Maudsley Obsessional-Compulsive Research Articles

Prevalence of obsessive-compulsive symptoms among adult population in primary care centers in Bahrain - A cross-sectional study.

The global increasing prevalence of obsessive-compulsive disorders and symptoms among various age groups and nationalities is considered a great clinical challenge. However, limited data are available on this topic in the Middle East and Gulf Council Countries. This study aimed to raise awareness of obsessive-compulsive symptoms among adults in Bahrain by determining its prevalence and risk factors among patients attending primary healthcare centers. A cross-sectional study was conducted among adult patients attending primary healthcare centers in Bahrain. A self-administered online questionnaire using Google form, a free online survey-creating website, was distributed through WhatsApp messages. A snowball sampling technique was used. The questionnaire consisted of three parts: the socio-demographic data of participants, the Maudsley Obsessional-Compulsive Inventory, and the Yale-Brown Obsessive-Compulsive Scale. Descriptive and inferential analyses were conducted. A total of 614 participants were included with a mean age of 30.04 ± 13.04 years. Most participants were females (82.5%) and single (n = 347, 56.5%). The estimated prevalence of obsessive-compulsive symptoms among the participants was 15%; most of them reported mild symptoms (85%). Significantly higher obsession and compulsion symptoms were found among non-Bahraini (P < 0.001 and P < 0.002), single (P < 0.001 and P < 0.033), and student participants (P < 0.001 and P = 0.002) compared to their counterparts, respectively. In addition, undergraduates reported higher obsessions compared to other participants (P = 0.005). Approximately, one in every eight people in Bahrain were found to suffer from obsessive-compulsive symptoms, especially single, students, and non-Bahraini participants. These findings highlight the need for raising awareness of obsessive-compulsive disorder and its symptoms as well as the importance of early detection and management of obsessive-compulsive disorder.

Determining the Cut-off Scores for the Maudsley Obsessional Compulsive Inventory and the Dimensional Obsessive Compulsive Scale and Reviewing Their Psychometric Properties: Which is More Appropriate for the Evaluation of Obsessive Compulsive Disorder?

Objective: Measurement is essential in psychiatry's clinical and research fields. The cut-off scores of the Maudsley Obsessional Compulsive Inventory (MOCI) and the Dimensional Obsessive Compulsive Scale (DOCS), which are widely used in the evaluation of Obsessive Compulsive Disorder (OCD), have not been determined. Method: DOCS and MOCI were applied to 128 patients with OCD and 124 healthy participants. The psychometric properties of the scales were examined by ROC analysis, confirmatory factor analysis, and Rasch models. Results: The cut-off point has been determined as 25 for the DOCS total score, and 18 for the MOCI. The analysis has been shown that some items in MOCI deteriorated the structure of the scale. In DOCS, it has been shown that almost all scale items are compatible with the scale structure. Conclusion: In this study, the cut-off scores have been calculated for the MOCI and the DOCS, so these two scales have become a more effective and helpful construct. It has been also concluded that the DOCS has more robust psychometric properties than the MOCI.

Obsessive–compulsive symptoms are negatively correlated with motor severity in patients with generalized dystonia

We aimed to clarify the correlations between motor symptoms and obsessive–compulsive symptoms and between the volumes of basal ganglia components and obsessive–compulsive symptoms. We retrospectively included 14 patients with medically intractable, moderate and severe generalized dystonia. The Burke–Fahn–Marsden Dystonia Rating Scale and Maudsley Obsessional Compulsive Inventory were used to evaluate the severity of dystonia and obsessive–compulsive symptoms, respectively. Patients with generalized dystonia were divided into two groups; patients whose Maudsley Obsessional Compulsive Inventory score was lower than 13 (Group 1) and 13 or more (Group 2). Additionally, the total Maudsley Obsessional Compulsive Inventory scores in patients with dystonia were significantly higher than normal volunteers’ scores (p = 0.025). Unexpectedly, Group 2 (high Maudsley Obsessional Compulsive Inventory scores) showed milder motor symptoms than Group 1 (low Maudsley Obsessional Compulsive Inventory scores) (p = 0.016). “Checking” rituals had a strong and significant negative correlation with the Burke–Fahn–Marsden Dystonia Rating Scale (ρ = − 0.71, p = 0.024) and a strong positive correlation with the volumes of both sides of the nucleus accumbens (right: ρ = 0.72, p = 0.023; left: ρ = 0.70, p = 0.034). Our results may provide insights into the pathogenesis of obsessive–compulsive disorder and dystonia.

Frequency of Obsessive-Compulsive Symptoms Related to Anxiety in Nurses Care for COVID-19 Patients: A Cross-sectional Study

Background: Obsessive-compulsive disorder (OCD) is one of the most prevalent anxiety-related disorders caused by many environmental factors, including anxiety. The COVID-19 outbreak has exposed nurses to greater levels of occupational anxiety. Objectives: This study aimed to investigate the frequency of obsessive-compulsive (OC) symptoms and the relationship between OC symptoms and anxiety in nurses of COVID-19 patients at Dr. Ganjavian hospital, Dezful, Iran. Methods: This cross-sectional study encompassed 190 nurses working in units for COVID-19 patients meeting the inclusion criteria. They were evaluated using a demographic characteristics form, the Maudsley Obsessional Compulsive Inventory (MOCI), and the Spielberger State-Trait Anxiety Inventory (STAI) (Spielberger, 1983). Sampling was performed via a stratified random sampling method. The collected data were analyzed using descriptive statistics (absolute frequency and percentage) and analytical statistics (Pearson correlation coefficient and independent t-test) via SPSS version 21 at a significance level of 0.05. Results: The study revealed that 74.4% of the participants showed OC symptoms, 47.4% stated anxiety below moderate, and 61.1% trait anxiety above moderate. The results of the Pearson correlation displayed that OC symptoms were significantly associated with state/trait anxiety (P = 0.001). Furthermore, the independent t-test indicated that the mean score of OC symptoms was significantly higher in females (P = 0.03) and married subjects (P = 0.006). Conclusions: The frequency of OC symptoms was high in nurses working in COVID-19 units, especially females and married subjects. There was also a significant relationship between OC symptoms and anxiety, such that anxiety increased with OC symptoms. Thus, it is suggested that nursing managers identify anxiety-causing factors in nurses to prevent more severe anxiety disorders.

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.

Effectiveness of a Constructive Model of Variables related to Depersonalization- Derealization Disorder of University Students

The aims of this study were to identify the correlation between Depersonalization - Derealization Disorder (DPDR), anxiety, depression, and obsessive-compulsive disorders and to propose a constructive model of anxiety, depression and obsessive- compulsive disorders related to Depersonalization Derealization Disorder of university students. The sample consisted of 344 students (325 female and 19 male), with a mean age of (24.4) years. The study applied the following scales: structured clinical interview for depersonalization-derealization spectrum, Cambridge Depersonalization Scale, Generalised anxiety scale (GAD-7), Hamilton Depression Rating Scale and Maudsley Obsessional–Compulsive Inventory. Results indicated that obsessive-compulsive disorder and depression played a major role in developing DPDR due to a significant positive effect of these disorders, while anxiety had a weak correlation. The study developed a constructive model of variables related to DPDR based on AMOS software. The results illustrated that the contribution of obsessive-compulsive and depression as independent variables in predicting PDRD was 61.8 and 44.9, respectively, while no effect of anxiety was recorded. The findings also developed a model for the causal relationships between anxiety, depression, and obsessive-compulsive influence on DPDR disorder. The results of the causal model test indicated that the obsessive-compulsive variable is hypothesized to be a mediator in influencing the DPDR disorder as it is affected by both anxiety and depression.

Prevalence and Clinical Presentations of Postpartum Obsessive-Compulsive Disorder in Iranian Pregnant Women

Introduction: Pregnancy, childbirth, and maternity are correlated with the heightened risk of the evolvement of postpartum obsessive-compulsive symptoms. This study aimed to inquire about the prevalence rate, clinical presentations, and relevant factors of postpartum Obsessive-Compulsive Symptoms (OCS). Method: This cross-sectional study evaluated OCD in the postpartum period of women referred to the Imam Hospital in Sari, Mazandaran province, Iran. The sample population included 359 pregnant women who delivered their babies during the first half of 2018. The samples were taken using the convenience sampling method. Patients who scored 12 or higher in the Maudsley Obsessive-Compulsive Inventory completed the Yale-Browne Obsessive-Compulsive Scale self-report, and the Life Event Checklist were included in the study. Finally, data were analyzed using IBM SPSS version 24. Results: The 359 mothers were in the range of 14 to 35 years old. Accordingly, 62.1% (223) were urban women while 37.9% (136) were rural, 20.6% (74) had preterm infants, 56.8% (204) term infants, and 22.3% (80) were post-term. Maudsley’s test showed that 48.5% (174) of the mothers had a positive OCD result. The total scorein Yale-Brown was significant, and had a reverse correlation with the mother’s residency (t = -173, p = 0.02) and significant correlation with the age of a pregnancy (t = 269, p= 0.001(. Conclusion: According to the results of the Maudsley test, women are at risk of OCD during the postpartum period. Actually, OCD affects the mother-baby relation, mother’s anxiety, and depression and should be addressed during womens’ postpartum clinical care.

Prevalence of Body Dysmorphic Disorder Among a Group of College Students in Shiraz

Background: Body dysmorphic disorder (BDD) is a relatively common and often severe psychiatric disorder. This disorder is a highly distressing disorder associated with poor quality of life. In addition, it is characterized by persistent and intrusive preoccupation with perceived defects or flaws in one’s physical appearance accompanied by repetitive behaviors such as mirror checking, excessive grooming, and reassurance seeking. Objectives: The purpose of this study was to examine the prevalence of BDD symptoms and body dissatisfaction among college students. Furthermore, the current study examined students’ checking behaviors and the parts of the body that they were most concerned about. This research also sought to examine the comorbidities associated with BDD symptoms, such as eating disorders, obsessive-compulsive disorder, depression, and social anxiety. Methods: A total of 750 college students were recruited from different schools of the Shiraz University, including Social Science, Engineering, Art, Education and Psychology, and Science and Art, using the cluster sampling method. Two classes were randomly selected in each school, and those who were volunteers took part in this study. Participants completed several questionnaires, including the Body Dysmorphic Disorder Questionnaire, Beck Depression Inventory, Maudsley Obsessive-Compulsive Disorder Scale, Social Phobia Inventory, and Eating Attitude Test. To analyze the data, statistics methods, such as frequency, percentage, mean, standard deviation and chi-squared test were used. Results: The results of this study showed that about 77% of college students were dissatisfied with at least one part of their bodies. The findings also revealed that the prevalence of BDD symptoms among college students was 4.5%. Furthermore, our results indicated that college students were mostly concerned about the appearance of their skin followed by hair, nose, weight, stomach, height, teeth, breast, and other parts of the body. In terms of checking behaviors, checking in front of a mirror, reassurance seeking, seeking treatment, and comparing themselves with others were the most common behaviors. The most prevalent comorbidity associated with BDD symptoms was obsessive compulsive disorder followed by social anxiety, depression, and eating disorders. Conclusions: This study highlighted that the majority of college students were dissatisfied with their bodies. This research also showed that college students are at high risk of mental health problems.

Misophonic symptoms in non-psychotic psychiatric outpatients and its association with trait psychological variables

Misophonia is commonly described as abnormal or disproportionately aversive and emotional reactions to specific sounds that interfere with patients’ psychosocial functioning. In this study, we aimed to investigate the possible associations of specific psychological traits with misophonic symptoms in psychiatric outpatients. Misophonic Symptoms Checklist (MSC), Eysenck Personality Questionnaire-Revised Short Form (EPQRS), Maudsley Obsessive-Compulsive Inventory (MOCI), State-Trait Anxiety Inventory (STAI), Buss-Perry Aggression Questionnaire (BPAQ) and Somatosensory Amplification Scale (SASS) were used to assess various psychological traits in a sample of consecutive outpatients at University Hospital Psychiatry Department in September 2019. After multiple regression analysis, we found that the MOCI, STAI, EPQRSneuroticism, SASS, and BPAQ predicted misophonic symptoms where only SASS and MOCI were significant predictors. Our findings indicate that proneness to somatization and obsessivecompulsive symptoms are significantly associated with misophonic symptoms. These findings contribute to the phenomenological understanding of misophonia. • Misophonia is related to many psychological trait variables. • Obsessive, aggressive, anxious, and neurotic traits were related to misophonia. • Association between obsessive trait and misophonia is robust in psychiatric sample. • Somatosensory amplification predicts misophonic symptom severity.

Comparing the Effectiveness of Schema Therapy and Emotional Schema Therapy on Emotion Regulation of Individuals with Obsessive Compulsive Symptoms

Abstract Introduction: Due to the prevalence of Obsessive Compulsive Symptoms (OCS), it seems that actions should be taken to prevent its recurrence. Therefore, the purpose of the present study was to compare the effectiveness of Schema Therapy (ST) and Emotional Schema Therapy (EST) on the emotion regulation of patients with OCS. Method: This semi-experimental study was carried out on 24 patients with OSC in three groups of ST (n=8), EST (n=8) and control (n=8) in Mashhad, Iran. The intervention groups received individual EST and ST Sessions. The data were collected by Maudsley Obsessive-Compulsive Scale (MOCAI) and Emotion Regulation Questionnaire (ERQ) in four stages of pre-test, post-test, one and three months follow up. The MANOVA test was utilized to analyze data. Results: During the above stages, the mean score of expressive suppression and cognitive reappraisal subscales fell and soared significantly in the EST group, respectively (p <0.05). There was a significant difference between the groups of intervention and control in terms of the average total obsessive-compulsive score and its sub-scales except for the slow sub-scales during all three stages after the intervention, one month later and three months later (p <0.05). Conclusion: Although both ST and EST methods had an effect on the improvement of emotion regulation and OCS, the EST was more effective on improving emotion regulation. Therefore, it is recommended to consider EST with a larger sample size in people with OCS.

The Revised Arabic Scale of Obsession-Compulsion (ASOC): Validation with Iranian psychiatric outpatients

ABSTRACT The aims of the present study were (a) to develop a Farsi version of the Revised Arabic Scale of Obsession-Compulsion (ASOC), (b) to investigate its psychometric properties, (c) to explore its correlations with another scale of obsession-compulsion, as well as scales of depression, somatic symptoms, and religiosity, (d) to explore its factorial structure, and (e) to estimate sex-related differences. A sample of 111 Iranian psychiatric outpatients was recruited. They responded to the Farsi versions of the ASOC, the Maudsley Obsessional-Compulsive Inventory (MOCI), Patient Health Questionnaire-2 (PHQ-2), Somatic Symptoms Scale (SSS), and Self-Rating Scale for Religiosity (SRR). Cronbach’ α was .89 for the ASOC, and five salient components were extracted. All the correlations between the ASOC scores were statistically significant and positive with the other scales (except for the SRR scores). Patients who had more obsessive-compulsive symptoms had more depression and somatic symptoms. The sex-related difference in the ASOC was not significant. This study provides evidence for the usefulness of the ASOC for assessing OC symptoms in Iranian psychiatric outpatients and extends existing research about the measure’s factor structure.

Social provision partially mediates the complex associations among posttraumatic stress, obsessive-compulsive and depressive symptoms in traumatized patients.

To identify the associations among posttraumatic stress, depressive and obsessive-compulsive symptoms (OCS) in outpatients with psychological trauma and to examine the mediating effect of social provision. Psychologically traumatized patients simultaneously experience depressive and OCS. Social provision may mediate multiple symptoms differently compared with social support. Cross-sectional and correlational study. Data were collected between August 2016-May 2017. Psychiatric outpatients (N=151) completed a structured questionnaire consisting of the Korean versions of the Social Provision Scale, Beck Depression Inventory-II, Maudsley Obsessional-Compulsive Inventory and Impact of Event Scale-Revised. Structural equation modelling was used to examine the recursive association among the three symptoms and the mediation of social provision. There was a recursive association between posttraumatic stress symptoms (PTSS) and depressive symptoms, which were simultaneously associated with OCS with a one-way direction. OCS and social provision partially mediated these identified associations among three symptoms. Our findings provide insight into the complex associations of multiple symptoms experienced by traumatized outpatients and the partial mediation of social provision. Psychiatric and mental health professionals may enhance social functioning and interpersonal interactions based on social provision components used for helping traumatized patients with obsessive-compulsive and depressive symptoms. There was a recursive association between PTSS and depressive symptoms that were simultaneously associated with OCS with a one-way direction. Social provision functions as a partial mediator when working with OCS. Mental health nurses can develop social provision interventions for depressive symptoms for traumatized outpatients with OCS.

The prevalence and risk factors of orthorexia nervosa among school-age youth of Pomeranian and Warmian-Masurian voivodeships.

The aim of the study was to determine the prevalence of orthorexia nervosa among school-age youth from Pomeranian and Warmian-Masurian voivodeships, as well as search for factors which enhance the risk of orthorexia nervosa. An attempt was made to find differences in occurrence of orthorexia nervosa among youth from big cities and small towns. The study group consisted of 864 subjects (599 females and 265 males). The mean age of female participants was 20.21+/-3.27 years, and of male participants - 18.93+/-3.67 years. In the study, we used a proprietary questionnaire to collect patient data, as well as following diagnostic questionnaires: ORTO-15 by Donini et al. (Polish version validated by Stochel, Janas-Kozik et al.), EAT-26 by Garner and Garfinkel, MOCI (Maudsley Obsessive-Compulsive Inventory) by Hodgson and Rachman, and BDI-II (Beck Depression Inventory II) by Beck. The results were statistically analyzed. 27% of subjects were found to be at risk of orthorexia nervosa (score of 35 was consideredas cut-off point). The highest score of risk was observed in the group of students of junior secondary school, the lowest in the group of students of senior secondary school. There were no statistically significant differences in the risk of orthorexia in groups from big city and small town. Studied social factors did not show impact on the risk of orthorexia. Individuals with suspected orthorexia have notably higher BMI. There were no statistically significant differences in occurrence and severity of depression in the study group. Depression occurred in 25% of the subjects;the link between depression and orthorexia was not confirmed. On the basis of the study, it was indicated that the group of the highest risk are students of junior secondary school, probably because of the great interest in physical attractiveness in this period of life, as well as individuals with higher BMI. We believe that for more effective diagnosis it would be advisable to adopt a cut-off point for orthorexia in the ORTO-15 at the level of 35 points, as postulated by Stochel, Janas-Kozik et al. The 40-point threshold is associated with considerable overdiagnosis of the phenomenon.

The Role of Anxiety Sensitivity, Intolerance of Uncertainty, and Obsessive-Compulsive Symptoms in the prediction of Cyberchondria

Frequent search for health-related data on the internet that escalates anxiety experience is called cyberchondria. The aim of this study was to determine the role of anxiety sensitivity, intolerance of uncertainty and obsessive-compulsive symptoms in the prediction of cyberchondria. The study was performed on 177 students of Tabriz University, Tabriz, Iran. The samples were recruited using clustering sampling method. Data were collected using Cyberchondria Sensitivity Scale (CSS), Anxiety Sensitivity Index-Revised (ASIR), Maudsley Obsessive-Compulsive Inventory (MOCI), and Intolerance of Uncertainty Scale (IUS). According to the regression analysis, anxiety sensitivity, intolerance of uncertainty and obsessive-compulsive symptoms positively and significantly predicted cyberchondria. According to the results, the interpretation of physical sensations as dangers, uncertainty about the origin of these senses, and the feeling of responsibility and coercion to be sure about the health leads the individual to frequently search medical information through the Internet.

An unhealthy health behavior: analysis of orthorexic tendencies among Hungarian gym attendees.

In the present study, we aim to assess the prevalence and certain psychological and other correlates of orthorexic tendencies: health and exercise behaviors and demographic variables among gym attendees in Hungary. Altogether, responses of 207 gym attendees who filled out an online questionnaire (03/2017-10/2017) were analyzed. The mean age was 31.9years; most were female and college educated, and about half resided in the capital city. Frequencies and means were calculated for the sample; and univariate linear regression and ANOVA were carried out. Finally, multivariate linear regression was used to assess the relationship between the dependent variable (Orto-11-Hu) and the independent variables (Eating Disorder Inventory, Maudsley Obsessional-Compulsive Inventory, health and exercise habits, and demographics). The mean score for the Orto-11-Hu was 27.7. In the multivariate analysis, two eating disorder characteristics (drive for thinness and interpersonal distrust), age, exercising more than once a day, and yoga practice were significantly associated with higher orthorexic tendencies. There was a lack of correlation between any obsessive-compulsive traits. Our data suggest and overlap between certain eating disorder traits, and a link between ON and frequent exercising and younger age. Further research is needed to investigate whether these correlates are found not only in a specific fitness-oriented population, but also in the general population. Level V, descriptive cross-sectional study.

Cognitive Profile of Individuals With Obsessive-Compulsive Tendencies

Abstract The aim of this study is to compare working memory capacity (WMC), short-term memory (STM), and attention mechanisms of executive function (including inhibition, shifting, and updating) between people with obsessive-compulsive tendencies (OCT) and controls without OCT. For this purpose, 164 undergraduate students (90 women and 74 men) were selected using the stratified random method, and they individually responded to the Maudsley Obsessional-Compulsive Inventory to measure OCT and to executive function tests including Forward Digit Span, Backward Digit Span, Stroop, Set Shifting, and Keep Track tasks. These tasks assessed STM, WMC, and inhibition of prepotent responses, mental set shifting, and information updating and monitoring, respectively. In this study, the cutoff point of the Maudsley Obsessional-Compulsive Inventory was considered to be 11. With regard to this cutoff point, 44 people in the group had OCT and 120 did not. The obtained results from the Pearson correlation coefficient and analysis of variance showed that students with OCT had significantly limited STM and WMC compared with those in the control group. Furthermore, their executive function abilities including shifting, updating, and inhibition were significantly weaker than those in the control group.

Attachment styles of patients with major depressive, obsessive-compulsive, and generalized anxiety disorders

Introduction: This study was conducted in order to compare the attachment styles of the patients suffering from major depression disorder (MDD), obsessive-compulsive disorder (OCD) and generalized anxiety disorder (GAD) with those of the healthy people. Methods: In this case-control study, a total number of 60 male/female patients with MDD and OCD were categorized into three 20-subject groups, then 20 healthy people were included in one control group. The study instruments were Hazan and Shaver's Attachment Style Questionnaire (version 1993), Beck Depression Inventory (BDI-II), Maudsley Obsessive-Compulsive Inventory (MOCI), Penn State Worry Questionnaire (PSWQ), and Beck Anxiety Inventory (BAI). The data were analyzed using chi-square test. Results: There was a significant difference between the attachment styles of the healthy people and the patients suffering from MDD (P < 0.001), OCD (P = 0.013) and GAD (P = 0.013). Moreover, a significant difference was observed between the attachment styles of patients with MDD, OCD (P = 0.012) and GAD (P = 0.010). These findings indicated that patients with MDD were more insecurely attached in comparison to patients with OCD and GAD. However, there was no significant difference between the attachment styles of patients with OCD and GAD (P = 0.089). Conclusion: This study indicated that there was a significant difference between the attachment styles of patients with MDD, OCD, and GAD, and the healthy people. This finding indicates that in the etiology of mental disorders, the effects of attachment styles should not be disregarded.

Metacognitive Beliefs and Their Relation with Symptoms in Obsessive-Compulsive Disorder.

Metacognitive constructs have shown promise in explaining the symptoms of Obsessive-Compulsive Disorder (OCD). Few studies have examined the role of metacognitions in symptom dimensions of OCD, despite mounting clinical, neuropsychological and imaging evidence for the distinctiveness of these dimensions. Metacognitions were assessed using the Metacognitions Questionnaire (MCQ-30) in 51 participants with DSM IV OCD and 46 healthy controls. The Maudsley Obsessional Compulsive Inventory (MOCI) was used to quantify symptom dimensions, along with the Hamilton Anxiety Rating Scale (HAM-A) for anxiety, and Hamilton Depression Rating Scale (HAM-D) for depression. Individuals with OCD differed from healthy controls on beliefs of uncontrollability and danger when depression and anxiety were controlled for. Correlations between metacognitive beliefs and obsessive-compulsive symptom dimensions were largely similar across the OCD and healthy control groups. Hierarchical regression showed that need to control thoughts contributed to checking, cleaning and rumination symptoms; cognitive self-consciousness to symptoms of slowness; uncontrollability and danger to doubt symptoms; positive beliefs to checking symptoms. Specific associations between metacognitive variables and the different symptom dimensions of OCD are evident, however, severity of anxiety and depression also contribute to these associations.

Anger level and depression relation in children and adolescents with obsessive compulsive disorder

Objective: In this study, we examined sociodemographic characteristics and distribution of comorbid psychiatric disorders in children and adolescents diagnosing OCD, anger level and its association with comorbid disorders. Methods: Sample of this study is formed by 11-18 aged children and adolescents, made an application to Karadeniz Technical University, Child and Adolescent Mental Health and Diseases Policlinic, which are diagnosed OCD according to DSM-5 whom intelligence level is normally detected. The control group, selected from the community with non-randomly, is composed of 50 children and adolescents, matched for age, and gender group with OCD and had no physical and mental chronic disease. Sociodemographic characteristics was detected using Semi-Struc-tured Interview Form, comorbid disorders was determined to predicating the DSM-5 criteria. The Child Depression Inventory, The Screen for Child Anxiety Related Emotional Disorders, Yale-Brown Obsessive and Compulsive Scale for Children’, Maudsley Obsessive-Compulsive Inventory and Anger Scale are given child and adolescents. WISC-R or Stanford Binet tests were applied. Results: In OCD group the most common comorbid disorder was anxiety disorder (72%), the second was depressive disorder (32%), which accompanied the tiger to 8% of patients. Depres-sive disorders and anxiety disorders were most frequently in OCD group than the control group. In OCD group OCD severity scores and anger in scores, trait anger scores and anger in and out scores, anger in scores and anger out scores were positively correlated and trait anger and anger control scores, anger out and anger control scores were negatively correlated. Yale Brown OCD severity scores, depression and anxiety scores, depression scores, and anxiety scores were positively correlated. Discussion: OCD severity scores was associated with anger level scores and anxiety and depression scores in cases.

Reliability and validity of the Japanese version of the Obsessive-Compulsive Inventory-Revised (OCI-R)

The objective of the present study was to investigate the factor structure, and the reliability and validity of the Japanese version of the Obsessive-Compulsive Inventory-Revised (OCI-R). The participants included 214 university students enrolled at two universities in a metropolitan area. They completed the OCI-R and other related scales, and of these, 38 students answered the OCI-R again two weeks later. Based on a factor analysis, the six-factor structure, the same as the original version, was confirmed. For reliability, internal consistency and test-retest reliability were evaluated and both internal consistency and test-retest reliability were confirmed. For convergent validity, we calculated the correlation coefficient using the Japanese version of the Maudsley Obsessional-Compulsive Inventory, which measures obsessive-compulsive symptoms. For concurrent validity, we calculated the correlation coefficient using the Patient Health Questionnaire-9, which measures depressive symptoms; and the Generalized Anxiety Disorder-7, which measures anxiety symptoms. Overall, the factor structure, the reliability, and the validity of the Japanese version of the OCI-R were all confirmed in this study. In the future, we will investigate whether the same results can be obtained in clinical groups.
