Abstract
Purpose
The purpose of this study was to evaluate the longitudinal trajectories of acute stress reactions over the course of diagnosis, treatment, and follow-up assessments in a group of non-metastatic breast cancer patients during five different moments of the illness process, and to identify psychological predictors of the trajectories.
Methods
The sample was formed by 102 non-metastatic breast cancer patients treated with adjuvant chemotherapy. Latent growth mixture models (LGMM) were used to identify latent classes, and we used multinomial logistic regression in a conditional model to examine predictors to differentiate between trajectories.
Results
We identified four different groups according to their trajectories: (1) a resilient group, (44.5 %); (2) a mild acute stress group, (40.6 %); (3) a delayed–recovery group (11.9 %); and (4) a chronic acute stress group (2.9 %). Moreover, anxious preoccupation showed the strongest significant effects in predicting each class, whereas cognitive avoidance and type C personality had moderate effects for participants in the mild acute stress group.
Conclusions
This study demonstrates that the majority of breast cancer patients in our study were resilient, with only a small percentage showing chronic acute stress. Because coping strategies, specifically anxious preoccupation, and not more stable variables played a main role in the prediction of acute stress trajectories, future preventive interventions should center in promoting more adaptive coping strategies in breast cancer patients.
