ABA for Self-Injurious Behavior (SIB)

Self-injurious behavior — head-banging, self-hitting, or self-biting — is frightening to witness and a top safety priority. ABA is one of the most effective approaches for understanding why it happens and reducing it safely.

Why self-injury happens

Self-injurious behavior (SIB) can serve different purposes: escaping a demand or overwhelming situation, gaining a response, meeting a sensory need, or sometimes signaling pain or a medical issue. Because SIB can have medical causes (such as headaches, ear infections, or dental pain), it should always be reviewed by a physician first. A BCBA then conducts a functional assessment to identify the specific drivers for your child.

Reducing SIB safely

Once the function is understood, ABA teaches safer replacement behaviors that meet the same need — for example, asking for a break or for help instead of self-hitting — while adjusting the environment to prevent triggers and prioritizing safety throughout. Plans use positive, non-punitive strategies and are tracked closely with data. Related: challenging behavior and the FBA.
