Over the past decade, behavioral interventions have become increasingly recognized and recommended as effective first-line therapies for treating individuals with tic disorders. In this article, we describe a basic theoretical and conceptual framework through which the reader can understand the application of these interventions for treating tics. The three primary behavioral interventions for tics with the strongest empirical support (habit reversal, Comprehensive Behavioral Intervention for Tics, and exposure and response prevention) are described. Research on the efficacy and effectiveness of these treatments is summarized along with a discussion of the research evaluating the delivery of these treatments in different formats and modalities. The article closes with a review of the possible mechanisms of change underlying behavioral interventions for tics and areas for future research.

Tics peak in late childhood and decline during adolescence. Yet, for some with Tourette's disorder, tics persist into adulthood. We evaluated childhood predictors of adult tic severity and tic impairment, and change over time. Eighty adolescents/adults were evaluated 11 years following a randomized-controlled trial of behavior therapy. An independent evaluator rated tic severity and tic impairment at baseline, posttreatment, and long-term follow-up. At baseline, parents completed demographics/medical history, and youth tic, internalizing, and externalizing symptom ratings. Youth rated premonitory urge severity and family functioning. After controlling for prior tic treatment effects, female sex and higher tic severity predicted higher tic severity in adulthood; and female sex, no stimulant medication use, higher tic severity, and poorer family functioning predicted higher tic impairment. Higher tic severity and premonitory urge severity predicted smaller reductions in tic severity, whereas higher externalizing symptoms predicted greater reduction in tic severity. Female sex predicted smaller reduction in tic impairment, and externalizing symptoms predicted greater reduction in tic impairment. Female sex and childhood tic severity are important predictors of tic severity and tic impairment in adulthood. Family functioning, premonitory urge severity, and tic severity are important modifiable targets for early or targeted intervention to improve long-term outcomes.

It is not clear whether the development of tics can be prevented. Contextual variables can impact tic expression; therefore, shifting attention to behaviors that reduce tics is an important part of decreasing tic severity. Several medications are effective in reducing tic severity, but side effects restrict their use. Behavioral treatment is the gold standard psychotherapy intervention for tic disorders, with Comprehensive Behavioral Intervention for Tics being the most well-supported nonpharmacological treatment. Although children may be unable to prevent the development of tics, they can still use several strategies to reduce tic severity and impairment.

The present study examined the usability, acceptability, feasibility, and preliminary efficacy of a prototype wrist-worn motion detection device and accompanying mobile app, developed by HabitAware(®), as a system for delivering self-administered Habit Reversal Training (HRT). As an exploratory aim, the effect of the device and HRT app combination was compared to a reminder bracelet. The pilot trial included 15 adults with trichotillomania who interacted with the device and app system (n = 10) or reminder bracelet (n = 5) for 4 weeks. Participants in the device and app condition reported high usability, acceptability, and perceived efficacy of the system. The device and HRT app combination reduced hair pulling severity. Individuals in the reminder bracelet condition also showed a significant improvement in hair pulling. A future efficacy study with a larger sample size, longer timeframe, and improved gesture detection algorithm is warranted.

This chapter explores the treatment of trichotillomania (TTM; also referred to as hair pulling disorder) and Tourette disorder (TD). TTM and TD exist in separate diagnostic categories but exhibit functional similarities and respond to similar treatments. The chapter reviews the characteristics of each disorder. It then describes habit reversal training (HRT) and function-based interventions, which serve as core therapeutic elements in the treatment of both TTM and TD. The chapter also discusses additional treatment strategies that occur as part of standard protocols for both disorders, before looking at the treatment efficacy research. It considers the key features of the manual-based treatments (behavior therapy protocols), as well as ways these protocols can be flexibly implemented for those with TTM and TD. Finally, consistent with the call for “flexibility within fidelity,” the chapter provides an example of a flexible implementation of these treatments.

Objective To determine the long-term durability of behavior therapy for tics among youth with Tourette disorder and persistent (chronic) motor or vocal tic disorders. Method Of the 126 youth who participated in a randomized controlled trial of behavior therapy 11 years prior, 80 were recruited for this longitudinal follow-up. Consenting participants were interviewed in person or remotely (Web-based video) by trained evaluators to determine the course of tics, current tic severity, and tic-related impairment. Recruitment and data collection occurred between 2014 and 2019, with an average follow-up duration of 11.2 years. Results Treatment responders to both conditions in the original trial achieved partial, but not full, tic remission. Tic severity also decreased significantly across the sample, with 40% reporting partial remission. Behavior therapy responders (n = 21) in the original trial were more likely (67%) to achieve remission at follow-up (Total Tic Score = 12.52, SD = 10.75) compared to psychoeducation/supportive therapy responders (n = 6, 0%) at follow-up (Total Tic Score = 20.67, SD = 6.92) on the Yale Global Tic Severity Scale. Tic-related impairment decreased across the sample, with no significant differences between treatment groups or responders. Conclusion Despite limitations of unmeasured variables and veracity of self-report at follow-up, this study supports guidelines recommending behavior therapy as the first-line intervention for tics. Further investigation of behavior therapy as an early preventive intervention also merits attention.

The present study used parent-report data to explore crosscultural similarities and differences in tic severity and reactions to tics across 223 children with Tourette’s disorder (TD) from the United States, United Kingdom, and Netherlands/Norway. Psychometric properties of the TARS-PR and PTQ were also examined and results indicated that both measures may be suitable for assessing tic severity and the consequences of tics in these countries. No differences in parent-reported tic severity were found. However, parents of children with TD from the United Kingdom reported significantly more reactions to their child’s tics than parents from the United States and Netherlands/Norway.Citation - Jordan T.

Habit reversal training (HRT) has been a mainstay of behavior analysts' repertoire for nearly the last 50 years. HRT has been effective in treating a host of repetitive behavior problems. In the face of the current coronavirus pandemic, HRT has practical public health importance as a possible intervention for reducing hand-to-head behaviors that increase the risk of viral infection. The current paper provides a brief review of HRT for hand-to-head habits that is designed for a broad audience and concludes with practical suggestions, based on HRT, for reducing face-touching behaviors.

Children with persistent (chronic) tic disorders (PTDs) experience impairment across multiple domains of functioning, but given high rates of other non-tic-related conditions, it is often difficult to differentiate the extent to which such impairment is related to tics or to other problems. The current study used the Child Tourette's Syndrome Impairment Scale - Parent Report (CTIM-P) to examine parents' attributions of their child's impairment in home, school, and social domains in a sample of 58 children with PTD. Each domain was rated on the extent to which the parents perceived that impairment was related to tics versus non-tic-related concerns. In addition, the Yale Global Tic Severity Scale (YGTSS) was used to explore the relationship between tic-related impairment and tic severity. Results showed impairment in school and social activities was not differentially attributed to tics versus non-tic-related impairment, but impairment in home activities was attributed more to non-tic-related concerns than tics themselves. Moreover, tic severity was significantly correlated with tic-related impairment in home, school, and social activities, and when the dimensions of tic severity were explored, impairment correlated most strongly with motor tic complexity. Results suggest that differentiating tic-related from non-tic-related impairment may be clinically beneficial and could lead to treatments that more effectively target problems experienced by children with PTDs.

BACKGROUND: Trichotillomania (TTM) onset may occur across the lifespan; however, adolescent onset is most frequently reported. Several studies have explored clinical differences between TTM age of onset groups with mixed results. We investigated empirically defined age of onset groups in adults with TTM and clinical differences between groups. METHODS: Participants were 1604 adult respondents to an internet survey, who endorsed DSM-IV-TR TTM criteria. Latent profile analysis was performed to identify TTM age of onset subgroups, which were then compared on demographic and clinical features. RESULTS: The most optimal model was a two-class solution comprised of a large group with average TTM onset during adolescence (n = 1539; 95.9% of the sample; Mean age of onset = 12.4 years) and a small group with average onset in middle adulthood (n = 65; 4.1% of the sample; Mean age of onset = 35.6 years). The late-onset group differed from the early-onset group on several clinical variables (e.g., less likely to report co-occurring body-focused repetitive behaviors). CONCLUSIONS: Findings suggest the presence of at least two distinct TTM age of onset subgroups: an early-onset group with onset during adolescence and a late-onset group with onset in middle adulthood. Future research is needed to further validate these subgroups and explore their clinical utility.
