Functional Assessment and Behavioral Treatment of Skin Picking in a Teenage Girl With Prader-Willi Syndrome

Abstract

Skin picking is common in individuals with Prader-Willi Syndrome (PWS) but few treatment studies exist. This study reports the successful functional behavioral assessment (FBA) and treatment of skin picking in a 16-year-old female with PWS. A treatment package based on FBA results consisted of differential reinforcement for alternative and incompatible behavior, selfevaluation of progress, and reinforcement for weekly progress and participation in treatment. Pictures of wounds resulting from skin picking were taken during treatment. A total of 30 pictures were randomly selected and shown in a random order to 16 individuals unfamiliar with the study. The individuals then rated severity of the wounds displayed in the pictures. Pearson's c 2 was used to assess changes in the ratings of severity during the course of treatment, and significant results indicate improvement over the course of intervention, c 2 (1) = 246.6, p < .001. This study adds to the very small literature on treatment of skin picking in people with PWS.

Behavioural phenotypes and special educational needs: is aetiology important in the classroom?

“…In Prader–Willi syndrome, two case studies have been published of interventions for reducing the occurrence of skin‐picking a common problematic behaviour in the syndrome. Radstaake et al . (2011) reported on the successful use of functional behavioural assessment and treatment of skin picking in a 16‐year‐old female with the syndrome.…”

Radstaake et al (2011) reported on the successful use of functional behavioural assessment and treatment of skin picking in a 16-year-old female with the syndrome. Stokes & Luiselli (2009) describe a study where the skin picking of a 26-year-old male with Prader-Willi was reduced by restricting the individual's access to the setting in which skin picking most often occurred (i.e.…”

Rehabilitación neuropsicológica en personas con síndrome de Prader-Willi

“…Las características fenotípicas intervenidas fueron lenguaje (Bellon-Harn, 2005; Misquiatti, Cristovão y Brito, 2011), habilidades adaptativas (Dolyniuk et al, 2002; Gardner y Wolfe, 2015), hiperfagia (Grolla et al, 2011;Messersmith, Slifer, Pulbrook-Vetter y Bellipanni, 2008;Rose y Walker, 2000;Singh et al, 2008;Singh et al, 2011), robo de comida (Maglieri, DeLeon, Rodriguez-Catter y Sevin, 2000), conducta social (Samuels y Stansfield, 2012), pataletas (Messersmith et al, 2008;Rose y Walker, 2000), rascado de piel (Radstaake et al, 2011), rascado rectal (Stokes y Luiselli, 2009) y síntomas obsesivos-compulsivos (Storch et al, 2011).…”

“…En cuanto a las fases, además de la intervención, seis estudios explicitaron una fase de línea base (Rose y Walker, 2000; Stokes y Luiselli, 2009), un estudio explicitó una fase de seguimiento (Messersmith et al, 2008), cuatro estudios explicitaron tanto fase de línea base como de seguimiento (Gardner y Wolfe, 2015;Samuels y Stansfield, 2012;Singh et al, 2008;Singh et al, 2011) y siete estudios no explicitaron ninguna de las dos (Bellon-Harn, 2005;Dolyniuk et al, 2002;Grolla et al, 2011;Maglieri et al, 2000;Misquiatti et al, 2011;Radstaake et al, 2011;Storch et al, 2011).…”

“…El 43% de los estudios utilizaron intervenciones de corte puramente conductual y el resto fueron logopédicas, vocacionales, mindfulness y cognitivo-conductual. La mayoría de las intervenciones se realizaron en algún centro, hospital o institución clínica, con excepción de cinco estudios que se realizaron en casa de los sujetos, parcialmente en pisos tutelados o en la escuela (Dolyniuk et al, 2002;Gardner y Wolfe, 2015;Radstaake et al, 2011;Singh et al, 2008;Singh et al, 2011).…”
