Abstract

Objective: The purpose of the present study was to establish the item analysis and internal consistency of the Persian version of the Child Sensory Profile 2 in 2 groups of typical and atypical children (autism spectrum disorder and learning disabilities) aged 3 to 14 years.

Method: The sample of this study included 120 typical and atypical children aged 3 to 14 years who referred to schools and rehabilitation centers in Tehran were selected using multistage sampling method. To collect data, the Child Sensory Profile 2 questionnaire was used, which is a set of questionnaires of the Sensory Profile 2. To analyze the data, the discrimination index was used to determine the discriminant validity of the Child Sensory Profile 2, and the Cronbach's alpha coefficient was used to determine the reliability in terms of internal consistency.

Results: Discrimination index was satisfactory for all the items of the Child Sensory Profile 2. The values of Cronbach's alpha ranged from 0.795-0.919 in typical children and 0.617-0.901 in autistic children, and 0.792-0.920 in children with learning disabilities.

Conclusion: The Persian version of the child sensory profile 2 is a valid (discrimination with vulnerable populations) and reliable (internal consistency) tool for assessing sensory processing.
