"Validation and Reliability of the Instrument Determining Factors in Acceptance of Organ Donation"

Abstract

Donation is the act of giving an organ, tissue, or cells of oneself to another person who needs it with the purpose of improving their state of health. This process involves medical, social, psychological, ethical and economic aspects. The main factors that motivate the population of our country to donate organs are reciprocity, ethics, and morality, while the obstacles to carrying out this donation are the lack of education and awareness on the subject, myths and questions about the safety of the procedures, as well as the Catholic religion and the belief that organ donation can cause the death of the donor. Objective:The objective was measure the validation and reliability of the instrument "Determining factors of organ donation in beneficiaries of the Family Medicine Unit (UMF) No. 20". Material and Methods:An instrument was carried out on a sample of 200 beneficiaries of the UMF No. 20 OOAD Norte of the IMSS in Mexico City, who agreed to answer the instrument, with prior informed consent. Content validity was evaluated by four experts, construct validity by means of exploratory factor analysis (the Kaiser-Meyer-Olkin (KMO) sample adequacy test and Bartlet's sphericity test) and confirmatory factor analysis (using the maximum likelihood estimation procedure) and reliability with Cronbach's alpha coefficient. Results:The instrument presented Cronbach's alpha of 0.911, KMO of 0.731 and Bartlett's sphericity test < 0.05, obtaining two dimensions in the instrument: Social and Cultural. Confirmatory Analysis with expected values in Chi-square x2 31.98; PCMIN/DF 1.99; RMSEA 0.071; CFI 0.983; NFI 0.996 and TLI 0.970. Conclusions:The instrument presented adequate validity and reliability with a clear and interpretable structure.
