Self-injurious behavior

Urgent safety: In the United States, the SAMHSA crisis-help page directs anyone in danger or having a medical emergency to call 911 or go to the nearest emergency room. Use local emergency systems elsewhere.

Define what happened in observable terms

The label SIB covers very different events. Describe the action, body area, intensity, duration, setting, and observable injury. Record the opportunity or observation time so a count has context. “Three strikes to the side of the head during a 20-minute bus ride” is more useful than “had severe SIB.”

Separate forms that create different risks. Skin picking, head impact, eye pressing, ingestion, and self-biting may need different medical expertise, protective steps, and measurement.

Address injury and possible medical causes

New, sudden, escalating, or unusual self-injury can accompany pain, infection, headache, dental problems, sleep loss, seizures, medication effects, vision or hearing changes, gastrointestinal concerns, or another health condition. Seek appropriate medical evaluation rather than assigning a behavioral explanation first.

Document injury, consciousness changes, breathing, bleeding, swelling, possible ingestion, and other warning signs accurately. A clinician qualified for the relevant health question decides the medical response.

Assessment asks what conditions matter

The BACB BCBA Test Content Outline covers descriptive assessment, functional analysis, cultural variables, medical referral, and function-based intervention as professional examination content. It does not authorize a particular method for one person.

A qualified behavior analyst may review records, interview the person and caregivers, observe defined situations, and compare patterns across conditions. Any experimental analysis involving dangerous behavior needs specialist competence, risk controls, informed consent, assent when applicable, stopping rules, and appropriate setting support.

Communication belongs in every safety plan

Ask what the person is communicating before, during, and after an event. Pain, stop, break, help, finished, more, and leave should be available through speech, sign, gesture, writing, movement, or augmentative and alternative communication (AAC).

The ASHA AAC portal says AAC users should always have access to their tools or devices. Partners should know the person’s reliable messages, backup method, access position, and needed wait time.

Prevention starts with the surrounding system

Useful prevention may include medical treatment, reliable communication, predictable transitions, reduced noise or crowding, choice, adjusted demands, safe access to preferred activities, trained partners, sleep support, and removal of environmental hazards. The right combination depends on the assessed variables and the person’s priorities.

Protect food, water, bathroom use, mobility, communication, prescribed care, and emergency help. A safety plan should define what partners do early, who leads escalation, and when an activity stops.

Restrictive procedures require separate authority

Physical restraint, protective equipment, response blocking, emergency medication, and other restrictive responses have different meanings and rules. A SIB label or risk score never supplies permission by itself.

The current BACB Ethics Code addresses competence, medical referral, client involvement, consent and assent when applicable, risk, least-intrusive effective procedures, data, and continual evaluation for covered behavior analysts. Applicable law, setting policy, licensure, and other professional duties still govern.

A fictional transit example

Noemi is a fictional teenager who begins striking the side of her head during van transitions. Across ten observed transitions, the defined response occurs in 1 of 10. During a week with a new route and an untreated ear infection, it occurs in 7 of 12 transitions.

The family obtains medical care, the clinic pauses the noisy route, and Noemi receives an accessible stop message. These combined changes prevent a claim that one variable caused the pattern. The team records injury, route, noise, health status, communication access, adult response, and transition outcome for each opportunity.

Questions families can ask

Ask who evaluates injury and medical concerns, who holds severe-behavior competence, and how the person communicates pain, stop, and help. Request observable definitions, ordinary supports, emergency thresholds, and reassessment triggers.

Ask how assent or withdrawal is recognized, how data exclusions are reported, and how partners learn the plan. Clarify which events require medical care, incident reporting, clinical review, or another specialist.

Track recovery as well as events

Event counts show only part of the burden. Record injury recovery, interrupted activities, medical visits, sleep effects, missed school or work, and the person’s report. These outcomes may reveal meaningful improvement before event frequency changes.

Use the same observation window when comparing periods. Report setting changes, health changes, new supports, and missing observations beside the result. Small samples deserve raw counts, since a percentage can swing sharply after one additional event.
