Compulsive Subscale Research Articles

The Relationship between Parents' Use of the Pediatric Emergency Department and Cyberchondria.

The study aimed to investigate the correlation between children's attendance at the emergency department and the cyberchondria of parents. The population for this cross-sectional study comprised parents of children aged 0 to 18 attending the emergency department. Research data were collected using an Information Form, the Cyberchondria Severity Scale (CSS). The participants had mean CSS scores of 41.45 ± 19.22. There were significant differences observed between the reason for choosing the emergency department with mean scores for the total CSS (F = 2.289, P = .021), distress (F = 2.466, P = .013), and compulsion (F = 2.822, P = .005) subscales. A weak positive correlation was identified between the number of attendances at the emergency department in the last year and the excessiveness (r = .204) subscale. Participants had moderate levels of CSS. According to the research findings, most parents attended the emergency department for non-urgent reasons. In addition, as the cyberchondria severity level of parents increased, their attendance at health institutions and emergency departments was determined to increase.

Brief Assessment Tools for Obsessive Compulsive Disorders in Children: A Systematic Review.

Children and adolescents with suspected obsessive-compulsive disorder (OCD). To estimate the comparative performance of brief diagnostic assessment tools. PubMed, the Cochrane Register of Clinical Trials, the Cochrane Database of Systematic Reviews, Embase, CINAHL, PsycINFO, and ERIC, and for unpublished studies with reported results in ClinicalTrials.gov through May 15, 2024. Studies of children (up to age 21) with a clinical suspicion of OCD that evaluated the accuracy (predictive validity) of brief assessment tools for OCD, compared to a reference standard. We extracted participant characteristics, scale and reference standard information, results, and risk of bias assessment. We performed random-effects diagnostic meta-analysis where feasible. We assessed strength of evidence for each scale. There is moderate strength of evidence that the 8-question version of the Child Behavior Checklist-Obsessive Compulsive subscale is sufficiently sensitive and specific (summary area under the curve of 0.84, 95% CI 0.74 to 0.91) to prompt specialist referral for additional diagnostic assessment. Other tools may perform as well or better, but the current evidence is insufficient to justify broad conclusions about their performance. Few studies per scale, case-control studies, and homogenous White populations may preclude generalizability of tool performance. Based on the current evidence the CBCL-OCS probably is sufficiently accurate to indicate which youth should be further evaluated for OCD, but further research is needed to establish that the 8-question subscale can function as a stand-alone measure. The available evidence is insufficient for other brief assessment tools.

Reduced resting-state functional connectivity of default mode network subsystems in patients with obsessive-compulsive disorder

ObjectivesNeuroimaging studies have reported extensive resting-state functional connectivity (rsFC) abnormalities in the default mode network (DMN) in patients with obsessive-compulsive disorder (OCD), but findings are inconsistent. DMN can be divided into three subsystems: core, dorsal medial prefrontal cortex (dMPFC), and medial temporal lobe (MTL). This study aimed to explore abnormalities in rsFC strength within and between DMN subsystems in OCD patients, and their relationship with clinical symptoms. MethodsThis study recruited 39 OCD patients and 45 healthy controls (HCs). OCD symptoms were assessed using the Yale-Brown Obsessive-Compulsive Scale (YBOCS). The seed-to-seed method was used to construct rsFC matrix. The rsFC strength within and between the three DMN subsystems were calculated. ResultsCompared to the HC group, the OCD group exhibited reduced rsFC strength within core subsystem (F = 7.799, p = 0.007, Bonferroni corrected p = 0.042). Further, this reduction was also observed in the unmedicated OCD group (n = 19), but not in the medicated OCD group (n = 18). In addition, rsFC strength within core subsystem was negatively correlated with the obsession subscale of YBOCS in the OCD group (r = −0.512, p = 0.004, Bonferroni corrected p = 0.008). Further, this correlation was also significant in the unmedicated OCD group, but not in the medicated OCD group. ConclusionsOur findings suggest that reduced rsFC strength within core subsystem is a feature of OCD patients and may serve as a potential biomarker of obsession severity. Moreover, pharmacological treatments may affect rsFC strength in DMN.

Naproxen adjunct to fluoxetine for moderate-to-severe obsessive-compulsive disorder: A randomized, double-blind, placebo-controlled trial.

Current treatments for obsessive-compulsive disorder (OCD) encounter resistance and limiting adverse events, necessitating novel therapeutic strategies. This study aimed to investigate the benefits of naproxen, a medication with effects on inflammation and neuronal function, on OCD. One hundred and four OCD outpatients with a Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) score of >21 were equally assigned to receive fluoxetine plus either naproxen 250 mg or matched placebo q12hr. Patients were assessed using the Y-BOCS by recording the subscale scores at baseline and weeks 5 and 10 to evaluate efficacy. They were also assessed in terms of tolerability. Data from 96 patients were analyzed. The baseline characteristics were comparable between the groups. There were significant time-treatment interaction effects on the obsession subscale ( = 0.055) and total ( = 0.043) scores of Y-BOCS. Reductions in the obsession subscale and total scores of Y-BOCS were significantly greater in the fluoxetine plus naproxen group until the endpoint (Cohen's d = 0.560 and Cohen's d = 0.477, respectively). However, the difference in compulsion subscale score changes between the groups was not significant. Respondents with a reduction of ≥35% in Y-BOCS total scores were significantly more in the fluoxetine plus naproxen group (80.0% versus 47.8%). The side effect frequencies were comparable between the groups. Naproxen, adjunct to fluoxetine, outperformed adjunctive placebo in treating obsession and total symptoms of OCD patients in a safe and tolerable manner. The study protocol was registered and published in the Iranian Registry of Clinical Trials (http://www.irct.ir; registration number IRCT20090117001556N139).

Metaanalysis of Repetitive Transcranial Magnetic Stimulation (rTMS) Efficacy for OCD Treatment: The Impact of Stimulation Parameters, Symptom Subtype and rTMS-Induced Electrical Field.

Background: Repetitive transcranial magnetic stimulation (rTMS) has recently demonstrated significant potential in treating obsessive-compulsive disorder (OCD). However, its effectiveness depends on various parameters, including stimulation parameters, OCD subtypes and electrical fields (EFs) induced by rTMS in targeted brain regions that are less studied. Methods: Using the PRISMA approach, we examined 27 randomized control trials (RCTs) conducted from 1985 to 2024 using rTMS for the treatment of OCD and conducted several meta-analyses to investigate the role of rTMS parameters, including the EFs induced by each rTMS protocol, and OCD subtypes on treatment efficacy. Results: A significant, medium effect size was found, favoring active rTMS (gPPC = 0.59, p < 0.0001), which was larger for the obsession subscale. Both supplementary motor area (SMA) rTMS (gPPC = 0.82, p = 0.048) and bilateral dorsolateral prefrontal cortex (DLPFC) rTMS (gPPC = 1.14, p = 0.04) demonstrated large effect sizes, while the right DLPFC showed a significant moderate effect size for reducing OCD severity (gPPC = 0.63, p = 0.012). These protocols induced the largest EFs in dorsal cognitive, ventral cognitive and sensorimotor circuits. rTMS protocols targeting DLPFC produced the strongest electrical fields in cognitive circuits, while pre-supplementary motor area (pre-SMA) and orbitofrontal cortex (OFC) rTMS protocols induced larger fields in regions linked to emotional and affective processing in addition to cognitive circuits. The pre-SMA rTMS modulated more circuits involved in OCD pathophysiology-sensorimotor, cognitive, affective, and frontolimbic-with larger electrical fields than the other protocols. Conclusions: While rTMS shows moderate overall clinical efficacy, protocols targeting ventral and dorsal cognitive and sensorimotor circuits demonstrate the highest potential. The pre-SMA rTMS appears to induce electrical fields in more circuits relevant to OCD pathophysiology.

Prevalence of phubbing behaviour in school and university students in Spain.

This study examined the prevalence of phubbing behavior among school and university students in Spain and analyzed the correlation of phubbing with other indicators of psychological well-being and mental health. The study sample comprised a total of 1,351 school and university students, with ages ranging from 12 to 21 years. The study used the Phubbing Scale (PS), the Compulsive Internet Use Scale (CIUS), the Rosenberg Self-Esteem Scale (RSE), and the Interpersonal Emotion Regulation Questionnaire (IERQ) for data collection. The results showed evidence of phubbing among approximately half of the students. Statistically significant differences were found based on gender and educational level in the Phone Obsession subscale and the PS total score, with male students and university students scoring higher in their respective parameters. In addition, phubbing was positively correlated with problematic internet use and negatively correlated with self-esteem. Phubbing behavior is highly prevalent among adolescents aged 12-21 years and is positively correlated with low self-esteem and problematic internet use. Developing strategies for addressing this widespread issue at early ages, particularly within the educational context, such as schools, is crucial for implementing preventive measures. The inappropriate use of technological devices, including smartphones, in schools has the potential to negatively affect students' well-being and ability to adapt to school.

Cognitive Impulsivity in Anorexia Nervosa in Correlation with Eating and Obsessive Symptoms: A Comparison with Healthy Controls.

Impulsivity in eating disorders (ED) has been historically focused on bingeing-purging symptoms, evidencing lower levels in restricting subtypes. In the recent literature, obsessive-compulsive disorder (OCD) has been described as characterized by high cognitive impulsivity. This specific impulsivity factor has been rarely studied in anorexia nervosa (AN). In this study, 53 inpatients with anorexia nervosa and 59 healthy controls completed the following questionnaires: the Barratt Impulsiveness Scale (BIS-11), the Obsessive-Compulsive Inventory (OCI), the Eating Disorders Inventory-2 (EDI-2), the State-Trait Anxiety Inventory (STAI), and the Beck Depression Inventory (BDI). AN individuals showed significantly increased levels of cognitive instability but no difference in global score and other subscales of impulsivity compared to the healthy controls. Among AN individuals, cognitive instability emerged as being associated with the global score and obsession subscale of the OCI. It was also significantly associated with interoceptive awareness and impulse regulation. Cognitive instability was the main predictor of obsessive thoughts and behaviors in AN. Our study supports the hypothesis of AN as being characterized by high cognitive instability and adds the result that the cognitive domain of impulsivity may be associated with the presence of obsessive symptoms, specifically obsessive thoughts.

Validation of the Chinese Version of Penn Alcohol Craving Scale for Patients With Alcohol Use Disorder.

The Penn Alcohol Craving Scale (PACS) is a five-item, single-dimension questionnaire that is used to measure a patient's alcohol craving. We sought to develop the Chinese version of the PACS (PACS-C) and assess its reliability and validity. A total of 160 Taiwanese patients with alcohol use disorder were enrolled in this study. The internal consistency and concurrent validity of the PASC-C with the visual analogue scale (VAS) for craving, the Yale-Brown Obsessive Compulsive Scale for heavy drinking (YBOCS-hd), and the Severity of Alcohol Dependence Questionnaire (SADQ) were assessed. The test-retest reliability of the PASC-C was evaluated 1 day after the baseline measurements. Confirmatory factor analysis (CFA) was performed to examine the psychometric properties of the PACS-C. The PACS-C exhibited good internal consistency (Cronbach's α=0.95) and test-retest reliability (r=0.97). This scale showed high correlations with the VAS (r=0.81) and YBOCS-hd (r=0.81 and 0.79 for the obsession and compulsion subscales, respectively), and moderate correlation with the SADQ-C (r=0.47). Furthermore, CFA results revealed that the PACS-C had good fit indices under various models. The PACS-C appears to be a reliable and valid tool for assessing alcohol craving in patients with alcohol use disorder in Taiwan.

Mothers with Dysregulated Eating and Their Offspring's Emotional/Behavioral Functioning during the COVID-19 Pandemic: A Descriptive Study.

Research on the psychopathological effects of the COVID-19 pandemic has not specifically focused on mothers with dysregulated eating and their children. This study aimed to observe whether the symptoms of mothers with binge eating episodes (assessed through the SCL-90/R and the TFEQ-R18) worsened from the pre-pandemic period (T1) to the pandemic period (T2). In addition, we sought to assess whether the levels of internalizing/externalizing and dysregulation symptoms in children (assessed through the CBCL 6-18) worsened from T1 to T2. Our results showed that the values obtained for mothers in the SCL-90/R were significantly higher at T2 (during the pandemic), particularly for Depression, Phobic Anxiety, Interpersonal Sensitivity, and Obsessive-Compulsive subscales. Moreover, in both the Emotional Eating and Uncontrolled Eating subscales of the TFEQ-R18, mothers at T2 scored substantially higher than mothers at T1. The emotional/behavioral functioning of children was more maladaptive at T2, according to mothers, especially for the subscales of Withdrawn, Anxious/Depressed, and Aggressive Behavior. Children also had significantly higher scores on the Internalizing and Externalizing subscales, as well as greater symptoms of dysregulation. This study contributes to demonstrating that the COVID-19 pandemic may have had increased maladaptive emotional/behavioral functioning in children and their mothers with dysregulated eating.

Silent Infections are not So Silent: The Emerging Role of Combined Infections, Inflammation, and Vitamin Levels in OCD.

Recent evidence highlights that different agents may trigger immune-mediated processes involved in the pathophysiology of different neuropsychiatric conditions. Given the limited information on obsessive-compulsive disorder (OCD), the present study aimed at assessing current/past infections and plasma levels of vitamin D, vitamin B12, folic acid, homocysteine and common peripheral inflammatory markers in a group of OCD outpatients. The sample included 217 adult outpatients with an OCD diagnosis according to the DSM-5 criteria. The Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) was used to assess the clinical phenotype and symptom severity. Laboratory blood tests measured levels of vitamin D, vitamin B12, folic acid, homocysteine, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), blood count and antibodies titers for cytomegalovirus (CMV), Epstein Barr virus (EBV), Toxoplasma gondii and antistreptolysin titer. Sixty-one patients had a previous EBV infection, 46 were seropositive for CMV IgG, 24 showed positive antistreptolysin titer, 14 were seropositive for Toxoplasma gondii IgG, and four for CMV IgM. More than a half of patients showed vitamin D insufficiency. Compared to seronegative patients, patients with a past EBV infection displayed significantly higher scores on the Y-BOCS total score and compulsion subscale, and other symptoms. Vitamin D was negatively correlated with both the Y-BOCS total score and the subscales scores. Folic acid was negatively correlated with the Y-BOCS total and obsessions subscale score. The findings of our study show an association between Epstein-Barr infection and hypovitaminosis D and the overall severity and specific symptom patterns of OCD. The laboratory measures used in this study are useful, cheap and easy parameters that should be routinely assessed in patients with OCD. Further studies are needed to clarify their role in OCD pathophysiology and outcomes, as well as the potential therapeutic impact of vitamins and antibiotics/immunomodulatory agents in OCD and other psychiatric conditions.

Regional homogeneity in patients with obsessive–compulsive disorder and depression: A resting state functional magnetic resonance imaging study

ObjectiveTo explore the brain functional impairment of patients with obsessive–compulsive disorder (OCD) with and without depressive symptoms and analyze the correlation between the degree of impairment and the severity of symptoms. MethodFourteen patients with OCD who met the ICD-10 diagnostic criteria for OCD were included. The group having OCD with depression (OCDd) consisted of 15 patients, and 17 healthy controls (HC) matched for age and education were also included. The Yale–Brown OCD Scale (Y-BOCS) and the 24-item Hamilton Assessment of Depression Scale (HAMD) were administered to the OCD and OCDd groups. Resting-state functional brain magnetic resonance imaging was performed in the three groups of participants. ResultThe OCDd group had lower scores on the HAMD, Y-BOCS, and obsessive–compulsive thinking subscales compared with the OCD group (P < 0.05). The scores on the OCDd subscale were negatively correlated with the HAMD scores (R = − 0.568, P = 0.027). The OCDd group had higher regional homogeneity (ReHo) values in the lingual gyrus than the OCD group. The OCDd group had higher ReHo values in the lingual gyrus than the HC group, and the OCDd group had higher ReHo values than the HC group. These differences were statistically significant (P < 0.05). After correction for multiple comparisons, significant difference was observed between the OCDd and HC groups (P＜0.05). In the OCD group, the ReHo value of the lingual gyrus was negatively correlated with the Y-BOCS total score and the compulsive behavior subscale score (R = − 0.609, −0.552; P = 0.016, 0.033). ConclusionAbnormal ReHo values in the lingual gyrus and right medial superior frontal gyrus were found in the patients with OCDd. In the OCDd group, the ReHo values of the lingual gyrus were negatively correlated with the scores on the Y-BOCS total and obsessive–compulsive subscales, suggesting that abnormal local coherence of the lingual gyrus may be related to the severity of OCD.

Agomelatine augmentation of sertraline in the treatment of moderate to severe obsessive-compulsive disorder: a randomized double-blinded placebo-controlled clinical trial

BackgroundAs 40–60% of the patients with obsessive-compulsive disorder (OCD) do not adequately respond to the first-line treatment, finding an effective second-line treatment is required. Our aim was to assess the efficacy and safety of agomelatine (a selective melatonin receptor agonist and a 5-hydroxytryptamine (HT)2 C antagonist) augmentation of sertraline in the treatment of patients with moderate to severe OCD.MethodsIn this 12-week randomized, double-blinded, placebo-controlled, parallel-group clinical trial, 65 patients with moderate to severe OCD according to the Diagnostic and Statistical Manual of Mental Disorders-Fifth edition (DSM–5) criteria and a Yale-Brown obsessive compulsive scale (Y-BOCS) score of over 21, were included. They were assigned with sertraline (100 mg/day for the first 4 weeks and 200 mg/day for the next 8 weeks) and either agomelatine (25 mg/day) or placebo. The primary outcome was OCD symptoms measured by the Y-BOCS.ResultsFifty patients (24 in agomelatine group and 26 in placebo group) completed the trial. The Y-BOCS scores in total (MD (95% CI) = 12.25 (11.00, 13.49) (P < 0.001) vs. MD (95% CI) = 12.46 (6.65, 15.74) (P < 0.001)), the obsession subscale (MD (95% CI) = 5.04 (4.19, 5.88) (P < 0.001) vs. MD (95% CI) = 5.00 (3.84, 6.16) (P = 0.0001)), and compulsion subscale (MD (95% CI) = 7.21 (6.34, 8.07) (P < 0.001) vs. MD (95% CI) = 7.460 (6.50, 8.42) (P < 0.001)) significantly decreased in both groups. Although, at the end of the trial, no significant difference was observed between the scores of the two groups in total (MD (95% CI) = 0.480 (-1.23, 2.19) (P = 0.78)), the obsession subscale (MD (95% CI) = 1.020 (-0.15, 2.19) (P = 0.38)), and the compulsion subscale (MD (95% CI) = 0.540 (-0.34, 1.42) (P = 0.54)). No major adverse effects were recorded, and the frequency of side effects was not significantly different between the groups.ConclusionAgomelatine in augmentation with sertraline is safe and tolerable in patients with moderate to severe OCD. However, our study does not support its efficacy in improving OCD symptoms, compared to placebo.Trial registrationThe trial was registered at the Iranian Registry of Clinical Trials on 14/07/2020 (www.irct.ir; IRCT ID: IRCT20170123032145N5).

Examination of the Differences in Licensed Athletes’ Personal Beliefs in Relation to Some Socio-demographic Characteristics

Objective: This study was carried out to examine the personality beliefs of licensed athletes according to sports branch, type of sport and gender. In addition, it is aimed to make some contributions to the literature since personality beliefs in athletes have not been studied before. Methods: This study was conducted by using the survey model. The study group consisted of 154 licensed athletes aged 15 and over. A Personal Information Form and the Personality Belief Scale Short Form were used to collect data in the study. SPSS 22.0 package program was used in the analysis of the data. Results and Suggestions: When the personality beliefs of licensed athletes were examined according to the sports branch variable, no significant difference was found in the sub-dimensions of schizoid, paranoid and antisocial personality beliefs. Narcissistic, histrionic, and borderline sub-dimensions scores were found to vary significantly. When examined according to the variables of doing team sports or individual sports, no significant difference was found between these two groups in all the personality belief sub-dimensions. When examined according to the gender variable, only the obsessive/compulsive subscale scores were found to vary significantly depending on gender in favour of the male athletes. Comparing personality beliefs with those who do not do sports can be useful in determining whether doing sports is effective in personality beliefs. Examining the personality beliefs of athletes according to their success can contribute to the field of sports and exercise psychology.

Reboxetine Combination Therapy With Fluoxetine in Moderate to Severe Obsessive-Compulsive Disorder: A Placebo-Controlled, Double-Blind, Randomized Trial.

Reboxetine is a potent and selective norepinephrine reuptake inhibitor that was effective in combination with citalopram for resistant obsessive-compulsive disorder (OCD). This study aims to assess its effectiveness and tolerability in combination with fluoxetine in treating OCD. In this 2-center, placebo-controlled, and double-blind, randomized clinical trial, 76 patients with OCD were assigned into 2 parallel groups to receive fluoxetine (up to 80 mg/d) plus placebo (F + P) or fluoxetine (up to 80 mg/d) plus reboxetine (F + R) (10 mg twice daily) for 10 weeks. Participants were assessed with the Yale-Brown Obsessive Compulsive Scale (Y-BOCS) at baseline and weeks 5 and 10. A total of 76 patients completed the trial. There was no significant difference between the 2 groups in baseline Y-BOCS scores. General linear model repeated-measures showed significant effects on time × treatment interaction on total Y-BOCS ( F = 6.33, df = 1.42, P = 0.006) and obsession subscale scores ( F = 10.39, df = 1.48, P < 0.001), and insignificance on compulsion subscale scores ( F = 1.86, df = 1.24, P = 0.173). Reboxetine combination therapy demonstrated a higher partial and complete treatment response rate ( P < 0.01) according to the Y-BOCS total scores. There was no significant difference between the 2 groups in the frequency of adverse effects. Reboxetine combination therapy with fluoxetine can effectively improve symptoms in patients with OCD in a short period of treatment. However, further studies with larger sample sizes and longer follow-up periods are needed to confirm these findings.This trial was registered with the Iranian Registry of Clinical Trials ( www.irct.ir ; No IRCT20090117001556N129).

L-theanine combination therapy with fluvoxamine in moderate-to-severe obsessive-compulsive disorder: a placebo-controlled, double-blind, randomized trial.

The main aim of this study was to investigate the additional effects of L-theanine, an amino acid in tea and an analog of glutamate with neuroprotective and anti-depressant properties, on obsessive-compulsive disorder (OCD) symptoms in combination with fluvoxamine. Patients from either sex aged between 18-60 years diagnosed with OCD, based on the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), who had a Yale-Brown Obsessive Compulsive Scale (Y-BOCS) score of more than 21 were enrolled in a double-blinded, parallel-group, placebo-controlled, clinical trial of 10 weeks to receive either L-theanine (100 mg twice daily) and fluvoxamine (100 mg daily initially followed by 200 mg daily after week 5) or placebo and fluvoxamine. The primary outcome of interest in this study was the Y-BOCS total score decrease from baseline. From a total of 95 evaluated patients, 50 completed our study; 30 were randomly assigned to each group. Multivariate analysis (ANOVA) showed a significant effect of time × treatment for L-theanine in obsession subscale (F = 5.51, p-value = 0.008) of the Y-BOCS score but not in the total and compulsion scores. Our results showed significantly more improvement in obsession subscale scores in L-theanine compared to placebo group (p = 0.007, Cohen's d = 0.82). Also, total Y-BOCS scores were lower in L-theanine compared to placebo group at week 5 (p = 0.039, Cohen's d = 0.60) and 10 (p = 0.008, Cohen's d = 0.80). However, there was no significant between-group differences in compulsion subscale scores. Complete response was also more frequent in the L-theanine group (p = 0.0001). Findings in this study suggest L-theanine as a relatively safe and effective adjuvant therapy for moderate to severe OCD. This article is protected by copyright. All rights reserved.

Error-related brain activity associated with obsessive-compulsive symptoms in youth.

Subclinical obsessive-compulsive symptoms (OCS) are common in children, and increase risk for later onset of obsessive-compulsive disorder (OCD). In pediatric patients with OCD, neuroimaging research implicates altered neural mechanisms for error-processing, but whether abnormal brain response occurs with subclinical OCS remains poorly understood. Using functional magnetic resonance imaging (fMRI), 113 youth (8-18 years; 45 female) from a community sample were scanned during an error-eliciting Go/No-Go task. OCS were assessed dimensionally using the obsessive-compulsive subscale of the Child Behavior Checklist. The association between OCS scores and error-related brain activity was examined at the whole-brain level. Lower OCS scores associated with stronger response to errors in dorsal anterior cingulate cortex (dACC), caudate, putamen, thalamus, and occipital cortex. Additionally, lower OCS related to higher capacity for inhibitory control, as indexed by greater accuracy on No-Go trials during fMRI scanning. The relationship between lower OCS and better accuracy on No-Go trials was mediated by greater error-related dACC activity. The inverse relationship between OCS and error-related activity in the dACC and extended cortical-striatal-thalamic circuitry may index an adaptive process by which subclinical OCS are minimized in youth. Further, these results identify an observable pattern of brain activity that tracks with subclinical OCS severity. Understanding the link between neural networks for error processing and the normal to abnormal range of OCS may pave the way for brain-based strategies to identify children who are more likely to develop OCD and enable the targeting of preventive strategies to reduce risk.

Memantine augmentation of sertraline in the treatment of symptoms and executive function among patients with obsessive-compulsive disorder: A double-blind placebo-controlled, randomized clinical trial

IntroductionMedications currently recommended for the treatment of Obsessive-Compulsive Disorder (OCD) usually decrease the severity of the symptoms by 20–30%; however, 40–60% of OCD patients do not achieve a satisfactory response. Our main objective was to investigate the effectiveness of memantine, a non-competitive N-Methyl-D-aspartate (NMDA) receptor antagonist, as an adjunct therapy to sertraline, a selective serotonin reuptake inhibitor (SSRI), to improve severity of symptoms and executive function among patients with obsessive-compulsive disorder.ObjectivesOur main objective was to investigate the effectiveness of memantine, a non-competitive N-Methyl-D-aspartate (NMDA) receptor antagonist, as an adjunct therapy to sertraline, a selective serotonin reuptake inhibitor (SSRI), to improve severity of symptoms and executive function among patients with obsessive-compulsive disorder.MethodsSeventy patients with OCD according to the Diagnostic and Statistical Manual of Mental Disorders (DSM–5) criteria, and a Yale-Brown obsessive compulsive scale (Y-BOCS) score of more than 21 were recruited to the study. They received sertraline (100 mg daily initially followed by 200 mg daily after week 4) and either memantine (10 mg twice daily) or placebo in a placebo controlled, double-blinded, parallel-group, clinical trial of 12 weeks. The primary outcome was OCD symptoms measured by the Y-BOCS. Moreover, executive function of participants was measured by the Wisconsin Card Sorting Test (WCST).ResultsThe total score, and obsession and compulsion subscales of Y-BOCS significantly dropped in both groups with no significant difference between the two groups. However, memantine group showed a greater response in the number of completed categories subscale of the WCST (p value&lt;0.001). We did not observe any major adverse effects in any of the groups.Image:Image 2:Image 3:ConclusionsMemantine has an acceptable safety and tolerability in patients with OCD and might have a positive effect on their executive function.

Investigating the Potential Connection Between Cyberchondria and Vaccine Hesitancy in High School Students.

Internet use, which provides the opportunity to access information from anywhere, and anytime, is increasing among adolescents and young adults. In studies examining the effect of technology use in adults, it has been observed that there is a relationship between cyberchondria and vaccine hesitancy. This study aimed to uncover the potential relationship between cyberchondria and vaccine hesitancy in adolescents and to obtain data for combating anti-vaccination in this age group. A total of 2.353 high school students were enrolled within the scope of this research. The forms were delivered to the students online and 531 volunteers participated in the survey. The Cyberchondria Severity Scale and Vaccine Hesitancy Scale were used to evaluate the details of the relationship between cyberchondria and vaccine hesitancy levels in adolescents. The compulsion subscales of the Cyberchondria Severity Scale in males and vaccine repugnance subscales of the Vaccine Hesitancy Scale in females were statistically significantly higher. Cyberchondria and vaccine hesitancy have a strong relationship with each other except benefits and protective value of vaccines subscale of vaccine hesitancy. Health policymakers should be aware of this relationship and there is a need to develop novel online intervention programs for combating anti-vaccination, particularly among cyberchondriac adolescents who have relatively high vaccination hesitancy, particularly during the pandemic.

Repetitive Eating Questionnaire: Reliability and Validity of Turkish Version and Correlates of Grazing Behavior

Objectives: Grazing behaviour which is defined as repetitive and unplanned eating behaviour with small amounts of food over a period of time , has been increasingly recognised among people with obesity and eating disorders, as well as in the general population The Repetitive Eating Questionnaire (Rep(eat)-Q) is a 12 item self-report scale which was designed to measure the grazing behaviour. It demonstrating a compulsive and non-compulsive forms of grazing in previous studies. The aim of the present study was to assess the validity and reliability of the Turkish version Rep(eat)-Q in a community sample from Turkey. Method: Permission was taken from the designer of the measure . Ethical approval was granted from the local ethic Committee. The Turkish version was developed by translation and back-translation and the opinion from the local experts were obtained. The Rep(eat)-Q along with a purpose-designed socio-demographic form and other self-report measures (SCOFF eating questionnaire,, Yale Food Addiction Scale, Eating Disorder Examination Questionnaire ) were administered online to 263 of people from a convenient sample using a snowball technique. Internal consistency, convergent and divergent validity were calculated. Confirmatory factor analyses were also conducted for the factor structure. Results: The mean age of participants were 34.4 with 77.2 % female and mean body mass index (BMI) of 24.7. As in the original scale, the fit of the two-factor structure (compulsive grazing and repetitive eating) was analysed by Confirmatory factor analysis (CFA). CFA showed that the Turkish version had a two-dimensional structure as with the original form and indicated good fit (ε2 = 122, df = 48, ε2 / df = 0.77; RMSEA = 0.973; CFI = 0.962; TLI = 0.981; SRMR = 0.028). In our study, positive and moderately significant correlation between BMI and Rep(eat)-Q compulsive subscale was found; no significant correlation was found between the repetitive subscale and the BMI (r= 0.156; p=0.07). The Rep(eat)-Q scales showed excellent internal consistency both for the whole scale and the two subscales (total score Cronbach's alpha 0.947; compulsive grazing Cronbach's alpha 0.931; repetitive eating Cronbach's alpha 0.916). Conclusions: The results of this study suggest that Turkish version of Rep(eat)-Q seems to be a valid and reliable tool in assessing grazing behaviour in a non-clinical Turkish sample . It also confirmed the proposed two factor structure ( compulsive and non-compulsive) supporting the two subtypes of grazing behaviour.. Further studies are needed to assess its validity and reliability in clinical subgroups.

Obsessive-compulsive, harm-avoidance and persistence tendencies in patients with gambling, gaming, compulsive sexual behavior and compulsive buying-shopping disorders/concerns

Background and aimsThere is a growing interest in determining the specific role of obsessive–compulsive features in different behavioral addictions. However, more studies comparing sizable clinical populations with different addictions are needed.Therefore, a main aim of the present study was to explore the presence of obsessive–compulsive features among people with different behavioral addictions (gambling disorder, internet gaming disorder, compulsive sexual behavior disorder and compulsive buying-shopping concerns). Through a clustering procedure, the existence of empirical clusters among treatment-seeking patients based on obsessive–compulsive measures was explored. Materials and methodsThe Symptom Checklist-Revised, and the Temperament and Character Inventory-Revised were obtained from 4,010 treatment-seeking patients. Obsessive-compulsive features were measured with the obsessive–compulsive subscale of the Symptom Checklist-Revised and the harm avoidance and persistence dimensions of the Temperament and Character Inventory-Revised. Cluster analysis was applied to explore the existence of empirical groups based on obsessive–compulsive features. ResultsPatients with compulsive sexual behavior disorder and compulsive buying-shopping disorder reported the highest scores on the obsessive–compulsive subscale, while patients with gambling disorder showed the lowest scores on harm avoidance, and patients with internet gaming disorder the lowest scores on persistence. Two mutually exclusive clusters were identified. Cluster 1 exhibited a more maladaptive psychopathological and personality profile than cluster. Discussion and ConclusionsThese results provide new evidence regarding obsessive–compulsive features in specific behavioral addictions. Therapeutic approaches should consider that different addictions may present distinct levels of obsessive–compulsive features.
