The study features piloting of a cluster-randomized trial to determine whether a positive psychology (PP) intervention is associated with greater improvements in blood pressure compared to an attention control condition. The pilot trial additionally evaluates the efficacy of the PP intervention with respect to psychological well-being, hypertension-related health behaviors, autonomic cardiac control, and high-sensitivity C-reactive protein. Serum blood assays will facilitate exploration of mechanistic indicators linking psychological well-being to cardiac functioning.
