Background: Long-term financial support is essential for the survival of a charitable organization. Health charities need to identify
the effective factors influencing donor retention.
Methods: In the present study, the items of a questionnaire were derived from both literature review and semi-structured interviews
related to donor retention. Using a purposive sampling, 300 academic and executive practitioners were selected. After the follow- up, a
total of 243 usable questionnaires were prepared for factor analysis. The questionnaire was validated based on the face and content
validity and reliability through Cronbach’s α-coefficient.
Results: The results of exploratory factor analysis extracted 2 factors for retention: donor factor (variance = 33.841%; Cronbach’s α-
coefficient = 90.2) and charity factor (variance = 29.038%; Cronbach’s α-coefficient = 82.8), respectively. Subsequently, confirmatory
factor analysis was applied to support the overall reasonable fit.
Conclusions: In this study, it was found that repeated monetary donations are supplied to the charitable organizations when both
aspects of donor factor (retention factor and charity factor) for retention are taken into consideration. This model could provide a perspective
for making sustainable donations and charitable giving.
