Omitting the excluded participants, 35 intervention group and 36 control group participants were asked to complete the Hospital Anxiety and Depression Scale and Universal Uncertainty in Illness Scale (UUIS) before the psychoeducational intervention (baseline, hereafter \u201cBL \u201c) as well as 1 and 3\u00a0months later. Then, a 2 group (intervention and control groups)\u00a0\u00d7\u00a03 time points (BL and 1 and 3\u00a0months post-intervention) mixed models repeated measures (MMRM) analysis was implemented.<\/jats:p><\/jats:sec><jats:sec id=\"S1478951523001372_sec3c\"><jats:title>Results<\/jats:title><jats:p>Analysis confirmed interaction between 2 group\u00a0\u00d7\u00a03 time points for depression, anxiety, and UUIS.

Meanwhile, in the control group, the depression score was significantly higher at 3\u00a0months post-intervention compared to pre-intervention. The anxiety scores and UUIS of the same group were not significantly different between 1 and 3\u00a0months post-intervention. The effect size values 3\u00a0months post-intervention were \u22120.57 for depression, \u22120.25 for anxiety, and 0.05 for uncertainty.<\/jats:p><\/jats:sec><jats:sec id=\"S1478951523001372_sec4d\"><jats:title>Significance of results<\/jats:title><jats:p>Pretreatment psychoeducation reduced depression, anxiety, and uncertainty in the intervention group of patients with breast cancer compared to the control group.
