In vivo desensitization in the management of self-injurious behavior
Summary
In vivo desensitization successfully managed self-injurious face slapping in a child. This behavioral intervention eliminated harmful actions and promoted self-control, leading to the discontinuation of protective equipment.
Area of Science:
- Behavioral Psychology
- Developmental Disabilities
Background:
- Self-injurious behavior (SIB) management in children with developmental disabilities presents significant challenges.
- Face slapping, a form of SIB, escalated in a 10-year-old boy following dental surgery, necessitating protective measures like a hockey helmet.
Observation:
- The child's attempts to remove the helmet intensified agitation and SIB.
- The child also exhibited self-restraint behaviors, seeking to replace the helmet or prompt adult intervention.
- A hierarchy of situations was established for introducing desensitization without the helmet.
Findings:
- An in vivo desensitization procedure, implemented by parents across various home situations, effectively eliminated face slapping.
- A multiple baseline design monitored progress, showing sustained improvement over 6, 9, 12, and 15 months.
- The child developed self-control, wearing the helmet when agitated and removing it when relaxed, eventually discontinuing its use.
Implications:
- In vivo desensitization is a viable and effective treatment for managing SIB in children with developmental disabilities.
- Parental involvement in implementing behavioral interventions can lead to successful outcomes and improved self-regulation.
- This case highlights the potential for gradual exposure and behavioral modification to overcome severe self-injurious behaviors.
