Efficacy of Interventions Adhering to the Revised Ayres Sensory Integration® Fidelity Measure: A Systematic Review

Sensory integration therapy is used widely despite an inconsistent evidence base. To overcome the limited availability of high-quality research, Ayres Sensory Integration (ASI) was manualized and a revised fidelity measure was developed following the identification of the principles of ASI®. The aim of this systematic review is to examine the proximal and distal effects of interventions in studies that explicitly reported the use of or adherence to the process elements of the fidelity measure.

Abstract:
Sensory integration therapy is used widely despite an inconsistent evidence base. To overcome the limited availability of high-quality research, Ayres Sensory Integration (ASI) was manualized and a revised fidelity measure was developed following the identification of the principles of ASI®. The aim of this systematic review is to examine the proximal and distal effects of interventions in studies that explicitly reported the use of or adherence to the process elements of the fidelity measure.
