Self-injurious behaviour in individuals with intellectual disabilities

Area of Science:

• Intellectual Disabilities Research
• Behavioral Science
• Pharmacology

Background:

• Self-injurious behavior (SIB) is a significant concern in individuals with intellectual disabilities (ID).
• Understanding the underlying causes and effective treatments for SIB is crucial for improving quality of life.

Purpose of the Study:

• To review the 2004 literature on self-injurious behavior in individuals with intellectual disabilities.
• To examine phenomenology, comorbidity, interventions, genetic syndromes, and behavioral assessment and treatment.

Main Methods:

• Literature review of studies published in 2004.
• Synthesis of findings across different research domains including behavioral analysis, genetics, and pharmacology.

Main Results:

• A potential association between self-injury, impulse control, and stereotyped behaviors was identified.
• Pharmacological interventions, including naltrexone, showed limited evidence of efficacy for SIB.
• Predictors of SIB in Prader-Willi syndrome are becoming clearer, and assessment methodologies are advancing.

Conclusions:

• Applied behavior analysis and genetic syndrome research emphasize the need for individualized assessments and interventions for SIB.
• Despite widespread prescription, robust evidence for the efficacy of pharmacological interventions for SIB remains weak.
