Convergent parallel mixed methods will be used to integrate the quantitative and qualitative data on patient activation measured via the Patient Activation Measure at 12 and 24 weeks using the analytic framework described in the primary outcome. Qualitative analysis will involve in-depth immersion in the transcripts and audio and the iterative creation and synthesis of analytical memos and codes to organize data toward thematic insights. The investigators will use a deductive-dominant approach wherein a subset of central codes are determined a priori to focus the analysis, with inductive emergence of additional codes during analysis. The investigators will use Nvivo to facilitate coding and analysis. Mechanistic understanding of observed cardiovascular health will ultimately be enhanced via narrative based integration of qualitative and quantitative data.

Evaluation of hair cortisol measured via collection of hair from the vertex of the scalp at baseline, 12, and 24 weeks. Changes in hair cortisol over time. which will be calculated using between-subject differences rather than within-subject differences, using a linear mixed-effects to evaluate changes from baseline in hair cortisol. Study wave will be a covariate in the models. The model will contain data from baseline (0 weeks), during-intervention (12 weeks), and post-intervention (24-weeks). These models will assess differences between waitlist control and intervention participants using an interaction between time and treatment indicator. Residual plots will examine model assumptions and model fit, with transformation of the outcomes (e.g. log, square-root, Box-Cox) used as needed to satisfy modelling assumptions (e.g. normality, constant variance) and achieve appropriate model fit.

To determine the context and resources necessary to align, coordinate and sustain partnerships to advance health equity we will perform interviews with partners in the Black Impact intervention, take notes on partner meetings and review organizational documents. Through qualitative thematic analysis and structured content analysis of notes taken during on-site contextual inquiry and excerpts from key organizational documents we will develop themes. The themes, within and across data sources, will be summarized visually and narratively for presentation to organizational stakeholders during a series of co-creation sessions during which stakeholders will leverage insights from qualitative analyses to discuss and detail actions that can lead to greater alignment and coordination for current and future delivery of Black Impact and similar programs aimed at advancing cardiovascular health equity through academic-community-government partnerships.
