A comparison of relaxation training and competing response training to eliminate hair pulling and nail biting

Sleep functioning in adults with trichotillomania (hair-pulling disorder), excoriation (skin-picking) disorder, and a non-affected comparison sample

The present study assessed sleep functioning in Trichotillomania (TTM; Hair-Pulling Disorder) and Excoriation (Skin-Picking) Disorder (ExD), and a non-affected comparison group, and examined the prevalence and correlates of bedtime and sleep-related hair pulling and skin picking. Participants were adult internet survey respondents, who met diagnostic criteria for TTM (N=259), ExD (N=182), or did not meet criteria for these disorders (N=148). Individuals with TTM and ExD endorsed significantly greater sleep disturbance relative to the comparison group, even after controlling for internalizing (anxiety and depression) symptoms. Hair pulling and skin picking severity were not significantly correlated with sleep disturbance after controlling for internalizing symptoms. Pulling and picking during sleep occurred at rates of 13% and 27%, respectively. Picking severity, anxiety and depressive symptoms, and sleep disturbance were significantly increased in those who engaged in picking during sleep relative to those who did not endorse this behavior. No significant differences were found between those endorsing pulling during sleep and those not endorsing this on demographic, clinical, or sleep variables. The present study highlights the potential role of sleep disturbance in TTM and ExD, and the need for further research in this area.

Cognitive-Behavioral Treatment of Trichotillomania, Targeting Perfectionism

Trichotillomania or hair pulling has been considered mainly as a tensionreducing habit. However, other cognitive, emotional, and situational factors have been identified as important in the development andmaintenance of this disorder. The present case study applied habit reversal techniques, with the addition of a cognitive modification of perfectionist beliefs and style of action, in the treatment of a 23-year-old woman. During an 18-week period, her hair-pulling behavior decreased from a mean of 24 hairs pulled each day to 1 hair pulled overall in a week. A 1.5-year follow-up showed that the client suffered a small relapse during a period of 2 weeks. A self-imposed return to cognitive and behavioral techniques eliminated further pulling. This single case report raises the possibility that perfectionismmay be an important target for cognitive-behavioral treatment intervention in habit disorders such as trichotillomania.

Prototype awareness enhancing and monitoring device for trichotillomania

Trichotillomania is an impairing condition that involves repetitive hair pulling. Habit reversal therapy is helpful for many persons with this disorder. Unfortunately, habit reversal therapy is not helpful for everyone and maintenance of gains is often problematic. Successful habit reversal therapy requires the individual to be aware of hair pulling and handling. Unfortunately, most people with trichotillomania report that much of their plucking occurs outside of awareness. Monitoring of trichotillomania behaviors is also problematic. The present project involved a pilot study of a prototype awareness enhancing and monitoring device aimed at increasing the effectiveness of habit reversal therapy. The device included a watch, bracelet, magnetic necklace, and a pager that was hard-wired for remote activation of a vibrating alert when hair pulling behaviors occurred. Following structured diagnostic assessment, three female participants were randomly assigned to be initially observed for varied lengths of time without the device followed by observation with the device in place. The results indicated a marked reduction in trichotillomania behaviors when the device was in place. Semi-structured interviews revealed that the device was very effective in enhancing awareness and monitoring of trichotillomania related behaviors and enthusiastic acceptance of the device was provided by all participants.

Combination therapy reduces self-injurious behavior in a chimpanzee (Pan Troglodytes Troglodytes): a case report

Self-injurious behavior (SIB) remains a severe and intractable abnormal behavior for nonhuman primates in diverse settings and is a significant concern for veterinarians and behavioral scientists. To date, no single pharmacological, behavioral, social, or environmental intervention method has emerged as a reliable permanent cure for treating SIB in all, or even most, individuals. Implementation and evaluation of a combination therapeutic approach to treating SIB for nonhuman primates is rare. In May 2004, a 25-year-old male chimpanzee with severe SIB (M = 2.09 episodes/day, range = 1-4 episodes/day) underwent intensive behavioral intervention that utilized a combination of techniques. The combination therapy approach entailed the following: (a) pharmacological intervention with a gamma-aminobutyric acid (GABA) analogue to treat suspected HIV-related sensory neuropathic pain, (b) positive reinforcement training, and (c) environmental enrichment, as well as social and environmental modification. The severity of SIB warranted immediate implementation of intensive combination therapy rather than a systematic evaluation of the individual treatment options. The individually tailored, multifaceted combination therapy resulted in the virtual elimination of SIB in this chimpanzee over a 2-year period.

Diagnosis and management of trichotillomania in children and adolescents

Trichotillomania (TTM), a disorder characterized by the repeated non-cosmetic pulling out of hair from any part of the body, was first described in 1889. The disorder can be associated with serious social and psychologic dysfunction, as well as medical problems. A large proportion of the published scientific literature on TTM consists of case reports, and the disorder has only received significant clinical and research attention over the last 20 years. The disorder occurs across age groups and tends to follow a chronic course in the majority of cases. There is evidence for a bimodal onset, with peaks in the pre-school years and in early adolescence. TTM in child and adolescent populations has not been extensively studied, and the etiology, natural course, and best treatment approaches for the disorder are not known. Assessment for TTM in children and adolescents focuses on making the diagnosis and documenting the response to treatment. Despite the lack of validity studies in child and adolescent populations, most assessments for TTM use one or more formal TTM measures. Although classified as an impulse control disorder in the Diagnostic and Statistical Manual of Mental Disorders (4th Edition), there is some controversy about making the diagnosis in child populations because of criteria B (pattern of rising tension prior to pulling) and C (relief after pulling). There is no consensus for the treatment of TTM in children and adolescents. As in adults, a variety of interventions have been reported, including dynamic therapy, behavioral therapy, and psychopharmacology. Use of pharmacologic interventions in the pre-school age group is rare, but becomes more common as the child ages into adolescence. The most frequently used agents include clomipramine, fluoxetine, and paroxetine. The effectiveness of psychopharmacologic interventions for TTM in children and adolescents is, at best, mixed. A multiple modal approach that includes behavioral, pharmacologic, and other therapies may be the best strategy. There have been no controlled treatment trials in child and adolescent populations. Case reports favor a behavioral approach as the first-line single modality of treatment. Controlled studies of single modalities and combined treatment approaches are clearly needed.

Psychodynamics of onychophagists

The authors offer three interpretations of onychophagia, a widespread but largely unstudied phenomenon. The first is phenomenological, and characterises onychophagia as a non-pathological behavioural symptom present in many pathologies and a distinct syndrome that is sometimes quite severe. The second is clinical, and indicates the convergent and divergent connections between onychophagia and the most frequent eating disorders. The third is psychodynamic, and suggests an interpretative hypothesis of onychophagia itself and the frequent sensation of trouble and refusal that it often provokes even in doctors and psychotherapists.

Acceptability of treatments for trichotillomania. Effects of age and severity

Based on the literature, trichotillomania (TTM, chronic hair pulling) in children and adults appears to be responsive to behavioral interventions such as habit reversal. However, some have questioned the generality and acceptability of such procedures. This study compared the acceptability ratings of four interventions targeting TTM (habit reversal, hypnosis, medication, and punishment). In the study, 233 college students read case vignettes in which the age of the analogue client and the severity of the hair pulling were manipulated. Results showed significant differences between the four treatment conditions, with hypnosis and habit reversal being rated most acceptable. Age of the analogue client and severity of TTM did not significantly influence acceptability ratings.

Trichotillomania: current issues in conceptualization and treatment

Trichotillomania is a little-known disorder with wider prevalence and more significant consequences than previously believed. While sharing similarities with obsessive-compulsive disorder, compelling differences from it have also been noted. This fact, coupled with recognized overlap with other obsessive-compulsive spectrum disorders, has resulted in the ongoing evolution of our conceptualization of this illness. While empirical evidence supports the use of behavioral treatment and pharmacotherapy, considerable research is still needed before we can promise highly effective interventions tailored to the individual hairpuller. This review will summarize the evidence supporting, as well as challenging, a hypothesized link with obsessive-compulsive disorder. Current treatment approaches will be reviewed, as well as evidence for their efficacy. Suggestions will be made for future directions in this field.

Chronic nailbiting: a controlled comparison of competing response and mild aversion treatments

Recent studies have suggested that competing response, an abridged version of Azrin and Nunn's (1973) habit reversal method (Behaviour Research and Therapy, 11, 619-628), is a key component in the treatment of chronic nailbiting (Horne & Wilkinson, 1980, Behaviour Research and Therapy, 18, 287-291; Silber & Haynes, 1992, Behaviour Research and Therapy, 30, 15-22). This study replicated and extended the latter by adding an 8 week follow-up period and by using a non-student sample. Forty-five chronic nailbiter Ss were divided into three experimental groups. One method involved the use of mild aversion in which Ss painted a bitter substance on their nails. A second method required the subject to perform a competing response whenever they had the urge to nailbite or found themselves biting their nails. Both methods included self-monitoring of the behaviour and a third group of Ss performed self-monitoring alone as a control condition. The study lasted 12 weeks. Mild aversion resulted in significant improvements in nail length, with the competing response method just failing to show significance in this regard. There was no significant improvement for the control group. The implications for further study and the benefits of competing response in the light of these findings are discussed in terms of treatment success and use of therapist time.

Oral parafunctions as temporomandibular disorder risk factors in children

Oral parafunctions are generally considered to be important factors in the etiology of temporomandibular disorders (TMDs) and many reports have been published about their prevalence in adults and schoolchildren. However, few have included significant numbers of children below the age of 7. The aim of this study was to examine the association between parafunctions and oral/facial TMD-related pain in preschool children. Bruxism, nail biting, and thumb sucking were found to be significantly associated with important oral/facial pain symptoms of clinical interest in the diagnoses of TMD indicating that those parafunctions are risk factors. The study included 525 4- to 6-year-old African-American and Caucasian children, mean age 5.1 +/- 0.65 (SD). An alpha level of 5% was chosen for comparison with a Pearson Chi-Square test. Bonferroni correction was made and a p-value of < 0.005 was accepted as significance level. Only 28% of the children had no history of any parafunction. More girls (82%) than boys (63%) in the Caucasian subgroup had at least one parafunction (p approximately 0.00017). No such difference was found in the African-American subgroup where the corresponding figures were 71% for girls and 73% for boys. Thumb sucking was reported by 57% of the children, more often by Caucasian girls (69%) than by Caucasian boys (43%) (p < 0.00001). Thirty percent still had the habit. Forty-one percent had a history of nail biting. Bruxism was noted in 20% of the children, but occurred mostly in combination with other parafunctions and was seldom (in 3.4%) the only parafunction. Of the 10 pain variables, bruxism was significantly associated with eight, thumb sucking with three, and nail biting with two. Analysis with logistic regression confirmed the results. Association does not, however, tell if a parafunction is the cause or the consequence of pain, or if a third factor is causing both pain and increased prevalence of oral parafunctions. Further prospective longitudinal studies including higher age groups are needed to clarify those relations and to determine if there are long-term effects of childhood parafunctions.

Association between CMD signs and symptoms, oral parafunctions, race and sex, in 4-6-year-old African-American and Caucasian children

The associations between oral parafunctions, signs and symptoms of craniomandibular disorders (CMD), race, and sex were analysed in recordings from 203 4-6-year-old African-American and Caucasian children. Significant correlations were found between bruxism, nail biting, thumb sucking and most of the CMD signs and symptoms. There were also significant associations between most of the signs and symptoms and race, while significant association with sex was found only regarding headache, TMJ sounds and chewing pain. Significant associations were found between most CMD signs and TMJ sounds supporting the view that joint sound recordings have diagnostic value. There were also significant associations between the pain variables recorded by questionnaire and those recorded by palpation, which indicates that reliable data can be obtained by interviewing children as young as five. The results of this study support the concept that oral parafunctions have a significant role in the aetiology of CMD. The results also show that race and sex need to be considered when analysing the possible aetiological role of oral parafunctions in CMD. Longitudinal studies, beginning with low age groups are needed to better determine the role of childhood oral parafunctions in CMD aetiology.

Trichotillomania

The present study examines some of the beliefs about trichotillomania such as those concerning the sex and age of afflicted individuals. Information was gathered from an exhaustive literature review and surveys of the general public and college students. Data on such factors as prevalence, sex, age distribution, onset, codiagnosis, and details of the hair-pulling act are presented, and reviews of explanations and treatment are provided.

Pathologic hair-pulling: a review of the literature and case reports

Pathologic hair-pulling (trichotillomania) has been described in the dermatologic and psychiatric literature for the last century, but has become the focus of increased attention in the last few years. Once thought to be either a wholly benign condition or a symptom of obsessive-compulsive disorder, more recently hair-pulling has been noted in the context of numerous types of psychopathology, and has been reported to respond to several different types of intervention, both psychological and somatic. Estimates of its prevalence have varied widely. Because of the disparate conclusions of the literature on this condition, a more careful assessment of diagnostic validity is recommended.

Dermatology and conditions related to obsessive-compulsive disorder

Patients with cutaneous disorders may have obsessive-compulsive symptoms but treatment for these symptoms has been limited. Advances in our understanding of obsessive-compulsive disorders have led to the concept of a spectrum with similar phenomenology, underlying neurobiology, and psychopharmacotherapeutic response. Many of these disorders, which include trichotillomania, neurotic excoriation, onychophagia, body dysmorphic disorder, and dermatitis artefacta may respond to specific therapeutic interventions.

Treating nailbiting: a comparative analysis of mild aversion and competing response therapies

This study compared two methods of treating nail-biting. One method involved the use of a mild aversive stimulus in which subjects painted a bitter substance on their nails, and the other required the subject to perform a competing response whenever they had the urge to bite or found themselves biting their nails. Both methods included self-monitoring of the behaviour, and a third group of subjects performed self-monitoring alone as a control condition. The study lasted four weeks. Twenty-one subjects, seven per group, participated. Both methods resulted in significant improvements in nail length, with the competing response method showing the most beneficial effect. There was no significant improvement for the control group. The competing response condition also yielded significant improvements along other dimensions such as degree of skin damage and subjects own ratings of their control over their habit. These were not seen for the other two conditions. The benefits of this abridged version of Azrin and Nunn's (Behaviour Research and Therapy, 11, 619-628, 1973) habit reversal method in terms of treatment success, use of therapist time and client satisfaction, are discussed.

Trichotillomania in children and adolescents: review of the literature and case report

Hair pulling is an uncommon behavior for which a standard treatment modality has not yet been established; additionally its prognosis is generally guarded. This article reviews the literature and comments upon the demographic, dermatologic, clinical and psychodynamic features of trichotillomania. The various diagnostic association and the treatment approaches are discussed. A case of trichotillomania is presented and the possible relationship between trichotillomania and anxiety is explored.

A double-blind comparison of clomipramine and desipramine in the treatment of trichotillomania (hair pulling)

Trichotillomania, an irresistible impulse to pull out one's own hair, is a chronic psychiatric illness that causes severe discomfort, interferes with daily activities, and leads to social isolation. Treatment is usually unsatisfactory. Thirteen women with severe trichotillomania completed a 10-week double-blind, crossover trial of clomipramine, a new tricyclic antidepressant agent with selective antiobsessional effects, and desipramine, a standard tricyclic antidepressant. Treatment with clomipramine resulted in significantly greater improvement in symptoms than desipramine, as indicated by physicians' ratings of the women's clinical progress on a scale in which lower scores indicate improvement (mean [+/- SD] scores: at base line, 10.0; after desipramine treatment, 8.7 +/- 2.4; after clomipramine treatment, 4.7 +/- 3.1; P = 0.006) and by scores on a trichotillomania-impairment scale, in which higher scores indicate greater impairment (at base line, 6.8 +/- 1.7; after desipramine treatment, 6.2 +/- 1.7; after clomipramine treatment, 4.2 +/- 2.7; P = 0.03). The severity of symptoms (mean base-line score, 15.9 +/- 3.8) was reduced more by clomipramine (10.6 +/- 6.4) than by desipramine (14.4 +/- 3.9). The patients reported that the compulsion decreased in intensity and that they were more able to resist the urge to pull out their hair during treatment with clomipramine. We conclude that clomipramine appears to be effective in the short-term treatment of trichotillomania.

Trichotillomania and incest

Trichotillomania is reported in a 33-year-old female victim of incest, with a possible causal connection.
