An 18-month study of consumer participation and influence in a Health Systems Agency (HSA)found consumer board members to be less influential than provider board members in agency decision-making. In an effort to investigate causes of the influence deficit experienced by consumer HSA board members three issues were studied: staff attitudes toward consumer participation; board member degree of representative accountability; and board member attitudes concerning commitment to consumer participation, commintment to health planning, health services attitude, and feelings ofsocial powerlessness. Results indicated that staff members ivere favorable toward the concept of consumer participation. They recognized a lack of low-income minority participation, but they did not provide support or allocate resources to enhance consumers' ability to participate. Providers were less committed to consumer participation, felt more socially powerful, and had greater representative accountability than did consumers. Several strategies for increasing consumer influence in HSA decision-making processes are proposed.
