The test was applied to a total number of 100 students at 14 and 9 years of age.

There was no item that’s CVI was less than 0.79, and according to the Lawshe method, the CVR was above 0.73. Conclusion: The Persian version of the "TOPL-2" is a standard tool, with appropriate reliability and validity.
