Long-term effectiveness and cost-effectiveness of guided internet-based cognitive behavioral therapy for obsessive-compulsive disorder: 24-month follow-up. Internet Interv 2024; 35:100725. [PMID: 38362159 PMCID: PMC10867335 DOI: 10.1016/j.invent.2024.100725] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/28/2023] [Revised: 01/09/2024] [Accepted: 02/07/2024] [Indexed: 02/17/2024] Open
Abstract
This study investigated the long-term effectiveness and cost-effectiveness of guided internet-based cognitive behavioral therapy (ICBT) for obsessive-compulsive disorder (OCD). Twenty-five patients with OCD who had undergone guided ICBT in a randomized controlled trial or a single-arm trial were followed up for 6, 12, and 24 months. Missing data were imputed using the mice package in R, and a one-way analysis of variance with repeated measures was performed. The total Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) score significantly decreased from baseline to all endpoints (p < 0.001). OCD remission (the total Y-BOCS score < 14) rates significantly increased from post-treatment (48 %) at the 12 months (80 %) and 24 months (76 %) follow-up (χ2 (1) = 7.11-11.08, p < 0.01) post guided ICBT. Regression analysis predicted the maintenance of remission at 12 and 24 months following post-treatment remission (z = 2.20, p = 0.03). An incremental cost-effectiveness ratio was calculated to assess the cost-effectiveness of guided ICBT. The incremental cost-effectiveness ratio was JPY 999,495, below the JPY 5 million threshold for willingness to pay in Japan. Our findings demonstrate the long-term effectiveness and cost-effectiveness of guided ICBT for OCD. Guided ICBT can mitigate the severity of OCD even after treatment.

Anxiety during the long-term course of obsessive-compulsive disorder. J Affect Disord 2024; 345:311-319. [PMID: 37838266 DOI: 10.1016/j.jad.2023.10.078] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/06/2023] [Revised: 09/22/2023] [Accepted: 10/09/2023] [Indexed: 10/16/2023]
Abstract
OBJECTIVE The study aimed to investigate anxiety and its relation with obsessive-compulsive symptoms during the long-term course of obsessive-compulsive disorder (OCD). METHODS We used data from the Netherlands OCD Association (NOCDA) study, which included 419 participants with OCD (aged 18-79 years). Severity of obsessive-compulsive symptoms and anxiety at baseline and after two, four, and six years were entered into three models, which were analyzed using structural equation modeling: 1) the cross-lagged model, which assumes that anxiety and obsessive-compulsive symptoms are two distinct groups of symptoms interacting directly on the long-term; 2) the stable traits model, which assumes that anxiety and obsessive-compulsive symptoms result from two distinct latent factors, which are stable over the time and interact with each other; and 3) the common factor model, which assumes that anxiety and obsessive-compulsive symptoms are presentations of the same latent factor. RESULTS The cross-lagged model and the stable traits model both were valid models with a good model fit. The common factor model had a poor model fit and was rejected. LIMITATIONS The duration of OCD varied widely between the participants (0-64 years). The majority experienced obsessive-compulsive symptoms since several years, which may have affected results on the course of anxiety and the interaction between anxiety and obsessive-compulsive symptoms. CONCLUSIONS Anxiety and obsessive-compulsive symptoms in OCD patients do not result from a shared underlying factor but are distinct, interacting symptom groups, probably interacting by distinct latent factors.

Predictors of the 6-year outcome of obsessive-compulsive disorder: Findings from the Netherlands Obsessive-Compulsive Disorder Association study. Aust N Z J Psychiatry 2023; 57:1443-1452.

Abstract
OBJECTIVE Obsessive-compulsive disorder is characterized by a chronic course that can vary between patients. The knowledge on the naturalistic long-term outcome of obsessive-compulsive disorder and its predictors is surprisingly limited. The present research was designed to identify clinical and psychosocial predictors of the long-term outcome of obsessive-compulsive disorder. METHODS We included 377 individuals with a current diagnosis of obsessive-compulsive disorder, who participated in the Netherlands Obsessive Compulsive Disorder Association study, a multicenter naturalistic cohort study. Predictors were measured at baseline using self-report questionnaires and clinical interviews. Outcome was assessed using the Yale-Brown Obsessive Compulsive Scale at 2-, 4- and 6-year follow-up. RESULTS The overall course of obsessive-compulsive disorder was characterized by two prominent trends: the first reflected an improvement in symptom severity, which was mitigated by the second, worsening trend in the long term. Several determinants affected the course variations of obsessive-compulsive disorder, namely, increased baseline symptom severity, late age of onset, history of childhood trauma and autism traits. CONCLUSION The long-term outcome of obsessive-compulsive disorder in naturalistic settings was characterized by an overall improvement in symptom severity, which was gradually halted to the point of increased worsening. However, after 6 years, the severity of symptoms remained below the baseline level. While certain determinants predicted a more favorable course, their effect diminished over time in correspondence to the general worsening trend. The results highlight the importance of a regular and continuous monitoring for symptom exacerbations as part of the management of the obsessive-compulsive disorder, regardless of the presence of putative predictors.

Episodic obsessive-compulsive disorder and bipolar spectrum disorder: new evidence from a large Italian OCD sample. Int J Psychiatry Clin Pract 2023; 27:330-337. [PMID: 37401917 DOI: 10.1080/13651501.2023.2231040] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/03/2022] [Accepted: 06/21/2023] [Indexed: 07/05/2023]
Abstract
OBJECTIVES Obsessive-Compulsive Disorder (OCD) has been considered to be a chronic illness; however, some authors described a subtype of OCD characterised by symptom-free periods of time: Episodic-OCD (E-OCD). Only few studies focussed on this subtype of the disorder. The objectives of this research were to study the association between the episodic course of the disorder and lifetime psychiatric comorbidities and to investigate socio-demographic and other clinical features correlated to the episodic course. METHODS The sample is composed of adult OCD patients. The course was defined episodic when at least one circumscribed symptom-free interval of at least 6 months was present. The sample was divided into two subgroups: Episodic-OCD and Chronic-OCD. Differences between groups were analysed with Student's t-test, χ2 tests, Fisher test and multivariate logistic regression. RESULTS Data regarding 585 individuals were collected. 14.2% (N = 83) of our sample had an episodic course. Bipolar I comorbid disorder, abrupt onset, lower severity of illness and lower rates of repeating compulsions were associated with the likelihood of having an E-OCD. CONCLUSIONS Our findings confirm that a significant proportion of OCD patients have an episodic course and that E-OCD could represent a specific endophenotype.

Mixed results for exposure and response prevention therapy in mixed reality for patients with contamination-related obsessive-compulsive disorder: A randomized controlled pilot study. J Clin Psychol 2023; 79:2317-2336. [PMID: 37317567 DOI: 10.1002/jclp.23550] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2022] [Revised: 03/22/2023] [Accepted: 05/28/2023] [Indexed: 06/16/2023]
Abstract
INTRODUCTION Technology-supported exposure and response prevention (ERP) for patients with obsessive-compulsive disorder (OCD) as tested in clinical research, holds promise but also has limitations. The present study aims to overcome these limitations by using mixed reality for ERP (MERP). The objectives of this pilot study were to evaluate the safety, feasibility, and acceptance of MERP and to identify possible obstacles. METHODS Twenty inpatients with contamination-related OCD were recruited and randomized to two conditions: MERP (six sessions in 3 weeks) and care as usual treatment. Patients were assessed before treatment (baseline), after the 3-week intervention period (post), as well as 3 months after post assessment (follow-up) regarding symptomatology (Y-BOCS). RESULTS Results showed a similar reduction in symptomatology in both groups from baseline to post. Regarding safety, no clinically significant deterioration was detected in the MERP group. Patients' evaluation of the MERP was heterogeneous. The qualitative feedback provided helpful indications for further development of the software. Sense of presence was below the midpoint of the scales. CONCLUSION This is the first study evaluating a MERP for patients with OCD that shows cautious evidence for the acceptance and safety of MERP. The results of the subjective evaluation suggest revisions of the software.

Phenomenological Considerations of the World of the Obsessive Patient. J Clin Med 2023; 12:4193.

Abstract
Despite significant scientific advances in research on obsessive-compulsive disorder (OCD), the psychological and behavioral symptoms of this pathological condition remain hard to understand, until they seem paradoxical. The present work seeks to consider the significance and potential contribution of a phenomenological reading of OCD and how phenomenalism has influenced some cognitive models of this disorder. Transcendental phenomenology is a philosophical approach that attaches primary importance to intuitive experience and considers all phenomena intrinsically associated with the subject's inner world. Thus, the subject's intuition is considered the starting point for understanding their essential experience. This approach has had a profound influence on modern cognitive sciences. Among current cognitive models, post-rationalist cognitivism and cognitive neuropsychological psychotherapy seem most effective in capturing the world experiences of OCD patients. Both apply a phenomenological approach to identify these experiences, which are typically characterized by hyper-reflexivity, at the expense of 'natural evidence.' The models have found that OCD patients experience the world emotionally as a sterile set of rules, and this experience determines their suffering.

Efficacy of exposure and response prevention therapy in mixed reality for patients with obsessive-compulsive disorder: study protocol for a randomized controlled trial. BMC Psychol 2023; 11:113. [PMID: 37055854 PMCID: PMC10100604 DOI: 10.1186/s40359-023-01116-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/13/2023] [Accepted: 03/07/2023] [Indexed: 04/15/2023] Open
Abstract
Many patients with obsessive-compulsive disorder (OCD) do not receive cognitive behavioral therapy with exposure and response prevention (first line treatment for OCD), for example, due to patients' fear of the exposure and reservations of the therapists. Technology-supported exposure (e.g., exposure therapy with response prevention in mixed reality [MERP]) for patients with OCD may help to overcome this obstacle. Building upon findings of our pilot study objectives of this study are to evaluate the efficacy, expectations of treatment success, feasibility, and acceptance of MERP as well as to identify possible limitations. In total, 64 outpatients with contamination-related OCD will be recruited and randomized to one of two conditions: MERP (six sessions in six weeks) and self-guided exposure therapy (six exercises in six weeks). Participants will be assessed before (baseline), after the six-week intervention period (post), as well as three months after post assessment (follow-up) regarding symptomatology (Yale-Brown Obsessive Compulsive Scale; Y-BOCS), their subjective evaluation of MERP (acceptance) and sense of presence. The planned study is the first to investigate MERP in patients with OCD.

Clinical characteristics of transformation obsessions in obsessive-compulsive disorder: A psychopathological study. Aust N Z J Psychiatry 2023; 57:130-139.

Abstract
BACKGROUND The obsession of turning into another person (transformation obsessions [TO]), and its related compulsions have been initially conceptualised as a form of mental contamination. Nevertheless, it has remained understudied in the current obsessive-compulsive disorder (OCD) literature. In parallel, disturbances of the self have been identified as markers of prodromal psychosis in patients with schizophrenia. Based on the later association, this study aimed to investigate the sociodemographic and clinical correlates of TO. METHODS In all, 1001 OCD outpatients from the Brazilian OCD Research Consortium were included in this study. Several semi-structured and structured instruments were used to compare 48 OCD patients with TO with 953 OCD patients without TO. A repression model investigated the relationships between the presence of current TO and statistically significant univariate test outcomes. RESULTS Participants with TO presented an overall younger age, a longer period of time between the onset of the OCD symptoms and an OCD diagnosis, greater severity of the sexual/religious dimension and increased suicidality symptoms. CONCLUSIONS These results indicate that TO may be better conceptualised as a form of forbidden/taboo thoughts rather than contamination. While no significant associations with psychotic features (e.g. decreased insight) were observed, TO patients displayed increased suicidality, overall younger age and a significantly larger disparity between seeking treatment and OCD diagnosis. This demonstrates that further clinical awareness and research into TO as an OCD symptom is most needed.

Abstract
Obsessive-compulsive disorder (OCD) is a common psychiatric condition that results in significant distress and impairment, and high societal costs. OCD is widely considered to be a chronic condition, however, our understanding of the chronicity of the disorder, and the incidence of spontaneous remission, has largely relied on longitudinal studies of individuals who have received treatment. The aim of the current study is to examine symptom improvement and rate of spontaneous remission in individuals with OCD who were assigned to a no-treatment control group within a randomized controlled trial using a meta-analytic approach. Twelve studies (n = 282; mean age = 35.52; 60.03 % female) were included in the meta-analysis. The pooled within-group effect size was negligible (g = -0.14; 95 % CI [-0.25, -0.04]) and only 4 % of participants demonstrated spontaneous remission across an average of 10.92 weeks (event rate = 0.04; [95 % CI: 0.01, 0.11]). Sample size and duration of OCD symptoms significantly moderated the effect size for symptom change. No moderators were found for symptom remission. The findings add to the small body of literature demonstrating that OCD has a chronic and unremitting course without treatment.

Abstract
Obsessive-compulsive disorder (OCD) is frequent and often disabling. Yet, correct diagnosis and appropriate treatment implementation are usually delayed, with undesirable consequences. In this paper we review the rationale for early intervention in OCD and provide recommendations for early intervention services. Two scenarios are discussed, i.e., subclinical (prodromal) obsessive-compulsive symptoms (OCS) and full-blown OCD. Although the typical patient with OCD reports a long history of subclinical OCS, longitudinal studies suggest most individuals with OCS in the community do not convert to full-blown OCD. Thus, research on "at risk" phenotypes for OCD and how they should incorporate different risk factors (e.g., polygenic risk scores) are badly needed. For this specific scenario, preventative treatments that are cheap, well tolerated and highly scalable (e.g., lifestyle interventions) are of major interest. On the other hand, increasing evidence suggests OCD to be a progressive disorder and the severity and duration of illness to be associated with both biological changes and increased clinical complexity, including greater number of physical and psychiatric comorbidities, increased family accommodation and worse treatment response. Therefore, prompt identification and early treatment implementation for full-blown OCD are also critical for ethical, clinical and therapeutic reasons. Based on the existing findings, we argue that, regardless of focusing on subclinical OCS or clinical OCD, early intervention services need to target a childhood age group. In addition to delivering well established treatments to people with full-blown OCD early on their illness, early intervention services also need to provide psychoeducation for patients, families and teachers.

Abstract
INTRODUCTION Obsessive-compulsive disorder (OCD) is a prevalent and disabling condition with frequent chronic course. Staging models applied to psychiatric disorders seek to define their extent of progression at a particular time-point and differentiate early, milder clinical phenomena from those characterizing illness progression and chronicity. In OCD patients, a staging model has been recently proposed but not tested yet. This was the aim of the present study. METHODS From an overall sample of 198 OCD patients, recruited across two psychiatric clinics in Northern Italy, 70 patients on stable treatment completed a follow-up assessment ranging from 12 to 24 months. At follow-up initiation, patients had been divided into four staging groups, according to the model proposed by Fontenelle and Yucel. At the end of the follow-up, patients were subdivided into three groups (no stage change, improved stage, or worsened stage) compared with statistical analyses. RESULTS At the end of the follow-up, 67.1% patients showed no stage changes, 24.3% a stage improvement, and 8.6% a stage progression. Worsened patients showed higher rates of comorbid disorders and higher rates of unfavorable employment characteristics compared to the other subgroups (P < .05). Patients with worsened stage showed higher prevalence of somatic obsessions (P < .05), while patients with improved stage showed higher rates of magical thinking and violence/harm obsessions compared to other groups (P < .05). DISCUSSION The present results provide epidemiologic and clinical correlates of the first application of a staging model in a sample of OCD patients, encouraging further studies to assess the utility of this approach in the field.

Immunological causes of obsessive-compulsive disorder: is it time for the concept of an "autoimmune OCD" subtype? Transl Psychiatry 2022; 12:5.

Abstract
Obsessive-compulsive disorder (OCD) is a highly disabling mental illness that can be divided into frequent primary and rarer organic secondary forms. Its association with secondary autoimmune triggers was introduced through the discovery of Pediatric Autoimmune Neuropsychiatric Disorder Associated with Streptococcal infection (PANDAS) and Pediatric Acute onset Neuropsychiatric Syndrome (PANS). Autoimmune encephalitis and systemic autoimmune diseases or other autoimmune brain diseases, such as multiple sclerosis, have also been reported to sometimes present with obsessive-compulsive symptoms (OCS). Subgroups of patients with OCD show elevated proinflammatory cytokines and autoantibodies against targets that include the basal ganglia. In this conceptual review paper, the clinical manifestations, pathophysiological considerations, diagnostic investigations, and treatment approaches of immune-related secondary OCD are summarized. The novel concept of "autoimmune OCD" is proposed for a small subgroup of OCD patients, and clinical signs based on the PANDAS/PANS criteria and from recent experience with autoimmune encephalitis and autoimmune psychosis are suggested. Red flag signs for "autoimmune OCD" could include (sub)acute onset, unusual age of onset, atypical presentation of OCS with neuropsychiatric features (e.g., disproportionate cognitive deficits) or accompanying neurological symptoms (e.g., movement disorders), autonomic dysfunction, treatment resistance, associations of symptom onset with infections such as group A streptococcus, comorbid autoimmune diseases or malignancies. Clinical investigations may also reveal alterations such as increased levels of anti-basal ganglia or dopamine receptor antibodies or inflammatory changes in the basal ganglia in neuroimaging. Based on these red flag signs, the criteria for a possible, probable, and definite autoimmune OCD subtype are proposed.

Abstract
BACKGROUND It remains unknown whether the duration of untreated illness (DUI) may play a critical role in clinical improvement of patients with obsessive-compulsive disorder (OCD). Using a relatively large sample of subjects with OCD, this study investigated the potential impact of the DUI on patients' clinical course and long-term treatment response. METHODS Two hundred and seven patients with OCD recruited by the OCD outpatient clinic of our university hospital participated in the study. The sample was divided into two groups according to the median DUI (DUI≤3 years and DUI >3 years). Patients were treated with selective serotonin reuptake inhibitors or venlafaxine for 48 weeks in open-label conditions. Treatment response and other clinical variables were analysed. RESULTS The total sample showed a mean (SD) DUI of 4.07 (3.5) years, and the mean (SD) illness duration was 6.27 (6.5) years. More than half of the patients had not been treated before (56.5% for OCD). With a median of 3 years as cutoff DUI, response rates were found to be significantly higher in subjects with a short DUI (p < 0.001). Regression analyses showed that a short (≤3 years) DUI and later age at onset predicted better response and higher Y-BOCS scores percentage changes at the endpoint of 48 weeks (β = -1.11, p = 0.003). In addition, there was no correlation between DUI and age of onset in the total patients (r = -0.13, p>0.05). CONCLUSIONS This preliminary study suggests associations between a shorter duration of untreated OCD and favourable long-term outcomes, and a longer DUI with a worse clinical course.

Abstract
Obsessive-Compulsive Disorder (OCD) is a leading cause of disability world-wide (World Health Organization, 2008). Treatment of OCD is a specialized field whose aim is recovery from illness for as many patients as possible. The evidence-based psychotherapeutic treatment for OCD is specialized cognitive behavior therapy (CBT, NICE, 2005, Koran and Simpson, 2013). However, these treatments are not accessible to many sufferers around the world. Currently available guidelines for care are deemed to be essential but insufficient because of highly variable clinician knowledge and competencies specific to OCD. The phase two mandate of the 14 nation International OCD Accreditation Task Force (ATF) created by the Canadian Institute for Obsessive Compulsive Disorders is development of knowledge and competency standards for specialized treatments for OCD through the lifespan deemed by experts to be foundational to transformative change in this field. This paper presents knowledge and competency standards for specialized CBT for adult OCD developed to inform, advance, and offer a model for clinical practice and training for OCD. During upcoming ATF phases three and four criteria and processes for training in specialized treatments for OCD through the lifespan for certification (individuals) and accreditation (sites) will be developed based on the ATF standards.

Abstract
The aim of this study is to examine the association of autism traits with long-term obsessive compulsive disorder (OCD) symptoms and well-being levels in patient with OCD. Participants comprised 18 outpatients from a tertiary hospital and 100 adults who were registered in a large Japanese internet marketing research company and met OCD criteria by the Mini-International Neuropsychiatric Interview and were between the ages of 20 and 65 years. Clinical characteristics, autism trait assessed using the Autism Spectrum Quotient (AQ), OCD symptoms assessed using Yale-Brown Obsessive-Compulsive Scale (Y-BOCS), and well-being assessed using the Flourishing Scale were assessed. Multiple regression analyses showed that a greater total score of AQ, a greater subscale score "imagination" was associated with a greater score of Y-BOCS. Greater total score of AQ, a greater subscale score "social skill," and "imagination" were associated with lower well-being score. Autism traits, especially lack of imagination, were associated with more severe OCD symptoms. Further, autism traits, especially social skill problems and lack of imagination, were associated with lower levels of well-being. Assessment of autism traits before treatment and a strategy designed for OCD patients with autism traits may be warranted.

Abstract
AbstractMore than 50% of patients with obsessive-compulsive disorder (OCD) do not receive first-line psychological treatment such as cognitive-behavioral therapy with exposure and response prevention. To narrow this treatment gap, there is an urgent need for therapies that are easy to disseminate and highly accepted by patients. The aim of the present pilot study was to evaluate the effectiveness of the Metacognitive Group Training for OCD (MCT-OCD). Fifty patients with OCD participated in the MCT-OCD for 4 weeks during their inpatient stay in a single-arm pilot trial. Patients were assessed before and after the intervention and filled out an online survey 6 months after post assessment. Results showed a decrease in obsessive compulsive symptoms according to the Yale-Brown Obsessive Compulsive Scale (primary outcome) from baseline to post assessment with a large effect size. Symptom reduction remained stable over 6 months and was positively correlated with appraisal ratings of the training. The reduction in frequency of obsessive compulsive symptoms, distress due to obsessive compulsive symptoms, cognitive biases, and depressive symptoms remained stable over 6 months after the intervention. Our findings tentatively imply that the MCT-OCD is a promising treatment for OCD patients. A randomized controlled trial is thus warranted to further clarify the efficacy of the MCT-OCD. Trial Registration: German Clinical Trials Register (DRKS-ID: DRKS00012531), date of registration: 16.06.2017.

Abstract
BACKGROUND A high number of patients with obsessive-compulsive disorder (OCD) do not receive cognitive-behavioral therapy with exposure and response prevention, which is the most effective treatment for OCD. Therefore, Metacognitive Training for OCD (MCT-OCD) was developed, which is a structured group therapy aiming at the modification of dysfunctional (meta-)cognitive biases, beliefs and coping styles. It can be administered by less trained personnel, thus may reach a higher number of patients. An uncontrolled pilot study (MCT-OCD pilot version) provided first evidence that the training is highly accepted by patients; OC symptoms decreased with a high effect size (η2partial = 0.50). The aim of the present study is to address the shortcomings of the pilot study (e.g., no control group) and to assess the efficacy of the revised version of the MCT-OCD in the framework of a randomized controlled trial. METHODS Eighty patients with OCD will be recruited. After a blinded assessment at baseline (-t1), patients will be randomly assigned either to the intervention group (MCT-OCD; n = 40) or to a care as usual control group (n = 40). The MCT-OCD aims to enhance patients' metacognitive competence in eight modules by addressing dysfunctional (meta-)cognitive biases and beliefs associated with OCD (e.g., intolerance of uncertainty). After 8 weeks, patients will be invited to a post assessment (t1), and then they will receive a follow-up online questionnaire 3 months following t1 (t2). The primary outcome is the Y-BOCS total score, and the secondary outcomes include the HDRS, OCI-R, OBQ-44, MCQ-30, WHOQOL-BREF, BDI-II, and subjective appraisal ratings of the MCT-OCD. We expect that OC symptoms will decrease more in the intervention group compared with the care as usual control group from -t1 to t1 and that treatment gains will be maintained until t2. DISCUSSION The planned study is the first to investigate the MCT-OCD, a promising new treatment, in a randomized controlled trial. The MCT-OCD may help to overcome existing treatment barriers for patients with OCD. TRIAL REGISTRATION German Registry for Clinical Studies ( DRKS00013539 ), 22.02.2018.

Childhood trauma and attachment style predict the four-year course of obsessive compulsive disorder: Findings from the Netherlands obsessive compulsive disorder study. J Affect Disord 2020; 264:206-214. [PMID: 32056752 DOI: 10.1016/j.jad.2019.12.028] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/21/2019] [Revised: 12/08/2019] [Accepted: 12/19/2019] [Indexed: 01/20/2023]
Abstract
INTRODUCTION Obsessive compulsive disorder (OCD) is a chronic psychiatric disorder where most patients do not reach full symptomatic remission. Identifying predictors of course can improve patients' care by informing clinicians on prognosis and enhancing treatment strategies. Several predictors associated with improved outcome of OCD were identified. However, research focused mainly on clinical, illness-related predictors of the course of OCD. This study examined the contribution of environmental and interpersonal predictors on the long-term outcome of OCD, in addition to the previously identified clinical indicators. METHODS We used the baseline, two and four-year data of 382 adult OCD patients participating in the naturalistic cohort study of the Netherlands Obsessive Compulsive Disorder Association (NOCDA). Remission was assessed using the Yale-Brown Obsessive Compulsive Scale (Y-BOCS). Predictors of outcome were assessed at baseline, via clinician-rated and self-report instruments. RESULTS Remission at two and at four-year follow-up ranged from 11% to 26%. Early age of onset and the presence of childhood trauma predicted a worse four-year course. Secure attachment style emerged as a protective predictor of improved outcome. LIMITATIONS The naturalistic design of our study did not enable a systematic estimation the effect of treatments received during the follow-up period. Furthermore, age of onset and childhood trauma were assessed retrospectively, which may contribute to recall bias. CONCLUSION Results coincide with previous prediction research and stress the importance of adaptive interpersonal functioning in the course of OCD. Clinical implications and future research directions are discussed.

Abstract
IMPORTANCE Cognitive behavioral therapy is recommended for anxiety-related disorders, but evidence for its long-term outcome is limited. OBJECTIVE This systematic review and meta-analysis aimed to assess the long-term outcomes after cognitive behavioral therapy (compared with care as usual, relaxation, psychoeducation, pill placebo, supportive therapy, or waiting list) for anxiety disorders, posttraumatic stress disorder (PTSD), and obsessive-compulsive disorder (OCD). DATA SOURCES English-language publications were identified from PubMed, PsycINFO, Embase, Cochrane, OpenGrey (1980 to January 2019), and recent reviews. The search strategy included a combination of terms associated with anxiety disorders (eg, panic or phobi*) and study design (eg, clinical trial or randomized controlled trial). STUDY SELECTION Randomized clinical trials on posttreatment and at least 1-month follow-up effects of cognitive behavioral therapy compared with control conditions among adults with generalized anxiety disorder, panic disorder with or without agoraphobia, social anxiety disorder, specific phobia, PTSD, or OCD. DATA EXTRACTION AND SYNTHESIS Researchers independently screened records, extracted statistics, and assessed study quality. Data were pooled using a random-effects model. MAIN OUTCOMES AND MEASURES Hedges g was calculated for anxiety symptoms immediately after treatment and at 1 to 6 months, 6 to 12 months, and 12 months or more after treatment completion. RESULTS Of 69 randomized clinical trials (4118 outpatients) that were mainly of low quality, cognitive behavioral therapy compared with control conditions was associated with improved outcomes after treatment completion and at 1 to 6 months and at 6 to 12 months of follow-up for a generalized anxiety disorder (Hedges g, 0.07-0.40), panic disorder with or without agoraphobia (Hedges g, 0.22-0.35), social anxiety disorder (Hedges g, 0.34-0.60), specific phobia (Hedges g, 0.49-0.72), PTSD (Hedges g, 0.59-0.72), and OCD (Hedges g, 0.70-0.85). At a follow-up of 12 months or more, these associations were still significant for generalized anxiety disorder (Hedges g, 0.22; number of studies [k] = 10), social anxiety disorder (Hedges g, 0.42; k = 3), and PTSD (Hedges g, 0.84; k = 5), but not for panic disorder with or without agoraphobia (k = 5) and could not be calculated for specific phobia (k = 1) and OCD (k = 0). Relapse rates after 3 to 12 months were 0% to 14% but were reported in only 6 randomized clinical trials (predominantly for panic disorder with or without agoraphobia). CONCLUSIONS AND RELEVANCE The findings of this meta-analysis suggest that cognitive behavioral therapy for anxiety-related disorders is associated with improved outcomes compared with control conditions until 12 months after treatment completion. At a follow-up of 12 months or more, effects were small to medium for generalized anxiety disorder and social anxiety disorder, large for PTSD, and not significant or not available for other disorders. High-quality randomized clinical trials with 12 months or more of follow-up and reported relapse rates are needed.

Directionality of change in obsessive compulsive disorder (OCD) and suicidal ideation over six years in a naturalistic clinical sample ✰. J Affect Disord 2019; 245:841-847. [PMID: 30699868 PMCID: PMC6361538 DOI: 10.1016/j.jad.2018.11.006] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/11/2018] [Revised: 09/17/2018] [Accepted: 11/02/2018] [Indexed: 12/22/2022]
Abstract
BACKGROUND Obsessive compulsive disorder (OCD) is associated with elevated suicide risk, but the directionality of the association between OCD severity and suicidal ideation has not been established, which was the goal of this study. METHODS Participants (n = 325) were adults with either a current or past diagnosis of Diagnostic and Statistical Manual of Mental Disorders, 4th Edition (DSM-IV) OCD who were assessed annually for suicidal ideation and OCD symptom severity for six years. Cross-lagged panel analyses statistically compared unidirectional and bidirectional models over time. Serious suicide-related adverse events were reported. RESULTS The best-fitting and most parsimonious model included paths predicting suicidal ideation from OCD symptom severity, but not vice versa. These results were confirmed by comparing a model with cross-lagged paths constrained equal to a freely estimated model. Higher OCD symptom severity in a given year was associated with a higher suicidal ideation severity in the subsequent year. Five suicide-related adverse events were reported throughout the duration of the study, including two suicide deaths and three suicide attempts. LIMITATIONS The study relied on a single-item, annual measure of suicidal ideation in adults, with substantial variability in severity of suicide risk, and missing data increased with later observations in the study. DISCUSSION OCD symptom severity predicted next year suicidal ideation severity. In contrast, suicidal ideation severity in a given year did not predict next-year OCD symptom severity in this OCD sample. Thus, rather than waiting for suicidal ideation to resolve, clinicians should consider providing empirically supported treatments for OCD.

A Clinical Staging Model for Obsessive-Compulsive Disorder: Is It Ready for Prime Time? EClinicalMedicine 2019; 7:65-72. [PMID: 31193644 PMCID: PMC6537549 DOI: 10.1016/j.eclinm.2019.01.014] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/09/2018] [Revised: 01/30/2019] [Accepted: 01/30/2019] [Indexed: 01/02/2023] Open
Abstract
Recent changes to the diagnostic classification of obsessive-compulsive disorder (OCD), including its removal from the anxiety/neurotic, stress-related and somatoform disorders chapters of the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) and International Classification of Diseases 11th Revision (ICD-11), are based on growing evidence of unique pathogenic signatures and linked diagnostic and treatment approaches. In this review, we build on these recent developments and propose a 'clinical staging model' of OCD that integrates the severity of symptoms and phase of illness for personalised case management. A clinical staging model is especially relevant for the early identification and management of subthreshold OCD - a substantial and largely neglected portion of the population who, despite having milder symptoms, experience harms that may impact personal relationships, work-related functioning and productivity. Research on the pathogenesis, classification and management of such cases is needed, including the development of new outcomes measures that prove sensitive to changes in future clinical trials. Early intervention strategies in OCD are likely to yield better long-term outcomes.
