Development of a brief version of the Autism Detection in Early Childhood.

While autism spectrum disorder screening tools provide a useful resource for practitioners, the reality is they are underused. The justifications often provided include the time required for administration and the training involved. A brief tool with good psychometric properties that require minimal training is required. This study examined the development and the psychometric properties of a brief version of the Autism Detection in Early Childhood. The data showed the potential of the brief version of Autism Detection in Early Childhood for screening children age 12-36 months. Our dataset comprised 106 Diagnostic and Statistical Manual of Mental Disorders, 5th edition autism spectrum disorder, 86 non-typical development and 78 typical development participants age 12-36 months. Analyses comparing autism spectrum disorder and non-typical development groups supported the use of five critical items (i.e. response to name, social smiling, gaze switch, response to verbal command and use of gestures) to form the brief version Autism Detection in Early Childhood. The brief version of Autism Detection in Early Childhood's optimal cutoff score of 4 had sensitivity of 0.81, specificity of 0.78, positive predictive value of 0.81 and negative predictive value of 0.78. However, the results would need to be viewed as preliminary given the nature of the study sample and the findings might not be generalisable to samples with higher levels of cognitive functioning.
