Which of the following treatment modalities are used in the treatment of tics, hair pulling and nail biting?

Habit disorder is the term used to describe several related disorders linked by the presence of repetitive and relatively stable behaviors that seem to occur beyond the awareness of the person performing the behavior. The first group of habit disorders is tic disorders (TDs). Tics are involuntary movements, sounds, or words that are "sudden, rapid, recurrent, nonrhythmic". In addition to TDs, body-focused behaviors, such as recurrent hair pulling (trichotillomania ) and skin picking (SP), and nail biting are also included within the habit disorders.
