Regulatory disorder consists of two components: (1) the sensory component and (2) specific behavioral pattern. Four different types of regulatory disorders have been identified: (1) Hypersensitive, (2) Under - reactive, (3) Disorganized and (4) Other.

The present research was designed to systematically examine the epidemiology of regulatory disorders among Israeli children and their association to different factors (developmental patterns, age, sex, ethnic origin).

The study population included 450 participants aged 6 - 36 months, whos parents completed a questionnaire based on the existing regulatory disorders literature. In addition, information pertaining to demographic data, child's medical history, develpmental progress and growth, was collected.

Factor analysis was employed to delineate factors representing different types of regulatory disorders. Six new factors were created for the 6 - 17 months' age group and nine new factors were created for the 18-36 months' age group.

The derived factors are different from the four types described in the literature. Furthermore, the numbers as well as types of regulatory disorders are different between the two age groups. The prevalence of regulatory disorders in the study population was found to be 18.9% at the younger age group and 17.9% for the older age group.

A significant association was found between regulatory disorders and gross motor difficulty. There was no significant association between regulatory disorders and fine motor, language and social development. In general, no significant association was found between regulatory disorders and ethnic origin.

The results of this study point to the diversity of regulatory disorders among young children. The prevalence of regulatory disorders in our non-clinical population calls for attention. It is conceivable that a proportion of the children experience difficulties which can be relieved by a well-attuned parent.
