Sensory sensitivity is a composite measurement using the 86 item Sensory Profile 2 (SP-2). SP-2 has 4 quadrants; Seeking (degree child obtains sensory input); Avoiding (degree child is bothered by sensory input); Sensitivity ( degree child detects sensory input); Registration (degree child misses sensory input). SP-2 is completed by parents of subjects using a scale of 5 (almost always = 90% or more), 4 (frequently= 75% of the time), 3 (half of the time = 50%), 2 (occasionally= 25%), 1 (almost never = 10% or less), or does not apply.

Seeking quadrant normal limits are 20-47; elevated seeking scores are ≥ 48, reduced seeking behaviors are ≤ 19.

Avoiding quadrant normal limits are 21-46; elevated avoiding scores are ≥ 47; reduced avoiding scores are ≤ 20.

Sensitivity quadrant normal limits are 18- 42; elevated scores are ≥ 43; reduced scores are ≤ 17 and below. Registration quadrant normal limits are 19-43; elevated scores are ≥ 44; reduced scores are ≤18.

Sensory sensitivity is a composite measurement using the 60-item adolescent/ adult sensory profile (AASP). AASP has 4 quadrants: Low Registration, Sensation Seeking, Sensitivity; Avoiding. Subjects will respond using a scale of almost never (5% or less of the time), seldom (25% of the time), occasionally (50% of the time), frequently (75% of the time), and almost always (95% or more of the time).

Low Registration normal limits are 27-40; elevated scores are ≥ 41; reduced registration scores are ≤ 26.

Sensation seeking normal limits are 42-58; elevated sensation scores are ≥ 59; reduced sensation scores are ≤ 25.

Sensitivity normal limits are 26-40; elevated sensitivity scores are ≥ 41; reduced scores are ≤ 25.

Avoiding normal limits are 26-40; elevated scores are ≥ 41; reduced scores are ≤ 25.
