The adult sensory profile: Measuring patterns of sensory processing

Objective. This article describes a series of studies designed to evaluate the reliability and validity of the Adult Sensory Profile. Method. Expert judges evaluated the construct validity of the items, Coeffi cient alpha, factor analysis, and correlations of items with subscales dete rmined item reliability, using data from 615 adult sensory profiles. a subs ample of 20 adult furnished skin conductance data. A heterogeneous group of 93 adults completed the revised Adult Sensory Profile, and item reliabilit y was reexamined. Results. Expert judgement indicated that times could be categorized accordi ng to Dunn's Model of Sensory Processing. Results suggested reasonable item reliability for all subscales except for the Sensation Avoiding subscale. Skin conductance measures detected distinct patterns of physiological respo nses consistent with the four-quadrant model. Revision of the Adult Sensory Profile resulted in improved reliability of the Sensation Profile subscale . Conclusion. The series of studies provides evidence so support the four sub scales of the Adult Sensory Profile as distinct constructs of sensory proce ssing preferences.
