Abstract:

Objective To explore distinct trajectories of psychological distress on breast cancer patients from diagnosis to early survivorship,and to investigate whether sociodemographic factors,disease related factors,and personality characteristics can predict trajectories of psychological distress. Methods A prospective study was conducted. Breast cancer patients,who met inclusion and exclusion criteria,were followed up at 6 different timepoints,namely before surgery（T1）,before chemotherapy（T2）,after first chemotherapy（T3）,middle of chemotherapy（T4）,end of chemotherapy（T5）,and 2 months after chemotherapy（T6）. General information,personality,and psychological distress of patients were evaluated. Growth mixture modeling was used to identify trajectory patterns of psychological distress. Logistic regression was used to identify predictors of psychological distress trajectories. Results 3 distinct trajectories were identified and named as “high-stable distress group”“decreasing distress group” and “low-stable distress group”,accounting for 5.3%,57.2%,37.5%,respectively. Occupation（χ²=6.508,P=0.089）,income（χ²=5.237,P=0.073）,and personality（χ²=40.382,P<0.001） have effects on distress trajectories. But only personality was identified in Logistic regression as an independent predictor of psychological distress trajectories. Conclusion Breast cancer patients showed various psychological distress trajectories patterns from diagnosis to early survivorship. Most patients experienced low distress and had good adjustment following cancer diagnosis. Patients who belonged to depressive temperament were more likely to experience high-stable distress and should be given more attention.
