Exploring the Heterogeneity of Self-Injurious Behaviors in Autistic Youth: Patterns, Predictors, and Implications for Intervention.

Ferguson et al. (2025) asked caregivers to rate five common self-injurious behaviors in autistic youth. The list: biting, scratching, head-hitting, head-banging, and skin-picking.

The team then looked at how each behavior tied to child traits like age, sex, IQ, language level, dysregulation, and sensory hypersensitivity.

Each SIB form had its own risk profile. For example, one behavior might spike with high sensory scores while another tracked with low language.

No single child trait predicted all topographies. Severity varied widely across kids.

Capio et al. (2013) first showed that impulsivity and stereotypy forecast SIB in autism. Ferguson et al. (2025) extend that idea by splitting SIB into separate topographies and linking each to different traits.

Faso et al. (2016) found early stereotypy in toddlers later turns into SIB. The new data say once SIB shows up it keeps splitting into distinct forms, so catch stereotypy early then still assess which SIB you face.

van der Miesen et al. (2024) meta-analysis proves SIB treatments work best when matched to the child. F et al. give you the map: assess topography first, then pick the intervention that fits that profile.

Hatzell et al. (2026) show sleep problems double SIB odds. F et al. add sensory hypersensitivity as a second, separate driver. Screen for both sleep and sensory issues; either can push a specific SIB.

Stop treating SIB as one behavior. When you see head-banging, check for sensory pain. When you see skin-picking, look at language level. Tailor your functional assessment and your intervention to the topography you observe. This quick shift can shorten assessment time and get you to effective treatment faster.
