Volunteer Functions Inventory (VFI) is a research method for assessing volunteer motivations.
The model has been developed by Clary et al. in 1998.
[1][2] Having analyzed several dozens of studies using this framework, Chacón et al. found that the most common motivation for volunteering is the values dimension, and the least, career and enhancement ones.
Career and understanding motivations decrease with the mean age of volunteers, and men seem to be more likely to consider the social dimension than women.
