Parents are the individuals who spend the most time with the child and are present across the widest range of contexts. SIB does not occur only during therapy sessions. For treatment to be effective, the people who are with the child throughout the day must be able to respond consistently and correctly. Additionally, young children with developmental delays may not yet be enrolled in intensive behavioral services, making parents the primary treatment agents. Parent training ensures that effective intervention occurs in the natural environment where the child lives and where the behavior is most likely to occur.
Functional assessment for very young children may need to be adapted from standard protocols. Brief functional analysis procedures, trial-based functional analysis conducted during natural routines, and descriptive assessment with conditional probability analysis are all options. Parent interviews provide valuable information about the contexts in which SIB occurs and the consequences that typically follow. Direct observation in the home environment captures naturalistic data. The goal is the same as with any functional assessment: to identify the maintaining contingencies so that intervention can be function-based.
Behavioral skills training (BST) is the gold standard for parent training. BST includes four components: instruction (explaining the procedure and its rationale), modeling (demonstrating the procedure), rehearsal (having the parent practice the procedure), and feedback (providing specific information about what the parent did correctly and what needs to change). For SIB management specifically, the rehearsal component is critical because parents need to build fluency in responding correctly during stressful situations. In-vivo coaching, where the clinician provides real-time guidance during actual parent-child interactions, further strengthens implementation.
When an intervention involves extinction, behavior analysts must explicitly prepare parents for the possibility of an extinction burst, a temporary increase in the frequency, duration, or intensity of the behavior. This preparation should include explaining what an extinction burst is and why it occurs, providing specific guidance on how to respond safely during a burst, establishing safety criteria for when to implement protective measures, and reassuring parents that the burst is a sign the intervention is working. Without this preparation, parents may interpret the burst as evidence that the treatment is failing and abandon it prematurely.
Parent stress significantly affects treatment outcomes. Parents who are highly stressed may have difficulty maintaining procedural fidelity, may be more likely to revert to ineffective strategies under pressure, and may be less available for training sessions. Stress can also affect the parent-child relationship in ways that influence the child's behavior. Behavior analysts should assess parent stress as part of the treatment planning process, provide strategies for self-management during challenging episodes, and refer parents to appropriate mental health support when stress levels interfere with treatment implementation.
Fidelity monitoring should include direct observation of parent implementation during scheduled sessions, review of parent-completed data sheets, and comparison of parent behavior to the written protocol. Fidelity data should be collected regularly, not just during initial training. Video recording of parent-child interactions (with appropriate consent) can supplement in-person observation and allow for more detailed feedback. When fidelity drops below acceptable levels, booster training sessions should be provided promptly to prevent erosion of treatment gains.
If the intervention is not reducing SIB, the behavior analyst should first evaluate implementation fidelity. If fidelity is low, additional training is needed. If fidelity is adequate but the behavior is not changing, the functional assessment should be re-examined. The maintaining contingencies may have been incorrectly identified, the function may have shifted, or there may be automatic reinforcement that was not initially detected. The intervention should be modified based on updated assessment data. Under Code 2.18 of the BACB Ethics Code (2022), behavior analysts are obligated to modify programs when data indicate desired outcomes are not being achieved.
Emerging research supports the feasibility of telehealth-delivered parent training for challenging behavior, including SIB. Telehealth can increase access for families in underserved areas and reduce barriers related to transportation and scheduling. However, telehealth delivery requires careful consideration of safety. The clinician cannot physically intervene during a dangerous episode and must ensure that the parent has the skills and resources to manage SIB safely without in-person support. A hybrid model that combines in-person sessions for initial training with telehealth for ongoing coaching may be optimal.
Any self-injurious behavior that occurs regularly, causes or risks tissue damage, or is increasing in frequency or intensity warrants professional assessment. Parents and pediatricians sometimes adopt a wait-and-see approach, but the evidence supports early intervention. SIB that is not addressed early can escalate and become more resistant to treatment. Behavior analysts should advocate for early referral and should communicate to referral sources that early assessment and intervention for SIB can prevent the development of chronic, treatment-resistant patterns.
Early SIB in young children may be less firmly established in the behavioral repertoire, maintained by simpler reinforcement contingencies, and more responsive to intervention. Treatment for established SIB in older individuals often requires more intensive and complex intervention packages, may involve managing years of reinforcement history, and may need to address physical changes (such as calluses) that provide automatic reinforcement. Early intervention also benefits from the greater neuroplasticity of young children and the opportunity to establish effective caregiver response patterns before maladaptive patterns become entrenched.
