Reductions in Anxiety are Associated with Decreased Expressive Suppression and Increased Cognitive Reappraisal After Cognitive-Behavioral Treatment: A Naturalistic Study in Youth.

Broad deficits in emotion regulation skills have been observed in children with anxiety-related disorders. These deficits typically improve during cognitive-behavioral therapy (CBT), but few studies have examined changes in expressive suppression and cognitive reappraisal in youth with anxiety disorders and/or obsessive-compulsive disorder (OCD) during CBT, especially in real-world settings. In a naturalistic treatment-seeking sample, 123 youth completed measures of anxiety, depression, and emotion regulation strategy use before and after 15 sessions of CBT. For anxious youth, anxiety and expressive suppression decreased over treatment, while cognitive reappraisal increased. Reductions in expressive suppression and increases in cognitive reappraisal were significantly associated with improvements in anxiety and remained significantly associated with post-treatment anxiety after accounting for baseline anxiety and depression. Changes in expressive suppression and cognitive reappraisal over the course of treatment were not found for youth with primary OCD. Thus, CBT improves emotion regulation abilities in anxious youth, and these improvements are associated with anxiety reduction; improvements in emotion regulation do not appear to drive changes in OCD symptoms. Further research is needed to determine whether changes in emotion regulation strategies mediate changes in anxiety among youth receiving CBT.

An investigation of the role of estradiol in fear reduction during a single session of exposure therapy

ABSTRACT Research suggests that estradiol may moderate fear extinction. It is unclear whether these results generalize to exposure therapy. The aim of the current study was to determine whether estradiol moderates outcomes in exposure therapy among women with anxiety disorders. Participants were 35 women with a primary diagnosis of an anxiety disorder who participated in the study as part of routine care at an anxiety specialty clinic. Endogenous estradiol was assessed via saliva. They provided subjective distress ratings before (pre) and after (post) an exposure session, as well as after a brief delay (recall). Contrary to predictions, there were no significant differences in exposure outcomes between the high and low estradiol groups. However, among participants with primary obsessive-compulsive disorder (OCD), results were partially consistent with the hypotheses. Women with lower estradiol initially demonstrated more improvement in subjective distress from pre- to post-exposure, but after the delay, significantly greater distress (attenuated extinction recall). Results suggest that women with lower estradiol may respond less favorably to exposure therapy for OCD relative to women with higher estradiol. These findings await replication in larger samples with longer recall delays. Should replication occur, these results may inform the use of estradiol to augment exposure therapy.

A Family Genetic Study of Obsessive Compulsive Disorder in Youth

Objective: To use a family genetic study to evaluate familial risk of obsessive compulsive disorder (OCD) and common comorbid illnesses in first-degree relatives of pediatric-onset probands with primary OCD. Method: One hundred and thirty youth with OCD and their 133 siblings and 241 parents and 49 pediatric controls were directly evaluated along multiple domains including psychopathology using structured diagnostic interviews and clinical corroboration. Results: Rates of anxiety, mood, disruptive behavior, and tic disorders were markedly elevated in the probands while rates in siblings were elevated at rates between the probands and controls. Twenty six percent of first-degree relatives had clinical OCD, 9% had chronic tics or Tourette’s disorder, and 21% met criteria for ADHD. Conclusion: Rates of familial transmission of OCD and common comorbid illnesses were significantly higher in our pediatric-onset probands than rates reported in the literature in relatives of those with adult-onset OCD.

Online Video Teletherapy Treatment of Obsessive-Compulsive Disorder Using Exposure and Response Prevention: Clinical Outcomes From a Retrospective Longitudinal Observational Study.

BackgroundExposure and response prevention, a type of cognitive-behavioral therapy, is an effective first-line treatment for obsessive-compulsive disorder (OCD). Despite extensive evidence of the efficacy of exposure and response prevention (ERP) from clinical studies and in real-world samples, it is still underused as a treatment. This is likely due to the limits to access to care that include the availability of adequately trained therapists, as well as geographical location, time, and cost barriers. To address these, NOCD created a digital behavioral health treatment for OCD using ERP delivered via video teletherapy and with technology-assisted elements including app-based therapy tools and between-session therapist messaging.ObjectiveWe examined treatment outcomes in a large naturalistic sample of 3552 adults with a primary OCD diagnosis who received NOCD treatment.MethodsThe treatment model consisted of twice-weekly, live, face-to-face video teletherapy ERP for 3 weeks, followed by 6 weeks of once-weekly brief video teletherapy check-ins for 30 minutes. Assessments were conducted at baseline, at midpoint after completion of 3 weeks of twice-weekly sessions, and at the end of 6 weeks of brief check-ins (endpoint). Longitudinal assessments were also obtained at 3, 6, 9, and 12 months after endpoint.ResultsTreatment resulted in clinically and statistically significant improvements, with a 43.4% mean reduction in obsessive-compulsive symptoms (g=1.0; 95% CI 0.93 to 1.03) and a 62.9% response rate. Treatment also resulted in a 44.2% mean reduction in depression, a 47.8% mean reduction in anxiety, and a 37.3% mean reduction in stress symptoms. Quality of life improved by a mean of 22.7%. Reduction in OCD symptoms and response rates were similar for those with mild, moderate, or severe symptoms. The mean duration of treatment was 11.5 (SD 4.0) weeks, and the mean total therapist time was 10.6 (SD 1.1) hours. Improvements were maintained at 3, 6, 9, and 12 months.ConclusionsIn this sample, representing the largest reported treated cohort of patients with OCD to date, video teletherapy treatment demonstrated effectiveness in reducing obsessive-compulsive and comorbid symptoms and improved quality of life. Further, it achieved meaningful results in less than half the total therapist time compared with standard once-weekly outpatient treatment, an efficiency that represents substantial monetary and time savings. The effect size was large and similar to studies of in-person ERP. This technology-assisted remote treatment is readily accessible for patients, offering an advancement in the field in the dissemination of effective evidence-based care for OCD.

Obsessive-Compulsive Disorder and quality of life outcomes: protocol for a systematic review and meta-analysis of cross-sectional case-control studies


 Background. Obsessive-compulsive Disorder (OCD) is a chronic disabling psychological condition, which can severely affect quality of life (QOL). Growing interest has been dedicated to assessing which domains of QOL are more severely affected in patients with OCD. However, research yielded conflicting findings. Investigating QOL in OCD could suggest the need for integration of interventions aimed at improving those specific domains more severely impaired by obsessions and compulsions.
 Methods. We will conduct a systematic review of cross-sectional case-control studies according to PRISMA guidelines, where patients with a primary OCD diagnosis were compared on QOL outcomes with healthy controls. Primary objectives will be to examine differences in QOL outcomes between patients with OCD and healthy controls, and to assess which QOL domains are more severely impaired in patients compared with controls, particularly subjective well-being, social and interpersonal functioning, work functioning, and family functioning. Subsequently, the study will investigate potential moderators of QOL in OCD, including participants characteristics (age, sex, presence of comorbid personality disorders, OCD symptom severity, severity of concurrent depressive symptoms, duration of OCD symptoms, and generational cohort), and study characteristics (date of publication and methodological quality of the studies). Online databases will be searched (PsycINFO, PubMED, Science Direct, Cinahl, Biological Abstracts, Psyclit, Embase, The Cochrane Central Register of Controlled Trials, and Google Scholar). To locate unpublished records, conference abstracts, doctoral dissertations and theses will be handsearched, and experts will be contacted. Statistical analyses will be performed though random effect model meta-analysis. Risk of bias assessments will be conducted using the instrument Methodological Index for Non-Randomized Studies.

Family-based cognitive behavioural therapy versus family-based relaxation therapy for obsessive-compulsive disorder in children and adolescents: protocol for a randomised clinical trial (the TECTO trial)

BackgroundCognitive behavioural therapy (CBT) is the recommended first-line treatment for children and adolescents with obsessive-compulsive disorder (OCD), but evidence concerning treatment-specific benefits and harms compared with other interventions is limited. Furthermore, high risk-of-bias in most trials prevent firm conclusions regarding the efficacy of CBT. We investigate the benefits and harms of family-based CBT (FCBT) versus family-based psychoeducation and relaxation training (FPRT) in youth with OCD in a trial designed to reduce risk-of-bias.MethodsThis is an investigator-initiated, independently funded, single-centre, parallel group superiority randomised clinical trial (RCT). Outcome assessors, data managers, statisticians, and conclusion drawers are blinded. From child and adolescent mental health services we include patients aged 8–17 years with a primary OCD diagnosis and an entry score of ≥16 on the Children’s Yale-Brown Obsessive-Compulsive Scale (CY-BOCS). We exclude patients with comorbid illness contraindicating trial participation; intelligence quotient < 70; or treatment with CBT, PRT, antidepressant or antipsychotic medication within the last 6 months prior to trial entry. Participants are randomised 1:1 to the experimental intervention (FCBT) versus the control intervention (FPRT) each consisting of 14 75-min sessions. All therapists deliver both interventions. Follow-up assessments occur in week 4, 8 and 16 (end-of-treatment). The primary outcome is OCD symptom severity assessed with CY-BOCS at end-of-trial. Secondary outcomes are quality-of-life and adverse events. Based on sample size estimation, a minimum of 128 participants (64 in each intervention group) are included.DiscussionIn our trial design we aim to reduce risk-of-bias, enhance generalisability, and broaden the outcome measures by: 1) conducting an investigator-initiated, independently funded RCT; 2) blinding investigators; 3) investigating a representative sample of OCD patients; 3) using an active control intervention (FPRT) to tease apart general and specific therapy effects; 4) using equal dosing of interventions and therapist supervision in both intervention groups; 5) having therapists perform both interventions decided by randomisation; 6) rating fidelity of both interventions; 7) assessing a broad range of benefits and harms with repeated measures.The primary study limitations are the risk of missing data and the inability to blind participants and therapists to the intervention.Trial registrationClinicalTrials.gov: NCT03595098, registered July 23, 2018.

The OCI-CV-R: A Revision of the Obsessive-Compulsive Inventory - Child Version.

The Obsessive-Compulsive Inventory-Children's Version (OCI-CV) was developed to assess obsessive-compulsive symptoms in youth. Recent changes in the Diagnostic and Statistical Manual (DSM-5) exclude hoarding from inclusion in the diagnosis of obsessive-compulsive disorder (OCD). Accordingly, the present study examined the reliability, validity, factorial structure, and diagnostic sensitivity of a revised version of the scale - the OCI-CV-R- that excludes items assessing hoarding. Participant were 1047 youth, including 489 meeting DSM criteria for primary OCD, 298 clinical controls, and 260 nonclinical controls, who completed the OCI-CV and measures of obsessive-compulsive symptom severity, depression, and anxiety at various treatment and research centers. Findings support a five-factor structure (doubting/checking, obsessing, washing, ordering, and neutralizing), with a higher order factor. Factorial invariance was found for older (12-17 years) and younger (7-11 years) children. Internal consistency of the OCI-CV-R was acceptable, and discriminant and convergent validity were adequate and akin to that of its progenitor. Diagnostic sensitivity and specificity were found for a total score of 8 and higher. It is recommended that the OCI-CV-R replace the former version, and that this measure serve as part of a comprehensive clinical assessment of youth with OCD. Recommendations for further research with ethnically and racially diverse samples, as well as the need to establish benchmark scores are discussed.

OCD in the time of COVID-19: A global pandemic's impact on mental health patients and their treatment providers.

Individuals with obsessive-compulsive disorder (OCD) have evidenced resilience against large-scale crises, although emerging research on the impact of COVID-19 is mixed. Little is known about the impact of COVID-19 on mental health providers. Items from an instrument evaluating the impact of the September 11, 2001, terrorist attack were adapted to measure the impact of COVID-19 on emotions, cognitions, and behaviors. Using a sample of 65 patients with primary OCD diagnoses and OCD treatment providers in intensive programs for OCD and anxiety, the authors found that COVID-19 evidenced a less significant overall impact on patients than providers. Specifically, providers reported more significant impact on the amount of time spent worrying about COVID-19, taking additional cleaning and sanitization precautions, and time spent socializing with loved ones. Findings support previous literature indicating that individuals with OCD demonstrate resilience to large-scale crises, and offer insights into the specific struggles of providers who treat OCD.

Dysfunctional Brain Reward System in Child Obesity.

Eating habits leading to obesity may reflect nonhomeostatic behavior based on excessive immediate-reward seeking. However, it is currently unknown to what extent excess weight is associated with functional alterations in the brain's reward system in children. We tested the integrity of reward circuits using resting-state functional connectivity magnetic resonance imaging in a population of 230 children aged 8-12years. The major components of the reward system were identified within the ventral striatum network defined on the basis of the nucleus accumbens connectivity pattern. The functional structure of the cerebral cortex was characterized using a combination of local functional connectivity measures. Higher body mass index was associated with weaker connectivity between the cortical and subcortical elements of the reward system, and enhanced the integration of the sensorimotor cortex to superior parietal areas relevant to body image formation. Obese children, unlike WHO-defined overweight condition, showed functional structure alterations in the orbitofrontal cortex and amygdala region similar to those previously observed in primary obsessive-compulsive disorder and Prader-Willi syndrome associated with obsessive eating behavior. Results further support the view that childhood obesity is not simply a deviant habit with restricted physical health consequences but is associated with reward system dysfunction characterizing behavioral control disorders.

Serotonin transporter gene promoter hypomethylation in obsessive-compulsive disorder – Predictor of impaired response to exposure treatment?

Treatment resistance is common in obsessive-compulsive disorder (OCD) and associated with a significant burden for the individual patient. Accordingly, the identification of biomarkers as early predictors of the clinical response has become a central goal in the search for more efficacious and personalized treatments. Epigenetic mechanisms such as DNA methylation of the serotonin transporter gene (SLC6A4) have been suggested to predict therapy outcome in mental disorders closely related to OCD, but have not yet been investigated as such in OCD. The present therapy-epigenetic study therefore sought to address the potential role of SLC6A4 promoter methylation in the prediction of treatment response for the first time in OCD.Overall, 112 patients with primary OCD were investigated over the course of 8–10-week OCD-specific, cognitive behavioral therapy (CBT) comprising exposure and response prevention/management (phase I) and in vivo exposure exercises (‘flooding’, phase II). OCD symptoms were measured using the Yale-Brown Obsessive Compulsive Scale (Y-BOCS) at baseline as well as before and after the in vivo exposure phase. SLC6A4 promoter methylation at baseline was analyzed via pyrosequencing of sodium bisulfite-treated DNA extracted from blood cells.Lower baseline SLC6A4 promoter methylation predicted impaired treatment response (defined as reduction in Y-BOCS scores) in phase II (but not phase I) of CBT (β = −0.359, p = .002).SLC6A4 methylation may thus constitute a potential early biomarker predicting biologically mediated clinical changes elicited specifically by exposure treatment. These results carry promise for clinical application and in the future could aid in early treatment modification and personalized treatment efforts.

Bidirectional comorbidity between bipolarand obsessive-compulsive disorders: symptoms frequency, treatment challenges and underexplored areas

The high comorbidity of bipolar- (BD) and obsessive-compulsive disorder (OCD) is a challenge in the psychiatric field. This topic has been scarcely investigated in Latin America, and we could not find published studies conducted in Venezuela. Given the common difficulty to establish a categorical diagnosis in comorbid conditions, we assessed the frequency of current OC symptoms (OCS) in subjects with primary BD, and of BD symptoms (BDS) insubjects with primary OCD. We administered the Yale-Brown Obsessive-CompulsiveScale (Y-BOCS) to 40 patients with BD, and the Young Mania RatingScale (YMRS) and the Mood Disorder Questionnaire (MDQ) to 42 patients withOCD. We observed clinically significant OCS (Y-BOCS score ≥ 16) in 20% of BDsubjects, and current hypomania or mania in 16.7% and 19% of OCD patientsrespectively. A significant positive correlation between age and YMRS was detectedin OCD females, p = 0.04. We here confirmed the high comorbidity inthe bipolar and obsessive-compulsive dimensions. Numerous studies identifythe clinical burden, diagnostic difficulties and treatment intricacy of this comorbidity,which warrants for further research to assist this sensible population.We illustrate the challenges of pharmacological and psychological treatment,and the issue of family history of psychopathology, with two conspicuousclinical vignettes extracted from the studied sample.

Efficacy and clinical predictors of response to rTMS treatment in pharmacoresistant obsessive-compulsive disorder (OCD): a retrospective study

BackgroundApplication of repetitive transcranial magnetic stimulation (rTMS) for treating obsessive-compulsive disorder (OCD) has been promising and approved by the Food and Drug Administration in 2018, but effects differ between patients. Knowledge about clinical predictors of rTMS response may help to increase clinical efficacy but is not available so far.MethodsIn a retrospective study, we investigated the efficacy of rTMS over the dorsolateral prefrontal cortex (DLPFC) or supplementary motor area (SMA) in 65 pharmaco-resistant OCD outpatients recruited for rTMS treatment from July 2015 to May 2017. Patients received either SMA rTMS (n = 38) or bilateral DLPFC rTMS (n = 27) in case of reporting higher affective and depressive symptoms in addition to the primary OCD symptoms. OCD symptoms and depression/anxiety states were measured at baseline (before the 1st session) and after the 20th session of rTMS. Additionally, we performed a binary logistic regression analysis on the demographic and clinical variables based on the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) 3-factor and 2-factor models and individual items to investigate potential predictors of rTMS response.ResultsPatients’ scores in Y-BOCS and Beck anxiety/depression inventories were significantly decreased following rTMS treatment. 46.2% of all patients responded to rTMS, based on the criterion of at least a 30% reduction in Y-BOCS scores. There was no significant difference between response rates of patients in DLPFC and SMA groups. No significant demographic predictors of rTMS efficacy were identified. The factors “obsession severity”, “resistance” and “disturbance” and the “interference due to obsessions” and “resistance against compulsions” items of the Y-BOCS significantly predicted response to rTMS.ConclusionsIn patients with less intrusive/interfering thoughts, and low scores in the “obsession severity”, “disturbance”, and “resistance” factors, rTMS might have superior effects. Identifying clinical and non-clinical predictors of response is relevant to personalize and adapt rTMS protocols in pharmaco-resistant OCD patients. Interpretation of rTMS efficacy should be done with caution due to the lack of a sham intervention condition.

Monoamine Oxidase A Hypomethylation in Obsessive-Compulsive Disorder: Reversibility By Successful Psychotherapy?

BackgroundEpigenetic markers such as DNA methylation of the monoamine oxidase A (MAOA) gene have previously been shown to be altered in anxiety- and stress-related disorders and to constitute a potential mechanism of action of psychotherapeutic interventions such as cognitive behavioral therapy in these disorders. The present study for the first time, to our knowledge, investigated MAOA methylation in patients with obsessive-compulsive disorder applying a longitudinal psychotherapy-epigenetic approach.MethodsThe present sample comprised 14 unmedicated female patients with primary obsessive-compulsive disorder and 14 age- and sex-matched healthy controls. MAOA promoter methylation was analyzed via direct sequencing of sodium bisulfite-treated DNA extracted from whole blood before and after an 8- to 10-week semi-standardized, obsessive-compulsive disorder–specific cognitive behavioral therapy. Clinical response was assessed by means of the Yale-Brown Obsessive Compulsive Scale.ResultsSignificantly lower MAOA promoter methylation was discerned in obsessive-compulsive disorder patients relative to healthy controls. Data were available for 12 patients with obsessive-compulsive disorder and 14 controls. Furthermore, following cognitive behavioral therapy, clinical improvement, i.e., decreases in obsessive-compulsive disorder symptoms as indicated by lower scores on the Yale-Brown Obsessive Compulsive Scale was found to be significantly correlated with increases in MAOA methylation levels in patients (data available for n = 7).ConclusionsThe present pilot data suggest MAOA hypomethylation as a potential risk marker of obsessive-compulsive disorder and an increase in MAOA methylation levels as a possible mechanistic correlate of response to cognitive behavioral therapy in obsessive-compulsive disorder.

Effects and side effects of a transdiagnostic bias modification intervention in a mixed sample with obsessive-compulsive and/or depressive symptoms-a randomized controlled trial.

Obsessive-compulsive disorder (OCD) and major depression disorder (MDD) are underdiagnosed and undertreated mental disorders. Prior studies have verified the efficacy of the self-help manual My Metacognitive Training (myMCT) for patients with primary OCD. As depression and OCD share a number of (meta)cognitive biases and dysfunctional coping strategies, we examined the efficacy of myMCT in a mixed patient sample with OCD and/or depression. A total of 80 Italian-speaking individuals with symptoms of OCD and/or depression were randomized to either myMCT or to a waitlist control group (both groups had access to care as usual during the intervention). Post-assessment was carried out 6 weeks after inclusion. Scores on the Beck Depression Inventory-II scale (BDI-II) served as the primary outcome. Adverse effects were assessed with a newly devised self-report scale. Participants in the myMCT condition showed significant symptom improvement on the BDI-II scale at a medium to large effect size compared to the control group (using intention-to-treat and per protocol analyses). The intention-to-treat analyses yielded significant positive effects on the PHQ-9 scores and psychological as well as environmental well-being in favor of myMCT; for the OCI-R total score, group differences bordered significance in favor of the myMCT. The most prevalent adverse effects were feeling pressured by the suggested exercises or feeling bad due to not performing the exercises correctly. Our results indicate that the myMCT manual represents an effective program for patients with OCD as well as those with depressive symptoms in an Italian-speaking population. Adverse events due to unguided self-help deserve more attention in the future.

Lifetime bipolar disorder comorbidity and related clinical characteristics in patients with primary obsessive compulsive disorder: a report from the International College of Obsessive-Compulsive Spectrum Disorders (ICOCS).

Bipolar disorder (BD) and obsessive compulsive disorder (OCD) are prevalent, comorbid, and disabling conditions, often characterized by early onset and chronic course. When comorbid, OCD and BD can determine a more pernicious course of illness, posing therapeutic challenges for clinicians. Available reports on prevalence and clinical characteristics of comorbidity between BD and OCD showed mixed results, likely depending on the primary diagnosis of analyzed samples. We assessed prevalence and clinical characteristics of BD comorbidity in a large international sample of patients with primary OCD (n = 401), through the International College of Obsessive-Compulsive Spectrum Disorders (ICOCS) snapshot database, by comparing OCD subjects with vs without BD comorbidity. Among primary OCD patients, 6.2% showed comorbidity with BD. OCD patients with vs without BD comorbidity more frequently had a previous hospitalization (p < 0.001) and current augmentation therapies (p < 0.001). They also showed greater severity of OCD (p < 0.001), as measured by the Yale-Brown Obsessive Compulsive Scale (Y-BOCS). These findings from a large international sample indicate that approximately 1 out of 16 patients with primary OCD may additionally have BD comorbidity along with other specific clinical characteristics, including more frequent previous hospitalizations, more complex therapeutic regimens, and a greater severity of OCD. Prospective international studies are needed to confirm our findings.

Empirically-derived response trajectories of intensive residential treatment in obsessive-compulsive disorder: A growth mixture modeling approach

BackgroundThis study investigated distinct trajectories of treatment response in a naturalistic intensive/residential treatment (IRT) program for adults with severe obsessive-compulsive disorder (OCD). We hypothesized that: (1) distinct trajectories would emerge and (2) demographic variables, psychiatric comorbidity, OCD symptom subtype, level of insight, previous exposure and response prevention (ERP) treatment, and quality of life, would differentially predict assignment to these trajectories. MethodsParticipants included 305 individuals with primary OCD admitted for IRT. ResultsTwo trajectories emerged over the course of the first eight weeks of treatment, with the vast majority of participants demonstrating treatment response. The first trajectory (96%, n = 292) showed a negative, linear treatment response (a.k.a. “linear responders”) and more severe OCD symptoms at admission. The second trajectory (4%, n = 13) had less severe OCD symptoms at admission and did not exhibit a significant overall change in symptoms over the course of treatment. More specifically, this second trajectory or “u-shaped responders” show a non-significant linear response through week four of treatment, followed by slightly increased symptoms in week five. Assignment to these classes was not differentially predicted by hypothesized predictor variables. LimitationsOur final model had inconsistent fit indices and small class prevalance of the u-shaped responder group; therefore, model selection was based on both fit indices and substantive meaning. ConclusionsThis study emprically derived two distinct trajectories of OCD symptom severity over the course of IRT. These findings have the potential to refine IRT for patients with severe OCD, and to potentially guide future investigation into the optimal delivery of ERP treatment for OCD generally.

Quality of Life in Children and Youth with Obsessive-Compulsive Disorder.

The study examined clinical correlates of quality of life (QoL), impact of treatment on QoL, and predictors of QoL change among children with obsessive-compulsive disorder (OCD). One hundred forty-two children with primary OCD who were enrolled as part of a larger clinical trial participated. Children were administered a structured diagnostic interview, as well as clinician-administered measures of OCD and depression symptom severity. Children and parents completed reports of QoL, as well as measures of impairment and internalizing and externalizing symptoms. Youth received 10 sessions of family-based cognitive-behavioral therapy (CBT). At baseline, QoL was inversely related to obsessive-compulsive symptom severity, impairment, externalizing and internalizing symptoms, and severity of depression symptoms according to children and parents. After CBT, QoL improved according to parent ratings, but not child ratings. None of the predictors examined were associated with changes in QoL scores over time. Impairment, and externalizing and internalizing symptoms predicted QoL after accounting for OCD symptom severity. After accounting for OCD symptoms, externalizing symptoms inversely predicted changes in QoL. These data suggest that QoL is related to more severe clinical presentation and improves with evidence-based treatment, but QoL improvements may be inversely related to externalizing symptomology.

Low-intensity cognitive-behaviour therapy interventions for obsessive-compulsive disorder compared to waiting list for therapist-led cognitive-behaviour therapy: 3-arm randomised controlled trial of clinical effectiveness.

BackgroundObsessive-compulsive disorder (OCD) is prevalent and without adequate treatment usually follows a chronic course. “High-intensity” cognitive-behaviour therapy (CBT) from a specialist therapist is current “best practice.” However, access is difficult because of limited numbers of therapists and because of the disabling effects of OCD symptoms. There is a potential role for “low-intensity” interventions as part of a stepped care model. Low-intensity interventions (written or web-based materials with limited therapist support) can be provided remotely, which has the potential to increase access. However, current evidence concerning low-intensity interventions is insufficient. We aimed to determine the clinical effectiveness of 2 forms of low-intensity CBT prior to high-intensity CBT, in adults meeting the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) criteria for OCD.Methods and findingsThis study was approved by the National Research Ethics Service Committee North West–Lancaster (reference number 11/NW/0276). All participants provided informed consent to take part in the trial. We conducted a 3-arm, multicentre randomised controlled trial in primary- and secondary-care United Kingdom mental health services. All patients were on a waiting list for therapist-led CBT (treatment as usual). Four hundred and seventy-three eligible patients were recruited and randomised. Patients had a median age of 33 years, and 60% were female. The majority were experiencing severe OCD. Patients received 1 of 2 low-intensity interventions: computerised CBT (cCBT; web-based CBT materials and limited telephone support) through “OCFighter” or guided self-help (written CBT materials with limited telephone or face-to-face support). Primary comparisons concerned OCD symptoms, measured using the Yale-Brown Obsessive Compulsive Scale–Observer-Rated (Y-BOCS-OR) at 3, 6, and 12 months. Secondary outcomes included health-related quality of life, depression, anxiety, and functioning. At 3 months, guided self-help demonstrated modest benefits over the waiting list in reducing OCD symptoms (adjusted mean difference = −1.91, 95% CI −3.27 to −0.55). These effects did not reach a prespecified level of “clinically significant benefit.” cCBT did not demonstrate significant benefit (adjusted mean difference = −0.71, 95% CI −2.12 to 0.70). At 12 months, neither guided self-help nor cCBT led to differences in OCD symptoms. Early access to low-intensity interventions led to significant reductions in uptake of high-intensity CBT over 12 months; 86% of the patients allocated to the waiting list for high-intensity CBT started treatment by the end of the trial, compared to 62% in supported cCBT and 57% in guided self-help. These reductions did not compromise longer-term patient outcomes. Data suggested small differences in satisfaction at 3 months, with patients more satisfied with guided self-help than supported cCBT. A significant issue in the interpretation of the results concerns the level of access to high-intensity CBT before the primary outcome assessment.ConclusionsWe have demonstrated that providing low-intensity interventions does not lead to clinically significant benefits but may reduce uptake of therapist-led CBT.Trial registrationInternational Standard Randomized Controlled Trial Number (ISRCTN) Registry ISRCTN73535163.

Comorbidity, age of onset and suicidality in obsessive–compulsive disorder (OCD): An international collaboration

ObjectivesTo collate data from multiple obsessive–compulsive disorder (OCD) treatment centers across seven countries and five continents, and to report findings in relation to OCD comorbidity, age of onset of OCD and comorbid disorders, and suicidality, in a large clinical and ethnically diverse sample, with the aim of investigating cultural variation and the utility of the psychiatric diagnostic classification of obsessive–compulsive and related disorders. MethodsResearchers in the field of OCD were invited to contribute summary statistics on current and lifetime psychiatric comorbidity, age of onset of OCD and comorbid disorders and suicidality in their patients with OCD. ResultsData from 3711 adult patients with primary OCD came from Brazil (n=955), India (n=802), Italy (n=750), South Africa (n=565), Japan (n=322), Australia (n=219), and Spain (n=98). The most common current comorbid disorders were major depressive disorder (28.4%; n=1055), obsessive–compulsive personality disorder (24.5%, n=478), generalized anxiety disorder (19.3%, n=716), specific phobia (19.2%, n=714) and social phobia (18.5%, n=686). Major depression was also the most commonly co-occurring lifetime diagnosis, with a rate of 50.5% (n=1874). OCD generally had an age of onset in late adolescence (mean=17.9years, SD=1.9). Social phobia, specific phobia and body dysmorphic disorder also had an early age of onset. Co-occurring major depressive disorder, generalized anxiety disorder and psychotic disorders tended to have a later age of onset than OCD. Suicidal ideation within the last month was reported by 6.4% (n=200) of patients with OCD and 9.0% (n=314) reported a lifetime history of suicide attempt. ConclusionsIn this large cross-continental study, comorbidity in OCD was common. The high rates of comorbid major depression and anxiety disorders emphasize the need for clinicians to assess and monitor for these disorders. Earlier ages of onset of OCD, specific phobia and social phobia may indicate some relatedness between these disorders, but this requires further study. Although there do not appear to be significant cultural variations in rates or patterns of comorbidity and suicidality, further research using similar recruitment strategies and controlling for demographic and clinical variables may help to determine whether any sociocultural factors protect against suicidal ideation or psychiatric comorbidity in patients with OCD.

Quality of life in children and adolescents with obsessive-compulsive disorder: a systematic review and meta-analysis.

Obsessive–compulsive disorder (OCD) is a seriously impairing psychiatric condition that affects 1%–3% of youth. Investigating the quality of life (QOL) is an important issue for treatment planning of this disorder, as targeting symptoms without taking it into account may bias assessment and prognosis when the patient presents with reduced symptoms that do not correspond to improved QOL. However, QOL in young individuals with OCD has been understudied. This meta-analysis summarized current evidence that assessed differences in global, social and school QOL dimensions, between children/adolescents with OCD and screened controls. Age, sex and OCD severity were examined as moderators. Case–control studies were included if children/adolescents with primary OCD were compared with screened controls on validated self-reported QOL outcomes. Online databases (January 1966–January 2016) were searched. Five case–control studies were included (n=543, 17 effect sizes overall). On global QOL, a large effect size emerged (d=−1.16, P<0.001), suggesting that individuals with OCD had lower global QOL than controls. Moderate effect sizes emerged for school (d=−0.61, P<0.01) and social QOL (d=−0.54, P<0.01), respectively, indicating worse QOL on these domains for individuals with OCD. For samples with higher OCD severity, global QOL of individuals with OCD was lower than that for controls (β=−0.02, P<0.05). For samples with lower percentages of females, global QOL of individuals with OCD was more impaired (β=0.02, P<0.001). Age was not correlated with effect sizes. Assessment and treatment should target QOL for young males suffering from more severe OCD. The small number of included studies highlighted that QOL is under-recognized. Future research should focus on additional QOL domains and compare which ones are impaired among individuals with OCD compared with other psychiatric conditions. Overall, the results pointed out the importance of addressing QOL in both practice and research on assessment and treatment of children/adolescents with this condition.
