Volunteer Satisfaction Index (VSI)

A Global Gauge

Assessing Altruism

Established in 1999, the Volunteer Satisfaction Index (VSI) has become a pivotal tool in global volunteerism research. Recognized for its robust psychometric properties, the VSI is a trusted measure for assessing volunteer satisfaction.


With references from more than 355 scholars, its applicability stretches across diverse nonprofit realms including Sports, Social, Religious, Emergency, Military, and Healthcare. Its influence is evident in nations such as China, Serbia, Italy, the United States, and beyond.

Organizations seeking to administer the Volunteer Satisfaction Index may  request a rate sheet from the developer.
