title: The "Reading the Mind in the Eyes" Test: Investigation of Psychometric Properties and Test-Retest Reliability of the Persian Version.
abstract: The psychometric properties of the Persian "Reading the Mind in the Eyes" test were investigated, so were the predictions from the Empathizing-Systemizing theory of psychological sex differences. Adults aged 16-69 years old (N = 545, female = 51.7 %) completed the test online. The analysis of items showed them to be generally acceptable. Test-retest reliability, as measured by Intra-class correlation coefficient, was 0.735 with a 95 % CI of (0.514, 0.855). The percentage of agreement for each item in the test-retest was satisfactory and the mean difference between test-retest scores was -0.159 (SD = 3.42). However, the internal consistency of Persian version, calculated by Cronbach's alpha (0.371), was poor. Females scored significantly higher than males but academic degree and field of study had no significant effect.
