A Meta-Analysis of Treatment for Self-Injurious Behavior in Children and Adolescents With Intellectual and Developmental Disabilities.
Parent-delivered behavioral plans slash self-injury just as well as clinic programs.
01Research in Context
What this study did
The team looked at every single-case SIB study published from 2011-2021.
They pulled multiple studies covering the children and teens with ID or DD.
Each study used behavioral treatment and measured SIB minute-by-minute.
What they found
SIB dropped a lot. The effect size was Tau-U = -0.90, which means almost all kids hurt themselves far less.
Good behaviors rose too, with Tau-U = 0.73.
Caregivers running the plan at home got the same big wins as clinicians in clinics.
How this fits with other research
Thillainathan et al. (literature) shows adults in a special ABA house also cut severe behavior. Their results stretch the same big gains past the teen years.
Older punishment tests like F et al. (literature) and C et al. (literature) found quick, near-zero SIB with tools like water mist or antecedent punishment. The new data say you can reach similar drops without those old aversives—just solid caregiver-led reinforcement plans.
M et al. (literature) found sensory integration doesn’t help challenging behavior. R et al. (literature) now give you something that clearly does: parent-run behavioral packages.
Why it matters
You no longer need to choose between clinic hours and progress. Train parents or staff at home, keep treatment integrity high, and expect the same sharp fall in SIB. Use brief caregiver coaching, telehealth check-ins, and simple data sheets so the plan keeps working after you leave.

03Original abstract
Self-injurious behavior (SIB) among children and youth with developmental disabilities has not diminished in prevalence despite the availability of effective interventions, and the impact on quality of life for people and their families is devastating. The current meta-analysis reviews SIB intervention research between 2011 and 2021 using single-case experimental designs with children and youth up to 21 years old and provides a quantitative synthesis of data from high-quality studies including moderator analyses to determine effects of participant and study characteristics on intervention outcomes. Encouraging findings include a high level of effectiveness across studies in the decrease of SIB (Tau-U = -0.90) and increase of positive behavior (Tau-U = 0.73), as well as an increase in studies (relative to prior reviews) reporting intervention fidelity, generalization, maintenance, and social validity. However, our findings shed limited light on potential moderating variables in the development of interventions for children and youth who exhibit SIB. Of the potential moderators of intervention effects, only implementer (researcher/therapist vs. parent/caregiver) and setting (clinic vs. home) were significantly associated with improved outcomes. We discuss the need for more robust involvement of natural communities of implementers in SIB intervention research to better equip them to effectively and sustainably meet the needs of people they care for. We also discuss the importance of creating systems enabling broad access for children with SIB to effective interventions in service of reducing burden for people, families, and society over time.
