Stereotyped behaviors predicting self-injurious behavior in individuals with intellectual disabilities

Stereotyped behaviours as precursors of self‐injurious behaviours: a longitudinal study with infants and toddlers at risk for developmental delay

“…It implies that stereotyped behaviour was an influential variable in the development of SIB over time, which means that children who exhibited more frequent stereotyped behaviour in the earlier assessment tended to have more frequent SIB at a later assessment. Therefore, our results are consistent with the findings reported from the cross‐sectional study by Barnard‐Brak et al () despite considerable methodological differences. Their analysis was based on a much larger sample with a much broader age range than this study.…”

Potential Risk Factors for the Development of Self-Injurious Behavior among Infants at Risk for Autism Spectrum Disorder

“…This may be due to how highly correlated SIB and stereotyped behavior are or may indicate that specific topographies of stereotypy, versus stereotypy in general, are associated with SIB. For example, in a cross-sectional sample of 1871 children and adults with intellectual disabilities, Barnard-Brak et al (2015) found that stereotyped behavior was a strong predictor of SIB for 69% of participants but not for the remaining 31%. Their results also indicated that specific topographies of stereotypy (yelling and body rocking) may predict specific forms of SIB, versus a more general relationship between these classes of behavior.…”

“…Empirical studies addressing this model of SIB development are limited and findings overall have been mixed (Furniss and Biswas 2012). Causal relationship aside, there is evidence that motor stereotypy is associated with SIB (Barnard-Brak et al 2015; Oliver et al 2012; Petty et al 2009; Rojahn et al 2012) and may predict its occurrence (Barnard-Brak et al 2015; Richman et al 2012; Rojahn et al 2015). …”

Risk factors and topographies for self‐injurious behaviour in a sample of adults with intellectual developmental disorders

“…) and also to the fact that SIB prevalence is strongly influenced by several risk factors and their mutual complex interactions (Barnard‐Brak et al . ).…”

“…According to different studies, SIB prevalence figures fluctuate in the range between 4% and 19% in people with IDD (Oliver et al 1987;Emerson et al, 2001b;Cooper et al 2009;Bowring et al 2017), although some authors have estimated a prevalence of 82% for SIB in people with profound intellectual and multiple disabilities (Poppes et al 2010). These variations in prevalence estimates might be due to methodological differences between studies and to the criteria used to define SIB (Cooper et al 2009) and also to the fact that SIB prevalence is strongly influenced by several risk factors and their mutual complex interactions (Barnard-Brak et al 2015).…”
