“…Behavioral interventions for TTM (e.g., [44]) have generally included three core elements: first, awareness training, wherein techniques (e.g., self-monitoring) are implemented to improve the patient’s awareness of pulling and, better yet, the patient’s awareness of the urge that precedes pulling; second, stimulus control, which includes a variety of methods that serve as ‘speed bumps’ to reduce the likelihood that pulling behavior begins; and third, competing response training, where patients are taught at the earliest sign of pulling, or of the urge to pull, to engage in a behavior that is physically incompatible with pulling for a brief period of time until the urge subsides. These core methods were initially developed and tested by Azrin and Nunn [47], and comprise the main elements of contemporary behavioral treatment, although some habit reversal training protocols have also included other techniques (e.g., relaxation training and cognitive strategies to address dysfunctional thoughts that precipitate pulling).…”
