The SPM-2 is an upgrade and expansion of the Sensory Processing Measure family of products, widely acclaimed as the best of its kind. A behaviour rating scale, the SPM-2offers new forms – including driving forms – and a broadened age range, so no one gets left behind. The new SPM-2 is firmly grounded in Ayres Sensory Integration® theory. T‑scores provide norm-referenced indexes of the integrative functions of praxis and social participation, as well as the following sensory systems: Visual Auditory Tactile Olfactory, and Gustatory (new) Proprioceptive Vestibular. The SPM‑2 items provide descriptive clinical information on processing vulnerabilities within each sensory system, including under- and over-reactivity, sensory-seeking behaviour, and difficulties with perception. The forms at each age level are designed for maximum flexibility in choosing and comparing among environments and raters, such as multiple caregivers.
