Introduction
The purpose of this study was to translate and cross-culturally adapt the original Sensory Profile 2 questionnaires to Persian and access the psychometric properties of the adapted questionnaires.
Method
The translation and cultural adaptation of the original questionnaires were carried out under the published guidelines. Furthermore, we employed the multiple methods to establish the validity and reliability of the Sensory Profile 2 questionnaires. We calculated the content validity, internal consistency, and test–retest, along with the standard error of measurement. The study included 1272 children, between 0 and 14 years old, without any disabilities. They were selected from child developmental centers and elementary and middle schools of Tehran, the capital of the Islamic Republic of Iran.
Results
The item-level content validity index and the scale-level were satisfactory for all the items, quadrant, section, and factor of the Sensory Profile 2. The values of alpha for all questionnaires were ranged from 0.67 to 0.91. Furthermore, the test–retest reliability values for all questionnaires ranged from 0.72 to 0.95.
Conclusions
The Sensory Profile 2-Persian version can considered as a valid and reliable tool for utilization in Persian-speaking children between 0 and 14 years old.
