Problems addressed in this book include developmental delay in low birth weight infants and socially disadvantaged children, adjustment problems in children with sensory and additional disabilities and autism, challenging behaviour in children with intellectual disabilities, physical and sexual abuse, bullying, adjustment problems in children with asthma and diabetes, teenage smoking, alcohol use and drug abuse, teenage pregnancy, STDs and HIV infection, post-traumatic adjustment problems and adolescent suicide. Conclusions drawn in this book are based on the results of over 200 rigorously conducted studies of more than 70, 000 children.
