2.3.2. Data Collection

To measure program implementation, the research team collected both qualitative and quantitative data using multiple tools. For each design team meeting, the research team completed field logs and debriefing notes to measure dose (frequency and duration of meetings) and fidelity to the HWPP materials and IDEAS Tool, and rated four dimensions of team member engagement (offered new ideas during meetings, actively participated in meeting, completed homework, and discussed projects with co-workers) on a 3-point scale (0 = no; 0.5 = somewhat; 1 = yes). The design team also rated their own participation and completed meeting reflections [53]. After the completion of the program, the design team members completed semi-structured interviews and a short survey to record final perceptions of both the program and the team's ability to move forward with implementing solutions without the support of the research team. All store workers were surveyed about their awareness and utilization of the implemented activities three months after they were implemented. The survey asked what changes related to health and wellness they had noticed in their store over the study period, and if they had participated in any of the health activities. We asked if any of the activities "helped them improve (their) eating/and or exercise habits," what limitations prevented them from participating in the health activities listed, and if the activities were relevant to their life. We also conducted semi-structured interviews with five store workers to further gauge their perceptions of the activities implemented in their workplace.

#### 2.3.3. Data Analysis

We used SPSS v. 23 (IBM, Armonk, NY, USA) to run descriptive statistics for baseline demographics and with store worker follow up surveys for program reach metrics (i.e., awareness and use of activities). We rated all process components according to the measures described in our logic model. A process measure of design team participation was the average rating of each team member's engagement scores across meetings. Qualitative data was not systematically coded, but each qualitative item was reviewed with consensus by the research team to summarize each process measure. Qualitative data was also used to provide descriptive information to support the quantitative results.
