Validation of the Iranian version of the Uncertainty In Illness Scale - Family form

Abstract

This study aimed to evaluate the reliability and validity of the Iranian version of the Uncertainty In Illness Scale — Family form. For this purpose, the Uncertainty In Illness Scale — Family form was translated from English into Persian and tested for psychometric properties. The analyses were carried out with data from a sample of 310 patients’ family members at one general hospital in Birjand city, the center of the Southern Khorasan province. The Iranian version of the Uncertainty In Illness Scale — Family form demonstrated an acceptable level of content validity with a content validity index of 0.91. The Cronbach’s alpha of 0.83 showed that the scale had reasonable internal consistency. This preliminary validation study of the Iranian version of the Uncertainty In Illness Scale — Family form showed that it is an acceptable measure to be used with Iranian patients’ family members. Additional research is recommended for further evaluation of the psychometric properties of the scale.
