University Student Volunteering (USV): Instruments for Its Comprehensive Diagnosis (ICD-USV)

open access: yesThe Qualitative Report, 2021
University Student Volunteering (USV) requires attention to guarantee its pedagogic quality and its fulfilment of community service. However, a review of the literature reveals a lack of tools for assessing the quality of USV. Thus, our research question was: how can we evaluate the efficacy of volunteer programs in higher education?
