Based on a review using the new criteria for empirically supported treatments, this chapter emphasizes exposure with response prevention for obsessive-compulsive disorder, a treatment that has strong research support. Cognitive therapy is also discussed. Credible components of treatment include exposure, behavioral experiments, and cognitive reappraisal. A sidebar also reviews treatments for body dysmorphic disorder, hoarding disorder, trichotillomania, and excoriation.
Trichotillomania and skin picking disorder have been characterized as body-focused repetitive behavior (BFRB) disorders (i.e., repetitive self-grooming behaviors that involve biting, pulling, picking, or scraping one’s own hair, skin, lips, cheeks, or nails). Trichotillomania and skin picking disorder have also historically been classified, by some, as types of compulsive self-injury as they involve repetitive hair pulling and skin picking, respectively. The question of the relationship of these disorders to more conventional forms of self-injury such as cutting or self-burning remains incompletely investigated. The objective of this study was to examine the relationship of these two disorders with non-suicidal self-injury (NSSI).
Methods
Adults with trichotillomania (n = 93) and skin picking (n = 105) or both (n = 82) were recruited from the general population using advertisements and online support groups and completed an online survey. Participants completed self-report instruments to characterize clinical profiles and associated characteristics. In addition, each participant completed a mental health history questionnaire.
Results
Of the 280 adults with BFRB disorders, 141 (50.1%) reported a history of self-injury independent of hair pulling and skin picking. Participants with a history of self-injury reported significantly worse pulling and picking symptoms (p < .001) and were significantly more likely to have co-occurring alcohol problems (p < .001), borderline personality disorder (p < .001), buying disorder (p < .001), gambling disorder (p < .001), compulsive sex behavior (p < 001), and binge eating disorder (p = .041).
Conclusions
NSSI appears common in trichotillomania and skin picking disorder and may be part of a larger constellation of behaviors associated with impulse control or reward-related dysfunction.
Trichotillomania (TTM) is a mental health disorder characterized by repetitive urges to pull out one’s hair. Cognitive deficits have been reported in people with TTM compared to controls; however, the current literature is sparse and inconclusive about affected domains. We aimed to synthesize research on cognitive functioning in TTM and investigate which cognitive domains are impaired.
Methods
After preregistration on the International Prospective Register of Systematic Reviews (PROSPERO), we conducted a comprehensive literature search for papers examining cognition in people with TTM versus controls using validated tests. A total of 793 papers were screened using preestablished inclusion/exclusion criteria, yielding 15 eligible studies. Random-effects meta-analysis was conducted for 12 cognitive domains.
Results
Meta-analysis demonstrated significant deficits in motor inhibition and extradimensional (ED) shifting in people with TTM versus controls as measured by the stop-signal task (SST) (Hedge’s g = 0.45, [CI: 0.14, 0.75], p = .004) and ED set-shift task (g = 0.38, [CI: 0.13, 0.62], p = .003), respectively. There were no significant between-group differences in the other cognitive domains tested: verbal learning, intradimensional (ID) shifting, road map spatial ability, pattern recognition, nonverbal memory, executive planning, spatial span length, Stroop inhibition, Wisconsin card sorting, and visuospatial functioning. Findings were not significantly moderated by study quality scores.
Conclusions
Motor inhibition and ED set-shifting appear impaired in TTM. However, a cautious interpretation of results is necessary as samples were relatively small and frequently included comorbidities. Treatment interventions seeking to improve inhibitory control and cognitive flexibility merit exploration for TTM.
Prevalence estimates for body-focused repetitive behaviors (BFRBs) such as trichotillomania differ greatly across studies owing to several confounding factors (e.g. different criteria). For the present study, we recruited a diverse online sample to provide estimates for nine subtypes of BFRBs and body-focused repetitive disorders (BFRDs).
Methods
The final sample comprised 1481 individuals from the general population. Several precautions were taken to recruit a diverse sample and to exclude participants with low reliability. We matched participants on gender, race, education and age range to allow unbiased interpretation.
Results
While almost all participants acknowledged at least one BFRB in their lifetime (97.1%), the rate for BFRDs was 24%. Nail biting (11.4%), dermatophagia (8.7%), skin picking (8.2%), and lip-cheek biting (7.9%) were the most frequent BFRDs. Whereas men showed more lifetime BFRBs, the rate of BFRDs was higher in women than in men. Rates of BFRDs were low in older participants, especially after the age of 40. Overall, BFRBs and BFRDs were more prevalent in White than in non-White individuals. Education did not show a strong association with BFRB/BFRDs.
Discussion
BFRBs are ubiquitous. More severe forms, BFRDs, manifest in approximately one out of four people. In view of the often-irreversible somatic sequelae (e.g. scars) BFRBs/BFRDs deserve greater diagnostic and therapeutic attention by clinicians working in both psychology/psychiatry and somatic medicine (especially dermatology and dentistry).

This chapter provides a concise but comprehensive overview of body focused repetitive behaviors (BFRBs), focusing on the two disorders recognized in the American Psychiatric Association’s diagnostic manual (DSM 5), hairpulling disorder (HPD), also known as trichotillomania, and skin picking disorder (SPD), also known as excoriation disorder. It addresses diagnostic issues, causation, demographics, course of the disorders, comorbidity, prevalence, emotional and interpersonal sequelae, and phenomenology. Furthermore, common misconceptions about BFRBs are addressed, providing the reader with a solid information base upon which to build effective treatment.
More common than was previously believed, body-focused repetitive behaviors (BFRBs) affect as many as 1 in 20 people. Written by the experts who created and developed the ComB Model, it provides a practical and user-friendly manual for therapists on an effective, individualized treatment approach for BFRBs. It features the most up-to-date information on BRFBs and guides clinicians from conceptualization of the problem through all aspects of clinical treatment. The internal and external influences for hair-pulling and skin-picking disorders are addressed thoroughly and from a functional analytical perspective. A valuable case example illustrates exactly how specific concepts and techniques are implemented in therapy. Chapters cover preparing the client for treatment, encouraging healthy approaches to hair/skin care, preventing relapse, dealing with co-morbidities, trouble-shooting impediments to therapy and modifying treatment for children, adolescents, and their families. This book is the best single resource available for mental health professionals for conceptualizing and treating BFRBs.
Non-human primates occasionally exhibit behaviours thought to occur only in captivity that are considered abnormal. In particular, hair-plucking behaviour occurs across many species of mammals and birds. This study was the first to assess the phenomenology, demography and aetiology of this behaviour in captive gorillas across the Association of Zoos and Aquariums (AZA) population. A survey was sent to 52 AZA institutions housing western lowland gorillas. Hair-plucking behaviour occurred in 15% of the surveyed population with 62% of institutions housing a hair plucker. Individuals were most likely to self-pluck using their fingers. Individuals that were exposed as youngsters to a hair-plucking group member were significantly more likely to develop the behaviour themselves. There was also a trend toward solitary individuals being more likely to perform this behaviour. Future research needs include identifying hormonal correlates to this behaviour, understanding its relationship to acute or chronic stressors, and examining what causes this behaviour to fluctuate in frequency once it has developed.

Anorexia nervosa is an eating behavior disorder that is often related to various personality factors. The relationship between obsessive compulsive disorder and eating Disorders has been highlighted.
Objectives
To present a clinical case of a patient with eating disorder and gastric bezoar, secondary to compulsive hair ingestion.
Methods
Bibliographic review of articles published in relation to the comorbidity of these disorders, based on articles published in the last 5 years in Pubmed.
Results
26-year-old female. Diagnosis of restrictive anorexia nervosa. She was admitted to the hospital on two occasions for nutritional disorders. In the last admission, she reported greater anxiety and significant weight loss. She reports that she has limited her food intake, but she does feel thin and is unable to eat for fear of gaining weight. Ruminative thoughts about her body image. During admission, the patient expressed a sensation of fullness, nausea and vomiting, later observing in abdominal X-ray and gastroscopy, the presence of a gastric trichobezoar, which was finally resolved conservatively.
Conclusions
Trichotillomania is observerd in 1 in 2000 people, trichophagia is even less frequent. According to DSM- V, these disorders are grouped within obsessive-compulsive spectrum disorders. A Trichobezoar is a conglomerate that can be found in the stomach or intestine, composed mainly of hair, previously ingested. Trichotillomania can be associated with anorexia nervosa, especially in patients with obsessive personality traits, which occurs frequently. The gastric slowing that patients with anorexia often present is a factor that favors the formation of the bezoar
Trichotillomania is characterized by recurrent pulling of one’s hair despite attempts of stopping, resulting in hair loss. Previously classified as impulse control disorder, it is now considered an obsessive-compulsive related disorder in DSM-5. First-line therapy is cognitive behavioural therapy (CBT), with strong support for habit reversal training. For pharmacological therapy, selective serotonin reuptake inhibitors (SSRIs) are commonly prescribed. Clomipramine has been used but is limited by its side effect profile. Many patients continue to experience distressing symptoms despite current treatment methods.
Objectives
Lamotrigine, an anticonvulsant medication, is frequently utilized by psychiatrists to treat conditions like Bipolar Disorder. However, its utility in treating Trichotillomania has not been explored. We are interested to find out if it could benefit patients who have not responded adequately to current available treatment.
Methods
We report a case of a lady suffering from Trichotillomania for many years with limited improvement despite active treatment. We follow her progress after being started on Lamotrigine for six months.
Results
In our case, a lady with longstanding Trichotillomania has previously been treated with SSRIs and Chlomipramine with limited response. An incidental trial of Lamotrigine after stopping her other medications has led to sustained improvement and stabilization of her condition. A possible hypothesis on how Lamotrigine’s mode of action could have led to this improvement will explored in this paper.
Conclusions
This case illustrates the potential of Lamotrigine to treat Trichotillomania in someone who has not responded adequately to usual treatment and could be an area worth looking into for future research.
Trichotillomania is a disorder (estimated prevalence 0.5-2.0%) with common onset in childhood, rarely seen in adulthood, characterized by the repetitive pulling out of one’s own hair leading to hair loss and functional impairment, associated with other comorbidities: major depression (39-65%), anxiety disorder (23-32%), SUDs (15-19%), OCD (13-27%).
Objectives
To present a case of late-onset trichotillomania in a 60-year-old woman.
Methods
The present study is a case report of a patient visited in outpatient psychiatry for trichotillomania. We also searched previously case reports, series and systematic reviews of clinical trichotillomania using a pubmed query.
Results
This is a 60-year-old morbidly obese woman diagnosed with dysthymia, binge eating disorder and histrionic personality disorder. She explained a worsening of anxiety associated with work problems of one year of evolution and, for six months, the beginning of the plucking of eyebrow hairs and scabs to decrease this symptom, with inability to avoid the behaviour and without eating the hairs. The mental evaluation highlighted psychic anxiety, hypothymia, low self-esteem and feelings of failure and did not suggest a delirium. We started treatment with topiramate up to 150mg/day which was not successful. After that we switched to fluoxetine up to 60mg/day associated to psychotherapy observing a slight gradual improvement.
Conclusions
The clinical presentation suggested the diagnosis of trichotillomania in the context of dysthymia. No particular medication demonstrates efficacy in the treatment of trichotillomania. Preliminary evidence suggests treatment effects of clomipramine, NAC and olanzapine based on individual trials with small sample sizes. Research findings also recommend psychotherapy based on habit reversal.
Trichotillomania (TTM), also known as hair pulling disorder, is an obsessive- compulsive disorder characterized by the recurrent, overwhelming urge to repeatedly pull out one’s hair. Hair pulling can occur anywhere on the body but is most common on the scalp, eyebrows, and eyelashes and subsequently results in bald patches. While TTM is a very prevalent, debilitating disorder, there is still no FDA approved treatment that exists.
Objectives
The main objective of this study is to explore the various forms of available psychotherapy available for the treatment of trichotillomania.
Methods
Two independent reviewers conducted title, abstract, full-text searching and data extraction among the PubMed, PsycINFO, and ResearchGate data bases. Of the 79 articles screened, five were included in this review
Results
Habit reversal therapy (HRT) is a form of cognitive behavioral therapy that is considered the first line treatment for management of TTM. Other psychotherapeutic techniques include acceptance and commitment therapy, progressive muscle relaxation, and mindfulness therapy.
Conclusions
This study supports the current data which states that HRT is the first line treatment and there is yet to be a pharmacological treatment of choice for TTM. It is also very important to note that TTM is still underdiagnosed and can be mistaken for a dermatological disorder like alopecia aerata. Furthermore, many people with trichilemmoma have underlying mental health disorders such as anxiety and depression that must first be addressed before treating the hair pulling itself.
Trichotillomania is an obsessive-compulsive spectrum disorder characterized by recurrent and uncontrolled hair pulling. This behavior causes significant anxiety as well as low self-esteem in people who suffer from this disorder. There is still no therapy of proven efficacy in the treatment of trichotillomania. Psychotropic drugs and cognitive behavioral psychotherapy have been tried in the management of this disease, but the relapse rate is high. Narrative therapy is an innovative type of postmodern psychotherapy and in our literary search we have not found data related to its use in the treatment of trichotillomania.
Objectives
To present a novel therapeutic approach to a highly resistant disorder, trichotillomania.
Methods
Case report and literature review.
Results
We present a case of a 39-year-old woman diagnosed with trichoticolomania twenty years earlier. She tried several types of psychotherapies for manage her hair-pulling problem, all related with relapse only a few days after finishing the sessions. We have carried out a total of 5 narrative therapy sessions spread over 3 months. No relapses have been observed during the subsequent 9-month follow-up period.
Conclusions
Based on our experience, we believe that Narrative Therapy is a good and still unexplored alternative for people diagnosed with trichotillomania.
Body-focused repetitive behaviours (BFRBs) such as skin picking and hair pulling are frequent but under-diagnosed and under-treated psychological conditions. As of now, most studies use symptom-specific BFRB scales. However, a transdiagnostic scale is needed in view of the high co-morbidity of different BFRBs.
Aims:
We aimed to assess the reliability as well as concurrent and divergent validity of a newly developed transdiagnostic BFRB scale.
Method:
For the first time, we administered the 8-item Generic BFRB Scale (GBS-8) as well as the Repetitive Body Focused Behavior Scale (RBFBS), modified for adults, in 279 individuals with BFRBs. The GBS-8 builds upon the Skin Picking Scale-Revised (SPS-R), but has been adapted to capture different BFRBs concurrently. A total of 170 participants (61%) were re-assessed after 6 weeks to determine the test–retest reliability of the scale.
Results:
Similar to the SPS-R, factor analysis yielded two dimensions termed symptom severity and impairment. The test–retest reliability of the scale was satisfactory (r = .72, p<.001). Concurrent validity (r = .74) with the RBFBS was good (correlational indexes for concurrent validity were significantly higher than that for discriminant validity).
Discussion:
The GBS-8 appears to be a reliable and valid global measure of BFRBs. We recommend usage of the scale in combination with specific BFRB scales to facilitate comparability across studies on obsessive-compulsive spectrum disorders.
Behaviors typical of body-focused repetitive behavior disorders such as trichotillomania (TTM) and skin-picking disorder (SPD) are often associated with pleasure or relief, and with little or no physical pain, suggesting aberrant pain perception. Conclusive evidence about pain perception and correlates in these conditions is, however, lacking.
Methods
A multisite international study examined pain perception and its physiological correlates in adults with TTM (n = 31), SPD (n = 24), and healthy controls (HCs; n = 26). The cold pressor test was administered, and measurements of pain perception and cardiovascular parameters were taken every 15 seconds. Pain perception, latency to pain tolerance, cardiovascular parameters and associations with illness severity, and comorbid depression, as well as interaction effects (group × time interval), were investigated across groups.
Results
There were no group differences in pain ratings over time (P = .8) or latency to pain tolerance (P = .8). Illness severity was not associated with pain ratings (all P > .05). In terms of diastolic blood pressure (DBP), the main effect of group was statistically significant (P = .01), with post hoc analyses indicating higher mean DBP in TTM (95% confidence intervals [CI], 84.0-93.5) compared to SPD (95% CI, 73.5-84.2; P = .01), and HCs (95% CI, 75.6-86.0; P = .03). Pain perception did not differ between those with and those without depression (TTM: P = .2, SPD: P = .4).
Conclusion
The study findings were mostly negative suggesting that general pain perception aberration is not involved in TTM and SPD. Other underlying drivers of hair-pulling and skin-picking behavior (eg, abnormal reward processing) should be investigated.
Both hair pulling disorder (trichotillomania) and skin picking disorder (excoriation disorder) are legitimate clinical disorders that are neither rare nor benign. For almost half a century, habit reversal training (HRT) has dominated the clinical literature as treatment for these body-focused repetitive behaviors (BFRBs), yet clinicians and researchers have recognized the limitations of this treatment and have utilized numerous treatment modifications in attempts to bolster its effectiveness. Comprehensive behavioral (ComB) treatment, a newer approach to BFRB treatment, has been described in professional publications and is widely used by expert BFRB clinicians The ComB treatment model provides a guiding, comprehensive, conceptual framework that encompasses and integrates sensory, cognitive, affective, motor, and environmental variables into an individualized treatment package geared to the unique clinical phenomenology of each patient. In this chapter, ComB treatment is described in detail and an illustrative case highlights its unique advantages over other BFRB treatments.
Trichotillomania (TTM) and skin picking disorder (SPD) are common and often debilitating mental health conditions, grouped under the umbrella term of body-focused repetitive behaviors (BFRBs). Recent clinical subtyping found that there were three distinct subtypes of TTM and two of SPD. Whether these clinical subtypes map on to any unique neurobiological underpinnings, however, remains unknown.
Methods
Two hundred and fifty one adults [193 with a BFRB (85.5% [n = 165] female) and 58 healthy controls (77.6% [n = 45] female)] were recruited from the community for a multicenter between-group comparison using structural neuroimaging. Differences in whole brain structure were compared across the subtypes of BFRBs, controlling for age, sex, scanning site, and intracranial volume.
Results
When the subtypes of TTM were compared, low awareness hair pullers demonstrated increased cortical volume in the lateral occipital lobe relative to controls and sensory sensitive pullers. In addition, impulsive/perfectionist hair pullers showed relative decreased volume near the lingual gyrus of the inferior occipital–parietal lobe compared with controls.
Conclusions
These data indicate that the anatomical substrates of particular forms of BFRBs are dissociable, which may have implications for understanding clinical presentations and treatment response.
Trichotillomania is a disorder characterized by the compulsive pulling out of one’s own hair. It usually starts just before or after puberty, and about 1 to 2% of people have this disorder. But its incidence is variable over the years and socio-demographic data.
Objectives
Describe the profile of children and adolescents consulting for trichotillomania.
Methods
An incidence survey was carried out among children and adolescents followed for trichotillomania at the out-patient unit of child psychiatry (Monastir - Tunisia) from January 2003 to September 2020.
Results
Among the 11000 patients who were followed during the study period, 47 patients presented trichotillomania, corresponding to a rate of 0.42%. Three of them presented with associated trichophagia and two were operated on in pediatric surgery for trichobezoar. A female predominance was noted with a sex-ratio of 0.37. The average age was 9.3 years with extremes ranging from 2 to 15 years. Almost all of the patients were in school. Most of the patients were referred by dermatologists. We retained in these patients: 17% presented an attachment disorder, 14.8% had a depressive disorder, 6.3% had anxiety elements, 6.3% had an intellectual disability, 4.2% had an associated enuresis and one case had a GAD. The treatment was to undergo behavioral measurements or CBT in 91.4%. Pharmacological management was carried out in 46.8% of patients and was mainly based on antidepressants.
Conclusions
Trichotillomania is a disorder that can be stressful for patients as well as their families. Better knowledge of the profile of these patients is necessary in order to better therapeutic efficacy.
Skin picking disorder and trichotillomania, also characterized as body-focused repetitive behaviors (BFRBs), often lead to functional impairment. Some people with BFRBs, however, report little if any psychosocial dysfunction. There has been limited research as to which clinical aspects of BFRBs are associated with varying degrees of functional impairment.
Methods
Adults (n = 98), ages 18 to 65 with a current diagnosis of trichotillomania (n = 37), skin picking disorder (n = 32), trichotillomania plus skin picking disorder (n = 10), and controls (n = 19) were enrolled. Partial least squares regression (PLS) was used to identify variables associated with impairment on the Sheehan Disability Scale.
Results
PLS identified an optimal model accounting for 45.8% of variation in disability. Disability was significantly related to (in order of descending coefficient size): severity of picking, perceived stress, comorbid disorders (specifically, anxiety disorders / obsessive–compulsive disorder), trait impulsivity, family history of alcohol use disorder, atypical pulling/picking sites, and older age.
Conclusions
At present mental disorders are viewed as unitary entities; however, the extent of impairment varies markedly across patients with BFRBs. These data suggest that whereas symptom nature/severity is important in determining impairment, so too are other variables commonly unmeasured in clinical practice. Outcomes for patients may thus be maximized by rigorously addressing comorbid disorders; as well as integrating components designed to enhance top-down control and stress management. Interestingly, focused picking and emotional pulling were linked to worse disability, hinting at some differences between the two types of BFRBs, in terms of determinants of impairment.
The extent to which obsessive–compulsive and related disorders (OCRDs) are impulsive, compulsive, or both requires further investigation. We investigated the existence of different clusters in an online nonclinical sample and in which groups DSM-5 OCRDs and other related psychopathological symptoms are best placed.
Methods
Seven hundred and seventy-four adult participants completed online questionnaires including the Cambridge–Chicago Compulsivity Trait Scale (CHI-T), the Barratt Impulsiveness Scale (BIS-15), and a series of DSM-5 OCRDs symptom severity and other psychopathological measures. We used K-means cluster analysis using CHI-T and BIS responses to test three and four factor solutions. Next, we investigated whether different OCRDs symptoms predicted cluster membership using a multinomial regression model.
Results
The best solution identified one “healthy” and three “clinical” clusters (ie, one predominantly “compulsive” group, one predominantly “impulsive” group, and one “mixed”—“compulsive and impulsive group”). A multinomial regression model found obsessive–compulsive, body dysmorphic, and schizotypal symptoms to be associated with the “mixed” and the “compulsive” clusters, and hoarding and emotional symptoms to be related, on a trend level, to the “impulsive” cluster. Additional analysis showed cognitive-perceptual schizotypal symptoms to be associated with the “mixed” but not the “compulsive” group.
Conclusions
Our findings suggest that obsessive–compulsive disorder; body dysmorphic disorder and schizotypal symptoms can be mapped across the “compulsive” and “mixed” clusters of the compulsive–impulsive spectrum. Although there was a trend toward hoarding being associated with the “impulsive” group, trichotillomania, and skin picking disorder symptoms did not clearly fit to the demarcated clusters.
