Son-Rise is a home-based program that emphasizes on implementing a color- and sensory-free playroom. Before implementing the home-based program, an institute trains the parents how to accept their child without judgment through a series of dialogue sessions. Like Floortime, parents join their child's ritualistic behavior for relationship-building. To gain the child's "willing engagement", the facilitator continues to join them only this time through parallel play. Proponents claim that children will decide to become non-autistic after parents accept them for who they are and engage them in play. The program was started by the parents of Raun Kaufman, who is claimed to have gone from being autistic to normal via the treatment in the early 1970s. No independent study has tested the efficacy of the program, but a 2003 study found that involvement with the program led to more drawbacks than benefits for the involved families over time, and a 2006 study found that the program is not always implemented as it is typically described in the literature, which suggests it will be difficult to evaluate its efficacy.
