The COGINS: A New Measure of Cognitive Insight in Obsessive-Compulsive and Related Disorders.

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.

Is the road to burnout paved with perfectionism? The prevalence of obsessive-compulsive personality disorder in a clinical longitudinal sample of female patients with stress-related exhaustion.

OBJECTIVES: Few studies have investigated the relationship between stress-related mental health problems and obsessive-compulsive personality disorder (OCPD). Similarly, little research has focused on the moderating effect of OCPD on recovery in clinical patients with stress-related mental health problems. The general aim of this study was to investigate the prevalence of OCPD and the associations between OCPD and level of burnout, anxiety, and depression symptoms, during a 7-years follow-up in a clinical longitudinal sample of female patients with stress-related exhaustion. METHOD: The included patients (n = 84) were referred to a specialist outpatient clinic for patients with stress-related exhaustion between 2006 and 2011. Data was collected at the initial examination and during a 7-year treatment follow-up. RESULTS: OCPD was the most common personality disorder in the present clinical sample, with 40% of patients fulfilling the criteria. There was a significant association between OCPD and the degree of burnout symptoms as well as the degree of depression, both at baseline and during the 7-year follow-up. No significant association between OCPD and levels of anxiety was observed. CONCLUSION: The results support the hypothesis that there might be an association between OCPD and stress-related exhaustion, including preservation of symptoms over time. OCPD and its related traits, such as perfectionism, may be important factors to consider when constructing effective treatment and rehabilitation plans for these patients.

Clinical characteristics of probands with obsessive-compulsive disorder from simplex and multiplex families.

Genetic and non-genetic factors contribute to obsessive-compulsive disorder (OCD), with strong evidence of familial clustering. Genomic studies in psychiatry have used the concepts of families that are "simplex" (one affected) versus "multiplex" (multiple affected). Our study compares demographic and clinical data from OCD probands in simplex and multiplex families to uncover potential differences. We analyzed 994 OCD probands (501 multiplex, 493 simplex) from the Brazilian Research Consortium on Obsessive-Compulsive Spectrum Disorders (C-TOC). Clinicians administered the Structured Clinical Interview for DSM-IV (SCID-IV) to diagnose, Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) to assess severity, and Dimensional Yale-Brown Obsessive-Compulsive Scale (DY-BOCS) to assess symptom dimensionality. Demographics, clinical history, and family data were collected. Compared to simplex probands, multiplex probands had earlier onset, higher sexual/religious and hoarding dimensions severity, increased comorbidity with other obsessive-compulsive-related disorders (OCRD), and higher family history of psychiatric disorders. These comparisons provide the first insights into demographic and clinical differences between Latin American simplex and multiplex families with OCD. Distinct clinical patterns may suggest diverse genetic and environmental influences. Further research is needed to clarify these differences, which have implications for symptom monitoring and management.

Conceptualising compulsivity through network analysis: A two-sample study.

Compulsivity is a transdiagnostic construct crucial to understanding multiple psychiatric conditions and problematic repetitive behaviours. Despite being identified as a clinical- and research-relevant construct, there are limited insights into the internal conceptual structure of compulsivity. To provide a more nuanced understanding of compulsivity, the current study estimated the structure of compulsivity (indexed using the previously validated Cambridge-Chicago Compulsivity Trait Scale, CHI-T) among two large-scale and geographically distinct samples using the network estimation method. The samples consisted of a United Kingdom cohort (n = 122,346, 51.4% female, Mean age = 43.7, SD = 16.5, range = 9-86 years) and a South Africa cohort (n = 2674, 65.6% female, Mean age = 24.6, SD = 8.6, range = 18-65 years). Network community analysis demonstrated that compulsivity was constituted of three interrelated dimensions, namely: perfectionism, cognitive rigidity and reward drive. Further, 'Completion leads to soothing' and 'Difficulty moving from task to task' were identified as core (central nodes) to compulsivity. The dimensional structure and central nodes of compulsivity networks were consistent across the two samples. These findings facilitate the conceptualisation and measurement of compulsivity and may contribute to the early detection and treatment of compulsivity-related disorders.

Update on treatment studies for compulsive buying-shopping disorder: A systematic review.

Background and aims: Compulsive buying-shopping disorder (CBSD) is mentioned as an example of other specified impulse control disorders in the ICD-11 coding tool, highlighting its clinical relevance and need for treatment. The aim of the present work was to provide a systematic update on treatment studies for CBSD, with a particular focus on online CBSD. Method: The preregistered systematic review (PROSPERO, CRD42021257379) was performed in accordance with the PRISMA 2020 statement. A literature search was conducted using the PubMed, Scopus, Web of Science and PsycInfo databases. Original research published between January 2000 and December 2022 was included. Risk of reporting bias was evaluated with the CONSORT guideline for randomized controlled trials. Effect sizes for primary CBSD outcomes were calculated. Results: Thirteen studies were included (psychotherapy: 2 open, 4 waitlist control design; medication: 2 open, 3 placebo-controlled, 2 open-label phase followed by a double-blind discontinuation phase; participants treatment/control 349/149). None of the studies addressed online CBSD. Psychotherapy studies suggest that group cognitive-behavioral therapy is effective in reducing CBSD symptoms. Pharmacological studies with selective serotonin re-uptake inhibitors or topiramate did not indicate superiority over placebo. Predictors of treatment outcome were rarely examined, mechanisms of change were not studied at all. Risk of reporting bias was high in most studies. Discussion: Poor methodological and low quality of reporting of included studies reduce the reliability of conclusions. There is a lack of studies targeting online CBSD. More high-quality treatment research is needed with more emphasis on the CBSD subtype and mechanisms of change.

Online compulsive buying-shopping disorder and social networks-use disorder: More similarities than differences?

BACKGROUND: Studies in convenience, non-clinical samples of young adults suggest overlap between online compulsive buying-shopping disorder (OCBSD) and social-networks-use disorder (SNUD). Considering the dearth of research, this study investigated OCBSD and SNUD in clinical samples. METHODS: Women with either OCBSD (n = 37) or SNUD (n = 41) were compared regarding sociodemographic variables, use time of the first-choice application, OCBSD/SNUD severity, general internet use, impulsivity, materialism, perceived chronic stress and the frequency of viewing posts of influencers and the urge to visit shopping websites or social networks after viewing influencer posts. RESULTS: Women in the OCBSD group were older, more often employed, had less often a qualification for university entrance, indicated a lower daily use time of the first-choice application and higher materialistic values as compared to those in the SNUD group. No group differences emerged regarding general internet use, impulsivity and chronic stress. Regression models indicate that chronic stress predicted the symptom severity in the SNUD but not in the OCBSD group. The SNUD group reported a higher frequency of viewing influencer posts as compared to the OCBSD group. The urge for online shopping or using social networks after viewing influencer posts did not significantly differ between both groups. CONCLUSION: The findings suggest commonalities and distinct features of OCBSD and SNUD which require further investigation.

Comparison of clinicians' and researchers' ratings of proposed diagnostic criteria for compulsive buying-shopping disorder within a Delphi study.

Diagnostic criteria for compulsive buying shopping disorder were recently proposed based on a Delphi consensus study including 138 experts from 35 countries. The present study represents a secondary analysis of those data. To provide further support for the validity of expert responses in the Delphi study, the sample was retrospectively divided into clinician and researcher subgroups. The two groups were compared with respect to demographic variables, their importance ratings of clinical features, possible diagnostic criteria, differential diagnoses and specifiers of compulsive buying shopping disorder. Researchers reported less years of treating/assessing individuals with compulsive buying shopping disorder and stated that they have treated/assessed individuals with compulsive buying shopping disorder less often in the last 12 months than clinicians. Responses from the two groups concerning the importance ratings of possible diagnostic criteria of compulsive buying shopping disorder converged with only few minor differences with small to moderate group effects. However, even for those criteria, the consensus threshold (≥75% agreement with the proposed criterion) was reached in both groups. The lack of differences in the responses of the two groups indicates good validity for the proposed diagnostic criteria. Future research should address the clinical applicability and diagnostic validity of the criteria.

Assessing compulsive sexual behavior disorder: The development and international validation of the compulsive sexual behavior disorder-diagnostic inventory (CSBD-DI).

Background and aims: The World Health Organization's International Classification of Diseases (ICD-11) includes Compulsive Sexual Behavior Disorder (CSBD), a new diagnosis that is both controversial and groundbreaking, as it is the first diagnosis to codify a disorder related to excessive, compulsive, and out-of-control sexual behavior. The inclusion of this novel diagnosis demonstrates a clear need for valid assessments of this disorder that may be quickly administered in both clinical and research settings. Design: The present work details the development of the Compulsive Sexual Behavior Disorder Diagnostic Inventory (CSBD-DI) across seven samples, four languages, and five countries. Setting: In the first study, data were collected in community samples drawn from Malaysia (N = 375), the U.S. (N = 877), Hungary (N = 7,279), and Germany (N = 449). In the second study, data were collected from nationally representative samples in the U.S. (N = 1,601), Poland (N = 1,036), and Hungary (N = 473). Findings: Across both studies and all samples, results revealed strong psychometric qualities for the 7-item CSBD-DI, demonstrating evidence of validity via correlations with key behavioral indicators and longer measures of compulsive sexual behavior. Analyses from nationally representative samples revealed residual metric invariance across languages, scalar invariance across gender, strong evidence of validity, and utility in classifying individuals who self-identified as having problematic and excessive sexual behavior, as evidenced by ROC analyses revealing suitable cutoffs for a screening instrument. Conclusion: Collectively, these findings demonstrate the cross-cultural utility of the CSBD-DI as a novel measure for CSBD and provide a brief, easily administrable instrument for screening for this novel disorder.

The impact of obsessive-compulsive personality disorder in perfectionism.

OBJECTIVE: The construct of perfectionism has long been related to Obsessive-Compulsive Personality Disorder (OCPD), though research has not considered how OCPD could distinguish individuals with elevated perfectionism. The aim of this study was to evaluate clinical differences between those with and without OCPD in a sample of individuals with elevated perfectionism. METHODS: Seventy-four university students with elevated perfectionism completed a diagnostic assessment and several self-report measures of clinical characteristics and were randomly assigned to complete an exposure-based treatment for perfectionism or waitlist. Thirty-four (45.95%) participants met DSM-IV diagnostic criteria for OCPD. RESULTS: Compared to those without OCPD, individuals with OCPD had higher levels of general and specific domains of perfectionism and higher levels of social anxiety. OCPD diagnosis was also associated with higher rates of current anxiety disorder. Importantly, those with and without OCPD showed comparable benefits from treatment. CONCLUSIONS: This study provides novel evidence of the role of OCPD in perfectionism and demonstrates the efficacy of a perfectionism-oriented treatment in individuals with OCPD.Key pointsWe examined the role of obsessive-compulsive personality disorder (OCPD) in a high perfectionism sample.OCPD was associated with higher perfectionism and personal standards.OCPD was also associated with higher social anxiety and higher rates of current anxiety disorder.Those with and without OCPD had comparable responses to an exposure-based treatment for perfectionism.

Understanding guilt-related interpersonal dysfunction in obsessive-compulsive personality disorder through computational modeling of two social interaction tasks.

BACKGROUND: Obsessive-compulsive personality disorder (OCPD) is a high-prevalence personality disorder characterized by subtle but stable interpersonal dysfunction. There have been only limited studies addressing the behavioral patterns and cognitive features of OCPD in interpersonal contexts. The purpose of this study was to investigate how behaviors differ between OCPD individuals and healthy controls (HCs) in the context of guilt-related interpersonal responses. METHOD: A total of 113 participants were recruited, including 46 who were identified as having OCPD and 67 HCs. Guilt-related interpersonal responses were manipulated and measured with two social interactive tasks: the Guilt Aversion Task, to assess how anticipatory guilt motivates cooperation; and the Guilt Compensation Task, to assess how experienced guilt induces compensation behaviors. The guilt aversion model and Fehr-Schmidt inequity aversion model were adopted to analyze decision-making in the Guilt Aversion Task and the Guilt Compensation Task, respectively. RESULTS: Computational model-based results demonstrated that, compared with HCs, the OCPD group exhibited less guilt aversion when making cooperative decisions as well as less guilt-induced compensation after harming others. CONCLUSION: Our findings indicate that individuals with OCPD tend to be less affected by guilt than HCs. These impairments in guilt-related responses may prevent adjustments in behaviors toward compliance with social norms and thus result in interpersonal dysfunctions.

Mental fatigue in individuals with psychiatric disorders: a scoping review.

OBJECTIVE: The aim of this study was to complete a scoping review of the published literature describing the relationship between mental fatigue and various psychiatric disorders, to better understand its frequency and clinical impact, and to provide recommendations for future clinical research. METHODS: A scoping review using PubMed/MEDLINE, Cochrane and PsychArticles databases was conducted using the keywords 'mental fatigue', 'mental tiredness' or 'mental exhaustion', and completed in accordance with the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols Extension for Scoping Reviews 2018 checklist. RESULTS: We extracted 10 studies fulfilling our inclusion criteria from a total of 2937 publications. Mental fatigue was studied within mood disorders, anxiety disorders, obsessive compulsive disorder and obsessive-compulsive personality disorder. A commonly used tool to measure mental fatigue in these samples was the Multidimensional Fatigue Inventory-20. Specific cognitive factors (unhelpful beliefs about sleep, symptom-focussed rumination) and personality risk factors (harm avoidance, self-directedness, cooperativeness, persistence) were relevant to predicting mental fatigue symptoms and rates of mental fatigue may vary with gender and diagnosis. CONCLUSION: Research into mental fatigue in adult psychiatric sample was limited to a few psychiatric disorders and requires further investigation.Key pointsA commonly used tool to measure mental fatigue was the Multidimensional Fatigue Inventory-20. However, more research into the validity and reliability for illness specific instruments to measure mental fatigue in psychiatric population is required.Reduction of mental fatigue was associated with improvement on quality of life.Specific cognitive factors (unhelpful beliefs about sleep, symptom-focussed rumination) and personality risk factors (harm avoidance, self-directedness, cooperativeness, persistence) were relevant to predicting mental fatigue symptoms and rates of mental fatigue may vary with gender.Reviewed articles indicated that mental fatigue presence was associated with lower odds of OCD. In addition, the results suggested that mental fatigue symptoms were more common in individuals with OCPD rather than OCD.Research into mental fatigue in adult psychiatric sample was limited to a few psychiatric disorders and requires further investigation to prevent potential misattribution as mental fatigue symptoms overlap between different psychiatric disorders.

Mapping the future of interventional psychiatry for the obsessive-compulsive related disorders: A scoping review.

Body dysmorphic disorder (BDD), hoarding disorder (HD), skin-picking disorder (SPD), and hair-pulling disorder (HPD) are characterized by compulsive behaviours leading to distress and impairment. Current treatments attain only partial or non-response. Interventional psychiatric approaches may target specific regions of the brain for treatment. This scoping review maps the current literature and synthesizes key findings. Databases were searched up to June 27, 2022 for studies examining interventional psychiatric treatments for BDD, HD, SPD, and HPD, producing 910 results. Twenty were included; 16 were case reports, two were case series, and two were randomized controlled trials. Studies reported on electroconvulsive therapy (ECT) (n=7), deep brain stimulation (DBS) (n=1), and intermittent theta-burst stimulation repetitive transcranial magnetic stimulation (rTMS) (n=1) for BDD; rTMS (n=1) and transcranial direct current stimulation (n=1) for HD; gamma knife capsulotomy (n=1) and rTMS (n=1) for SPD; and rTMS (n=2) and ECT (n=1) for HPD. Four studies reported on DBS for other indications complicated by SPD or HPD. The current literature consists mainly of case reports. Future studies should be randomized, controlled, adequately powered and blinded, examining rTMS localized to the anatomical targets for each disorder. Presently, the mainstay of treatment remains disorder-specific psychotherapy with limited evidence for medications.

Another failure of the latent disease model? The case of compulsive sexual behavior disorder •.

Recent debates have evolved regarding the classification/conceptualization of compulsive sexual behavior disorder (CSBD). Conclusions regarding an agreed upon CSBD model are hindered by reliance on the latent disease model. Competing biological-based frameworks are moving forward to replace latent disease classification more broadly but have been met with limited success. We suggest that CSBD researchers move towards developing dimensional, transtheoretical, process-based models. We further suggest additional research, particularly mixed methods and longitudinal studies. Finally, we request that federal funding bodies take a more active role in supporting CSBD research.

Subjective assessments of research domain criteria constructs in addiction and compulsive disorders: a scoping review protocol.

INTRODUCTION: Obsessive-compulsive and related disorders (OCRDs) and disorders due to addictive behaviours (DABs) are prevalent conditions that share behavioural and neurobiological characteristics. The Research Domain Criteria lists a series of constructs whose dysfunctions may be present in both groups of disorders. The present study will describe the research protocol of a scoping review of the literature on self-report scales and questionnaires that tap dysfunctional constructs that underlie OCRDs and DABs. METHODS AND ANALYSIS: This protocol outlines a scoping review on self-report tools and questionnaires that assess OCRDs and DABs-related constructs. The scoping review will select sources in MEDLINE, EMBASE, PsychINFO and Web of Science databases. Inclusion and exclusion criteria will be designed according to the Population, Concept, Context, Types of source framework. Two reviewers will screen independently titles, abstracts and full texts to determine the eligibility of articles. A methodological framework including six stages steps ((1) identifying a research question; (2) identifying relevant studies; (3) study selection; (4) charting the data; (5) collating, summarising and reporting the result) will be used, and the findings will be reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews checklist. Information extracted will be collated, and quantitative results will be presented using descriptive statistics such as percentages, tables, charts and flow diagrams as appropriate. ETHICS AND DISSEMINATION: Ethical approval for conducting this scoping review is not required, as this study will involve secondary analysis of existing literature. The researchers will disseminate the study results via conference presentations and publication in a peer-reviewed journal. SCOPING REVIEW PROTOCOL REGISTRATION: DOI 10.17605/OSF.IO/UJ7G5.

The alternative model of personality disorder is inadequate for capturing obsessive-compulsive personality disorder.

The alternative model of personality disorder (AMPD) included in Section III of the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) reconceptualized personality pathology in terms of pathological traits and impairments in functioning. For example, the construct of obsessive-compulsive personality disorder (OCPD) was reconceptualized via the traits of rigid perfectionism as well as at least 2 of perseveration, intimacy avoidance, and restricted affectivity. We review the literature to summarize how effectively the legacy construct of OCPD is captured by the AMPD. We conclude that although the trait of rigid perfectionism is highly related to scores on OCPD measures, the AMPD as a whole fails to adequately account for the broader features of the legacy OCPD construct. Specifically, the AMPD trait model lacks a number of traits, such as workaholism, excessive deliberation, and moral scrupulousness, which are necessary for a fulsome dimensional trait system. These limitations in the inclusion of important traits stem from the AMPD's development process that left out crucial content. We outline how the AMPD could be improved in its ability to account for problems of overcontrolled behavior. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

Contradicting classification, nomenclature, and diagnostic criteria of Compulsive Sexual Behavior Disorder (CSBD) and future directions •.

Building on the conclusions of the debate papers by Gola et al. (2022) and Sassover and Weinstein (2022), the present commentary further addressed the contradictions between the current classification, nomenclature, and diagnostic criteria of Compulsive Sexual Behavior Disorder (CSBD) with elaborating on the potential roles impulsivity and compulsivity may play in CSBD, and how these characteristics may relate to addictive behaviors in particular. Moreover, it briefly discussed how the classification of CSBD might impact research and clinical practice and proposed potential future research directions that may help to reach a consensus on the classification and core symptoms of CSBD.

Where to put Compulsive Sexual Behavior Disorder (CSBD)? Phenomenology matters •.

In this commentary paper, it is discussed if Compulsive Sexual Behavior Disorder (CSBD) is best categorized as an Impulse Control Disorder, an Obsessive-Compulsive Disorder or in light of the overlap of characteristics with both Gaming and Gambling Disorder as an addictive behavior. The overlapping features are: loss of control over the respective excessive behavior, giving increasing priority to the excessive behavior under investigation and upholding such a behavior despite negative consequences. Besides empirical evidence regarding underlying mechanisms, phenomenology also plays an important role to correctly classify CSBD. The phenomenological aspects of CSBD clearly speak in favor of classifying CSBD under the umbrella of addictive behaviors.

Introduction to the Special Issue: Conceptualization, Assessment, and Treatment of Obsessive-Compulsive Disorder and Co-Occurring Conditions.

Obsessive-compulsive disorder (OCD) has a lifetime prevalence of 1%-2% and typically presents as a chronic condition with significant functional impairment. Comorbidity with OCD is the norm, with 90% of individuals with OCD also meeting diagnostic criteria for a co-occurring condition. Co-occurring conditions can complicate the conceptualization, assessment, and treatment of OCD, such as by intensifying existing symptoms, obscuring differential diagnosis of phenotypically and functionally similar symptoms, and interfering with cognitive behavioral treatment. This two-part special issue reviews extant literature and provides expert advice on conceptualizing, assessing, treating, and researching OCD with co-occurring conditions of depression, posttraumatic stress disorder, eating disorders, schizophrenia, hoarding disorder, panic disorder, obsessive-compulsive personality disorder, and illness anxiety disorder.

Efficacy and tolerability of pharmacotherapy for obsessive-compulsive personality disorder: a systematic review of randomized controlled trials.

INTRODUCTION: Although obsessive-compulsive personality disorder (OCPD) is one of the most prevalent personality disorders, it is one of the least studied. There is debate as to whether pharmacotherapy is efficacious for OCPD. We aimed to systematically evaluate the efficacy and tolerability of pharmacotherapy for OCPD. AREAS COVERED: This systematic review found two randomized controlled trials investigating pharmacotherapy of OCPD. In a study of major depression (n = 308) with comorbid OCPD (n = 71), citalopram was more effective for OCPD than sertraline with fewer drop-outs from treatment. In a small study of OCPD (n = 24), fluvoxamine was more effective than placebo, and there was a low drop-out rate. Risk of bias and quality assessment of these studies was not possible, and findings have very low levels of certainty. EXPERT OPINION: Two studies provide preliminary evidence in support of citalopram and fluvoxamine for OCPD. Further randomized controlled trials are required before firm conclusions can be drawn regarding efficacy of pharmacotherapy for OCPD.

Motherhood and Treatment Outcome in Female Patients with Compulsive Buying-Shopping Disorder.

Motherhood has been proposed as an internal facilitating factor for the recovery of women with mental disorders. However, at the same time, there are significant barriers that may be interfering with the access and adherence to treatment for these women. The present longitudinal study aimed to deepen the sociodemographic and clinical profile of women with children and compulsive buying-shopping disorder (CBSD), and to explore the association between motherhood and response to treatment. The total sample included 77 women with a diagnosis of CBSD (n = 49 mothers) who received cognitive behavioral therapy (CBT) for 12 weeks. No association between psychopathology and motherhood was observed. The group of mothers reported an older age of onset of the CBSD, a lower amount of money spent per compulsive-buying episode, and a higher likelihood of family support for the CBSD. Moreover, this group showed lower risk of relapse. The findings support the theoretical proposal that considers motherhood as an internal facilitating factor for recovery and treatment adherence of mothers with addictions.
