What should parents do if their kids are among the one in six 6-to-17-year-olds diagnosed with a mental disorder? In this reassuring guide, clinical social worker Corcoran, a professor at the University of Pennsylvania School of Social Policy and Practice, gives easy-to-understand advice. Dismiss debunked ideas like blaming “refrigerator mothers” for autism or thinking of homosexuality as a problem. A mind-boggling nine percent of 4-to-17-year-olds in the U.S. have been diagnosed with attention deficit hyperactivity disorder. This condition can affect the whole family: parents of a child with ADHD are more likely to be divorced. Like adults, kids can suffer from social anxiety and obsessive-compulsive disorder. OCD behavior like skin-picking, hair-pulling, and arranging items in specific ways can be a means of assuaging anxiety. Corcoran explains cognitive-behavioral therapy and “orthorexia nervosa,” an obsession with a fit and healthy lifestyle that’s not yet in the Diagnostic and Statistical Manual of Mental Disorders. Among the discipline tips she offers are focus on consequences (if a child destroys something, don’t replace it) and offer choices; they’re better than a flat “no.” A genuinely helpful handbook.
