The participants were intially screened by the occupational therapist for inclusion based on clinical testing through the use of the somatosensory component of the Southern California Sensory Integration Tests (
SCSIT) (Ayres, 1972), tactile sensitivity reported in a parent questionnaire, information gathered during a parent interview, and clinical observations of the child's response to touch during play.
While there are other tools, e.g., the Southern California Sensory Integration Test (
SCSIT), and Clinical Observation and Chinese Sensory Profile, the publisher stopped selling
SCSIT after the development and standardization of the SIPT.
