Assessment of distress in young children: a comparison of autistic disorder, developmental delay, and typical development.

Distress emotions in very young children are manifest in vocal, facial, and bodily cues. Moreover, children with different developmental conditions (i.e. autistic disorder, AD; developmental delay, DD; typically developing, TD) appear to manifest their distress emotions via different channels. To decompose channel of emotional distress display by group, we conducted a study in which video clips of crying of 18 children 18 months of age belonging to three groups (AD, DD, TD) were modified to isolate vocal, facial, or bodily cues, and 42 female adults were asked to judge the distress and typicality (expected normality) of the different stimuli. We find variation in adult judgements of distress and typicality by child group (AD, DD, TD) and by isolated cues (vocal, facial, or body). Although there is some overlap between responses to episodes of crying of children with AD and those with DD, the different cues of crying of children with AD tend to be considered more atypical and distressed than those of the other two groups (DD and TD). Early assessment of different cues of the expression of distress, and more generally of emotional expressivity in achild, may provide useful information for pediatricians and practitioners who are in contact with young children and must make clinical screening decisions. The findings also alert parents of children with AD to important aspects of their cries.
