Exposure therapy tailored to inhibitory learning principles in a naturalistic setting: an open pilot trial in obsessive-compulsive outpatient care.

Inhibitory learning (IL) theory offers promising therapeutic strategies. However, more evidence is needed, especially regarding OCD treatment in routine care. The present pilot study investigated the positive and negative effects of IL-focused cognitive-behavioral therapy (CBT) in a university outpatient setting. A total of N = 21 patients (57.14% male, mean age 31.14, SD = 12.39 years) passed through manualized therapy delivered by licensed psychotherapists. Between the first and 20th IL-focused CBT session, obsessive-compulsive symptoms (Obsessive Compulsive Inventory-Revised, d = 3.71), obsessive beliefs (Obsessive-Beliefs Questionnaire, d = 1.17), depressive symptoms (Beck Depression Inventory, d = 3.49), and overall psychological distress (Global Severity Index, d = 3.40) decreased significantly (all ps < 0.01). However, individual patients reported some negative effects of therapy. The results underline the value of thorough investigations of novel therapeutic interventions in naturalistic settings.

Effects of obsessive beliefs and anxiety on sexual function in HPV-positive men.

Our study aimed to investigate the effects of anxiety and obsessive beliefs on sexual function in men with human papillomavirus (HPV) and healthy men. Ninety HPV-positive men (mean age=32.26 ± 6.63 years) from the Urology Outpatient Clinic and 75 healthy men (mean age=33.51 ± 5.67 years) who worked in the hospital were assessed using the International Index of Erectile Function-15 (IIEF-15), Obsessive Beliefs Questionnaire-44 (OBQ), and State-Trait Anxiety Inventory (STAI) in 2023. The mean IIEF-15 scores of the patients with HPV and healthy individuals were 24.59 ± 6.14 vs. 23.16 ± 6.23 for the IIEF-erectile function; 8.30 ± 2.34 vs. 7.79 ± 1.77 for the IIEF-orgasmic function; 7.40 ± 1.73 vs. 7.23 ± 1.53 for the IIEF-sexual desire; 11.30 ± 3.38 vs. 11 ± 3.10 for the IIEF-intercourse satisfaction; and 7.62 ± 2.18 vs. 7.53 ± 2.02 for the IIEF-overall satisfaction (p > 0.05 for all). However, the mean OBQ and STAI scores of patients with HPV and healthy individuals were 46.66 ± 16.06 vs. 36.44 ± 19.25 for the OBQ-inflated responsibility/overestimation of threat (OBQ-RT); 45.91 ± 17.31 vs. 36.53 ± 19.08 for the OBQ-perfectionism/intolerance of uncertainty (OBQ-PU); 28.04 ± 12.31 vs. 23.80 ± 11.74 for the OBQ-importance of thought/control thoughts (OBQ-IC); 37.58 ± 12.06 vs. 33.59 ± 11.09 for the STAI-state anxiety (p < 0.05 for all); and 32.83 ± 8.34 vs. 33.44 ± 11.05 for the STAI-trait anxiety (p = 0.689). Our results showed that the STAI-state anxiety (β = -0.37; β = -0.32; and β = -0.43, respectively) and OBQ-IC (β = -0.57; β = -0.43; and β = -0.48, respectively) scores were the main predictors of the IIEF-erectile function, IIEF-orgasmic function, and IIEF-overall satisfaction scores in the HPV-positive group. The OBQ-RT (β = 0.46), OBQ-PU (β = -0.51) and STAI-state anxiety (β = -0.56) scores were unique predictors of the IIEF-sexual desire score, and the OBQ-RT (β = 0.41), OBQ-PU (β = -0.42), and OBQ-IC (β = -0.43) scores were the main predictors of the IIEF-intercourse satisfaction score in the HPV-positive group. However, regression models for the IIEF-15 subscales for the control group were not significant (p ˃ 0.05). Understanding the role of obsessive beliefs and anxiety in sexual dysfunction among HPV-positive men might be important for developing psychotherapeutic interventions.

Psychometric Properties of Thai Version of Obsessive Belief Questionnaire (OBQ-T)

Background: Obsessive Beliefs Questionnaire (OBQ) is a valid measure for assessing obsessional beliefs, which are the main symptoms of obsessive-compulsive disorder (OCD). It is translated and assessed psychometric properties in many languages, however, no valid questionnaire for assessing the beliefs related to OCD is established in Thailand. Objective: To assess the psychometric properties of the Thai version of the Obsessive Belief Questionnaire (OBQ-T). Materials and Methods: Participants include ninety-two OCD patients who were duly informed of the details of the present study. Written consent was obtained. The Obsessive Beliefs Questionnaire-44 (OBQ-44) was translated into Thai (OBQ-T) after receiving permission. Data regarding the characteristics of the participants, the OBQ-T, the Thai self-report version of the Yale-Brown Obsessive-Compulsive Scale-Second Edition (Y-BOCSII-SR-T) severity scale, the Thai Florida Obsessive Compulsive Inventory (FOCI-T), the Patient Health Questionnaire (PHQ-9), and the Pictorial Thai Quality of Life (PTQL), were collected and analyzed. Psychometric properties of the OBQ-T were tested. Results: The OBQ-T has excellent reliability with a Cronbach’s coefficient of 0.945. It has a positive correlation with the Y-BOCS II-SR-T severity scale and the FOCI, which indicates the concurrent validity of the OBQ-T. The content validity index shows acceptable content validity. The confirmatory factor analysis (CFA) and the exploratory factor analysis (EFA) were examined, and the three-factor model is most similar to the original OBQ-44, which is composed of three factors reflecting responsibility and threat estimation, perfectionism and intolerance for uncertainty, and importance and control of thought. Conclusion: The OBQ-T has an acceptable reliability and validity for the measurement of beliefs and appraisals, which are related to the pathogenesis of obsessions.

Profiling orthorexia nervosa in young adults: the role of obsessive behaviour, perfectionism, and self-esteem

BackgroundOrthorexia nervosa (ON) is a relatively new potential eating disorder characterized by an intense fixation on one’s eating habits and the imposition of rigid and inflexible rules on oneself. Psychological factors such as obsessive–compulsive tendencies, perfectionism and self-esteem may interact in complex ways and contribute to the development and maintenance of ON.MethodsThis cross-sectional study included 977 participants from Italy, Lebanon, and Poland. Participants completed a questionnaire consisting of socio-demographic information, the Eating Habits Questionnaire, Obsessive–Compulsive Inventory, Obsessive Beliefs Questionnaire-44, Multidimensional Perfectionism Scale, and Rosenberg Self-Esteem Scale. Cluster analysis was used to identify subgroups of individuals with common psychological characteristics associated with ON.ResultsThree distinct clusters were identified based on their levels of obsession-compulsive beliefs, perfectionism, and self-esteem. The first group, labeled “High Self-Mastery,” consisted of 37.0% of participants and exhibited low levels of obsession-compulsion, obsessive beliefs, and perfectionism, but high self-esteem. The second group, “Moderate Self-Mastery,” comprised 39.5% of participants and had moderate levels of these traits. The third group, “Low Self-Mastery,” consisted of 23.6% of participants and exhibited the highest levels of obsession-compulsion, obsessive beliefs, and perfectionism, but the lowest self-esteem. Additionally, a multivariable analysis revealed that being Lebanese (Beta = 3.39) and belonging to the last cluster (Beta = 4.53) were significantly associated with higher ON tendencies.ConclusionOur findings show that individuals with low self-mastery, characterized by low self-esteem and high levels of obsessive perfectionism, are more likely to exhibit ON tendencies. This study emphasizes the need to have a comprehensive understanding of how cultural and psychological factors interact in the development of eating disorders.

The Relationship Between Childhood Traumatic Experiences and Obsessive Beliefs in Alcohol Use Disorder

Objective: Based on the pathophysiological similarities between alcohol use disorder (AUD) and obsessive compulsive spectrum disorders, as well as the close association between traumatic experiences and addiction, the goal of this study was to assess the relationship between obsessive beliefs and childhood traumas in patients with alcohol use disorder by comparing them with the control group.&#x0D; Material and Method: The data of 60 AUD cases who applied to the Alcohol and Substance Treatment Center (AMATEM) outpatient clinic consecutively and 56 healthy control groups were evaluated. Structured Clinical Interview for DSM-5 (SCID-5), Obsessive Beliefs Questionnaire (OBS), Childhood Trauma Questionnaire (CTS), Hamilton Anxiety Inventory (HAM-A), and Hamilton Depression Inventory (HAM-D) were applied to both groups. The Addiction Profile Index, which evaluates the severity of addiction, was applied to the patient group. Data were evaluated with SPPS 22.&#x0D; Results: Obsessive beliefs, traumatic experiences, depression and anxiety scores were found to be significantly higher in AUD cases than in the control group. No significant relationship was found between traumatic experiences and obsessive beliefs. The most important predictors of obsessive beliefs were found to be anxiety and depression scores.&#x0D; Conclusion: The current study is valuable because it is the first study to evaluate the relationship between obsessive beliefs and childhood traumas in alcohol use disorder patients. Further analyzes in a larger sample in this area will be helpful in identifying risk factors and creating preventive interventions for AUD, a disorder that is difficult to treat and recurs.

Investigation of Thought Control and Obsessive Beliefs in Generalised Anxiety Disorder and Panic Disorder

Aims: Obsessive beliefs and thought control are often thought to be associated with Obsessive Compulsive Disorder. However, the relationship with anxiety disorders has recently been investigated in the literature. In this study, Obsessive Beliefs and Thought Control levels in patients diagnosed with Generalised Anxiety Disorder and Panic Disorder were investigated. It is aimed to contribute to the literature on the cognitive aspects of anxiety disorders.&#x0D; Material and Method: According to DSM 5 diagnostic criteria, 71 patients diagnosed with Generalised Anxiety Disorder, 63 patients diagnosed with Panic Disorder and 63 healthy controls were included in the study. The participants were applied the Thought Control Questionnaire and Obsessive Beliefs Questionnaire. In addition, Beck Anxiety Scale was applied to patients diagnosed with Generalised Anxiety Disorder and Panic Agoraphobia Scale was applied to patients diagnosed with Panic Disorder.&#x0D; Results: A statistically significant difference was found between the groups in Distraction (F=11.383; p=

Obsessive-Compulsive Symptom Dimensions and Their Relationships with Obsessive Beliefs: A Structural Equation Modeling Analysis.

Dysfunctional beliefs are central in the development and maintenance of obsessive-compulsive disorder (OCD) as well as its treatment. Yet, research suggests that not all dysfunctional beliefs are equally important for each of the symptom dimensions of OCD. However, results are inconsistent in that studies contradict each other regarding the associations between specific symptom dimensions and belief domains. The aim of the present study was to clarify which belief domain is specifically associated with which OCD symptom dimension. Results could help to tailor treatments more specifically to the patient's OCD symptom dimension. In- and outpatients with OCD (N = 328; 43.6% male and 56.4% female) filled out questionnaires on symptom dimensions of OCD (Obsessive-Compulsive Inventory Revised) and dysfunctional beliefs (Obsessive Beliefs Questionnaire). A structural equation model analysis was conducted to identify the associations between dysfunctional beliefs and symptom dimensions. Our results showed that perfectionism/intolerance of uncertainty was associated with hoarding and symmetry/ordering, (2) overestimation of threat/inflated responsibility was associated with checking compulsions, and (3) importance of thoughts/control of thoughts was associated with obsessing. These results were largely supported by a backward selection. Our results demonstrated associations of specific dysfunctional beliefs and specific OCD symptom dimensions. However, future studies are necessary to replicate these findings with other measures (e.g., clinician ratings).

The Mediating Role of Dark Triad Personality Traits in the Relationship Between Childhood Traumas and Obsessive Beliefs

This study aims to investigate the relationship between childhood traumas, dark triad personality traits, and obsessive beliefs. Personal Information Form, Childhood Trauma Questionnaire, Short Dark Triad Scale, and Obsessive Beliefs Questionnaire were used to collect data in the study. A total of 480 volunteers, of which 306 were female and 174 were male, participated in the study. Pearson Correlation Analysis, independent samples t-test, and Parallel Multiple Mediator Variable analysis were used for the analysis of the obtained data. The correlation analysis results showed that childhood traumas were significantly and positively associated with both dark triad personality traits and obsessive beliefs. Male participants' psychopathic personality traits mean scores were found to be significantly higher than those of females. Mediation analysis results show that the psychopathic personality traits had a mediating effect on the relationship between the physical and emotional neglect and abuse sub-dimensions of childhood traumas and obsessive beliefs. The findings were discussed vis-à-vis the available relevant literature and suggestions were presented.

Predicting Symptoms of Obsessive-Compulsive Disorder Based on Cognitive Beliefs and Mindfulness in a Non-clinical Population

Objective: Obsessive-compulsive disorder (OCD) is one of the most common, controversial, and challenging disorders among the various psychological disorders. This research aimed to predict symptoms of OCD based on cognitive beliefs and mindfulness in a non-clinical population. Materials and Methods: The research design was descriptive-correlational. The statistical population comprised all students from universities in the city of Tabriz. A sample of 500 individuals was selected through convenience sampling. Research tools included the Revised Obsessive-Compulsive Questionnaire, Mindfulness Scale, and Obsessive Beliefs Questionnaire. Pearson correlation coefficient and multiple regression were used to analyze the research hypotheses. Data analysis was performed using SPSS software, version 25. Findings: Statistical analysis results showed that the combination of cognitive beliefs and mindfulness could predict symptoms of washing, obsessive symptoms, hoarding symptoms, ordering symptoms, checking symptoms, and neutralizing symptoms of OCD (p &lt; 0.05). Conclusion: Based on the results, it can be inferred that professionals can utilize the potential of the variables studied in the areas of diagnosis and clinical interventions for OCD.

Saving Cognitions Inventory: Turkish Form, Validity and Reliability Study

Saving Cognitions Inventory (SCI) was developed by Steketee and her colleagues (2003) to evaluate cognitive processes of Hoarding Disorder. These cognitive processes are emphasized as major contributors to the etiology of the Hoarding Disorder. The aim of the study was to adapt Turkish version of SCI and evaluate its validity and reliability. The study consisted of two separate adult sample groups including a total of 719 people whose age ranged 18-59. The first sample consisted of 252 participants with a mean age of 21.60 (SD = 4.07) and the second sample consisted of 467 participants with a mean age of 24.31 (SD = 6.51) Participants were asked to fill a battery of questionnaires including Melbourne Decision Making Questionnaire, The Obsessive Belief Questionnaire – 44, Saving Inventory – Revised and The Object Attachment Questionnaire. The factor structure was examined by exploratory factor analysis and the results supported the four-factor structure including emotional attachment, memory, control and responsibility domains. Four items were distributed in a different factor structure than the original form. These items were remained under the new factor loadings and the model was tested with a confirmatory factor analysis. As a result, the validity indices of the Turkish form were found to be sufficient levels. The internal consistency coefficient Cronbach’s Alpha was calculated as .91 and split-half reliability was calculated as .84. Test-retest correlation coefficient was found to be .77. The reliability coefficients of the inventory demonstrated comparable values to its original form. Furthermore, promoting concurrent validity total and sub-total scores of saving cognitions inventory were positively correlated with obsessive beliefs, object attachment and saving behavior. In the current study, SCI Turkish form, was evaluated to be a valid and reliable psychometric tool.

Virtual reality exposure and response prevention in the treatment of obsessive-compulsive disorder in patients with contamination subtype in comparison with in vivo exposure therapy: a randomized clinical controlled trial

BackgroundObsessive-Compulsive Disorder (OCD) is characterized by disturbing and unwanted thoughts as well as repetitive and time-consuming behaviors that interfere with performance. Cognitive Behavior Therapy (CBT) has shown to have beneficial effects on reducing OCD symptoms as the first line of treatment. Moreover, Virtual Reality (VR) has been a more feasible and accessible intervention for OCD in recent years. Regarding the point, the objective of this study was to evaluate the effectiveness of virtual reality exposure and response prevention (VRERP) in the treatment of the OCD contamination subtype.MethodsA total number of 36 adults with OCD-contamination subtype were registered and randomly assigned to the intervention and control groups. The intervention group received a 60-min CBT including a “contaminated” virtual environment while the control group received CBT as a standardized treatment. Out of these, 29 patients completed the treatment in 12 weekly sessions. The patients completed the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS), Beck Depression Inventory-II (BDI-II), Beck Anxiety Inventory (BAI), Obsessive Beliefs Questionnaire-44(OBQ-44), and World Health Organization Disability Assessment Scale-2 (WHODAS-2) at week 0, week 12 and after 3 months follow-up.ResultsBased on the results of the repeated measure analysis of variances, the total score of obsession and compulsion subscales of Y-BOCS significantly decreased as a primary outcome in the intervention group (F = 60.97, P < 0.001, partial eta squared = 0.82; F = 20.46, P < 0.001, partial eta squared = 0.61; F = 29.57, P < 0.001, partial eta squared = 0.69; respectively). The total score of BDI-II and BAI was reduced in both groups but there was no significant difference between them (BDI-II: F = 0.54, P = 0.47, partial eta squared = 0.02; BAI: F = 3.12, P = 0.06, partial eta squared = 0.19). However, there was a significant difference in the OBQ-44 (F = 16.78, P < 0.001, partial eta squared = 0.56) and the total WHODAS-2 score between the groups (F = 14.64, P < 0.001, partial eta squared = 0.53).ConclusionsThis study demonstrated the effectiveness of VRERP in the treatment of the OCD-contamination subtype. Therefore, VRERP can be used in CBT as an alternative exposure tool.Trial registrationIranian Registry of Clinical Trials, IRCT ID: IRCT20210214050353N1, Registered on 16/10/2021.

Use of structural modeling to explain high school students obsessive beliefs based on symptoms of stress, anxiety, and depression, metacognitive beliefs, and self-esteem: The mediating role of inferential confusion

Introduction: Thoughts, impulses, or images that are distressing and intrusive characterize obsessive-compulsive disorder. On the other hand, obsessive beliefs are important in turning intrusive thoughts into obsessive thoughts. Aim: This study aimed to present a structural model to explain obsessive beliefs among high school students, based on the symptoms of stress, anxiety, and depression, metacognitive beliefs, and self-esteem, considering the mediating role of inferential confusion. Method: In this correlational study, the statistical population included all secondary high school students in Aligudarz, Lorestan Province, Iran, during the 2020-2021 academic years. A total of 300 individuals were selected using cluster sampling. Data were collected using the Obsessive Beliefs Questionnaire (OBQ-44), Depression, Anxiety, and Stress Scale (DASS-21), Metacognitions questionnaire-30 (MCQ-30), Inferential Confusion Questionnaire-Expanded Version (ICQ-EV), and Rosenberg Self-Esteem Scale (RSES). Data analysis was performed using structural equation modeling in SPSS-20 and AMOS-24. Results: The goodness of fit indices of the measurements model (2/df=3.12, RMSEA=0.084) supported the good fitness of the model. Also, the goodness of fit indices of the structural model (2/df=2.24, RMSEA=0.064) indicated the good fit of the model for the collected data. Conclusion: Based on the results, metacognitive beliefs, symptoms of stress, depression, and anxiety, and self-esteem are among factors affecting obsessive beliefs; inferential confusion plays a mediating role in their association with obsessive beliefs. Therefore, elimination or moderation of contributing factors is essential for correcting obsessive-compulsive beliefs.

Are there differences in oxidative stress and inflammatory processes between the autogenous and reactive subtypes of obsessive-compulsive disorder? A controlled cross-sectional study.

Objective:To date, no study has investigated whether autogenous and reactive obsessive-compulsive disorder (OCD) types are different entities in terms of oxidative stress and inflammatory processes. The aim of this study is to compare them in terms of these features.Methods:The study was conducted in subjects with reactive OCD (n=19), autogenous OCD (n=14), and a control group (n=17). All participants were non-smokers. Sociodemographic data were collected and the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS), Beck Anxiety Inventory (BAI), Beck Depression Inventory (BDI), Obsessive Beliefs Questionnaire (OBQ), and Overvalued Ideas Scale (OVIS) were administered. High-sensitivity C-reactive protein (hs-CRP), interleukin-6 (IL-6), interleukin-10 (IL-10), paraoxonase (PON1), total oxidant status (TOS), and total antioxidant status (TAS) were measured.Results:There were no significant differences in TAS, TOS, or oxidative stress index (OSI) between the OCD and control groups. PON1 and hs-CRP levels were higher in the OCD group, whereas IL-6 and IL-10 levels were lower. Comparison across the three groups revealed no differences in TAS, TOS, OSI, or PON1 levels; however, hs-CRP was significantly higher while IL-6 and IL-10 were significantly lower in the reactive group compared to controls.Conclusion:Our results show that, although inflammatory processes may play a role in OCD, the autogenous and reactive subtypes do not differ from each other in these respects. The classification of OCD into autogenous and reactive subtypes should be reevaluated.

Psychometric properties of persian version of Fear of Self Questionnaire related Obsessive Compulsive Disorder

Introduction: The cognitive aspect of obsession involves the evaluation of oneself, which is often accompanied by a fear of what one is -or can be. Aim: The aim of this study was to investigate the psychometric properties of the Fear of Self Questionnaire, which measures the level of this fear in the context of obsessive-compulsive disorder. Method: The present study was a descriptive study and its statistical population included all students of Shiraz University in the academic year 2020-2021. The sample of the present study also included 360 students who were participated in this research by answering the online link of questions. In addition to the Persian version of the Fear of Self Questionnaire, other research tools were included the Obsessive Beliefs Questionnaire (OBQ-42), the Maudsley Obsessional Compulsive inventory (MOCI), the Self-Ambivalence Measure (SAM), and the Depression, Anxiety, and Stress Scale (DASS-21). Data analysis was conducted by confirmatory factor analysis, convergent validity, Cronbach's alpha coefficient, and test-retest reliability coefficient in SPSS-24 and AMOS-22 software. Results: The results of factor analysis confirmed the one-factor structure in the Persian version of the Fear of Self Questionnaire. Cronbach's alpha and test-retest coefficients were 0.94 and 0.86, respectively, that shows the internal consistency and optimal reliability of this questionnaire. In addition, the correlation between the scores of the Persian version of the questionnaire and other research tools ranged from 0.49 to 0.81, which has confirmed its convergent validity. Conclusion: Considering the psychometric properties of the Persian version of the Fear of Self Questionnaire, its usage can be recommended in research related to the symptoms and various dimensions of obsession.

Obsessive Beliefs and Clinical Features in Patients with Comorbid Obsessive-Compulsive Disorder and Attention-Deficit/Hyperactivity Disorder.

Obsessive-compulsive disorder (OCD) and attention-deficit/hyperactivity disorder (ADHD) are two common neuropsychiatric conditions. Obsessive beliefs, comprising the importance and control of intrusive thoughts, inflated sense of responsibility for harm, overestimations of threat, perfectionism, and intolerance of uncertainty have been suggested to influence OCD symptomatology. Although OCD patients with ADHD have been reported to have different clinical characteristics compared to patients with OCD without ADHD, it has not been previously investigated whether OCD patients with and without ADHD differ in terms of obsessive beliefs. The aim of this study was to compare the obsessive beliefs and obsessive-compulsive symptoms of OCD patients with and without ADHD. The study included a total of 197 OCD patients who were assessed with the sociodemographic data form, Wender Utah Rating Scale, Turgay's Adult ADD/ADHD Diagnosis and Evaluation Scale, The Adult ADHD Self-Report Scale, Obsessive Beliefs Questionnaire-44 (OBQ-44), Yale-Brown Obsessions and Compulsions Scale, Dimensional Obsessive-Compulsive Scale (DOCS), Beck Depression Inventory (BDI), and Beck Anxiety Inventory (BAI). The scores of all subscales of OBQ-44, the responsibility, unacceptable thoughts, and symmetry subscales of DOCS, BDI, and BAI scores were higher in the OCD with ADHD group than in the OCD only group. The results showed that when depression and anxiety were controlled, "the importance and control of intrusive thoughts" domain of obsessive beliefs was the unique predictor of OCD and ADHD comorbidity. These findings provide a better understanding of cognitive features in OCD patients with ADHD.

Designing the Relationship Obsessive-Compulsive Inventory (ROCI) Based on Iranian Culture and Evaluation of Its Psychometric Properties.

Objective: The purpose of the present study was to evaluate the factor structure, validity, and reliability of the revised Relationship Obsessive-Compulsive Inventory (ROCI), with emphasis on Iranian culture. Method : The statistical sample consisted of 341 married students studying in Tehran universities in the academic year 2018-2019, who were selected by available sampling method. The New ROCI, Obsessive-Compulsive Inventory-Revised (OCI-R), Obsessive Beliefs Questionnaire (OBQ), Depression, Anxiety and Stress Scale (DASS), Dyadic Adjustment Scale (DAS), and Relationship beliefs inventory (RBI) were the tools of the present study. Resul t s: The Content Validity Index (CVI) and Content Validity Ratio (CVR) of the new ROCI were good. Also, there was a significant and negative correlation between all subscales and the total score of the new ROCI with all subscales and the total score of the DAS, and there was also a significant positive correlation between the subscales and the total score of the new ROCI with the subscales and the total score of OBQ, OCI-R, RBI, and DASS. Also, the two factor model explained 54.50% of the variance in the new ROCI. Furthermore, all of the confirmatory factor analysis indices of the new ROCI were better than the original ROCI. The results of test-retest correlation of the factor one and two of ROCI were 0.85 and 0.78, respectively. Also, the Cronbach's alpha of the factor one and two of ROCI were 0.60 and 0.74, respectively. Conclusion: In general, it can be said that the new ROCI was different from the original ROCI, and the new ROCI had better indicators than the original ROCI.

Distinct clinical manifestations of obsessive-compulsive disorder are associated with cortical thickness alteration.

Although brain structural changes have been reported in patients with obsessive-compulsive disorder (OCD), results from previous studies have been inconsistent. A growing number of studies have focused on obsessive beliefs and impulsivity which could be involved in the occurrence and maintenance of OCD symptoms. The present study aimed to examine whether there are distinct brain structural changes in patients with different OCD subgroups. Eighty-nine patients with OCD and 42 healthy controls were recruited to undergo structural magnetic resonance imaging brain scan. OCD patients were classified into subgroups according to scores of the Obsessive Belief Questionnaire (OBQ-44) and the Barratt Impulsiveness Scale (BIS-11) using cluster analysis. Group comparisons in cortical thickness and subcortical volumes between all OCD patients and healthy controls, as well as between subgroups of OCD patients and healthy controls, were carried out. OCD patients with more obsessive beliefs and attentional impulsivity (OCD_OB_AT) had reduced cortical thickness at the inferior parietal gyrus, the superior and middle temporal gyrus and the insula compared with OCD patients with higher score on the non-planning impulsivity (OCD_NP, corrected p < 0.05). The whole group of OCD patients and both subgroups showed reduced cortical thickness at the superior parietal gyrus compared with controls (uncorrected p < 0.01, number of vertices > 100). Our results suggest that apart from distinct phenomenology, there are distinct neural correlates of different OCD subgroups based on obsessive beliefs and impulsivity. These neural correlates may have clinical significance and should be considered in future research.

Sensory experience in obsessive compulsive disorder - sensiocd: Do they think or feel differently?

IntroductionObsessive-compulsive disorder (OCD) is associated to a wide range of symptomatic expression and treatment response variability [1]. Sensory perception has been identified as an emerging factor in this process [2]. Sensory vulnerability and atypical sensory experience were identified as risk factors for the development of OCD [3] and a sensory subtype of the disease was proposed in which there is a positive correlation with early onset sensory symptoms, male gender and family background [4]. Adding to the atypical sensory profile, obsessions are frequently experienced as partially perceptual.ObjectivesOur main goals are to characterize the sensory perception in OCD patients; assess the prevalence and intensity of the sensory properties of the obsessive thoughts and explore the how sensory perception, obsessive thoughts and obsessive dimensions/clusters are interrelated.MethodsPatients with OCD diagnosis, aged 18 to 65 years and no comorbid mental disorder (except depression) will be recruited. The study battery will include participant form with demographical and clinical features, assessment of depressive and anxiety symptoms (HAM-A and HAM-D) evaluation of clinical outcome measures and obsessive dimensions/clusters (Yale-Brown Obsessive-Compulsive Scale (Y-BOQS) and Obsessive Beliefs Questionnaire-44 (OBQ-44)), assessment of sensory perception and sensory properties of obsessive thoughts (Sensory Perception Quotient (SPQ 21) and Sensory Properties of Obsessive Thoughts Questionnaire (SPOQ)).ResultsThe results will help us understand the interaction between perceptual and cognitive processes in OCD.ConclusionsBetter definition of OCD psychopathology and the establishment of a sensory subtype may indicate the need of specific therapeutic indications or a different escalation of treatment measures.DisclosureNo significant relationships.

Obsessive belief and emotional appraisal correlates of symptom dimensions and impairment in obsessive-compulsive disorder.

Background:Obsessive–compulsive disorder (OCD) is a heterogeneous and debilitating illness. Symptom dimensions of OCD lend homogeneous avenues for research. Variations in one's appraisal of thoughts and emotions can influence symptom dimensions and impairment. However, little is known about the combined influence of these appraisals in OCD. A clear understanding of these relationships has putative treatment implications.Aim:The aim of the study is to examine the associations among obsessive beliefs, emotional appraisals, and OCD symptom dimensions in adults.Materials and Methods:We examined 50 drug-naïve/drug-free adults with active OCD. Symptom dimensions and impairment were assessed using the Dimensional Yale–Brown Obsessive–Compulsive Severity Scale. Obsessive beliefs and emotional appraisals were studied using the Obsessive Beliefs Questionnaire-44 and Perception of Threat from Emotion Questionnaire.Results:Tobit regression analysis showed the differential association of obsessive beliefs and symptom dimensions – perfectionism/certainty associated with contamination and responsibility/threat estimation associated with aggressive obsessions. Impairment was associated with dimensional symptom severities and with the perception of threat from anger. This association remained even after controlling for depression severity and obsessive beliefs.Conclusions:OCD symptom dimensions are heterogeneous in underlying obsessive beliefs. Emotional appraisals contribute significantly to impairment alongside symptom severity. Emotion-focused interventions must be included in the psychotherapeutic interventions for OCD.

The Investigation of Transdiagnostic Role of Obsessive Beliefs: Comparison of Clinical Groups Diagnosed with Obsessive Compulsive Disorder, Anxiety Disorders and Depression with University Students.

The present study aimed to investigate whether the dysfunctional obsessive beliefs are specific to obsessive-compulsive disorder (OCD) using three different clinical groups including OCD, depression, and anxiety and a control group of university students. The participants of the study comprised three patient groups with OCD (n=53), major depressive disorder (MDD, n=67), anxiety disorders (AD, n=73), and a group of university students (n=477). The short version of the Obsessive Belief Questionnaire (OBQ-20) was used to measure obsessive beliefs. The Semi-Structured Clinical Interviews for DSM-IV-TR (SCID-I), the Obsessive-Compulsive Inventory- Revised Form, the Beck Depression Inventory, and the State-Trait Anxiety Inventory-Trait Form were used to assess the severity of the symptoms. The scores of the three patient groups were significantly higher on the OBQ-20 as compared to the university students. It is noteworthy that the OBQ-20 scores did not significantly differ between the three patient groups except on the 'importance of thought' (ICT) subscale showing significantly higher scores in the group with OCD in comparison to the patients with depression and anxiety disorders. The results suggest that obsessive beliefs may have a transdiagnostic mechanism with a possible role in the etiology and maintenance of a broad range of different psychopathologies, except in relation to the 'importance and control' of thoughts. Investigating the common processes underlying different psychopathologies is important for the etiological explanation and future treatment of the disorders.
