Construction, Validity and Reliability of Organ Transplantation Attitude Scale in Iran

Considering the importance of studying the factors affecting organ transplantation in Iran, the present research aims at examining the factor structure, reliability and validity of the organ transplantation attitude scale. The method of research was descriptive survey. A sample of 210 students, who were selected using multistage cluster sampling, completed the questionnaire. The validity of the questionnaire was assessed using content validity, construct validity and factorial validity. The reliability of the questionnaire was examined through Cronbach's alpha coefficient. The pattern of correlation coefficients between the subscales indicated a good construct validity of the scale. The results of exploratory-confirmatory factor analysis were also indicative of good and acceptable fit of items. Moreover, the Cronbach's alpha coefficients for all subscales and total scale were desirable regarding psychometric properties, and reliability coefficient was also good. Considering the results of the study, the scale constructed in the Iranian society can be said to have good validity and reliability. It can be used to assess the factors influencing organ transplantation in Iran.
