Insights
Restricted and repetitive behaviors (RRBs) in children can signal later emotional and behavioral difficulties. Insistence on sameness (IS) at age six links to internalizing issues, while repetitive sensory-motor (RSM) behaviors at age six link to externalizing issues.
Area of Science:
- Child psychology
- Developmental neuroscience
- Behavioral science
Background:
- Restricted and repetitive behaviors (RRBs) are crucial for development but elevated levels beyond early childhood are linked to poorer outcomes.
- RRBs are observed across various neurodevelopmental conditions and can impact language, cognition, and wellbeing.
- Understanding distinct RRB subtypes and their developmental trajectories is key to identifying associated difficulties.
Purpose of the Study:
- To investigate the association between distinct RRB subtypes (insistence on sameness and repetitive sensory-motor behaviors) and internalizing/externalizing difficulties.
- To examine how these associations differ at ages two and six years.
- To explore the developmental course of RRBs and their predictive value for emotional and behavioral problems in children.
Main Methods:
- Utilized data from 485 parents reporting on their child's insistence on sameness (IS) and repetitive sensory and motor (RSM) RRBs using the Repetitive Behaviour Questionnaire (RBQ-2) at ages two and six.
- Assessed emotional and behavioral difficulties using the Strengths and Difficulties Questionnaire (SDQ) at age six.
- Analyzed the associations between RRB subtypes at different ages and emotional/behavioral outcomes.
Main Results:
- RRBs measured later in development (age six) were stronger predictors of emotional and behavioral difficulties than those measured earlier (age two).
- Insistence on sameness (IS) RRBs at age six were specifically associated with internalizing behaviors.
- Repetitive sensory-motor (RSM) RRBs at age six correlated with externalizing behaviors, whereas RSM RRBs at age two showed an association with fewer externalizing behaviors, supporting their adaptive role in early development.
Conclusions:
- Elevated RRBs, particularly specific subtypes at certain developmental stages, can serve as indicators for emotional and behavioral difficulties at age six.
- Findings highlight the differential impact of IS and RSM RRBs on internalizing and externalizing behaviors, respectively.
- Further research is needed to fully delineate the adaptive periods for IS and RSM RRBs, but current findings suggest their utility in identifying children at risk for behavioral issues.
Background:
Restricted and repetitive patterns of behaviour (RRBs) serve an adaptive role in development. Elevated levels of RRBs beyond the early years, however, are associated with poorer outcome in language, cognition, and wellbeing, and are seen across a range of neurodevelopmental conditions. This study aimed to characterize the association of distinct RRB subtypes at two and six years of age, with internalising and externalising difficulties in a community sample of children.
Methods:
485 parents reported on their child's insistence on sameness (IS) and repetitive sensory and motor (RSM) RRBs at two and six years of age using the Repetitive Behaviour Questionnaire (RBQ-2). Emotional and behavioural difficulties were measured using the Strengths and Difficulties Questionnaire (SDQ) at age six.
Results:
Consistent with previous research, RRBs later in development better predicted emotional and behavioural difficulties at age six than RRBs earlier in development. Moreover, IS RRBs were selectively associated with internalising behaviours and RSM RRBs with externalising behaviours. Importantly, these selective associations depended on when RRBs were measured. Only IS RRBs at age six were significantly associated with internalising behaviour. By contrast, while more RSM RRBs at age six were associated with higher rates of externalising behaviours, higher rates of RSM RRBs at age two were associated with fewer externalising behaviours, adding further support to the previously reported adaptive role of RRBs in early behaviour regulation.
Conclusion:
Although there is a need for further research to provide a detailed profile of the adaptive periods for IS and RSM RRBs, the present findings support the potential utility of elevated RRBs as a signal for emotional and behavioural difficulties at age six.
