Opinion Leaders

Individuals in an organization who have formal or informal influence on the attitudes and beliefs of their colleagues with respect to implementing the intervention. 

Taxonomy

Domain: Process

Construct: Engaging

Individuals in an organization who have formal or informal influence on the attitudes and beliefs of their colleagues with respect to implementing the intervention [1][2]. There is general agreement that there are 2 different types of opinion leaders: 1) experts; and 2) peers [3]. Expert opinion leaders exert influence through their authority and status [1]. Peer opinion leaders exert influence through their representativeness and credibility [1]. Rogers defines opinion leaders in terms of the degree to which an individual is able to influence other attitudes or overt behavior informally in a desired way [2]. But opinion leaders can also exert a strong negative effect as well [3]. External change agents often use opinion leaders in a social system as “lieutenants” in diffusion activities [2]. Opinion leaders can lose respect of their peers if they come to be regarded as a professional change agent [2]. The role and definition of opinion leaders is varied and complex. Its effect on promoting use of interventions is mixed based on a review of randomized control trials ranging from -6% to +25% in improving behaviors of healthcare professionals [4].

Inclusion Criteria

Include statements related to engagement strategies and outcomes, e.g., how the opinion leader became engaged with the innovation and what their role is in implementation. Note: Although both strategies and outcomes are coded here, the outcome of efforts to engage staff determines the rating, i.e. if there are repeated attempts to engage an opinion leader that are not successful, or if the opinion leader leaves the organization and this role is vacant, the construct receives a negative rating. In addition, you may also want to code the “quality” of the opinion leader here – their capabilities, motivation, and skills, i.e. how good they are at their job, and this affects the rating as well.
