Caregivers in both interventions demonstrated improvements across all psychological outcomes (creative agency, p < 0.001; self-efficacy, p = 0.015; positive affect, p < 0.001; negative affect, p < 0.001; perceived stress, p < 0.001; anxiety, p = 0.002; burnout, p = 0.041). There was no evidence of change in any of the biomarkers (cortisol, IL-6, and CRP) measured. Here, IL6 is linked to Anxiety.
