Exposure And Ritual Prevention Research Articles

The effectiveness and acceptability of the Bergen 4-day treatment for adolescents with OCD: a replication and extension.

B4DT is a concentrated treatment format with prolonged sessions of exposure and ritual prevention (ERP) delivered over four consecutive days. Two previous open trials demonstrated promising results of the Bergen 4-day treatment (B4DT) for adolescents with obsessive-compulsive disorder (OCD). The aim of the current study was to replicate the initial results with a new sample of adolescents and different therapists at different sites across Norway. Forty-three youths participated in treatment program. At pretreatment, posttreatment, and the three-month follow-up, OCD symptoms were assessed using the CY-BOCS interview, while the GAD-7 and PHQ-9 were administered to rate general anxiety symptoms and depressive symptoms. Acceptability and patient satisfaction with the treatment were rated with the CSQ-8. All symptoms were significantly reduced at posttreatment and follow-up. At posttreatment, 36 patients (85.71%) were defined as responders, while 29 patients (69.05%) achieved remission. At the three-month follow-up, 36 patients (92.3%) were defined as responders, while 33 patients (84.62%) were in remission. CSQ-8 scores indicated that the patients were highly satisfied with the treatment. The B4DT was successfully replicated in a new sample at different sites across Norway, which indicates that this treatment is generalizable, effective and acceptable to adolescents with OCD.

Best practices for CBT treatment of taboo and unacceptable thoughts in OCD

AbstractAlthough general cognitive behavioural therapy (CBT) can help alleviate distress associated with obsessive-compulsive disorder (OCD), strategies tailored to targeting specific cognitions, feelings, and behaviours associated with OCD such as exposure and ritual prevention (Ex/RP) and cognitive therapy (CT) have been shown to be a significantly more effective form of treatment. Treatment of individuals with unacceptable/taboo obsessions requires its own specific guidelines due to the stigmatizing and often misunderstood nature of accompanying thoughts and behaviours. In this article, OCD expert practitioners describe best practices surrounding two of the longest standing evidence-based treatment paradigms for OCD, CT and Ex/RP, tailored specifically to unacceptable and taboo obsessions, so that clients may experience the best possible outcomes that are sustained once treatment ends. In addition, CT specifically targets obsessions while Ex/RP addresses compulsions, allowing the two to be highly effective when combined together. A wide range of clinical recommendations on clinical competencies is offered, including essential knowledge, psychoeducation, designing fear hierarchies and exposures, instructing the client through behavioural experiments, and relapse prevention skills.Key learning aims(1)To learn about the theoretical underpinnings of specialized approaches to treating taboo/unacceptable thoughts subtype of OCD with gold-standard CBT treatments, cognitive therapy (CT) and exposure and ritual prevention (Ex/RP).(2)To learn about recognizing and identifying commonly missed covert cognitive symptoms in OCD such as rumination and mental compulsions.(3)To learn how to assess commonly unrecognized behavioural symptoms in OCD such as concealment, reassurance seeking, searching on online forums, etc.(4)To gain a nuanced understanding of the phenomenology of the taboo/unacceptable thoughts OCD subtype and the cycles that maintain symptoms and impairment.(5)To learn about in-session techniques such as thought experiments, worksheets, fear hierarchies, and different types of exposures.

Maximizing remission from cognitive-behavioral therapy in medicated adults with obsessive-compulsive disorder

Practice guidelines for adults with obsessive-compulsive disorder (OCD) recommend augmenting serotonin reuptake inhibitors (SRIs) with exposure and ritual prevention (EX/RP). However, fewer than half of patients remit after a standard 17-session EX/RP course. We studied whether extending the course increased overall remission rates and which patient factors predicted remission. Participants were 137 adults with clinically significant OCD (Yale-Brown Obsessive Compulsive Scale [Y-BOCS] score ≥18) despite an adequate SRI trial (≥12 weeks). Continuing their SRI, patients received 17 sessions of twice-weekly EX/RP (standard course). Patients who did not remit (Y-BOCS ≤12) received up to 8 additional sessions (extended course). Of 137 entrants, 123 completed treatment: 49 (35.8%) remitted with the standard course and another 46 (33.6%) with the extended course. Poorer patient homework adherence, more Obsessive-Compulsive Personality Disorder (OCPD) traits, and the Brain-Derived Neurotrophic Factor (BDNF) Val66MET genotype were associated with lower odds of standard course remission. Only homework adherence differentiated non-remitters from extended course remitters. Extending the EX/RP course from 17 to 25 sessions enabled many (69.3%) OCD patients on SRIs to achieve remission. Although behavioral (patient homework adherence), psychological (OCPD traits), and biological (BDNF genotype) factors influenced odds of EX/RP remission, homework adherence was the most potent patient factor overall.

Delayed Sleep Timing in Obsessive-Compulsive Disorder Is Associated With Diminished Response to Exposure and Ritual Prevention

Exposure and ritual prevention (ERP) and pharmacotherapy are typically associated with significant symptom reductions for individuals with obsessive-compulsive disorder (OCD). However, many patients are left with residual symptoms and other patients do not respond. There is increasing evidence that delays in sleep timing/circadian rhythms are associated with OCD but the potential effects of delays in sleep timing on ERP warrant attention. This paper presents data from 31 outpatients with OCD who participated in ERP. Results showed that delayed sleep timing was common and that individuals with delayed bedtimes benefited significantly less from treatment and were significantly more likely to be nonresponders compared to individuals with earlier bedtimes. Further, the effects of sleep timing remained statistically significant even after controlling for global sleep quality, negative affect, and several other variables. These findings add to a growing literature suggesting the utility of better understanding the role of disruptions in the timing of sleep in OCD.

Network-based functional connectivity predicts response to exposure therapy in unmedicated adults with obsessive-compulsive disorder.

Obsessive-compulsive disorder (OCD) is associated with alterations in cortico-striato-thalamo-cortical brain networks, but some resting-state functional magnetic resonance imaging studies report more diffuse alterations in brain connectivity. Few studies have assessed functional connectivity within or between networks across the whole brain in unmedicated OCD patients or how patterns of connectivity predict response to exposure and ritual prevention (EX/RP) therapy, a first-line treatment for OCD. Herein, multiband resting-state functional MRI scans were collected from unmedicated, adult patients with OCD (n = 41) and healthy participants (n = 36); OCD patients were then offered twice weekly EX/RP (17 sessions). A whole-brain-network-based statistic approach was used to identify group differences in resting-state connectivity. We detected altered pre-treatment functional connectivity between task-positive regions in the temporal gyri (middle and superior) and regions of the cingulo-opercular and default networks in individuals with OCD. Signal extraction was performed using a reconstruction independent components analysis and isolated two independent subcomponents (IC1 and IC2) within this altered connectivity. In the OCD group, linear mixed-effects models tested whether IC1 or IC2 values predicted the slope of change in Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) scores across EX/RP treatment. Lower (more different from controls) IC2 score significantly predicted greater symptom reduction with EX/RP (Bonferroni-corrected p = 0.002). Collectively, these findings suggest that an altered balance between task-positive and task-negative regions centered around temporal gyri may contribute to difficulty controlling intrusive thoughts or urges to perform ritualistic behaviors.

Task-based fMRI predicts response and remission to exposure therapy in obsessive-compulsive disorder

Exposure and ritual prevention (EX/RP) is an effective first-line treatment for obsessive-compulsive disorder (OCD), but only some patients achieve minimal symptoms following EX/RP. Herein, we investigate whether task-based neural activity can predict who responds best to EX/RP. Unmedicated adult patients with OCD (n = 36) and healthy participants (n = 33) completed the Simon Spatial Incompatibility Task during high-resolution, multiband functional MRI (fMRI); patients were then offered twice-weekly EX/RP (17 sessions). Linear mixed-effects models were used to identify brain regions where conflict-related activity moderated the slope of change in Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) scores across treatment. Conflict-related activity in the left pallidum and 35 cortical parcels/regions significantly predicted symptom improvement with EX/RP for patients with OCD (false discovery rate-corrected P < 0.05). Significant parcels/regions included cingulo-opercular and default mode network regions, specifically the anterior insula and anterior and posterior cingulate. Summarizing across these parcels/regions, greater conflict-related activity predicted greater EX/RP response and which patients achieved remission (Y-BOCS score ≤ 12; Cohen's d = 1.68) with >80% sensitivity and specificity. The association between brain activity and treatment response was partially mediated by patient EX/RP adherence (b = -2.99; 43.61% of total effect; P = 0.02). Brain activity and adherence together were highly predictive of remission. Together, these findings suggest that cingulo-opercular and default mode regions typically implicated in task control and introspective processes, respectively, may be targets for novel treatments that augment the ability of persons with OCD to resolve cognitive conflict and thereby facilitate adherence to EX/RP, increasing the likelihood of remission.

Introduction to the Special Issue: Challenges in Treating Obsessive-Compulsive Disorder With Cognitive-Behavioral Therapy.

Cognitive-behavioral therapy (CBT) is a recommended treatment for obsessive-compulsive disorder (OCD). CBT offers specific interventions with demonstrated efficacy, including both cognitive therapy and exposure and ritual prevention (ERP). Yet, implementing these techniques with individual patients can present clinical challenges. In this special issue, expert clinicians and researchers present cases in which they addressed some common challenges in implementing CBT for OCD, including comorbid depression, poor insight, and family accommodation of symptoms in pediatric OCD. Other papers present how CBT can be tailored to specific OCD manifestations, including post-partum OCD, taboo thoughts, and relationship OCD. Other authors detail how they have augmented standard ERP with additional treatment techniques to maximize outcomes. These articles present a diverse set of case histories and specific treatment techniques that illustrate ways to maximize the effectiveness of CBT for OCD, serving as a useful guide for clinicians in practice and highlighting areas for future research.

Behavioral therapy teams for adults with OCD in a community mental health center: An open trial

ObjectiveThis study assessed the acceptability and feasibility of a team-based approach to deliver Exposure and Ritual Prevention (ERP) for Obsessive Compulsive Disorder (OCD) in a community mental health center (CMHC). MethodGroup ERP was adapted to meet the needs of adults with OCD receiving treatment in a CMHC and to be delivered by behavioral therapy teams (BTT). A training program, treatment manual, and fidelity ratings were developed to train CMHC therapists and case managers. Participants received 12 group ERP sessions and 10 individual home-based coaching sessions over 12 weeks. ResultsEight participants entered group ERP. Feasibility and acceptability of the BTT intervention were good with six clients completing treatment, 89% of scheduled sessions attended, and high treatment satisfaction ratings. Fidelity ratings indicated staff adhered well to an ERP protocol. Half of treatment completers experienced clinically significant reductions in symptoms on the Yale-Brown Obsessive Compulsive Scale by post-treatment or at the 3-month follow-up. ConclusionsBTT appear to be a feasible and acceptable way to deliver ERP for OCD in CMHCs. Modifications to ERP for CMCH populations may be needed to increase the reach of the intervention.

Augmenting serotonin reuptake inhibitors in obsessive-compulsive disorder: What moderates improvement?

Patients with obsessive-compulsive disorder (OCD) often only partially respond to serotonin reuptake inhibitors (SRIs). In such cases, American Psychiatric Association practice guidelines suggest augmenting SRIs with cognitive-behavioral therapy consisting of exposure and ritual prevention (EX/RP) or antipsychotic medication (i.e., risperidone). We examined moderators and predictors of these 2 augmentation strategies. Data came from a randomized controlled trial that compared adding EX/RP or risperidone to SRIs in adults with OCD. Patients entered the study on a stable SRI dosage and were randomized to EX/RP (N = 40), risperidone (N = 40), or placebo (N = 20). Data were analyzed using multilevel modeling. Pretreatment OCD severity, age, and depression were significant moderators. Although OCD severity was unrelated to EX/RP response, individuals with more severe OCD had poorer outcomes and slower improvement with risperidone. Increasing age predicted better response to risperidone, but not EX/RP. Increased depression predicted poorer response to placebo, but not EX/RP or risperidone. Poorer functioning predicted worse outcome across all 3 conditions. Together, these moderators and predictor accounted for 33% of the variance in outcomes, above and beyond the 30.8% accounted for by treatment condition. SRI augmentation with EX/RP was more effective than risperidone across all of the demographic and clinical variables tested. EX/RP's superiority over risperidone increased with baseline OCD severity and with younger age. These data indicate that EX/RP should be the recommended SRI augmentation strategy, even for severe OCD. What determines the degree of EX/RP response in individual patients deserves further study.

EFFECTS OF HOMEWORK COMPLIANCE ON COGNITIVE-BEHAVIORAL THERAPY WITH D-CYCLOSERINE AUGMENTATION FOR CHILDREN WITH OBSESSIVE COMPULSIVE DISORDER.

The present study examined the effects of homework compliance on outcome from cognitive behavioral therapy (CBT) for children with obsessive-compulsive disorder (OCD) and the extent to which these effects differ as a function of augmentation of CBT with D-cycloserine (DCS). Twenty-seven youth with OCD were randomized to either 50 mg DCS or placebo (PBO) administered immediately after each of 10 CBT sessions, primarily consisting of exposure and ritual prevention (ERP). Independent evaluators assessed OCD severity using the Children's Yale-Brown Obsessive-Compulsive Scale (CY-BOCS) at the start of each session. Compliance with between-session ERP assignments was also assessed at the start of each session using the Patient ERP Adherence Scale (PEAS). Greater homework compliance between the previous session and the current session was related to lower CY-BOCS at the current session. However, the relation between homework compliance and CY-BOCS varied by treatment condition. Higher homework compliance was related to lower CY-BOCS for participants in the DCS condition, but not for participants in the PBO condition. Furthermore, participants receiving DCS were estimated to have significantly lower CY-BOCS than those given PBO among those with the highest levels of homework compliance. DCS may more effectively facilitate the effects of CBT for youth with OCD when patients are compliant with prescribed homework. Theoretical and clinical implications are discussed.

A Randomized Clinical Trial of a Brief Family Intervention to Reduce Accommodation in Obsessive-Compulsive Disorder: A Preliminary Study

Accommodation consists of changes in family members’ behavior to prevent or reduce patients’ obsessive–compulsive disorder (OCD) rituals or distress. High levels of family accommodation are associated with more severe symptoms and functional impairment in patients, and may also interfere with exposure-based treatment. The purpose of this study was to develop and test an intervention to reduce accommodation in the family members of adult OCD patients. Patients (N=18, mean age=35.44, 33% male, 94% Caucasian) received a course of standard individual exposure and ritual prevention (ERP) for OCD. Family members (N=18, mean age=41.72, 56% male, 94% Caucasian) were randomized to either receive or not receive the adjunctive intervention, consisting of two sessions of psychoeducation and skills training in reducing accommodation. Results revealed that the intervention successfully reduced scores on the clinician-rated Family Accommodation Scale (Week 8: d=1.05). Patients whose family members received the intervention showed greater reductions in Yale-Brown Obsessive–Compulsive Scale scores across treatment than patients whose family members had not (Week 8: d=1.27), and hierarchical regression analyses revealed that change in family accommodation from baseline accounted for a significant amount of variance in later OCD symptoms (β=.45, p=.02). Results from this preliminary study suggest that adjunctive intervention produces more rapid treatment response compared with traditional ERP alone. Accommodation is a potentially important target for improving treatment in OCD and other diagnostic groups where accommodation is likely to occur.

The impact of symptom dimensions on outcome for exposure and ritual prevention therapy in obsessive-compulsive disorder

ObjectiveObsessive-compulsive disorder (OCD) is a severe condition with varied symptom presentations. The behavioral treatment with the most empirical support is exposure and ritual prevention (EX/RP). This study examined the impact of symptom dimensions on EX/RP outcomes in OCD patients. MethodThe Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) was used to determine primary symptoms for each participant. An exploratory factor analysis (EFA) of 238 patients identified five dimensions: contamination/cleaning, doubts about harm/checking, hoarding, symmetry/ordering, and unacceptable/taboo thoughts (including religious/moral and somatic obsessions among others). A linear regression was conducted on those who had received EX/RP (n=87) to examine whether scores on the five symptom dimensions predicted post-treatment Y-BOCS scores, accounting for pre-treatment Y-BOCS scores. ResultsThe average reduction in Y-BOCS score was 43.0%, however the regression indicated that unacceptable/taboo thoughts (β=.27, p=.02) and hoarding dimensions (β=.23, p=.04) were associated with significantly poorer EX/RP treatment outcomes. Specifically, patients endorsing religious/moral obsessions, somatic concerns, and hoarding obsessions showed significantly smaller reductions in Y-BOCS severity scores. ConclusionsEX/RP was effective for all symptom dimensions, however it was less effective for unacceptable/taboo thoughts and hoarding than for other dimensions. Clinical implications and directions for research are discussed.

An open trial of videoconference-mediated exposure and ritual prevention for obsessive-compulsive disorder

The gold-standard treatment for OCD is exposure and ritual prevention (ERP), yet despite its well-established efficacy, only a small percentage of OCD patients have access to this treatment. Remote treatments (e.g., videoconferencing) are becoming increasingly popular avenues for treatment delivery and show promise in increasing patient access to evidence-based mental health care. The current pilot study utilized an open trial to examine the feasibility and preliminary efficacy of videoconference-mediated, twice weekly, ERP for adults (n=15) with OCD. Results revealed that ERP was associated with significant improvements in OCD symptoms and large within-group effect sizes. Among the 10 individuals who completed a 3-month follow-up assessment, 30% of participants no longer met DSM-IV-TR criteria for OCD and 80% of participants were rated as very much or much improved on the CGI. This study adds to the growing body of literature suggesting that videoconference-based interventions are viable alternatives to face-to-face treatment.

Cognitive-Behavioral Therapy vs Risperidone for Augmenting Serotonin Reuptake Inhibitors in Obsessive-Compulsive Disorder

Obsessive-compulsive disorder (OCD) is one of the world's most disabling illnesses according to the World Health Organization. Serotonin reuptake inhibitors (SRIs) are the only medications approved by the Food and Drug Administration to treat OCD, but few patients achieve minimal symptoms from an SRI alone. In such cases, practice guidelines recommend adding antipsychotics or cognitive-behavioral therapy consisting of exposure and ritual prevention (EX/RP). To compare the effects of these 2 SRI augmentation strategies vs pill placebo for the first time, to our knowledge, in adults with OCD. A randomized clinical trial (conducted January 2007-August 2012) at 2 academic outpatient research clinics that specialize in OCD and anxiety disorders. Patients (aged 18-70 years) were eligible if they had OCD of at least moderate severity despite a therapeutic SRI dose for at least 12 weeks prior to entry. Of 163 who were eligible, 100 were randomized (risperidone, n = 40; EX/RP, n = 40; and placebo, n = 20), and 86 completed the trial. While continuing their SRI at the same dose, patients were randomized to the addition of 8 weeks of risperidone (up to 4 mg/d), EX/RP (17 sessions delivered twice weekly), or pill placebo. Independent assessments were conducted every 4 weeks. The Yale-Brown Obsessive Compulsive Scale (Y-BOCS) to measure OCD severity. Patients randomized to EX/RP had significantly greater reduction in week 8 Y-BOCS scores based on mixed-effects models (vs risperidone: mean [SE], -9.72 [1.38]; P < .001 vs placebo: mean [SE], -10.10 [1.68]; P < .001). Patients receiving risperidone did not significantly differ from those receiving placebo (mean [SE], -0.38 [1.72]; P = .83). More patients receiving EX/RP responded (Y-BOCS score decrease ≥25%: 80% for EX/RP, 23% for risperidone, and 15% for placebo; P < .001). More patients receiving EX/RP achieved minimal symptoms (Y-BOCS score ≤12: 43% for EX/RP, 13% for risperidone, and 5% for placebo; P = .001). Adding EX/RP was also superior to risperidone and placebo in improving insight, functioning, and quality of life. Adding EX/RP to SRIs was superior to both risperidone and pill placebo. Patients with OCD receiving SRIs who continue to have clinically significant symptoms should be offered EX/RP before antipsychotics given its superior efficacy and less negative adverse effect profile. clinicaltrials.gov Identifier: NCT00389493.

Delivering exposure and ritual prevention for obsessive–compulsive disorder via videoconference: Clinical considerations and recommendations

Exposure and ritual prevention (ERP) has been shown to be effective for treating obsessive–compulsive disorder (OCD), but many people with OCD are not able to access this specialized, evidence-based mental health treatment. Internet-mediated technologies, e.g., videoconferencing, represent a way to increase the availability of evidence-based treatments such as ERP, but given that OCD is a complex disorder requiring a nuanced treatment approach, clinicians attempting to implement ERP remotely should appreciate not only the advantages but also the challenges associated with treating OCD from a distance. Using a case example, we describe this treatment method and discuss relevant clinical considerations.

Patient Adherence to Cognitive-Behavioral Therapy Predicts Long-Term Outcome in Obsessive-Compulsive Disorder

Our prior research demonstrated that patient adherence to homework during cognitive-behavioral therapy (CBT) strongly predicts acute outcome for patients with obsessive-compulsive disorder (OCD).1 To examine whether homework adherence also predicts outcome at 6 month follow-up, we capitalized on data from a clinical trial that provided CBT consisting of exposure and ritual prevention (EX/RP) to 30 adults with OCD, measured homework adherence during acute treatment using a reliable and validated scale, and re-evaluated severity of OCD 6 months later.

Obsessive compulsive personality disorder as a predictor of exposure and ritual prevention outcome for obsessive compulsive disorder

Despite elevated rates of obsessive compulsive personality disorder (OCPD) in patients with obsessive compulsive disorder (OCD), no study has specifically examined comorbid OCPD as a predictor of exposure and ritual prevention (EX/RP) outcome. Participants were adult outpatients (n = 49) with primary OCD and a Yale-Brown Obsessive Compulsive Scale (YBOCS) total score ≥ 16 despite a therapeutic serotonin reuptake inhibitor dose for at least 12 weeks prior to entry. Participants received 17 sessions of EX/RP over 8 weeks. OCD severity was assessed with the YBOCS pre- and post-treatment by independent evaluators. At baseline, 34.7% of the OCD sample met criteria for comorbid DSM-IV OCPD, assessed by structured interview. OCPD was tested as a predictor of outcome both as a diagnostic category and as a dimensional score (severity) based on the total number of OCPD symptoms coded as present and clinically significant at baseline. Both OCPD diagnosis and greater OCPD severity predicted worse EX/RP outcome, controlling for baseline OCD severity, Axis I and II comorbidity, prior treatment, quality of life, and gender. When the individual OCPD criteria were tested separately, only perfectionism predicted worse treatment outcome, over and above the previously mentioned covariates. These findings highlight the importance of assessing OCPD and suggest a need to directly address OCPD-related traits, especially perfectionism, in the context of EX/RP to minimize their interference in outcome.

Patient Utilization of Cognitive-Behavioral Therapy for OCD

The current study examined utilization of cognitive-behavioral therapy (CBT) by individuals receiving treatment for obsessive-compulsive disorder (OCD). Participants were 202 adults with primary DSM-IV OCD who enrolled in a longitudinal, observational study of the course of OCD and completed 2 years of annual follow-up interviews using the Longitudinal Interval Follow-Up Evaluation. One hundred twenty participants reported that a mental health professional recommended CBT for their OCD symptoms at some point during the 2-year follow-up period. One quarter ( n = 31) of these participants did not initiate CBT despite receiving a treatment recommendation. Thirty-one percent of the 89 participants who entered CBT endorsed dropping out of CBT prematurely and less than one third received an adequate “dose” of CBT sessions. Self-reported CBT drop-out rates were significantly greater than attrition rates reported in clinical trials using intensive schedules of exposure and ritual prevention (EX/RP). Perceived environmental barriers and fears regarding treatment participation were the most frequently endorsed reasons for not participating or dropping out of CBT. Despite its efficacy for OCD, many individuals with clinically significant symptoms fail to initiate CBT when recommended by a mental health professional, receive treatments that are less intensive than those used in clinical trials, or drop out of treatment prematurely. Financial costs of CBT, difficulty attending sessions, and fears regarding treatment are significant barriers to initiating and completing therapy.

Treatment of Sexual-Orientation Obsessions in Obsessive-Compulsive Disorder Using Exposure and Ritual Prevention

Presented is a case report of exposure and ritual prevention (EX/RP) therapy administered to a 51-year-old, White, heterosexual male with sexual-orientation obsessions in obsessive-compulsive disorder (OCD). The patient had been previously treated with pharmacotherapy, resulting in inadequate symptom reduction and unwanted side effects. OCD symptoms included anxiety about the possibility of becoming gay, mental reassurance, and avoidance of other men, which resulted in depressive symptoms and marital distress. The patient received 17 EX/RP sessions, administered twice per week. The effect of treatment was evaluated using standardized rating instruments and self-monitoring by the patient. OCD symptoms on the Yale-Brown Obsessive Compulsive Scale (YBOCS) fell from 24 at intake to 3 at posttreatment and to 4 at a 6-week follow-up, indicating minimal symptoms. Improvement also occurred in mood, quality of life, and social adjustment. Issues concerning the assessment and treatment of homosexuality-themed obsessions in OCD are highlighted and discussed.

A Randomized Clinical Trial to Examine Enhancing Cognitive-Behavioral Group Therapy for Obsessive-Compulsive Disorder with Motivational Interviewing and Thought Mapping

Obsessive-compulsive disorder (OCD) is characterized by repeated and persistent attempts to control thoughts and actions with rituals. These rituals are used in order to prevent feared or personally distressing outcomes. Cognitive behavioral group therapy (CBGT) has been reported to be effective for treating OCD patients. However, about one-third (30%) of patients do not benefit from CBGT. Some of these patients do not show significant improvement and continue to use rituals following CBGT, partially because they fail to complete the exposure and ritual prevention (ERP) exercises. Consequently, it is important to motivate patients to fully engage in CBGT treatment and complete the ERP exercises. A randomized behavioral trial examined 12 weeks of manual directed CBGT, with the addition of individual sessions of Motivational Interviewing (MI) and Thought Mapping (TM), and compared treatment outcome to the effectiveness of CBGT group alone. Subjects were randomized (n=93) into a CBGT group or a CBGT group with MI+TM. When the two groups were compared, both groups reduced OCD symptoms. However, symptom reduction and remission were significantly higher in the MI+TM CBGT group. Positive outcomes were also maintained, with additional symptom reduction at the 3-month follow-up for the MI+TM CBGT group. Adding two individual sessions of MI and TM before CBGT successfully reduced OCD symptoms and was more effective than using CBGT group alone.
