High frequency of sensory processing dysfunctions (SPD) is prevalent among children with intellectual developmental disabilities and contributes to their maladaptive behaviors. However, the knowledge about the expressions of SPD in different levels of IDD severity is limited. As SPD may reduce adaptive responses and limit participation, this knowledge should be elaborated. The purpose of the present study was to examine the specific expressions of sensory processing among children with different severity levels of IDD. Participants were 91 children aged 4-9 years with mild, moderate severe-profound and IDD. Their parents completed the short sensory profile (SSP). According the results, SPD were manifested across all levels of IDD. Groups differed in specific behaviors related to sensory stimuli. The highest percentage of children with severe sensory processing difficulties was found among children with mild and sever IDD level. SPD may characterize children with all severity levels of IDD. Nevertheless, the probability that children with a specific IDD level will be more vulnerable to specific aspects of SPD emphasizes the need for early evaluation and intervention to address the specific sensory needs of children with different IDD levels. This may enhance their development, performance and participation in daily living.
