Sensory Phenomena Rating Scales

Measure	Citation(s)	# Items	Domains Probed	Strengths	Limitations
Premonitory Urge for Tics Scale (PUTS)	(Woods, Piacentini et al. 2005)	9 items	Frequency of specific pre-tic related sensory symptoms along with relief after tic completion	Easy to administer and complete	Difficult to administer with younger children who may not recognize or understand urges Does not capture other common sensory phenomeno n in TS besides premonitory urges
University of Sao Paulo Sensory Phenomena Scale (USP-SPS)	(Rosario, Prado et al. 2009)	2 parts: checklist and severity scale	Frequency, interference and distress of sensory phenomena that precede, accompany, or follow tics and other obsessive-compulsive spectrum behaviors	Probes other sensory phenomena such as “just right” feelings, feelings of incompletenes s, inner restlessness. Has symptom checklist to identify common symptoms	Does not have separate domains for different types of sensory phenomena
Sensory Gating Inventory (SGI)	(Hetrick, Erickson et al. 2012)	124 items	6-point Likert ratings assessing 4 factors: perceptual modulation, distractibility, over-inclusion or hyper-attention, and fatigue and stress vulnerability	Has 4 subscales related to different types of sensorimotor gating deficits	Not designed specifically to detect sensory phenomena associated with tics
Structured Interview for Assessing Perceptual Anomalies (SIAPA)	(Bunney, Hetrick et al. 1999)	15 items	5-point Likert ratings of hypersensitivity, inundation and flooding, and selective attention to external sensory stimuli for each of the 5 sensory modalities	Easier to complete than SGI	Not designed specifically to detect sensory phenomena associated with tics Has not been demonstrate d to be elevated in tic disorder patients
