The Benefits and Complexities of Integrating Mixed Method Findings Using the Pillar Integration Process: A Workplace Health Intervention Case Study
Jennifer Hall, Louise Mansfield
Abstract
The Pillar Integration Process was developed to facilitate integration of mixed method data, but there is limited historical application of this approach in complex intervention evaluation. To test the applicability of the technique, this paper presents two case studies examining the efficacy of a workplace intervention. The research included a pilot RCT and process evaluation. The case studies illustrate the benefits of applying the Pillar Integration Process to elicit a comprehensive understanding of intervention efficacy and to design better interventions. This paper contributes to the mixed methods research by advancing the technique through considering inherent philosophical assumptions, and evidencing the value of integrating methods within, as well as across, “qualitative” and “quantitative” categories.
