Skin Picking in People with Prader-Willi Syndrome: Phenomenology and Management.
Skin picking in Prader-Willi syndrome zeroes in on imperfect skin and parents still rely on simple distraction—time for data-driven behavior plans.
01Research in Context
What this study did
The team talked to the adults with Prader-Willi syndrome and their parents.
They asked where, when, and why the person picks their skin.
No one tried a new treatment; they just wrote down what was already happening.
What they found
Most people picked at scabs, dry skin, or tiny bumps.
Parents said they mainly stop it by calling the person away or handing them a toy.
No one tracked if the picking got better or worse.
How this fits with other research
Ahrens et al. (2011) watched stereotypy in autism and saw it stop on its own.
That study hints we should first see if skin picking in PWS also ends without help.
Ventola et al. (2016) gave kids PRT and their repetitive behaviors dropped.
Their result says a real intervention can work, but parents in Adams et al. (2021) still rely on quick distraction.
The gap shows we need a tested plan beyond "here, play with this."
Why it matters
You now know skin picking in PWS is not random—it aims at flawed skin.
Start by mapping each client’s favorite spots and triggers.
Then run a short baseline to see if it self-stops like the autism stereotypy work suggests.
If not, craft a tiny intervention—maybe differential reinforcement or response blocking—and take data.
You will move families from guess-work to evidence.

03Original abstract
Skin picking is highly prevalent in people with Prader-Willi syndrome (PWS). This study addressed the temporal (frequency, duration) and wider characteristics (e.g. type of skin picked, apparent motivations, or management strategies) of skin picking to inform intervention strategies. Nineteen parents/carers who observe skin picking shown by the person they care for completed a semi-structured interview. Results were consistent with previous research but advanced the field by finding that most participants picked skin with an imperfection and that parents/carers most commonly use distraction as a management strategy. Interventions that are behavioural, support emotion regulation and/ or are used in the typically developing population are therefore likely to be beneficial for future research.
