A thesis entitled “Individual and social motivations to contribute to Commons-based peer production” was submitted by University of Minnesota student Yoshikazu Suzuki for an MA in mass communication. The thesis presents and discusses the results from a small series of interviews as well as a survey exploring individual and social motivations of Wikipedia contributors, drawing on social identity theory, volunteerism and uses and gratifications theory. The survey, run in July 2011 with support from the Wikimedia Research Committee, collected 208 responses from a random sample of 950 among the top English Wikipedia editors.

The results, obtained by applying principal components analysis to the responses, reveal eight distinct motivational factors: providing information, the seeking of creative stimulation, concern for others’ well-being, the need to be entertained, the avoidance of negative self-affect, cognitive group membership, career benefits, and social desirability. An analysis of the relative strength of each factor indicates that providing information, the seeking of creative stimulation, and concerns for others’ well-being were the three strongest motivational dimensions. Grouping the eight factors into two macro-categories according to self- and other-focused motivations, the other-focused motivations were found to be significantly stronger than the self-focused motivations. The thesis reviews the implications of these results for the design of incentives for participation and editor retention.
