In the present study, individuals with obsessive-compulsive disorder (OCD) who also had excessive health concerns (n = 56) were compared with OCD individuals without such concerns (n = 343) regarding their OCD symptom severity, types of obsessions and compulsions, insight into the irrationality of their obsessions, and prevalence of generalized anxiety disorder. While the presence of health concerns did not affect the severity of OCD symptoms, the groups differed with respect to the types of symptoms displayed: those with health concerns had more somatic and harm obsessions, and checking compulsions: whereas those without such concerns had more contamination obsessions and washing compulsions. The insight of both groups ranged from poor to excellent, yet the number of individuals with poor insight was greater among those with health concerns than those without. Generalized anxiety disorder was also more prevalent among OCD individuals with excessive health concerns. 相似文献

BACKGROUND: Among patients with tic disorders, a distinctive clinical profile of obsessive-compulsive symptomatology has been described. The present investigation was designed to document the phenomenology of obsessive-compulsive symptoms (OCS) among patients with Sydenham chorea (SC), the neurologic variant of rheumatic fever. We hypothesized that OCS occurring in association with SC would be similar to those among patients with tic disorders. METHODS: The authors studied the presence of OCS in 73 patients with SC by using the Yale-Brown Obsessive-Compulsive Scale at the Pediatric Clinics of the University of Sao Paulo Medical Center in Sao Paulo, Brazil (n = 45) and at the National Institute of Mental Health in Bethesda, Maryland (n = 28). RESULTS: The most frequent symptoms observed among subjects with comorbid SC and OCS were aggressive, contamination, and somatic obsessions and checking, cleaning, and repeating compulsions. A principal component factor analysis yielded a five-factor solution (accounting for 64.5% of the total variance), with contamination and symmetry obsessions and cleaning compulsions loading highly. CONCLUSIONS: The symptoms observed among the SC patients were different from those reported by patients with tic disorders but were similar to those previously noted among samples of pediatric patients with primary obsessive-compulsive disorder. 相似文献

Tourette syndrome (TS) is a neurodevelopmental disorder characterised by multiple motor and phonic tics, which are associated with sensory symptoms (premonitory urges). Little is known about the nature of the subjective urges and repetitive behaviours which are intrinsic to TS. This study assessed the relationship between specific urges and repetitive behaviours in 108 consecutive adult patients recruited at a specialist TS Clinic. Analysis of self-report measures of sensory symptoms (Premonitory Urge for Tics Scale) and repetitive behaviours (Motor tic, Obsessions and compulsions, Vocal tic Evaluation Survey) showed that different types of urges are associated with simple/complex tics and obsessive–compulsive symptoms. 相似文献

OBJECTIVE: We studied the comorbid behavioural and mood problems in children with non-psychiatric Tourette's syndrome (TS) and their relationship with severity of tic disorder. METHOD: Sixty-nine TS children and 69 healthy controls were assessed by Child Behavior Checklist (CBCL) and Yale Global Tic Severity Scale (YGTSS). The relationships between behavioural problems and severity of tic symptoms were analysed statistically by comparison, correlation and multiple linear regression. RESULTS: Tourette's syndrome patients scored significantly lower (p<0.01) on the CBCL competency subscales and total score, and higher on all behavioural problem subscales and total score (p<0.01). Expectedly, the TS children had lower social competence than normal children. Among the TS children, the severity of tic symptoms is positively correlated with the severity of overall impairment in school and social competence. When the behavioural and mood problems commonly associated with TS were studied in detail, we found that delinquent behaviour, thought problems, attention problems, aggressive behaviour and externalizing are positively correlated with severity of tic symptoms. CONCLUSION: The findings indicated that children with TS-only also had a broad range of behavioural problems, and some of these were related to the severity of tic symptoms. 相似文献

BACKGROUND: Case studies and a placebo-controlled study previously suggested the effectiveness of immunomodulatory therapy in patients with tic or related disorders whose symptoms show a relationship with streptococcal infections. No data are available on the effectiveness of intravenous immunoglobulins (IVIG) on tic severity in unselected tic disorder patients. METHOD: Thirty patients with a DSM-IV tic disorder were randomly assigned to IVIG (1 g/kg on 2 consecutive days; mean age = 28.71 years; range, 14-53 years) or placebo (mean age = 30.73 years; range, 14-63 years). Symptoms were rated with the Yale Global Tic Severity Scale, the Yale-Brown Obsessive Compulsive Scale, and the Clinical Global Impressions scale of symptom change with regard to tic severity. These were used at baseline and on weeks 2, 4, 6, 10, and 14 posttreatment, after which blinding was broken. The study was conducted from March through August 2002. RESULTS: We observed no significant differences between both treatment groups regarding posttreatment changes in tic severity. Severity of obsessions and compulsions, which was in the subclinical range, decreased significantly in the IVIG group compared with the placebo group at week 6 (p =.02). Then, there was a 32.3% improvement in the IVIG group compared with baseline. Though this improvement was maintained over the following 8 weeks, no statistically significant differences between the IVIG and the placebo group with regard to improvements in obsessions and compulsions were detected at subsequent assessments. IVIG treatment was associated with significantly more side effects than placebo, most notably headache. CONCLUSION: Based on the present results, IVIG cannot be recommended in tic disorders. 相似文献

Tic disorders have a strong male predominance, with a male-to-female ratio of 4:1 in Tourette syndrome (TS) and 2:1 in persistent tic disorders. In other neurodevelopmental conditions, such as autism spectrum disorder (ASD) and attention-deficit/hyperactivity disorder (ADHD), the disparity in sex distribution has been partially related to differences in symptom presentation between males and females. In tic disorders, however, little research has been conducted on this topic, probably due to the limited access to large samples with a significant proportion of females. The aim of this study was to describe sex differences in the clinical presentation of tic disorders in children and adolescents in one of the largest pediatric samples with TS/persistent tic disorders (n = 709, 23.3% females) recruited as part of the European Multicenter Tics in Children Study (EMTICS). Validated measures assessed the severity of tics and comorbid psychiatric symptoms. Using mixed-effect models, we found that sex had a significant influence on the severity of tics, ADHD symptoms, ASD symptoms, and emotional problems. Males had more severe symptoms than females, except for emotional problems. We also observed a statistically significant interaction between sex and age on the severity of tics and compulsions, with females showing higher symptom severity with increasing age than males. These findings indicate that the clinical presentation of TS/persistent tic disorders varies with sex. Males seem to exhibit a more noticeable pattern of clinical symptoms at a younger age that may contribute to their earlier detection in comparison to females. 相似文献

Savron G, Fava GA, Grandi S, Rafanelli C, Raffi AR, Belluardo P. Hypochondriacal fears and beliefs in obsessive-compulsive disorder. Acta Psychiatr Scand 1996: 93: 345–348. © Munksgaard 1996. The relationship of obsessions and compulsions with hypochondriasis is receiving increasing attention, but has not been substantiated by adequate research. The Illness Attitude Scales (IAS), which identify hypochondriacal patients, were administered to 30 patients with DSM-IV obsessive-compulsive disorder and 30 healthy control subjects matched for sociodemographic variables. All IAS scales were significantly higher in patients with obsessions and compulsions. However, there were no significant differences between patients and controls in the number of subjects whose symptom intensity exceeded a clinical threshold for hypochondriasis and disease phobia. Furthermore, hypochondriacal fears and beliefs were poorly correlated with obsessions and compulsions. The results suggest the presence of mild abnormal illness behaviour in patients with obsessive-compulsive disorder. unlike the situation in patients with panic disorder and depression. 相似文献

The tic disorder Tourette's Syndrome (TS) and obsessive-compulsive disorder (OCD) are comorbid behavioral disorders, suggesting a shared but still unknown neuronal basis. To 'circuit-test' such behaviors, we previously engineered transgenic mice expressing a neuropotentiating protein (cholera toxin A1 subunit) within a cortical-limbic subset of dopamine D1-receptor expressing (D1+) neurons known to trigger glutamatergic excitation of orbitofrontal, sensorimotor, limbic and efferent striatal circuits thought to be hyperactive or affected in OCD and TS. These mice exhibited OCD-like behaviors including generalized behavioral perseveration and compulsion-like leaping and grooming-associated pulling and biting of skin and hair. We now report that these OCD-like mice, like humans, also exhibit comorbid TS-like behaviors, including juvenile-onset tics; increased tic number, complexity and flurries; increased tic severity in males; voluntary tic suppression; and tic responsiveness to a non-cataleptic TS+OCD drug therapy (clonidine, 0.01 mg kg(-1)). These data suggest that hormonal gender differences, apart from the influence of genetic or autoimmune etiologic factors, may be sufficient to aggravate tic severity in human TS males compared to TS females. These data also proffer a precise neuronal basis for TS+OCD, wherein tics and primary compulsions or obsessions are evoked by hyperactivity of various cortical-limbic projection neurons' glutamatergic output to efferent targets like the striatum. The 'Cortical-limbic Glutamatergic Neuron' (CGN) neuronal circuit model merges formerly opposed neurotransmitter models of TS and OCD, and is consistent with new clinical reports of increased cortical hyperactivity, striatal glutamate and striatal inhibitory D2 receptors, and reduced striatal responsiveness, in these disorders. 相似文献

OBJECTIVE: An anxiety disorder severely affects the sufferer's quality of life (QOL), and this may be particularly true of those with obsessive-compulsive disorder (OCD). This study examines the differential impact of obsessions, compulsions, and depression comorbidity on the QOL of individuals with OCD. METHOD: Forty-three individuals diagnosed with OCD according to DSM-IV criteria and experiencing clinically significant obsessions and compulsions completed measures of QOL, obsessive-compulsive symptom severity, and depression severity. RESULTS: Obsession severity was found to significantly predict patient QOL, whereas the severity of compulsive rituals did not impact on QOL ratings. Comorbid depression severity was the single greatest predictor of poor QOL, accounting for 54% of the variance. CONCLUSIONS: Given the importance of these symptoms, treatments that directly target obsessions and secondary depression symptoms in OCD are warranted. However, replication of these findings in a prospective cohort study is required, because although the the current study's cross-sectional design allows for the examination of the associations among obsessions, depression, and QOL, it cannot establish their temporal framework (that is, causal relations). 相似文献

Tourette syndrome (TS) patients often complain of sleep problems, and questionnaire studies indicate that sleep disturbance is frequent. Decreased slow wave sleep and increased awakenings have been reported in laboratory polysomnography in TS patients, and a serotoninergic disorder of arousal has been postulated. We recorded outpatient sleep in 20 patients newly diagnosed with TS utilizing a 4-channel cassette EEG system. The newly-diagnosed patients were predominantly male, and ranged in age from 10 to 36 years. Some had taken psychotropic medications in the past, but none had been treated systematically for TS. Seven patients had chronic tics only, 8 had tics and attention deficit-hyperactivity, and 5 had tics plus obsessions and compulsions. None had other medical, neurologic, or psychiatric disorders. All were nocturnal sleepers, and were recorded in their usual sleeping environments and routines. TS patients had reduced sleep, decreased sleep efficiency, increased awakenings, and decreased slow wave sleep. Tic patients had increased nocturnal awakenings and movements, particularly those who had tics during sleep. Sleep fragmentation and loss of slow wave sleep was most marked in TS patients with attention deficit-hyperactivity. Sleep latency was increased, REM sleep reduced, and REM sleep latency decreased in TS patients with obsessions and compulsions. These findings accord with previous reports of sleep disturbance in TS, and suggest that these disturbances may vary with TS symptoms. Chronic tics may persist in sleep and cause awakenings, TS with attention deficit may be associated with a disorder of arousal and alertness, and obsessions and compulsions may be manifestations of a biochemical disturbance involving paradoxical sleep. 相似文献

Several studies suggest increased prevalence-rates of obsessive-compulsive symptoms (OCS) and even of obsessive-compulsive disorder (OCD) in patients with schizophrenic disorders. Moreover, it has been recently proposed the existence of a distinct diagnostic sub-group of schizo-obsessive disorder. However, the further investigation of the OCS or OCD-schizophrenia diagnostic comorbidity presupposes the accurate clinical differential diagnosis of obsessions and compulsions from delusions and repetitive delusional behaviours, respectively. In turn, this could be facilitated by a careful comparative examination of the phenomenological features of typical obsessions/compulsions and delusions/repetitive delusional behaviours, respectively. This was precisely the primary aim of the present investigation. Our examination included seven features of obsessions/delusions (source of origin and sense of ownership of the thought, conviction, consistency with one’s belief-system, awareness of its inaccuracy, awareness of its symptomatic nature, resistance, and emotional impact) and five features of repetitive behaviours (aim of repetitive behaviours, awareness of their inappropriateness, awareness of their symptomatic nature, and their immediate effect on underlying thought, and their emotional impact). Several of these clinical features, if properly and empathically investigated, can help discriminate obsessions and compulsive rituals from delusions and delusional repetitive behaviours, respectively, in patients with schizophrenic disorders. We comment on the results of our examination as well as on those of another recent similar investigation. Moreover, we also address several still controversial issues, such as the nature of insight, the diagnostic status of poor insight in OCD, the conceptualization and differential diagnosis of compulsions from other categories of repetitive behaviours, as well as the diagnostic weight assigned to compulsions in contemporary psychiatric diagnostic systems. We stress the importance of the feature of mental reflexivity for understanding the nature of insight and the ambiguous diagnostic status of poor insight in OCD which may be either a marker of the chronicity of obsessions, or a marker of their delusionality. Furthermore, we criticize two major shortcomings of contemporary psychiatric diagnostic systems (DSM-IV, DSM-V, ICD-10) in their criteria or guidelines for the diagnosis of OCD or OCS: first, the diagnostic parity between obsessions and compulsions and, second, the inadequate conceptualization of compulsions. We argue that these shortcomings might artificially inflate the clinical prevalence of OC symptoms in the course of schizophrenic disorders. Still, contrary to a recent proposal, we do not exclude on purely a priori grounds the possibility of a concurrence of genuine obsessions along with delusions in patients with schizophrenia. 相似文献

The Yale-Brown Obsessive Compulsive Scale was designed to remedy the problems of existing rating scales by providing a specific measure of the severity of symptoms of obsessive-compulsive disorder that is not influenced by the type of obsessions or compulsions present. The scale is a clinician-rated, 10-item scale, each item rated from 0 (no symptoms) to 4 (extreme symptoms) (total range, 0 to 40), with separate subtotals for severity of obsessions and compulsions. In a study involving four raters and 40 patients with obsessive-compulsive disorder at various stages of treatment, interrater reliability for the total Yale-Brown Scale score and each of the 10 individual items was excellent, with a high degree of internal consistency among all item scores demonstrated with Cronbach's alpha coefficient. Based on pretreatment assessment of 42 patients with obsessive-compulsive disorder, each item was frequently endorsed and measured across a range of severity. These findings suggest that the Yale-Brown Scale is a reliable instrument for measuring the severity of illness in patients with obsessive-compulsive disorder with a range of severity and types of obsessive-compulsive symptoms. 相似文献

The goal of this study was to discriminate subtypes of pediatric obsessive-compulsive disorder (OCD) among youth with and without a comorbid tic disorder. Seventy-four youth (M(age)=9.7+/-2.3 years) with a principal diagnosis of OCD, with (n=46) or without (n=28) a comorbid tic disorder, were assessed with a semi-structured diagnostic interview and the Children's Yale Brown Obsessive-Compulsive Scale (CY-BOCS). The CY-BOCS Symptom Checklist was used to categorize obsessions and compulsions. Group differences were analyzed by t tests, chi(2), and discriminant function analyses. Results suggested that subjects without tics had significantly more contamination obsessions, sexual obsessions, and counting compulsions than youth with comorbid tics. Generally speaking, however, youth with and without tics had similar symptom presentations. These data suggest that pediatric OCD patients with and without comorbid tics may have some aspects of symptom presentation that differ, but generally have more OCD symptoms in common than different. Implications of these findings on clinical presentation and treatment efficacy are highlighted. 相似文献

BackgroundThe identification of distinct subtypes based on comorbidity offers potential utility in understanding variations in the clinical expression of obsessive-compulsive disorder (OCD). Hence, we examined the hypothesis whether patients with OCD with major depressive disorder (MDD) or anxiety disorder comorbidity would differ from those without in terms of phenomenology. MethodsA total of 545 consecutive patients who consulted a specialty OCD clinic during the period 2004 to 2009 at a psychiatric hospital in India formed the sample. They were evaluated with the Yale-Brown Obsessive-Compulsive Scale (YBOCS), the Mini International Neuropsychiatric Interview, and the Clinical Global Impression scale. ResultsAmong 545 patients, 165 (30%) had current MDD, and 114 (21%) had current anxiety disorder comorbidity. Patients with OCD with MDD were mostly women who had a greater severity of OCD symptoms, more of obsessions (especially religious), greater occurrence of miscellaneous compulsions (need to confess or need to touch), higher suicidal risk, and past suicidal attempts. Patients with OCD with anxiety disorder had an earlier onset of illness that was associated with prior life events, less of compulsions, more of aggressive and hoarding obsessions, pathologic doubts, checking, and cognitive compulsions. ConclusionsObsessive-compulsive disorder, when comorbid with MDD, is more severe and is associated with higher suicidal risk. On the other hand, anxiety disorder comorbidity seems to influence not so much the morbidity but the phenotypic expression of OCD. 相似文献

BACKGROUND: Tourette Syndrome (TS) has a complex etiology and wide variability in phenotypic expression. Identifying underlying symptom patterns may be useful for etiological and outcome studies of TS. METHODS: Lifetime tic and related symptom data were collected between 1996 and 2001 in 121 TS subjects from the Central Valley of Costa Rica and 133 TS subjects from the Ashkenazi Jewish (AS) population in the US. Subjects were grouped by tic symptoms using an agglomerative hierarchical cluster analysis. Cluster membership was tested for association with available ancillary information (age of onset, tic severity, comorbid disorders, medication treatment and family history). RESULTS: Cluster analysis identified two distinct groups in each sample, those with predominantly simple tics (cluster 1), and those with multiple complex tics (cluster 2). Membership in cluster 2 was correlated with increased tic severity, global impairment, medication treatment, and presence of comorbid obsessive-compulsive symptoms in both samples, and with family history of tics, lower verbal IQ, earlier age of onset, and comorbid obsessive-compulsive disorder and attention-deficit/hyperactivity disorder in the AS sample. CONCLUSIONS: This study provides evidence for consistent and reproducible symptom profiles in two independent TS study samples. These findings have implications for etiological studies of TS. 相似文献

BACKGROUND: Patients with obsessive-compulsive disorder (OCD) are troubled by repeated obsessions and/or compulsions, which seem senseless and frequently repugnant. OBJECTIVE: The study examines the differential impact of obsessions and compulsions on the quality of life (QoL) of patients with OCD. METHODS: Seventy-five patients (43 females, 32 males) between 21 and 62 years old with OCD (ICD 10 F42.0-F42.2) were recruited from the outpatient clinic for anxiety disorders at the Department of Psychiatry of the University of Leipzig. The severity of OCD symptoms was assessed by the Yale Brown Obsessive-Compulsive Scale (a standardized, clinician-administered scale), and depressiveness was assessed with the Beck Depression Inventory (a self-report instrument). QoL was assessed by means of the WHOQOL-BREF, a self-administered questionnaire developed by WHO. RESULTS: Compulsions reduced patients' QoL in the WHOQOL-BREF domains 'physical well-being', 'psychological well-being' and 'environment', whereas obsessions did not have any impact on QoL ratings. Depressive symptoms were a strong predictor of poor QoL in OCD patients. CONCLUSIONS: In order to judge the QoL of OCD patients, obsessions and compulsions have to be considered differently. Diagnosing and treating depressive symptoms is important for improving the QoL in OCD. 相似文献

This study aimed to investigate the clinical features of obsessive-compulsive disorder (OCD) and the possible association between obsessive-compulsive symptoms and culture-related characteristics in a sample of Turkish patients with OCD. We studied 141 patients with OCD (according to DSM-IV criteria) consecutively admitted to our outpatient clinic during the period from February 1998 to December 2003. We used the Turkish version of the Structured Clinical Interview for DSM-IV (SCID) to interview all patients, and the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) to assess obsessive-compulsive symptoms and severity. The onset of OCD symptoms was earlier in males. Major depression was the most common comorbid disorder (30.5%). The most commonly occurring obsessions were contamination (56.7%), aggression (48.9%), and somatic (24.1%), followed by religious (19.9%), symmetry (18.4%), and sexual imagery (15.6%). Symmetry and sexual obsessions, and checking compulsions and rituals, tended to be more common in male patients. Dirt and contamination obsessions and washing compulsions were slightly more common in females. The vast majority of patients with religious obsessions (83%) and half of the patients with sexual obsessions had compulsions that included religious practices. Also, patients with sexual and religious obsessions had delayed seeking professional help. 相似文献

This study aimed to investigate the phenomenology of obsessive–compulsive disorder (OCD), addressing specific questions about the nature of obsessions and compulsions, and to contribute to the World Health Organization's (WHO) revision of OCD diagnostic guidelines. Data from 1001 patients from the Brazilian Research Consortium on Obsessive–Compulsive Spectrum Disorders were used. Patients were evaluated by trained clinicians using validated instruments, including the Dimensional Yale–Brown Obsessive–Compulsive Scale, the University of Sao Paulo Sensory Phenomena Scale, and the Brown Assessment of Beliefs Scale. The aims were to compare the types of sensory phenomena (SP, subjective experiences that precede or accompany compulsions) in OCD patients with and without tic disorders and to determine the frequency of mental compulsions, the co-occurrence of obsessions and compulsions, and the range of insight. SP were common in the whole sample, but patients with tic disorders were more likely to have physical sensations and urges only. Mental compulsions occurred in the majority of OCD patients. It was extremely rare for OCD patients to have obsessions without compulsions. A wide range of insight into OCD beliefs was observed, with a small subset presenting no insight. The data generated from this large sample will help practicing clinicians appreciate the full range of OCD symptoms and confirm prior studies in smaller samples the degree to which insight varies. These findings also support specific revisions to the WHO's diagnostic guidelines for OCD, such as describing sensory phenomena, mental compulsions and level of insight, so that the world-wide recognition of this disabling disorder is increased. 相似文献

BACKGROUND: This study investigated which categories of obsessive-compulsive and Tourette-related behaviors in Gilles de la Tourette's disorder and obsessive-compulsive disorder (OCD) without tics are experienced as most severe across the study groups and what the differences are in symptom distribution between the study groups. METHOD: Fourteen subjects with both Tourette's disorder and OCD, 18 subjects with Tourette's only, 21 subjects with OCD (no tics), and 29 control subjects were studied using a semistructured interview designed to equally assess Tourette- and OCD-related behaviors according to DSM-III-R criteria. Each reported repetitive behavior was evaluated on the presence of anxiety and on goal-directedness. Anxiety-related items were categorized as obsessions or compulsions and non-anxiety-related items as impulsions. Severity of each reported item was assessed with respect to time per day consumed and amount of distress and interference induced by the item. Following these criteria, each reported item was classified as a symptom, a subthreshold symptom, or just as being present. RESULTS: Across the study groups, obsessions were experienced as more severe than (Tourette-related) impulsions and compulsions. Within the study groups, patients with both Tourette's disorder and OCD reported more symptomatic Tourette-related impulsions, such as mental play, echophenomena, and impulsive or self-injurious behaviors; less overall symptomatic obsessions; and less symptomatic washing than patients with OCD (no tics). The differences among individuals with Tourette's with or without OCD reflected differences in symptom severity rather than differences in symptom distribution. CONCLUSION: Obsessions are more time consuming, distressing, and interfering than compulsions and impulsions. Furthermore, the symptomatic repetitive behaviors were distributed differently among patients with both Tourette's disorder and OCD and patients with OCD (no tics). Patients with Tourette's and OCD are phenomenologically more similar to Tourette's than to OCD. These differences possibly represent differences in underlying pathophysiology between Tourette's and tic-free OCD. 相似文献

Background: Several studies have identified discrete symptom dimensions in obsessive–compulsive disorder (OCD), derived from factor analyses of the individual items or symptom categories of the Yale–Brown Obsessive–Compulsive Scale Symptom Checklist (YBOCS‐SC). This study aims to extend previous work on the relationship between obsessions and compulsions by specifically including mental compulsions and reassurance‐seeking. Because these compulsions have traditionally been omitted from prior factor analytic studies, their association to what have been called “pure obsessions” may have been overlooked. Method: Participants ( N =201) were recruited from two multi‐site randomized clinical treatment trials for OCD. The YBOCS‐SC was used to assess OCD symptoms, as it includes a comprehensive list of obsessions and compulsions, arranged by content category. Each category was given a score based on whether symptoms were present and if the symptom was a primary target of clinical concern, and a factor analysis was conducted. Mental compulsions and reassurance‐seeking were considered separate categories for the analysis. Results: Using an orthogonal geomin rotation of 16 YBOCS‐SC categories/items, we found a five‐factor solution that explained 67% of the total variance. Inspection of items that composed each factor suggests five familiar constructs, with mental compulsions and reassurance‐seeking included with sexual, aggressive, and religious obsessions (unacceptable/taboo thoughts). Conclusions: This study suggests that the concept of the “pure obsessional” (e.g., patients with unacceptable/taboo thoughts yet no compulsions) may be a misnomer, as these obsessions were factorially associated with mental compulsions and reassurance‐seeking in these samples. These findings may have implications for DSM‐5 diagnostic criteria. Depression and Anxiety, 2011. © 2011 Wiley‐Liss, Inc. 相似文献
