The relationship between self-control and obsessive-compulsive symptoms: the chain mediating effect of procrastination and anxiety / 中华行为医学与脑科学杂志

Objective:To investigate the relationship between self-control and obsessive-compulsive symptoms(OCS), and the mediating role of procrastination and anxiety in this relation.Methods:Totally 6 367 Chinese college students were recruited to complete the Chinese version of the self-control scale, the Aitken procrastination inventory, and the symptom checklist-90.Descriptive analysis and Pearson correlation were carried out using SPSS 23.0.Mplus 7.4 was used to test the model fit.The mediating effects were tested using the Bootstrap method.Results:Pearson correlation analysis showed that there were significant correlations among self-control, procrastination, anxiety, and obsessive-compulsive symptoms ( r=-0.71-0.78, P<0.01). Mediation modeling analysis showed that the total indirect effect of self-control on OCS was -0.303, accounting for 63.13% of the total effect.The mediating effect of procrastination between self-control and OCS was -0.045, accounting for 9.38% of the total effect.The mediating effect of anxiety between self-control and OCS was -0.239, accounting for 49.79% of the total effect.Moreover, the chain mediating effect of procrastination and anxiety between self-control and OCS was also significant, with an effect value of -0.019, accounting for 3.96% of the total effect. Conclusion:Self-control can negatively predict OCS, procrastination and anxiety play a chain mediating role in the effect of self-control on OCS.

Introduction: the aim of this study is to describe the occurrence of symptoms of GAD and OCD in adolescents, aged between 11 to 18 years old, from a public school in the city of Salvador. Methodology: observational and cross-sectional study with 674 adolescents from a public school, who responded to a scale for assessing symptoms of GAD and OCD applied from March to December 2015. Results: the RCADS scores for GAD and OCD were on average higher than the cutoff points established by the scale, suggesting an increased presence of these symptoms in the studied population, with a higher prevalence among girls in the two groups of symptoms studied. Conclusion: data point to the presence of symptoms of generalized anxiety and OCD among schoolchildren, suggesting a greater need for studies to understand the role of these symptoms in the quality of life of this population, as well as their importance as risk factors for mental illness. Prevention measures should direct efforts towards more methodologically robust studies in the area.

Relationship between obsessive beliefs and obsessive-compulsive symptoms in medical college students / 预防医学

Objective@#To investigate the relationship of obsessive beliefs and obsessive-compulsive symptoms in medical students and to provide evidence for prevention and intervention of obsessive-compulsive symptoms in medical students. @* Methods@#Medical students were enrolled from a medical college in Hangzhou and were selected among 3 to 6 classes from Grade One to Grade Four using stratified cluster sampling method. The students were assessed with Obsessive Beliefs Scale-44 （OBD-44） and Obsessive Compulsive Scale Revised （OCD-R）. Linear regression model was conducted to analyze the association between obsessive beliefs and obsessive-compulsive symptoms in medical students. @*Results@# As 592 medical students were surveyed and 544 responses were valid, the response rate was 91.89%. The median score of OCD-R of medical students was 15,and 28.86 of them had obsessive-compulsive symptoms. Concerning OBD-44, the total score of medical students was 154.11±36.05, the scores of responsibility/threat, perfectionism/certainty and importance/control of thoughts were 61.12±14.53, 58.68±14.31 and 32.90±10.76, respectively. The Linear regression analysis demonstrated that gender could predict checking,washing,obsessing and neutralizing; responsibility/threat estimate predicted hoarding and obsessing ;perfectionism/certainty was the most significant predictor of checking,ordering,washing, neutralizing;and importance/control of thoughts predicted hoarding,checking,ordering,washing and obsessing（all P<0.05）.@*Conclusion@#Gender, importance/control of thoughts and perfectionism/certainty have significant impact over most of obsessive-compulsive symptoms in medical students.

Multiple mediating effects of intolerance of uncertainty,obsessive-compulsive and generalized anxiety on neuroticism and insomnia in college students / 中华行为医学与脑科学杂志

Objective To explore composited multiple mediating effects of intolerance of uncertain-ty,generalized anxiety symptoms and obsessive-compulsive symptoms between neuroticism and insomnia. Methods In this study,405 university students were evaluated using several questionnaires,including Ath-ens Insomnia Scale,Intolerance of Uncertainty Scale,the Penn State Worry Questionnaire and Obsessive-com-pulsive. Inventory-Revised and Eysenck Personality Questionnaire-Revised Short Scale for Chinese. Results The scores of Athens Insomnia Scale(4. 07±2. 57),Intolerance of Uncertainty Scale(72. 33±14. 42),The Penn State Worry Questionnaire(40. 57±10. 35),Compulsive Activity Checklist-Revised(1. 60±1. 45) and Eysenck Personality Questionnaire-Revised Short Scal(4. 86±3. 22) were positively correlated with each other(r=0. 18~0. 64,P<0. 01). Model fit indices in SEM were χ2/df=2. 15,P>0. 05;CFI=0. 99;GFI=0. 99;NFI=0. 99;NNFI(TLI)=0. 97;RMSEA=0. 05. The results indicated that neuroticism directly af-fected insomnia ( effect size 0. 125), neuroticism affects insomnia through generalized anxiety symptoms (effect size 0. 082) and obsessive-compulsive symptoms( effect size 0. 053) respectively. Thus,generalized anxiety symptoms and obsessive-compulsive symptoms were parallel mediators. Neuroticism affects general-ized anxiety symptoms through intolerance of uncertainty, and then affected the insomnia ( effect size 0. 022). And neuroticism affected obsessive-compulsive symptoms through intolerance of uncertainty, and then affected the insomnia ( effect size 0. 014). Conclusion The neuroticism personality of university students can influence insomnia through the multiple mediation model of intolerance of uncertainty,general-ized anxiety symptoms and obsessive-compulsive symptoms.

Study on obsessive-compulsive symptoms and influencing factors in college students with left-behind experience / 中华疾病控制杂志

Objective To understand the obsessive-compulsive symptoms (OCS) and relative influencing factors among college students with left-behind experience. Methods College students with left-behind experience were selected from three universities in Anhui Province. The Chinese Obsessive-Compulsive Inventory-Revised (OCI-R), Rosenberg Self-Esteem Scale (RSES), Self-Rating Depression Scale (SDS) and self-edited basic situation questionnaires were used to measure the OCS, self-esteem, depression and left-behind experience. Multivariate logistic regressions model was applied to examine the influential factors of OCS. Results A total of 2 291 college students with left-behind experience were investigated. The detection rate for OCS in college students with left-behind experience were 26.5%. Regarding the OCS in college students with left-behind experience, significant differences were found in the following aspects: frequency of meeting with parents, parenting style, conflicts with caregivers, smoking and drinking (all P<0.05). Logistic regression analysis showed that caregiver adopts strict parenting style (OR=1.300, 95%CI:1.025-1.649,P=0.030), indulgent parenting style (OR=1.372, 95%CI:1.017-1.852, P=0.038), smoking (OR=1.982, 95%CI:1.305-3.011, P=0.001), depressive symptoms (OR=2.423, 95%CI:1.954-3.005, P<0.001), medium self-esteem (OR=0.604, 95%CI:0.481-0.759, P<0.001) and high self-esteem (OR=0.488, 95%CI:0.362-0.659, P<0.001) were influencing factors of OCS. Conclusions The prevalence rate of OCS among college students with left-behind experience is high. Some interventions should be taken to reduce the OCS among college students with left-behind experience.

Obsessive-compulsive symptoms in children with first degree relatives diagnosed with obsessive-compulsive disorder

Objective: A first-degree relative affected by obsessive-compulsive disorder (OCD) and obsessive-compulsive symptoms (OCS) in childhood is an important risk factor for developing the disorder in adulthood. The relationship between a family history of OCD and the presence of OCS and its correlates in childhood is not well established. Methods: A total of 66 children whose parents or siblings have been diagnosed with OCD were assessed for the presence of OCS and clinical correlates. Results: Three children (4.5%) were reported to have received an OCD diagnosis and another 26 (39.4%) were identified as having OCS. Children with OCS had higher rates of coercive behavior and came from families with lower socioeconomic status. Contamination/cleaning dimension symptoms in the proband were associated with OCS in the assessed children. Conclusion: OCS are frequent among family members of individuals with OCD and are associated with socioeconomic status, coercive behaviors and proband contamination/cleaning symptoms. Future longitudinal studies should test the risk of developing OCD in association with these characteristics.

The effect of obsessive compulsive symptoms on psychopathology in patients with schizophrenia

Abstract Background: There is a growing interest on the impact of comorbid obsessive-compulsive symptoms (OCS) on the course and severity of schizophrenia in recent years. Objective: This study determined the prevalence of OCS in schizophrenia patients and the clinical outcomes of the comorbidity. Methods: A total of 220 schizophrenia patients were recruited. All the participants completed Structure Clinical Interview version, Yale Brown Obsessive Compulsive Scale, Calgary Depression Scale for Schizophrenia, Columbia Suicide Severity Rating Scale and World Health Organization Quality of Life - Brief Version (WHOQOL-BREF). Results: Significantly higher number of schizophrenia patients with OCS were taking Clozapine (p = 0.023) and antidepressants (p = 0.013). Schizophrenia patients with OCS showed more severe positive (p < 0.001) and general symptoms (p < 0.001) of schizophrenia, higher depressive symptoms (p = 0.013), higher suicidality (p < 0.001), more hospitalization (p = 0.044), poorer physical (p = 0.034) and psychological (p = 0.032) domain in WHOQOL-BREF. Discussion: Schizophrenia patients with OCS are associated with more severe psychopathology and depressive symptoms which subsequently suffered poorer physical and psychological health. Hence, recognition of OCS in schizophrenia and early initiation of effective treatment may be able to reduce the burden for people with chronic mental illness.

Obsessive-Compulsive Symptoms in Relation to Duration of Schizophrenia

OBJECTIVES: The aim of this study was to evaluate the psychopathological features such as depression and anxiety in schizophrenics with obsessive-compulsive symptoms (OCS) as well as the severity of OCS according to duration of schizophrenia. METHODS: We randomly selected sixty four inpatients with schizophrenia. We classified the patients into two groups (OCS group, non-OCS group) according to the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS). Clinical and demographic features were evaluated. To assess OCS, Y-BOCS were performed. The Korean version of the Positive and Negative Syndrome Scale(K-PANSS), the Brief Psychiatric Rating Scale (BPRS), the Korean version of the Calgary Depression Scale for Schizophrenia (K-CDSS), the Beck Anxiety Inventory (BAI) and the Satisfaction With Life Scale (SWLS) were conducted. Independent t-test and chi-square test were conducted to compare the two groups. Pearson correlation analysis was performed to examine the relationship between the duration of schizophrenia and the Y-BOCS score. RESULTS: The Y-BOCS, K-CDSS, and BAI scores were higher in the OCS group. There was a significant correlation between the duration of schizophrenia and the Y-BOCS score. CONCLUSIONS: Anxiety and depression symptoms were severe in the OCS group. In addition, the results of this study indicate that the longer duration of schizophrenia, the more severe the OCS. Therefore, the evaluation of OCS in schizophrenics should be accompanied by treatment intervention.

Dissociative experiences in bipolar disorder II: Are they related to childhood trauma and obsessive-compulsive symptoms?

The aim of this study is to investigate the presence of dissociative symptoms and whether they are related to childhood trauma and obsessive-compulsive symptoms in bipolar disorder type II (BD-II). Methods Thirty-three euthymic patients (HDRS<8, YMRS<5) and 50 healthy subjects were evaluated by SCID-I and SCID-NP. We excluded all first and second-axis comorbidities. All patients and healthy subjects were examined with the Dissociative Experiences Scale (DES), Childhood Trauma Questionnaire (CTQ-53), and Yale-Brown Obsessive-Compulsive Disorder scale (Y-BOCS). Results In pairwise comparisons between the BD-II and control groups, the total CTQ, emotional abuse, emotional neglect, DES, and total Y-BOCS scores in the BD-II group were significantly higher than those in the control group (p < 0.05). There were five cases with DES scores over 30 (15.2%) and one case (2%) in the control group. DES was weakly correlated with total CTQ and Y-BOCS in patients diagnosed with BD-II (r = 0.278, p < 0.05 and r = 0.217, p < 0.05, respectively). While there was no correlation between total CTQ and Y-BOCS, the CTQ sexual abuse subscale was found to be related to Y-BOCS (r = 0.330, p < 0.05). Discussion These results suggest that there is a relation between childhood traumas and obsessive-compulsive symptoms, or that dissociative symptoms are more associated with anxiety than obsessive symptoms, which prevents the increase of obsessive-compulsive symptoms in BD-II...

Obsessive-compulsive symptoms and obsessive-compulsive disorder in adolescents: a population-based study

Objectives: To estimate the prevalence of obsessive-compulsive symptoms (OCS) and disorder (OCD) among adolescents and to describe OCD characteristics according to gender. Methods: Participants were selected by cluster sampling at seven high-schools in southern Brazil. In the first stage, 2,323 students were screened for OCS; in the second stage, adolescents scoring ≥ 21 on the OCI-R scale were individually interviewed. OCD diagnosis was established using a semi-structured interview (Schedule for Affective Disorders and Schizophrenia for School Aged Children: Present and Lifetime Version - K-SADS-PL). Results: The past-month estimated prevalence of OCS was 18.3%, and the point estimated prevalence of OCD, 3.3%. Girls showed higher scores (OCS: 24.8 vs. 14.4%; OCD: 4.9 vs. 1.4%; p < 0.001). Only 9.3% of OCD adolescents had been diagnosed and 6.7% received treatment. The most frequent/severe DY-BOCS dimensions were miscellaneous (86.7%; mean score 6.3±3.8) and symmetry (85.3%; 5.9±3.8). Female OCD adolescents predominantly showed depression (p = 0.032), and male adolescents, tic disorders (p = 0.006). Conclusions: OCD is underdiagnosed in adolescents, and few are treated. Future studies should investigate the relationship between OCS and the onset of OCD. .

Voxel-Based Morphometry Study of Gray Matter Abnormalities in Neurodegenerative Disease with Obsessive-Compulsive Behaviors / 정신신체의학

OBJECTIVES: Obsessive-compulsive(OC) symptoms have yet to be directly studied in neurodegenerative conditions involving behavioral changes. To examine regional abnormalities in the brains of dementia patients with OC symptoms, we assessed the gray matter density using voxel-based morphometry(VBM). METHODS: We performed brain magnetic resonance imaging(MRI) with VBM analysis in 106 dementia patients with OC behaviors. In this study, OC behaviors were investigated in patients with neurodegenerative disease using the modified Manchester Behavior Questionnaire. RESULTS: The OC behavior scores were correlated with structural brain volume using VBM. The total OC symptom score correlated negatively with the volume of both putamens, the right middle orbitofrontal gyrus, both anterior cingulate cortices, and the left insula(p<0.001, uncorrected). No gray matter reductions were associated specifically with the OC symptom sub-categories. CONCLUSIONS: Our results suggest that abnormalities in these brain regions may play an important role in the pathophysiology of OCD in neurodegenerative disease. This is the first lesion study to investigate the neural basis of OCD behaviors in neurodegenerative disease.

Systemizing effect study on obsessive-compulsive symptoms and autism-spectrum quotient among college students / 中华行为医学与脑科学杂志

Objective To investigate the correlations between obsessive-compulsive symptoms and autism-spectrum quotient and explore if systemizing is the mediator between them. Methods With Padua Inventory (PZ) ,AQ and Systemizing Quotient (SQ), 1901 college students were assessed with stratified random sampling survey. Results Compared with the femal students, score of systemizing in male students had a significant increase ( (26. 773 ± 9.225 )vs (22.017 ± 7 ± 934), P ＜0.01 ). AQ total score was significantly positive correlated with PI total score( r=0. 336, P＜0.01 ),and correlation was also found among SQ,AQ and PI in different degrees. the mediating effect of systemizing was significant. The regression equation was AQ = 18. 942 +0. 064PI -0. 022SQ (P ＜ 0.01 ). Conclusion There are positive correlation between obsessive-compulsive symptoms and AQ in college students, and systemizing is the mediator between above symptoms.

Tics: los trastornos del movimiento más frecuentes en los niños / Tics: the most frequent movement disorders in children

Los tics son los trastornos del movimiento más frecuentes en los niños y su mayor prevalencia es en la edad escolar. La mayoría son transitorios, pero algunos pueden tener repercusiones negativas en los ámbitos escolar, familiar y social, que pueden llevar a fracaso escolar, baja autoestima y disfunción social. Algunos de los tics se relacionan con el trastorno de déficit de atención e hiperactividad (TDAH) y con otras enfermedades que requieren diagnóstico oportuno y adecuado tratamiento. En esta revisión sobre los tics se incluyen los siguientes aspectos: epidemiología, etiología, factores de riesgo, caracterización, enfermedades asociadas, diagnóstico, tratamiento y pronóstico.

Tics are the most frequent movement disorders during childhood; their highest prevalence occurs during school age. Most tics are transient but some of them may have serious repercussions from the educational, familial, and social points of view, leading to school failure, low self-esteem, and social dysfunction. Some tics are related to the attention-deficit hyperactivity disorder, and to other diseases that should be opportunely and adequately treated. In this review on tics the following aspects are included: epidemiology, etiology, risk factors, characterization, associated diseases, diagnosis, treatment, and prognosis.

Relationship between obsessive-compulsive and psychotic symptoms in schizophrenia patients / 中华行为医学与脑科学杂志

Objective To investigate the relatiouship between obsessive-compulsive symptoms and schizophreuia symptoms in schizo-obsessive patients, and to address the feature of insight. Methods Fifty-two cases of schizophrenia with obsessive-compulsive symptoms were assessed by Yale-Brown obsessive-compulsive scale( YBOCS) and positive and negative syndrome scale(PANSS). Results The Y-BOCS overall severity score(26.7 ±4.78)was not correlated with the PANSS total score(86.9 ± 13.4)( r=0. 191 , P＞0.05), there was significant association between the insight score( 2.65 ±0.81 )and the PANSS total score( 86. 9 ± 13.4 ) ( r = 0. 416, P＜0. 01 ),and the same between the insight score( 2.65 ± 0. 81 )and the Y-BOCS overall severity score(26.7 ±4.78 ) ( r = 0. 387, P ＜ 0. 01 ). Conclusion Obsessive-compulsive symptoms and schizophrenia symptoms in schizo-obsessive patients are not correlated, obsessive-compulsive symptoms are not inherent symptoms of schizophrenia. As insight is correlated with both obsessive-compulsive symptoms and schizophrenia symptoms, anti-psychotic along with anti-compulsive treatment should be able to effectively improve the insight of schizo-obsessive patients.

Esquizofrenia con síntomas obsesivos compulsivos o el grupo de las Esquizofrenias Esquizoobsesivas: características clínicas y pronósticas / Schizophrenia with obsessive-compulsive symptoms or the group of schizo-obsessive schizophrenias: clinical characteristics and prognosis

Este trabajo es una revisión bibliográfica crítica de lo publicado a la fecha acerca de la Esquizofrenia Esquizoobsesiva o el grupo de las Esquizofrenias Esquizoobsesivas, en el cual se repasan las características clínicas, neuropsicológicas y pronósticas. Se discute además la replicabilidad de los hallazgos publicados y se propone un esquema nosológico de integración.

Obsessive-compulsive symptoms (OCS) have been observed in a substantial proportion of schizophrenic patients. In this paper, the rate of occurrence of OCS and OCD in schizophrenic patients, and also the interrelationship between OCS and schizophrenic symptoms, depressive symptoms, cognitive function and age are reviewed. The author proposes to use the term "group of schizo-obsessive disorders" and proposes an integrate classification system.

Treatment of Clozapine-induced Obsessive-compulsive Symptoms in Schizophrenia

BACKGROUND: Clozapine is a unique atypical antipsychotic medication. It is considered to be superior, even amongst the newer agents, in treatment-resistant schizophrenia. However, de novo emergence or exacerbation of obsessive-compulsive(OC) symptoms during treatment with clozapine has been reported. We prospectively evaluated 19 cases which newly developed OC symptoms during clozapine treatment and discussed the treatment of OC symptoms induced by it. METHODS: We recruited 19 patients(8 males, 11 females) with a DSM-IV diagnosis of schizophrenia and schizoaffective disorder who had developed OC symptoms during clozapine treatment. OC symptoms were assessed using the Padua-ICMA and YBOCS on a monthly basis over three months. RESULTS: Eleven female and eight male patients were enrolled and the average age of patients was 32.8 years. At baseline, no patients showed OC symptoms. Moderate to severe OC symptoms appeared with mean daily dose of 298.68 mg of clozapine. There were no significant differences in improving OC symptoms between the clozapine dose reduction group and the OC treatment group. CONCLUSION: We noticed the possibility that the appearance of OC symptoms is connected with the effect of clozapine. The clozapine-induced OC symptoms were improved both by reducing clozapine daily doses, and by adding OC treatment drugs. With other atypical antipsychotics now available, to know and treat the side effects of clozapine would be of considerable value, offering clinical guidance in making a decision on treatment-resistant schizophrenia.

Treatment of Obsessive Symptoms in Schizophrenic Patient with a Risperidone-Fluoxetine Combination / 대한정신약물학회지

Recent studies have reported that obsessive-compulsive (OC) symptoms are highly prevalent in schizophrenia, and schizophrenic patients with OC symptoms have a poorer clinical course compared to those without OC symptoms. In spite of many previous case reports, treatment of OC symptoms in schizophrenia has not been systematically studied. We report a patient with chronic schizophrenia who had obsessive symptoms such as bizarre, stereotyped behaviors. Treatment with olanzapine and risperidone, resulted in partial response for his psychotic symptoms, respectively. The obsessive symptoms, however, persisted and fluoxetine was added to the risperidone regimen. After 4 weeks of combination treatment, fluoxetine was titrated up to 80 mg/day and his obsessive symptoms became less in frequency and intensity. After 7 weeks on combination treatment of risperidone and fluoxetine, obsessive symptoms resulted in a significant reduction. On the 20 months of following, he remained in a recovered state and had been treated with risperidone 4 mg/day, and fluoxetine 20 mg/day.
