The questionnaire included 91 questions measuring four scales, including successful identity, premature identity, serotinous identity and troubled identity. 580 high-school students (454 females and 126 males) of Tehran city in the school year 2010-2011 were randomly selected as the sample volume. The construct validity of the questionnaire was assessed by factor analysis of main components and varimax rotation, and four factors were derived from the questionnaire. Moreover, Bennion and Adam's identity status measurement questionnaire and Bem's sex role questionnaire were used to measure the criterion validity of teenager's gender identity questionnaire. The validity coefficient of the questionnaire and its scales was determined by Cronbach's alpha coefficient to fluctuate between 0.73 and 0.82.
