Repetitive and restricted behaviours and anxiety in autism spectrum disorder: protocol for a systematic review and meta-analysis

Abstract Background Autism spectrum disorder (ASD) is a neurodevelopmental disorder defined by persistent deficits in social functioning and the presence of restricted and repetitive behaviours (RRBs). RRBs refer to four subtypes of behaviour including repetitive movements, speech, or use of objects...

RRBs refer to four subtypes of behaviour including repetitive movements, speech, or use of objects; insistence on sameness; restricted interests; and sensory processing abnormalities. Many individuals with ASD also experience anxiety, which compounds ASD-related difficulties and inhibits daily functioning.

Articles included in the review will have their titles, abstracts, and full texts reviewed by two independent authors and their methodological quality assessed via the modified Newcastle-Ottawa Scale. Random-effects meta-analyses will then be conducted to calculate the pooled association between RRB subtypes and anxiety.

Discussion This will be the first review to examine the association between the four subtypes of RRBs and anxiety in individuals with ASD. Understanding this relationship, and the factors associated with this, may help clinicians understand the different underpinnings and presentations of anxiety within this population with potential implications for assessment and treatment.
