“…One reason exposure appeared less effective in the treatment of ExD compared to other OCRDs such as OCD may be that exposure is more effective in targeting distress, whereas Tucker et al (2011) found the majority of people with ExD experience pleasure, gratification, or relief immediately after picking. Some researchers have proposed an addiction model to account for the pleasurable emotional response that people with BFRBs report when engaging in pulling or picking behavior (see Conelea et al, 2017). Oliveirra et al (2019) found that, although ExD exhibits greater diagnostic overlap with OCD compared to behavioral addictions, there was enough of an overlap with gambling addiction to suggest impulsive/addictive features of picking consistent with addiction.…”

This study piloted the use of ACT-informed exposure as an adjunct to habit reversal training (HRT) for excoriation disorder (ExD). Using a nonconcurrent multiple baseline single case design, four participants completed sessions of exposure and HRT. Repeated measures and self-report data were collected on skin picking and psychological flexibility. Two participants completed HRT followed by exposure, and two participants completed exposure followed by HRT. Results support the effectiveness of HRT in reducing picking. Results suggest exposure may have some impact in reducing picking, but effects were weaker compared to HRT. Contrary to predictions, repeated measures and self-report data did not indicate consistent improvement in psychological flexibility during exposure phases. As any reduction in picking may be clinically meaningful and all participants maintained gains at follow-up, there is some indication that exposure may be a second-line treatment worth further study. Limitations and future areas of research are discussed.

Wearable devices provide a means of tracking hand position in relation to the head, but have mostly relied on wrist-worn inertial measurement unit sensors and proximity sensors, which are inadequate for identifying specific locations. This limits their utility for accurate and precise monitoring of behaviors or providing feedback to guide behaviors. A potential clinical application is monitoring body-focused repetitive behaviors (BFRBs), recurrent, injurious behaviors directed toward the body, such as nail biting and hair pulling, which are often misdiagnosed and undertreated. Here, we demonstrate that including thermal sensors achieves higher accuracy in position tracking when compared against inertial measurement unit and proximity sensor data alone. Our Tingle device distinguished between behaviors from six locations on the head across 39 adult participants, with high AUROC values (best was back of the head: median (1.0), median absolute deviation (0.0); worst was on the cheek: median (0.93), median absolute deviation (0.09)). This study presents preliminary evidence of the advantage of including thermal sensors for position tracking and the Tingle wearable device’s potential use in a wide variety of settings, including BFRB diagnosis and management.
