Despite the existence of efficacious cognitive-behavioral group treatments for obsessive-compulsive disorder (OCD), no data has been presented regarding the potential impact of symptom or thematic similarity among group members. The purpose of this study was to evaluate the effect of thematic similarity among group members on outcome after cognitive-behavioral (CBT) or exposure/response prevention (ERP) treatment for OCD. Results consistently demonstrated across a range of measures no impact of thematic similarity, nor any interaction of similarity by treatment type (ERP versus CBT), on treatment outcome. These data suggest that OCD treatment groups can be formed based on consecutive client intake without negatively impacting efficacy. 相似文献

Background: The present study sought to identify predictors of outcome for a comprehensive cognitive therapy (CT) developed for patients with obsessive–compulsive disorder (OCD). Methods: Treatment was delivered over 22 sessions and included standard CT methods, as well as specific strategies designed for subtypes of OCD including religious, sexual, and other obsessions. This study of 39 participants assigned to CT examined predictors of outcomes assessed on the Yale‐Brown Obsessive Compulsive Scale. A variety of baseline symptom variables were examined as well as treatment expectancy and motivation. Results: Findings indicated that participants who perceived themselves as having more severe OCD at baseline remained in treatment but more severe symptoms were marginally associated with worse outcome for those who completed therapy. Depressed and anxious mood did not predict post‐test outcome, but more Axis I comorbid diagnoses (mainly major depression and anxiety disorders), predicted more improvement, as did the presence of sexual (but not religious) OCD symptoms, and stronger motivation (but not expectancy). A small rebound in OCD symptoms at 1‐year follow‐up was significantly predicted by higher scores on personality traits, especially for schizotypal (but not obsessive–compulsive personality) traits. Conclusions: Longer treatment may be needed for those with more severe symptoms at the outset. CT may have positive effects not only on OCD symptoms but also on comorbid depressive and anxious disorders and associated underlying core beliefs. Findings are discussed in light of study limitations and research on other predictors. Depression and Anxiety, 2011. © 2011 Wiley‐Liss, Inc. 相似文献

Objective: To examine whether obsessive‐compulsive disorder (OCD) symptom subtypes are associated with response rates to cognitive‐behavioural therapy (CBT) among pediatric patients. Method: Ninety‐two children and adolescents with OCD (range = 7–19 years) received 14 sessions of weekly or intensive (daily psychotherapy sessions) family‐based CBT. Assessments were conducted at baseline and post‐treatment. Primary outcomes included scores on the Children’s Yale‐Brown Obsessive‐Compulsive Scale (CY‐BOCS), remission status, and ratings on the Clinical Global Improvement (CGI) and Clinical Global Impression – Severity (CGI‐Severity) scales. Results: Seventy‐six per cent of study participants (n = 70) were classified as treatment responders. Patients with aggressive/checking symptoms at baseline showed a trend (P = 0.06) toward improved treatment response and exhibited greater pre/post‐treatment CGI‐Severity change than those who endorsed only non‐aggressive/checking symptoms. Step‐wise linear regression analysis indicated higher scores on the aggressive/checking dimension were predictive of treatment‐related change in the CGI‐Severity index. Regression analysis with CY‐BOCS score as the dependent variable showed no difference between OCD subtypes. Conclusion: Response to CBT in pediatric OCD patients does not differ substantially across subtypes. 相似文献

Prior research supports the distinction between tic-related and non-tic-related obsessive-compulsive disorder (OCD) based on phenomenologic, etiologic, and neurobehavioral data. The present study examines whether response to psychosocial treatment differs in adolescents, depending on the presence of comorbid tics. Nineteen adolescents, 12-17 years of age, participated in 7-week, uncontrolled trial of group cognitive-behavioral treatment (CBT) for OCD. Eight of the patients had tic-related and eleven had non-tic-related OCD. The group CBT program included psycho-education, exposure and response prevention, cognitive strategies, and family involvement. Significant improvement was observed for all subjects on the Yale-Brown Obsessive Compulsive Scale ratings of obsessions, compulsions, and total OCD symptoms. Outcomes were similar for subjects with tic-related and non-tic-related OCD. These preliminary results suggest that the presence of comorbid tic disorders may not attenuate response to behavioral group treatment among adolescents. 相似文献

OBJECTIVE: This study was designed to prospectively investigate the efficacy and cognitive adverse effects of stereotactic bilateral anterior cingulotomy as a treatment for refractory obsessive-compulsive (OCD) patients for 12 months. METHOD: Patients were eligible if they had severe OCD and rigorous treatments had been unsuccessful. Yale-Brown Obsessive-Compulsive Scale (Y-BOCS), Clinical Global Impression (CGI) and neuropsychological tests were used to assess the efficacy and cognitive changes of cingulotomy before and 12 months after operation. RESULTS: The mean improvement rate of the Y-BOCS scores achieved from baseline was 36.0%. Out of 14 patients six met responder criteria; 35% or higher improvement rate on Y-BOCS and CGI improvement of very much or much better at 12-month follow-up. There was no significant cognitive dysfunction after cingulotomy. CONCLUSION: Anterior cingulotomy shows few cognitive adverse effects, with about half of the OCD patients demonstrating significant symptomatic improvement. 相似文献

Aims: Deep brain stimulation (DBS) of the ventral capsule/ventral striatum (VC/VS) is a promising alternative to ablative surgery in treatment of refractory obsessive–compulsive disorder (OCD). A pilot study was conducted to assess 15‐month outcomes of DBS in patients with refractory OCD in Taiwan. Methods: Four adult patients with a 3‐year or more history of refractory OCD (Yale–Brown Obsessive–Compulsive Scale [Y‐BOCS] score of at least 28) met the criteria for DBS surgery. DBS electrodes were implanted bilaterally in the VC/VS. Stimulation was adjusted for therapeutic benefit and absence of adverse effects. Psychiatric evaluation was conducted preoperatively, postoperatively, and at follow up at every 3 months for 15 months. Primary outcome measure was Y‐BOCS. Secondary outcomes included the Hamilton Depression Rating Scale (HAM‐D), and the Global Assessment of Function Scale. Results: Mean severity of OCD was a Y‐BOCS score of 36.3 ± 2.1. At the end of 15 months' follow up, there was a 33.06% decrease in OCD severity (P = 0.001). Similar findings were seen for HAM‐D (32.51% reduction, P = 0.005), and Global Assessment of Function Scale (31.03% increase, P = 0.026). In terms of adverse effects, two patients suffered from hypomania episodes after several weeks of DBS stimulation, and one had transient hypomania‐like syndrome during DBS initial programming. One patient (Case 1) had an allergic reaction to implantation of the pulse generator in the chest, and another patient (Case 3) exhibited vertigo. Conclusions: We confirm that DBS of the VC/VS appears to be beneficial for improvements in function and mood among patients with treatment‐resistant OCD. Compared to previous studies examining the therapeutic effects of DBS, no serious adverse effects were observed. 相似文献

We describe an adolescent boy's experience of peer victimization and its relation with his development of obsessive-compulsive disorder (OCD). Subsequent to being peer victimized, this boy was seen for 20 sessions of cognitive-behavioral therapy over the course of 4 weeks that followed the protocol outlined by March and Mulle in 1998. Standardized post-treatment assessment indicated significant reductions in OCD, depressive, and anxious symptomatology as compared to baseline. This case illustrates how negative peer experiences may be related to the development and maintenance of OCD. 相似文献

Objective: Behaviour therapy with exposure and response prevention (ERP) or cognitive behavioural therapy (CBT) including ERP are considered the psychological treatments of choice for obsessive–compulsive disorder (OCD), but group CBT/ERP has received relatively little research attention in the treatment of OCD. The aim of this study was to provide a meta‐analysis of the effectiveness of group CBT/ERP for OCD. Method: A systematic literature search was conducted and studies were meta‐analysed by means of the Cochrane Review Manager Program with measures of i) pre‐ to post‐effect sizes (ES) and ii) between‐group ES in comparison with different control conditions. Outcome was primarily measured on the Y‐BOCS and ES was calculated in the form of Cohens d. Results: Thirteen trials were included in the meta‐analysis. The overall pre–post‐ES of these trials of 1.18 and a between‐group ES of 1.12 compared with waiting list control in three randomized controlled studies indicate that group CBT/ERP is an effective treatment for OCD. Group CBT achieved better results than pharmacological treatment in two studies. One study found no significant differences between individual and group CBT. Conclusion: Group CBT is an effective treatment for OCD, but more studies are needed to compare the effectiveness of group and individual treatment formats. 相似文献

OBJECTIVE: The aim of this study was to evaluate the results of cognitive-behavioral group therapy (CBGT) for obsessive-compulsive disorder (OCD) over a 1-year follow-up period. METHOD: Forty-two OCD patients, who completed 12 sessions of CBGT, were followed for 1 year. Measures of the severity of symptoms were obtained at the end of the acute treatment and at 3, 6, and 12 months post-treatment using the Yale-Brown obsessive-compulsive scale (Y-BOCS) and the clinical global impression (CGI). RESULTS: The reduction in the severity of symptoms observed at the end of the treatment was maintained during 1 year (F2,41=1.1; P=0.342). Eleven patients (35.5%) relapsed in the follow-up period. The intensity of improvement (log rank=12.97, GL=1, P=0.0003) and full remission (log rank=6.17; GL=1; P=0.001) were strong predictors for non-relapsing. CONCLUSION: The CBGT is an effective treatment for OCD and its results are maintained for 1 year. However, further long-term randomized controlled trials are needed in order to confirm this finding. 相似文献

We compared early-onset and late-onset obsessive-compulsive disorder (OCD) patients in terms of demographic and clinical features. One hundred sixteen outpatients whose primary diagnosis was OCD according to DSM-IV diagnostic criteria were recruited. Early-onset (n=50) and late-onset (n=66) OCD groups were compared with respect to demographic variables and scores obtained on various scales. A male gender predominance was found in early-onset OCD group. Symmetry/exactness obsessions, religious obsessions, hoarding/saving obsessions, and hoarding/collecting compulsions also were significantly more frequent in the early-onset group than in the late-onset group. The results may suggest a phenotypic difference between the two groups. Further studies are needed to investigate the differences between early-onset and late-onset OCD groups to examine the hypothesis that early-onset OCD is a distinct subtype of the disorder. 相似文献

OBJECTIVE: Two methods for predicting remissions in obsessive-compulsive disorder (OCD) treatment are evaluated. Y-BOCS measurements of 88 patients with a primary OCD (DSM-III-R) diagnosis were performed over a 16-week treatment period, and during three follow-ups. METHOD: Remission at any measurement was defined as a Y-BOCS score lower than thirteen combined with a reduction of seven points when compared with baseline. Logistic regression models were compared with a Cox regression for recurrent events model. RESULTS: Logistic regression yielded different models at different evaluation times. The recurrent events model remained stable when fewer measurements were used. Higher baseline levels of neuroticism and more severe OCD symptoms were associated with a lower chance of remission, early age of onset and more depressive symptoms with a higher chance. CONCLUSION: Choice of outcome time affects logistic regression prediction models. Recurrent events analysis uses all information on remissions and relapses. Short- and long-term predictors for OCD remission show overlap. 相似文献

OBJECTIVE: To review the extant literature on the long-term outcome of child/adolescent-onset obsessive-compulsive disorder (OCD). METHOD: Medline and Psychlit databases were systematically searched for articles regarding long-term outcomes of child/adolescent-onset OCD. Meta-analysis regression was applied to evaluate predictors and persistence of OCD. RESULTS: Sixteen study samples (n = 6-132; total = 521 participants) in 22 studies had follow-up periods ranging between 1 and 15.6 years. Pooled mean persistence rates were 41% for full OCD and 60% for full or subthreshold OCD. Earlier age of OCD onset (z = -3.26, P = 0.001), increased OCD duration (z = 2.22, P = 0.027) and in-patient vs. out-patient status (z = 2.94, P = 0.003) predicted greater persistence. Comorbid psychiatric illness and poor initial treatment response were poor prognostic factors. Although psychosocial function was frequently compromised, most studies lacked comprehensive outcome measures. CONCLUSION: Long-term persistence of pediatric OCD may be lower than believed. Future studies should include broader measures of outcome including symptomatic persistence and functional impairment in multiple domains. 相似文献

In light of current interest in an obsessive-compulsive spectrum of disorders, this study sought to determine whether comorbidity patterns support the unique relationship hypothesized between these conditions and obsessive-compulsive disorder (OCD). Comparisons were made of lifetime rates of several proposed spectrum conditions in individuals with one of three anxiety disorder principal diagnoses (OCD, social phobia, or panic disorder [PD], N=277). Spectrum conditions examined included tic-related disorders, trichotillomania, skin picking, and eating disorders, with analyses performed on rates both of clinical disorder alone, and clinical and subclinical manifestations jointly. The OCD group was found to differ from both other groups in showing 1) a greater proportion of individuals affected with any lifetime spectrum condition, 2) a greater number of lifetime spectrum conditions affecting each individual, and 3) a greater proportion of individuals having a lifetime history of multiple spectrum conditions. Analyses for specific spectrum conditions indicated differences among the anxiety disorder groups for all spectrum categories except eating disorders, though only in the case of tic-related conditions did OCD differ significantly from both comparison groups. For the other conditions, dissimilar patterns of differences were observed among the three groups, particularly when subclinical manifestations were included. These findings have conceptual and clinical implications, including 1) the salience of tic-related disorders in the OC spectrum, 2) the possibility that the relationship between spectrum conditions and anxiety disorders may take several different forms, and 3) the need for refinement of the hypothesized spectrum. 相似文献

The COMT gene has been implicated to be involved in the pathogenesis of obsessive-compulsive disorder (OCD) and various other psychiatric disorders. COMT enzyme activity is governed by a common genetic polymorphism at codon 158 that results in substantial 3- to 4-fold variation in enzymatic activity [a high-activity COMT variant (H) and a low activity variant (L)]. This study evaluates the association between OCD and the COMT gene polymorphism. Fifty-nine OCD patients that were diagnosed according to DSM-IV criteria and 114 healthy control subjects were included in the study. PCR technique was used for molecular analysis. The genotypic pattern of distribution of the COMT gene (H/H, H/L, and L/L genotypes) was not different between the OCD patients and controls. There were no significant differences among the patients with positive family history for OCD, those with negative family history for OCD, and the controls with respect to allele frequencies of the COMT gene polymorphisms. Patients that were homozygous or heterozygous for the L allele had significantly higher insight scores (i.e., poorer insight) on Y-BOCS compared to those homozygous for the H allele. We did not find an association between OCD, family history for OCD, and the COMT gene polymorphism. This study suggests that the COMT gene polymorphism is not directly associated with OCD in our patient group. 相似文献

Kashyap H, Kumar JK, Kandavel T, Reddy YCJ. Neuropsychological correlates of insight in obsessive–compulsive disorder. Objective: There are limited data on neuropsychological correlates of poor insight in obsessive–compulsive disorder (OCD). We hypothesize that poor insight may be associated with greater impairment in tasks of conflict resolution/response inhibition and possibly impairment in a task of verbal learning and memory. Method: Insight and neuropsychological functions were assessed in 150 subjects with DSM‐IV OCD. The neuropsychological data of 177 healthy control subjects were used for comparison. Results: Insight score correlated significantly with the Stroop Interference Test for conflict resolution/response inhibition (P = 0.002), and showed trends for significance with the Controlled Oral Word Association (COWA) average for verbal fluency (P = 0.021) and delayed recall on the Auditory Verbal Learning Test (AVLT) for verbal memory (P = 0.015). On regression analysis, the AVLT delayed recall, the COWA average, the Matrix score, the Yale‐Brown Obsessive–Compulsive Scale total score, and current antipsychotic use emerged as significant predictors of poorer insight. Conclusion: Poor insight is associated with greater impairments in conflict resolution/response inhibition, verbal memory, and fluency. Individuals with poorer insight may have difficulty in appropriately processing conflicting information, updating their memory with corrective information, and then accessing this corrective information to modify their irrational beliefs. 相似文献

OBJECTIVE: Although obsessive-compulsive disorder (OCD) is usually conceptualized as an anxiety disorder some studies suggested it to be a deficit of impulse control. The purpose of this study was to assess impulsiveness in OCD families and compare it to control families. METHOD: Seventy cases and their 139 relatives were compared with 70 controls and their 134 relatives from a German family study on OCD (German Epidemiologic Network for OCD Studies). All subjects were interviewed and diagnosed according DSM-IV criteria and were administered the Barratt Impulsiveness Scale (BIS) and PADUA-Inventory to assess obsessive-compulsive symptoms. RESULTS: OCD subjects had significantly higher scores of cognitive impulsiveness. However, first-degree relatives of OCD cases and of controls had comparable BIS-11 scores. Significant associations of aggressive obsessions and checking with cognitive impulsiveness were found. CONCLUSION: OCD is a severe mental disorder that is characterized by a lack of cognitive inhibition. However, impulsiveness does not represent a familial trait in families of OCD subjects. 相似文献

Background: Exposure and response prevention (ERP) for obsessive–compulsive disorder (OCD) is underutilized, in part because of costs and time requirements. This study extends pilot work investigating the use of a stepped care ERP administration, in which patients are first given a low‐intensity, low‐cost treatment and the more costly intervention is reserved for those who do not respond to the first intervention. Methods: Thirty adults with OCD were randomized to receive stepped care ERP or standard ERP. Those receiving stepped care started with three sessions over 6 weeks of low‐intensity counseling with ERP bibliotherapy; patients failing to meet strict responder criteria after 6 weeks were given the more traditional treatment of therapist‐administered ERP (17 sessions twice weekly). Those receiving standard ERP received the therapist‐administered ERP with no lower‐intensity lead‐in. Results: The two treatments were equally efficacious, with 67% of stepped care completers and 50% of standard treatment completers meeting criteria for clinically significant change at posttreatment. Similarly, no differences in client satisfaction ratings were obtained between the two groups. Examination of treatment costs, however, revealed that stepped care resulted in significantly lower costs to patients and third‐party payers than did standard ERP, with large effect sizes. Conclusions: These results suggest that stepped care ERP can significantly reduce treatment costs, without evidence of diminished treatment efficacy or patient satisfaction. Additional research is needed to determine the long‐term efficacy and costs of stepped care for OCD, and to examine the financial and therapeutic impact of implementing stepped care in community settings.

Our objective in this study was to compare the demographics and clinical characteristics of patients with episodic and chronic obsessive-compulsive disorder (OCD). We recruited 128 outpatients with a primary diagnosis of OCD according to DSM-IV diagnostic criteria. The episodic (n=24) and chronic (n=104) OCD patient groups were compared with respect to demographic variables and scores from various psychiatric rating scales. The severity of compulsions was found to be significantly lower in the episodic OCD group than in the chronic OCD group. When the frequency of Axis I disorders was assessed in the two groups, bipolar disorder was found to have a significantly higher prevalence rate in the episodic OCD group than that in the chronic OCD group. The results of our study point to the possibility of an association between a subgroup of OCD with an episodic course and bipolar disorder. The evidence of such a relationship, which needs to be confirmed in a larger sample, might expand the scope of the clinical assessment and therapy of this subgroup of OCD. 相似文献

OBJECTIVE: Cognitive impairment, more often involving memory and/or executive functions, has been reported in obsessive-compulsive (OC) patients. The present study aimed at: i) replicating, in an independent sample, previous findings by our group showing neurocognitive slowness limited to executive tasks; ii) assessing the influence of deficit in general cognitive abilities on executive dysfunction. METHOD: A comprehensive neuropsychological battery was administered to 30 drug-free OC patients and 30 healthy controls. RESULTS: Obsessive-compulsive patients performed worse on visuospatial tests, were slower on executive tasks, and performed worse on the Wisconsin Card Sorting Test. After covarying for Wechsler Adult Intelligence Scale-Revised performance Intellectual Quotient, a lesser degree of executive dysfunction was observed. CONCLUSION: Obsessive-compulsive patients exhibit an impairment of executive functions, especially when tasks also require visuospatial abilities. The impairment might reflect a hyperactivity of the executive control. 相似文献

OBJECTIVE: Obsessive-compulsive disorder (OCD) is a chronic disabling disease with profound implications for social functioning. Thirty per cent of all patients with OCD show insufficient improvement with state-of-the-art treatment. Conventional treatment and alternative treatment options for this population were investigated. METHOD: A selective review of the relevant scientific literature on OCD treatment and treatment resistance was conducted. RESULTS: In addition to serotonin reuptake inhibitors (SRIs) and cognitive-behavioural therapy, alternative monotherapies, SRI augmentation strategies with a variety of drugs and electroconvulsive therapy have shown results in individual cases, but no conclusive evidence has been found in placebo-controlled trials. While studies investigating neurosurgery for refractory OCD show positive results, most of these studies have methodological shortcomings. CONCLUSION: Novel approaches currently under investigation that have shown promising effects for treatment-resistant OCD include SRI augmentation with atypical antipsychotics and chronic deep brain stimulation, a new surgical technique. Placebo-controlled trials for both treatment options will be needed to confirm preliminary findings. 相似文献
