"The DC:0-3 Casebook" complements DC:0-3 by helping professionals from all disciplines put DC:0-3's diagnostic system into practice. Twenty-four detailed case reports, documenting work with children (ages 6 months to 4-1/2 years) and their families, show how highly experienced practitioners from a range of disciplines use Zero to Three's DC:0-3. Settings for these cases include infant mental health clinics, paediatric primary care settings, early intervention programs, private multidisciplinary practices, consultation to child care and education settings, and the child welfare system. Each case study illustrates a different DC: 0-3 diagnostic category, taking readers step-by-step through the process of referral, assessment, diagnosis, discussion of the diagnosis and treatment planning with the child's family and caregivers, intervention, prognosis, and discussion and reflection.
