Grassroots involvement in interest group decision making

Interest groups' increased use of centrally managed mass communications technologies has reduced opportunities for social networking among group members. This study examines the relationship between organizational democracy, or rank-and-file participation in decision making, and two indicators of social network opportunities: existence of local chapters and extent of direct-mail usage. Control variables include membership incentives, organizational resources, group age and size, and competition with other groups for members. Multivariate analyses of two interest group survey datasets, using ordinal legit, indicate that social network organizations are no more likely to involve their members in decision making than are centralized direct-mail organizations. The variables that are significantly related to grassroots involvement in organizational decision making include purposive and solidary membership incentives as well as some organizational resources, size, and age Implications for further study of organizational democracy are discussed.
