Of the 250 eligible participants, 125 caregivers were randomly allocated to the intervention group (receiving DCIRS) and 125 to the waitlist control group. Outcomes, including benefit finding, depressive symptoms, self-efficacy, and coping styles, were assessed at baseline (T0), 6 weeks (T1), and 12 weeks (T2). Generalized estimating equations (GEE) was used to evaluate changes over time and between-group differences, while path analysis examined mediation pathways.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      At 12 weeks, the intervention group showed significant within-group improvements in coping, self-efficacy, and benefit finding (all\n                      <jats:italic toggle=\"yes\">p<\/jats:italic>\n                      \u2009&lt;\u20090.05 for group\u2009\u00d7\u2009time interaction).
