Translation and Psychometric Properties of the Persian Version of the Sensory Profile 2

Background and Aim : Achieving an effective and reliable evaluation tool for measuring sensory processing in infants, children and adolescents is necessary. The ultimate aim of the present study was to investigate the psychometric properties of sensory profile 2 to provide an appropriate tool for sensory processing.Methods : After translating and obtaining the views of rehabilitation specialists and experts in Persian literature, the face and content validity of the assessment was determined by a survey of 20 rehabilitation professionals. To determine the construct validity of the convergence type, the comparison of the dimensions of the sensory profile 2 and adolescent-adult sensory profile and the Vineland adaptive behavior scale were used. The determination of reliability was carried out by analyzing the internal consistency and the test-retest in the 0 to 14 year old populations.Results : In this study, 1272 parents and teachers from 0 to 14 years old who were referred to comprehensive centers of urban health and schools in Tehran participated. After calculating the score, the item impact with values higher than 1.5, content validity ratio was more than 0.42 and content validity index was higher than 0.79 all items of sensory profile 2 enumerated. Significant negative correlation between touch processing dimension from the toddler s sensory profile 2 and socialization of the Vineland adaptive behavior scale were reported (P < 0.05). There was a direct and significant correlation between the sensory avoiding aspects of adolescent-adult sensory profiles with all dimensions of the short sensory profile 2 (P < 0.05, r = 0.26, r = 0.62). The range of intra class correlation for the test-retest reliability of the test was in the range of 0.72 to 0.95 and the Cronbach s alpha coefficients were in the range of 0.61-0.91.Conclusion : The Persian version of Sensory Profile 2 has an acceptable validity and reliability and is usable for sensory processing measure.
