Assessment & Research

Phenomenological characteristics, social problems, and the economic impact associated with chronic skin picking.

★ The Verdict

Experiential avoidance partly explains why skin-picking severity and emotional distress stick together—assess and treat the avoidance, not just the picking.

✓ Read this if BCBAs who treat body-focused repetitive behaviors or co-occurring anxiety in adult outpatient clinics.
✗ Skip if Practitioners working solely with early-childhood autism or skill-acquisition cases where skin picking is absent.

01Research in Context

01

What this study did

Researchers sent an online survey to 92 adults who said they pick their skin. The survey asked how often and how hard they pick, how sad or nervous they feel, and how much they try to avoid upsetting thoughts.

They wanted to see if ‘experiential avoidance’ helps explain why skin picking and emotional pain often show up together.

02

What they found

The worse the picking, the higher the scores for depression and anxiety. Experiential avoidance sat in the middle: it partly carried the link between picking severity and emotional distress.

In plain words, people who work hard to push away uncomfortable thoughts and feelings report both more picking and more mood trouble.

03

How this fits with other research

Casanova (2023) tested an ACT-based exposure add-on to habit reversal. HRT cut picking the most, but the ACT piece gave a small extra gain. That trial builds on the 2006 survey: if avoidance is a key driver, then ACT moves that fit perfectly.

Richman (2008) argues that avoidance turns ordinary sadness into clinical depression. The skin-picker data line up: avoidance scores partly explain why picking and mood symptoms travel together.

Sairanen et al. (2015) show that psychological flexibility helps overweight adults eat intuitively. The same flexibility construct (low avoidance) predicts better mental health across very different body-focused habits.

04

Why it matters

During intake, add a brief measure of experiential avoidance (e.g., AAQ-II). A high score signals that standard sensory or habit blocks may not be enough. You can weave in values work, mindfulness, or ACT-based exposure to target the avoidance itself, not just the picking topography.

03Original abstract

In this study, the authors collected data on the demographic characteristics, phenomenology, and social and economic impact of skin picking. A total of 92 participants completed an anonymous, Internet-based survey through a link to the Trichotillomania Learning Center's home page. Results indicated that skin pickers experienced social, occupational, and academic impairment, a number of medical or mental health concerns, and financial burdens, which they attributed to skin picking. Results also revealed moderate, statistically significant relationships between skin picking severity and symptoms of depression, anxiety, and experiential avoidance. Subsequent mediational analyses demonstrated that the relationship between skin picking severity and symptoms of anxiety and depression was partially mediated by experiential avoidance. Implications, conclusions, and future areas of research are discussed.
