This study investigates the factors influencing social media users' intent to donate online to international NGOs (INGOs) in the age of fake news. Utilizing the Theory of Planned Behavior (TPB), the researchers employed an online survey of 1629 potential donors in Romania. Structural equation modeling revealed that social media usage and INGO brand reputation positively impact fake news sharing, perceived donation risks, attitudes toward online donations, and INGO brand image. These findings offer insights for communication specialists to enhance online donations to INGOs amidst misinformation.
