The Adaptation and Psychometric Properties of the" Sensory Processing Measure-Preschool" in Children

The aim of this study was investigating psychometric properties of the Sensory Processing Measure-Preschool (SPM-P) to achieve a reliable tool for measuring the sensory processing Challenges of children. This research was a descriptive of analytical kind. After translation, adaptation and some modifications, 384 children aged between 2 and 5 years of kindergartens in the city of Tehran was chosen by multi-stage sampling. The Sensory Processing Measure-Preschool (SPM-P) was performed on them. Psychometric analyses within the context of content validity, construct validity and reliability was done. The results showed that the sub scales, as well as the whole scale, content validity and construct validity was desirable. In addition, the evidence from different sources and analyses represented the internal and external consistency of the scale (P=0/000). The Cronbachchr('39')s alpha used to examine the reliability. The Cronbach’s alpha value for the whole questionnaire was 0.83 and for some scales, it was at least 0.75. Upon the result, we can interpret that the Sensory Processing Measure-Preschool was a reliable tool that can be used to measure the capability of sensory processing, praxis and social participation of Iranian children and it can be used in health clinics and educational centers for screening purposes and research activities.
