The Clinical Global Impression - Severity scale (CGI-S) is a 7-point scale that requires the clinician to rate the severity of the patient's illness at the time of assessment, relative to the clinician's past experience with patients who have the same diagnosis. Considering total clinical experience, a patient is assessed on severity of mental illness at the time of rating 1, normal, not at all ill; 2, borderline mentally ill; 3, mildly ill; 4, moderately ill; 5, markedly ill; 6, severely ill; or 7, extremely ill. The Clinical Global Impression - Improvement scale (CGI-I) is a 7 point scale that requires the clinician to assess how much the patient's illness has improved or worsened relative to a baseline state at the beginning of the intervention. and rated as: 1, very much improved; 2, much improved; 3, minimally improved; 4, no change; 5, minimally worse; 6, much worse; or 7, very much worse.

The SP is a standardized parent-completed questionnaire that assesses sensory processing and its impact on the functioning of children ages 3-10 yr. The 125 items represent behaviors that can be interpreted as responses to sensory experiences. The parent rates the observed frequency of these behaviors on a 5-point Likert scale (ranging from 1 always to 5 never). The tool consists of 14 sections, listed below, that refer to sensory processing, modulation, and behavioral and emotional responses. Subscale scores are listed below. Each section's raw score is compared with a threshold value to determine a category of performance: typical performance, probable difference (1 standard deviation below the mean), and definite difference (2 standard deviations below the mean). A lower raw score means a greater difference.

The Short Sensory Profile is a caregiver report measure consisting of 38 items, each scored on a 1-point (always) to 5-point (never) Likert scale. SSP Subscales Tactile Sensitivity (7 to 35) Taste/Smell Sensitivity (4 to 20), Movement Sensitivity (3 to 15), Under-Responsive/Seek Sensation (7 to 35) , Auditory Filtering (6 to 30), Low Energy/Weak (6 to 30), Visual/Auditory Sensitivity (5 to 25), with total scale from (38 to 190) Lower scores indicate more sensory alterations.
