Possible Vicarious Traumatization Among Psychiatric Inpatients During the Remission Phase of the COVID-19: A Single-Center Cross-Sectional Study.

Background: Far from being a clinical disease, the COVID-19 pandemic has become a threatening social event worldwide exerting long-term impacts on human beings.Objective: This study was designed to determine if and to what extent psychiatric inpatients during the remission phase of the pandemic suffered from vicarious traumatization.Method: Totally 266 eligible participants from psychiatric and psychological wards in a hospital were recruited during October 26th, 2020 to February 4th, 2021 to finish a self-made online questionnaire consisting of Impact of Event Scale-Revised (IES-R), Self-Rating Depression Scale (SDS), Self-Rating Anxiety Scale (SAS), Obsessive-Compulsive Inventory-Revised (OCI-R), Pittsburgh Sleep Quality Index-Revised (PSQI-R), Social Support Rating Scale (SSRS), Beck Suicide Ideation Scale (SSI), 12-Item Short-Form Health Survey (SF-12). Meanwhile, some socio-demographics and information related to the pandemic were also recorded.Results: The detection rate of vicarious traumatic symptoms (VTS) was 80.83%, including 40.98% for mild ones, 25.56% for moderate ones, and 14.29% for severe ones, among whom 98.14% possessed all three phenotypes. 27.07% of the sample were considered possible vicarious traumatization (pVT). Having acquaintances infected with or died from COVID-19, worries on re-outbreak of COVID-19, a higher score of OCI-R or lower score of SF-12, and long latency of VTS were independent risk factors of pVT.Conclusion: Our study showed that COVID-19 could have profound mental influences on psychiatric inpatients. It is high time we did some screening in the wards to seek for patients at risk.

The Relationship between Child Abuse and Cognitive Distortions with Clinical Symptoms of Obsessive-Compulsive Disorder: The Mediating Role of Emotion Dysregulation

Introduction: The present study has aimed to investigate the relationship between child abuse and cognitive distortion with clinical symptoms of obsessive-compulsive disorder moderated with emotion dysregulation.Method: This study made use of descriptive correlational research design. Structural equation modeling was used to explore the relationships between variables. The statistical population included all students of Urmia University in April 2019 (N=17000). The sample included 201 students who were selected by multi-stage cluster sampling. In this study, the Obsessive-Compulsive Inventory-Revised (OCI-R) (2002), the Child Abuse Scale (CAS) (1392), the Cognitive Distortions Scale (CDS) (1389) and Difficulty in Emotion Regulation Scale (DERS) (2004) were used to collect data. In order to analyze the data, descriptive and inferential statistics and used SPSS-21 and AMOS software were used.Results: Pearson correlation coefficient and structural equations modeling showed that the structural model has a good fit with data. In this research, the direct effect of child abuse on emotion dysregulation (β=0/46, P=0/002), child abuse on clinical symptoms of Obsessive-Compulsive Disorder (OCD) (β=0/43, P=0/003), cognitive distortions on emotion dysregulation (β=0/57, P=0/001), and cognitive distortions on clinical symptoms of OCD (β=0/51, P=0/001) were approved. The bootstrap test results showed significant indirect effects of child abuse and cognitive distortion on clinical symptoms of OCD which operate via emotion dysregulation.Conclusion: It seems that emotion dysregulation has a mediating role in the incidence of OCD. As a result, it is recommended to attend to OCD patient’s emotion dysregulation problems and educate them on the adaptive skills of emotion regulation.

Short communication: A report of the first twelve months of an early intervention service for obsessive-compulsive disorder (OCD)

ObjectivesTo present a report on the first twelve months of an early intervention service for patients with obsessive-compulsive and related disorders. MethodsDemographic and clinical data including changes in the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) and the Obsessive Compulsive Inventory – Revised (OCI-R) were reported for 48 patients referred to the Western Sydney Obsessive-Compulsive and Related Disorders Service during the first 12 months of its operation. ResultsThe service provided education, training and specialised quaternary level assessment and recommendations to patients who have already been assessed by a psychiatrist and/or mental health worker within early intervention teams for psychosis, anxiety clinics and other public psychiatric services. The service failed to reach OCD sufferers early in their course of illness with the mean time from symptom onset being 9.4 years. The use of objective measures such as the Y-BOCS and OCI-R at follow-up was poor and 86.0% (n = 37) remained in treatment at 12 months. ConclusionsAn early intervention service for OCD is unlikely to be able to assist sufferers early in their course of illness if it is associated with quaternary clinical services or early intervention programmes for psychosis. Efforts might be better focused on providing education and on early screening of young people in non-clinical settings.

Italian adaptation of the Düsseldorf Orthorexia Scale (I-DOS): psychometric properties and prevalence of orthorexia nervosa among an Italian sample

PurposeOrthorexia Nervosa (ON) is described as an extreme level of preoccupation around healthy eating, accompanied by restrictive eating behaviors. During the years, different assessment instruments have been developed. The aim of the study is to adapt into Italian the Düsseldorf Orthorexia Scale (I-DOS) and to test its psychometric properties.MethodA total sample of 422 volunteer university students (mean age = 20.70 ± 3.44, women 71.8%) completed a group of self-report questionnaires in large group sessions during their lecture time. The scales assessed ON (the I-DOS and the Orhto-15), disordered eating (Disordered Eating Questionnaire, DEQ), depressive symptoms (Beck Depression Inventory-II, BDI-II), obsessive and compulsive symptoms (Obsessive Compulsive Inventory-Revised, OCI-R), and self-reported height and weight.ResultsThe fit of the unidimensional structure and reliability of the I-DOS was tested trough Confirmatory Factor Analysis (CFA) as well as its criterion validity computing correlation coefficients among Ortho-15, DEQ, BDI-II, OCI-R, BMI. Analyses confirmed the unidimensional structure of the I-DOS with acceptable or great fit indices (CFI = 0.984; TLI = 0.978; SRMR = 0.043; RMSEA = 0.076) and the strong internal consistency (α = 0.888). The correlations path supported the criterion validity of the scale. The estimated total prevalence of both ON and ON risk was 8.1%.ConclusionsThis 10-item scale appears to be a valid and reliable measure to assess orthorexic behaviors and attitudes.Level of evidenceLevel V, descriptive cross-sectional study.

Study Protocol-Coping With the Pandemics: What Works Best to Reduce Anxiety and Depressive Symptoms.

Background: The coronavirus disease 2019 (COVID-19) pandemic and lockdown might increase anxiety and depressive symptoms in most individuals. Health bodies recommend several coping behaviors to protect against such symptoms, but evidence on the relationship between these behaviors and symptoms mostly comes from cross-sectional studies in convenience samples. We will conduct a prospective longitudinal study of the associations between coping behaviors and subsequent anxiety and depressive symptoms during the COVID-19 pandemic in a representative sample of the Spanish general adult population.Methods: We will recruit 1,000 adult participants from all autonomous communities of Spain and with sex, age, and urbanicity distributions similar to those of their populations and assess anxiety and depressive symptoms and coping behaviors using fortnightly questionnaires and real-time methods (ecological momentary assessments) for 1 year. The fortnightly questionnaires will inquire about anxiety and depressive symptoms [General Anxiety Disorder-7 (GAD-7) and Patient Health Questionnaire-9 (PHQ-9)] and the frequency of 10 potential coping behaviors (e.g., follow a routine) during the past 2 weeks. In addition, we will collect several variables that could confound or moderate these associations. These will include subjective well-being [International Positive and Negative Affect Schedule Short Form (I-PANAS-SF) and Satisfaction with Life Scale (SWLS)], obsessive-compulsive symptoms [Obsessive Compulsive Inventory-Revised (OCI-R)], personality and emotional intelligence [International Personality Item Pool (IPIP) and Trait Emotional Intelligence Questionnaire Short Form (TEIQue-SF)], sociodemographic factors (e.g., work status, housing-built environment), and COVID-19 pandemic-related variables (e.g., hospitalizations or limitations in social gatherings). Finally, to analyze the primary relationship between coping behaviors and subsequent anxiety and depressive symptoms, we will use autoregressive moving average (ARMA) models.Discussion: Based on the study results, we will develop evidence-based, clear, and specific recommendations on coping behaviors during the COVID-19 pandemic and lockdown. Such suggestions might eventually help health bodies or individuals to manage current or future pandemics.

Psychometric Properties of the Persian Version of the Dimensional Obsessive-Compulsive Scale in A Non-clinical Population

Objective: Measuring, diagnosing, and determining the severity of the symptoms of Obsessive-Compulsive Disorder (OCD) is essential for studying mental health issues. This study aimed to determine the psychometric properties of the Persian version of the Dimensional Obsessive-Compulsive Scale (DOCS) in a non-clinical population. Methods: In this cross-sectional study, 252 residents of Tehran (Iran) were selected by cluster sampling method from different districts. They were asked to complete DOCS, Yale-Brown Obsessive-Compulsive Scale (Y-BOCS), and Obsessive-Compulsive Inventory-Revised (OCI-R). SPSS v. 21 and LISREL statistical software were used for data analysis. Cronbach's alpha, exploratory and confirmatory factor analysis, Spearman correlation were also used. Results: The Internal consistency of DOCS was 0.916 based on the Cronbach α value. The correlations of DOCS with Y-BOCS and OCI-R were 0.57 and 0.55, respectively. Exploratory factor analysis showed four factors. Confirmatory factor analysis also showed that this four-factor and higher-order factor models had a good fit for the data. Conclusion: The present study indicated acceptable validity and reliability of DOCS in non-clinical populations in Iran. Therefore, this scale be used to screen people with OCD symptoms in non-clinical centers of mental health assessment.

Low intensity technology-delivered cognitive behavioral therapy for obsessive-compulsive disorder: a meta-analysis

BackgroundCognitive behavioral therapy (CBT) is a well-established treatment for people suffering from obsessive-compulsive disorder (OCD) and technology-based CBT applications are an emerging treatment option for people with OCD. These applications involve treatment protocols with automated content delivery and relatively low clinical contact. Whilst such CBT applications are promising, however, further investigation is needed to establish the efficacy of this treatment approach for individuals with OCD. The aim of the present study was to review the efficacy of technology-delivered CBT with minimal clinician support for OCD using a meta-analytic approach.MethodsRandomized controlled trials (RCT) were identified through PsycINFO, Medline and Scopus resulting in 18 eligible studies (n = 1707). Control conditions comprised both passive (namely no treatment, other treatments and waitlist controls) and active. Measurement of OCD symptoms improvement was the outcome in each study.ResultsParticipants in the technology-delivered CBT group scored lower on Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) (g = − 0.59, 95% CI = [− 0.99, − 0.18], p = 0.01), Y-BOCS and Dimensional Obsessive-Compulsive Scale (DOCS) combined (g = − 0.55, 95% CI = [− 0.87, − 0.24], p = 0.003) and Obsessive-Compulsive-Inventory-Revised (OCI-R) (g = − 0.36, 95% CI = [− 0.62, − 0.09], p = 0.02) at post-treatment than passive control groups. There were no significant findings when compared to controls with other treatments.ConclusionsThis meta-analysis suggests that technology-delivered CBT with low personal contact intensity, relative to passive control groups, is an efficacious and promising treatment option for individuals with OCD. Further research is needed to allow for a comparison with control groups with other treatments.

Compulsive Hoarding Symptoms and the Role of Mindfulness Skills During Social Distancing for the COVID-19 Pandemic: An Exploratory Survey.

People reporting compulsive hoarding symptoms (CHS) have lower mindfulness skills than those without such symptoms. Mindfulness skills can have the role of a protective buffer against stressful periods. The quarantine imposed to contain the COVID-19 spread had a negative impact on daily habits and healthy behaviors (including social interactions). An increased attachment to objects might be one of the under-recognized psychological consequences of these difficult times, yet no study focused on CHS. Through an online survey in men who were on quarantine during the pandemic, this exploratory survey examined the prevalence of men reporting CHS during this period and explored the role of mindfulness skills on CHS controlling for anxious-depressive/stress symptoms. Forty-three men from the general population completed the Obsessive Compulsive Inventory-Revised (OCI-R), Cognitive and Affective Mindfulness Scale-Revised (CAMS-R) and Depression Anxiety Stress Scales-21 (DASS-21). Twenty-eight percent reported CHS. No differences on the scores of the questionnaires emerged between men with and without CHS, except on CAMS-R Attention scores. In a logistic regression analysis lower CAMS-R Attention scores predicted CHS (β = −0.34, p = 0.03). This is the first, yet preliminary investigation on CHS during quarantine. The prevalence of CHS appears higher than the rates (4%) reported in the last years before the COVID-19 outbreak. Perhaps people showed more intense hoarding tendencies during quarantine/social distancing, and this pattern should be monitored. Larger samples, longitudinal designs and clinician-rated instruments are needed to support or not our findings.

COVID-19 pandemic fears and obsessive-compulsive symptoms in adolescents with pre-existing mental disorders: An exploratory cross-sectional study.

Background:Previous research has established an association between pandemic fears and the development of obsessive-compulsive symptoms mainly in the general population.Aim:To explore whether COVID-19 pandemic fears are associated with obsessive-compulsive symptoms and vice versa in adolescents with preexisting mental and behavioural disorders.Methods:A questionnaire-based cross-sectional study among adolescents with pre-existing mental disorders. The extent of worrying related to the COVID-19 pandemic was measured using the COVID-19 inventory whereas obsessive-compulsive symptoms were assessed using the obsessive-compulsive inventory-revised (OCI-R). Pearson correlation coefficient (r) was used to explore the relationship between COVID-19 pandemic fears and the development of obsessive-compulsive symptoms.Results:A total of 57 patients out of 63 participants (90.4%) had a COVID-19 inventory score of 12 or higher suggesting that a vast majority of young people with mental disorders had significant pandemic-related worries. Out of these 57 patients, over half (31) had an OCI-R modified score of 17 or higher indicating significant obsessive-compulsive symptoms. A positive correlation was found between the means of the two scores. This relationship was statistically significant – {r = 0.405, Sig. (two-tailed) = 0.001}.Conclusion:Adolescents with mental disorders can exhibit significant pandemic fears and this is likely to be associated with obsessive-compulsive symptoms.

Autistic traits predict obsessive-compulsive symptoms: Study in a clinical sample

IntroductionCo-occurrence of obsessive-compulsive disorder (OCD) and autism spectrum disorder (ASD) features is well stablished. Diagnosis of OCD increases the risk of a later diagnosis of ASD, and vice versa. Moreover, a recent combined genome-wide association study identified a shared polygenic risk between the two disorders. Our preliminary results also indicate that OCD patients have higher levels of autistic traits than individuals from the community.ObjectivesTo determine which autistic dimensions (social skill, communication, attention switching, attention to detail imagination) are predictors of OC symptoms.Methods39 OCD patients (52,5% female; 19 to 64 years old) answered the Portuguese versions of the Autism-Spectrum Quotient for Adults and Obsessive Compulsive Inventory – Revised (OCI-R). Spearman correlation and linear multiple regression tests were performed using SPSS.ResultsThe OCI-R global score showed positive correlations with some AQ dimensions (attention switching, attention to detail and communication). The regression model showed that attention to detail (β = .43, p = .01) and attention switching (β = .33, p = .038) explained 36% of obsessive-compulsive symptoms variance.ConclusionsOur results are in line with a dimensional perspective of psychopathological continua and indicate that the overlap between OCD and ASD occurs through shared neurocognitive processes. We suggest that, besides being a predisposing factor for social difficulties (e.g.: facial/emotion recognition) in ASD, attention to detail and deficits in attention switching may also lead to difficulties to dismiss repetitive thoughts or extinguish behaviours in OCD. Future studies should investigate the distinctive features and underlying processes between OCD/ASD.

The OCI-12: A syndromally valid modification of the obsessive-compulsive inventory-revised

The 18-item Obsessive-Compulsive Inventory-Revised (OCI-R) is a widely used self-report measure of Obsessive-Compulsive Disorder (OCD) symptoms, yet its factor structure does not converge with contemporary dimensional models of OCD symptoms. In addition to assessing the four core OCD dimensions, the OCI-R includes hoarding and neutralizing factors. However, since its publication, hoarding has been designated as a separate disorder, and there are concerns about the neutralizing factor's reliability and validity. The aim of this study was to evaluate a syndromally valid modification of the OCI-R. Adult samples of individuals diagnosed with OCD (n = 1087), anxiety related disorders (n = 1306), and unselected community volunteers (n = 423) completed the OCI-R and measures of anxiety and mood. Analyses excluded the 3 OCI-R hoarding items and suggested the removal of the 3 neutralizing items. Internal consistency, sensitivity and specificity to OCD clinical status, test-retest reliability, sensitivity to treatment, and convergent and discriminant validity were evaluated for the resultant 12-item scale (termed the OCI-12). The OCI-12 evidenced good to excellent psychometric properties. Clinical norms, severity benchmarks, and a clinical cutoff score were computed. In conclusion, the OCI-12 represents a syndromally valid update of the OCI-R with comparable psychometric properties and superior sensitivity and specificity.

Not all personal definitions of healthy eating are linked to orthorexic behaviors among French college women. A cluster analysis study

PurposeThis study represents a first attempt to explore the typology of French female young adults based on personal definitions of healthy eating and to examine inter-group differences regarding their tendencies towards Orthorexia Nervosa (ON), eating disordered (ED) and obsessive-compulsive (OC) behaviors. Method362 female adults (Mage = 23.43, SD = 3.82) completed a 40-item questionnaire assessing personal definitions of healthy eating, the Eating Habits Questionnaire, the Eating-Disorders Inventory-3 and the Obsessive-Compulsive Inventory-Revised. ResultsExploratory factor analysis yielded 6 factors for healthy eating definitions: “Health benefits”, “Politico-ecological”, “Restriction”, “Pleasure”, “Socio-cultural” and “Dietary avoidance”. Cluster analysis based on these factors identified 3 distinct groups: “Self & Environment aware " (SEA), “Restrictive-Avoidant” (RA) and “Sociable-Pleasure seeking” (SP). The SEA cluster emphasized the “Health benefits”, “Politico-ecological” and “Dietary avoidance” factors while defining healthy eating. The RA cluster highlighted the “Restriction” and “Dietary avoidance” factors while the SP cluster mainly emphasized the “Pleasure” and “Socio-cultural” factors. Compared to all other clusters, the SEA cluster displayed greater scores in ON behaviors. The RA cluster displayed greater scores in ED behaviors compared to SP cluster. No significant difference was found between clusters regarding OC behaviors. ConclusionFindings from this study suggest that ON behaviors can vary depending on personal definitions of healthy eating. They further indicate that the definitions of healthy eating related to ON behaviors are largely different from those related to ED and OC behaviors. This study offers considerable support for the possibility of ON being a distinct condition from ED and OC behaviors.

Defining reliable change, treatment response and remission on the Florida Obsessive Compulsive Inventory

Response in the treatment of OCD has been defined by an international consensus as.≥35% reduction on a clinician rated interview, the Yale-Brown Obsessive Scale (Y– BOCS). Remission is defined as a score of ≤12 on the Y-BOCS. However, clinicians do not routinely use an observer rated scale for measuring outcomes as this requires training as well as resources to administer it. The Florida Obsessive Compulsive Inventory (FOCI) is a 5 item self-report scale that can be used for measuring change during treatment. Scores from a clinical service were used to calculate the cut-off scores for response and remission compared to the Y-BOCS and evaluated using receiver operating curves (ROC) analysis. We found that a reduction of 25% on the FOCI best corresponded to a reduction on the Y-BOCS of 35%. A score ≤7 on the FOCI at post-treatment was the optimal cut-off in determining full or partial remission from OCD. A reliable improvement was found to be a score of 6. This may assist clinicians in treatment evaluation and enable comparisons with results from clinical trials, when the Y-BOCS is not available. In a separate out-patient sample we found that the FOCI was just as sensitive to change with the same effect size as the Obsessive-Compulsive Inventory (OCI) and Obsessive-Compulsive Inventory-Revised (OCI-R). The FOCI imposes significantly less burden on clients, being only 5 items, and should be adopted more widely as an outcome measure in OCD.

The OCI-4: An ultra-brief screening scale for obsessive-compulsive disorder

Obsessive-compulsive disorder (OCD) is a prevalent and burdensome condition that is typically assessed using in-depth interviews or lengthy self-report measures. Accordingly, routine screening in busy non-mental health settings is impractical, and OCD is often under- (or mis-) recognized. We evaluated an ultra-brief version of a widely used self-report measure, the Obsessive-Compulsive Inventory-Revised (OCI-R), which may be employed as a routine screener for OCD. A total of 1087 adults diagnosed with OCD, 1306 unselected adults from the community, and 423 adults with anxiety related disorders completed the OCI-R along with measures of anxiety and mood. Analyses were conducted to reduce the number of items and examine evidence for sensitivity and specificity to OCD clinical status, test-retest reliability, sensitivity to treatment, and convergent and discriminant validity. Four items that optimally assess different dimensions of OCD (washing, checking, ordering, obsessing) were identified. Psychometric evaluation revealed good to excellent test-retest reliability, validity, prediction of clinical OCD status, and sensitivity to treatment. A 4-item version of the OCI-R, called the OCI-4, shows promise as an ultra-brief screening tool for identifying likely OCD in settings where in-depth assessment is impractical. Patients with a positive screen may be referred for further evaluation and appropriate treatment.

The reliability and validity of the Florida Obsessive-Compulsive Inventory in a Chinese clinical sample

BackgroundThe Florida Obsessive-Compulsive Inventory (FOCI) is a self-report measure designed to assess obsessive-compulsive symptom presence and severity. This study evaluated the reliability and validity of the Chinese version of the FOCI and its optimal cut-off score. MethodsA systematic translation process was used to translate the English FOCI into Chinese. Four hundred and fifty-three adults participated in the study including 153 individuals with OCD, 150 case-controls with a primary anxiety or depressive disorder, and 150 healthy controls. All three groups were evaluated by a set of measures including the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS), the FOCI, the Obsessive-Compulsive Inventory-Revised (OCI-R), the Beck Depression Inventory-Second Edition (BDI-Ⅱ), the Beck Anxiety Inventory (BAI), and the Short Form Health Survey (SF-36). Among the OCD patients, a subset of 47 participants were evaluated over a two-week interval to assess test-retest reliability of the FOCI. ResultsThe internal consistency of the FOCI Symptom Checklist and Severity Scale in the OCD group were0.813 and 0.840. Two-week test-retest reliability were 0.934 and 0.935. Convergent validity of the FOCI Symptom Checklist and Severity Scale were both strong. Correlations with diverging constructs were modest overall. Factor analysis of the FOCI Severity Scale was conducted, identifying a single factor solution explaining 62.3% of the variance. FOCI scores among those in the OCD group were higher than those from the case-control and healthy control groups. A cut-off score of 8 was optimal in predicting caseness. ConclusionsThe Chinese version of the FOCI demonstrated good psychometric properties including internal consistency, test-retest reliability, a stable factor structure, and convergent and divergent validity. A cut-off score of 8 was optimal in predicting caseness.

Students’ mental health problems before, during, and after COVID-19 lockdown in Italy

The lockdown due to the coronavirus pandemic may have exacerbated mental health problems. To what degree mental health may be affected by social isolation is still poorly known. We collected prospective data on students’ mental health in two instances: (i) in October and December 2019, and (ii) 6 months later, in April 2020 amidst the COVID-19 lockdown in Italy and in mid-May/June 2020, after the lifting of lockdown. A total of 358 Italian students aged 18–30 completed socio-demographic questionnaires and the Beck Depression Inventory – 2 (BDI-2), the Beck Anxiety Inventory (BAI), the Obsessive-Compulsive Inventory – Revised (OCI-R), the Eating Habits Questionnaire (EHQ), and the Eating Disorder Inventory-3 (EDI-3). We applied multiple regression models to evince any changes in the aforementioned questionnaire scores during and after lockdown with respect to the scores before lockdown. Students reported on average worse depressive symptoms during lockdown than 6 months before isolation (median increase in the BDI-2 score +2; IQR = −3, 6; β = 0.09 ± 0.03, p = 0.005), with students without any established diagnosis of psychopathology being affected the most. The regression models predict that 86.2% (IQR = 67.9, 91.4%) of students would not experience a clinically significant worsening of symptoms, while approximately 6% of our target population could develop more severe depressive symptoms. This study supports the view that depressive symptomatology may be aggravated during lockdown, but also highlights that after the lifting of lockdown any changes quickly vanished, as the BDI-2 scores were not different from the ones reported before lockdown.

Prevalence, sociodemographic and academic correlates of obsessive-compulsive disorder in the students of college of applied medical sciences, Umm Al-Qura university

IntroductionThe studies suggesting the prevalence of Obsessive-compulsive disorder is scant in the region of Saudi Arabia and more so in a population sample of medical and paramedical students. The aim of this study was to estimate the prevalence of obsessive-compulsive symptoms in a community sample of students of applied medical sciences. Furthermore, an association between obsessive compulsive symptoms and various sociodemographic variables and several aspects of academic life were investigated. MethodsThis cross-sectional study recruited 404 university students belonging to four departments. Tools used in the study included Obsessive compulsive inventory revised (OCI-R), DSM-IV criteria for diagnosis of OCD and Y-BOCS severity rating scale. The main outcome would be probable obsessive compulsive disorder (OCI-R score>21). The students with >21score were further evaluated for the presence of obsessive compulsive disorder using DSM-IV criteria and Y-BOCS. ResultsThe prevalence of OCS was 20% [95%CI (19.902–20.098)] with the OCI-R screening tool. Actual prevalence of confirmed OCD was 5.06% [95%CI (4.39–6.12)]. Presence of probable OCD was significantly high [p = 0.002 and 95%CI (1.31–3.53)] in students of laboratory medicine department. A significant association was found between presence of OCS and dissatisfaction with the course selection [p = 0.001, 95% CI (1.38–3.92)], feeling of rejection [p = 0.004, 95%CI (1.39–5.88)] and depressive symptoms [ p = 0.0001 and CI (1.81–4.89)]. Our sample was limited to college age women, therefore the interpretation of prevalence my not be generalizable. ConclusionThe presence of such a disorder is likely to effect academic performance, quality of life and interpersonal relationships hence, identification and treatment at the right time help improve academic performance and quality of life.

The effects of anxiety, depressive, and obsessive-compulsive subclinical symptoms on performance monitoring

Dysfunctional performance monitoring has been proposed as a potential neurocognitive biomarker of various internalising psychopathological symptoms, such as anxiety, depressive, and obsessive-compulsive symptoms. Given the overlapping neurophysiological findings and high rates of comorbidity amongst these internalising symptoms, an important research gap pertains to the specificity of performance monitoring to each of these symptoms. The aim of the present study was to examine the effects of anxiety, depressive, and obsessive-compulsive symptoms on performance monitoring in healthy adults. The sample consisted of 50 participants, with ages ranging from 18 to 33 years (M = 22.82, SD = 3.84). The Depression, Anxiety, and Stress Scales-21 and the Obsessive Compulsive Inventory-Revised were administered to assess the various internalising symptoms. An arrow flanker task was administered to elicit error responses whilst electrophysiological data were recorded from the scalp. Performance monitoring was indexed by the error-related negativity and correct response negativity. Bivariate correlations revealed that the three internalising symptoms were not associated with error-related negativity or correct response negativity amplitudes. However, a regression model revealed that greater levels of anxiety symptoms were uniquely associated with larger error-related negativity amplitude after controlling for depressive symptoms. In addition, greater levels of depressive symptoms were uniquely associated with smaller error-related negativity amplitude. Another regression model revealed that greater levels of depressive symptoms were uniquely associated with smaller correct response negativity amplitude after controlling for anxiety symptoms. These findings suggest that performance monitoring differentially associates with anxiety and depressive symptoms amongst healthy adults, providing some evidence of specificity for each respective symptoms.

The Obsessive-Compulsive Inventory-Revised: Replication of the psychometric properties in China.

The aim of this study is to replicate the findings from previous research about the psychometric properties of the Mandarin Chinese version of the Obsessive-Compulsive Inventory-Revised (OCI-R), which assesses the presence of symptoms obsessive-compulsive disorder and the distress associated with those symptoms. The final clinical sample included 80 participants from multiple psychiatric outpatient clinics in China. Participants completed the following questionnaires: the OCI-R, the Depression, Anxiety, and Stress Scale (DASS-21), the Yale-Brown Obsessive-Compulsive Scale-II (Y-BOCS-II), and the Clinical Global Impressions Scale, Severity (CGI-S). The Mandarin Chinese version of the OCI-R demonstrated good internal consistency for the total scale and each subscale. Good convergent and divergent validity was established. The Mandarin Chinese version of the OCI-R demonstrated good psychometric properties. Further research is needed to examine the factor structure of the Chinese version of the OCI-R and the extent to which it aligns with the original version.

Schizotypal and obsessive-compulsive traits: Co-occurrence rate and relationship with executive function, emotion experience, and emotion expressivity in college students.

Empirical findings suggest that there is an overlap between schizophrenia and obsessive-compulsive disorder (OCD). These disorders also have a high comorbidity rate. However, little is known about the impact of co-occurring schizotypal and obsessive-compulsive traits on executive function, emotion experience, and emotion expressivity in the normal population. The present study examined the prevalence of coexisting schizotypal and obsessive-compulsive traits and the relationship between these two traits in a sample of healthy college students. We also conducted a moderation analysis to explore the effect of these two type of traits on executive function, emotion experience, and emotion expressivity. We recruited 3,319 participants to complete the Schizotypal Personality Questionnaire (SPQ) and the Obsessive-Compulsive Inventory - Revised (OCI-R). A subset of them (n = 575) also completed the Chinese versions of the Dysexecutive Questionnaire (DEX), the Temporal Experience of Pleasure Scale (TEPS), and the Emotional Expressivity Scale (EES). We found that the prevalence of co-occurring schizotypal and OCD traits was 3.33%. All the subscales of the SPQ and the OCI-R significantly correlated with each other. Both traits had a negative impact on executive function and emotion expressivity. The interaction between the disorganization dimension of schizotypal traits and OCD traits had a significant effect on executive function, but not emotion experience or emotion expressivity. This study was limited by its cross-sectional design and recruitment of only college students. These findings suggest that there is an approximately 3% rate of co-occurring schizotypal and obsessive-compulsive traits in a healthy college student sample. The interaction between these two types of traits may influence executive function.
