This self-report tool is based on Dunn’s model [4] and includes 60 questions about the respondent’s behavior with sensory experiences in daily living in all sensory modalities. The 60 items are sorted equally into the four quadrants of Dunn’s model—low registration, sensation seeking, sensory sensitivity, and sensation avoiding (based on factor analysis)—and reflect various sensory-processing patterns. Each quadrant provides information on multiple sensory systems. Participants indicate how often they respond to the sensory event in the manner described using a 5-point Likert scale from 1 (almost never) to 5 (almost always). Each quadrant’s resultant score can range from 5 to 75. Norms are described for each age group (11–17 years; 18–64; 65 and older). Scores under or above these norms are considered alterations in sensory-processing abilities. This questionnaire has good internal consistency with coefficient alpha values of .692 to .699 for the four quadrants. In the present study the validated Hebrew version was used [37].
