Relationship Between Sensory Processing and Autism Spectrum Disorder-Like Behaviors in Prader-Willi Syndrome.

This study looked at 51 adults with Prader-Willi Syndrome to see if sensory difficulties (like being over- or under-sensitive to sounds, textures, etc.) were connected to autism-like behaviors. They found that people with more sensory challenges also showed more autism-like behaviors and other difficult behaviors. This suggests that understanding and addressing sensory needs might help with behavior support.

This cross-sectional study examined the relationship between sensory processing difficulties and autism spectrum disorder-like behaviors in 51 adults with Prader-Willi Syndrome. Participants were assessed using standardized measures including the Short Sensory Profile and autism rating scales. Based on sensory processing severity, participants were grouped into three categories. Results showed statistically significant differences between groups, with those experiencing more severe sensory processing difficulties demonstrating higher levels of ASD-like behaviors and aberrant behaviors.

The findings suggest sensory processing levels may predict behavioral presentations in adults with PWS, highlighting the potential importance of sensory assessment for early intervention planning.

Findings suggest clinicians should routinely assess sensory processing in adults with PWS presenting with ASD-like or challenging behaviors. Sensory-based interventions may be beneficial as part of comprehensive behavior support plans. Early identification of sensory difficulties could inform intervention strategies and potentially prevent escalation of behavioral challenges.

Single cross-sectional study with modest sample size (n=51). Study type not specified in metadata. Limited to adults with PWS, so generalizability to other populations unclear. Cross-sectional design cannot establish causation between sensory processing and behaviors.

The relationship between sensory processing and ASD-like and associated behaviors in patients with Prader-Willi Syndrome (PWS) remains relatively unexplored. Examining this relationship, 51 adults with PWS were administered the Pervasive Developmental Disorders Autism Society Japan Rating Scale (PARS), Short Sensory Profile (SSP-J), Food-Related Problem Questionnaire (FRPQ), and Aberrant Behavior Checklist (ABC-J). Based on SSP-J z-scores, participants were classified into three severity groups. Analysis of variance was performed to compare the behavioral scores of these three groups.

Statistically significant group differences were observed in PARS (p = .006, ηp2 = .194) and ABC-J (p = .006, ηp2 = .193) scores. Our findings suggest that the level of sensory processing may predict ASD-like and aberrant behaviors in adults with PWS, implying the importance of a proper assessment for early intervention.
