RESULTS: The results showed that 3 questions had lower content validity which were rejected and also the content validity and Cronbachs α got the acceptable scores of 0.8 and 0.95, in respect. CONCLUSIONS: According to the used clothing in Iran, this study can reveal the insufficient supply of visible clothing, inadequate use of visible clothing in society and little knowledge of people in this field.
