The impact of panel composition and topic on stakeholder perspectives: Generating hypotheses from online maternal and child health modified-Delphi panels

Introduction

Multistakeholder engagement is crucial for conducting health services research. Delphi‐based methodologies combining iterative rounds of questions with feedback on and discussion of group results are a well‐documented approach to multistakeholder engagement. This study develops hypotheses about the impact of panel composition and topic on the propensity and meaningfulness of response changes in multistakeholder modified‐Delphi panels.

Methods

We conducted three online modified‐Delphi (OMD) multistakeholder panels using the same protocol. We assigned 60 maternal and child health professionals to a homogeneous (professionals only) panel, 60 pregnant or postpartum women (patients) to a homogeneous panel, and 30 professionals and 30 patients to a mixed panel. In Round 1, participants rated the seriousness of 11 maternal and child health outcomes using a 0–100 scale and explained their ratings. In Round 2, participants saw their own and their panel's Round 1 results and discussed them using asynchronous, anonymous discussion boards moderated by the study investigators. In Round 3, participants revised their original ratings. Our outcome measures included binary indicators of response changes to ratings of the low, medium and high severity maternal and child health outcomes and their meaningfulness, measured by a change of 10 or more points.

Results

Participants changed 818 of 1491 (55%) of responses; the majority of response changes were meaningful. Patterns of response changes were different for patients and professionals and for different levels of outcome seriousness. Using study results and the literature, we developed three hypotheses. First, OMD participants, regardless of their stakeholder group, are more likely to change their responses on preference‐sensitive topics where there is a range of viable alternatives or perspectives. Second, patients are more likely to change their responses and to do so meaningfully in mixed panels, whereas professionals are more likely to do so in homogeneous panels. Third, the association between panel composition and response change varies according to the topic (e.g., the level of outcome seriousness).

Conclusions

Results of our work not only helped generate empirically derived hypotheses to be tested in future research but also offer practical recommendations for designing multistakeholder OMD panels.

Nature and Predictors of Response Changes in Modified-Delphi Panels

OBJECTIVES

To describe the extent and nature of changes in participants' responses after exposure to group feedback and discussion in modified-Delphi panels and to identify factors affecting those changes.

METHODS

We analyzed data from 2 online modified-Delphi panels, each consisting of 2 rating rounds and an online discussion round. We included responses from 55 participants who answered 38 questions in both rating rounds. Because not all participants answered each question twice, our sample consisted of 1846 cases (response changes). We used mixed-effect logistic and multinomial logistic regression to identify factors predicting response changes and their direction relative to group median-our consensus measure.

RESULTS

Participants changed, on average, 49% of their responses. A response was changed in 47% of the 1846 cases: 28% of responses were changed toward consensus and 19% away from it. Although some measures of subjective participation experiences had a marginally significant impact on the propensity and direction of response changes, several objective measures of discussion engagement were statistically significant predictors of both the presence and direction of response changes.

CONCLUSION

Our results illustrate the nature of response changes and highlight the importance of exposing participants to alternative perspectives and encouraging them to explain their perspectives.
