Abstract

The current study aimed to evaluate the validity and reliability of the 5th revision of identity styles Inventory (ISI-5) in a group of Iranian adolescents. ISI-5 was translated from English to Persian, and then the Persian version was edited by 5 experts in psychology and English language, back-translated from Persian to English by another translator and was confirmed by the author of the source version. The final Persian version of ISI-5 was administered among 373 high school students (189 female, 184 male) of Shahriar (Shahriar, Tehran Province, Iran) who were selected through multi-stage cluster sampling method. The reliability of the scale was determined by Cronbach's alpha and test-retest; and validity of the scale was confirmed by simultaneous validity and confirmatory factor analysis. Cronbach’ s alpha coefficients for the three sub-scales of this test were between 0/67 and 0/79. The test-retest coefficients of the three subscales of the Persian version of ISI-5 were between 0/77 and 0/81. The findings indicated that the Persian version of ISI-5 has a good validity and reliability for Iranian sample and is applicable in research cases.
