Evaluating the Hans Kai Program for Canadian Adults Via an 18-month Mixed Methods Randomized Controlled Trial

The Hans Kai trial will follow a prospective mixed methods intervention design involving an RCT and an interpretative descriptive qualitative study. The mixed methods intervention design is a mixed methods approach to research in which the collection, analysis, and integration of both quantitative and qualitative data are embedded within an experimental quantitative research design. The objective of gathering qualitative data within an experiment, along with the quantitative data on the outcome measures, is to gain an understanding of the personal, contextual experiences of the study participants.

In this mixed methods intervention study design, quantitative data on the outcomes of interest will be collected along with qualitative data on the experiences of program participants and facilitators, and integrated within an intervention trial (i.e., RCT) to address the research objectives (see next section for details). The primary research design in this study will be a quantitative intervention trial or RCT that will follow a pragmatic randomized wait-list-control design with an 18-month follow-up. The RCT will involve the collection, analysis, and interpretation of quantitative data (self-reports and objective indicators) on primary, secondary, and tertiary outcomes that will be gathered to evaluate the effectiveness of the Hans Kai program in promoting the health and wellbeing of Canadian adults. To enrich the RCT results, the secondary qualitative strand of the study will be added during and after the intervention by embedding a combination of convergent and explanatory sequential designs into the RCT.
