Significant associations (p < 4.2 × 10<sup>-3</sup>) after mediator adjustment were observed for single low-grade inflammation markers, including platelet distribution width (with PHQ9-6 and CD-RISC), granulocyte- and neutrophil-to-lymphocyte ratios, monocyte and lymphocyte fractions (with SF36-MCS).
Significant reductions in the IDDI (p < 0.001) and NDDI-E (p < 0.001) scores, improvements in the CD-RISC-10 (p < 0.001) and QOLIE-31 (p < 0.001) scores, and positive correlations between resilience levels and QOL (p < 0.01), as well as a negative correlation between depressive symptoms and resilience (p < 0.01) and QOL (p < 0.01), were observed after the psychotherapeutic intervention.
