This book comes when there is great activity in the field of mental retardation and when a study such as this is immediately pertinent. As the sample for his study, Dr. Ehlers selected 24 mothers from the files of the Cambridge Service for Retarded Children, a public health clinic in Cambridge, Massachusetts. The author not only explored the mothers' feelings and attitudes about their child's retardation and how and why they sought help, but he examined the functions of the clinic and its eight workers.
