Interdisciplinary collaboration is an innovative, resourceful approach to healthcare intended to positively affect patient outcomes. The purpose of the present study was to determine the efficacy of the serial exposure to three treatments, Applied Behavior Analysis, Speech Language Pathology, and Occupational Therapy, in comparison with an exposure to a merge of these treatments on child outcomes. During the serial treatment phases of intervention, three licensed professionals implemented core techniques from their respective disciplines. During merged treatment phases, a graduate clinician combined and implemented techniques from all three fields: differential attention, request sequences, sensory exposure, verbal/tactile cueing for postural alignment/control and motor planning, expansion of utterance, access for communication, and use of a visual schedule. Serial and merged treatment phases were implemented across participants within a multiple-baseline design. The child outcomes related to the core techniques include active listening, completion and sequence of activities, duration of postural control, postural alignment, and prone extension, motor planning abilities, frequency of verbalizations, and MLU. This research provides evidence to further support the claim that inter-professional collaboration is an effective approach to healthcare.
