Self-injurious behaviour in people with intellectual disability

Area of Science:

• Psychiatry
• Developmental Psychology
• Behavioral Science

Background:

• Self-injurious behavior (SIB) is a significant concern in individuals with intellectual disability (ID) and autism spectrum disorders (ASD).
• Understanding the multifaceted nature of SIB is crucial for developing effective interventions.
• Existing research spans various domains, including prevalence, risk factors, and treatment modalities.

Purpose of the Study:

• To critically evaluate peer-reviewed studies on self-injurious behavior in individuals with intellectual disability and autism spectrum disorders.
• To synthesize current knowledge on the prevalence, characteristics, and influencing factors of SIB.
• To review the efficacy of various assessment and intervention strategies.

Main Methods:

• Comprehensive literature review of peer-reviewed publications.
• Analysis of studies focusing on prevalence, risk markers, and individual characteristics.
• Evaluation of research on biological, psychological, and behavioral influences.
• Assessment of psychological and pharmacological interventions and their efficacy.

Main Results:

• Prevalence data identifies characteristics associated with SIB persistence and presence, serving as potential risk markers.
• Research highlights the efficacy of behavioral interventions through meta-analyses and improved assessment procedures.
• Studies indicate the effectiveness of pharmacological interventions like aripiprazole and combined parent training with risperidone.
• A link between pain behavior and SIB is suggested, with implications for endorphin involvement.

Conclusions:

• SIB in ID and ASD is influenced by a complex interplay of factors, necessitating a holistic approach.
• Systematic evaluations support the efficacy of both behavioral and pharmacological interventions.
• Identifying individual characteristics and risk markers is vital for targeted assessment and intervention.
• Future research should continue to explore the multiple influences on SIB to refine treatment strategies.
