“Adolescence strikes fear in the hearts of even the best parents,” writes journalist Maia Szalavitz in her new book Help at Any Cost: How the Troubled-Teen Industry Cons Parents and Hurts Kids (Riverhead Books). That fear, she says, drives well-meaning mothers and fathers to send their misbehaving teens to “tough-love” programs, where they’re subjected to abusive treatment in the name of helping them.

Based on her own research, Szalavitz estimates that between ten and twenty thousand American teens are forced into “boot camps,” “emotional-growth centers,” and “behavior-modification programs” each year. The industry is unregulated, and some programs operated by U.S. companies place children in facilities outside the U.S. What tough-love programs all have in common, Szalavitz says, is the belief that teens should be made to conform to the expectations of parents and society, by whatever means necessary. Critics have accused the programs of using beatings, extended isolation and restraint, public humiliation, food deprivation, sleep deprivation, sensory deprivation, forced exercise to the point of exhaustion, and lengthy maintenance of “stress positions.” Research shows that tough treatment is not effective, Szalavitz says, and can even be harmful.
