Risk factors associated with self-injurious behaviors in children and adolescents with autism spectrum disorders.
Screen for odd sensory reactions and rigid sameness first; they are the clearest predictors of self-injury in autism.
01Research in Context
What this study did
Duerden et al. (2012) asked parents of 241 children with autism to fill out a survey. The survey looked at what might predict self-injury such as head-hitting or skin-picking.
They checked traits like sensory quirks, need for sameness, language level, and sleep issues. Then they ran stats to see which traits linked most strongly to SIB.
What they found
Two risk signs stood out above the rest: odd sensory responses and insistence on sameness. Kids who lined toys up or hated loud noise were more likely to hurt themselves.
Other factors like poor sleep or low talk showed weaker links. In short, sensory and sameness red flags gave the clearest SIB signal.
How this fits with other research
Granieri et al. (2020) looked at even younger kids with broad developmental delay. They also saw more SIB, but they stressed early age itself as the key driver. The two studies agree that SIB is common; G et al. narrow the focus to sensory and sameness within autism.
Shmaya et al. (2017) used sensory scores to predict meal-time problems, not self-injury. Their data show sensory issues ripple into many daily challenges, backing G et al.’s call to screen sensory profiles first.
Antezana et al. (2019) add a twist: girls with autism show more sameness and SIB than boys. This supports G et al.’s link and tells clinicians to weigh gender when judging risk.
Rooker et al. (2020) mapped injury severity to SIB function. They found automatically maintained SIB (often sensory based) causes the worst wounds. Their functional lens dovetails with G et al.’s sensory correlate and urges teams to watch sensory-driven SIB closely.
Why it matters
You can add two quick items to any intake: a sensory checklist and a sameness scale. If either score is high, plan deeper SIB assessment and start sensory-based prevention early. The move costs five minutes and may spare months of injury.

03Original abstract
While self-injurious behaviors (SIB) can cause significant morbidity for children with autism spectrum disorders (ASD), little is known about its associated risk factors. We assessed 7 factors that may influence self-injury in a large cohort of children with ASD: (a) atypical sensory processing; (b) impaired cognitive ability; (c) abnormal functional communication; (d) abnormal social functioning; (e) age; (f) the need for sameness; (g) rituals and compulsions. Half (52.3%, n = 126) of the children (n = 241, aged 2-19 years) demonstrated SIB. Abnormal sensory processing was the strongest single predictor of self-injury followed by sameness, impaired cognitive ability and social functioning. Since atypical sensory processing and sameness have a greater relative impact on SIB, treatment approaches that focus on these factors may be beneficial in reducing self-harm in children with ASD.
