'... there is little to fault in this scholarly treatise which thoroughly addresses the diagnostic issues of preschool children with impaired communication and provides a jumping-off point, both for future research endeavors and for more accurate diagnosis of impaired communication in preschool children by all professionals involved in their care.' Julia M. Robertson, Journal of the American Academy of Child and Adolescent Psychiatry 'While the monograph raised some very interesting aetiological questions and discussions regarding proposed classificatory systems, it was for the wealth of informative clinical detail and potential this may have for making one's assessments and therapeutic interventions that I found this text most valuable.' Marian Perkins, Archives of Disease in Childhood '... the authors have done an excellent job of presenting the results from a complex project, providing cogent summaries of the findings in each area of analysis, and interpreting the implications of the findings for clinical evaluation and intervention.' Linda R. Watson, Physical and Occupational Therapy in Pediatrics '... highly recommended for all academic professionals involved in evaluation of children with delayed or deviant communication. It is 'a must' for clinical researchers in the field. I think it will prove to be one of the highlights in the 'red series'.' Peder Rasmussen, European Child and Adolescent Psychiatry '... provides a wealth of information to guide evaluation and proper diagnosis.' Journal of Pediatric Nursing
