Our aim was to evaluate the reliability and validity of a Turkish version of the Trust in Nurses Scale (TNS). A group of people living in Turkey and receiving treatment for lung cancer at a chest hospital completed the scale. We assessed construct validity of the TNS using confirmatory factor analysis. We evaluated the reliability of the scale using coefficient alpha and the result for the internal consistency reliability of the scale was a coefficient alpha of .95. According to our results, the Turkish version of the TNS is a valid and reliable tool for the evaluation of trust in nurses among people in Turkey being treated for lung cancer.
