  1. Bolded p-values indicate statistical significance at the .05 level.
  2. aCoefficients were opposite in sign compared to the rest of the results because gratitude was reflected (i.e., reversed).
  3. bp-value adjustments were conducted taking into account all three dependent variables (triglycerides, LDL, HDL) across the first three models (i.e., a total of nine p-values).
