IntroductionNervous habits also identified as body-focused repetitive behaviors (BFRBs) are behaviors that occur repeatedly in situations and consist of unwanted repetitive, manipulative, problematic, and/or destructive behaviors directed toward the body such as hand-to-head behaviors (e.g., hair pulling or twirling), hand to mouth (e.g., nail biting, thumb sucking), hand to body (e.g., picking at skin, scratching skin) and oral behaviors (e.g. teeth grinding, mouth biting) and are often considered to play a role in emotion regulation and can arise during periods of high tension (Miltenberger, 2005; Roberts, O'Connor, Bélanger, 2013 ; Woods & Miltenberger, 1995). The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, identifies body-focused repetitive behaviors among other specified obsessive-compulsive disorders and related disorders as a behavior that may cause stress and impairment in areas of functioning, yet does not meet all diagnostic criteria of specific obsessive disorders. compulsive and related disorders (American Psychiatric Association 2013, pp. 263-264). Roberts et al. (2013) states that “research on BFRBs has been limited compared to research on other psychiatric conditions.” An example provided by Roberts et al. (2013) referred to the Psychlit database which between 1975 and 2000 contained 2489 articles related to bipolar disorder, 309 articles related to trichotillomania and only fourteen related to BFRBs. Robert et al. (2013) recognize that there is growing interest in BFRBs and that hair pulling and skin picking receive the most research attention (2013).
