Adaptation of Organ Donation Attitude Survey: Reliability and Validity Maintained as Demonstrated in a Turkish Population

Abstract

Inadequate organ donation has become a major public health concern for society, particularly for patients with chronic organ failure. This study aims to regulate the validity and reliability of the Organ Donation Attitude Survey scale in the Turkish population, which was developed by Rumsey et al in 2003. The study was conducted on 1088 students studying at the faculty of nursing and vocational school of health services. Data were analyzed using SPSS 26.0 and AMOS 24.0. After language adaptation, Exploratory Factor Analysis and Confirmatory Factor Analysis were made. The Composite Reliability and Cronbach α (CA) values were used to evaluate the reliability and structure reliability of the scales used in the study. The mean age of the participants was 20.34 ± 1.48 years. Of the participants, 764 (70.2%) were female, and 324 (29.8%) were male. The Composite Reliability coefficients for Supporting Organ Donation, Positive Belief for Organ Donation, and all of the Organ Donation Attitude Survey scale were 0.916, 0.755, and 0.932, respectively. The Cronbach α coefficients were 0.913, 0.750, and 0.906, respectively. Analyses results revealed that the Turkish version of the scale had 2 subdimensions (Supporting Organ Donation and Positive Belief for Organ Donation) and 14 items (χ2/df = 3.111, Goodness of Fit Index= 0.985, Adjustment Goodness of Fit Index = 0.980, Normed Fit Index = 0.979, Relative Fit Index = 0.975). Fit indices and reliability coefficients were acceptable. In conclusion, the Turkish version of the Organ Donation Attitude Survey is valid and reliable and can be used in future studies.
