Snoezelen multi-sensory environments: Task engagement and generalization

These experiments explored whether behavioral improvements observed during Snoezelen OT treatment sessions carried over to two different settings for three people with moderate/severe intellectual disability, autism and severe challenging behaviors. Experiment 1 explored engagement during a functional task immediately following the treatment sessions while experiment 2 explored changes in the frequencies of challenging behaviors on the days after treatment sessions. Investigators found carryover for two of the three participants to both post-session engagement as well as to the daily frequency of challenging behaviors on days following the OT sessions.
