BODY FOCUSED REPETITIVE BEHAVIORS (BFRB)
Body-focused repetitive behavior or BFRBs is a general term for a group of related disorders that includes hair pulling, skin picking, and nail-biting. It affects at least 5% of the population. These behaviors are not habits or tics, rather they are complex disorders that cause people to repeatedly touch their hair and body in ways that result in physical damage. Read more about it here.
Treatment includes a combination of a specific type of CBT called Habit Reversal Training (HRT) as well as the comprehensive behavioral (ComB) model which focuses on five domains: Sensory, Cognitive, Affective, Motor and Place (SCAMP).
