In the United States all legally incorporated non-profit organizations are required
to have boards of directors. The members of these boards are unpaid volunteers.
This paper examines the reasons board members participate. A triad of data collec
tion techniques—questionnaires, interviews, and observations-was used to study
the members of the boards of directors of ten human service agencies. The study is
based on an incentive approach to participation, which suggests that participation
occurs in response to incentives, the expectation of valued outcomes. Four catego
ries of incentives-material, social, developmental, and ideological—are used to or
ganize the data. The study demonstrates that board members have multiple and
complex incentives for participation, that some members achieve an adequate num
ber of incentives and some do not, that few members participate in response to in
centives that are dependent on specific policy outcomes and that even fewer serve as
consumer representatives, and that there are differences among agencies in board
members' reasons for serving. Implications for board recruitment and retention are
discussed.
