Attitudes toward posthumous organ donation and commitment to donate

Area of Science:

• Medical Social Science
• Public Health
• Health Psychology

Background:

• The demand for transplantable human organs significantly outweighs the available supply.
• Increasing organ donation pledges requires understanding and improving public attitudes toward donation.
• Effective public health campaigns necessitate data on current public perceptions of organ donation.

Purpose of the Study:

• To measure public attitudes toward organ donation using verbal scales.
• To identify distinct dimensions of prodonation and antidonation beliefs.
• To determine the relationship between attitudes and willingness to sign donor cards.

Main Methods:

• Development and administration of verbal attitude scales to 110 adults.
• Reliable measurement of two independent attitude dimensions: prodonation and antidonation.
• Cluster analysis to explore the components of positive and negative attitudes.
• 2x2 analysis of variance to examine attitude interactions and willingness to sign donor cards.

Main Results:

• Two independent dimensions of attitudes were reliably measured: prodonation (humanitarian benefits, donor pride) and antidonation (fears of mutilation, inadequate medical care).
• Both pro and antidonation scores significantly predicted willingness to sign a donor card.
• A significant interaction effect showed that individuals with strong positive and weak negative attitudes were most willing to sign donor cards.

Conclusions:

• Public attitudes toward organ donation are complex, encompassing both positive beliefs and negative fears.
• Educational campaigns should address and mitigate common fears while highlighting the humanitarian benefits and pride associated with organ donation.
• Targeting individuals with strong positive and weak negative attitudes may be particularly effective for increasing donor card sign-ups.
