The draft scale consisted of 74 items, and it was applied to 746 university students. Cronbach Alpha coefficient was found 0.91, and the test–retest reliability coefficient was 0.814. Eight factors consisting of 28 items, explaining 65 % of total variability were obtained in the factor analysis done with varimax rotation for the construction of validity. The factorial model of scale was found theoretically and statistically convenient after the confirmatory factor analysis. The results indicated that Sexual Myths Scale (SMS) is a valid and reliable instrument in Turkey.
