Predictors of monetary donations to victims of humanitarian disasters were examined. Participants (N = 219) chose between donating to different scenarios and justified their choices in an open response format. This was followed by a questionnaire. The perceived extent of the victims’ Need, the Impact of a potential donation, and the Amount donated by others all influenced donation decisions. There was a three-way interaction between these factors: The perceived Need for help only mattered if the perceived Impact of a donation was high, and the perceived Amount donated by others was small. Implications for theory and practice are discussed.
