[Show abstract][Hide abstract] ABSTRACT: BACKGROUND: Recognized since antiquity, only within the last decade has the subject of trichotillomania provoked any larger clinical interest since it has been included in the DSM-IV-TR (The Diagnostic and Statistical Manual of Mental Disorders 4th Text Revision) as a disturbance of the impulse-control disorders not elsewhere classified. Recent data estimates its prevalence at around 3%. Although more common than it was imagined before, clinical and therapeutic aspects are still not well defined. OBJECTIVE: Systematic revision in the literature of several aspects of trichotillomania and its clinical and practical theory. METHOD: The term "trichotillomania", "its epidemiology", "clinical characteristics", "etiology", "comorbidity" and "treatment" were searched in the data bases of Medline/ PubMed, Lilacs, PsycINFO and Cochrane Library. RESULTS: Research with no clinical populations suggests that TTM is more common than it was previously suspected. Phenomenological and taxonomical aspects, comorbidity as well as therapeutic possibilities are discussed. CONCLUSION: Despite a growing number of recent studies, clinical and therapeutic aspects remain undefined. Based on this literature's review, directions are suggested concerning diagnosis, treatment and future research.

[Show abstract][Hide abstract] ABSTRACT: To date, trichotillomania prevalence and phenomenology have not received enough attention in European culture. Although trichotillomania occurs on a severity continuum, few studies evaluated it within non-clinical samples. Studies examining trichotillomania have varied in the criteria used to establish a diagnosis, making it difficult to estimate current prevalence rates. The present study assessed hair-pulling prevalence at varying levels of diagnostic stringency, affective states during the hair-pulling cycle, pulling sites, and environmental cues most frequently endorsed in an Italian non-clinical sample.Five-hundred and twenty non-clinical subjects completed an ad-hoc self-report measure assessing hair-pulling phenomenology. Hair-pulling prevalence was 16.5% when only non-cosmetic hair avulsion was considered and 2.1% when adding the achievement of both criteria B and C of DSM-IV-TR. A decrease in tension after pulling, but not an increase when attempting to resist the urge to pull emerged; positive affective states were experienced also following hair-pulling, not only during hair-pulling. Scalp and eyebrows, and studying/reading, watching TV and speaking on the phone were the pulling sites and the environmental cues most frequently endorsed, respectively. The present prevalence ratios are comparable with those reported in literature suggesting that criteria B and C might be too restrictive, and supporting their removal from DSM-5.
