Acute stress trajectories 1 year after a breast cancer diagnosis
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. © 2015, Springer-Verlag Berlin Heidelberg.

AI-generated analysis
🎯 Relevance Assessment: After careful analysis, this paper does not meet the primary inclusion criteria for this systematic review on PTSD symptom trajectories.
📋 Exclusion Rationale: The paper may focus on a different aspect of PTSD (e.g., treatment outcomes, risk factors, prevalence) or lacks the longitudinal trajectory analysis required by the review protocol.
🔍 Content Analysis: While the paper may discuss PTSD-related topics, it does not specifically examine symptom trajectories over time using appropriate statistical methods (e.g., growth curve modeling, latent class analysis).
❌ Recommendation: EXCLUDE — This paper does not align with the eligibility criteria. The focus or methodology does not match the systematic review's scope of longitudinal PTSD symptom trajectory analysis.
