Part II of the European clinical guidelines for Tourette syndrome and other tic disorders (ECAP journal, 2011) provides updated information and recommendations for psychological interventions for individuals with tic disorders, created by a working group of the European Society for the Study of Tourette Syndrome (ESSTS). A systematic literature search was conducted to obtain original studies of psychological interventions for tic disorders, published since the initial European clinical guidelines were issued. Relevant studies were identified using computerized searches of the MEDLINE and PsycINFO databases for the years 2011–2019 and a manual search for the years 2019–2021. Based on clinical consensus, psychoeducation is recommended as an initial intervention regardless of symptom severity. According to a systematic literature search, most evidence was found for Habit Reversal Training (HRT), primarily the expanded package Comprehensive Behavioral Intervention for Tics (CBIT). Evidence was also found for Exposure and Response Prevention (ERP), but to a lesser degree of certainty than HRT/CBIT due to fewer studies. Currently, cognitive interventions and third-wave interventions are not recommended as stand-alone treatments for tic disorders. Several novel treatment delivery formats are currently being evaluated, of which videoconference delivery of HRT/CBIT has the most evidence to date. To summarize, when psychoeducation alone is insufficient, both HRT/CBIT and ERP are recommended as first-line interventions for tic disorders. As part of the development of the clinical guidelines, a survey is reported from ESSTS members and other tic disorder experts on preference, use and availability of psychological interventions for tic disorders.

Obsessive-compulsive disorder (OCD) is characterized by distressing thoughts and repetitive behaviors that are interfering, time-consuming, and difficult to control. Although OCD was once thought to be untreatable, the last few decades have seen great success in reducing symptoms with exposure and response prevention (ERP), which is now considered to be the first-line psychotherapy for the disorder. Despite these significant therapeutic advances, there remain a number of challenges in treating OCD. In this review, we will describe the theoretical underpinnings and elements of ERP, examine the evidence for its effectiveness, and discuss new directions for enhancing it as a therapy for OCD.

Although exposure and response prevention (EX/RP) is recommended as a first-line treatment for obsessive-compulsive disorder (OCD), responses vary among patients. This study was the first to use network analysis to examine how OCD symptom networks change with EX/RP and vary across different progress trajectories. Data from four clinical trials with 334 adults with OCD who received manualized EX/RP were pooled. The Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) was administered at baseline, midpoint, and post-treatment. OCD symptom networks were constructed using individual Y-BOCS items at these three time points, both for the entire sample and for three different progress trajectories (dramatic, moderate, and little-to-no progress) previously identified using growth mixture modeling. Network measures, including global efficiency, modularity, and weighted degree centrality, were computed to quantitatively assess network properties across treatment. Network analysis revealed two distinct modules at baseline: resistance/control and interference/distress. In the full sample, these two modules became integrated over time, as indicated by significant increases in global efficiency and weighted degree centrality and decreases in modularity; at post-treatment, the network shifted toward a fully connected network, and the strength of associations between nodes increased. These changes were most pronounced in the dramatic progress class. Our findings indicated that effective EX/RP treatment was associated with more integrated OCD symptom networks, which may serve as an indicator of treatment response. Future research should examine how these shifts in network connectivity correspond to changes in underlying brain circuitry and/or to early identification of treatment responders.

Background Exposure and response prevention is effective and recommended as the first choice for treating obsessive-compulsive disorders (OCD). Its mechanisms of action are rarely studied, but two major theories make distinct assumptions: while the emotional processing theory assumes that treatment effects are associated with habituation within and between exposure sessions, the inhibitory learning approach highlights the acquisition of additional associations, implying alternative mechanisms like expectancy violation. The present study aimed to investigate whether process variables derived from both theories predict short-term outcome. Method In a university outpatient unit, 110 patients (63 female) with OCD received manual-based cognitive-behavioral therapy with high standardization of the first two exposure sessions. Specifically, therapists repeated the first exposure session identically and assessed subjective units of distress as well as expectancy ratings in the course of exposure sessions. Based on these data, individual scores for habituation and distress-related expectancy violation were calculated and used for prediction of both percentage change on the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) and remission status after 20 therapy sessions. Results In a multiple regression model for percentage change, within-session habituation during the first exposure was a significant predictor, while in a logistic regression predicting remission status, distress-related expectancy violation during the first exposure revealed significance. A path model further supported these findings. Conclusions The results represent first evidence for distress-related expectancy violation and confirm preliminary findings for habituation, suggesting that both processes contribute to treatment benefits of exposure in OCD, and both mechanisms appear to be independent.

Chronic tic disorders may have a huge influence on quality of life. Habit reversal training (HRT) and exposure response prevention (ERP) are effective treatments. In a blinded assessed, open trial, this study evaluates the effectiveness of a newly developed Scandinavian tic treating manual designed to treat adolescents with a chronic tic disorder, combining HRT and ERP. The study compared the efficacy of treatment based on the same manual delivered either individually or in groups. The study was an open randomized controlled clinical trial in which adolescents were randomized to either individual or group therapy. Both therapies included nine sessions. The parents were offered group-based psycho-education. The exclusion criteria were chosen to design a study that would be close to clinical practice. This is the first Scandinavian study that examines the effectiveness of a treatment manual combining HRT and ERP delivered in an individual and group setting. The study showed a significant reduction of the Total Tic score on the Yale Global Tic Severity Scale both in the individual (effect size 1.21) and group setting (effect size 1.38). A total of 66.7% of participants were considered responders. There was no statistical significant difference between the individual and group setting apart from the functional impairment score. The reductions were comparable with those shown in other studies. The participants applied both HRT and ERP, and the majority (36/59) reported an increased post-treatment experience of control. The newly designed Scandinavian manual was equally effective in the individual and group setting with effect sizes comparable with those shown in other studies.

Background Obsessive-Compulsive Disorder (OCD) is characterized by disturbing and unwanted thoughts as well as repetitive and time-consuming behaviors that interfere with performance. Cognitive Behavior Therapy (CBT) has shown to have beneficial effects on reducing OCD symptoms as the first line of treatment. Moreover, Virtual Reality (VR) has been a more feasible and accessible intervention for OCD in recent years. Regarding the point, the objective of this study was to evaluate the effectiveness of virtual reality exposure and response prevention (VRERP) in the treatment of the OCD contamination subtype. Methods A total number of 36 adults with OCD-contamination subtype were registered and randomly assigned to the intervention and control groups. The intervention group received a 60-min CBT including a “contaminated” virtual environment while the control group received CBT as a standardized treatment. Out of these, 29 patients completed the treatment in 12 weekly sessions. The patients completed the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS), Beck Depression Inventory-II (BDI-II), Beck Anxiety Inventory (BAI), Obsessive Beliefs Questionnaire-44(OBQ-44), and World Health Organization Disability Assessment Scale-2 (WHODAS-2) at week 0, week 12 and after 3 months follow-up. Results Based on the results of the repeated measure analysis of variances, the total score of obsession and compulsion subscales of Y-BOCS significantly decreased as a primary outcome in the intervention group ( F  = 60.97, P  < 0.001, partial eta squared = 0.82; F  = 20.46, P  < 0.001, partial eta squared = 0.61; F  = 29.57, P < 0.001, partial eta squared = 0.69; respectively). The total score of BDI-II and BAI was reduced in both groups but there was no significant difference between them (BDI-II: F  = 0.54, P  = 0.47, partial eta squared = 0.02; BAI: F  = 3.12, P  = 0.06, partial eta squared = 0.19). However, there was a significant difference in the OBQ-44 ( F  = 16.78, P  < 0.001, partial eta squared = 0.56) and the total WHODAS-2 score between the groups ( F  = 14.64, P  < 0.001, partial eta squared = 0.53). Conclusions This study demonstrated the effectiveness of VRERP in the treatment of the OCD-contamination subtype. Therefore, VRERP can be used in CBT as an alternative exposure tool.

Objective Exposure and response prevention (ERP) is an effective treatment for individuals with obsessive–compulsive disorder (OCD), yet a substantial number of individuals with OCD do not fully respond to this intervention. Based on emerging experimental and clinical research on acceptance, this study sought to explore whether willingness to experience unpleasant thoughts, emotions, and bodily sensations during ERP was associated with improved treatment response. Methods Two hundred eighty‐eight adults with OCD receiving residential ERP provided self‐rated willingness and other exposure‐related variables during each daily coached ERP session. Obsessive–compulsive and depressive symptom severity was assessed every week. Multilevel modeling was used to study the impact of willingness on treatment outcome during the first 6 weeks of residential care. Results Data indicated that individuals with higher willingness during ERP reported faster symptom reduction during residential treatment, even when controlling for length of stay, psychopharmacological intervention, depression, adherence, and rituals performed during ERP. These results appear to have both statistical and clinical significance. Conclusions Willingness to fully experience unpleasant and unwanted thoughts, emotions, and bodily sensations during exposures appears to be a marker of successful exposure therapy in adults with OCD. Future research should examine how willingness may enhance extinction learning during ERP.

Exposure and response prevention (ERP) therapy, a form of cognitive-behavioral therapy, is a first-line, evidence-based treatment for obsessive-compulsive disorder (OCD) for adults and children. It is effective for the majority of those who engage in it, but treatment adherence can be challenging for some due to the stress involved in the treatment as well as different life circumstances that arise. To help improve treatment adherence, NOCD, a provider of video teletherapy ERP, identifies those at risk of non-adherence using a prediction algorithm trained on a data set of N  = 13,809 and provides targeted peer support interventions by individuals (“Member Advocates”) who successfully completed ERP treatment for OCD. Member Advocates, using lived OCD experience as well as experience with ERP, engage at-risk patients through digital messaging to engage, educate, and encourage patients in the early stages of treatment. From June 2022 to August 2022, N  = 815 patients deemed at risk were reached out to and n  = 251 responded and engaged with the Member Advocates. In the at-risk patients who engaged, the intervention resulted in a significant mean 30.4% more therapy hours completed compared to those who did not engage. Additionally, engaged patients had greater reductions in OCD severity. These results have implications for how data science, digital interventions, and strategic peer-to-peer communication and support can be combined to enhance the effectiveness of treatment.

Tourette syndrome (TS) and other chronic tic disorders (CTD) are prevalent neurodevelopmental disorders, which can have a huge burden on families and society. Behavioral treatment is a first-line intervention for tic disorders. Despite demonstrated efficacy, tic reduction and utilization rates of behavioral treatment remain relatively low. Patient associations point to an urgent need for easy-to-undergo treatments that focus both on tic reduction and improvement of quality of life. To enhance treatment outcome and overcome treatment barriers, this pilot study’s aim was to investigate the feasibility and preliminary results of a brief, intensive group-based treatment. Tackle your Tics is a 4-day intensive and comprehensive group-based program for children and adolescents (9–17 years) with a tic disorder, consisting of exposure and response prevention (ERP) treatment and additional supporting components, such as coping strategies, relaxing activities and parent support. Assessments were performed pre- and post-treatment and at 2 months follow-up, to test outcomes on tic severity and quality of life, and explore premonitory urges, emotional and behavioral functioning and treatment satisfaction (N = 14, of whom 13 completed the treatment). Parents and children rated this treatment positive on a treatment satisfaction questionnaire. On tic severity (Yale Global Tic Severity Scale) and quality of life (Gilles de la Tourette Syndrome Quality of Life Scale for children and adolescents), improvements between pre-treatment and follow-up were found. Intensive ERP in group format is promising as a feasible treatment to improve both tic severity as well as quality of life. Larger controlled trials are needed to establish its effectiveness.

Tics can have a serious impact on the quality of life of children and their families. Behavioural therapy is an evidence-based first line treatment for tic disorders. This randomised controlled trial studied the efficacy of a brief, condensed group-based programme for children with tics (Dutch Trial Registry NL8052, 27 September 2019). Tackle your Tics is a four-day group treatment, including exposure and response prevention and supporting components, delivered by therapists and ‘experts by experience’. We collected outcome measures at baseline (T1), directly post-treatment (T2), and at three- and 6-months follow-up (T3, T4) including tic severity (primary outcome measure), tic-related impairment, quality of life, tic-related cognitions, emotional/behavioural functioning, family functioning, treatment satisfaction and adherence. Outcomes directly post-treatment improved in both the treatment group (n = 52) and waiting list (n = 54), but showed no statistically significant differences between the conditions (differential change over time T1-T2) on tic severity (Yale Global Tic Severity Scale), quality of life (Gilles de la Tourette Syndrome Quality of Life Scale), tic-related cognitions and family functioning. At longer term (T3), again no between-group difference was found on tic severity, but tic-related impairment, quality of life and emotional/behavioural functioning significantly improved in the treatment group compared to the waiting list. Mean treatment satisfaction scores were favourable for both children and parents. Directly posttreatment, Tackle your Tics showed no superior effect compared to waiting list. However, on longer term this brief four-day group treatment was effective in improving tic-related impairment, quality of life and emotional/behavioural functioning.
