One-on-one therapy is extremely important in most cases, particularly at the onset of therapeutic services, when teaching new and challenging skills, and when reducing problem behaviors. Individual therapy in a controlled environment is essential early-on to maximize an individual’s potential and fully develop their repertoire of skills, in addition to reducing problem behaviors before they become an established pattern. Once certain skills have been strengthened and generalized, one-on-one therapy becomes less essential, and other socially-related skills can be addressed in other settings and therapeutic arrangements. Even then, one-on-one therapy is the most effective way to promote and maintain acquisition of new skills.
