Psychotherapy Treatment can include
behavior modification therapy, medication, and
family therapy. Individual behavioral therapy has been shown as a "probably effective" evidence-based therapy to help with thumb sucking, and possibly nail biting. Another form of treatment that focuses on mindfulness, stimuli, and rewards has proven effective in some people. However, no treatment was deemed well-established to treat any form of BFRBs.
Decoupling Decoupling is a behavioral self-help intervention for body-focused repetitive behavior (BFRB). The user is instructed to modify the original dysfunctional behavioral path by performing a counter-movement shortly before completing the
self-injurious behavior (e.g., biting nails, picking skin, pulling hair). This is intended to trigger an irritation, which enables the person to detect and stop the
compulsive behavior at an early stage. A systematic review from 2012 suggested some efficacy of decoupling, which was corroborated by another study in 2019. Decoupling was shown to be superior to habit reversal training in treating BFRB in one direct comparison study in 2021. ==Prevalence==
