Functional analysis of episodic self-injury correlated with recurrent otitis media.

The team watched one child with developmental delay. Every time the child got an ear infection, self-injury spiked.

They ran a short functional analysis. They tested if the infection made loud sounds painful, so escape from noise became extra powerful.

Self-injury only happened during ear-infection days. When the ears cleared, the behavior stopped.

The infection acted like a hidden switch. It turned escape from sound into strong reinforcement.

Allison et al. (1980) first showed escape can drive aggression. O'Reilly (1997) adds that a brief illness can suddenly flip the same escape switch for self-injury.

Rose et al. (2000) later stretched the idea into classrooms. They proved tiny task tweaks can calm escape behavior without removing the demand.

Matson et al. (2004) seemed to disagree. Their Rett cases kept high hand stereotypy no matter the setting. The gap is method: L et al. looked at automatic stereotypy, while O'Reilly (1997) tracked pain-triggered escape. Different behavior classes, different rules.

Next time you see a sudden burst of self-injury, ask the caregiver about ear pain, colds, or allergies. A quick doctor visit may remove the establishing operation faster than any behavior plan. Track health data on your daily sheet. When medical spikes line up with behavior spikes, treat the medical issue first, then teach an appropriate escape request.
