Study of The Psychometric Properties of the Sensory Profile - First Edition

Abstract

The objective of this research is to extrapolate Syrian edition of Sensory Profile –first edition, which has been achieved by studying the scale psychometric characteristics (the scale validity and the scale reliability). In order to achieve this target, the scale was applied to a sample which consists of (518) typical children who are aged between 3 - 8.11. The study concluded the below results:

The scale validity was verified using few methods that included the structural validity which was verified by applying factor analysis, and it was concluded that the sub domains of the scale are loaded by a four factors explaining 58.08 % of the overall variance, And the Items of the scale are loaded by nine factors explaining (36.625%) of overall variance. Also, the structural validity was proven using the internal consistency method and they all were statistically indicative. While for the scale’s reliability, it was verified utilizing few methods that are Cronbach’s alpha coefficient reliability, verifying the reliability by retest test and split-half method. All the results have promoted the scale reliability and they all were statistically indicative.
