Highly sensitive children show more emotional difficulties but fewer behaviour risks, Egyptian study finds

A study of 391 children in Egypt links high sensory processing sensitivity with greater emotional difficulties, while also finding lower rates of hyperactivity and weak prosocial behaviour.

Some children seem to experience the world more intensely than others, and a new study from Egypt suggests that this sensitivity may carry both costs and strengths. Research published in BMC Pediatrics found that about one in 10 children in the sample met the threshold for high sensory processing sensitivity, a temperament trait rather than a disorder, and that these children were much more likely to show emotional difficulties than their less sensitive peers.

The study, led by researchers at Alexandria University with partners from Egyptian health institutions and the London School of Hygiene and Tropical Medicine, looked at 391 parents of children aged four to 17. According to the paper, parents completed standard screening tools for emotional and behavioural concerns as well as a questionnaire designed to measure sensory processing sensitivity. The researchers reported that 10.2% of the children were classified as highly sensitive, a figure that sits within the range often cited in the wider literature on the trait.

The findings were strongest for emotional problems. The study found that 82.5% of highly sensitive children scored in the at-risk or elevated range on that measure, compared with 66.7% of children who were not highly sensitive. The authors said the difference was statistically significant, supporting the idea that children who process sensory and social input more deeply may also be more exposed to worry, fearfulness and low mood. PubMed and PubMed Central summaries of the paper report the same overall pattern.

But the study also points to a less familiar side of sensitivity. Highly sensitive children were less likely to score in the at-risk range for hyperactivity, and they were also less likely to show weak prosocial behaviour, meaning behaviour that reflects kindness, cooperation and helpfulness. That finding fits with earlier research suggesting that sensory processing patterns can be linked not only to internalising problems such as anxiety and depression, but also to the way children relate to others and regulate their behaviour.

The authors caution that the study cannot show whether sensitivity causes emotional problems, only that the two occur together in this sample. Because the research was cross-sectional and based on parent reports, it cannot capture how children themselves experience their environment, and it cannot rule out the influence of factors such as parenting, schooling or wider family stress. Even so, the study adds a useful data point for Egypt, where evidence on sensory processing sensitivity in children has been limited, and it suggests that caregivers and teachers may need to look beyond disruptive behaviour to spot children who are struggling quietly.
