disabling mental disorder characterized by the presence of obsessions and/or compulsions that cause major distress and impair important areas of functioning. About 9 out of 10 patients with OCD have comorbid psychiatric diagnoses. A high proportion of clinically diagnosed OCD patients fulfill diagnostic criteria of a schizophrenia spectrum disorder, to the point that significant evidence in the literature supports the existence and the clinical relevance of a schizo-obsessive spectrum of disorders, including schizotypal personality disorder (SPD) with OCD (schizotypal OCD). In this paper, we provide a brief but comprehensive analysis of the literature on the clinical coexistence between OCD and SPD. The clinical validity of the so-called schizotypal OCD is analyzed through a comprehensive investigation of the relationship between SPD features and obsessive-compulsive phenomena in clinical OCD samples. This review describes the potential connections between OCD and SPD on the epidemiological, sociodemographic, psychopathological, and clinical levels. SPD is commonly observed in OCD patients: about 10% of OCD patients have a full categorical diagnosis of SPD. Early clinical identification of SPD features-and, more generally, of psychotic features and personality disorders-in OCD patients is strongly recommended. In fact, a proper and early diagnosis with early treatment may have benefits for prognosis. However, although schizotypal OCD seems to have clinical and predictive validity, further neurobiological and genetic studies on etiological specificity are warranted.

Abstract
AIMS This study aimed to examine the (a) prevalence of various levels of insight among patients with obsessive-compulsive disorder (OCD) and (b) correlation of insight specifier (Diagnostic and Statistical Manual [DSM]-5) and other established measures of insight in OCD. METHODS One hundred and twenty-five outpatients with a diagnosis of OCD were assessed by Brown Assessment of Beliefs Scale (BABS) and DSM-IV's insight specifier. The insight specifier of DSM-5 was determined by item one ("conviction") of BABS. Dimensional Yale-Brown Obsessive-Compulsive Severity Scale was used to assess the frequency and severity of dimensional obsessive-compulsive (OC) symptoms. RESULTS The mean age of the participants was 31.2 (±11) years. Seventy-seven (61.6%) of the participants were men. There was a high correlation (r = 0.73) between the insight specifiers of DSM-5 and DSM-IV. Insight categories of DSM-5 had modest correlations with BABS total score and BABS-based insight categories. Significant associations were observed between the level of insight and comorbid psychotic illness, hoarding and symmetry dimensions of OC symptoms, severity of depressive, and OC symptoms. The first two associations were consistent across group comparisons (insight-groups based on DSM-IV and BABS) and correlation (with total BABS score). CONCLUSIONS Majority of the patients with OCD have good insight and application of different tools influence the assessment of insight in OCD. The DSM-5 insight specifier has strong and significant correlation with the DSM-IV's insight classification and categorization of insight by BABS.

Abstract
BACKGROUND Impaired clinical and cognitive insight are prevalent in schizophrenia and relate to poorer outcome. Good insight has been suggested to depend on social cognitive and metacognitive abilities requiring global integration of brain signals. Impaired insight has been related to numerous focal gray matter (GM) abnormalities distributed across the brain suggesting dysconnectivity at the global level. In this study, we test whether global integration deficiencies reflected in gray matter network connectivity underlie individual variations in insight. METHODS We used graph theory to examine whether individual GM-network metrics relate to insight in patients with a psychotic disorder (n = 114). Clinical insight was measured with the Schedule for the Assessment of Insight-Expanded and item G12 of the Positive and Negative Syndrome Scale, and cognitive insight with the Beck Cognitive Insight Scale. Individual GM-similarity networks were created from GM-segmentations of T1-weighted MRI-scans. Graph metrics were calculated using the Brain Connectivity Toolbox. RESULTS Networks of schizophrenia patients with poorer clinical insight showed less segregation (i.e. clustering coefficient) into specialized subnetworks at the global level. Schizophrenia patients with poorer cognitive insight showed both less segregation and higher connectedness (i.e. lower path length) of their brain networks, making their network topology more "random". CONCLUSIONS Our findings suggest less segregated processing of information in patients with poorer cognitive and clinical insight, in addition to higher connectedness in patients with poorer cognitive insight. The ability to take a critical perspective on one's symptoms (clinical insight) or views (cognitive insight) might depend especially on segregated specialized processing within distinct subnetworks.

Abstract
BACKGROUND Around 25 to 30% of patients with obsessive-compulsive disorder (OCD) do not respond to treatment. These patients have the longest duration of disease and the worst prognosis. Following years of research on this topic, insight has emerged as a potential explanation for this therapeutic resistance. Therefore, it has become important to characterize OCD patients with poor insight. Few studies have focused on the neuropsychological and cognitive characteristics of these patients. METHODS To help fill this gap, we divided 57 patients into two groups, one with good insight and the other with poor insight, assessed their neuropsychological functions-through a Rey's figure test, a California verbal learning test, a Toulouse-Piéron test and a Wisconsin Card Sorting Test (WCST)-and compared the results with those of a paired control group. RESULTS The statistical analysis, with a significance level of 95%, revealed differences in the executive function tests, and particularly in the WCST (p ≤ 0.001) and trail-making-test (TMT A/B) (p = 0.002). CONCLUSIONS These differences suggest that the neuropsychological profile of poor-insight patients is different from their good-insight counterparts, emphasize the role played by the executive functions in insight and highlights the need for more accurate neurocognitive research and treatment.

Abstract
Cotard's syndrome usually presents as combined symptoms occurring in a broad series of neurological, psychiatric, and medical disorders, being severe depression the most frequent. The syndrome is not classified as a distinct clinical entity in the nosological systems but appears solely as a clinical condition in case reports. Thus, the diagnosis of Cotard's syndrome mainly centres on the psychiatric interview and the ability of the clinician to recognise specific symptoms due to the absence of both clinical instruments and diagnostic criteria. Cotard's syndrome has never been described to date in patients with a history of obsessive-compulsive disorder (OCD). We report a case of a 49-year-old woman presenting obsessive symptoms and related compulsions for more than 30 years. Cotard's syndrome appeared after 3 years from a tragic event that had caused a psychological trauma. Such an occurrence may have contributed to worsening OCD and leading to a second major depressive episode followed by a suicidal attempt. Since then, the subject of our patient's obsessive thoughts changed, and the belief of being dead appeared. The repetitive and stereotyped thoughts caused severe distress, and accompanied the compulsive nature of reassurance seeking, temporarily beneficial to the anxiety arousing. The transition from obsession to delusion occurred when resistance was abandoned, and insight was lost. Once Cotard's syndrome had stabilised, OCD was no longer present. Additional distinctive features were the absence of psychiatric family history and the persistent nature of the affective psychosis. We concluded that Cotard's syndrome represented the evolution of the initial obsessive-compulsive disorder. Furthermore, we differentiated the clinical condition of our patient from other psychiatric diseases with similar clinical features. Larger-scale research is needed to consider topics other than comorbidity and also to explore significant elements of the patient's clinical history to discover what may influence the evolution and/or the persistence of the diseases.

Abstract
Abstract
Background
Medically unexplained oropharyngeal dysphagia (MUNOD) is a rare condition. It presents without demonstrable abnormalities in the anatomy of the upper aero-digestive tract or swallowing physiology. The aim of this case report is to discuss the unique presentation of OCD as chronic dysphagia.
Case presentation
A 65-year-old woman was admitted with dysphagia and weight loss in surgical department with history of undergoing repeated upper GI endoscopies and laryngoscopies. The patient was finally diagnosed to be suffering from chronic obsessive-compulsive disorder with poor insight and comorbid depression after 3 years of suffering and moving from hospital to hospital. The atypical presentation and poor insight were the major reasons for diagnostic difficulty in this particular case. The patient was given 60 mg fluoxetine and 2 mg risperidone which improved the patient’s symptoms by 40%.
Conclusion
This case explains the possibility of obsessive-compulsive disorder in patients presenting with unexplained somatic symptoms. It also demonstrated the importance of a timely psychiatric diagnosis and treatment and highlights the importance about awareness of psychiatric illness in doctor community which can reduce patient suffering and unnecessary invasive procedures.

Abstract
BACKGROUND Cognitive insight is defined as the ability to reflect upon oneself (i.e. self-reflectiveness), and to not be overly confident of one's own (incorrect) beliefs (i.e. self-certainty). These abilities are impaired in several disorders, while they are essential for the evaluation and regulation of one's behavior. We hypothesized that cognitive insight is a dynamic process, and therefore examined how it relates to temporal dynamics of resting state functional connectivity (FC) and underlying structural network characteristics in 58 healthy individuals. METHODS Cognitive insight was measured with the Beck Cognitive Insight Scale. FC characteristics were calculated after obtaining four FC states with leading eigenvector dynamics analysis. Gray matter (GM) and DTI connectomes were based on GM similarity and probabilistic tractography. Structural graph characteristics, such as path length, clustering coefficient, and small-world coefficient, were calculated with the Brain Connectivity Toolbox. FC and structural graph characteristics were correlated with cognitive insight. RESULTS Individuals with lower cognitive insight switched more and spent less time in a globally synchronized state. Additionally, individuals with lower self-reflectiveness spent more time in, had a higher probability of, and had a higher chance of switching to a state entailing default mode network (DMN) areas. With lower self-reflectiveness, DTI-connectomes were segregated less (i.e. lower global clustering coefficient) with lower embeddedness of the left angular gyrus specifically (i.e. lower local clustering coefficient). CONCLUSIONS Our results suggest less stable functional and structural networks in individuals with poorer cognitive insight, specifically self-reflectiveness. An overly present DMN appears to play a key role in poorer self-reflectiveness.

Abstract
BACKGROUND Based on the observed clinical overlap between obsessive-compulsive disorder (OCD) and schizophrenia (SCZ), both conditions may share, at least in part, common cognitive underpinnings. Among the cognitive deficits that could be involved, it has been hypothesized that patients share a failure in their abilities to monitor their own thoughts (source monitoring), leading to confusion between what they actually did or perceived and what they imagined. Although little is known regarding source-monitoring performances in patients with OCD, numerous studies in patients with SCZ have observed a relationship between delusions and/or hallucinations and deficits in both internal source- and reality-monitoring abilities. METHODS The present work compared source-monitoring performances (internal source and reality monitoring) between patients with OCD (n = 32), patients with SCZ (n = 38), and healthy controls (HC; n = 29). RESULTS We observed that patients with OCD and patients with SCZ displayed abnormal internal source-monitoring abilities compared to HC. Only patients with SCZ displayed abnormalities in reality monitoring compared to both patients with OCD and HC. CONCLUSIONS Internal source-monitoring deficits are shared by patients with OCD and SCZ and may contribute to the shared cognitive deficits that lead to obsessions and delusions. In contrast, reality-monitoring performance seems to differentiate patients with OCD from patients with SCZ.

Abstract
OBJECTIVE Insight and avoidance are commonly discussed factors in obsessive-compulsive disorder (OCD) that have demonstrated associations with increased severity as well as reduced treatment response in adults, but these factors have not been sufficiently examined in pediatric OCD. This study examined the impacts of avoidance, insight, and impairment recognition concordance on cognitive-behavioral therapy (CBT) outcomes as well as impacts of CBT on insight and avoidance in a large sample of youths affected by OCD. METHOD Data from 573 OCD-affected youths enrolled in CBT trials were aggregated. Children's Yale-Brown Obsessive-Compulsive Scale items measured treatment response, insight, and avoidance. Standardized differences between child and parent ratings of impairment were used to calculate impairment recognition concordance. Binary logistic regression was used to identify variables associated with treatment response. RESULTS Greater avoidance, limited child recognition of impairment, older age, and lower baseline severity predicted reduced likelihood of treatment response, but insight did not. Both insight and avoidance improved significantly following CBT. Response rates were lower when posttreatment insight and avoidance were worse. CONCLUSION Contrasting with prevailing belief, poor insight does not appear to limit CBT response potential in pediatric OCD. Avoidance and impairment recognition are understudied CBT response predictors and warrant further consideration in pediatric OCD. Clinicians should attend to these factors to optimize outcomes for children affected by this common, debilitating illness.

Abstract
Previous studies have reported clinical characteristics of hoarding disorder (HD), such as early onset, a chronic course, familiality, high unmarried rate, and high rates of comorbidities. However, clinical research targeting Japanese HD patients has been very limited. As a result, there is a low recognition of HD in Japan, leading to insufficient evaluation and treatment of Japanese HD patients. The aim of the current study was to delineate the clinical characteristics of Japanese HD patients. Thirty HD patients, 20 obsessive-compulsive disorder (OCD) patients, and 21 normal controls (NC) were targeted in this study. The HD group had a tendency toward higher familiality, earlier onset, and longer disease duration compared to the OCD group. In addition, the HD group showed a significantly higher unmarried rate than the NC group. The top two comorbidities in the HD group were major depressive disorder (56.7%) and attention-deficit/hyperactivity disorder (26.7%). The HD group had significantly higher scores on hoarding rating scales and lower scores on the Global Assessment of Functioning Scale than the other two groups. The current study showed a clinical trend in Japanese HD patients similar to previous studies in various countries, suggesting that HD may be a universal disease with consistent clinical symptoms.

Associations of cortical thickness, surface area and subcortical volumes with insight in drug-naïve adults with obsessive-compulsive disorder. NEUROIMAGE-CLINICAL 2019; 24:102037. [PMID: 31704545 PMCID: PMC6978222 DOI: 10.1016/j.nicl.2019.102037] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/30/2019] [Revised: 09/30/2019] [Accepted: 10/15/2019] [Indexed: 12/27/2022]
Abstract
• We first used the SBM method to explore the neuroanatomical basis underlying insight in OCD. • OCD-GI and OCD-PI displayed mostly shared, but partly distinct brain structural alterations. • Decreased cortical thickness in the left dmPFC, the left ACC and the right lateral parietal cortex was associated with poorer insight. • The potential effect of other clinical variables on the results has been ruled out.
Poor insight in obsessive-compulsive disorder (OCD) is associated with several adverse clinical outcomes. However, the neurobiological basis of this insight deficit is not clearly understood. The present study thus aimed to investigate associations of cortical thickness, cortical surface area and subcortical volumes with insight in a sample of drug-naïve adults with OCD. Forty-seven OCD patients and 42 healthy controls (HCs) underwent MRI scanning, depression and anxiety assessments. The Brown Assessment of Beliefs Scale (BABS) measured insight levels and patients were divided into two groups: poor insight (OCD-PI; n = 21), and good insight (OCD-GI; n = 26). Cortical thickness and surface area between groups were compared with whole-brain exploratory vertex-by-vertex analyses, while subcortical volumes were compared on a structure-by-structure basis. Partial correlation analyses were then performed to assess associations between regional cortical and subcortical measures and insight levels. OCD-GI and OCD-PI groups displayed partly shared, but also partly distinct brain structural alterations. Strikingly, OCD-PI showed decreased cortical thickness in the left superior frontal gyrus, left anterior cingulate cortex (ACC) and right inferior parietal gyrus, compared to both OCD-GI and HCs. Average cortical thickness extracted from these areas was further negatively correlated with BABS scores in the OCD-PI patients. Our findings suggest that poor insight in patients with OCD may have a neural substrate involving the left medial frontal and the right inferior parietal cortices.

Behav Res Ther 2019; 121:103449.

Abstract
Insight in obsessive-compulsive disorder (OCD) is assumed to fluctuate over time. However, temporal variations of insight and its correlates in OCD have never been empirically studied. We used ecological momentary assessment (EMA) to analyze the temporal variation of insight into the unreasonableness of the threat-related core belief (1), into the senselessness of compulsions to prevent this belief from occurring (2), and into the belief, itself, as being due to OCD (3). Furthermore, we analyzed whether worry, self-punishment and mindfulness are associated with these aspects of insight. A total of 50 OCD patients underwent EMA 10 times a day over 6 consecutive days. Data were analyzed using multilevel modelling. Results revealed that multiple time-points within individuals accounted for up to 51.4% of insight variance, indicating a substantial fluctuation of insight over time. Root mean square successive difference (rMSSD) scores indicated significantly higher fluctuation patterns in the doubt/checking dimension as compared to taboo thoughts throughout all aspects of insight. As hypothesized, self-punishment and mindfulness significantly predicted insight into the unreasonableness of the threat-related belief and the senselessness of compulsions to prevent this belief from occurring. Mindfulness demonstrated the greatest predictive value and remained significant after controlling for OC symptoms. Contrary to expectation, worry, as it was measured in our study, was not associated with insight. Besides providing evidence for insight fluctuation, our results indicate that mindfulness-based strategies might be beneficial for increasing insight in OCD.

Abstract
Studies indicate that approximately 9%-30% of adults diagnosed with obsessive-compulsive disorder have poor insight into their symptoms. That is, they fail to recognize the excessiveness or irrationality of the obsessive thoughts or their compulsive behaviors. Poor insight in OCD is associated with more severe symptoms, earlier age of illness onset, longer illness duration, and higher rates of comorbid depression. Moreover, some studies have also reported that patients with poor insight are less likely than are those with good or fair insight to respond to first-line treatments such as exposure and response prevention (ERP). Despite the clinical relevance of poor insight, very little research has focused on how to enhance therapy with strategies specifically used to target it. In this report, we use a case study to demonstrate how different techniques can be emphasized or integrated with standard ERP to improve treatment outcomes for this subset of patients.

Abstract
OBJECTIVE To review the available literature on obsessive-compulsive symptom (OCS)/obsessive-compulsive disorder (OCD) in patients with schizophrenia. METHODOLOGY Electronic searches were carried out to locate studies reporting various aspects of OCS/OCD in patients with schizophrenia. RESULTS Available evidence suggests that prevalence of OCS/OCD in patients with schizophrenia is much higher than prevalence in general population and it is seen in all the stages of schizophrenia, starting from at risk mental state to chronic/stabilisation/deficit phases. Symptom profile of OCS/OCD in schizophrenia is similar to that seen in patients with OCD only. Presence of OCS/OCD is associated with higher severity of symptoms of schizophrenia and more negative outcome. At present there is very limited data on the efficacy/effectiveness of various pharmacological measures and psychological interventions, for management of OCS/OCD in patients with schizophrenia. There is some evidence pointing towards beneficial effect of certain antipsychotics, antidepressants and cognitive behaviour therapy. Management of OCS/OCD in patients with schizophrenia involves proper assessment. If the OCS/OCD is related to use of particular antipsychotic use, initial attempt must be made to reduce the dose of antipsychotics, however, if this is not effective, than addition of a selective serotonin reuptake inhibitor (SSRIs) must be considered. If the OCS/OCD is not related to the use of antipsychotic medication, than depending up on the severity of psychotic symptoms, addition of SSRIs must be considered. CONCLUSION This review suggests that OCS/OCD is highly prevalent among patients with schizophrenia and there is limited good quality evidence to make any specific recommendations for management.

Abstract
Obsessive-compulsive disorder (OCD) is a debilitating mental illness characterized by an early onset and chronic course. Evidence from several lines of research suggests significant neuropsychological deficits in patients with OCD; executive dysfunction and nonverbal memory deficits have been reported consistently in OCD. These deficits persist despite controlling potential confounders such as comorbidity, severity of illness, and medications. Neuropsychological impairments are independent of illness severity, thus suggesting that the neuropsychological deficits are trait markers of the disease. In addition, these deficits are seen in first-degree relatives of individuals with OCD. These reports suggest that neuropsychological deficits are potential endophenotype markers in OCD. Neuropsychological studies in pediatric OCD are limited; they show impairments of small effect size across multiple domains but with doubtful clinical significance. Preliminary evidence shows that different symptom dimensions of OCD may have unique neuropsychological deficits suggestive of discrete but overlapping neuroanatomical regions for individual symptom dimensions. Overall, neuropsychological deficits further support the role of frontostriatal circuits in the neurobiology of OCD. In addition, emerging literature also suggests the important role of other areas, in particular parietal cortex. Preliminary evidence suggests the possible role of neuropsychological deficits to be markers of treatment response but needs to be examined in future. Longitudinal studies with examination of patients at different time points and examination of their potential utility as predictors of treatment response are needed in future.

Abstract
Personality disorders are a common comorbidity in obsessive-compulsive disorder (OCD). The effect of comorbidity on the symptom presentation, course, and treatment outcome of OCD is being discussed here. OCD and obsessive-compulsive personality disorder (OCPD) though similar in their symptom presentation, are distinct constructs. Schizotypal disorder, OCPD, and two or more comorbid personality disorders have been found to be consistently associated with a poor course of illness and treatment response. Further research is needed to determine treatment strategies to handle the personality pathology in OCD.

Abstract
INTRODUCTION Autistic Spectrum Disorder (ASD) is often comorbid with Obsessive Compulsive Disorder (OCD). But to what extent can obsessional symptoms in individuals with ASD be considered "genuinely" comorbid OCD - or are there other mechanisms that are related to ASD? Which mechanisms in OCD with and without ASD share common features? People with ASD have a cognitive profile characterized by "mindblindness"; the antecedent is often referred to in terms of not knowing how to perform or behave and this is the cause of discomfort. This raises the question whether individuals with ASD and comorbid OCD share the same cognitive elements of responsibility interpretation and the same fear of causing harm as individuals who merely have OCD. OBJECTIVE The aim of the present study is therefore to evaluate the extent of responsibility interpretation in individuals with OCD alone compared with people experiencing OCD in the context of ASD. METHODS Two instruments, the Responsibility Attitude Scale (RAS) and the Responsibility Interpretations Questionnaire (RIQ), were administered to three groups of participants: (i) individuals diagnosed with OCD (n = 32); (ii) individuals with ASD and OCD (n = 19); and (iii) non-clinical control participants (n = 23). RESULTS Results indicate significant differences in all measures of responsibility belief (interpretation of obsession and assumption of responsibility) between the OCD-only group and the two other groups. CONCLUSION The conclusion is that OCD in people with ASD is not as "genuine" as in people with only OCD, according to cognitive behavioral theory of OCD.

Abstract
OBJECTIVE The aim of this study is to investigate whether insight and mentalizing abilities are related to the severity of Obsessive Compulsive Disorder (OCD) in treatment resistant OCD. We look at the association between treatment resistance, insight, and mentalizing ability. METHODS The study was conducted with 71 OCD patients; 30 of them met the criteria for treatment resistant OCD, whereas the other 41 (57.7%) were labeled as responder group. All patients were assessed with the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS), Reading the Mind in the Eyes Test (RMET), Brown Assessment of Beliefs Scale (BABS), Mini International Neuropsychiatric Interview, Beck Depression Inventory, and Beck Anxiety Inventory. RESULTS The resistant group received higher depression and anxiety mean scores and had significantly longer illness duration. The RMET score was significantly higher for responders. The Y-BOCS insight score and the BABS score were significantly higher for the resistant group. BABS scores were negatively correlated with RMET total scores. RMET scores were found to be significant predictor of insight even when other potential factors were controlled for. RESULTS suggest that better mentalizing abilities may be a predictor of better treatment outcome in patients with OCD.

Abstract
OBJECTIVES To examine the psychometric characteristics of the Nepean Belief Scale (NBS), a short clinician-administered scale that assesses the characteristics and intensity of beliefs in obsessive-compulsive disorder (OCD). METHODS The NBS was administered by two clinicians to 27 subjects with OCD as part of a larger study that included a comprehensive assessment using the Yale-Brown Obsessive Compulsive Symptom Scale (Y-BOCS), the Overvalued Ideas Scale (OVIS) and the Symptom Checklist 90-Revised (SCL-90R). Test-retest reliability of the NBS was assessed by administering the scale 5 days after initial administration. RESULTS The 5-item NBS proved easy to use with an assessment time of less than 5 min. Its interrater reliability revealed 99.5% concordance, while the kappa for test-retest reliability was 0.98 (95% CI = 0.95-1.00). Cronbach alpha coefficient for internal consistency was 0.87. The NBS was found to have excellent convergent and discriminant validity. CONCLUSIONS Preliminary results suggest that the NBS could be a useful shorter alternative to the currently more widely used instruments for assessing beliefs such as the OVIS and the Brown Assessment of Belief Scale. The NBS has clear instructions and definitions, excellent interrater reliability and convergent validity, and it more accurately measures belief-related insight.

Abstract
BACKGROUND It is known that obsessive-compulsive disorder (OCD) patients with poor insight display more severe neuropsychological impairments than other patients with OCD. There are limited studies of OCD and theory of mind (ToM). AIM To investigate ToM skills in patients with OCD and the relationship between insight and ToM skills by comparing OCD patients with good and poor insight. METHODS Eighty patients with OCD and 80 healthy controls completed the structured clinical interview for DSM-IV axis I disorders, the Yale Brown Obsessive-Compulsive Scale, the Beck Anxiety and Beck Depression Inventories, and the Brown Assessment of Beliefs Scale. To assess ToM skills, first- and second-order false-belief tests, a hinting test, a faux pas test, a reading the mind in the eyes test, and a double-bluff test were administered. RESULTS Patients with OCD had poorer ToM abilities than healthy controls. All ToM scores were significantly lower in the poor insight group than in the good insight group (p < .001). A significant negative correlation was found between the BABS-total scores and all the ToM test mean scores (p < .05). CONCLUSIONS The finding of significantly lower ToM skills in OCD with poor insight than in OCD with good insight may contribute to the idea of OCD with poor insight being a subtype with different clinical and neuropsychological characteristics.

Abstract
BACKGROUND There are limited data on neurobiological correlates of poor insight in obsessive-compulsive disorder (OCD). This study explored whether specific changes occur in small-world network (SWN) properties in the brain functional network of OCD patients with poor insight. METHOD Resting-state electroencephalograms (EEGs) were recorded for 12 medication-free OCD patients with poor insight, 50 medication-free OCD patients with good insight, and 36 healthy controls. RESULTS Both of the OCD groups exhibited topological alterations in the brain functional network characterized by abnormal small-world parameters at the beta band. However, the alterations at the theta band only existed in the OCD patients with poor insight. LIMITATIONS A relatively small sample size. Subjects were naïve to medications and those with Axis I comorbidity were excluded, perhaps limiting generalizability. CONCLUSIONS Disrupted functional integrity at the beta bands of the brain functional network may be related to OCD, while disrupted functional integrity at the theta band may be associated with poor insight in OCD patients, thus this study might provide novel insight into our understanding of the pathophysiology of OCD.

Abstract
The presence of obsessive-compulsive symptoms (OCS) and obsessive-compulsive disorders (OCD) in schizophrenia is frequent, and a new clinical entity has been proposed for those who show the dual diagnosis: the schizo-obsessive disorder. This review scrutinizes the literature across the main academic databases, and provides an update on different aspects of schizo-obsessive spectrum disorders, which include schizophrenia, schizotypal personality disorder (SPD) with OCD, OCD with poor insight, schizophrenia with OCS, and schizophrenia with OCD (schizo-obsessive disorder). An epidemiological discussion on the discrepancies observed in the prevalence of OCS and OCD in schizophrenia across time is provided, followed by an overview of the main clinical and phenomenological features of the disorder in comparison to the primary conditions under a spectral perspective. An updated and comparative analysis of the main genetic, neurobiological, neurocognitive, and pharmacological treatment aspects for the schizo-obsessive spectrum is provided, and a discussion on endophenotypic markers is introduced in order to better understand its substrate. There is sufficient evidence in the literature to demonstrate the clinical relevance of the schizo-obsessive spectrum, although little is known about the neurobiology, genetics, and neurocognitive aspects of these groups. The pharmacological treatment of these patients is still challenging, and efforts to search for possible specific endophenotypic markers would open new avenues in the knowledge of schizo-obsessive spectrum.

Abstract
The appraisal model of obsessive-compulsive disorder (OCD) suggests that six key appraisal domains contribute to the aetiology and maintenance of OCD symptoms. An accumulating body of evidence supports this notion and suggests that modifying cognitive appraisals may be beneficial in reducing obsessive-compulsive symptomatology. This literature review first summarises the nature of OCD and its treatment, followed by a summary of the existing correlational and experimental research on the role of cognitive appraisal processes in OCD across both adult and paediatric samples. While correlational data provide some support for the relationship between cognitive appraisal domains and OCD symptoms, results are inconclusive, and experimental methods are warranted to determine the precise causal relationship between specific cognitive appraisal domains and OCD symptoms.

Resting-state functional connectivity between right anterior insula and right orbital frontal cortex correlate with insight level in obsessive-compulsive disorder. NEUROIMAGE-CLINICAL 2017; 15:1-7.

Abstract
Few studies have explored the neurobiological basis of insight level in obsessive-compulsive disorder (OCD), though the salience network (SN) has been implicated in insight deficits in schizophrenia. This study was then designed to investigate whether resting-state (rs) functional connectivity (FC) of SN was associated with insight level in OCD patients. We analyzed rs-functional magnetic resonance imaging (fMRI) data from 21 OCD patients with good insight (OCD-GI), 19 OCD patients with poor insight (OCD-PI), and 24 healthy controls (HCs). Seed-based whole-brain FC and ROI (region of interest)-wise connectivity analyses were performed with seeds/ROIs in the bilateral anterior insula (AI) and dorsal anterior cingulate cortex (dACC). The right AI-right medial orbital frontal cortex (mOFC) connectivity was found to be uniquely decreased in the OCD-PI group, and the value of this aberrant connectivity correlated with insight level in OCD patients. In addition, we found that the OCD-GI group had significantly increased right AI-left dACC connectivity within the SN, relative to HCs (overall trend for groups: OCD-GI > OCD-PI > HC). Our findings suggest that abnormal right AI-right mOFC FC may mediate insight deficits in OCD, perhaps due to impaired encoding and integration of self-evaluative information about OCD-related beliefs and behaviors. Our findings indicate a SN connectivity dissociation between OCD-GI and OCD-PI patients and support the notion of considering OCD-GI and OCD-PI as two distinct disorder subtypes. We examined the functional connectivity of SN in OCD-GI and OCD-PI. OCD-PI patients had decreased right AI-right mOFC connectivity. Right AI- right mOFC connectivity correlated with insight level in OCD. OCD-GI patients had elevated right AI-left dACC connectivity within SN. These results are helpful toward elucidating insight presentation in OCD.

Spontaneous neural activity in the right superior temporal gyrus and left middle temporal gyrus is associated with insight level in obsessive-compulsive disorder. J Affect Disord 2017; 207:203-211. [PMID: 27723545 DOI: 10.1016/j.jad.2016.08.027] [Citation(s) in RCA: 55] [Impact Index Per Article: 7.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/03/2016] [Revised: 08/15/2016] [Accepted: 08/24/2016] [Indexed: 12/09/2022]
Abstract
BACKGROUND Insight into illness is an important issue for psychiatry disorder. Although the existence of a poor insight subtype of obsessive-compulsive disorder (OCD) was recognized in the DSM-IV, and the insight level in OCD was specified further in DSM-V, the neural underpinnings of insight in OCD have been rarely explored. The present study was designed to bridge this research gap by using resting-state functional magnetic resonance imaging (fMRI). METHODS Spontaneous neural activity were examined in 19 OCD patients with good insight (OCD-GI), 18 OCD patients with poor insight (OCD-PI), and 25 healthy controls (HC) by analyzing the amplitude of low-frequency fluctuation (ALFF) in the resting state. Pearson correlation analysis was performed between regional ALFFs and insight levels among OCD patients. RESULTS OCD-GI and OCD-PI demonstrated overlapping and distinct brain alterations. Notably, compared with OCD-GI, tOCD-PI had reduced ALFF in left middle temporal gyrus (MTG) and right superior temporal gyrus (STG), as well as increased ALFF in right middle occipital gyrus. Further analysis revealed that ALFF values for the left MTG and right STG were correlated negatively with insight level in patients with OCD. LIMITATIONS Relatively small sample size and not all patients were un-medicated are our major limitations. CONCLUSIONS Spontaneous brain activity in left MTG and right STG may be neural underpinnings of insight in OCD. Our results suggest the great role of human temporal brain regions in understanding insight, and further underscore the importance of considering insight presentation in understanding the clinical heterogeneity of OCD.

Abstract
BACKGROUND Cognitive insight, a recently developed insight measure, refers to metacognitive processes of the re-evaluation and correction of distorted beliefs and misinterpretations. However, to the best of the authors' knowledge, no study has specifically examined cognitive insight, demographics, psychopathological variables, and distorted beliefs in OCD. AIM The aim of this research was to examine links between cognitive insight and demographics, clinical factors, and distorted beliefs among patients with OCD. METHOD Eighty-four consecutive outpatients with a diagnosis of OCD underwent a detailed clinical assessment for OCD, including the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS), Beck Cognitive Insight Scale (BCIS), Thought-Action Fusion Scale (TAFS), White Bear Thought Suppression Inventory, Metacognition Questioniarre-30 (MCQ-30), and a sociodemographic questionnaire. In addition, 82 control subjects matched for age, education, and gender were tested. RESULTS BCIS-self-certainty scores were all substantially higher in subjects with remitted and unremitted OCD than in healthy comparison subjects, while BCIS-composite scores were significantly lower in both patient groups than controls. Obsession and compulsion severity had significant effects on BCIS scores. In addition, it was found that the specific symptoms were linked to self-certainty scores. Self-reflectiveness and composite scores had positive correlations with the sub-scale scores of the MCQ-30, while the TAF-morality score was positively correlated with self-certainty scores. CONCLUSION The results demonstrated poor cognitive insight among remitted and unremitted OCD patients. In addition, the present study suggested significant associations between sociodemographic and clinical features and dysfunctional appraisals. Cognitive-behavioural techniques aimed at enhancing cognitive insight may be beneficial for patients with OCD, particularly patients who have prominent dysfunctional beliefs.

Abstract
Individuals with obsessive-compulsive disorder (OCD) may struggle with hostility and suspicious thinking, but this has not been the subject of much research. The purpose of this study is to examine the relationship between hostility, suspicious thinking, and OCD severity. Participants included 66 outpatients in treatment for OCD, 27 in treatment for other disorders, and 68 students (n=161). All completed the Inventory of Hostility and Suspicious Thinking (IHS), a measure of psychotic thinking/paranoia, the Obsessive Compulsive Inventory-Revised (OCI-R), the Beck Depression Inventory (BDI-II), and the Beck Anxiety Inventory (BAI). As expected, the IHS was significantly positively correlated with the BAI and BDI-II. Additionally, regression analyses revealed that individuals with OCD have higher levels of hostility than students. Hostility was also significantly positively associated with increased OCD severity. Hostility and suspicious thoughts are prominent in anxiety disorders in general, and thus necessitate continued research.

Abstract
This study investigated comorbidity and hoarding symptoms in a sample of African American adults with obsessive-compulsive disorder ( N = 75). For lifetime disorders, 87.9% of participants had at least one other comorbid condition. The most prevalent comorbidities were mood disorders (67.1%), anxiety disorders (51.4%), and substance abuse disorders (38.0%). There was low comorbidity with eating disorders, as only 4.1% had binge-eating disorder and none met criteria for anorexia or bulimia nervosa. In terms of gender differences, females were more likely to have posttraumatic stress disorder and males were more likely to have a comorbid alcohol use disorder. Over half of the participants had hoarding compulsions (56.0%) as indicated by the Yale-Brown Obsessive-Compulsive Scale. Individuals with hoarding compulsions were more likely to have comorbid anxiety-related disorders than those without, and experienced greater indecisiveness, pathological slowness, and doubting; they also had less education and earning power than those without these behaviors. African Americans with obsessive-compulsive disorder tend to have high rates of comorbid disorders, with patterns that resemble findings in non-Hispanic White populations.
